Description

Technical Field

[0001] This utility model relates to a long-handled power tool, and more particularly to a long-handled power tool with a compact spatial layout. Background Technology

[0002] Currently, the components that occupy most of the structural space in the rear housing of long-handled power tools on the market are the battery pack and the controller. If the controller is placed horizontally between the connecting rod and the electrode holder, it will cause a significant increase in the length of the housing. If the battery pack is placed vertically, it will cause an increase in the height of the housing. Improper arrangement of the battery pack and the controller will reduce the internal space of the rear housing.

[0003] In view of the above problems, it is indeed necessary to provide a power tool to overcome the shortcomings of the prior art. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a long-handled power tool with a compact spatial layout.

[0005] The present invention addresses the existing technical problems by adopting the following technical solution: a long-handled power tool, comprising a housing, a receiving cavity enclosed by the housing, a connecting component connected to the housing and extending along a first axis, a control component located within the receiving cavity, and a power supply component electrically connected to the control component; characterized in that: the control component extends along a second axis, the power supply component is connected to the housing along a third axis, and the first axis, the second axis, and the third axis intersect each other.

[0006] A further improvement is that the third axis extends through the control component.

[0007] A further improvement is that the housing includes a first housing extending along the first axis, a second housing extending along the second axis, and a third housing extending along the third axis, wherein the first housing, the second housing, and the third housing constitute an integral structure.

[0008] A further improvement is that the intersection points of the third axis, the second axis, and the first axis are located within the area enclosed by the second shell and the third shell.

[0009] A further improvement is as follows: the second housing includes an air inlet and an air outlet disposed opposite to the air inlet, and the control component is located between the air inlet and the air outlet.

[0011] A further improvement is that the third housing is at least partially located above the first housing, and when viewed along the first axis, the third housing at least partially overlaps with the control component.

[0012] A further improvement is as follows: the control component includes a first side facing the power supply component and a second side opposite to the first side. The power supply component is electrically connected to the control component via a cable. The cable is connected to the second side of the control component. When viewed along the first axis, the cable is located in the area where the third housing overlaps with the control component.

[0013] A further improvement is as follows: the long-handled power tool includes a motor assembly, a cable connecting the motor assembly and the control assembly, and a wire clamping plate for fixing the cable. The wire clamping plate is located inside the first housing and is disposed close to the connecting assembly.

[0014] A further improvement is as follows: the connecting component includes a cable routing port for the cable to pass through, and the pressure plate is positioned close to the cable routing port.

[0037] For example, the terms "upper," "lower," "front," and "back" used below, which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of facilitating the description of this utility model and simplifying the description, and do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Please refer to Figure 1 The diagram shows the structure of the long-handled power tool 100 of this utility model. Specifically, the long-handled power tool 100 of this utility model can be a lawnmower, brush cutter, or branch saw, etc. The power tool 100 includes a working component 10, a connecting component 20 connected at one end to the working component 10, a main handle 30 connected to the other end of the connecting component 20, and an auxiliary handle 40 disposed on the connecting component 20.

[0039] The working component 10 is located at the front end of the power tool, and the working component 10 includes a cutting component, such as a grass trimmer or brush cutter blade, etc. The working component 10 also includes a motor component for driving the cutting component and a fan component (not shown) for cooling the motor component.

[0040] The motor assembly is located inside the front end housing and is fixed to the base of the front end housing via a motor stator bracket. In other embodiments, the front end housing also includes a reduction gear assembly that is connected to the motor assembly in a transmission manner. The motor stator bracket is directly connected to the reduction gear assembly, and the reduction gear assembly is directly fixed to the base of the front end housing via screws. That is, the motor stator bracket is indirectly fixed to the front end housing. Therefore, whether the motor stator bracket is directly or indirectly fixed to the front end housing, it is within the protection scope of this utility model.

[0041] The front end housing of the long-handled power tool 100 is a split design, consisting of an upper housing and a lower housing, which are fixedly connected by screws. The motor assembly is located in the cavity enclosed by the two housings. When the user assembles the front end housing, the upper and lower housings fixed by screws are first separated, and then the motor stator bracket is placed into the cavity from the open end of the lower housing. The motor stator bracket is then fixed to the bottom of the lower housing by screwing downwards.

