Description

Technical Field

[0001] This application relates to the field of power tool technology, and more particularly to a power tool. Background Technology

[0002] A tapping machine is a specialized piece of equipment used to process internal threads in workpieces. It is widely used in various fields such as machining, automotive manufacturing, aerospace, construction, and electronics. The main function of a tapping machine is to use a tap to cut within the hole of a workpiece to form threads. With the advancement of industrial automation and intelligence, the functionality and efficiency of tapping machines have been significantly improved.

[0003] However, various safety hazards may arise during the actual use of tapping machines. For example, when manually operating a tapping machine, the operator needs to directly contact or approach the high-speed rotating tap, which can easily lead to hand injuries or cuts. Another example is that if chips from a broken tap are ejected during the tapping process, it can cause serious injury to the user. Therefore, improving the safety of tapping machines is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application provides an electric tool for improving the safety performance of electric tools.

[0005] This application provides an electric tool and its control method to improve the safety performance of the electric tool.

[0006] In a first aspect, this application provides a power tool, comprising: a main body structure, the main body structure including a housing, a drive mechanism disposed therein, a first groove provided on a first surface of the housing for placing a first tool attachment, the drive mechanism for driving the first tool attachment to move; a first component, spliced ​​with the housing, the first component including a first channel; wherein, the first tool attachment can move within the first channel; when the first tool attachment contacts the surface of a workpiece, a first force applied by a user to the housing acts on the housing, the housing and the first component move axially in the housing, so that the first component contacts the surface of the workpiece.

[0007] In this embodiment, the power tool may be at least one of a tapping machine, an electric screwdriver, or an electric drill. The first tool accessory can be understood as the cutting head currently mounted on the power tool, such as a tap or a drill bit.

[0008] In the technical solution of this application, a first channel is provided in the first component of the power tool, and a first tool attachment installed on the power tool can move within the first channel. When the first tool attachment contacts the workpiece surface, a first force applied by the user to the housing of the power tool acts on the housing, causing the housing and the first component to move axially within the housing, so that the first component contacts the workpiece surface. Thus, when the user uses the power tool, even when the first component is in contact with the workpiece surface, direct contact or proximity to the first tool attachment can be avoided, effectively improving the safety performance of the power tool. For example, taking a tapping machine as an example, and a tap as an example, when the user manually operates the tapping machine, because the first component is in contact with the workpiece surface, the tap moves within the first channel formed by the first component, preventing tap breakage and potential hand injury to the user, and preventing the workpiece from being thrown out by the high-speed rotating tap due to insecure fixation, thus preventing injury to the user.

[0009] In one possible design, when the first component contacts the workpiece surface, the first tool attachment is perpendicular to the workpiece surface. This design ensures that the first tool attachment is perpendicular to the workpiece surface, effectively improving the perpendicularity and concentricity of the first tool attachment in the workpiece machining process, thereby significantly enhancing the performance of the power tool. For example, taking a tapping machine as an example, and a tap as an example, the technical solution of this application can improve the perpendicularity and concentricity of the tap in the workpiece machining process, reducing the probability of tap breakage during machining, thus enabling the tapping machine to machine small-diameter threads. Furthermore, the improved perpendicularity and concentricity of the first tool attachment in the workpiece machining process when the first component contacts the workpiece surface further enhances the tapping quality and success rate of the tapping machine.

[0010] In one possible design, when the first tool attachment processes the workpiece, the housing and the first component are relatively stationary with respect to the workpiece surface. A second force and / or a third force acts on the drive mechanism, causing the drive mechanism and the first tool attachment to move axially in the housing. The second force is generated by the second component in the drive mechanism, and the third force is applied by the user to the third component in the main body mechanism. In this design, the force generated by the second component in the drive mechanism (i.e., the second force) acts on the drive mechanism, serving as the feed pressure for the first tool attachment to process the workpiece, enabling the drive mechanism and the first tool attachment to move axially in the housing. The force generated by the second component in the drive mechanism is stable, meaning the feed pressure of the first tool attachment to the workpiece is stable, whereas the feed pressure directly provided by the user to the first tool attachment is unstable. Therefore, the method in this application, which uses the force generated by the second component in the drive mechanism to provide the feed pressure of the first tool attachment to the workpiece, can further improve the tapping quality and success rate of the tapping machine compared to the technical solution where the user directly provides the feed pressure.

[0011] Alternatively, the force (i.e., the third force) applied by the user to the third component in the main body mechanism acts on the drive mechanism, which can cause the drive mechanism and the first tool attachment to move axially in the housing. That is, the user provides the feed pressure of the first tool attachment for machining the workpiece, so that the user can flexibly use power tools to machine the workpiece.

