Description

[0001] This application claims priority to Chinese Patent Application No. 202520618063.7, filed on April 2, 2025, entitled “Pruning Machine”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of pruning tools, and more particularly to a pruning tool. Background Technology

[0003] Currently, in the field of horticultural pruning, pruning tools are widely used to prune the branches and leaves of plants such as flowers, trees, and shrubs to control plant height and shape, maintain the neatness and beauty of the overall landscape, and promote healthy plant growth. In existing technologies, when using pruning tools, users typically hold the handles with both hands, positioning the cutting plane roughly at the desired pruning height or trajectory. They then activate the drive mechanism to propel the blades at high speed, moving them slowly along the top and side of hedges or shrubs to complete continuous pruning. During this process, users primarily rely on visual observation of the blades' relative position to the ground, fence, or plant tops, or on their own experience to control the tool's posture and trajectory.

[0004] However, in practice, the cutting plane of the trimming tool blade is easily affected by factors such as changes in the user's grip posture, wrist rotation, terrain undulations, and operator fatigue, causing it to deflect. When the cutting plane deflects, the user often needs to change posture (e.g., by lowering their head, turning to the side, or stepping back) and repeatedly observe the relative position of the blade and the object being trimmed from different angles to determine whether the current trimming is maintaining the desired level or reference direction. This method makes it difficult for the user to continuously monitor the actual cutting situation in front of the blade in a timely manner, and in situations requiring precise horizontal trimming (such as trimming the tops of hedges or shrubs), it is more likely to lead to inconsistent trimming heights and uneven cutting lines, thus affecting the neatness and overall appearance of the trimming effect. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one of the shortcomings of the prior art and provide a trimming tool to improve the user experience and the quality of trimming.

[0006] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention.

[0007] According to a first aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The casing has a protective plate on it; Both the cutting mechanism and the driving mechanism are mounted on the housing. The cutting mechanism has a cutting plane, and the driving mechanism is configured to drive the cutting mechanism to operate. An indicating mechanism, located on the protective plate, is configured to indicate the deflection state of the cutting plane relative to the reference plane; Here, a straight line extending along the length of the cutting plane and parallel to the reference plane is taken as the deflection axis, and the deflection state is the state in which the cutting plane deflects relative to the reference plane around the deflection axis.

[0008] In this embodiment, during the use of the pruning tool, the user holds the housing with both hands, aligning the protective plate and the indicator mechanism on the protective plate towards the target to be pruned. Driven by the drive mechanism, the cutting mechanism operates and forms a cutting plane for pruning. During pruning, the user moves the pruning tool along the top and side of the hedge or shrub, so that the cutting plane roughly conforms to the expected reference plane. When the posture of the pruning tool changes due to factors such as wrist rotation or changes in grip posture, the cutting plane deflects relative to the reference plane around a deflection axis extending along its length and parallel to the reference plane. The indicator mechanism on the protective plate indicates the deflection state of the cutting plane, thereby providing the user with real-time, visual posture feedback within the field of vision in front of the tool. The user does not need to frequently change their posture (such as looking down, turning to the side, or backing away) or rely solely on experience to judge, but can directly understand the tilt angle of the current cutting plane relative to the reference plane by observing the state of the indicator mechanism.

[0009] By arranging an indicator mechanism at the protective plate position and defining the deflection axis with a straight line extending along the length of the cutting plane and parallel to the reference plane, a unified geometric definition and intuitive indication of the deflection state of the cutting plane relative to the reference plane is achieved. Users can continuously observe the deflection direction and degree of the blade in their forward field of vision while facing the object being trimmed. Through real-time posture feedback, users can instantly and accurately adjust their grip and the posture of the trimming tool to ensure that the cutting plane is always as close as possible to the desired reference plane (such as a horizontal plane), eliminating the need to frequently look down or back at the tool's rear position. This reduces the number of eye contact changes and body position adjustments, significantly reducing accidental deflection caused by wrist rotation, posture changes, terrain effects, or fatigue. For the operator, the indicator mechanism provides objective auxiliary judgment criteria, making it easier to master the skill of maintaining horizontal trimming, reducing the learning curve, and minimizing the time spent repeatedly confirming and adjusting the cutting plane's posture. Users can perform trimming operations more smoothly and continuously without stopping to adjust or rework due to uneven trimming, which helps maintain the cutting plane close to the predetermined reference plane, improves the consistency of trimming height and cutting lines, and enhances the neatness and appearance of the trimming effect.

[0010] In some embodiments of this disclosure, based on the foregoing scheme, the trimming tool further includes: A horizontal detection mechanism, connected to an indicating mechanism, is configured to detect the deflection state of the cutting plane relative to a reference plane and output a detection signal. The control mechanism is configured to control the operating status of the indicator mechanism based on the detection signal.

[0011] In this embodiment, during the operation of the trimming tool, the horizontal detection mechanism is electrically connected to the indicating mechanism to acquire the deflection state of the cutting plane relative to the reference plane in real time. A corresponding detection signal is then output and transmitted to the control mechanism. Upon receiving the detection signal, the control mechanism adjusts the operating state of the indicating mechanism according to the deflection state, ensuring that the indicating mechanism reflects the current deflection. This allows for a direct and intuitive output of the deflection detection results to the user without altering the tool's basic structure or operating method.

[0012] By introducing a horizontal detection mechanism and a control mechanism, the horizontal detection mechanism can automatically detect the deflection angle of the cutting plane relative to the user-defined reference plane in real time. The detection signal is transmitted to the control mechanism, which drives the indicator mechanism to work, providing intuitive feedback on the current deflection status. The control mechanism controls the working state of the indicator mechanism based on the detection signal, which helps reduce reliance on user experience and subjective judgment, and reduces operational errors. The horizontal detection mechanism, control mechanism, and indicator mechanism form a closed-loop system. The detection signal is processed quickly and converted into an indication status with low feedback delay. In situations requiring precise horizontal or vertical trimming, users can more easily control the cutting plane within a range close to the target reference plane, thereby improving the consistency of trimming height and cutting lines, and enhancing the overall neatness and appearance of the trimming effect.

[0013] In some embodiments of this disclosure, based on the foregoing scheme, the reference plane includes a first reference plane and / or a second reference plane; The first reference plane is the plane in which the cutting plane is located when the cutting plane is parallel to the horizontal plane; The second reference plane is the plane in which the cutting plane is located when the cutting plane is perpendicular to the horizontal plane.

[0014] In this embodiment, the reference plane is explicitly defined as the plane where the cutting plane is parallel to or perpendicular to the horizontal plane, so that the judgment of the cutting plane deflection has a clear and unified geometric reference. By defining the first reference plane (the plane when the cutting plane is horizontal) and the second reference plane (the plane when the cutting plane is perpendicular), the indicating mechanism can serve the two most commonly used and precise trimming conditions, meet the diverse needs of different trimming scenarios for the reference direction, and improve the versatility and practicality of the tool.

[0015] In some embodiments of this disclosure, based on the foregoing scheme, the indicating mechanism includes a set of light panels; The light panel is mounted on the protective panel.

[0016] In this embodiment, the user moves the trimming tool along the top of a hedge or shrub. When the cutting plane deviates from the reference plane due to wrist rotation, changes in grip posture, or terrain undulations, the detection signal output by the horizontal detection mechanism is processed by the control mechanism, and the display status of the light panel changes accordingly. The user can directly see the change of the light panel on the protective plate when facing the trimming target, thereby obtaining real-time information on the current deflection of the cutting plane and adjusting the posture of the trimming tool according to the display status of the light panel to bring the cutting plane back close to the target reference plane.

[0017] By positioning the light panel on the protective plate and placing it in the same forward field of view as the cutting mechanism, users can observe the deflection between the cutting plane and the reference plane simultaneously during trimming without shifting their line of sight, compared to prompts that require looking down or back. By changing the display state of the light panel when deflection occurs, deflection information that previously relied on visual estimation and experience can be transformed into intuitive visual cues. This allows users to promptly correct the posture of the trimming tool, reducing inconsistencies in trimming height and uneven cutting lines, improving the accuracy and consistency of trimming operations, and simultaneously reducing the operational burden.

[0018] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism includes at least two sets of light panels; At least two sets of light panels are installed on the protective plate, and the projections of any two sets of light panels on the plane of the protective plate form a predetermined angle.

[0019] In this embodiment, the indicating mechanism includes at least two sets of light panels mounted on the protective plate, with a predetermined angle formed between the projections of the different light panels onto the plane of the protective plate. During trimming, the user holds the trimming tool with both hands, and the protective plate and its multiple sets of light panels are located within the field of vision in front of the cutting plane. After the horizontal detection mechanism outputs the deflection state of the cutting plane relative to the reference plane to the control mechanism, the control mechanism can control one or more sets of light panels in the corresponding area to change the display for different deflection directions or different posture ranges, thereby providing differentiated indication of the deflection state in different light panel areas on the protective plate for different directions or ranges. By observing which set of light panels changes, the user can determine the direction of the cutting plane and the deflection area it falls within, and accordingly adjust the left and right swing of the trimming tool.

[0020] This setup achieves two key benefits. First, by arranging at least two sets of light panels at a predetermined angle on the protective plate, each set of light panels corresponds to different indicating directions or areas on the planar projection, thus realizing a spatially "zonal display" of deflection information. This allows users to intuitively distinguish the direction and approximate degree of deflection. Second, by controlling the display changes of only some light panels or a portion of the light panels, rather than uniformly changing the state of all light panels, more precise posture cues can be provided without increasing structural complexity. This allows users to quickly identify which side the current cutting plane is deflected to and whether it exceeds the expected range while maintaining a forward-looking line of sight. This improves the accuracy and response speed of trimming posture adjustments, further enhancing the straightness of the trimming lines and the consistency of the overall trimming effect.

[0021] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism includes at least two sets of light panels; At least two sets of light panels are installed on the protective plate, and the projections of at least two sets of light panels on the plane of the protective plate are parallel to each other.

[0022] In this embodiment, the projections of each light panel onto the protective plate plane are parallel to each other, and multiple groups of light panels form several indicator strips extending in the same direction in the user's field of vision. When the cutting plane deviates relative to the reference plane, the detection signal output by the horizontal detection mechanism is processed by the control mechanism, causing differences in the working state between different light panels. For example, only the display state of one or some light panels may be changed, or different light panels may exhibit different working responses in different deflection ranges. When facing the object to be trimmed, the user can directly observe the correspondence of these parallel light panels in the length or width direction, and judge the direction and approximate degree of deviation of the current cutting plane from the reference plane based on which group of light panels changes and the range of change, thereby adjusting the posture of the trimming tool.

[0023] This setup serves two purposes. First, the parallel distribution of multiple light panels is equivalent to setting several parallel "reference lines" at the front of the tool, enabling continuous indication of the deflection of the cutting plane in a single direction. Even with slight changes in the user's viewing angle, the parallel geometric relationship of each light panel remains stable, which helps improve the readability and consistency of the indication information. Second, by introducing differentiated working responses between the parallel light panels, different deflection ranges or degrees of deflection can be mapped to different light panels or combinations of light panels, achieving hierarchical display of deflection information in the same direction. This makes it easier for users to judge whether the deflection exceeds the allowable range and to make timely posture corrections, which helps improve the trimming height and the straightness of the cutting lines, and improves the neatness and appearance of the trimming effect.

[0024] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism includes at least two sets of light panels; In this configuration, the output terminal of one set of lamp panels is electrically connected to the input terminal of the other set of lamp panels in sequence.

[0025] In this embodiment, the series structure, in which the output and input terminals of adjacent lamp boards are sequentially connected, allows multiple groups of lamp boards to transmit and control signals through cascading. This eliminates the need for separate control lines for each group of lamp boards, reducing the number of wiring harnesses and control port usage, simplifying the electrical connection structure, and lowering wiring complexity and assembly difficulty, thereby contributing to lower overall manufacturing costs. Furthermore, the series connection facilitates adding or removing lamp boards as needed. When it is necessary to expand the indicator area or increase the deflection display resolution, only lamp board modules need to be added to the series link, providing good scalability. In addition, the display signal is sequentially transmitted and responded to along the series path of the lamp boards, allowing users to quickly determine the current deflection state by the number or distribution of lit lamp boards, thereby adjusting the trimming posture more accurately and efficiently, and improving the consistency and precision of the trimming effect.

[0026] In some embodiments of this disclosure, based on the aforementioned scheme, a first handle and a second handle are provided on the housing; The first handle is located at one end of the housing near the cutting mechanism and the protective plate; the second handle is located at one end of the housing away from the cutting mechanism and the protective plate. The display surface of the indicator mechanism forms a first included angle with the cutting plane; wherein the first included angle is greater than or equal to 20° and less than 90°; And / or, A reference plane perpendicular to the cutting plane S0 forms an inclined angle with a cross-section extending along the length direction of the first handle; wherein the inclined angle is in the range of 0° to 15°. And / or, The bottom of the indicating mechanism near the housing and the top of the grip of the first handle are set at a preset plane, and the preset plane and the cutting plane are set at a second angle, which is between 0° and 90°. And / or, The plane containing the line connecting the top of the first handle and the top of the protective plate forms a third angle with the horizontal plane containing the top of the first handle; wherein the third angle is between 10° and 45°. And / or, The plane containing the line connecting the vertex of the side of the first handle and the vertex of the side of the protective plate forms a fourth angle with the cutting plane; wherein the angle of the fourth angle is between 0° and 35°. And / or, On the projection plane perpendicular to the cutting plane, the widest distance of the projection of the first handle is the first distance; the widest distance of the projection of the indicating mechanism is the second distance. The first distance is between 190mm and 250mm; the second distance is between 100mm and 250mm, and the ratio between the first distance and the second distance is between 1:1 and 1:2.5.

[0027] In this embodiment, by placing the first handle at one end of the housing near the cutting mechanism and the protective plate, and the second handle at the other end away from the cutting mechanism and the protective plate, two grip positions distributed front and back can be formed on the housing. This allows the user's hands to bear force separately along the length of the housing when holding the pruning tool, which helps stabilize the overall posture of the machine and reduce unilateral force during pruning. When fine-tuning the posture of the cutting plane in space is required, the user can achieve more precise adjustments by coordinating the operation of the first and second handles, making it easier to maintain the cutting plane close to the target reference plane. By forming a first angle between the display surface of the indicator mechanism and the cutting plane, and limiting the first angle A to greater than or equal to 20° and less than 90°, it is possible to avoid the indicator information being obscured by the cutting area or plant when the display surface is approximately parallel to the cutting plane. It also avoids the display surface being too close to the vertical direction, which would require the user to rotate their wrist or line of sight significantly to observe the indicator information.

[0028] This design ensures that, in a normal trimming posture, the display surface is positioned so that the user can observe it by looking down naturally or by slightly turning their gaze. This allows the user to focus on the cutting trajectory and deflection indicator without significantly altering their grip.

[0029] By limiting the tilt angle B of the first handle relative to a reference plane perpendicular to the cutting plane to the range of 0° to 15°, the first handle can have a moderate tilt while maintaining a basic alignment with the housing direction. This reduces the twisting range of the wrist joint when the user holds the handle, thus reducing fatigue during prolonged operation. Simultaneously, the slight tilt of the first handle allows for smoother and more controllable changes in the trimming tool's posture during slight rotation or lifting movements, facilitating fine-tuning of the cutting plane's deflection.

[0030] By defining a preset plane jointly by the bottom of the indicating mechanism near the housing and the top of the first handle grip, and arranging this preset plane at a second included angle with the cutting plane, with the second included angle limited to between 0° and 90°, the relative spatial relationship between the indicating mechanism and the first handle in both the height and front-back directions can be constrained. This ensures that the indicating mechanism is neither too low to be obstructed by the hand or the object being cut, nor too high to affect the tool's center of gravity and field of vision. In this way, with the user's arm naturally extended and the first handle held normally, the area where the preset plane is located falls within the user's easily visible spatial range, facilitating the observation of the cutting area while simultaneously obtaining deflection indication information.

[0031] By making the plane of the line connecting the top of the first handle and the top of the protective plate form a third angle with the horizontal plane where the top of the first handle is located, and limiting this angle to between 10° and 45°, the height difference between the protective plate and the top of the first handle can be reasonably determined in the vertical direction. This ensures that the protective plate has sufficient height to support the indicator mechanism and provide protection, while not being raised too high to affect the user's observation of the environment and the cutting area in front.

[0032] By creating a fourth angle between the plane containing the line connecting the side apex of the first handle and the side apex of the protective plate, and the cutting plane, and limiting this fourth angle to between 0° and 35°, the relative offset between the first handle and the protective plate can be defined laterally. When the fourth angle is close to a reasonable range within this range, the protective plate has a certain amount of lateral deviation relative to the first handle, which reduces the obstruction of the indicator mechanism by the gripper, while avoiding excessive lateral offset that would cause significant torque to be generated in the trimming tool under lateral force, thus affecting operational stability.

[0033] By setting the maximum projection distance of the first handle as a first distance on a projection plane perpendicular to the cutting plane, and limiting the first distance to a range of 190mm to 250mm, while setting the maximum projection distance of the indicating mechanism as a second distance, and limiting the second distance to a range of 100mm to 250mm, and constraining the ratio between the first distance and the second distance to be 1:1 to 1:2.5, a reasonable width ratio can be established between the gripping area and the indicating area. On the one hand, the range of the first distance ensures that the first handle has sufficient grip width to accommodate different hand shapes and gloved situations, without affecting grip stability due to being too narrow or making the tool cumbersome due to being too wide; on the other hand, the range of the second distance ensures that the indicating mechanism has sufficient width to accommodate signal indicating elements, without obstructing the field of vision or significantly increasing the front-end load due to being too wide.

[0034] In some embodiments of this disclosure, based on the foregoing scheme, the trimming tool further includes: The first lead, one end of which is electrically connected to the horizontal detection mechanism, is configured to transmit the deflection signal of the cutting plane relative to the reference plane obtained by the horizontal detection mechanism. The control mechanism is electrically connected to the other end of the first lead, and the control mechanism is configured to output a display signal based on the deflection signal. The second lead has one end electrically connected to the control mechanism and the other end electrically connected to the input terminal of any set of lamp panels. The second lead is configured to load the display signal onto the lamp panel.

[0035] In this embodiment, by setting a first lead, a control mechanism, and a second lead, the structure divides the functions between the horizontal detection mechanism and the lamp board in terms of electrical connection: one end of the first lead is electrically connected to the horizontal detection mechanism and is used to specifically transmit the deflection signal of the cutting plane relative to the reference plane obtained by the horizontal detection mechanism, so that the deflection signal is transmitted along an independent line after leaving the horizontal detection mechanism, which helps to reduce the influence of external interference on the deflection signal; the control mechanism is electrically connected to the other end of the first lead and generates a display signal for driving the indicator mechanism based on the deflection signal, realizing the conversion and logic processing of the deflection signal and the display signal; one end of the second lead is electrically connected to the control mechanism, and the other end can be selected to extend to the middle area or the side area of ​​the protective plate according to the structural layout of the protective plate, and is electrically connected to the input end of any group of lamp boards, so that the display signal can be flexibly loaded onto the lamp boards in different positions, thereby adjusting the installation position of the lamp board without changing the relative position of the horizontal detection mechanism and the control mechanism, so as to adapt to different shapes of protective plates or different indicator area designs. In this way, while ensuring a clear and reliable transmission path for the deflection signal, the light panel can be placed closer to the cutting area and in a position that is easy for users to observe directly. This is beneficial for achieving real-time and intuitive indication of the deflection status of the cutting plane, reducing the user's reliance on subjective visual observation and experience judgment.

[0036] In some embodiments of this disclosure, based on the aforementioned scheme, the lamp board has multiple groups of lamp beads; The operating status of the indicator mechanism includes the brightness and / or position of the LED group, and / or the display color of the LED group.

[0037] In this embodiment, by setting multiple LED groups on the light panel and designing the working state of the indicator mechanism to include the brightness and / or position of the LED groups and / or their display colors, the deflection state of the cutting plane relative to the reference plane can be more precisely and intuitively distinguished within a limited installation space. The combination of multiple working states allows deflection information to be presented in a multi-dimensional visual form, facilitating quick identification of the current deflection status and corresponding adjustments by the user, reducing the probability of misjudgment and improving trimming accuracy and safety. This group control and multi-parameter display method based on multiple LED groups is a functional design for the visual expression of deflection status, not merely a simple decorative or adaptive adjustment to the number, arrangement, or color of the LEDs.

[0038] According to a second aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The casing has a protective plate on it; Both the cutting mechanism and the driving mechanism are mounted on the housing. The cutting mechanism has a cutting plane, and the driving mechanism is configured to drive the cutting mechanism to operate. An indicating mechanism, located on the protective plate, is configured to indicate the deflection state of the cutting plane relative to the reference plane; A horizontal detection mechanism, housed within the housing, is configured to detect the deflection state of the cutting plane relative to a reference plane and output a detection signal. The reference plane includes a first reference plane and / or a second reference plane; The first reference plane is the plane in which the cutting plane is located when the cutting plane is parallel to the horizontal plane; The second reference plane is the plane in which the cutting plane is located when the cutting plane is perpendicular to the horizontal plane.

[0039] In this embodiment, during use, the user holds the housing and operates the trimming tool, aligning the protective plate and its indicator mechanism towards the object to be trimmed. A drive mechanism drives the cutting mechanism mounted on the housing, thereby forming a cutting plane in space for trimming. During trimming, the user adjusts the cutting plane to approximately align with the desired first and / or second reference planes according to the work requirements: when performing top horizontal trimming, the cutting plane is positioned close to the horizontal plane, corresponding to the first reference plane; when performing vertical trimming, the cutting plane is positioned close to the horizontal plane, corresponding to the second reference plane. During trimming, if the cutting plane deviates from the reference planes due to changes in grip, terrain undulations, or operational actions, the horizontal detection mechanism detects the deflection state of the cutting plane relative to the first and / or second reference planes in real time and outputs a detection signal to the connected indicator mechanism. The indicator mechanism indicates the current deflection state at the protective plate position. The user can directly obtain the deflection status between the cutting plane and the reference planes within their field of vision facing the object being trimmed and adjust the tool posture accordingly.

[0040] By setting a cutting mechanism, a driving mechanism, and an indicator mechanism on the protective plate on the housing, and introducing a horizontal detection mechanism connected to the indicator mechanism, the deflection state of the cutting plane relative to the reference plane is detected and indicated. On the one hand, the posture of the cutting plane is associated with a clear geometric reference, which facilitates the selection of the appropriate reference plane in different working scenarios (such as top horizontal trimming and side vertical trimming). On the other hand, the deflection state is automatically detected by the horizontal detection mechanism and provided to the indicator mechanism in the form of a detection signal. The indication is completed directly in the area in front of the protective plate, avoiding the problem of relying solely on the operator to visually observe the blade posture or repeatedly adjust body position to judge the horizontal / vertical degree, thus reducing human subjective error.