[0042] In an embodiment of this utility model, the long-handled power tool further includes a fan assembly located inside the front head shell. The fan assembly is located above the motor assembly and connected to the drive shaft of the motor assembly. The fan assembly rotates together with the drive shaft. When the motor assembly rotates at high speed, the fan assembly is used to dissipate heat from the motor assembly. Specifically, the fan assembly is an axial fan, which is used to draw cooling airflow to the top of the motor assembly to dissipate heat from top to bottom inside the motor assembly.

[0043] In addition, a centrifugal fan is provided between the front end head shell and the cutting assembly to exhaust the cooling airflow inside the front end head shell outside the shell; in other embodiments, the centrifugal fan blades for exhausting the cooling airflow are located on the top of the shell of the cutting assembly, and the cutting assembly is connected to the drive shaft of the motor assembly. Therefore, when the motor assembly rotates at high speed, the centrifugal fan blades on the cutting assembly also rotate together to exhaust the cooling airflow from the front end head shell. The above situation also falls within the protection scope of this utility model.

[0044] The connecting assembly 20 includes a first connecting tube and a second connecting tube. The connecting assembly 20 extends along a first axis L1. The first connecting tube is connected to the working assembly 10, and the second connecting tube is connected to the main handle 30. A connector is provided between the first connecting tube and the second connecting tube to connect the two connecting tubes. The two connecting tubes can be folded to facilitate the storage of the power tool.

[0045] The first connecting pipe of the connecting assembly 20 is connected to the front end housing of the working assembly 10. The front end housing includes an outwardly extending connecting portion. The first connecting pipe is connected to the connecting portion. In addition, several air inlets are provided below the first connecting pipe to allow external airflow to enter the first connecting pipe and then enter the front end housing through the connecting portion to cool the motor assembly inside the front end housing.

[0046] The auxiliary handle 40 is located on the second connecting tube, and a horizontal protective bar is also fitted on the left side of the auxiliary handle to prevent injury to the user during use. The auxiliary handle 40 is designed as a D-shaped handle, but in other embodiments it can also be a U-shaped handle, etc. The auxiliary handle 40 is fixed to the second connecting tube of the connecting assembly 20 by screws or other fasteners to assist the user in operation and reduce the user's workload.

[0047] The power tool also includes a main handle 30, which is located at the rear end of the auxiliary handle 40. The main handle 30 and the auxiliary handle 40 cooperate to allow the user to operate with both hands during use, avoiding tilting or loss of control of the power tool caused by unilateral force. In other embodiments, the auxiliary handle 40 can also be adjusted in angle to control the cutting range of the cutting blade or straw rope. The position where the auxiliary handle 40 contacts the connecting component 20 is also provided with shock-absorbing or cushioning material to improve the operating stability of the power tool 100.

[0048] The long-handle power tool 100 also includes a control component 50 and a power supply component 60 located at the rear end of the connection component 20. The control component 50 is vertically placed inside the rear end housing of the long-handle power tool 100, and the power supply component 60 is obliquely mounted on the mounting part 61 of the rear end housing. The power supply component 60 and the control component 50 are connected by a cable 80.

[0049] Please see Figure 2 As shown, the main handle 30 of the long-handle power tool 100 includes a housing 31 and a receiving cavity 32 enclosed by the housing 31. The connecting component 20 is connected to the housing 31, the control component 50 is located in the receiving cavity 32, and the power supply component 60 is electrically connected to the control component 50.

[0050] In this embodiment, the central axis of the control component 50 is defined as the second axis L2, and the central axis of the power supply component 60 is defined as the third axis L3. The control component 50 extends along the second axis L2, and the power supply component 60 is connected to the housing 31 along the third axis L3. The first axis L1, the second axis L2, and the third axis L3 intersect each other to make the internal space layout of the housing 31 more compact.

[0051] The third axis L3 extends through the control component 50, meaning the control component 50 is located along the extension direction of the third axis L3. The dimension of the control component 50 in the radial direction perpendicular to the first axis L1 is smaller than the dimension of the control component 50 in the second axis L2, meaning the dimension of the control component 50 in the width direction is smaller than the dimension of the control component in the height direction.

[0052] The control component 50 is placed within the receiving cavity 32 along the second axis L2. In this embodiment, the second axis L2 is vertical. In other embodiments, the second axis L2 may be tilted at a certain angle relative to the vertical direction. The fact that the control component 50 is positioned along the second axis L2 reduces the length of the housing 31 along the first axis L1.