[0012] Alternatively, the force generated by the second component in the drive mechanism (i.e., the second force) and the force applied by the user to the third component in the main body mechanism (i.e., the third force) work together on the drive mechanism, allowing the drive mechanism and the first tool attachment to move axially within the housing. The force generated by the second component in the drive mechanism is stable, while the force applied by the user to the third component in the main body mechanism is flexibly adjustable. That is, in addition to providing a stable feed pressure for the first tool attachment to process the workpiece, the user can further adjust the feed pressure of the first tool attachment to process the workpiece according to actual needs. This not only improves the tapping quality and success rate of the tapping machine to a certain extent, but also provides users with the flexibility to use power tools, allowing them to flexibly adjust the feed pressure of the first tool attachment to process the workpiece according to different processing requirements.

[0013] In one possible design, the drive mechanism and the first tool attachment stop moving when the first tool attachment reaches the target machining depth of the workpiece. This design, where the drive mechanism and the first tool attachment stop moving when the first tool attachment reaches the target machining depth of the workpiece, effectively prevents the first tool attachment from mistakenly machining the workpiece.

[0014] In one possible design, when the first tool attachment finishes machining the workpiece, the drive mechanism and the first tool attachment move axially in the housing.

[0015] In one possible design, the main body mechanism further includes a depth sensor for acquiring the machining depth of the workpiece by the first tool attachment. In this design, by incorporating a depth sensor into the main body mechanism of the power tool, the power tool can measure the machining depth of the workpiece by the first tool attachment, thereby enabling precise control of the machining depth and meeting the user's machining needs under different working conditions. For example, taking a tapping machine as an example, and a tap as an example, in addition to measuring the machining depth of the tap on the workpiece, the tapping machine also supports drilling blind holes in the workpiece.

[0016] In one possible design, when the first tool attachment is replaced with a second tool attachment or when the machining start plane of the workpiece changes, the depth sensor initializes the workpiece machining depth obtained from the first tool attachment to a first value. In this design, when the power tool changes tool attachments or the workpiece machining start plane changes, the depth sensor's measurement value can be initialized promptly, thereby effectively improving the depth sensor's measurement accuracy.

[0017] In one possible design, the first component includes a support structure comprising N points where the first component contacts the workpiece surface. In this design, by incorporating the support structure into the first component of the power tool, the stability of the first component is improved when it contacts the workpiece surface, thereby ensuring that the first tool attachment remains stably perpendicular to the workpiece surface.

[0018] In one possible design, the first component has a telescopic structure disposed within the support structure; alternatively, the first component further includes a first structure connected to the support structure to form the telescopic structure. This design allows the length of the first component to be adjustable, thereby adjusting the depth of workpiece machining by the first tool attachment.

[0019] In one possible design, the relative angle between the first structure and the supporting structure is adjustable. This adjustable angle allows the angle between the first component and the workpiece contact surface to be adjusted, enabling the user to process the workpiece at their desired angle and thus meet diverse processing needs.

[0020] In one possible design, the side of the first component can be made of a transparent or opaque material. The transparent material can be semi-transparent and / or fully transparent. In this design, the first component can be made of a transparent material to facilitate user observation of the operating conditions.

[0021] In one possible design, the contact surface between the first component and the workpiece surface is provided with an anti-slip rubber pad. This design can reduce damage to the workpiece surface caused by the first component.

[0022] In one possible design, the side of the first component can be any of a closed structure, an open-closed structure, or an open structure. In this design, setting the side of the first component as a closed structure can prevent machining debris from splashing; or...

[0023] By setting the side of the first component to an open or closed structure, the first component can be flexibly controlled to form an open or closed structure, making it convenient to clean up machining debris in the first component; or, by setting the side of the first component to an open structure, the user can easily observe the machining conditions.

[0024] In one possible design, a magnet is provided on the first surface of the housing, and the first component is spliced ​​to the housing, including: the first component is spliced ​​to the housing via the magnet; and / or, a snap-fit ​​structure is provided on the first surface of the housing, and the first component is spliced ​​to the housing, including: the first component is spliced ​​to the housing via the snap-fit ​​structure. This design provides multiple ways for the first component to be spliced ​​to the housing.

[0025] In one possible design, the second component is an elastic element, and the second force is the elastic force generated by the elastic element; wherein the elastic element includes a spring or a magnetic elastic element.

[0026] In one possible design, the drive mechanism further includes at least two rails, each of which houses the elastic element. In this design, two guide rails are provided in the drive mechanism to limit the axial rotation of the motor.

[0027] In one possible design, when the elastic element includes a spring, the spring generates the second force under the compression of the drive mechanism and the housing.