[0041] In some embodiments of this disclosure, based on the aforementioned scheme, the housing includes a first housing and a second housing; a first handle is disposed on the first housing, a second handle is disposed on the second housing, and the first housing and the second housing are rotatably connected; A sensing mechanism, disposed on the second housing, is configured to acquire relative rotation information of the second housing or the first housing and output a rotation signal; The control mechanism, based on the rotation signal, controls the indicating mechanism to indicate in its corresponding area according to the detection signal.

[0042] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism includes at least one lamp panel; the lamp panel has multiple groups of lamp beads; The operating status of the indicator mechanism includes the brightness and / or position of the LED group, and / or the display color of the LED group.

[0043] In some embodiments of this disclosure, based on the aforementioned scheme, the protective plate includes a first protective layer and a second protective layer arranged sequentially along the front-back direction of the trimming tool; wherein, the first protective layer faces the cutting mechanism, the second protective layer faces the operator, the first protective layer and the second protective layer are spaced apart, and the first protective layer and the second protective layer form a receiving space for accommodating the indicating mechanism, the indicating mechanism being at least partially disposed within the receiving space.

[0044] In some embodiments of this disclosure, based on the aforementioned scheme, the trimming tool further includes a first damping unit. One end of the first damping unit is connected to the drive mechanism, and the other end of the first damping unit is disposed inside the housing corresponding to the drive mechanism, with a pre-reserved gap between the first damping unit and the inner wall of the housing.

[0045] In some embodiments disclosed herein, based on the aforementioned scheme, the first damping unit is made of a flexible material.

[0046] In some embodiments disclosed herein, based on the aforementioned scheme, the first shock-absorbing unit has a hollowed-out portion.

[0047] In some embodiments of this disclosure, based on the aforementioned scheme, the trimming tool further includes a second damping unit; the second damping unit is disposed between the housing and the drive mechanism; and is configured to mitigate the effect of the drive mechanism's movement on the housing.

[0048] In some embodiments of this disclosure, based on the aforementioned scheme, the thickness of the second shock-absorbing unit is between 2.9 and 3.5 mm along the length direction of the first handle.

[0049] In some embodiments of this disclosure, based on the aforementioned scheme, the trimming tool further includes a third shock-absorbing unit; the third shock-absorbing unit is disposed between the housing and the cutting mechanism.

[0050] In some embodiments of this disclosure, based on the aforementioned scheme, the trimming tool further includes a fourth damping unit; the fourth damping unit is disposed between the housing and the drive mechanism and is configured to mitigate the influence of the drive mechanism on the housing.

[0051] In some embodiments disclosed herein, based on the aforementioned scheme, the material of the fourth damping unit is a soft rubber damping pad.

[0052] In some embodiments of this disclosure, based on the aforementioned scheme, the trimming tool further includes a fifth damping unit; the fifth damping unit is disposed between the housing and the drive mechanism and is configured to mitigate the influence of the drive mechanism on the housing.

[0053] In some embodiments disclosed herein, based on the aforementioned scheme, the material of the fifth damping unit is a hard rubber damping pad.

[0054] According to a third aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The casing has a protective plate on it; A cutting mechanism is mounted on the housing and has a cutting plane. A horizontal detection mechanism, mounted on the housing, is configured to detect the deflection state of the cutting plane relative to the reference plane and output a detection signal. The first lead, one end of which is electrically connected to the horizontal detection mechanism, is configured to transmit the detection signal acquired by the horizontal detection mechanism; The control mechanism, located on the housing and electrically connected to the other end of the first lead, is configured to output a display signal based on the detection signal; The drive mechanism is configured to drive the cutting mechanism to operate; An indicating mechanism is provided on the housing; The second lead has one end electrically connected to the control mechanism and the other end connected to the indicator mechanism. The second lead is configured to load a display signal to the indicator mechanism. The indicating mechanism is configured to indicate the deflection state of the cutting plane relative to the reference plane based on the display signal.

[0055] In this embodiment, during use, the user holds the housing to operate the trimming tool, driving the mechanism to rotate or reciprocate the cutting mechanism mounted on the housing, thereby forming a cutting plane for trimming. During trimming, the orientation of the cutting plane relative to the reference plane will deflect due to factors such as terrain undulations and changes in hand posture. A horizontal detection mechanism mounted on the housing detects the deflection state of the cutting plane relative to the reference plane in real time and outputs a detection signal, which is transmitted to the control mechanism on the housing via a first lead. The control mechanism generates a display signal corresponding to the current deflection state based on the detection signal, and then loads the display signal to the indicator mechanism via a second lead, so that the indicator mechanism synchronously provides a visual indication of the deflection state of the cutting plane during tool operation. The user can determine whether the current orientation needs adjustment based on the display of the indicator mechanism while in a normal holding and operating state, and correct the orientation of the trimming tool accordingly.

[0056] By sequentially arranging a horizontal detection mechanism, a first lead, a control mechanism, and a second lead and an indicator mechanism on the housing, detection, signal transmission, signal processing, and deflection indication are implemented in segments. On the one hand, the deflection state of the cutting plane relative to the reference plane is reliably acquired in the form of a detection signal and transmitted to the control mechanism for processing via the first lead, which helps to ensure a clear signal transmission path and strong anti-interference capability. On the other hand, the control mechanism outputs a unified display signal, which is then loaded to the indicator mechanism via the second lead, allowing for flexible arrangement of the indicator mechanism without changing the installation position of the horizontal detection mechanism, thus improving the adaptability of the overall structure.

[0057] The indicating mechanism displays the deflection status of the cutting plane based on the signal, allowing operators to know in real time whether the current posture deviates from the reference plane without relying on experience or visual inspection. This enables timely correction of the trimming action, improving the straightness and consistency of the trimming trajectory and reducing the risk of misoperation.

[0069] In some embodiments disclosed herein, based on the aforementioned scheme, the material of the fifth damping unit is a hard rubber damping pad.

[0070] In some embodiments of this disclosure, based on the aforementioned scheme, the housing has a first housing with a first handle and a second housing with a second handle; the first handle is located at one end close to the cutting mechanism, and the second handle is located at one end away from the cutting mechanism; the indicating mechanism is located on the protective plate, or the indicating mechanism is located on the housing corresponding to the first handle and the second handle.

[0071] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism is disposed on the protective plate, one end of the first lead is electrically connected to the horizontal detection mechanism, and the first lead is configured to transmit the deflection signal of the cutting plane relative to the reference plane obtained by the horizontal detection mechanism. The control mechanism is electrically connected to the other end of the first lead, and the control mechanism is configured to output a display signal based on the deflection signal. One end of the second lead is electrically connected to the control mechanism, and the other end of the second lead extends to the central region of the protective plate and is electrically connected to the indicator mechanism; or, the other end of the second lead extends to the side region of the protective plate and is electrically connected to the indicator mechanism; wherein the second lead is configured to load a display signal to the indicator mechanism.

[0072] In some embodiments of this disclosure, based on the foregoing scheme, the second handle is rotatably connected to the housing; the trimming tool further includes a sensing mechanism; the sensing mechanism is disposed on the housing, and is configured to acquire rotation information of the second handle and output a rotation signal; the control mechanism controls the indicating mechanism to indicate in its corresponding area according to the detection signal based on the rotation signal. In some embodiments of this disclosure, based on the foregoing scheme, the housing has a first housing with a first handle and a second housing with a second handle; The first handle is located at the end of the housing closest to the cutting mechanism, and the second handle is located at the end of the housing furthest from the cutting mechanism. The protective plate is located at one end of the housing near the cutting mechanism; the indicating mechanism is located on the protective plate, or the indicating mechanism is located on the housing between the first handle and the second handle.

[0073] In this embodiment, by providing a first housing with a first handle and a second housing with a second handle, and placing the first handle near the cutting mechanism and the second handle away from the cutting mechanism, the user can adopt a two-handed grip posture with a front-to-back distribution during trimming. The first handle, being closer to the cutting mechanism, facilitates precise control of the cutting plane's height and posture, while the second handle provides auxiliary support and stability, reducing single-handed stress and posture sway during extended operation. Simultaneously, by placing a protective plate at the end of the housing near the cutting mechanism and placing the indicator mechanism on the protective plate or on the housing between the first and second handles, the indicator mechanism is positioned within the user's field of vision, between the two handles or in the front area. This allows the user to directly observe the indicator information in a normal posture facing the trimming object and holding the trimming tool with both hands, without needing to significantly turn their body or look down to check the rear, thus improving the visibility and timeliness of the deflection status indication. The protective plate not only blocks flying debris and protects the cutting mechanism but also provides a stable mounting reference for the indicator mechanism, organically combining safety protection and posture indication functions in the front area. The overall arrangement of the first handle, second handle, protective plate, and indicator mechanism is a collaborative design formed by comprehensively considering force balance, human-machine grip posture, safety protection, and field of vision. It can effectively improve the control stability and the intuitiveness of deflection indication during the trimming process, rather than a simple adaptive adjustment to the handle position or display position.

[0074] In some embodiments of this disclosure, based on the aforementioned scheme, the first housing and the second housing are rotatably connected; A sensing mechanism, disposed on the second housing, is configured to acquire relative rotation information of the second housing or the first housing and output a rotation signal; The control mechanism, based on the rotation signal, controls the indicating mechanism to indicate in its corresponding area according to the detection signal.

[0075] In this embodiment, the operator can primarily hold the second handle, making the second handle and its corresponding housing relatively stable in space. By applying force, the first housing with the first handle can be rotated relative to the second housing with the second handle, adapting to different working postures, working directions, and hand shape requirements. Thus, when pruning branches at high, low, or side positions, the wrist joint and forearm can be placed within a more suitable angle range, thereby helping to reduce fatigue caused by prolonged operation and improve grip stability.

[0076] Before actual use, the operator can pre-adjust the angle of the first housing corresponding to the first handle relative to the second housing corresponding to the second handle, based on the height and spatial orientation of the target branch. During the aforementioned rotation, the sensing mechanism acquires the relative rotation information of the second or first housing and outputs a rotation signal. The control mechanism selects the indication area corresponding to the current posture accordingly and, combined with the detection signal output by the horizontal detection mechanism, drives the indication mechanism to display in the corresponding area, guiding the operator to adjust the overall posture of the pruning tool so that the cutting plane is within the desired deflection range. Furthermore, during the pruning process, when the target object or the direction of operation changes, the operator can continue to fine-tune the angle. The indication mechanism updates the display result synchronously, reducing the operator's reliance on subjective feel in judging the direction and degree of deflection of the cutting plane. This achieves more precise control of the cutting posture while maintaining grip comfort, thus balancing ergonomic comfort and cutting posture control accuracy, and improving operability and consistency under different postures.

[0077] In some embodiments of this disclosure, based on the foregoing scheme, the indicating mechanism includes at least one set of light panels; The end of the second lead furthest from the control mechanism is electrically connected to the input terminal of any set of lamp panels; The second lead is configured to load the display signal onto the lamp panel.

[0078] In this embodiment, with the above-described configuration, the end of the second lead furthest from the control mechanism can selectively extend to the central or side region of the protective plate and be electrically connected to the input terminal of any set of light panels, allowing the display signal to be flexibly loaded onto light panels at different positions. On one hand, the central region is closer to the forward viewing axis of the pruning tool, suitable for providing intuitive deflection instructions to the user in forward pruning scenarios; on the other hand, the side region is easier to avoid partial obstruction by plants, hands, or the housing under certain pruning postures or specific structural layouts, thereby improving the visibility of the light panel under different working conditions. Simultaneously, the second lead serves only as a transmission path for the display signal, guiding the display signal output by the control mechanism to the target light panel in an orderly manner, without changing the installation position of the control mechanism and other circuit units. This facilitates standardized and modular design of the wiring harness arrangement and allows for the reuse of the same control circuit scheme across different models and different protective plate shapes. In some embodiments of this disclosure, based on the aforementioned scheme, the light panel has multiple groups of LED beads; The operating status of the indicator mechanism includes the brightness and / or position of the LED group, and / or the display color of the LED group.

[0079] According to a fourth aspect of the present invention, a trimming tool includes: The housing includes a first housing with a first handle and a second housing with a second handle; wherein the first housing and the second housing are rotatably connected. Both the cutting mechanism and the driving mechanism are mounted on the housing. The cutting mechanism has a cutting plane, and the driving mechanism is configured to drive the cutting mechanism to operate. A horizontal detection mechanism, disposed on the housing, is configured to detect the deflection state of the cutting plane relative to the reference plane and output a detection signal; An indicating mechanism is provided on the housing between the first handle and the second handle, and the indicating mechanism is configured to indicate the deflection state of the cutting plane relative to the reference plane; A sensing mechanism, disposed on the housing, is configured to acquire rotation information of the second housing relative to the first housing and output a rotation signal; The control mechanism compares the detected signals with preset thresholds and outputs a first signal and a second signal; wherein the first signal and the second signal are different in the working state of the indicating mechanism. Based on the rotation signal, a preset area is selected, and the indicating mechanism is controlled to indicate in its corresponding preset area according to the detection signal; Here, a straight line extending along the length of the cutting plane and parallel to the reference plane is taken as the deflection axis, and the deflection state is the state in which the cutting plane deflects relative to the reference plane around the deflection axis.

[0080] In this embodiment, during use, the user holds the first handle and the second handle on the housing respectively, and drives the cutting mechanism to operate through the drive mechanism, so that the cutting plane prunes the target branch. Since the first housing and the second housing are rotatably connected, when the user applies force to rotate the first housing relative to the second housing according to the work requirements and the site conditions, the posture of the first housing relative to the second handle changes accordingly, so that the cutting plane deflects relative to the reference plane around a deflection axis extending along the length direction of the cutting plane and parallel to the reference plane. The sensing mechanism provided on the housing acquires the rotation information of the first housing relative to the second housing during the rotation of the first housing relative to the second housing and outputs a rotation signal (of course, it can also be the rotation information of the second housing relative to the first housing). Based on the rotation signal, the control mechanism selects a preset area corresponding to the current posture on the indicator mechanism, and combines it with the detection signal output by the horizontal detection mechanism, drives the indicator mechanism to display within the selected preset area, so that after adjusting the rotation position of the first housing, the user can still intuitively see the deflection of the cutting plane relative to the reference plane in an area close to the hand, and continue to rotate the angle of the first housing relative to the second housing accordingly, adjusting the cutting plane to a posture close to the expected reference plane.

[0081] By designing a first housing with a first handle to be rotatably connected to a second housing with a second handle, and incorporating a sensing mechanism on the housing to acquire rotational information of the first housing relative to the second housing, a control mechanism selects a preset area for an indicator based on the rotation signal. This, in turn, drives the selected area to indicate the direction of rotation based on a detection signal from a horizontal detection mechanism. This establishes a correspondence between the rotational position of the first housing and the display position of the indicator area, and the indicator information reflecting the deflection state of the cutting plane is visually presented near the user's grip area. In this way, the user can monitor the spatial deflection of the cutting plane in real time without relying solely on visual observation of the blade's posture or subjective experience. By adjusting the rotation angle of the first housing, the user can achieve fine-tuning of the cutting plane's posture. Under different working postures and trimming directions, this helps maintain the cutting plane within an acceptable range close to the reference plane, improving the straightness and consistency of the trimmed lines, reducing the risk of misoperation, and enhancing grip comfort during extended work periods.

[0082] In some embodiments of this disclosure, based on the aforementioned scheme, the preset area includes a first position; when the cross-section of the second handle extending along the length direction of the trimming tool is perpendicular to the cutting plane, the first housing is in the first position; the first housing can rotate relative to the second handle to the first position; in the first position, the control mechanism outputs a first signal and a second signal to the indicating structure based on the detection signal output by the horizontal detection mechanism through a preset threshold comparison, and the first signal and the second signal are different in the working state of the indicating mechanism.

[0083] In some embodiments of this disclosure, based on the aforementioned scheme, when the detection value of the horizontal detection mechanism is greater than or equal to a first threshold at the first position, the indicating mechanism displays a first signal; when the detection value of the horizontal detection mechanism is less than the first threshold, the indicating mechanism displays a second signal; and / or, when the detection value of the horizontal detection mechanism is equal to the first threshold, the indicating mechanism displays a third signal.

[0084] In some embodiments of this disclosure, based on the foregoing scheme, the first housing can also be rotated relative to the second handle to a second position and / or a third position. When the cross-section of the second handle extending along the length direction of the trimming tool is parallel or coplanar with the cutting plane, the first housing is in the second position and / or the third position, and the second position and the third position are arranged opposite to the cross-section of the second handle extending along the length direction of the trimming tool. When the first housing is in the second position and / or the third position, the detection value of the horizontal detection mechanism outputs a first signal and a second signal according to a second threshold. The first signal and the second signal are different in the working state of the indicating mechanism.

[0085] In some embodiments of this disclosure, based on the aforementioned scheme, when the detection value of the horizontal detection mechanism is greater than or equal to a second threshold at the first position, the indicating mechanism displays a first signal; when the detection value of the horizontal detection mechanism is less than the second threshold, the indicating mechanism displays a second signal; and / or, when the detection value of the horizontal detection mechanism is equal to the second threshold, the indicating mechanism displays a third signal.

[0086] In some embodiments of this disclosure, based on the aforementioned scheme, at the third position, the detection value of the horizontal detection mechanism outputs a first signal and a second signal according to a third threshold; the first signal and the second signal have different operating states in the indicating mechanism. When the detection value of the horizontal detection mechanism is greater than the third threshold, the indicating mechanism displays the first signal; when the detection value of the horizontal detection mechanism is less than the third threshold, the indicating mechanism displays the second signal; when the detection value of the horizontal detection mechanism is equal to the third threshold, the indicating mechanism displays the third signal.

[0087] In some embodiments of this disclosure, based on the aforementioned scheme, the lamp board has multiple groups of lamp beads; The operating status of the indicator mechanism includes the brightness and / or position of the LED group, and / or the display color of the LED group.

[0088] In some embodiments of this disclosure, based on the foregoing scheme, the indicating mechanism includes at least one set of light panels; The light panel has multiple groups of LED beads; the indicator mechanism indicates the brightness and / or position of the LED bead groups and / or the working status of the LED bead groups based on the signal loaded by the sensing mechanism.

[0089] In this embodiment, by configuring the indicating mechanism to include at least one set of light panels and arranging multiple groups of LED beads on the light panels, and by having the indicating mechanism control the brightness and / or position and / or color changes of the LED bead groups according to the signal loaded by the sensing mechanism, the deflection state of the cutting plane corresponding to the rotation of the second handle can be graded and visualized within a limited area of ​​the light panel. This allows for more timely and accurate adjustment of the rotation angle of the second handle, restoring the cutting plane to the desired posture.

[0090] In some embodiments of this disclosure, based on the foregoing scheme, the indicating mechanism includes at least one set of light panels; The end of the second lead away from the control mechanism extends to the middle area of ​​the protective plate and is electrically connected to the input terminal of any set of lamp panels; or the end of the second lead away from the control mechanism extends to the side area of ​​the protective plate and is electrically connected to the input terminal of any set of lamp panels.

[0091] According to a fifth aspect of the present invention, a trimming tool is provided, the trimming tool comprising: A housing is provided with a protective plate, a first handle, and a second handle; the first handle is located at one end of the housing near the cutting mechanism and the protective plate; the second handle is located at the other end of the housing away from the cutting mechanism and the protective plate. Both the cutting mechanism and the driving mechanism are mounted on the housing. The cutting mechanism has a cutting plane, and the driving mechanism is configured to drive the cutting mechanism to operate. The indicating mechanism is located on the protective plate or on the housing located between the first handle and the second handle. The indicating mechanism is configured to indicate the deflection state of the cutting plane relative to the reference plane. A horizontal detection mechanism, housed within the housing, is configured to detect the deflection state of the cutting plane relative to a reference plane and output a detection signal. Here, a straight line extending along the length of the cutting plane and parallel to the reference plane is taken as the deflection axis, and the deflection state is the state in which the cutting plane deflects relative to the reference plane around the deflection axis.

[0092] In this embodiment, by providing a protective plate, a first handle, and a second handle on the housing, and arranging the indicator mechanism on the protective plate or on the housing between the first and second handles, the indicator mechanism is positioned close to the cutting mechanism and within the forward field of view between the two handles. When the user holds the trimming tool with both hands and faces the object being trimmed, they do not need to turn around to look back at the rear of the housing or look down to observe the handle's position. They can directly obtain information about the deflection state of the cutting plane relative to the reference plane while observing the cutting plane and its trimming trajectory. Using a straight line extending along the length of the cutting plane and parallel to the reference plane as the deflection axis, the deflection state displayed by the indicator mechanism corresponds to the actual spatial posture change of the blade around this deflection axis. This makes the indication of the deflection direction and degree more intuitive and consistent, allowing the user to promptly correct the trimming tool's posture while holding it naturally, improving the straightness and height consistency of the trimming lines, and reducing operational inconvenience and safety hazards caused by frequent looking down and back. The placement of the aforementioned indicator mechanism is an overall layout formed by comprehensively considering the human-machine field of vision, grip posture, and the definition of the cutting plane deflection axis. It is not a simple adaptive adjustment of arbitrarily installing the display component in a certain position on the housing.

[0093] In some embodiments of this disclosure, based on the aforementioned scheme, the protective plate includes a first protective layer and a second protective layer arranged sequentially along the front-back direction of the trimming tool; wherein, the first protective layer faces the cutting mechanism, the second protective layer faces the operator, the first protective layer and the second protective layer are spaced apart, and the first protective layer and the second protective layer form a receiving space for accommodating the indicating mechanism, the indicating mechanism being at least partially disposed within the receiving space.

[0094] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism is disposed on the protective plate, one end of the first lead is electrically connected to the horizontal detection mechanism, and the first lead is configured to transmit the deflection signal of the cutting plane relative to the reference plane obtained by the horizontal detection mechanism. The control mechanism is electrically connected to the other end of the first lead, and the control mechanism is configured to output a display signal based on the deflection signal. One end of the second lead is electrically connected to the control mechanism, and the other end of the second lead extends to the central region of the protective plate and is electrically connected to the indicator mechanism; or, the other end of the second lead extends to the side region of the protective plate and is electrically connected to the indicator mechanism; wherein the second lead is configured to load a display signal to the indicator mechanism.

[0095] In some embodiments of this disclosure, based on the aforementioned scheme, a first handle is disposed at one end of the housing near the cutting mechanism and the protective plate; a second handle is disposed at one end of the housing away from the cutting mechanism and the protective plate; a first included angle is formed between the display surface of the indicating mechanism and the cutting plane; wherein the first included angle is greater than or equal to 20° and less than 90°.