[0053] Please see Figures 2 to 3 As shown, the housing 31 includes a first housing 311 extending along the first axis L1, a second housing 312 extending along the second axis L2, and a third housing 313 extending along the third axis L3. The first housing 311, the second housing 312, and the third housing 313 are configured as an integral structure, that is, the internal spaces of the first housing 311, the second housing 312, and the third housing 313 are interconnected to facilitate a compact arrangement of the internal spaces.

[0054] The first housing 311 includes a gripping area for user operation, and the first housing 311 includes a trigger assembly 33 that protrudes at least partially from the first housing 311, a locking assembly 34 for limiting the movement of the trigger assembly 33, and a micro switch 35 disposed near the trigger assembly 33.

[0055] The trigger assembly 33 is used for user operation to start the machine, and the locking assembly 34 is used to prevent the user from accidentally triggering the trigger assembly 33 and causing the machine to start unexpectedly. That is, during use, the user must first release the locking assembly 34 from the trigger assembly 33 before starting the machine, to ensure the user's safety.

[0056] In this embodiment, the locking component 34 and the trigger component 33 are mechanically self-locking, and the locking component 34 is a sliding structure; in other embodiments, the locking component 50 may also be a push-button structure, usually located near the switch trigger. In this utility model, the locking form of the locking component 34 is not limited, that is, any structure that can lock the trigger component 33 falls within the protection scope of this utility model.

[0057] The second housing 312 is at least partially located below the first housing 311, and the second housing 312 communicates with the first housing 311. The second housing 312 extends downward from the first housing 311 along the second axis L2 and protrudes downward from the edge of the first housing. The control component is at least partially located in the portion of the second housing that protrudes from the first housing.

[0058] When the machine is placed horizontally on the ground, the second housing is configured to protrude from the first housing, that is, the second housing is in direct contact with the ground. In other embodiments, a support is provided at the position where the second housing contacts the ground, making the machine more stable and reliable when placed horizontally.

[0059] Viewed along the first axis L1, the second housing 312 is located between the first housing 311 and the third housing 313. Because the second housing 312 protrudes downward, it is closer to the ground than the third housing 313. The power supply component 60 is obliquely connected to the mounting portion 316 of the third housing 313 along the third axis L3. The second housing 312 is closer to the ground than the power supply component 60, that is, the distance between the power supply component 60 and the ground is greater than the distance between the second housing 312 and the ground.

[0060] When the power tool 100 is accidentally dropped, because the second housing 312 protrudes from the first housing 311 and is closer to the ground than the power supply component 60, the second housing 312 contacts the ground first, preventing the power supply component 60 from contacting the ground and being damaged, thus further protecting the power tool. Therefore, designing the second housing 312 to protrude from the first housing 311 is beneficial for protecting the power supply component 60 and the power tool 100, and increasing the service life of the power tool 100.

[0061] The first housing 311 is substantially perpendicular to the second housing 312. The control component 50 is placed inside the second housing 312 along the second axis L2, that is, the control component 50 is placed vertically in the part of the second housing 312 located below the first housing 311. Compared with other embodiments where the control component 50 is placed horizontally inside the housing, placing the control component 50 vertically helps to reduce the spatial dimensions of the housing 31 in the length direction.

[0062] The third housing 313 is located at the rear end of the second housing 312 and at least partially above the first housing 311, with the second housing 312 situated between the first housing 311 and the third housing 313 along the first axis L1. Viewed along the first axis L1, the third housing 313 at least partially overlaps with the control assembly 50.

[0063] The third housing 313 is inclined relative to the first housing 311 and the second housing 312. The third housing 313 includes a mounting portion 316 for the power supply component 60 to be inserted into, and the power supply component 60 is mounted to the mounting portion 316 along the third axis L3.

[0064] The intersection points of the third axis L3, the second axis L2, and the first axis L1 are located within the area enclosed by the second housing 312 and the third housing 313. Specifically, the intersection point of the first axis L1 and the second axis L2 is located above the control component 50 and within the area between the second housing 312 and the third housing 313.

[0065] The angle β between the first axis L1 and the second axis L2 is 90°, that is, the first axis L1 and the second axis L2 are set perpendicularly. In other embodiments, the control component 50 is set at a certain angle relative to the second axis L2, that is, the angle between the first axis L1 and the second axis L2 is an acute angle. This setting of the control component 50 can shorten the size of the control component 50 in the height direction, and further make the spatial layout within the second housing 312 more compact.