[0028] In one possible design, when the elastic element includes a magnetic elastic element, the driving mechanism further includes an electromagnetic coil. The damping and stiffness of the magnetic elastic element vary with the magnetic field strength generated by the electromagnetic coil, thus forming the second force. In this design, the magnetic elastic element can be a magnetorheological elastomer or a magnetorheological fluid.

[0029] In one possible design, the third component is connected to the drive mechanism, or the third component is located independently of the drive mechanism within the main body mechanism. This design provides several implementations of the third component.

[0030] In one possible design, a first control element is provided on the housing for adjusting the operating parameters of the power tool. The operating parameters include at least one of the following: the rotational speed of the first tool attachment, the predetermined depth of machining of the workpiece by the first tool attachment, the direction of machining of the workpiece by the first tool attachment, or the torque of the motor in the drive mechanism. The first control element can be one or more of a knob, button, or switch. This design provides a control element for adjusting the operating parameters of the power tool, allowing the user to flexibly adjust the operating parameters to meet the user's machining needs under different working conditions.

[0031] In one possible design, the housing also includes a second control element for adjusting the function mode of the power tool. The function mode includes at least one of a tapping machine mode, an electric screwdriver mode, or an electric drill mode. The second control element can be one or more of a knob, a button, or a switch. In this design, the power tool has multiple function modes and provides a control element for switching between them, allowing users to flexibly utilize the various functions of the power tool.

[0032] In one possible design, the housing is further provided with a second recess for placing a third tool accessory. The second recess may include one or more recesses, and the third tool accessory may be one or more commonly used tools or accessories. In this design, the second recess on the surface of the drive mechanism's housing allows for the placement of commonly used tools or accessories, facilitating user access and effectively improving the user experience.

[0033] In one possible design, the power tool further includes a human-machine interface (HMI) component, which is used to: receive a first user instruction for adjusting the operating parameters of the power tool; wherein the operating parameters include at least one of the following: the rotational speed of the first tool attachment, the depth of machining of the workpiece by the first tool attachment, the direction of machining of the workpiece by the first tool attachment, or the torque of the motor in the drive mechanism. In this design, by incorporating the HMI component into the power tool, the user can flexibly adjust the operating parameters of the power tool. The HMI component may include, but is not limited to, one or more of a photoelectric module, a voice module, or a text interaction module.

[0034] In one possible design, the human-machine interface component can also be used to: receive a second user instruction, the second user instruction being used to adjust the function mode of the power tool; wherein the function mode includes at least one of a tapping machine mode, an electric screwdriver mode, or an electric drill mode.

[0035] In one possible design, a display screen is provided on the housing. In this design, the display screen is located on the surface of the housing of the drive mechanism, allowing the user to view information such as time information and operating parameters of the power tool.

[0036] In one possible design, the power tool further includes a controller for controlling the opening / closing structure to form an opening or a closed opening when the side of the first component is an opening / closing structure. In this design, the controller can also control the opening / closing structure of the first component to open or close, making the first component suitable for different processing conditions.

[0037] In one possible design, the depth sensor can be an angle sensor, and the main body mechanism also includes a rack and a gear, with the gear meshing with the rack; the gear is connected to a motor in the drive mechanism via the angle sensor, and the rack is connected to the housing.

[0038] In other possible designs, depth sensors can also be implemented using vernier calipers or laser rangefinders.

[0039] In one possible design, the main body mechanism is L-shaped. This design, by arranging the main body mechanism of the power tool in an L-shape, improves the tool's usability and makes it easier for the user to hold.

[0040] In one possible design, the power tool stops working when the user does not touch it. This design provides a safety mechanism that ensures the power tool stops working promptly when the user is not in contact with it, preventing accidental operation. Attached Figure Description

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] It should be understood that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0064] It should also be understood that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or may be connected to an intermediary element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element through an intermediary element.

[0065] The terminology used in this application specification is for the purpose of describing particular embodiments only and is not intended to limit the application. Descriptions using terms such as "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0066] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0067] In the technical solution of this application, a first channel is provided in the first component of the power tool, and a first tool attachment installed on the power tool can move within the first channel. When the first tool attachment contacts the workpiece surface, a first force applied by the user to the housing of the power tool acts on the housing, causing the housing and the first component to move axially within the housing, so that the first component contacts the workpiece surface. Thus, when the user uses the power tool, even when the first component is in contact with the workpiece surface, direct contact or proximity to the first tool attachment can be avoided, effectively improving the safety performance of the power tool. For example, taking a tapping machine as an example, and a tap as an example, when the user manually operates the tapping machine, because the first component is in contact with the workpiece surface, the tap moves within the first channel formed by the first component, preventing tap breakage and potential hand injury to the user, and preventing the workpiece from being thrown out by the high-speed rotating tap due to insecure fixation, thus preventing injury to the user.