[0096] In some embodiments of this disclosure, based on the aforementioned scheme, a reference plane perpendicular to the cutting plane forms an inclined angle with a cross-section extending along the length direction of the first handle; wherein the inclined angle is in the range of 0° to 15°.

[0097] In some embodiments of this disclosure, based on the aforementioned scheme, the bottom end of the indicating mechanism near the housing and the top end of the grip portion of the first handle are set with a preset plane, and the preset plane and the cutting plane are set at a second angle, the second angle being between 0° and 90°.

[0098] In some embodiments of this disclosure, based on the aforementioned scheme, the plane containing the line connecting the top of the first handle and the top of the protective plate forms a third angle with the horizontal plane containing the top of the first handle; wherein, the third angle is between 10° and 45°.

[0099] In some embodiments of this disclosure, based on the aforementioned scheme, the plane containing the line connecting the vertex of the side of the first handle and the vertex of the side of the protective plate forms a fourth included angle with the cutting plane; wherein the angle of the fourth included angle is between 0° and 35°.

[0100] In some embodiments of this disclosure, based on the aforementioned scheme, on a projection plane perpendicular to the cutting plane, the widest distance of the projection of the first handle is the first distance; the widest distance of the projection of the indicating mechanism is the second distance; wherein, the value of the first distance is between 190mm and 250mm; the value of the second distance is between 100mm and 250mm, and the ratio between the first distance and the second distance is between 1:1 and 1:2.5.

[0101] According to a sixth aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The casing has a protective plate on it; Both the cutting mechanism and the driving mechanism are mounted on the housing. The cutting mechanism has a cutting plane, and the driving mechanism is configured to drive the cutting mechanism to operate. The indicating mechanism is located on the protective plate, or on the housing located between the protective plate and the drive mechanism; the indicating mechanism is configured to indicate the deflection state of the cutting plane relative to the reference plane; A horizontal detection mechanism, disposed on the housing, is configured to detect the deflection state of the cutting plane relative to the reference plane and output a detection signal; The control mechanism compares the detection signal with a preset threshold and outputs a first signal and a second signal. The first signal and the second signal are different in the working state of the indicator mechanism. The control mechanism then controls the indicator mechanism to indicate the corresponding preset area according to the detection signal. Here, a straight line extending along the length of the cutting plane and parallel to the reference plane is taken as the deflection axis, and the deflection state is the state in which the cutting plane deflects relative to the reference plane around the deflection axis.

[0102] In this embodiment, during use, the operator holds the housing and activates the drive mechanism, which drives the cutting mechanism to perform a cutting operation. When the cutting plane deflects relative to the reference plane due to the operator's posture, the force on the branch, or the wrist swing, the cutting plane deflects around a straight line extending along the length of the cutting plane and parallel to the reference plane as the deflection axis. The horizontal detection mechanism detects this deflection state in real time and outputs a detection signal. The control mechanism compares the detection signal with a threshold to generate a first signal or a second signal, and further controls the indicator mechanism to indicate in its corresponding preset area, so that the working state of the indicator mechanism corresponding to the first signal and the second signal is different (e.g., different on / off states, different indication positions, or different display modes), thereby guiding the operator to adjust the grip angle or working direction in time so that the cutting plane returns to the target deflection range.

[0103] As set up above, the deflection of the cutting plane relative to the reference plane can be provided in real time and intuitively in a graded manner, reducing the operator's reliance on subjective judgment of the cutting posture. This facilitates rapid identification of whether the deflection exceeds the limit and timely correction under different working directions and perspectives, thereby improving cutting safety and operational consistency. Simultaneously, the indicator mechanism is located on the protective plate or in the housing area between the protective plate and the drive mechanism, balancing visibility and protection. This makes the indicator information easier to observe and less susceptible to obstruction or impact from debris, thus reducing misoperation, lowering the risk of jamming / off-center cutting, and improving usability and ergonomics in scenarios involving novices and complex postures. It also reduces the risk of incorrect cutting or repeated trimming due to inaccurate posture judgment.

[0104] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism includes at least one lamp panel; the lamp panel has multiple groups of lamp beads; The operating status of the indicator mechanism includes the brightness and / or position of the LED group, and / or the display color of the LED group.

[0105] In some embodiments of this disclosure, based on the aforementioned scheme, the protective plate includes a first protective layer and a second protective layer arranged sequentially along the front-back direction of the trimming tool; wherein, the first protective layer faces the cutting mechanism, the second protective layer faces the operator, the first protective layer and the second protective layer are spaced apart, and the first protective layer and the second protective layer form a receiving space for accommodating the indicating mechanism, the indicating mechanism being at least partially disposed within the receiving space.

[0106] In some embodiments of this disclosure, based on the aforementioned scheme, the indicating mechanism is disposed on the protective plate, one end of the first lead is electrically connected to the horizontal detection mechanism, and the first lead is configured to transmit the deflection signal of the cutting plane relative to the reference plane obtained by the horizontal detection mechanism. The control mechanism is electrically connected to the other end of the first lead, and the control mechanism is configured to output a display signal based on the deflection signal. One end of the second lead is electrically connected to the control mechanism, and the other end of the second lead extends to the central region of the protective plate and is electrically connected to the indicator mechanism; or, the other end of the second lead extends to the side region of the protective plate and is electrically connected to the indicator mechanism; wherein the second lead is configured to load a display signal to the indicator mechanism.

[0107] In some embodiments of this disclosure, based on the aforementioned scheme, a first handle is disposed at one end of the housing near the cutting mechanism and the protective plate; a second handle is disposed at one end of the housing away from the cutting mechanism and the protective plate; a first included angle is formed between the display surface of the indicating mechanism and the cutting plane; wherein the first included angle is greater than or equal to 20° and less than 90°.

[0108] In some embodiments of this disclosure, based on the aforementioned scheme, a reference plane perpendicular to the cutting plane forms an inclined angle with a cross-section extending along the length direction of the first handle; wherein the inclined angle is in the range of 0° to 15°.

[0109] In some embodiments of this disclosure, based on the aforementioned scheme, the bottom end of the indicating mechanism near the housing and the top end of the grip portion of the first handle are set with a preset plane, and the preset plane and the cutting plane are set at a second angle, the second angle being between 0° and 90°.

[0110] In some embodiments of this disclosure, based on the aforementioned scheme, the plane containing the line connecting the top of the first handle and the top of the protective plate forms a third angle with the horizontal plane containing the top of the first handle; wherein, the third angle is between 10° and 45°.

[0111] In some embodiments of this disclosure, based on the aforementioned scheme, the plane containing the line connecting the vertex of the side of the first handle and the vertex of the side of the protective plate forms a fourth included angle with the cutting plane; wherein the angle of the fourth included angle is between 0° and 35°.

[0112] In some embodiments of this disclosure, based on the aforementioned scheme, on a projection plane perpendicular to the cutting plane, the widest distance of the projection of the first handle is the first distance; the widest distance of the projection of the indicating mechanism is the second distance; wherein, the value of the first distance is between 190mm and 250mm; the value of the second distance is between 100mm and 250mm, and the ratio between the first distance and the second distance is between 1:1 and 1:2.5.

[0113] In some embodiments of this disclosure, based on the foregoing scheme, when the horizontal detection mechanism detects that the deflection value of the cutting plane relative to the reference plane is greater than a first threshold, the indicating mechanism displays a first signal; when the horizontal detection mechanism detects that the deflection value of the cutting plane relative to the reference plane is less than a second threshold, the indicating mechanism displays a second signal; and / or, When the deflection value of the horizontal detection mechanism relative to the cutting plane and the reference plane is equal to the third threshold, the indicating mechanism displays the third signal.

[0114] According to a seventh aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The housing has a first housing with a first handle and a second housing with a second handle, the first housing being movable relative to the second housing between a first position and a second position; A cutting mechanism is mounted on the housing and has a cutting plane. An indicating mechanism, disposed on the housing, is configured to indicate the deflection state of the cutting plane relative to a reference plane; and The control mechanism, located on the housing, is configured such that: in a first position, the control mechanism controls the indicating mechanism to indicate the deflection state of the cutting plane relative to the reference plane in a first preset area; and in a second position, the control mechanism controls the indicating mechanism to indicate the deflection state of the cutting plane relative to the reference plane in a second preset area.

[0115] In this embodiment, during use, the operator holds the first handle and the second handle respectively, and switches the first housing relative to the second housing between a first position and a second position according to the working posture requirements to obtain a suitable grip angle and operating space. During the trimming process, the cutting mechanism forms a corresponding cutting plane under drive, and the indicating mechanism displays the deflection state of the cutting plane relative to the reference plane in real time. When the control mechanism detects that the first housing is in the first position, it drives the indicating mechanism to display in the first preset area; when the first housing switches to the second position, the control mechanism correspondingly switches the display area, so that the indicating mechanism outputs a deflection indication in the second preset area, thereby enabling the operator to read the deflection information and adjust the operation in a timely manner in different grip positions within the area covered by their main line of sight.

[0116] By establishing a correspondence between the display area of ​​the indicator mechanism and two positions of the first housing relative to the second housing, the display position of the deflection information can be automatically adjusted when the machine body shape changes (e.g., grip posture change, relative rotation of the housing). This ensures that the deflection indicator is always in a preset area that is easier to observe, reducing misjudgments and delays caused by changes in viewing angle, obstruction, or deviation of the line of sight. This improves the visibility and consistency of the deflection status indication, allowing operators to quickly correct the cutting plane posture, reducing the risk of accidental cutting, improving operational safety and trimming efficiency, and enhancing ergonomic adaptability under different working conditions.

[0117] In some embodiments of this disclosure, the trimming tool further includes: The horizontal detection mechanism, housed within the housing, is configured to detect the deflection state of the cutting plane relative to the reference plane and output a detection signal. In either the first or second position, the control mechanism is configured to control the indicator mechanism to issue a first display signal based on a first detection signal detected by the horizontal detection mechanism; and to control the indicator mechanism to issue a second display signal based on a second detection signal detected by the horizontal detection mechanism.

[0118] In this embodiment, when the first housing is in either the first or second position relative to the second housing, the control mechanism receives a detection signal and makes a judgment: when the detection result meets the condition corresponding to the first detection signal, the control mechanism drives the indicator mechanism to output a first display signal; when the detection result meets the condition corresponding to the second detection signal, the control mechanism drives the indicator mechanism to output a second display signal. The operator can then identify the current deflection state and, by adjusting the grip posture, body angle, or cutting posture, bring the cutting plane back to the target range, thereby completing stable trimming.

[0119] By introducing a horizontal detection mechanism to detect the deflection state of the cutting plane, and having the control mechanism drive the indicator mechanism to output different display signals based on different detection signals, the "deflection state" can be intuitively fed back to the operator in real time, reducing errors and lags caused by experience-based judgment. Furthermore, this display logic can be executed in either the first or second position, ensuring consistent and reliable prompts even when the trimming tool's posture changes or the relative position of the housing (first housing relative to second housing). This allows the operator to promptly correct the cutting plane's posture, reducing the probability of accidental cutting and dangerous operations, improving operational safety, trimming accuracy, and efficiency, while also enhancing usability and ergonomics under different working conditions.

[0120] According to an eighth aspect of the present invention, a trimming tool is provided, the trimming tool comprising: The housing has a first housing with a first handle and a second housing with a second handle, the first housing being movable relative to the second housing between a first position and a second position; A cutting mechanism is mounted on the housing and has a cutting plane. An indicating mechanism, disposed on the housing, is configured to indicate the deflection state of the cutting plane relative to a reference plane; and The control mechanism, located on the housing, is configured to control the indication mechanism based on the deflection state of the cutting plane relative to the reference plane when the first housing is in either the first position or the second position relative to the second housing.

[0121] In this embodiment, during use, the operator holds the first handle and the second handle, and moves the first housing relative to the second housing between a first position and a second position according to the working posture requirements (e.g., switching the grip angle or the relative posture of the machine body). The cutting mechanism operates under drive and forms a corresponding cutting plane; the control mechanism acquires the deflection state of the cutting plane relative to the reference plane, and controls the indicating mechanism to output corresponding indication information when the first housing is in either the first position or the second position relative to the second housing, so that the operator can judge the deflection and adjust the trimming posture in real time based on the indication information.

[0122] By making the control mechanism's control of the indicating mechanism based on the deflection state of the cutting plane relative to the reference plane, and independent of the movement position of the first housing relative to the second housing (including whether rotation or attitude switching occurs), it avoids prompt failure, display misalignment, or inconsistent indication logic caused by changes in the relative position of the machine body. This ensures that the indicating mechanism can display the deflection state normally and continuously regardless of the position of the first housing relative to the second housing. This improves the reliability and consistency of the deflection prompt, allows the operator to promptly correct the cutting plane during attitude switching, reduces the risk of misjudgment and incorrect cutting, improves trimming safety and work efficiency, and enhances ergonomic adaptability under different working conditions. This application has the following beneficial effects: 1. By setting a protective plate on the housing and arranging the indicating mechanism in the front area of ​​the housing between the protective plate or the two handles (first handle and second handle), the indicating mechanism and the cutting plane are in the same forward field of view. In conjunction with defining the straight line extending along the length of the cutting plane and parallel to the reference plane as the deflection axis, the reference system for the deflection of the cutting plane is unified in terms of both structure and geometry. This allows the direction and degree of deflection of the cutting plane relative to the reference plane to be displayed intuitively in front of the operator, reducing the need for frequent looking down or looking back, and improving the continuity and safety of the trimming operation.

[0123] 2. By setting up a horizontal detection mechanism and clearly defining the reference plane as the first reference plane and / or the second reference plane corresponding to the states where the cutting plane is parallel to the horizontal plane and perpendicular to the horizontal plane, the judgment of the cutting plane deflection is established on a unified spatial reference. The horizontal detection mechanism detects the deflection state of the cutting plane relative to the reference plane in real time and outputs a detection signal. The control mechanism drives the indicator mechanism to display based on the detection signal. This can transform the attitude judgment that originally relied on experience and visual estimation into objective sensor detection and visual prompts, reducing the trimming error caused by differences in operating experience, lighting conditions and working conditions.

[0124] 3. By setting a first handle and a second handle distributed front and rear on the housing, and defining the range of geometric parameters such as the first included angle between the display surface of the indicator mechanism and the cutting plane, the tilt angle of the first handle relative to the reference plane, the second included angle between the preset plane and the cutting plane, the third included angle between the first handle and the line connecting the top of the protective plate, and the fourth included angle laterally, while also constraining the proportional relationship between the width of the second handle and the width of the indicator mechanism, a coordinated ergonomic layout is achieved between the grip position, the indicator position, and the cutting area. The aforementioned angle and distance parameters are not arbitrarily chosen, but rather optimized results determined after comprehensively considering grip comfort, field of vision, protection requirements, and center of gravity stability. This ensures stable tool operation while placing the indicator information in an easily obstructed position, thereby improving the ergonomics of the trimming process.

[0125] 4. By setting the first and second leads, the signal link between the horizontal detection mechanism, the control mechanism and the lamp board arranged in the middle or side area of ​​the protective plate is segmented. This ensures that the transmission path of the deflection signal and the display signal is clear and the anti-interference is strong. It also makes the installation position of the lamp board flexible and adjustable, which makes it easy to reuse the same detection and control module on different models and different protective plate structures, reducing wiring complexity and manufacturing costs.

[0126] 5. By designing the indicator mechanism as at least one or more light panels and setting multiple groups of LED beads on the light panels, and combining the brightness, position and / or color changes of the LED beads to provide graded indication of different deflection directions and different deflection angle ranges, more posture information can be carried within a limited display area. This allows the operator to quickly and accurately identify the deflection state of the current cutting plane in a short time, thereby making targeted adjustments to the posture of the trimming tool and improving the straightness and height consistency of the trimming lines.

[0127] 6. A rotatable connection is provided between the first housing and the second housing, and a sensing mechanism is provided at the pivot point between them to acquire the relative rotation information of the first housing or the second housing and output a rotation signal; based on the rotation signal, the control mechanism drives the indicator mechanism arranged in the corresponding area of ​​the first handle and / or the second handle to perform regional display, so that the rotational attitude of the first housing and the deflection state of the cutting plane about the deflection axis relative to the reference plane form a clear correspondence. Compared with the scheme of setting the detection element only at a fixed position on the housing, this disclosure uses the operator's actual grip posture at the second handle as a reference quantity for deflection judgment. Without increasing the structural complexity of the cutting mechanism, dynamic monitoring and visual feedback of the cutting plane attitude are achieved, which makes it convenient for the operator to finely control the cutting plane by finely adjusting the rotation angle of the first housing while maintaining a stable grip on the second handle.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0143] Although relative terms such as "up" and "down" are used in this invention to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as the orientation of the examples shown in the accompanying drawings. It is understood that if the icon's arrangement is flipped so that it is upside down, the component described as "up" will become the component described as "down". Other relative terms such as "high", "low", "top", "bottom", "front", "back", "left", and "right" also have similar meanings. When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0145] To address the problem that existing trimming tools cannot detect the deflection of the blade's cutting plane, this invention provides a trimming tool.

[0146] The technical solution provided in Embodiment 1 of the present invention is as follows: See Figure 1 , Figure 2 and Figure 3 A trimming tool includes a housing 1, a cutting mechanism 2, a driving mechanism 3, and an indicating mechanism 4. The housing 1 has a protective plate 11. The cutting mechanism 2 and the driving mechanism 3 are both located on the housing 1. The cutting mechanism 2 has a cutting plane S0, and the driving mechanism 3 is configured to drive the cutting mechanism 2 to operate. The indicating mechanism 4 is located on the protective plate 11 and is configured to indicate the deflection state of the cutting plane S0 relative to a reference plane. The deflection axis is a straight line extending along the length of the cutting plane S0 and parallel to the reference plane. The deflection state is the state in which the cutting plane S0 deflects relative to the reference plane around the deflection axis.

[0147] Pruning tools include, but are not limited to, pruning machines, lawn mowers, and other tools with cutting functions. Among them, pruning machines include, but are not limited to, pruning machines that move back and forth along the length of the tool, or pruning machines that move left and right along the width of the tool. The cutting plane S0 is the cutting motion plane formed when the cutting mechanism 2 performs the cutting action.

[0148] Furthermore, the cutting plane S0 is the cutting motion plane defined by the movement of the cutting edge of the cutting mechanism when performing the cutting action, that is, the working plane that cuts the target branch during the pruning process. Furthermore, in some embodiments, the cutting mechanism usually has a first side and a second side (e.g., an upper blade surface and a lower blade surface) arranged opposite to each other, and the cutting plane S0 refers to the geometric plane formed by the cutting edge against the object being cut during actual cutting, rather than any structural surface of the cutting mechanism body.

[0149] In this embodiment, a protective plate 11 is disposed on the housing 1, located on the side of the cutting mechanism 2 closest to the operator, at least partially between the cutting plane S0 and the operator. During the operation of the cutting mechanism 2, the protective plate 11 serves to block debris, dust, and foreign objects ejected by the cutting mechanism 2, reducing the possibility of foreign objects directly hitting the operator or the tool, thus providing safety protection. An indicating mechanism 4 is mounted on the protective plate 11, ensuring a defined relative positional relationship between the indicating mechanism 4 and the cutting plane S0. When the cutting plane S0 deflects relative to the reference plane around the deflection axis, the indicating mechanism 4 can provide a visual indication of the deflection state based on a pre-calibrated geometric relationship. With the indicating mechanism 4 positioned on the protective plate 11, it is within the operator's normal field of vision. The operator can directly observe the indication results while holding the trimming tool normally, without significantly changing their operating posture, facilitating timely and accurate adjustment of the trimming tool's orientation.

[0150] Through the above structural configuration, on the one hand, the protective plate 11 serves both to provide physical protection for the operator and as the mounting carrier for the indicating mechanism 4, integrating the protective function and the status indication function into one, reducing additional supports or exposed parts, and making the structure more compact; on the other hand, using a straight line extending along the length direction of the cutting plane S0 and parallel to the reference plane as the deflection axis, the deflection of the cutting plane S0 relative to the reference plane is limited to a single degree of freedom deflection around this deflection axis, which facilitates detection, calibration, and display through the indicating mechanism 4. Therefore, the trimming tool in this embodiment can provide real-time and intuitive feedback to the operator on the deflection status of the cutting plane S0 while ensuring operational safety, allowing the operator to adjust the trimming tool according to the instructions.

[0151] In some embodiments, when the indicating mechanism 4 is mounted on the protective plate 11, the protective plate 11 can adopt different structural forms to adapt to different installation methods and protection requirements. The protective plate 11 can be a single-layer structure or a double-layer structure.

[0152] In some embodiments, the protective plate 11 is a single-layer structure, which can be integrally formed from a metal sheet or an engineering plastic sheet, with the side facing the operator forming a mounting surface for installing the indicator mechanism 4. The indicator mechanism 4 can be directly fixed to the mounting surface by means of screw connection, snap connection, or adhesive bonding. The lead wire connected to the indicator mechanism 4 is led through a wire hole provided on the protective plate 11 or directly from the indicator mechanism 4 to the inside of the housing 1. The single-layer structure of the protective plate 11 is simple in structure, has low manufacturing cost, is easy to process and assemble, and is suitable for occasions where the installation space requirement for the indicator mechanism 4 is small.

[0153] In other embodiments, the protective plate 11 has a double-layer structure, comprising a first protective layer 111 and a second protective layer 112 arranged sequentially along the front-back direction of the trimming tool. The first protective layer 111 faces the cutting mechanism 2, and the second protective layer 112 faces the operator. The first protective layer 111 and the second protective layer 112 are spaced apart, forming a receiving space between them for accommodating the indicating mechanism 4. The indicating mechanism 4 is at least partially disposed within the receiving space. The display surface S3 of the indicating mechanism 4 communicates with the outside through a window penetrating the second protective layer 112 for operator observation; alternatively, the display surface S3 of the indicating mechanism 4 communicates with the outside through a window between the first protective layer 111 and the second protective layer 112 for operator observation. The electrical connection leads of the indicating mechanism 4 are routed within the receiving space and led out of the double-layer protective plate to the interior of the housing 1. The double-layer protective plate 11 can reserve installation space for the indicator mechanism 4 without significantly increasing the overall size of the trimming tool. On the other hand, the first protective layer 111 blocks the debris that splashes during the cutting process, and the double-layer structure covers and protects the indicator mechanism 4 and its lead wire, thereby improving the protective performance and installation stability of the indicator mechanism 4.