[0066] The intersection of the first axis L1 and the third axis L3 is located inside the third housing 313 and close to the power supply component 60. In this embodiment, the angle γ between the first axis L1 and the third axis L3 is an acute angle, that is, the third housing 313 is inclined relative to the first housing 311. The power supply component 60 inserted into the third housing 313 is also arranged along the third axis L3. Compared with the power supply component 60 being placed vertically in other embodiments, tilting the power supply component 60 at a certain angle is beneficial to reducing the size of the housing 31 in the height direction.

[0067] The intersection of the second axis L2 and the third axis L3 is located inside the second housing 312 and close to the control component 50. The included angle α between them is an acute angle. The projections of the control component 50 and the power supply component 60 on the second axis L2 at least partially overlap. The power supply component 60 is at least partially located above the control component 50, and the control component 50 is disposed close to the electrode holder 61 of the power supply component 60.

[0068] Please see Figure 3 As shown, the long-handled power tool 100 also includes a motor assembly, a cable 80 connecting the motor assembly and the control assembly 50, and a wire clamping plate 70 for fixing the cable 80. The wire clamping plate 70 is located inside the first housing 311 and is disposed close to the connecting assembly 20.

[0069] The motor assembly is located within the working assembly 10, and the cable 80 of the motor assembly passes through the hollow channel of the connecting assembly 20. The second connecting tube of the connecting assembly 20 extends at least partially into the housing 31 of the main handle 30, and then the cable 80 extends into the housing 31 to connect to the control assembly 50, thereby realizing the electrical connection between the motor assembly and the control assembly.

[0070] In this embodiment, the motor stator bracket includes an air outlet and a cable groove at the bottom. The cable 80 passes through the air outlet of the stator bracket and exits the front end housing through the cable groove, extending to the hollow channel of the connecting assembly 20. By providing a cable groove on the stator bracket for the cable 80 to pass through, the cables of the motor assembly are easily organized, preventing them from becoming tangled. The air outlet and the cable groove together form a cable routing channel, making the spatial layout more compact.

[0071] The connection assembly 20 includes a cable tray 21 for the cable 80 to enter. The cable tray 21 is located at one end of the connection assembly 20 extending into the housing 31. The cable tray 21 is used for the cable 80 to pass through in order to electrically connect the motor assembly and the control assembly 50.

[0072] The pressure plate 70 is disposed near the cable routing port 21 and is used to fix and press the cable 80 that passes through the cable routing port 21. The pressure plate 70 includes a groove through which the cable 80 can pass and a fixing part for fixing it to the housing 31. The pressure plate 70 and the cable routing port 21 are both located inside the first housing 311 and are disposed near the connecting assembly 20. The pressure plate 70 is used to fix and press the cable 80 to prevent the cable 80 from being distributed messily in the housing 31, which would result in an uncompacted internal space layout of the receiving cavity 32.

[0073] The cable 80 enters the receiving cavity 32 from the cable routing port 21 and is fixed by the clamping plate 70 located near the cable routing port 21. This prevents the cable 80 from being scattered messily in the receiving cavity 32, which would reduce the usable space in the receiving cavity 32. By setting the clamping plate 70, the portion of the cable 80 that enters the receiving cavity 32 from the cable routing port 21 can be neatly and orderly fixed to the vicinity of the cable routing port 21, making the spatial layout in the receiving cavity 32 more compact.

[0074] The wire clamping plate 70 and the cable routing port 21 are both located inside the first housing 311, and the wire clamping plate 70 is located between the cable routing port 21 and the control component 50. The first housing 311 also includes a micro switch 35 electrically connected to the control component 50 via the cable 80. The micro switch 35 is located close to the trigger assembly 33 and is mechanically connected to the trigger assembly 33. When the trigger assembly 33 is pressed by the operator, the trigger assembly 33 abuts against the micro switch 35 to start the machine.

[0075] The control component 50 includes a first side 51 facing the power supply component 60 and a second side 52 opposite to the first side 51. The first side 51 is located close to the power supply component 60 and has several heat dissipation fins for heat dissipation of the control component 50. The cable 80 is connected to the second side 52, which is located close to the wire clamping plate 70.

[0076] The micro switch 35 is connected to the second side 52 of the control component 50 via the cable 80. The control component 50 is disposed inside the second housing 312 and perpendicular to the first housing 311, such that the second side 52 of the control component 50 faces the wire plate 70 and the micro switch 35. This facilitates the connection of the cable 80 to the wire of the micro switch 35 to the second side 52 of the control component 50, thereby reducing the cable length and saving costs to a certain extent.