[0068] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0069] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of the power tool 1000 provided in this application. The power tool includes a main body 100 and a first component 200. The main body 100 includes a housing 101, and the first component 200 is spliced ​​to the housing 101. The housing 101 is provided with a drive mechanism 1011 and a first groove 1012. The first groove 1012 can hold a first tool attachment 300, and the drive mechanism 1011 can drive the first tool attachment 300 to move. The first component 200 includes a first channel 201, and the first tool attachment 300 can move within the first channel 201.

[0070] In this embodiment, the power tool 1000 may be at least one of a tapping machine, an electric screwdriver, or an electric drill. The first tool attachment 300 can be understood as a cutting head currently mounted on the power tool 1000, and the first tool attachment 300 can be used to process a workpiece. The first tool attachment 300 may be any one of a tap, a drill bit, or a screwdriver bit. The workpiece may be at least one of wood, steel, wall material, or screws.

[0071] In this embodiment of the application, the first tool attachment 300 may process the workpiece in the following ways, including but not limited to:

[0072] State 1, such as Figure 2As shown in (a), the first tool attachment 300 contacts the workpiece surface. At this time, if the user applies a first force to the housing 101, this force will cause the housing 101 and the first component 200 to move axially along the housing 101, thereby bringing the first component 200 into contact with the workpiece surface. With the first component 200 in contact with the workpiece surface, the user can avoid direct contact or proximity to the first tool attachment 300 when using the power tool 1000, thus effectively improving the safety performance of the power tool 1000. For example, if the power tool 1000 is a tapping machine and the first tool attachment 300 is a tap, when the user manually operates the power tool 1000, because the first component 200 is in contact with the workpiece surface, the tap can move within the first channel 201 formed by the first component 200. This can prevent the tap from breaking and injuring the user's hand, and can also prevent the workpiece from being thrown out by the high-speed rotating tap due to insecure fixation, thus preventing injury to the user.

[0073] When the first component 200 contacts the workpiece surface, the first tool attachment 300 is made perpendicular to the workpiece surface, thereby effectively improving the perpendicularity and concentricity of the first tool attachment 300 in machining the workpiece, and thus effectively improving the working performance of the power tool 1000. For example, if the power tool 1000 is a tapping machine and the first tool attachment 300 is a tap, the technical solution of this application can improve the perpendicularity and concentricity of the tap in machining the workpiece, thereby enabling the tapping machine to tap small threads with smaller diameters, and improving the tapping quality and tapping success rate of the tapping machine.

[0074] State 2, such as Figure 2 As shown in (b), the first tool attachment 300 performs machining operations on the workpiece. At this time, the housing 101 and the first component 200 are stationary relative to the workpiece surface, and the first component 200 is in initial contact with the workpiece plane. A second force and / or a third force acts on the drive mechanism 1011, causing the drive mechanism 1011 and the first tool attachment 300 to move axially in the housing 101, so that the first tool attachment 300 performs machining operations on the workpiece. The second force is generated by the second component in the drive mechanism 1011, and the third force is applied by the user to the third component in the main body mechanism 100.

[0075] In one scenario, the force generated by the second component in the drive mechanism 1011 (i.e., the second force) acts on the drive mechanism 1011. This force serves as the feed pressure for the first tool attachment 300 to process the workpiece, enabling the drive mechanism 1011 and the first tool attachment 300 to move axially in the housing 101. The force generated by the second component in the drive mechanism 1011 is stable, meaning the feed pressure of the first tool attachment 300 to process the workpiece is stable. In contrast, the feed pressure directly provided by the user to the first tool attachment 300 to process the workpiece is unstable. Therefore, the method in this application, which uses the force generated by the second component in the drive mechanism 1011 to provide the feed pressure for the first tool attachment 300 to process the workpiece, can further improve the tapping quality and success rate of the tapping machine compared to the technical solution where the user directly provides the feed pressure.

[0076] In another scenario, the force (i.e., the third force) applied by the user to the third component in the main body 100 acts on the drive mechanism 1011, which can cause the drive mechanism 1011 and the first tool attachment 300 to move axially in the housing 101. In other words, the user provides the feed pressure of the first tool attachment 300 to process the workpiece, allowing the user to flexibly use the power tool 1000 to process the workpiece.