[0154] It should be noted that the drive mechanism 3 and the cutting mechanism 2 can adopt various existing structural forms known to those skilled in the art, such as a cutting assembly consisting of a motor, a transmission component and a cutting blade, or a cutting assembly driven by an internal combustion engine, etc., which do not constitute a limitation of this embodiment, and therefore will not be described in detail.

[0155] In some embodiments of this disclosure, see Figure 1 , Figure 3 The trimming tool is also equipped with a horizontal detection mechanism 5 (located inside the housing 1) and a control mechanism 8; the horizontal detection mechanism 5 is electrically connected to the indicating mechanism 4 and is configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal; the control mechanism 8 is configured to control the working state of the indicating mechanism 4 based on the detection signal; wherein, the reference plane includes a first reference plane S1 and / or a second reference plane S2 (see Figure 5The first reference plane S1 is the plane where the cutting plane S0 is parallel to the horizontal plane; the second reference plane S2 is the plane where the cutting plane S0 is perpendicular to the horizontal plane. In this way, the horizontal detection mechanism 5 can monitor the deflection state of the cutting plane S0 relative to the reference planes in real time (e.g., including precise deflection angle and direction). This information is directly presented to the operator through the control mechanism 8 and the control indicator mechanism 4, helping the operator to adjust the posture of the trimming tool in real time and ensuring the accuracy of the cutting operation.

[0156] In some exemplary embodiments, the level detection mechanism 5 may not be limited to a gyroscope or a level, but may include, for example, a microelectromechanical system (MEMS) gyroscope. The gyroscope is installed at a position that has a defined geometric relationship with the cutting plane S0, and is used to sense the attitude change of the trimming tool in space and output a detection signal corresponding to the attitude change.

[0157] In some embodiments of this disclosure, the indicating mechanism 4 includes a set of light panels 41; the light panels 41 are disposed on the protective plate 11.

[0158] As an example, the light panel 41 is mounted on the protective plate 11 and is located within the operator's field of vision. The light panel 41 has a defined relative positional relationship with the cutting plane S0, and is used to indicate the deflection state of the cutting plane S0 relative to the reference plane through the display state of the light panel 41. For example, the surface of the light panel 41 can be set at an angle to or parallel to the cutting plane S0, with the light panel 41 facing the operator. When the deflection state of the cutting plane S0 relative to the reference plane changes, the control mechanism 8 can control the display pattern and / or display area of ​​the light panel 41 to change, thereby intuitively reflecting the deflection direction and degree of the cutting plane S0, facilitating the operator to adjust the posture of the trimming tool while observing the display on the light panel 41.

[0159] In some embodiments of this disclosure, the indicating mechanism 4 includes at least two sets of light panels 41; at least two sets of light panels 41 are disposed on the protective plate 11, and a predetermined angle is formed between the projections of any two sets of light panels 41 on the plane of the protective plate 11.

[0160] In one embodiment of this disclosure, the indicating mechanism 4 may include at least three sets of light panels 41, all of which are disposed on the protective plate 11, and any two sets of light panels 41 form a predetermined angle between their projections on the plane of the protective plate 11.

[0161] As an example, one set of light panels 41 can be arranged with their surfaces generally horizontal as horizontal light panels 41; another set of light panels 41 can be arranged with their surfaces generally vertical as vertical light panels 41. The vertical light panels 41 can be arranged to the left or right of the horizontal light panels 41, so that the projections of the horizontal light panels 41 and the vertical light panels 41 onto the plane of the protective plate 11 form an angle. With this arrangement, the horizontal light panels 41 can be used to indicate the overall horizontal attitude of the cutting plane S0 relative to the reference plane, and the vertical light panels 41 can be used to emphasize the deflection trend on one side. When a richer indication effect is needed, another set of vertical light panels 41 can be reserved or added on the side opposite to the vertical light panels 41 to form an arrangement of at least three sets of light panels 41, thereby taking into account the needs of structural simplification and functional expansion without changing the predetermined angle design.

[0162] As another example, one set of light panels 41 is arranged substantially horizontally, while the other two sets of light panels 41 are arranged substantially vertically on the left and right sides of the horizontal light panel 41, such that a first predetermined angle (e.g., approximately 90°) is formed between the projection of any vertical light panel 41 and the horizontal light panel 41 onto the plane of the protective plate 11, and a second predetermined angle (e.g., approximately 90°) is formed between the projections of the two sets of vertical light panels 41 onto the plane of the protective plate 11. In this embodiment, the horizontal light panel 41 can indicate whether the cutting plane S0 is within the target horizontal neutral range relative to the reference plane; the left and right vertical light panels 41 can be used to indicate the deflection position and degree of the cutting plane S0 to the left or right, respectively, thereby achieving a visual distinction between the deflection direction and amount.

[0163] In addition, in this embodiment, the horizontal light panel 41 can also indicate whether the cutting plane S0 is within the target neutral range relative to the reference plane and the deflection position and degree of deflection to the left or right; the left and right light panels can also indicate whether the other reference plane is within the target horizontal neutral range and the deflection position and degree of deflection to the left or right.

[0164] Specifically, in this embodiment, the horizontal light panel 41 located in the middle of the protective plate 11 can be used to indicate whether the cutting plane S0 is within the target horizontal neutral range relative to the first reference plane S1. The light panel 41 can also indicate the direction and degree of deflection of the cutting plane S0 to the left or right by the combination of on / off states, position distribution, and / or brightness changes of the LED bead group 411 on the light panel 41. The horizontal light panel 41 located in the middle of the protective plate 11 can also simultaneously indicate whether the cutting plane S0 is within the target horizontal neutral range relative to both the first reference plane S1 and the second reference plane S2. The light panel 41 can also indicate the neutral position, the direction and degree of deflection of the cutting plane S0 to the left or right by the combination of on / off states, position distribution, and / or brightness changes of the LED bead group 411 on the horizontal light panel 41.

[0165] The lamp panels 41, which are set on the left and right sides of the horizontal lamp panel 41, can correspond to the left side of the second reference plane S2 and the right side of the second reference plane S2, respectively. They are used to indicate whether the direction of the cutting plane S0 relative to its corresponding reference plane is within the horizontal neutral range of the target reference plane and the deflection position and angle to the left or right. On the same lamp panel 41, the greater the distance of the lit lamp bead group 411 from the center reference position of the lamp panel and / or the higher the brightness, the greater the deflection angle of the corresponding cutting plane S0 relative to the corresponding reference plane (first reference plane S1 or second reference plane S2).

[0166] For example, in one exemplary configuration, the light panel 41 on the left side of the protective plate 11 can be used to indicate the deflection state of the cutting plane S0 relative to the left direction of the second reference plane S2, and the light panel 41 on the right side of the protective plate 11 can be used to indicate the deflection state of the cutting plane S0 relative to the right direction of the second reference plane S2: when the cutting plane S0 deflects to the left relative to the left direction of the second reference plane S2, the LED group 411 on the left side of the left light panel 41 is lit or lit at a higher brightness; when the cutting plane S0 returns to the horizontal neutral range of the target reference plane near the second reference plane S2, the LED group 411 in the middle of the left light panel 41 is constantly lit or displayed in a predetermined color; when the cutting plane S0 deflects to the right direction of the second reference plane S2, it is indicated by LED groups 411 at different positions, with different brightness and / or different colors on the right light panel 41. Of course, in another example, the left light panel 41 can be configured to display the deflection state of the cutting plane S0 relative to the second reference plane S2, and the right light panel 41 can be configured to display the deflection state of the cutting plane S0 relative to the first reference plane S1. The deflection information corresponding to the first reference plane S1 and the second reference plane S2 can be distinguished by the difference in color, brightness and / or flashing mode of the LED bead group 411, so as to adapt to different product designs and user habits.

[0167] In another example, the right light panel 41 can be configured to display the deflection state of the cutting plane S0 relative to the second reference plane S2, and the left light panel 41 can be configured to display the deflection state of the cutting plane S0 relative to the first reference plane S1. The deflection information corresponding to the first reference plane S1 and the second reference plane S2 can be distinguished by the differences in the color, brightness, and / or flashing mode of the LED bead group 411, in order to adapt to different product designs and user habits. Of course, in another example, the horizontal light panel 41 located in the middle of the protective plate 11 can also be used to indicate whether the cutting plane S0 is in the target horizontal neutral range relative to the first reference plane S1 and the second reference plane S2. When the cutting plane S0 is in the neutral range relative to the first reference plane S1, the LED beads 411 in the middle of the horizontal light panel 41 are bright. When it deflects to the left relative to the first reference plane S1, the LED bead group 411 facing the left in the middle of the horizontal light panel 41 is lit or lit at a higher brightness. When the horizontal light panel 41 is deflected to the right relative to the first reference plane S1, the LED group 411 facing right in the middle of the horizontal light panel 41 is lit or lit at a higher brightness. When the cutting plane S0 is in the horizontal neutral range of the target reference plane near the second reference plane S2, the LED group 411 on the left side of the horizontal light panel 41 is constantly lit or displayed in a predetermined color. At this time, the leftmost LED serves as the display LED of the horizontal neutral range. Based on this display LED, there are LEDs on the left and right sides that can display the leftward or rightward deflection of the cutting plane in the left direction of the second reference plane. When the cutting plane S0 is deflected to the right side relative to the second reference plane S2, the LED group 411 on the right side of the horizontal light panel 41 is constantly lit or displayed in a predetermined color. At this time, the rightmost LED serves as the display LED of the neutral range. Based on this display LED, there are corresponding LEDs on the left and right sides that can display the leftward or rightward deflection of the cutting plane in the right direction of the second reference plane.

[0168] As another example, the surfaces of the two sets of light panels 41 are respectively arranged on the left and right sides of the protective plate 11, and are symmetrically inclined relative to the vertical direction. This causes the projections of the two sets of light panels 41 onto the plane of the protective plate 11 to form an angle relationship similar to the figure eight. That is, the projections of the two sets of light panels 41 onto the plane of the protective plate 11 diverge upwards or downwards from each other, forming a third predetermined angle. The beneficial effects of this figure eight arrangement are: on the one hand, the inclined light panels 41 on both sides can visually create a natural convergence or divergence guide, making it easier for the operator to distinguish the direction and degree of deflection; on the other hand, compared with a completely vertical arrangement, the inclined arrangement can optimize the observation angle according to the grip posture, reduce the deflection of the line of sight, and improve the comfort of long-term operation.

[0169] It should be noted that, in addition to the above-mentioned figure-eight arrangement, the combined shape of the light panel 41 can also be a "V" shape, an inverted "V" shape, a "U" shape, a "door" shape, or other polygonal or arc-shaped arrangements. As long as the projections of different light panels 41 on the plane of the protective plate 11 form a predetermined angle and can provide a direct indication of the deflection state of the cutting plane S0, they can be selected and designed according to actual needs. This disclosure is not limited to the above-mentioned specific forms.

[0170] It should be further noted that in this disclosure, the determination of directional terms such as left and right is based on the user's usage state: when the user normally holds the handle of the trimming tool and the cutting plane S0 faces the user in front to perform the trimming operation, the left side of the user's left hand corresponds to the left side of the trimming tool, and the right side of the user's right hand corresponds to the right side of the trimming tool; the above directional terms are only used to facilitate the explanation of the relative positional relationship between the components and do not constitute a limitation on the scope of protection of this disclosure.

[0171] In some embodiments of this disclosure, see Figure 2 The indicating mechanism 4 includes at least two sets of light panels 41. These at least two sets of light panels 41 are mounted on the protective plate 11, and their projections on the plane of the protective plate 11 are parallel to each other. By mounting at least two sets of light panels 41 on the protective plate 11 and ensuring their projections on the plane of the protective plate 11 are parallel to each other, on the one hand, the light panels 41 can be arranged along the same reference direction, unifying the reading direction of the indicating information. The operator only needs to observe the changes in different light panels 41 or different display areas on the same light panel 41 in a single direction to determine the deflection of the cutting plane S0 relative to the reference plane, reducing the visual recognition burden and improving the intuitiveness and readability of the indicating information. On the other hand, the parallel arrangement of the two sets of light panels 41 makes the overall layout of the indicating mechanism 4 on the protective plate 11 more regular, facilitating unified wiring planning and enabling subsequent additions or deletions of the number of light panels 41 to achieve functional expansion. Simultaneously, it reduces mutual obstruction between the light panels 41, improving the compactness and aesthetics of the structural layout, thus ensuring the indicating function while also considering manufacturing and assembly convenience and product appearance consistency.

[0172] In some embodiments of this disclosure, the indicating mechanism 4 includes at least two sets of lamp panels 41; wherein, in two adjacent sets of lamp panels 41, the output terminal of one set of lamp panels 41 is sequentially electrically connected to the input terminal of the other set of lamp panels 41. By sequentially connecting the output terminal of one set of lamp panels 41 to the input terminal of the other set of lamp panels 41 in two adjacent sets of lamp panels 41, a series or cascaded relationship is formed. On the one hand, multiple sets of lamp panels 41 can be driven to work sequentially by the same control channel, reducing the number of independent connections between the lamp panels 41 and the control mechanism 8, as well as the number of control ports, thereby reducing the complexity of circuit wiring and the cost of control circuit.

[0173] In some embodiments of this disclosure, see Figure 1 , Figure 3 The housing 1 is provided with a first handle 12 and a second handle 13; the first handle 12 is located at one end of the housing 1 near the cutting mechanism 2 and the protective plate 11; the second handle 13 is located at one end of the housing 1 away from the cutting mechanism 2 and the protective plate 11; the display surface S3 of the indicator mechanism 4 forms a first included angle R1 with the cutting plane S0; wherein the first included angle R1 is greater than or equal to 20° and less than 90°.

[0174] With the above arrangement, when the operator holds the first handle 12 and the second handle 13, the end near the cutting mechanism 2 can be accurately guided and stably supported, while the handle away from the cutting mechanism 2 can enhance the overall operational stability and reduce the shaking and deviation caused by single-handed gripping. At the same time, the display surface S3 of the indicator mechanism 4 forms a first angle R1 with respect to the cutting plane S0, so that the indicator information is tilted towards the operator's line of sight. This allows the operator to intuitively obtain the deflection information of the cutting plane S0 relative to the reference plane while maintaining a safe standing position and normal gripping posture, thereby improving the safety and accuracy of the trimming operation and reducing visual fatigue and wrist burden during long-term operation.

[0175] In some specific embodiments, the first included angle R1 can be optimized according to the usage scenario and the operator's height and grip posture. For example, the first included angle R1 can be 20° to 30° to suit trimming conditions that require close proximity to the workpiece and have a low line of sight; in other embodiments, the first included angle R1 can be 30° to 60°, so that the display surface S3 has a more obvious elevation angle relative to the cutting plane S0, making it easier for the operator to observe the indication information from above in a standing posture; as another example, in a further embodiment, the first included angle R1 can be 60° to 80° so that the display information of the indicating mechanism 4 can still be clearly read when a large safety distance needs to be maintained or when the tool is used in an inclined posture.

[0176] It should be understood that the specific value of the first included angle R1 is not limited to the typical angles within the range of the examples mentioned above. As long as the first included angle R1 falls within the range of greater than or equal to 20° and less than 90°, and can ensure that the display surface S3 of the indicator mechanism 4 is not obstructed by the protective plate 11, the handle, or the operator's hand, allowing the operator to conveniently observe the indicator information in a normal holding posture, it can be considered to fall within the protection scope of this application. In other embodiments, the first included angle R1 can be a fixed angle, or it can be adjusted within a preset range through an adjustable structure to adapt to different cutting postures and usage environments, thereby further improving the versatility and comfort of the trimming tool.

[0177] Furthermore, in this embodiment, when the first included angle R1 is less than 20°, the display surface S3 is too close to the cutting plane S0, and the display surface S3 is easily obstructed by the blade, protective plate 11, or pruned plants. The user also needs to observe the indicator information within a very small viewing angle, increasing the difficulty of recognition. When the first included angle R1 is greater than 90°, the display surface S3 tends to face away from the user or is too vertical. The user needs to significantly twist their wrist or look up sharply to see the indicator information, which can easily lead to operational fatigue and increase safety hazards. Therefore, limiting the first included angle R1 to the range of 20° to 90° allows the display surface S3 to avoid obstruction while still being clearly visible in a natural grip posture, achieving a reasonable balance between visibility, obstruction relationship, and grip comfort. This parameter range is specifically determined to achieve the aforementioned comprehensive technical effect and is not a conventional adaptive modification by adjusting the angle of the display surface S3 to cater to appearance or installation convenience.

[0178] It should be noted that "the display surface S3 of the indicator mechanism 4" here refers to the geometric plane of the visible area of ​​the indicator mechanism 4 used to display light signals and / or graphic and text information to the operator when it is installed. Specifically, when the indicator mechanism 4 includes a lamp panel 41 and multiple LEDs disposed on the lamp panel 41, the display surface S3 is the panel surface of the lamp panel 41 facing the operator; when the indicator mechanism 4 also includes a light-transmitting cover, the display surface S3 can be the geometric plane corresponding to the area of ​​the light-transmitting cover facing the operator used to display indicator information.

[0179] In other embodiments of this disclosure, see Figure 5 The reference plane (second reference plane S2) perpendicular to the cutting plane S0 forms an inclined angle R5 with the cross-section extending along the length of the first handle 12, with the inclined angle R5 ranging from 0° to 15°. By slightly tilting the first handle 12 within this range, the forearm and wrist joint are closer to a neutral position when the operator is in a normal grip posture, which can reduce the twisting and flexion range of the wrist joint and reduce the continuous force on the wrist and forearm muscles. At the same time, it is beneficial for the operator to form a stable force triangle when gripping with both hands, improving the guidance and controllability of the trimming tool, thereby improving ergonomics and reducing fatigue during long-term operation while ensuring cutting accuracy.

[0180] For example, the first handle 12 forms an inclined angle R5 relative to the reference plane (second reference plane S2) perpendicular to the cutting plane S0; the inclined angle R5 can be 0° to 5°, in which case the first handle 12 is basically arranged to be perpendicular to the cutting plane S0, which is more suitable for rough trimming conditions that require a large pushing and pulling force; in other embodiments, the inclined angle R5 can be 5° to 10°, and the first handle 12 has a moderate degree of inclination relative to the reference plane, which is beneficial to reduce the lateral deviation of the wrist joint while taking into account the smoothness of the pushing and pulling force path; as another example, in a further embodiment, the inclined angle R5 can be 10° to 15°, which is more suitable for usage scenarios that are mainly for fine guidance and light pressure trimming, and facilitates the operator to make fine adjustments while ensuring grip stability.

[0181] It should be noted that when the tilt angle R5 of the first handle 12 is less than 0°, that is, when the first handle 12 is tilted away from the operator relative to the reference plane, it is easy to cause the operator's wrist joint to deflect and twist in an unfavorable direction, resulting in an unnatural grip posture and making it unsuitable for long-term continuous work. When the tilt angle R5 of the first handle 12 is greater than 15°, the first handle 12 is tilted excessively towards the operator, which will increase the forearm rotation angle and shoulder elevation range, thereby increasing muscle tension and potentially reducing stability during high-thrust operations. This application limits the tilt angle R5 of the first handle 12 to the range of 0° to 15°, which is a balanced choice obtained after comprehensively considering the operator's ergonomic characteristics, typical working posture, and the stability of the trimming tool operation, taking into account both grip comfort and operational safety and controllability.

[0182] In some embodiments of this disclosure, see Figure 4 The indicator mechanism 4 is positioned near the bottom of the housing 1 and the top of the grip portion 121 of the first handle 12, forming a preset plane S4. The preset plane S4 and the cutting plane S0 are set at a second angle R2, which is between 0° and 90°. This arrangement constrains the relative height and spatial relationship between the indicator mechanism 4 and the first handle 12 in the longitudinal direction of the tool. This makes it easier for the operator's line of sight to fall on the area where the indicator mechanism 4 is located when holding the first handle 12 normally. Thus, without significantly changing the existing grip posture, the operator can intuitively perceive the deflection state of the cutting plane S0 relative to the reference plane. Simultaneously, by limiting the angle range between the preset plane S4 and the cutting plane S0, it is beneficial to ensure the visibility of the indicator information while also considering the compactness of the overall structure and the arrangement space of the internal components of the housing 1, thereby improving the ergonomics and structural utilization of the entire machine.

[0183] For example, the second included angle R2 can be 0° to 30°. In this case, the preset plane S4 is basically parallel to the cutting plane S0, which is suitable for scenarios where the tool is in a low posture and close to the workpiece surface for push-pull trimming. The operator can see the indication information by slightly lowering their head. In other embodiments, the second included angle R2 can be 30° to 60°. The preset plane S4 has a medium tilt angle relative to the cutting plane S0, which is suitable for most conventional standing postures. It can maintain a good viewing angle while ensuring stable support for the tool in the front and back directions. In a further embodiment, the second included angle R2 can be 60° to 90°. In this case, the preset plane S4 is almost perpendicular to the cutting plane S0, which is more conducive to clearly identifying the display information of the indicator mechanism 4 when the operator maintains a large safe distance and observes the tool from the side and above.

[0184] It should be noted that when the second included angle R2 is too small, close to 0°, the preset plane S4 and the cutting plane S0 almost coincide. The distance between the indicator mechanism 4 and the first handle 12 in terms of height and front-back direction is insufficient, making it easy for the plant being pruned or the user's hand to block the view. It also makes it difficult to reserve sufficient installation space and visibility space for the indicator mechanism 4. When the second included angle R2 is too large, close to or exceeding 90°, the preset plane S4 is raised too high relative to the cutting plane S0. The height difference and front-back offset of the indicator mechanism 4 relative to the first handle 12 are too large. This will not only raise the front center of gravity and reduce the stability of the whole machine during the pruning process, but may also obstruct the user's observation of the environment in front and the cutting area. Therefore, limiting the second included angle R2 to the range of 0° to 90° can ensure that the indicator mechanism 4 has an appropriate height difference and visibility space, while avoiding an excessively high center of gravity and limited field of vision. A reasonable balance is achieved between the field of vision, the obstruction relationship and the stability of the whole machine. This parameter range is specifically set to achieve the above comprehensive technical effect, and is not a simple adaptive adjustment made for appearance design or assembly convenience.

[0185] In some embodiments of this disclosure, see Figure 5 The plane containing the line connecting the top of the first handle 12 and the top of the protective plate 11 forms a third angle R3 with the horizontal plane containing the top of the first handle 12; wherein the third angle R3 is between 10° and 45°. By limiting this third angle R3, the height and front-back position of the protective plate 11 relative to the first handle 12 can be reasonably determined in space, so that the protective plate 11 provides shielding and protection for the operator without excessively raising or lowering its top position, thereby reducing obstruction of the operator's line of sight; at the same time, the top of the protective plate 11 forms a certain angle of elevation with the top of the first handle 12, which is beneficial to block flying debris and rebounding objects outside the safe area during trimming, and combined with the ergonomic grip height and line of sight direction, improves the safety and comfort of tool use.