[0077] The power supply component 60 is wired to the control component 50 via a cable 80. Specifically, the power supply component 60 includes an electrode holder 61, which is disposed near the first side 51 of the control component 50. The electrode holder 61 is provided with a wiring groove for the cable 80 to connect. The cable 80 connects the electrode holder 61 to the control component 50 and is also connected to the second side 52 of the control component 50. When viewed along the first axis L1, the cable 80 is located in the area where the third housing 313 overlaps with the control component 50.

[0078] The cable 80 is connected to the second side 52 of the control component 50. Since the first side 51 of the control component 50 is located close to the electrode base 61, the cable 80 needs to be routed from above the control component 50 to the second side 52 to connect to the second side 52. This effectively utilizes the space above the control component 50, making the layout of the power tool 100 more compact.

[0079] The control component 50 is placed vertically inside the second housing 312, and the second housing 312 is located between the power supply component 60 and the micro switch 35. That is, the control component 50 is located between the power supply component 60 and the micro switch 35. The electrode holders 61 of the micro switch 35 and the power supply component 60 are connected to the second side 52 of the control component 50 through the cable 80. The placement of the control component 50 is conducive to the connection of the cable 80, making the wiring arrangement in the receiving cavity 32 smoother and saving the internal space of the housing 31.

[0080] The second housing 312 includes an air inlet 314 and an air outlet 315 disposed opposite to the air inlet 314, and the control component is located between the air inlet 314 and the air outlet 315.

[0081] In this embodiment, when the long-handled power tool 100 is in operation, the motor assembly and fan assembly located at the front end of the tool 100 rotate together. The fan assembly is used to dissipate heat from the motor assembly. Under the negative pressure of the front working component, a small portion of the external airflow enters the housing 31 from the air inlet 314 and flows through the connecting assembly 20 to the front head shell of the working component 10. The other portion flows out of the housing 31 from the air outlet 315. The control component 50 is located between the air inlet 314 and the air outlet 315 and dissipates heat on its own. In other embodiments, a fan is provided near the control component 50 to dissipate heat from the control component 50.

[0082] The connecting component 20 has several ventilation holes near the working component 10. The connecting component 20 has a hollow channel, and the cooling airflow connects the working component 10 and the receiving cavity 32 of the housing 31.

[0083] When the long-handle power tool 100 is in operation, the axial fan connected to the drive shaft of the motor assembly rotates with the drive shaft, generating negative pressure. At this time, external airflow enters the hollow channel through several ventilation holes on the connecting assembly 20 and enters the front head shell. Under the action of the axial fan, the airflow is drawn to the top of the motor assembly and enters the interior of the motor assembly to cool it. Because a baffle plate protrudes from the motor stator bracket along the drive shaft direction, the cooling airflow entering the motor assembly does not flow out from the outer periphery of the stator bracket and is discharged from the front head shell by a centrifugal fan located between the front head shell and the cutting assembly to dissipate heat from the motor assembly.

[0084] Under negative pressure, external airflow enters the receiving cavity 32 through the air inlet 314. Part of it flows along the hollow channel in the connecting component 20 to the working component 10, and part of it flows out of the receiving cavity 32 through the air outlet 315, thereby dissipating heat from the control component 50. In other embodiments, the second housing 312 also includes a fan for dissipating heat from the control component 50. This embodiment also falls within the protection scope of this utility model.

[0085] Currently, professional lawnmowers on the market have high power, and the motor assembly is generally located inside the rear housing, which greatly reduces the risk of grass clippings and other debris getting tangled in the motor output shaft and causing stalling and overheating. However, for ordinary household users, professional lawnmowers are overkill, with excessive weight, vibration, and noise.

[0086] In comparison, placing the drive motor at the front inside the working head not only allows for a highly integrated design of the motor, reduction gear or direct drive structure, and trimming head, resulting in strong power while improving machine vibration and noise, but also significantly reduces the weight of the transmission system, thereby reducing the machine's own weight and improving operational comfort. Furthermore, the development and manufacturing cost of front-mounted motors is relatively low and they have a certain market competitiveness. Therefore, placing the motor assembly at the front inside the front head shell also makes the overall layout of the machine more reasonable and the weight of the machine more balanced.