[0077] In another scenario, the force generated by the second component in the drive mechanism 1011 (i.e., the second force) and the force applied by the user to the third component in the main body mechanism 100 (i.e., the third force) work together on the drive mechanism 1011, allowing the drive mechanism 1011 and the first tool attachment 300 to move axially within the housing 101. The force generated by the second component in the drive mechanism 1011 is stable, while the force applied by the user to the third component in the main body mechanism 100 can be flexibly adjusted by the user. That is, in addition to providing a stable feed pressure for the first tool attachment 300 to process the workpiece, the user can further adjust the feed pressure of the first tool attachment 300 to process the workpiece according to actual needs. This not only improves the tapping quality and success rate of the tapping machine to a certain extent but also provides the user with flexibility in using the power tool 1000, allowing the user to flexibly adjust the feed pressure of the first tool attachment 300 to process the workpiece according to different processing requirements.

[0078] In the embodiments of this application, the drive mechanism 1011 can be implemented in various ways, such as by one or more of the following methods: spring drive, hydraulic drive, or servo motor drive, either individually or in combination. The embodiments of this application do not impose specific limitations.

[0079] In one possible implementation, the second component can be an elastic element, and correspondingly, the second force is the elastic force generated by the elastic element; wherein the elastic element may include, for example, a spring or a magnetic elastic element. Alternatively, the second component can be other elements capable of generating force, and this application does not impose specific limitations. Optionally, the drive mechanism 1011 further includes at least two tracks, each of which is provided with the aforementioned elastic element. In this way, the axial rotation of the motor in the drive mechanism 1011 can be limited. The following describes how different elastic elements generate elastic force in different cases.

[0080] Case 1: The elastic element includes a spring, which can generate a second force under the compression of the drive mechanism 1011 and the housing 101.

[0081] In scenario 2, the elastic element includes a magnetic elastic element, and the driving mechanism 1011 also includes an electromagnetic coil. Therefore, the damping and stiffness of the magnetic elastic element change with the magnetic field strength generated by the electromagnetic coil, thus forming a second force. The magnetic elastic element can be, for example, a magnetorheological elastomer or a magnetorheological fluid.

[0082] In one possible implementation, the third component can be connected to the drive mechanism 1011, or the third component can be set independently of the drive mechanism 1011 in the main body mechanism 100. Thus, multiple implementations of the third component are provided. The third component can be connected to the drive mechanism in various ways, including but not limited to threaded connections or snap-fit ​​connections. For example, the third component can be, for instance, an auxiliary handle.

[0083] During the machining operation of the workpiece by the first tool attachment 300, when the first tool attachment 300 reaches the target machining depth of the workpiece, the drive mechanism 1011 and the first tool attachment 300 stop moving axially in the housing 101. The target machining depth can be user-defined or preset by the power tool 1000; this embodiment does not impose specific limitations.

[0084] State 3, such as Figure 2 As shown in (c), the first tool attachment 300 finishes machining the workpiece. At this time, the drive mechanism 1011 and the first tool attachment 300 can move axially in the housing 101, allowing the drive mechanism 1011 to return to its initial position axially in the housing 101.

[0085] In this embodiment, the first component 200 is joined to the housing 101, allowing the first component 200 to be flexibly disassembled, thereby enabling the user to flexibly use the power tool 1000. The joining of the first component 200 to the housing 101 can be implemented in various ways, including but not limited to the following embodiments:

[0086] In Embodiment 1, a magnet is provided on the first surface of the housing 101, and correspondingly, the first component 200 is spliced ​​to the housing 101 via the magnet. The shape and position of the magnet on the first surface of the housing 101 are not limited in this embodiment. In Embodiment 2, a snap-fit ​​structure is provided on the first surface of the housing 101, and correspondingly, the first component 200 is spliced ​​to the housing 101 via the snap-fit ​​structure. The position of the snap-fit ​​structure on the first surface of the housing 101 is not limited in this embodiment.

[0087] The above-described embodiments 1 and 2 can be used in combination or individually.

[0088] For example, please see Figure 3 , Figure 3 A schematic diagram of the structure of a possible first component provided in an embodiment of this application is shown. For example... Figure 3 As shown in (a), a metal component 1013a and a snap-fit ​​structure 1013b are provided in the first surface 1013 of the housing 101; as Figure 3 As shown in (b), a third groove 203a and a snap-fit ​​structure 203b are provided in the first surface 203 of the first component 200; a magnet is provided in the third groove 203a, which can magnetically attract metal 1013a. The snap-fit ​​structure 1013b and the snap-fit ​​structure 203b are coupled, so that the first component 200 and the shell 101 are spliced ​​together.

[0089] In this embodiment, the first component 200 may include a support structure, which may include N points where the first component 200 contacts the workpiece surface. Thus, when the first component 200 contacts the workpiece surface, the stability of the first component 200 can be improved, thereby improving the perpendicularity of the first tool attachment 300 to the workpiece surface.