[0186] For example, the third included angle R3 can be 10° to 20°. In this case, the top of the protective plate 11 is slightly raised relative to the top of the first handle 12, which is suitable for working conditions where the main task is rough trimming by pushing and pulling and a large field of vision is required. In other embodiments, the third included angle R3 can be 20° to 30°. The top of the protective plate 11 has a moderate height difference and front-back position difference relative to the top of the first handle 12, which is more suitable for fine trimming operations in most conventional standing postures, ensuring both shielding effect and ease of observation. In yet another embodiment, the third included angle R3 can be 30° to 45°. The top of the protective plate 11 is raised more significantly relative to the top of the first handle 12, which is more conducive to use in scenarios with more flying debris or where a greater safety margin is required, thereby improving the protection of the operator's face and upper limbs.

[0187] Specifically, when the third included angle R3 is less than 10°, the height difference between the top of the first handle 12 and the top of the protective plate 11 is small, and the protective plate 11 is too close to the top of the first handle 12. The indicating mechanism 4 is difficult to form a significant protrusion effect in the height direction. During the trimming process, it is easily blocked by the user's hand, arm or the plant in front, which is not conducive to the timely and clear identification of the indicating information. At the same time, the blocking effect of the protective plate 11 on flying debris is also relatively weakened. When the third included angle R3 is greater than 45°, the protective plate 11 is raised too high relative to the top of the first handle 12, which makes the front end structure protrude significantly in the vertical direction. This will not only raise the center of gravity of the front end and affect the stability of the trimming tool when swinging back and forth, but may also block the user's view of the environment and cutting area in front, increasing the inconvenience of operation and safety hazards. Therefore, the value of the third included angle R3 is limited to between 10° and 45°, creating a suitable height difference between the protective plate 11 and the top of the first handle 12. This ensures that the indicating mechanism 4 is in a relatively prominent and visible position when the user holds the first handle 12, guaranteeing both the readability of the indicated information and the protection performance and overall stability of the machine. This included angle range is a parameter limitation determined based on a comprehensive consideration of protection performance, field of vision, and overall structural coordination, and is not a conventional adjustment made by simply raising or lowering the position of the protective plate 11 to adapt to the appearance of different models.

[0188] In some embodiments of this disclosure, see Figure 6The plane containing the line connecting the vertex of the side of the first handle 12 and the vertex of the side of the protective plate 11 forms a fourth included angle R4 with the reference plane (second reference plane S2) perpendicular to the cutting plane S0; wherein the angle of the fourth included angle R4 is between 0° and 35°. By limiting this fourth included angle R4, on the one hand, the relative height and offset relationship between the first handle 12 and the protective plate 11 on the lateral contour of the tool can be constrained, so that the protective plate 11 forms an effective lateral shielding area on the side of the tool to block debris that splashes laterally along the cutting plane S0; on the other hand, it avoids the side of the protective plate 11 from excessively extending outward or retracting relative to the side of the first handle 12, so that there will be no obvious lateral interference or squeezing when the operator holds the first handle 12 normally, thereby improving the lateral protection capability while taking into account the grip comfort and ergonomic characteristics.

[0189] For example, the fourth included angle R4 can be 0° to 10°. In this case, the plane connecting the side apex of the first handle 12 and the side apex of the protective plate 11 has only a small inclination relative to the cutting plane S0. This is suitable for working conditions where the lateral profile of the whole machine is relatively compact, which helps to reduce the space occupied by the tool in the side. In other embodiments, the fourth included angle R4 can be 10° to 25°. The side of the protective plate 11 forms a moderate inclination angle relative to the cutting plane S0, which not only ensures the effectiveness of lateral shielding, but also takes into account the visibility of the cutting area of ​​the operator at different standing angles, which is more suitable for most conventional trimming postures. Furthermore, in a further embodiment, the fourth included angle R4 can be 25° to 35°. The side of the protective plate 11 is more significantly inclinated relative to the cutting plane S0, which is more conducive to use in scenarios with more splashes or where it is necessary to increase the lateral safety margin of the tool, so as to enhance the protection of the operator's lateral body area.

[0190] Specifically, when the fourth included angle R4 is close to 0° or even close to 0°, the plane connecting the side apex of the first handle 12 and the side apex of the protective plate 11 is almost parallel to the cutting plane S0. The lateral offset of the protective plate 11 relative to the first handle 12 is small, and the indicator mechanism 4 is more easily obstructed by the user's hand, forearm, or the side of the housing 1, resulting in insufficient lateral visibility. The user may find it difficult to observe the indicator information in a timely manner under normal grip posture. When the fourth included angle R4 is greater than 35°, the lateral offset between the first handle 12 and the protective plate 11 is large. The protective plate 11 and the indicator mechanism 4 are significantly offset to one side, which can easily cause the trimming tool to generate a large deflection torque when subjected to lateral force. The stability of the whole machine decreases when it swings left and right or is suddenly subjected to lateral impact. At the same time, it may also cause the indicator mechanism 4 to deviate from the user's direct field of vision, which will affect the actual observation.

[0191] In some embodiments of this disclosure, see Figure 7On the projection plane perpendicular to the cutting plane S0, the widest distance of the projection of the first handle 12 is the first distance L1; the widest distance of the projection of the indicating mechanism 4 is the second distance L2; wherein, the value of the first distance L1 is between 190mm and 250mm; the value of the second distance L2 is between 100mm and 250mm, and the ratio between the first distance L1 and the second distance L2 is between 1:1 and 1:2.5. By limiting the maximum distance between the first handle 12 and the indicator mechanism 4 on the projection plane perpendicular to the cutting plane S0 within the aforementioned range, and by constraining the ratio between the two, it is possible to ensure that the first handle 12 has sufficient grip width, so that the operator can obtain stable support and appropriate force distribution when gripping with both hands. On the other hand, it ensures that the width of the indicator mechanism 4 on the projection plane matches that of the first handle 12, so that it is neither too narrow, resulting in an excessively small display area for indicator information and poor readability, nor too wide, occupying too much lateral space of the housing 1. This achieves a more reasonable balance between grip comfort, overall structural compactness, and visibility of indicator information.

[0192] For example, in some specific embodiments, the first distance L1 can be selected as approximately 200 mm, and the second distance L2 can be selected as approximately 200 mm. In this case, the ratio of the two is approximately 1:1, which is beneficial for forming a harmonious and integrated appearance on the side of the housing 1. In other embodiments, the first distance L1 can be approximately 220 mm, and the second distance L2 can be approximately 240 mm. In this case, the ratio is approximately 1:1.1, which helps to maintain a harmonious relationship with the width of the second handle 13 while slightly increasing the display width of the indicator mechanism 4. Furthermore, in a further embodiment, the first distance L1 can be approximately 190 mm, and the second distance L2 can be approximately 250 mm. In this case, the ratio is approximately 1:1.32, which gives the indicator mechanism 4 a larger display width to improve visibility in complex working conditions.

[0193] As an example, the housing 1 is provided with a first handle 12 and a second handle 13; the first handle 12 is located at one end of the housing 1 near the cutting mechanism 2 and the protective plate 11; the second handle 13 is located at one end of the housing 1 away from the cutting mechanism 2 and the protective plate 11; the display surface S3 of the indicating mechanism 4 forms a first angle R1 with the cutting plane S0; wherein the first angle R1 is greater than or equal to 20° and less than 90°; and / or, the tilt angle of the first handle 12 relative to the reference plane perpendicular to the cutting plane S0 is in the range of 0° to 15°; and / or, the bottom end of the indicating mechanism 4 near the housing 1 and the top end of the grip portion 121 of the first handle 12 form a preset plane S4, and the preset plane S4 and the cutting plane S0 form a second angle R2, the second angle R2 being between 0° and 90°; and / or, the top end of the first handle 12 and the protective plate 11 form a second angle R2 with the cutting plane S0. The plane containing the line connecting the tops of the guard plates 11 forms a third angle R3 with the horizontal plane containing the top of the first handle 12; wherein the third angle R3 is between 10° and 45°; and / or, the plane containing the line connecting the top of the side of the first handle 12 with the top of the side of the guard plate 11 forms a fourth angle R4 with the cutting plane S0; wherein the angle of the fourth angle R4 is between 0° and 35°; and / or, on the projection plane perpendicular to the cutting plane S0, the widest distance of the projection of the first handle 12 is the first distance L1; the widest distance of the projection of the indicating mechanism 4 is the second distance L2; wherein the value of the first distance L1 is between 190 and 250; the value of the second distance L2 is between 100 and 250, and the ratio between the first distance L1 and the second distance L2 is between 1:1 and 1:2.5.

[0194] In some embodiments of this disclosure, see Figure 3The trimming tool also includes a first lead 6 and a second lead 7. One end of the first lead 6 is electrically connected to the horizontal detection mechanism 5, and the first lead 6 is configured to transmit the deflection signal of the cutting plane S0 relative to the reference plane obtained by the horizontal detection mechanism 5. The control mechanism 8 is electrically connected to the other end of the first lead 6, and the control mechanism 8 is configured to output a display signal based on the deflection signal. One end of the second lead 7 is electrically connected to the control mechanism 8, and the other end of the second lead 7 extends to the middle area of ​​the protective plate 11 and is electrically connected to the input end of any set of lamp panels 41; or, the other end of the second lead 7 extends to the side area of ​​the protective plate 11 and is electrically connected to the input end of any set of lamp panels 41. The second lead 7 is configured to load the display signal onto the lamp panel 41. By using the above wiring method of the first lead 6 and the second lead 7, a reliable electrical connection between the horizontal detection mechanism 5, the control mechanism 8, and the lamp panels 41 on the protective plate 11 can be achieved while maintaining a compact structure. On the one hand, the first lead 6 directly transmits the deflection signal of the cutting plane S0 relative to the reference plane between the horizontal detection mechanism 5 and the control mechanism 8, and the signal path is clear; on the other hand, the second lead 7 is led out from the control mechanism 8 and extends to the middle or side area of ​​the protective plate 11, and is electrically connected to the input end of any set of lamp boards 41, so that the installation position of the lamp board 41 has a certain degree of freedom, which makes it easy to flexibly adjust the wiring path according to the layout of the internal components of the housing 1 and the structural form of the protective plate 11, shorten the cable length, avoid moving parts such as the cutting mechanism 2 and high interference areas, and improve the safety and anti-interference ability of the wiring.

[0195] Furthermore, the second lead 7 can preferably be arranged inside the housing 1 or the protective plate 11 to reduce cable exposure and reduce the risk of accidental snagging, wear or cutting, thereby improving the reliability, assembly convenience and ease of maintenance of the whole machine.

[0196] In some embodiments of this disclosure, the light panel 41 has multiple groups of LED beads 411; the working state of the indicator mechanism 4 includes the brightness and / or position of the LED bead groups 411, and / or the display color of the LED bead groups 411. By controlling the combination of brightness and off states, brightness levels, and color changes of different LED bead groups 411, various information such as the deflection direction of the cutting plane S0, the deflection angle, and whether it exceeds the preset safety range can be expressed within a limited display area, thereby improving the readability and information carrying capacity of the indicator mechanism 4.

[0197] Specifically, as an example, the brightness of different LEDs within LED group 411 can reflect the magnitude of the deflection angle of the cutting plane S0. For instance, an LED group 411 may include at least three LEDs: a first LED, a second LED, and a third LED. When the deflection angle of the cutting plane S0 is small, only the first LED is lit, and / or lit at a lower brightness, to indicate that the deflection is small and basically within a safe range. When the deflection angle of the cutting plane S0 further increases, the first and second LEDs are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED, to indicate that the deflection angle is in a medium range and requires adjustment by the operator. When the deflection angle of the cutting plane S0 increases to a large range, the first, second, and third LEDs are lit together, and / or the third LED is displayed in a high-brightness or flashing manner, to indicate that the deflection angle is large or even close to the upper limit of the allowable range, reminding the operator to adjust or stop the operation in time. It may also include the following: when the cutting plane S0 is not deflected, the first LED is lit; when the cutting plane S0 is deflected to the left, the second LED is lit, and the greater the deflection angle, the brighter the second LED is, or the color changes (e.g., from yellow to red); when the cutting plane S0 is deflected to the right, the third LED is lit, and the greater the deflection angle, the brighter the third LED is, or the color changes (e.g., from yellow to red). The first LED may also be either the second or third LED. It should be noted that the number of LEDs, the lighting order, and the brightness change method described above can be adjusted according to actual needs and do not constitute a limitation on the scope of protection of this disclosure.

[0198] As another example, the deflection angle of the cutting plane S0 can be reflected by the on / off position of different LEDs within the LED group 411. For instance, an LED group 411 may include at least three LEDs arranged sequentially along a preset direction, namely, a first LED, a second LED, and a third LED: when the deflection angle of the cutting plane S0 is small, only the first LED located near the preset reference position is lit, indicating that the deflection is small and basically within a safe range; when the deflection angle of the cutting plane S0 further increases, the first LED is turned off, and only the second LED located in the middle position is lit, indicating that the deflection angle is in a medium range and requires the operator to pay attention to adjustment; when the deflection angle of the cutting plane S0 increases to a large range, only the third LED located on the side away from the reference position is lit, and / or the third LED flashes, indicating that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the number of LEDs, their arrangement, and the lighting positions corresponding to different deflection angles can be adjusted according to actual needs. For example, two or more LEDs at different positions can be lit simultaneously to represent a more detailed deflection range, which does not limit the scope of protection of this disclosure.

[0199] As another example, the deflection angle of the cutting plane S0 can be reflected by the display color of the LEDs in the LED group 411. For example, an LED group 411 may include at least three LEDs, namely a first LED, a second LED, and a third LED: when the deflection angle of the cutting plane S0 is small, the first LED displays a first color, such as green, to indicate that the deflection is small and basically within a safe range; when the deflection angle of the cutting plane S0 further increases, the second LED displays a second color, such as yellow, to indicate that the deflection angle is in a medium range and requires adjustment by the operator; when the deflection angle of the cutting plane S0 increases to a large range, the third LED displays a third color, such as red, and / or displays in a flashing red manner to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the first color, the second color, and the third color are not limited to the above-mentioned examples of green, yellow, and red, and any color combination that is easily distinguishable from each other can be selected according to actual needs, and this does not limit the scope of protection of this disclosure.

[0200] The following description uses an indicator mechanism 4 consisting of only one light panel 41 as an example. The light panel 41 is mounted on the protective plate 11, preferably positioned in a location easily observable by the operator when holding the first handle 12 and the second handle 13 normally. A first LED, a second LED, and a third LED are sequentially arranged along the length of the light panel 41, together forming a first preset area for indicating the deflection state of the cutting plane S0. The horizontal detection mechanism 5 is configured to detect the deflection angle of the cutting plane S0 relative to the reference plane and output a detection value. The control mechanism 8 controls the lighting combination of the three LEDs within the first preset area based on the detection value, thereby achieving graded indication of different deflection degrees on the same light panel 41.

[0201] Specifically, the deflection angle of the cutting plane S0 can be divided into three ranges—small deflection, medium deflection, and large deflection—by presetting one or more deflection angle thresholds. For example, when the deflection angle corresponding to the detection value of the horizontal detection mechanism 5 is small, such as within approximately 5°, only the first LED is lit, and / or lit at a low brightness, as a first signal to indicate that the cutting plane S0 is basically within a safe range; when the deflection angle further increases, such as within the medium range of approximately 5° to 15°, the first and second LEDs are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED, as a second signal to indicate that the deflection angle has increased significantly and the operator needs to pay attention to adjustment; when the deflection angle increases to a large range, such as greater than approximately 15°, the first, second, and third LEDs are lit together, and / or the third LED is displayed in a high-brightness or flashing mode, as a third signal to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the values ​​of approximately 5° and approximately 15° mentioned above are exemplary settings. The angle changes can be, but are not limited to, gradual increases or decreases, proportional increases or decreases, or irregular increases or decreases. No specific limitations are made here. In actual applications, the dividing angles and the corresponding LED lighting combinations can be adjusted according to the structural dimensions of different tools, usage scenarios, and safety requirements. As long as the degree of brightness of the LED group 411 on the same light board 41 is used to achieve graded feedback on the size of the deflection angle, it falls within the protection scope of this disclosure.

[0202] For example, in one embodiment, a horizontal light plate 41 disposed in the middle of the protective plate 11 can be used to indicate the deflection state of the cutting plane S0 relative to the first reference plane S1. When the detection value of the horizontal detection mechanism 5 corresponds to the deflection angle of the cutting plane S0 relative to the first reference plane S1, the three lamps on the horizontal light plate 41 can be lit sequentially according to the above-mentioned boundary values ​​of approximately 5° and approximately 15°: when the deflection angle is within approximately 5°, only the first lamp near the center of the light plate is lit, indicating that the cutting plane S0 is basically within the target horizontal neutral range relative to the first reference plane S1; when the deflection angle is between approximately 5° and 15°, the first and second lamps are lit simultaneously, and the brightness of the second lamp can be higher than that of the first lamp, indicating that the deflection angle relative to the first reference plane S1 has increased significantly; when the deflection angle is greater than approximately 15°, the first, second, and third lamps are lit together, and the third lamp can be displayed in a high-brightness or flashing mode, indicating that the deflection angle of the cutting plane S0 relative to the first reference plane S1 is large.

[0203] In another embodiment, a side light panel 41 disposed on the left or right side of the protective plate 11 can be used to indicate the deflection state of the cutting plane S0 relative to the second reference plane S2. When the detection value of the horizontal detection mechanism 5 corresponds to the deflection angle of the cutting plane S0 relative to the second reference plane S2, the LEDs on the side light panel 41 are also lit in stages according to the boundary values ​​of about 5° and about 15°: when the deflection angle relative to the second reference plane S2 is small, only one LED near the center of the light panel is lit, indicating that the deflection is within the allowable range; when the deflection angle is in the medium range, two LEDs near the side of the deflection direction are lit in sequence or their brightness is increased; when the deflection angle exceeds a large threshold, multiple LEDs near the side of the deflection direction are lit simultaneously in a high-brightness or flashing manner to indicate that the deflection of the cutting plane S0 relative to the second reference plane S2 has exceeded the recommended range. To facilitate the differentiation of different reference planes, in some embodiments, the light panel 41 used to indicate the first reference plane S1 may adopt a first color or a first flashing mode, and the light panel 41 used to indicate the second reference plane S2 may adopt a different color or flashing mode, so that the operator can intuitively distinguish the deflection information of the cutting plane S0 relative to the first reference plane S1 and the second reference plane S2.

[0204] It should be noted that the descriptions of the number and arrangement of the light panels 41 in the above embodiments are merely illustrative and do not constitute a limitation of this disclosure. For example, in some embodiments, the indicating mechanism 4 may include only one light panel 41, which is horizontally arranged on the protective plate 11 and can be used to indicate the deflection state of the cutting plane S0. In other embodiments, the indicating mechanism 4 may include two light panels 41, respectively arranged on both sides of the protective plate 11, for indicating the deflection of the cutting plane S0 to different sides. In further embodiments, the indicating mechanism 4 may also include three or more light panels 41, arranged in the middle and / or on both sides of the protective plate 11 and / or on the opposite housing 1 portion of the protective plate 11, as long as it is convenient for the operator to observe the indicating information.

[0205] Furthermore, the number of LED bead groups 411 provided on the LED panel 41 and the number of LED beads contained in each LED bead group 411 are not limited to the above example. They can be increased, decreased or adjusted according to actual needs. As long as the deflection state of the cutting plane S0 can be indicated by the brightness, brightness position and / or display color of the LED bead group 411, it falls within the protection scope of this application.

[0206] The technical solution provided in Embodiment 2 of the present invention is as follows: See Figure 1 , Figure 2The trimming tool includes a housing 1, a cutting mechanism 2, a driving mechanism 3, an indicating mechanism 4, and a horizontal detection mechanism 5. A protective plate 11 is provided on the housing 1. The cutting mechanism 2 and the driving mechanism 3 are both located on the housing 1. The cutting mechanism 2 has a cutting plane S0. The driving mechanism 3 is configured to drive the cutting mechanism 2. The indicating mechanism 4 is located on the protective plate 11 and is configured to indicate the deflection state of the cutting plane S0 relative to a reference plane. The horizontal detection mechanism 5 is connected to the indicating mechanism 4 and is configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal. The reference plane includes a first reference plane S1 and / or a second reference plane S2.

[0207] In this embodiment, after the user activates the drive mechanism 3, the drive mechanism 3 drives the cutting mechanism 2 mounted on the housing 1 to rotate or reciprocate around a predetermined rotation axis or along a predetermined motion trajectory, thereby forming a cutting plane S0 on the surface of the workpiece to be trimmed. During the operation, the user holds the housing 1 with one or both hands, bringing the cutting plane S0 close to or near the target surface of the workpiece, and selects either the first reference plane S1 or the second reference plane S2 as a reference according to the site requirements. The horizontal detection mechanism 5 detects the deflection state of the cutting plane S0 relative to the currently selected reference plane in real time during the trimming process and outputs the corresponding detection signal; after receiving the detection signal from the horizontal detection mechanism 5, the indicator mechanism 4 converts the detection signal into an intuitive light signal display, for example, by changing the number of lamp beads or lamp bead group 411 lit, the lighting position and / or the display color, to provide feedback to the user on the deflection direction and degree of the cutting plane S0, allowing the user to fine-tune the tool posture at any time according to the indicator state while maintaining a normal grip and safe standing position, thereby completing the trimming operation of the target plane or target angle.

[0208] Therefore, the aforementioned structure and motion combination has several beneficial effects: Firstly, by setting a protective plate 11 on the housing 1 and arranging the indicating mechanism 4 on the protective plate 11, the indicating information is located close to the cutting area and in a position that is easy to observe. Combined with the real-time detection of the cutting plane S0 relative to the first reference plane S1 and / or the second reference plane S2 by the horizontal detection mechanism 5, it can dynamically reflect whether the tool posture deviates from the expected plane during the trimming process, which is beneficial to improving trimming accuracy and consistency. Secondly, it allows users to know the current cutting status without visually estimating the tool posture, reducing the deviation from experience-based judgments and lowering the risk of misoperation due to limited viewing angle, insufficient ambient light, or complex workpiece shape, thereby improving operational safety.

[0209] In this embodiment, when the indicating mechanism 4 is installed on the protective plate 11, the protective plate 11 can adopt different structural forms to adapt to different installation methods and protection requirements. The protective plate 11 can be a single-layer structure or a double-layer structure.