[0087] Front-motor lawnmowers are generally targeted at home users. Therefore, compared to the high power and strong cutting capabilities of professional lawnmowers, lightweight portability, aesthetics, and comfort are the main advantages of front-motor lawnmowers and the main goals of their product structure design. A front-motor lawnmower generally consists of a battery pack, rear housing assembly, rear handle assembly, connecting rod assembly, front housing assembly, and cutting head.

[0088] Comparatively, the most important and heaviest components of the machine are the motor, trimmer head, controller, connecting rod, and battery pack. The trimmer head and motor are mainly located in the head section, with a compact transmission structure. The controller, connecting rod, and battery pack, however, are relatively dispersed. In addition, components such as electrode holders, switches, triggers, and wiring harnesses, installed inside the rear housing and rear handle assembly, are also quite scattered. Therefore, the key is to achieve a compact arrangement of components within the rear housing and rear handle assembly while ensuring a reasonable and comfortable weight distribution that conforms to ergonomic principles.

[0089] The long-handle power tool 100 of this utility model, specifically a lawnmower or brush cutter, features an optimized design for the internal space layout of the main handle 30 located at the rear of the tool. Currently, the rear housing of commonly available front-motor lawnmowers includes an electrode holder, battery pack, and controller, while the main handle includes a switch, trigger, and wiring harness assembly. It is worth noting that the battery pack and controller occupy most of the structural space in the rear housing.

[0090] In other embodiments, placing the controller at the bottom of the connecting rod increases the height of the front end of the rear housing; while placing the controller horizontally between the connecting rod and the electrode holder significantly increases the length of the housing. Therefore, the arrangement of the battery pack and the controller is a key factor in determining the compactness of the rear housing structure.

[0091] This invention integrates the rear housing arrangement structure of existing 12V and above handheld lawnmowers / high branch saws / brush cutters, and proposes a new controller arrangement that can achieve a more compact structural layout.

[0092] The control component 50 of this utility model is located between the electrode base 61 of the power supply component 60 and the wiring port 21 of the connection component 20. The control component 50 is placed vertically, that is, perpendicular to the extension direction of the connection component 20. In other words, the first axis L1 of the connection component 20 is perpendicular to the second axis L2 of the control component. The dimension of the control component 50 in the height direction is larger than the dimension of the control component 50 in the width direction, which helps to save the internal layout space of the housing 31.

[0093] In this invention, the power supply component 60 is obliquely mounted behind the control component 50, and the angle between the third axis L3 where the power supply component 60 is located and the second axis L2 where the control component 50 is located is an acute angle. Compared to the vertical placement of the power supply component 60 in other embodiments, obliquely positioning the power supply component 60 at the rear end of the long-handled power tool 100 helps to shorten the height dimension of the housing 31, making the internal space layout of the housing 31 more compact.

[0094] To ensure the reliability of the power supply component 60 installation, its height dimension cannot be excessively reduced. Therefore, for the installation direction of the control component 50, the dimension in the height direction of the housing is greater than the dimension in the width direction, which can make full use of the redundant space created by the power supply component installation structure. In addition, the power supply component 60 is inclined relative to the control component 50, which can save structural space in the length direction of the housing and facilitate smooth wiring within the housing.

[0095] Typically, the wiring harnesses on the control components are mainly used to connect components such as electrode holders, motors, and control switches. Therefore, arranging the control components between the electrode holders and the motor can further shorten the length of each wiring harness, reducing wiring harness costs and saving wiring space in the housing to some extent. Please refer to [link / reference]. Figures 1 to 3 As shown, the housing 31 of the main handle 30 of the long-handle power tool 100 is simple and beautiful in general, and the internal space is reasonably and compactly arranged.

[0096] In this embodiment, the control component 50 is arranged between the electrode base 61 of the power supply component 60 and the micro switch 35 that controls the start and stop of the trigger component 33. This can further shorten the length of the cable 80, which not only reduces the cost of the cable, but also saves the wiring space inside the housing 31 to a certain extent.

[0097] In this utility model, the control component 50 of the long-handle power tool 100 extends along the second axis L2, the main handle housing extends along the axis L1, and the power supply component extends along the third axis L3, which intersect each other, making the spatial layout inside the main handle housing more compact.

The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Those skilled in the art will readily understand that any modifications or changes made to the above embodiments without departing from the spirit and scope of this utility model should still be covered by the claims of this utility model.