[0090] For example, please continue to see Figure 2 and Figure 3 The support structure in the first component 200 can be Figure 2 The three support legs 202 in the diagram, and the N points of the support structure are the points where the three support legs 202 contact the workpiece surface; or, please continue to refer to Figure 3 The support structure in the first component 200 can be as follows: Figure 3 The structure consisting of the reinforcing rib structure 204 and the side surface of the first component 200 shown in (b) is such that the N points of the support structure are the points where the reinforcing rib structure 204 contacts the workpiece surface.

[0091] Optionally, the first component 200 may also have a telescopic structure. This allows the length of the first component 200 to be adjustable, thereby adjusting the depth of workpiece machining by the first tool attachment 300. In the embodiments of this application, the telescopic structure of the first component 200 can be implemented in various ways, including but not limited to the following:

[0092] Method 1: The telescopic structure of the first component 200 is set in the support structure of the first component 200.

[0093] For example, please see Figure 4 The first component 200 has support structures 205A and 205B on both sides, and each support structure 205A and 205B is provided with a telescopic structure 2051; wherein, in Figure 4 In (a), the telescopic structure 2051 is in an unstretched state; Figure 4 In (b), the telescopic structure 2051 is in a telescopic state. Thus, by adjusting the telescopic length of the telescopic structure 2051, the lengths of the support structures 205A and 205B can be adjusted, thereby adjusting the length of the first component 200, and thus adjusting the machining depth of the first tool attachment 300 on the workpiece.

[0094] In method 2, the first component also includes a first structure, which is connected to the support structure to form a telescopic structure. Thus, the length of the first component can be adjusted by changing the connection between the first structure and the support structure, thereby adjusting the depth of workpiece machining by the first tool attachment 300.

[0095] For example, please continue to see Figure 5 The first component 200 includes a first structure 206 and a support structure 207. The first structure 206 and the support structure 207 are connected to form a telescopic structure of the first component 200. By adjusting the connection position of the first structure 206 and the support structure 207, the length of the first component 200 can be adjusted, thereby adjusting the depth of workpiece machining by the first tool attachment 300. Figure 5 As shown in (a), the first structure 206 and the support structure 207 are connected at a first position in the axial direction of the housing 101, at which time the length of the first component 200 is 1; as Figure 5 As shown in (b), the first structure 206 and the support structure 207 are connected at a second position in the axial direction of the housing 101, at which time the length of the first component 200 is length 2; when the first component is in contact with the surface of the workpiece, the distance between the first position and the surface of the workpiece is length 1, and the distance between the second position and the surface of the workpiece is length 2. When the first position is higher than the second position, length 1 is greater than length 2.

[0096] Optionally, the relative angle between the first structure 206 and the supporting structure 207 is adjustable. Thus, by adjusting the relative angle between the first structure 206 and the supporting structure 207, the angle between the first component 200 and the workpiece contact surface can be adjusted, allowing the user to process the workpiece at their desired angle, thereby meeting diverse processing needs. For an example, please continue to refer to... Figure 5 As shown in (c), by rotating the support structure 207, the relative angle between the first structure 206 and the support structure 207 can be adjusted, thereby adjusting the angle of the first component 200 relative to the contact surface of the workpiece, so that the user can use the power tool 1000 to drill holes at an angle on the workpiece.

[0097] Optionally, the side surface of the first component 200 can be made of a transparent or non-transparent material. The transparent material can be semi-transparent or fully transparent; this embodiment does not impose specific limitations. Thus, making the first component 200 transparent facilitates user observation of the operating conditions.

[0098] Optionally, an anti-slip pad can be provided on the contact surface between the first component 200 and the workpiece surface. This can reduce damage to the workpiece surface caused by the first component 200.

[0099] In one possible implementation, the side of the first component 200 can be any of a closed structure, an open-closed structure, or an open structure. Thus, setting the side of the first component 200 as a closed structure can prevent machining debris from splashing; alternatively, setting the side of the first component 200 as an open-closed structure allows for flexible control of the first component 200 to form an open or closed structure, facilitating the cleaning of machining debris from the first component 200; or, setting the side of the first component 200 as an open structure allows the user to easily observe the machining process. For an example, please refer to [link to example]. Figure 6 The side surface of the first component 200 may include, for example: Figure 6 The opening and closing structure 208a shown in (a) is shown in the figure; the side of the first component 200 may include, for example, the opening and closing structure 208a shown in the figure. Figure 6 The opening structure 208b shown in (b) of the diagram; the side surface of the first component 200 may include, for example, the opening structure 208b shown in (b). Figure 6 The opening and closing structure 208c is shown in (c) in the figure.