[0210] In some embodiments, the protective plate 11 is a single-layer structure, which can be integrally formed from a metal sheet or an engineering plastic sheet, with the side facing the operator forming a mounting surface for installing the indicator mechanism 4. The indicator mechanism 4 can be directly fixed to the mounting surface by means of screw connection, snap connection, or adhesive bonding, and the lead wire connected to the indicator mechanism 4 is led out to the inside of the housing 1 through a wire hole or opening provided on the protective plate 11. The single-layer structure of the protective plate 11 is simple in structure, has low manufacturing cost, is easy to process and assemble, and is suitable for occasions where the installation space requirement for the indicator mechanism 4 is small.

[0211] In other embodiments, the protective plate 11 has a double-layer structure, comprising a first protective layer 111 and a second protective layer 112 arranged sequentially along the front-rear direction of the trimming tool. The first protective layer 111 faces the cutting mechanism 2, and the second protective layer 112 faces the operator. The first protective layer 111 and the second protective layer 112 are spaced apart, forming a receiving space between them to accommodate the indicator mechanism 4. The indicator mechanism 4 is at least partially disposed within the receiving space, and its display surface S3 communicates with the outside through a window penetrating the second protective layer 112 for operator observation. The electrical connection leads of the indicator mechanism 4 are routed within the receiving space and led out to the interior of the housing 1. The double-layer structure of the protective plate 11, on the one hand, allows for the provision of installation space for the indicator mechanism 4 without significantly increasing the overall dimensions of the trimming tool; on the other hand, the first protective layer 111 blocks debris splashed during cutting, and the double-layer structure covers and protects the indicator mechanism 4 and its leads, thereby improving the protective performance and installation stability of the indicator mechanism 4.

[0212] It should be noted that this embodiment may be consistent with Embodiment 1 in some aspects of implementation, which will not be repeated here.

[0213] The technical solution provided in Embodiment 3 of the present invention is as follows: See Figure 1 , Figure 2 , Figure 3The trimming tool includes a housing 1, a horizontal detection mechanism 5, a first lead wire 6, a control mechanism 8, a cutting mechanism 2, a drive mechanism 3, a second lead wire 7, and an indicator mechanism 4. The horizontal detection mechanism 5 is mounted on the housing 1 and is configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal. One end of the first lead wire 6 is electrically connected to the horizontal detection mechanism 5 and is configured to transmit the detection signal obtained by the horizontal detection mechanism 5. The control mechanism 8 is mounted on the housing 1 and electrically connected to the other end of the first lead wire 6, and is configured to output a display signal based on the detection signal. The cutting mechanism 2 is mounted on the housing 1 and has a cutting plane S0. The drive mechanism 3 is configured to drive the cutting mechanism 2 to run. The second lead wire 7 and the indicator mechanism 4 are connected as follows: one end of the second lead wire 7 is electrically connected to the control mechanism 8, and the other end of the second lead wire 7 is connected to the indicator mechanism 4. The second lead wire 7 is configured to load a display signal to the indicator mechanism 4. The indicator mechanism 4 is configured to indicate the deflection state of the cutting plane S0 relative to the reference plane based on the display signal.

[0214] In this embodiment, after the trimming operation is started, the drive mechanism 3 drives the cutting mechanism 2 mounted on the housing 1 to operate, so that the cutting mechanism 2 forms a cutting plane S0 for processing the workpiece. During the operation, the horizontal detection mechanism 5 detects the deflection state of the cutting plane S0 relative to the reference plane in real time and generates a corresponding detection signal. The detection signal is transmitted to the control mechanism 8 mounted on the housing 1 via the first lead 6. The control mechanism 8 performs calculations and judgments based on the detection signal and outputs a display signal corresponding to the current deflection state. The display signal is transmitted to the indicator mechanism 4 via the second lead 7. The indicator mechanism 4 displays the signal according to a preset on / off mode, position change and / or color change, thereby intuitively indicating the deflection direction and degree of the cutting plane S0 relative to the reference plane. The operator can adjust the posture and movement path of the trimming tool in a timely manner according to the display results of the indicator mechanism 4, so that the cutting plane S0 tends to the target reference plane and completes the trimming operation.

[0215] The above setup clearly separates and electrically isolates the detection, calculation, and display functions, which helps reduce interference and attenuation during signal transmission and improves the accuracy and response speed of deflection state detection and display. The first lead 6 and the second lead 7 are used to transmit detection signals and display signals, respectively. The wiring path is clear and can be flexibly arranged according to the internal structure of the housing 1, reducing interference with moving parts such as the cutting mechanism 2 and the drive mechanism 3, and improving the reliability of the overall wiring and the convenience of assembly and maintenance. Through the real-time visual feedback of the deflection state of the cutting plane S0 by the indicating mechanism 4, the operator can know the tool posture deviation without relying on subjective visual inspection, thereby reducing misoperation, improving trimming accuracy and consistency, and to a certain extent reducing the reliance on the operator's vision and experience judgment during long-term operation, thus improving safety and ergonomics.

[0216] In some embodiments of this disclosure, the housing 1 has a first housing 14 with a first handle 12 and a second housing 14 with a second handle 13; wherein the first handle 12 is disposed at one end near the cutting mechanism 2, and the second handle 13 is disposed at one end away from the cutting mechanism 2; a protective plate 11 is disposed at one end of the housing 1 near the cutting mechanism 2; and an indicating mechanism 4 is disposed on the protective plate 11, or the indicating mechanism 4 is disposed on the housing 1 located between the first handle 12 and the second handle 13. Compared with the embodiment in which the indicating mechanism 4 is only fixed to the protective plate 11, the difference of this embodiment is that the installation position of the indicating mechanism 4 can also be optional between the protective plate 11 and the housing 1 area corresponding to the first handle 12 and the second handle 13: on the one hand, when the indicating mechanism 4 is disposed on the protective plate 11, it is closer to the cutting area, which is convenient for direct observation when working in a posture close to the workpiece; on the other hand, when the indicating mechanism 4 is disposed on the housing 1 between the first handle 12 and the second handle 13, it is closer to the area where the operator's hand is located, which is beneficial for obtaining a more comfortable viewing angle under different grip postures and different standing angles, and also facilitates the optimization of wiring and installation space according to the internal component layout of the housing 1. Therefore, by flexibly selecting the installation position of the indicator mechanism 4 between the corresponding areas of the protective plate 11 and the housing 1, a better balance can be achieved between indicator visibility, structural layout rationality and ergonomic performance, all of which fall within the protection scope of this disclosure.

[0217] In some embodiments of this disclosure, the first housing 14 and the second housing 15 are rotatably connected. (It is understood that when using the tool, the operator holds the second handle 13 on the second housing 15, keeping the second handle 13 and the second housing 15 relatively stationary in space. Based on operational needs, the operator applies force to rotate the first housing 14, which has the first handle 12 and the cutting mechanism 2, relative to the second housing 15, thereby changing the orientation of the cutting plane S0 relative to the reference plane.) The horizontal detection mechanism 5 is electrically connected to the indicating mechanism 4 and is configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal. In this embodiment, before the trimming tool is used, the operator can adjust the rotational position of the first housing 14 relative to the second housing 15 according to their height, gripping habits, and the spatial orientation of the object being trimmed, so that the first handle 12 and the cutting mechanism 2 are at a spatial angle suitable for the current operational posture. After adjustment, the operator holds the first handle 12 and the second handle 13 with one or both hands respectively, providing stable support to the second housing 15 and guiding it through the first housing 14. The drive mechanism 3 drives the cutting mechanism 2 to operate, forming the cutting plane S0 for trimming. At the same time, the horizontal detection mechanism 5 detects the deflection state of the cutting plane S0 relative to the reference plane in real time and outputs the detection signal to the indicator mechanism 4. The indicator mechanism 4 displays the light signal based on the detection signal (for example, by distinguishing the brightness, position and / or color of the LED group 411), so that even if the first housing 14 is in a different rotation position relative to the second housing 15, it can still intuitively provide feedback on the deflection direction and degree of the cutting plane S0, which makes it convenient for the operator to adjust the trimming posture in a timely manner.

[0218] By rotating the portion with the first housing 14 relative to the portion with the second housing 15, the second handle 13, serving as the main grip, remains essentially stationary during use. In different work scenarios (such as high-altitude trimming, low-altitude trimming, trimming against a wall, or trimming in confined spaces), the operator can rotate the portion with the first handle 12 and cutting mechanism 2 relative to the second handle 13 while maintaining a firm grip. This allows for adjustment of the relationship between the cutting plane S0 and the target plane in a more natural forearm and wrist posture, reducing joint twisting and muscle strain, and improving ergonomic comfort. Simultaneously, when changing the trimming direction or overall tool posture, the operator can regain stable support and a suitable cutting posture by adjusting the angle of the first housing 14, enhancing the machine's maneuverability and stability. Furthermore, when the tool is not in use, the first housing 14 can be rotated relative to the second housing 15 to the side closer to the second handle 13, reducing the overall size of the machine and facilitating storage and transportation.

[0219] It should be noted that, compared with the embodiment where the second handle 13 is fixedly mounted on the housing 1 and the overall posture of the housing 1 is basically fixed relative to the second handle 13, the difference in this embodiment is that the housing 1 includes a first housing 14 and a second housing 15. The first housing 14 is provided with a first handle 12 and a cutting mechanism 2, and the second housing 15 is provided with a second handle 13. The first housing 14 is rotatably connected relative to the second housing 15. In use, the operator mainly holds the second handle 13 mounted on the second housing 15, keeping the second housing 15 basically stationary in space, and applies force to rotate the first housing 14 relative to the second housing 15 to change the spatial posture of the cutting plane S0. While maintaining the electrical connection between the horizontal detection mechanism 5 and the indicating mechanism 4, and the real-time indication function of the deflection state of the cutting plane S0 relative to the first reference plane S1 and / or the second reference plane S2, the relative rotation structure between the first housing 14 and the second housing 15 is introduced. This allows the same detection and indication scheme to adapt to more grip postures and usage environments, thereby further improving the ergonomic comfort and applicability of the trimming tool without increasing the complexity of the core detection and display. In some embodiments of this disclosure, the indicating mechanism 4 includes at least one set of lamp panels 41; one end of the second lead 7 away from the control mechanism 8 extends to the central region of the protective plate 11 and is electrically connected to the input terminal of any set of lamp panels 41; or one end of the second lead 7 away from the control mechanism 8 extends to the side region of the protective plate 11 and is electrically connected to the input terminal of any set of lamp panels 41; wherein the second lead 7 is configured to load a display signal onto the lamp panel 41.

[0220] Furthermore, in this embodiment, the first housing 14 can rotate relative to the second housing 15 between at least three preset angle positions, the second handle 13 is disposed on the second housing 15 and remains basically stationary as the main grip during use, the horizontal detection mechanism 5 is always configured to detect the deflection state of the cutting plane S0 relative to the selected reference plane and output the detection value, and the control mechanism 8 selects the corresponding light panel 41 and its preset area for graded indication according to the current position of the first housing 14 relative to the second housing 15.

[0221] Specifically, when the first housing 14 is in the first position relative to the second housing 15, the control mechanism 8 compares the detection value output by the horizontal detection mechanism 5 with a preset first threshold: when the deflection angle corresponding to the detection value is small, for example, within about 5°, one LED is lit in the first preset area on the horizontal light panel 41 as a first signal; when the deflection angle corresponding to the detection value further increases, for example, in the range of about 5° to 15°, two LEDs are lit in the first preset area as a second signal; when the deflection angle corresponding to the detection value increases to a larger range, for example, greater than about 15°, three LEDs are lit in the first preset area, and if necessary, the third LED can also be displayed in a high-brightness or flashing mode as a third signal.

[0222] When the first housing 14 rotates to the second position relative to the second housing 15, the horizontal detection mechanism 5 still detects the deflection state of the cutting plane S0 relative to the reference plane and outputs the detection value. At this time, the control mechanism 8 selects the second preset area on the lamp plate 41 on the side corresponding to the second position of the protective plate 11 for display: when the deflection angle corresponding to the detection value is small (such as within about 5°), one lamp bead is lit in the second preset area as the first signal; when the deflection angle is in the medium range (such as about 5° to 15°), two lamp beads are lit in the second preset area as the second signal; when the deflection angle is large (such as greater than about 15°), three lamp beads are lit in the second preset area as the third signal.

[0223] Similarly, when the first housing 14 rotates to the third position relative to the second housing 15, the horizontal detection mechanism 5 continues to output the detection value reflecting the deflection state, and the control mechanism 8 selects the third preset area on the lamp plate 41 on the other side of the protective plate 11 corresponding to the third position for graded display: when the deflection angle corresponding to the detection value is small, one lamp bead is lit in the third preset area as the first signal; when the deflection angle is in the medium range, two lamp beads are lit in the third preset area as the second signal; when the deflection angle is large, three lamp beads are lit in the third preset area as the third signal.

[0224] For example, in one example, the reference plane can be set as the first reference plane S1. At this time, the detection value output by the horizontal detection mechanism 5 corresponds to the deflection angle of the cutting plane S0 relative to the first reference plane S1. When the first housing 14 is in the first position, it is preferable to provide graded indication through the horizontal light plate 41 in the middle of the protective plate 11. When the first housing 14 is in the second or third position, it is provided with graded indication through the preset areas corresponding to the light plates 41 on the left or right side of the protective plate 11, respectively. The operator can judge the degree of deflection of the cutting plane S0 relative to the first reference plane S1 based on the number of LED beads and / or the change in brightness.

[0225] In another example, the reference plane can be set as the second reference plane S2. In this case, the detection value output by the horizontal detection mechanism 5 corresponds to the deflection angle of the cutting plane S0 relative to the second reference plane S2. The light plate 41 on one side of the protective plate 11 can be configured to mainly indicate the deflection state relative to the second reference plane S2, while the light plate 41 in the middle or on the other side can be configured to indicate the deflection state relative to the first reference plane S1. The three intervals of small deflection, medium deflection and large deflection are still distinguished by the "one light, two lights, three lights" classification method. The deflection information corresponding to the first reference plane S1 and the second reference plane S2 can be distinguished by the difference in color, brightness and / or flashing mode of the lamp bead group 411.

[0226] It should be noted that the above-mentioned approximately 5° and approximately 15° are only exemplary values. The specific values ​​of the first threshold, the second threshold, and the third threshold, as well as the lighting combinations of the LEDs in each preset area, can be adjusted according to the actual product and safety requirements. As long as the degree of deflection of the cutting plane S0 relative to the selected reference plane is graded by the brightness of "one lamp, two lamps, and three lamps" in the corresponding preset area at different preset positions of the first housing 14 relative to the second housing 15 based on the detection value of the horizontal detection mechanism 5, it falls within the protection scope of this disclosure.

[0227] It should be noted that this embodiment may be consistent with Embodiment 1 in some aspects of implementation, which will not be repeated here.

[0228] The technical solution provided in Embodiment 4 of the present invention is as follows: See Figure 1 , Figure 2 , Figure 3 The trimming tool includes a housing 1, a cutting mechanism 2, a driving mechanism 3, an indicating mechanism 4, a sensing mechanism 9, and a control mechanism 8. The housing 1 includes a first housing 14 with a first handle 12 and a second housing 15 with a second handle 13. The first housing 14 and the second housing 15 are rotatably connected. The cutting mechanism 2 and the driving mechanism 3 are both located on the housing 1. The cutting mechanism 2 has a cutting plane S0, and the driving mechanism 3 is configured to drive the cutting mechanism 2 to run. The indicating mechanism 4 is located on the housing 1 corresponding to the first handle 12 and the second handle 13. The indicating mechanism 4 is configured to indicate the deflection state of the cutting plane S0 relative to the reference plane. The sensing mechanism 9 is located at the pivot between the first housing 14 and the second housing 15. It is configured to acquire the relative rotation information of the first housing 14 or the second housing 15 and output a rotation signal. The control mechanism 8 controls the indicating mechanism 4 to indicate within the area corresponding to the current posture based on the rotation signal. The deflection axis is a straight line extending along the length direction of the cutting plane S0 and parallel to the reference plane. The deflection state is the state in which the cutting plane S0 deflects relative to the reference plane around the deflection axis.

[0229] Before use, the operator can rotate the first housing 14 around the axis between it and the second housing 15 to a comfortable working posture according to their height, standing position, and working direction. This ensures that the first handle 12 and the cutting mechanism 2 on the first housing 14 are in an easy-to-operate position, while the second housing 15 and its second handle 13 remain essentially stationary in space. The sensing mechanism 9 acquires the rotation information of the first housing 14 in real time during the rotation of the first housing 14 relative to the second housing 15 and outputs a rotation signal to the control mechanism 8 (of course, the sensing mechanism 9 can also acquire the rotation information of the second housing 15 in real time and output a rotation signal to the control mechanism 8). Subsequently, the operator holds the second handle 13 on the second housing 15 and the first handle 12 on the first housing 14 with both hands, and starts the drive mechanism 3. The drive mechanism 3 drives the cutting mechanism 2 to run, forming a cutting plane S0 for trimming. During the trimming process, the cutting plane S0 deflects relative to the reference plane around a deflection axis that extends along the length of the cutting plane S0 and is parallel to the reference plane. Based on the rotation signal output by the sensing mechanism 9, the control mechanism 8 controls the indicator mechanism 4 set on the first housing 14 and the second housing 15 to indicate in the corresponding area according to the preset correspondence. This allows the operator to visually display the deflection state of the cutting plane S0 relative to the reference plane in the area closest to the operator, regardless of the angle position of the first housing 14 relative to the second housing 15. This makes it easy for the operator to observe and adjust the trimming posture at any time.

[0230] This configuration, by rotatably connecting the first housing 14 relative to the second housing 15 and setting a sensing mechanism 9 at the pivot between them to obtain the relative rotation information of the first housing 14 or the second housing 15 in real time, allows the spatial posture of the first handle 12 and the cutting mechanism 2 to be flexibly adjusted according to different working conditions (such as high-position trimming, low-position trimming, wall-hugging trimming, or trimming in narrow spaces) while the second handle 13 and the second housing 15 thereon serve as the main gripping reference and remain basically stationary during use. This ensures that the operator's forearm and wrist joints are in a comfortable and neutral posture, reducing joint twisting and muscle burden, and significantly improving ergonomics. Secondly, the control mechanism 8 selects and controls the working area of ​​the indicator mechanism 4 based on the rotation signal, so that the indicator mechanism 4 indicates within the area matching the current gripping posture. This avoids the difficulty in reading caused by the original indicator area turning to an obscure position after the first housing 14 rotates, while maintaining the overall compact structure of the tool and improving the visibility and readability of the indicator information. Third, by uniformly defining the deflection state as the state in which the cutting plane S0 deflects relative to the reference plane around the deflection axis extending along its length direction and parallel to the reference plane, the determination of the deflection angle is independent of the operator's grip, the relative rotation posture of the first housing 14 and the second housing 15, and the overall flipping posture of the tool. This ensures that the criteria for determining the deflection state are consistent under different postures, which is conducive to improving the repeatability and consistency of the trimming effect. Overall, it takes into account the safety, comfort and trimming accuracy of operation.

[0231] In some embodiments of this disclosure, the indicator mechanism 4 includes at least one set of light panels 41; the light panels 41 have multiple sets of light beads 411; the indicator mechanism 4 indicates the brightness and / or position of the light beads 411 and / or the display color change of the light beads 411 according to the signal loaded by the sensing mechanism 9.

[0232] Specifically, the indicating mechanism 4 is mounted on the housing 1 corresponding to the first handle 12 and the second handle 13. The indicating mechanism 4 can reflect the deflection angle of the cutting plane S0 through the brightness of different LEDs in the LED group 411 mounted thereon. For example, an LED group 411 may include at least three LEDs, namely a first LED, a second LED, and a third LED: when the deflection angle of the cutting plane S0 is small, only the first LED is lit, and / or lit at a low brightness, to indicate that the deflection is small and basically within the safe range; when the deflection angle of the cutting plane S0 further increases, the first LED and the second LED are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED, to indicate that the deflection angle is in the medium range and the operator needs to pay attention to adjustment; when the deflection angle of the cutting plane S0 increases to a large range, the first LED, the second LED, and the third LED are lit together, and / or the third LED is displayed in a high-brightness or flashing manner, to indicate that the deflection angle is large or even close to the upper limit of the allowable range, reminding the operator to adjust or stop the operation in time. It should be noted that the number of LEDs, the lighting sequence, and the brightness variation method described above can be adjusted according to actual needs, and this does not limit the scope of protection of this disclosure.

[0233] The deflection angle of the cutting plane S0 can also be reflected by the on / off position of different LEDs within the LED group 411. For example, an LED group 411 may include at least three LEDs arranged sequentially along a preset direction, namely, a first LED, a second LED, and a third LED: when the deflection angle of the cutting plane S0 is small, only the first LED located near the preset reference position is lit to indicate that the deflection is small and basically within a safe range; when the deflection angle of the cutting plane S0 further increases, the first LED is turned off, and only the second LED located in the middle position is lit to indicate that the deflection angle is in a medium range and requires the operator to pay attention to adjustment; when the deflection angle of the cutting plane S0 increases to a large range, only the third LED located on the side away from the reference position is lit, and / or the third LED flashes to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the number of LEDs, their arrangement, and the lighting positions corresponding to different deflection angles can be adjusted according to actual needs. For example, two or more LEDs at different positions can be lit simultaneously to represent a more detailed deflection range, which does not limit the scope of protection of this disclosure.

[0234] The deflection angle of the cutting plane S0 can also be reflected by the display color of the LEDs in the LED group 411. For example, an LED group 411 may include at least three LEDs, namely a first LED, a second LED, and a third LED: when the deflection angle of the cutting plane S0 is small, the first LED displays a first color, such as green, to indicate that the deflection is small and basically within a safe range; when the deflection angle of the cutting plane S0 further increases, the second LED displays a second color, such as yellow, to indicate that the deflection angle is in a medium range and the operator needs to pay attention to adjustment; when the deflection angle of the cutting plane S0 increases to a large range, the third LED displays a third color, such as red, and / or displays in a red flashing mode to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the first color, the second color, and the third color are not limited to the above examples of green, yellow, and red, and any color combination that is easily distinguishable from each other can be selected according to actual needs, and this does not limit the scope of protection of this disclosure.

[0235] In some embodiments of this disclosure, the housing 1 includes a first housing 14 with a first handle 12 and a second housing 15 with a second handle 13. The first housing 14 is rotatable relative to the second housing 15 between at least three preset positions. The horizontal detection mechanism 5 is always configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output the detection value. The control mechanism 8 selects the corresponding light panel 41 and its preset area for graded indication according to the current position of the first housing 14 relative to the second housing 15.