[0100] Optionally, the power tool 1000 may also include a controller that can control the opening / closing structure to form an opening or a closed opening when the side of the first component 200 is an opening / closing structure. This allows the first component 200 to be adapted to different machining conditions. For example, when the first tool attachment 300 is machining a workpiece, the controller can control... Figure 6The opening and closing structure 208c shown in (c) closes, forming a closed structure; after the first tool attachment 300 finishes processing the workpiece, the controller can control... Figure 6 The opening and closing structure 208c shown in (c) opens to form an open structure, which makes it easy for users to clean up processing debris.

[0101] Optionally, the main body of the power tool 1000 may further include a depth sensor, which is used to determine the machining depth of the workpiece by the first tool attachment 300. Thus, by incorporating a depth sensor into the main body of the power tool 1000, the power tool 1000 can measure the machining depth of the workpiece by the first tool attachment 300, thereby enabling the power tool 1000 to precisely control the machining depth of the workpiece by the first tool attachment 300, thus meeting the user's machining needs under different working conditions. For example, if the power tool 1000 can measure the machining depth of the workpiece by the first tool attachment 300, the power tool 1000 can also support drilling blind holes in the workpiece. The depth sensor may be one or more of an angle sensor, a vernier caliper, or a laser sensor, and this embodiment does not impose specific limitations.

[0102] In one possible implementation, when the first tool attachment 300 is replaced by the second tool attachment or when the workpiece's machining starting plane changes, the machining depth of the workpiece acquired by the depth sensor is initialized to a first value based on the first tool attachment 300. This allows for timely initialization of the depth sensor's measurements, effectively improving the sensor's measurement accuracy.

[0103] Optionally, the housing 101 may also be provided with a first control element and / or a second control element. The first control element can be used to adjust the working parameters of the power tool 1000, and the second control element can be used to adjust the functional mode of the power tool 1000. The working parameters may include, but are not limited to, at least one of the following: the output power of the power tool, the rotational speed of the first tool attachment 300, the predetermined depth of machining of the workpiece by the first tool attachment 300, the direction of machining of the workpiece by the first tool attachment 300, or the torque of the motor in the drive mechanism 1011. The functional modes may include, but are not limited to, at least one of a tapping machine mode, an electric screwdriver mode, or an electric drill mode. A tapping machine mode can be understood as the power tool 1000 having the function of a tapping machine, an electric screwdriver mode can be understood as the power tool 1000 having the function of an electric screwdriver, and an electric drill mode can be understood as the power tool 1000 having the function of an electric drill. The first or second control element may include, but is not limited to, one or more of a knob, a button, or a switch. Thus, a control element is provided for adjusting the working parameters of the power tool 1000, allowing users to flexibly adjust the working parameters of the power tool 1000 to meet the user's processing needs for the workpiece under different working conditions. And / or, the power tool 1000 has multiple function modes and provides a control element for switching function modes, allowing users to flexibly use the multiple functions of the power tool 1000.

[0104] Optionally, a second groove may also be provided on the housing 101 for placing a third tool accessory. The second groove may include one or more grooves, and the third tool accessory may be one or more commonly used tools. Thus, the surface of the housing 101 of the drive mechanism 101 is provided with a groove for placing commonly used tools, facilitating user access to the tools and effectively improving the user experience.

[0105] For ease of understanding, the power tool 1000 provided in the embodiments of this application will be described in detail below with reference to specific examples.

[0106] Please see Figure 7 , Figure 7 This is the third structural schematic diagram of the power tool 1000 provided in this application. Figure 7 In (a), the main body 100 of the power tool 1000 takes an L-shaped structure as an example. The depth sensor 400 includes an angle sensor 401, a gear 402, and a rack 403. The gear 402 meshes with the rack 403. The gear 402 is connected to the motor in the drive mechanism 1011 through the angle sensor 401, and the rack 403 is connected to the housing 101. One or more of the angle sensor 401, gear 402, and rack 403 can be disposed inside or outside the main body 100.

[0107] For example, in Figure 7 In (a), gear 402 and rack 403 are disposed within the main body mechanism 100, while angle sensor 401 can be disposed outside the main body mechanism 100. The angle sensor 401 can detect the relative position between the drive mechanism 1011 and the housing 101, and determine the machining depth of the first tool attachment 300 on the workpiece based on this relative position. Thus, the power tool 1000 can precisely control the machining depth of the first tool attachment 300 on the workpiece based on the machining depth obtained by the angle sensor 401, thereby meeting the user's machining needs under different working conditions. For example, if the power tool 1000 is a tapping machine and the first tool attachment 300 is a tap, the tapping machine can measure the machining depth of the tap on the workpiece, and it also supports drilling blind holes in the workpiece.