[0236] Specifically, when the first housing 14 is in the first position relative to the second housing 15, the control mechanism 8 compares the detection value output by the horizontal detection mechanism 5 with a preset first threshold, and / or second threshold, and third threshold: when the deflection angle corresponding to the detection value is small, for example, within about 5°, one LED is lit in the first preset area on the horizontal light panel 41 as a first signal; when the deflection angle corresponding to the detection value further increases, for example, in the range of about 5° to 15°, two LEDs are lit in the first preset area as a second signal; when the deflection angle corresponding to the detection value increases to a larger range, for example, greater than about 15°, three LEDs are lit in the first preset area, and if necessary, the third LED can also be displayed in a high-brightness or flashing mode as a third signal.

[0237] When the first housing 14 rotates to the second position relative to the second housing 15, the horizontal detection mechanism 5 still detects the deflection state of the cutting plane S0 relative to the reference plane and outputs the detection value. At this time, the control mechanism 8 selects the second preset area on the lamp plate 41 arranged on one side of the protective plate 11 for display: when the deflection angle corresponding to the detection value is small (such as within about 5°), one lamp bead is lit in the second preset area as the first signal; when the deflection angle is in the medium range (such as about 5° to 15°), two lamp beads are lit in the second preset area as the second signal; when the deflection angle is large (such as greater than about 15°), three lamp beads are lit in the second preset area as the third signal. Similarly, when the first housing 14 rotates to the third position relative to the second housing 15, the horizontal detection mechanism 5 continues to output the detection value reflecting the deflection state, and the control mechanism 8 selects the third preset area on the lamp plate 41 arranged on the other side of the protective plate 11 for graded display: when the deflection angle corresponding to the detection value is small, one lamp bead is lit in the third preset area as the first signal; when the deflection angle is in the medium range, two lamp beads are lit in the third preset area as the second signal; when the deflection angle is large, three lamp beads are lit in the third preset area as the third signal.

[0238] It should be noted that the above-mentioned approximately 5° and approximately 15° are only exemplary values. The specific values ​​of the first threshold, the second threshold, and the third threshold, as well as the lighting combinations of the LEDs in each preset area, can be adjusted according to the actual product and safety requirements. As long as the degree of deflection is graded by the brightness of "one lamp, two lamps, and three lamps" in the preset areas corresponding to different preset positions of the first housing 14 relative to the second housing 15 based on the detection value of the horizontal detection mechanism 5, it falls within the protection scope of this disclosure.

[0239] In this embodiment, the indicating mechanism 4 includes at least three light panels 41, which are respectively disposed at different positions on the housing 1. One light panel 41 is disposed approximately horizontally on the housing 1 along the length of the tool, and the other two light panels 41 are disposed on the left and right sides of the housing 1, respectively, and preferably are arranged substantially perpendicular to the horizontally disposed light panel 41. The second handle 13 is defined as the first position when it is in a gripping posture corresponding to the horizontally disposed light panel 41 relative to the housing 1; the second position is defined as the second position when it rotates around the axis to the left side of the housing 1 to a gripping posture corresponding to the left light panel 41; and the third position is defined as the third position when it rotates around the axis to the right side of the housing 1 to a gripping posture corresponding to the right light panel 41.

[0240] In some embodiments of this disclosure, the horizontal detection mechanism 5 includes, but is not limited to, angle sensors capable of detecting angle changes, such as gyroscopes and levels. The angle sensor is mounted on the housing 1 and has a fixed correspondence with the installation posture of the cutting mechanism 2. It is configured to detect the deflection angle of the cutting plane S0 relative to the reference plane and output a detection signal characterizing the deflection state. Based on the detection signal output by the angle sensor, the control mechanism 8 analyzes and grades the degree of deflection, thereby generating a display signal for driving the indicating mechanism 4, enabling the indicating mechanism 4 to visually indicate the deflection state of the cutting plane S0 relative to the reference plane.

[0241] In some embodiments of this disclosure, the sensing mechanism 9 includes, but is not limited to, Hall elements, photoelectric sensors, etc., capable of detecting position changes. For example, the Hall element is disposed at the pivot between the housing 1 and the second handle 13. In some embodiments, the Hall element can cooperate with a magnetic component mounted on the second handle 13 or the pivot to detect the rotational position and / or rotational angle of the second handle 13 relative to the housing 1, and output a rotation signal indicating that the second handle 13 is currently in a first, second, or third position. Based on the rotation signal output by the Hall element, the control mechanism 8 selects the lamp panel 41 and its preset display area corresponding to the current position of the second handle 13, and, in conjunction with the detection signal output by the horizontal detection mechanism 5, controls the LED bead group 411 on the corresponding lamp panel 41 to provide indication.

[0242] In this embodiment, the sensing mechanism 9 is a Hall sensor. The second handle 13 is rotatably connected to the housing 1 via a rotating shaft. The sensor (Hall element) of the second handle 13 is installed in the rotating shaft area, for example, fixed in a mounting cavity at one end of the rotating shaft, and cooperates with a magnet disposed on the rotating shaft to sense the rotation angle of the second handle 13 around the rotating shaft. When the second handle 13 rotates around the deflection axis, the position of the magnet relative to the Hall element changes, and the Hall element outputs an electrical signal corresponding to the rotation angle. This electrical signal is transmitted to the control mechanism 8 inside the housing 1 via a third lead. The control mechanism 8 collects and processes the electrical signal input via the third lead to determine the rotation direction of the second handle 13 relative to a reference position and the corresponding angle range.

[0243] After acquiring the rotation direction and angle information of the second handle 13, the control mechanism 8 sends a drive signal to the corresponding display light panel 41 via the second lead 7, causing the display light panel 41 in the area corresponding to the current rotation direction to emit light. For example, when the second handle 13 deflects to the left, the control mechanism 8 drives the display light panel 41 located in the left area to light up or change its display color; when the second handle 13 deflects to the right, the control mechanism 8 drives the display light panel 41 in the right area to light up. By adjusting the number, position, and / or display color of the lit LEDs, the rotation angle information is visually mapped onto the display light panel 41. The operator can determine the deflection direction and degree of the cutting plane S0 relative to the reference plane simply by observing the light changes, thus allowing for timely adjustment of the tool posture during operation.

[0244] Furthermore, the Hall element can also be used to implement interlock control between the second handle 13 and the start / stop of the entire machine. Specifically, the Hall element is configured to detect whether the second handle 13 is in a preset working position and / or whether it is being properly held by the operator; the control mechanism 8 only allows the start command issued by the main trigger to be valid when it receives a valid rotation signal from the Hall element (e.g., indicating that the second handle 13 is in any of the first, second, or third positions and meets the preset holding conditions), and the operator triggers the main trigger so that the drive mechanism 3 can be driven to run the cutting mechanism 2; when the Hall element detects that the second handle 13 is not in position, deviates from the safe position, or is released, the control mechanism 8 prohibits the drive mechanism 3 from starting, and / or cuts off the drive to the drive mechanism 3 during machine operation, causing the cutting mechanism 2 to stop working.

[0245] Through the above-mentioned interlocking control settings, even if the main trigger is accidentally activated, the trimming tool will not be started if the second handle 13 is not in the prescribed working posture or is not held correctly. This can effectively reduce the risk of accidental start-up, starting with one hand, or starting in an abnormal posture, thereby improving safety. At the same time, if the second handle 13 is released from the hand or accidentally deflected to an unsafe position during operation, the system can automatically stop or prohibit further driving, which helps to meet higher-level safety standards.

[0246] It should be noted that this embodiment may be consistent with Embodiment 1 in some aspects of implementation, which will not be repeated here.

[0247] The technical solution provided in Embodiment 5 of the present invention is as follows: See Figure 1 , Figure 2 and Figure 3The trimming tool includes a housing 1, a cutting mechanism 2, a driving mechanism 3, an indicating mechanism 4, and a horizontal detection mechanism 5. The housing 1 has a protective plate 11, a first handle 12, and a second handle 13. Both the cutting mechanism 2 and the driving mechanism 3 are located on the housing 1. The cutting mechanism 2 has a cutting plane S0, and the driving mechanism 3 is configured to drive the cutting mechanism 2. The indicating mechanism 4 is located on the protective plate 11, or on the housing 1 located between the first handle 12 and the second handle 13. The indicating mechanism 4 is configured to indicate the deflection state of the cutting plane S0 relative to a reference plane. The horizontal detection mechanism 5 is electrically connected to the indicating mechanism 4 and is configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal. The deflection axis is a straight line extending along the length of the cutting plane S0 and parallel to the reference plane. The deflection state is the state in which the cutting plane S0 deflects relative to the reference plane around the deflection axis.

[0248] By simultaneously providing a first handle 12 and a second handle 13 on the housing 1, and arranging the indicator mechanism 4 on the protective plate 11 and / or in the housing 1 area between the first handle 12 and the second handle 13, the position of the indicator mechanism 4 corresponds to the operator's normal grip area, facilitating direct observation of the indicator information by the operator in a normal grip posture. In conjunction with the horizontal detection mechanism 5, the deflection state of the cutting plane S0 relative to the reference plane is detected in real time. Using a straight line extending along the length of the cutting plane S0 and parallel to the reference plane as the deflection axis, the deflection state is clearly defined as the state of the cutting plane S0 deflecting relative to the reference plane around the deflection axis, thus providing a clear and consistent description of the tool's posture in a geometric sense. Therefore, on the one hand, the operator can intuitively know whether the cutting plane S0 deviates from the expected reference plane according to the display of the indicator mechanism 4, and adjust the operating posture in time to improve the trimming accuracy and consistency; on the other hand, the definition of the deflection axis and deflection state is clear, which is conducive to adopting the same judgment standard under different working conditions (such as near-horizontal trimming or near-vertical trimming), reducing the error caused by differences in observation angle and experience, while maintaining the compact structure of the tool and improving the overall ergonomic performance and safety of use.

[0249] In this embodiment, when the indicating mechanism 4 is mounted on the protective plate 11, the protective plate 11 can adopt different structural forms to adapt to different installation methods and protection requirements. The protective plate 11 can be a single-layer structure or a double-layer structure.

[0250] In some embodiments, the protective plate 11 is a single-layer structure, which can be integrally formed from a metal sheet or an engineering plastic sheet, with the side facing the operator forming a mounting surface for installing the indicator mechanism 4. The indicator mechanism 4 can be directly fixed to the mounting surface by means of screw connection, snap connection, or adhesive bonding, and the lead wire connected to the indicator mechanism 4 is led out to the inside of the housing 1 through a wire hole or opening provided on the protective plate 11. The single-layer structure of the protective plate 11 is simple in structure, has low manufacturing cost, is easy to process and assemble, and is suitable for occasions where the installation space requirement for the indicator mechanism 4 is small.

[0251] In other embodiments, the protective plate 11 has a double-layer structure, comprising a first protective layer 111 and a second protective layer 112 arranged sequentially along the front-rear direction of the trimming tool. The first protective layer 111 faces the cutting mechanism 2, and the second protective layer 112 faces the operator. The first protective layer 111 and the second protective layer 112 are spaced apart, forming a receiving space between them to accommodate the indicator mechanism 4. The indicator mechanism 4 is at least partially disposed within the receiving space, and its display surface S3 communicates with the outside through a window penetrating the second protective layer 112 for operator observation. The electrical connection leads of the indicator mechanism 4 are routed within the receiving space and led out to the interior of the housing 1. The double-layer structure of the protective plate 11, on the one hand, allows for the provision of installation space for the indicator mechanism 4 without significantly increasing the overall dimensions of the trimming tool; on the other hand, the first protective layer 111 blocks debris splashed during cutting, and the double-layer structure covers and protects the indicator mechanism 4 and its leads, thereby improving the protective performance and installation stability of the indicator mechanism 4.

[0252] It should be noted that the second handle 13 is fixedly connected to the housing 1, meaning that the installation posture of the second handle 13 relative to the housing 1 is fixed and it does not have the function of rotating around a pivot. By adopting a fixed connection structure, the mechanical fit between the handle and the housing 1 can be simplified, reducing the number of rotating mechanisms, limiting structures, and corresponding sensing components. This helps to reduce component costs and assembly difficulty, and improves the overall structural strength and long-term reliability of the machine. Simultaneously, for routine trimming operations, it can provide a stable and consistent grip posture, allowing operators to develop fixed operating habits after becoming familiar with the tool, further improving operational stability. It should be noted that this embodiment is only an example configuration of a fixed connection between the handle and the housing 1, and it does not preclude the possibility of using a rotatable connection for the second handle 13 in other embodiments to accommodate more grip postures.

[0253] Further, in this embodiment, the description will be based on an example where the indicating mechanism 4 includes only one light panel 41. The light panel 41 is disposed on the protective plate 11, preferably in a position easily observed by the operator when normally holding the first handle 12 and the second handle 13; a first LED, a second LED, and a third LED are sequentially disposed on the light panel 41 along its length, and the three together constitute a first preset area for indicating the deflection state of the cutting plane S0. The horizontal detection mechanism 5 is configured to detect the deflection angle of the cutting plane S0 relative to the reference plane and output the detection value. The control mechanism 8 controls the lighting combination of the three LEDs in the first preset area according to the detection value, so as to realize graded indication of different deflection degrees on the same light panel 41.

[0254] Specifically, the deflection angle of the cutting plane S0 can be divided into three ranges—small deflection, medium deflection, and large deflection—by presetting one or more deflection angle thresholds. For example, when the deflection angle corresponding to the detection value of the horizontal detection mechanism 5 is small, such as within approximately 5°, only the first LED is lit, and / or lit at a low brightness, as a first signal to indicate that the cutting plane S0 is basically within a safe range; when the deflection angle further increases, such as within the medium range of approximately 5° to 15°, the first and second LEDs are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED, as a second signal to indicate that the deflection angle has increased significantly and the operator needs to pay attention to adjustment; when the deflection angle increases to a large range, such as greater than approximately 15°, the first, second, and third LEDs are lit together, and / or the third LED is displayed in a high-brightness or flashing mode, as a third signal to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the values ​​of approximately 5° and approximately 15° mentioned above are exemplary settings. In actual applications, the dividing angles and the corresponding LED lighting combinations can be adjusted according to the structural dimensions of different tools, usage scenarios, and safety requirements. As long as the degree of brightness of the LED group 411 on the same light board 41 is used to achieve graded feedback on the size of the deflection angle, it falls within the protection scope of this disclosure.

[0255] It should be noted that the descriptions of the number and arrangement of the lamp panels 41 in the above embodiments are merely illustrative and do not constitute a limitation of this disclosure. For example, in some embodiments, the indicating mechanism 4 may include only one lamp panel 41, which is horizontally arranged on the protective plate 11 and can be used to indicate the deflection state of the cutting plane S0.

[0256] It should be noted that this embodiment may be consistent with Embodiment 1 in some aspects of implementation, which will not be repeated here.

[0257] The technical solution provided in Embodiment Six of the present invention is as follows: See Figures 1 to 3The trimming tool includes a housing 1, a cutting mechanism 2, a driving mechanism 3, an indicating mechanism 4, a horizontal detection mechanism 5, and a control mechanism 8. A protective plate 11 is provided on the housing 1. Both the cutting mechanism 2 and the driving mechanism 3 are installed inside or on the housing 1. The cutting mechanism 2 has a cutting plane S0, and the driving mechanism 3 is configured to drive the cutting mechanism 2 to form the cutting plane S0 for trimming. The indicating mechanism 4 is located on the protective plate 11 or on the housing 1 located between the protective plate 11 and the driving mechanism 3, and is used to indicate the deflection state of the cutting plane S0 relative to a reference plane. The horizontal detection mechanism 5 is installed on the housing 1 and is used to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal to the control mechanism 8. The control mechanism 8 is electrically connected to the horizontal detection mechanism 5 and the indicating mechanism 4. The control mechanism 8 compares the detection signal with a preset threshold, outputs a first signal and a second signal, and drives the indicating mechanism 4 to indicate within the corresponding preset area according to the detection signal. The operating states of the indicating mechanism 4 corresponding to the first signal and the second signal are different. The state in which the cutting plane S0 rotates about the deflection axis L0 relative to the reference plane is defined as the deflection state, with the straight line extending along the length direction of the cutting plane S0 and parallel to the reference plane as the deflection axis L0.

[0258] In this embodiment, the control mechanism 8 is pre-set with multiple preset thresholds, including a first threshold, and / or a second threshold, and a third threshold. The control mechanism 8 calculates the deflection angle of the cutting plane S0 relative to the reference plane based on the detection signal output by the horizontal detection mechanism 5, and compares the deflection angle value with the first threshold, and / or the second threshold, and the third threshold to determine the threshold range to which the current deflection state belongs. The first threshold, the second threshold, and the third threshold correspond spatially to different preset areas on the indicating mechanism 4, for example, to the first preset area located in the middle, the second preset areas located on both sides of the middle, and the third preset area located on the outermost side, thus establishing a one-to-one correspondence between the numerical thresholds and the visual display positions. The numerical values ​​of each threshold can be set to be the same or different. For example, in a symmetrical arrangement, the first threshold, the second threshold, and the third threshold can be set to the same absolute value, but the deflection direction and degree can be distinguished by different display areas.

[0259] Specifically, in one exemplary embodiment, the deflection angle of the cutting plane S0 can be divided into three intervals: small deflection, medium deflection, and large deflection, by presetting a first threshold, a second threshold, and a third threshold. For example, the first threshold can be set to approximately 5°, the second threshold can be set to approximately 15°, and the third threshold can be used to limit the upper limit of the large deflection interval or an alarm threshold.

[0260] When the deflection angle corresponding to the detection value of the horizontal detection mechanism 5 is small, for example, when the absolute value of the deflection angle is less than or equal to the first threshold (e.g., within about 5°), only the first LED is lit, and / or lit with a lower brightness, as the first signal, corresponding to the first working state of the indicating mechanism 4, used to indicate that the cutting plane S0 is basically within a safe range; when the deflection angle further increases and is between the first threshold and the second threshold, for example, in a medium range of about 5° to 15°, the first LED and the second LED are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED. The first LED, as the second signal, corresponds to the second working state of the indicating mechanism 4, indicating that the deflection angle has increased significantly and the operator needs to pay attention to adjustment; when the deflection angle continues to increase and exceeds the second threshold, for example, when the absolute value of the deflection angle is greater than about 15° and less than or equal to the third threshold, the first, second, and third LEDs light up together, and / or the third LED displays in a high-brightness or flashing manner, as the third signal, corresponding to the third working state of the indicating mechanism 4, indicating that the deflection angle is too large, reminding the operator to adjust in time or stop the operation.

[0261] Optionally, the first, second, and third thresholds can be set to an increasing relationship in terms of value, or they can be set to the same or different values ​​according to the spatial correspondence between different display areas and / or different LED bead groups 411 on the light panel 41. It is only necessary to ensure that each threshold has a clear correspondence between its numerical range and the corresponding display area. For example, the first threshold corresponds to the central area of ​​the light panel 41, the second threshold corresponds to the areas on both sides of the central area, and the third threshold corresponds to the outermost area. It should be noted that the values ​​of approximately 5° and approximately 15° mentioned above are exemplary settings. In actual applications, the specific values ​​of each threshold and the corresponding LED bead lighting combinations can be adjusted according to the structural dimensions of different tools, usage scenarios, and safety requirements. As long as the graded feedback of the deflection angle is achieved by changing the brightness and / or brightness position of the LED beads in the LED bead group 411 on the same light panel 41, and / or the display color of the LED beads, this falls within the protection scope of this disclosure.

[0262] In a preferred embodiment, the indicating mechanism 4 includes at least one light panel 41 and a plurality of LEDs disposed on the light panel 41. When the control mechanism 8 outputs a first signal and a second signal, it controls the operating state of the indicating mechanism 4 to change. The operating state corresponds to the brightness and / or position of the LEDs, and / or the change in the display color of the LEDs. Specifically, different deflection states can be visually distinguished by changing the brightness of the LEDs (e.g., constantly lit, off, or flashing at different frequencies), changing the position of the lit LEDs on the indicating mechanism 4 (e.g., lighting only the LEDs near the center, sequentially extending the lighting to both sides, or lighting only the LEDs near one side), and / or changing the display color of the LEDs (e.g., green indicating the deflection angle is within the target range, yellow indicating the deflection angle is close to the threshold, and red indicating the deflection angle exceeds the threshold). When the deflection angle falls within the range bounded by the first threshold, the control mechanism 8 can drive the LED beads in the first preset area to work in the first working state; when the deflection angle falls within the range bounded by the second threshold or the third threshold, the control mechanism 8 can drive the LED beads in the second preset area or the third preset area to work in another working state, thereby clearly feeding back to the operator the deflection direction and degree of the cutting plane S0 relative to the reference plane through the changes in the brightness, brightness position and / or display color of the LED beads.

[0263] In some embodiments, when the indicating mechanism 4 is mounted on the protective plate 11, the protective plate 11 can adopt different structural forms to adapt to different installation methods and protection requirements. The protective plate 11 can be a single-layer structure or a double-layer structure.

[0264] In some embodiments, the protective plate 11 is a single-layer structure, which can be integrally formed from a metal sheet or an engineering plastic sheet, with the side facing the operator forming a mounting surface for installing the indicator mechanism 4. The indicator mechanism 4 can be directly fixed to the mounting surface by means of screw connection, snap connection, or adhesive bonding, and the lead wire connected to the indicator mechanism 4 is led out to the inside of the housing 1 through a wire hole or opening provided on the protective plate 11. The single-layer structure of the protective plate 11 is simple in structure, has low manufacturing cost, is easy to process and assemble, and is suitable for occasions where the installation space requirement for the indicator mechanism 4 is small.

[0265] In other embodiments, the protective plate 11 has a double-layer structure, comprising a first protective layer 111 and a second protective layer 112 arranged sequentially along the front-rear direction of the trimming tool. The first protective layer 111 faces the cutting mechanism 2, and the second protective layer 112 faces the operator. The first protective layer 111 and the second protective layer 112 are spaced apart, forming a receiving space between them to accommodate the indicator mechanism 4. The indicator mechanism 4 is at least partially disposed within the receiving space, and its display surface S3 communicates with the outside through a window penetrating the second protective layer 112 for operator observation. The electrical connection leads of the indicator mechanism 4 are routed within the receiving space and led out to the interior of the housing 1. The double-layer structure of the protective plate 11, on the one hand, allows for the provision of installation space for the indicator mechanism 4 without significantly increasing the overall dimensions of the trimming tool; on the other hand, the first protective layer 111 blocks debris splashed during cutting, and the double-layer structure covers and protects the indicator mechanism 4 and its leads, thereby improving the protective performance and installation stability of the indicator mechanism 4.