[0108] In one possible implementation, when the first tool attachment 300 begins processing the workpiece, if the depth value acquired by the depth sensor 400 does not change or the sound of the first tool attachment 300 processing the workpiece is abnormal, the user can apply a force (i.e., a third force) to a third component (e.g., an auxiliary handle 600) in the main body 100. This force acts on the drive mechanism, causing the drive mechanism 1011 to move axially in the housing 101. That is, the force applied by the user to the third component in the main body 100 can provide the first tool attachment 300 with the feed pressure for processing the workpiece.

[0109] Please continue reading Figure 7 In (a), the housing 101 includes a first groove 1012 and a second groove 1014; a magnet can be provided in the first groove 1012 to magnetically attract the first tool accessory 300; similarly, a magnet can also be provided in the second groove 1014 to magnetically attract the third tool accessory 500 (i.e., a tool accessory commonly used by the user).

[0110] Please continue reading Figure 7In (b) of the example, the second component of the power tool 1000, taking springs 1011A and 1011B as examples, includes a drive mechanism 1011 that further includes guide rails 1011C and 1011D. Spring 1011A is disposed in guide rail 1011C, and spring 1011B is disposed in guide rail 1011D. Spring 1011A is compressed in guide rail 1011C under the compression of housing 101, generating elastic force 1; spring 1011B is compressed in guide rail 1011D under the compression of housing 101, generating elastic force 2. The third component of the power tool 1000, taking an auxiliary handle 600 as an example, allows the user to apply force to the auxiliary handle 600. When the first tool attachment 300 processes the workpiece, the housing 100 and the first component 200 are stationary relative to the workpiece surface. The elastic force 1 generated by the spring 1011A and the elastic force 2 generated by the spring 1011B, and / or the force applied by the user to the auxiliary handle 600, act on the drive mechanism 1011, which can cause the drive mechanism 1011 and the first tool attachment 300 to move in the axial direction of the housing 100, so that the first tool attachment 300 processes the workpiece.

[0111] Please continue to participate. Figure 7 In (a), the first control element in the power tool 1000 is the first knob 700, and the second control element in the power tool 1000 is the second knob 800. By rotating the first knob 700, the user can adjust the working parameters of the power tool 1000. By rotating the second knob 800, the user can adjust the working mode of the power tool 1000.

[0112] In one possible implementation, when the auxiliary handle 600 is locked in a certain position, the axial movement of the drive mechanism 1011 within the housing 101 can be locked, thereby making the power tool 1000 suitable for the operational needs of a specific scenario. For example, as... Figure 8 As shown in (a), when the auxiliary handle 600 is in the open state, the drive mechanism 1011 and the first tool attachment 300 can move axially in the housing 101; as Figure 8 As shown in (b), when the auxiliary handle 600 is in the locked state, the movement of the drive mechanism 1011 in the axial direction of the housing 101 is locked, thereby enabling the power tool 1000 to drive screws normally when using the electric screwdriver function mode.

[0113] Optionally, in some possible embodiments of this application, the power tool 1000 may further include a human-machine interface component, which can be used to receive a first user instruction for adjusting the working parameters of the power tool 1000. The working parameters may include, but are not limited to, at least one of the following: the rotational speed of the first tool attachment 300, the depth of machining of the workpiece by the first tool attachment 300, the direction of machining of the workpiece by the first tool attachment 300, or the torque of the motor in the drive mechanism 1011. Thus, by providing a human-machine interface component in the power tool 1000, the working parameters of the power tool 1000 can be flexibly adjusted. The human-machine interface component may include, but is not limited to, one or more of a photoelectric module, a voice module, or a text interaction module. In one possible embodiment, the human-machine interface component may also be used to receive a second user instruction for adjusting the functional mode of the power tool 1000. The functional mode includes at least one of a tapping machine mode, an electric screwdriver mode, or an electric drill mode.

[0114] Please continue reading Figure 9 The power tool 1000 has a spring on its wire 1015. The spring's extension and retraction characteristics provide a buffer mechanism for the wire 1015, which can effectively prevent the wire 1015 from breaking when it is bent.

[0115] Optional, please continue to see Figure 9 The second side 1016 of the housing 101 can also be equipped with a display screen, which can display time information and / or working parameter information of the power tool 1000. In this way, the user can view the time information and / or working parameter information of the power tool 1000 through the display screen, so that the user can intuitively understand the processing status of the power tool 1000 and effectively improve the user experience.

[0116] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