[0266] It should be noted that the difference between this embodiment and embodiment four is that in embodiment four, the indicator mechanism 4 is set on the protective plate 11 or on the housing 1 between the first handle 12 and the second handle 13; while in this embodiment, the indicator mechanism 4 can not only be set on the protective plate 11, but also on the housing 1 area corresponding to the first handle 12 and the second handle 13, thereby satisfying different structural design requirements and shape design requirements, and further optimizing the arrangement position of the indicator mechanism 4 relative to the operator's gripping area.

[0267] In some embodiments of this disclosure, the indicating mechanism 4 includes at least one lamp plate 41 with at least three LED beads on it; the trimming tool also includes a horizontal detection mechanism 5 and a control mechanism 8; the horizontal detection mechanism 5 is disposed on the housing 1 and configured to detect the deflection state of the cutting plane S0 relative to the reference plane and output a detection signal; the control mechanism 8 controls the indicating mechanism 4 to indicate in its corresponding area according to the rotation information based on the rotation signal, and causes the indicating mechanism 4 to change the brightness and / or brightness position of at least three LED beads and / or the display color of the LED beads according to the detection signal.

[0268] Specifically, at least three LEDs can be used: a first LED, a second LED, and a third LED (taking three LEDs as an example): When the deflection angle of the cutting plane S0 is small, only the first LED is lit, and / or lit at a lower brightness, to indicate that the deflection is small and basically within the safe range; when the deflection angle of the cutting plane S0 further increases, the first and second LEDs are lit simultaneously, and / or the brightness of the second LED is higher than that of the first LED, to indicate that the deflection angle is in the medium range and requires the operator to make adjustments; when the deflection angle of the cutting plane S0 increases to a larger range, the first, second, and third LEDs are lit together, and / or the third LED displays in a high-brightness or flashing mode, to indicate that the deflection angle is large or even close to the upper limit of the allowable range, reminding the operator to adjust or stop the operation in time. It should be noted that the number of LEDs, the lighting order, and the brightness change method described above can be adjusted according to actual needs and do not constitute a limitation on the protection scope of this disclosure.

[0269] As another example, the deflection angle of the cutting plane S0 can be reflected by the on / off positions of different LEDs among at least three LEDs. For instance, when the deflection angle of the cutting plane S0 is small, only the first LED near the preset reference position is lit, indicating that the deflection is small and basically within the safe range; when the deflection angle of the cutting plane S0 further increases, the first LED is turned off, and only the second LED in the middle position is lit, indicating that the deflection angle is in the medium range and the operator needs to pay attention to adjustment; when the deflection angle of the cutting plane S0 increases to a large range, only the third LED on the side away from the reference position is lit, and / or the third LED flashes, indicating that the deflection angle is large, reminding the operator to adjust or stop the operation in time.

[0270] It should be noted that the number of LEDs, their arrangement, and the lighting positions corresponding to different deflection angles can be adjusted according to actual needs. For example, two or more LEDs at different positions can be lit simultaneously to represent a more detailed deflection range, which does not limit the scope of protection of this disclosure.

[0271] As another example, the deflection angle of the cutting plane S0 can be reflected by the display colors of at least three LEDs. For instance, when the deflection angle of the cutting plane S0 is small, the first LED displays a first color, such as green, to indicate that the deflection is small and basically within a safe range; when the deflection angle of the cutting plane S0 further increases, the second LED displays a second color, such as yellow, to indicate that the deflection angle is in a medium range and requires adjustment by the operator; when the deflection angle of the cutting plane S0 increases to a large range, the third LED displays a third color, such as red, and / or displays in a flashing red manner to indicate that the deflection angle is large, reminding the operator to adjust or stop the operation in time. It should be noted that the first, second, and third colors are not limited to the above-mentioned examples of green, yellow, and red, and any color combination that is easily distinguishable from each other can be selected according to actual needs, without limiting the scope of protection of this disclosure.

[0272] In the above embodiments, the control mechanism 8 includes a first control board 81 and a second control board 82. The first control board 81 is located at the housing 1 corresponding to the second handle 13. The first control board 81 is equipped with buttons such as a speed control switch for adjusting the working parameters of the drive mechanism 3 and an indicator control switch for setting the working mode of the indicator mechanism 4, and is used to collect the operator's operation signals on the second handle 13. The second control board 82 is located inside the housing 1 between the first handle 12 and the second handle 13. The second control board 82 is electrically connected to the drive mechanism 3, the indicator mechanism 4, and the battery pack, and is used to centrally process the signals from the first control board 81 and the level detection mechanism 5 and output control signals.

[0273] When the horizontal detection mechanism 5 is installed on the second handle 13, one end of the first lead 6 is electrically connected to the horizontal detection mechanism 5 and the other end is electrically connected to the second control board 82. The first lead 6 is configured to transmit the detection signal obtained by the horizontal detection mechanism 5 to the second control board 82. The second control board 82 filters, calculates and determines the threshold of the detection signal transmitted through the first lead 6 to obtain the deflection state of the cutting plane S0 relative to the first reference plane S1 and / or the second reference plane S2. Based on the preset determination rule, it generates a display signal for driving the indicator mechanism 4 and outputs it to the indicator mechanism 4 through the second lead 7, so that the lamp plate 41 and the lamp bead group 411 installed on the housing 1 between the protective plate 11 and / or the protective plate 11 and the driving mechanism 3 display the deflection direction and / or deflection degree of the cutting plane S0.

[0274] The first control board 81 is equipped with operation buttons at corresponding positions. The operator can trigger the first control board 81 to output angle detection commands and / or working mode switching commands to the second control board 82 by pressing the buttons. The second control board 82 processes the detection signals collected by the horizontal detection mechanism 5 according to the commands from the first control board 81, and drives the indicator mechanism 4 to update the display content through the second lead 7, thereby realizing the detection, judgment and prompting of the deflection angle of the cutting plane S0.

[0275] As an example, in some embodiments, a display terminal may also be provided on the housing 1. The display terminal is electrically connected to the second control board 82. The operator issues angle detection commands and / or working mode switching commands by touching or pressing on the display terminal. The second control board 82 then processes the output signal of the horizontal detection mechanism 5 and drives the indicator mechanism 4 accordingly. Its function is similar to the control process achieved by the button operation of the first control board 81.

[0276] The trimming tool also includes a third lead 71 configured to make an electrical connection between adjacent light panels 41 for transmitting and distributing display signals among multiple light panels 41; the trimming tool also includes a fourth lead 72 configured to electrically connect the second control board 82 to the battery pack to provide operating power to the second control board 82 and the indicator mechanism 4 electrically connected thereto.

[0277] Furthermore, in some implementations, see [link to implementation details]. Figure 8 , Figure 9 The trimming tool also includes a first shock-absorbing unit DU1; one end of the first shock-absorbing unit DU1 is connected to the drive mechanism 3, and the other end of the first shock-absorbing unit DU1 is positioned horizontally toward the inner wall of the housing 1 corresponding to the drive mechanism 3, with a gap reserved between it and the inner wall of the housing 1 in a static state, so that when the drive mechanism 3 vibrates horizontally, the first shock-absorbing unit DU1 can move and abut against the inner wall of the housing 1 in a horizontal direction; alternatively, one end of the first shock-absorbing unit DU1 can be connected to the inner wall of the housing 1, and the other end of the first shock-absorbing unit DU1 can be positioned horizontally toward the drive mechanism 3, with a gap reserved between it and the drive mechanism 3 in a static state, so that when the drive mechanism 3 vibrates horizontally, the first shock-absorbing unit DU1 can move and abut against the drive mechanism 3 in a horizontal direction; wherein, the horizontal direction is defined as the direction in which the trimming tool extends along the width direction of the first handle 12 when it is in a normal use posture.

[0278] In some embodiments, the first damping unit DU1 can also be in contact with the inner wall of the housing 1 within the range of assembly tolerances. The first damping unit DU1 buffers and limits the displacement of the drive mechanism 3 in the horizontal direction through its own elastic deformation.

[0279] As an example, there are two first damping units DU1, respectively arranged on the left and right sides of the drive mechanism 3 along the length of the cutting mechanism 2. For example, two first damping units DU1 are arranged on the left and right sides of the housing of the drive motor 31 to provide symmetrical lateral damping support for the drive mechanism 3. In other embodiments, one or more first damping units DU1 can be set, and the specific number and position can be designed according to the structural dimensions and vibration characteristics of the drive mechanism 3. By allowing the first damping units DU1 to have a pre-reserved gap with the inner wall of the housing 1, or to directly abut against the housing 1 under certain assembly conditions, the first damping units DU1 can provide flexible clearance space in the early stage of vibration, and form elastic limiting support when the displacement reaches a certain amount, which is beneficial to balance the damping effect and structural stability under different working conditions. By symmetrically arranging two first damping units DU1 on the left and right sides of the drive motor 31, the support torque distribution of the drive mechanism 3 in the horizontal direction is more uniform, which can effectively suppress the sway and torsion of the motor assembly, further reduce vibration and noise transmission, and improve the overall running stability and user grip comfort.

[0280] As one embodiment, the first damping unit DU1 is made of flexible material.

[0281] The first damping unit DU1 enhances elastic feedback by using a hollowed-out structure, while maintaining a certain material flexibility. In some implementations, see Figure 8 , Figure 9 The trimming tool also includes a second damping unit DU2; the second damping unit DU2 is located between the housing 1 and the drive mechanism 3; it is configured to mitigate the effect of the movement of the drive mechanism 3 on the housing 1.

[0282] As an example, along the length of the first handle 12, the thickness of the second damping unit DU2 is between 2.9 and 3.5 mm.

[0283] As another example, see Figure 8 , Figure 9 , Figure 10 and Figure 11 The drive mechanism 3 includes a drive motor 31 and a drive seat 32; the drive seat 32 is installed in the cavity of the housing 1, and along the length of the first handle 12, the distance between the drive seat 32 and the second shock absorber DU2 on the side closest to each other is between 2 and 5 mm.

[0284] By setting a second damping unit DU2 between the housing 1 and the drive mechanism 3, and limiting the thickness of the second damping unit DU2 to 2.9-3.5 mm and the distance between it and the drive seat 32 on the side closest to each other to 2-5 mm, the second damping unit DU2 is in a suitable pre-tightening and deformation range after assembly. This is beneficial for effectively absorbing and attenuating the vibration and impact generated by the drive motor 31 during operation, reducing the amplitude of vibration transmitted to the housing 1, reducing the shaking sensation of the first handle 12 and the second handle 13, and improving the operator's grip comfort. At the same time, it can reduce the fatigue damage of long-term vibration to the connection part of the housing 1, the internal circuit board and fasteners, thereby improving the structural reliability and service life of the trimming tool.

[0285] As another example, see Figure 8 , Figure 9 The trimming tool also includes a third shock-absorbing unit DU3; the third shock-absorbing unit DU3 is located between the housing 1 and the cutting mechanism 2. For example, the third shock-absorbing unit DU3 can be a silicone shock-absorbing pad.

[0286] By setting a third damping unit DU3 between the housing 1 and the cutting mechanism 2, such as using a silicone damping pad, the instantaneous impact and high-frequency vibration generated by the cutting mechanism 2 when it comes into contact with the workpiece, breaks, or gets stuck are buffered and filtered before being transmitted to the housing 1. This helps to reduce the disturbance of the overall machine posture caused by tool biting and jumping, improve the stability and neatness of the cutting plane S0, and reduce cutting noise. The silicone material has good elasticity and resilience, and can maintain stable damping performance under multiple compression conditions. It also has certain aging resistance and temperature resistance, which helps to improve the long-term stability of the damping effect.

[0287] As another example, see Figure 8 , Figure 9 The trimming tool also includes a fourth damping unit DU4; the fourth damping unit DU4 is located between the housing 1 and the drive mechanism 3. It is configured to mitigate the effect of the drive mechanism 3 on the housing 1. For example, the fourth damping unit DU4 can be a soft rubber damping pad.

[0288] By setting a fourth damping unit DU4 between the housing 1 and the drive mechanism 3, and using soft rubber damping pads, the small-amplitude and low-frequency vibrations generated by the drive mechanism 3 during normal operation are first absorbed and dissipated by the soft rubber damping pads, which helps to further reduce the transmission of vibration to the housing 1, handle and indicator mechanism 4; the relatively low hardness of soft rubber can provide a large deformation stroke without significantly increasing the structural rigidity, thereby playing a smooth transition and buffering role when the drive mechanism 3 starts and stops or changes in speed, reducing abnormal noise and impact, and improving the smoothness and quietness of the whole machine operation.

[0289] As another example, see Figure 8 , Figure 9 The trimming tool also includes a fifth damping unit DU5, which is located between the housing 1 and the drive mechanism 3. It is configured to mitigate the impact of the drive mechanism 3 on the housing 1. For example, the fifth damping unit DU5 can be a hard rubber damping pad. By setting the fifth damping unit DU5 between the housing 1 and the drive mechanism 3 and using a hard rubber damping pad, the fifth damping unit DU5 provides a certain damping capacity while also providing high support stiffness and positioning accuracy for the drive mechanism 3. Under conditions of large external impact, drop, or high-load cutting, it helps to limit the displacement and deflection of the drive mechanism 3, preventing excessive swaying or collision between the drive motor 31 and the reduction mechanism relative to the housing 1. Compared to a completely rigid connection, the hard rubber damping pad can still absorb high-frequency impacts to a certain extent, thus ensuring structural strength and installation stability while also taking into account damping and protection effects, further improving the reliability of the entire machine under complex working conditions.

[0290] In this embodiment, the third damping unit DU3 and the fifth damping unit DU5 are mainly used to counteract the vibration generated by the drive mechanism 3 in the vertical direction; the fourth damping unit DU4 is used to further weaken the vibration effect of the drive mechanism 3 in the second direction. Specifically, the first direction can be understood as the direction consistent with the blade length direction in the tool cross section, and the second direction is the direction perpendicular to the first direction in the cross section. The vibration of the drive mechanism 3 in the above-mentioned directions is limited by the third damping unit DU3, the fourth damping unit DU4, and the fifth damping unit DU5, so that the amplitude of the drive mechanism 3 is constrained within a preset range of multiple spatial degrees of freedom. By arranging damping units at different positions between the mechanism and the left and right housings, a structurally isolated contact relationship is formed between the mechanism and the housing 1, and the whole presents a state similar to a suspended installation; combined with the design of soft rubber damping structures with different hardnesses and the frequency response characteristics of soft rubber, components with similar natural frequencies can be effectively isolated, thereby significantly weakening the transmission of vibration between the mechanism and the housing, reducing noise and improving the overall stability of the machine operation.

[0291] Understandably, different damping units employ differentiated elastic designs. For example, the elastic coefficients of the second damping unit DU2 and the fifth damping unit DU5 are lower than those of the first damping unit DU1, the third damping unit DU3, and the fourth damping unit DU4, providing softer support in the corresponding directions to absorb larger amplitude vibration displacements. Although the third damping unit DU3 can be made of the same material as the first and fourth damping units DU1 and DU4, its overall elastic coefficient is greater than that of the first and fourth damping units DU1 and DU4 by incorporating slots or openings in its structure. This provides relatively higher stiffness support and limiting capability in the vertical direction, which is beneficial for precisely controlling the vibration amplitude of the blade assembly and transmission mechanism in the vertical direction, achieving graded isolation and optimized suppression of vibrations in different directions.

[0292] It should be noted that this embodiment may be consistent with Embodiment 1 in some aspects of implementation, which will not be repeated here.

[0293] In some implementations, see Figure 8 The trimming tool also includes a chip baffle 10. The chip baffle 10 is disposed on the housing 1, located outside the cutting mechanism 2, and extends at least partially along the length of the cutting mechanism 2 on one side of the cutting plane S0, so that the chip baffle 10 is close to the edge of the cutting mechanism 2 to block and guide the chips generated during cutting. In a cross-section including the normal direction of the cutting plane S0, the chip baffle 10 is arranged in an arc shape, with a concave surface facing the cutting mechanism 2 and having a certain curvature. When the chip baffle 10 is mounted on the trimming tool, the curvature of the end of the chip baffle 10 away from the housing is greater than the curvature of the end of the chip baffle 10 near the housing, and the curvature decreases smoothly from the end of the chip baffle 10 away from the housing to the end near the housing. By making the chip baffle 10 concave and curved towards the cutting mechanism 2, it can, on the one hand, envelop and deflect the movement trajectory of the chips when the cutting mechanism 2 throws them out, guiding the chips to fall away from the housing 1, the protective plate 11, the gripping part 121 of the first handle 12, and the area where the second handle 13 is located, thereby reducing the risk of chips directly impacting the operator and their gripping parts; on the other hand, the arc-shaped structure is better than a flat baffle in reducing the rebound and splash range of chips, allowing more chips to slide down along the concave surface to the lower or lateral areas away from the operating area, which helps to keep the housing 1 and the surrounding area relatively clean, improving the safety and comfort of operation.

[0294] The technical solution provided in Embodiment 7 of the present invention is as follows: See Figures 1 to 3The trimming tool includes a housing 1, a cutting mechanism 2, an indicating mechanism 4, and a control mechanism 8. The housing 1 has a first housing 141 with a first handle 12 and a second housing 151 with a second handle 13. The first housing 141 moves relative to the second housing 151 between a first position and a second position. The cutting mechanism 2 is mounted on the housing 1 and has a cutting plane S0. The indicating mechanism 4 is mounted on the housing 1 and configured to indicate the deflection state of the cutting plane S0 relative to a reference plane. The control mechanism 8 is mounted on the housing 1 and configured to: in a first position, control mechanism 8 control indicating mechanism 4 to indicate the deflection state of the cutting plane S0 relative to the reference plane in a first preset area; and in a second position, control mechanism 8 control indicating mechanism 4 to indicate the deflection state of the cutting plane S0 relative to the reference plane in a second preset area.

[0295] It should be noted that the first position can be defined as the position where the first housing 141 is in a horizontal posture relative to the second housing 151, and the direction corresponding to this horizontal posture is taken as the reference direction; the second position can be defined as the posture position where the first housing 141 is deflected to the left relative to the second housing 151 (for example, deflected by about 90° relative to the reference direction); the third position can be defined as the posture position where the first housing 141 is deflected to the right relative to the second housing 151 (for example, deflected by about 90° relative to the reference direction); wherein, the left and right sides are defined with reference to the user's normal grip and facing the cutting mechanism 2.

[0296] In some embodiments of this disclosure, the trimming tool further includes a horizontal detection mechanism 5. The horizontal detection mechanism 5 is housed within the housing 1 and configured to detect the deflection state of the cutting plane S0 relative to a reference plane and output a detection signal. A control mechanism 8 is electrically connected to the horizontal detection mechanism 5 and the indicating mechanism 4, and is configured to, in a first position or a second position, control the indicating mechanism 4 to issue a first display signal based on a first detection signal detected by the horizontal detection mechanism 5, and control the indicating mechanism 4 to issue a second display signal based on a second detection signal detected by the horizontal detection mechanism 5.

[0297] For example, when the first housing 141 is in a first position (horizontal posture, reference direction 0°) relative to the second housing 151, the control mechanism 8 sets the display area of ​​the indicating mechanism 4 to a first preset area: when the detection value meets the condition corresponding to the first threshold (e.g., when the deflection angle is within 5°), a first display signal is displayed in the first preset area (e.g., lighting up one LED); when the detection value meets the condition corresponding to the second threshold (e.g., when the deflection angle is within 5° to 10°), a second display signal is displayed in the first preset area (e.g., lighting up two LEDs); when the detection value meets the condition corresponding to the third threshold (e.g., when the deflection angle is within 10° to 15°), a third display signal is displayed in the first preset area (e.g., lighting up three LEDs). The first housing 141 is in a first position (horizontal posture, reference direction 0°) relative to the second housing 151. When the first housing 141 is in the second position (deflected to the left), the control mechanism 8 switches the display area of ​​the indicator mechanism 4 to the second preset area, and displays the first display signal, the second display signal, and the third display signal according to the same display rules as the first preset area. Optionally, when the first housing 141 is in the third position (deflected to the right) relative to the second housing 151, the control mechanism 8 switches the display area of ​​the indicator mechanism 4 to the third preset area, and similarly displays the first signal, the second signal, and the third signal according to the threshold segmentation rules. Thus, regardless of whether the first housing 141 is in a horizontal position or a left-right deflected position relative to the second housing 151, the operator can intuitively obtain the deflection prompt information of the cutting plane S0 within the preset area corresponding to the current position.

[0298] The technical solution provided in Embodiment 8 of the present invention is as follows: See Figures 1 to 3 The trimming tool includes a housing 1, a cutting mechanism 2, an indicating mechanism 4, and a control mechanism 8. The housing 1 has a first housing 141 with a first handle 12 and a second housing 151 with a second handle 13. The first housing 141 moves between a first position and a second position relative to the second housing 151. The cutting mechanism 2 is disposed on the housing 1 and has a cutting plane S0. The indicating mechanism 4 is disposed on the housing 1 and is configured to indicate the deflection state of the cutting plane S0 relative to a reference plane. The control mechanism 8 is disposed on the housing 1 and is configured to control the indicating mechanism 4 to indicate the cutting plane S0 relative to the reference plane when the first housing 141 is in either the first position or the second position relative to the second housing 151.

[0299] In use, the cutting mechanism 2 operates under drive and forms a cutting plane S0. A detection mechanism, housed within the housing 1, detects the deflection state of the cutting plane S0 relative to the reference plane and outputs a detection signal corresponding to the deflection state. The control mechanism 8 receives this detection signal, generates control commands based on the deflection state represented by the detection signal, and then drives the indicating mechanism 4 to output display information corresponding to the current deflection state. This allows the operator to know the real-time deflection of the cutting plane S0 relative to the reference plane and adjust their working posture accordingly.

[0300] It should be noted that, in this embodiment, the control mechanism 8 controls the indicating mechanism 4 based on the deflection state of the cutting plane S0 relative to the reference plane, and not on the relative position of the first housing 141 relative to the second housing 151. Therefore, regardless of whether the first housing 141 rotates relative to the second housing 151, and regardless of whether the first housing 141 is in either the first or second position, the indicating mechanism 4 can display the deflection state normally and continuously, avoiding display interruptions, misalignments, or inconsistent indicating logic caused by the relative rotation of the housing 1, thereby improving the reliability and usability of the deflection prompt. It should be understood that the application of this invention is not limited to the detailed structure and arrangement of the components proposed in this invention. This invention can have other embodiments and can be implemented and performed in various ways. The foregoing variations and modifications fall within the scope of this invention. It should be understood that the invention disclosed and defined in this invention extends to all alternative combinations of two or more individual features mentioned or apparent in the text and / or drawings. All these different combinations constitute multiple alternative aspects of the invention. The embodiments described in this invention illustrate the best known mode for carrying out the invention and will enable those skilled in the art to utilize the invention.
