The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0039] See also Figure 1 and Figure 2The embodiment of the present application provides an electric tool 100, which includes a housing 10, a driving mechanism 20, a transmission mechanism 30, a functional part 40, a steering mechanism 50, a box 60, a controller 70, a gear adjustment mechanism 80, a display screen 90 and a power supply 110. The driving mechanism 20, the transmission mechanism 30, the steering mechanism 50, the box 60 and the controller 70 are all accommodated in the housing 10. The functional part 40 and the display screen 90 are both arranged in the housing 10. A part of the gear adjustment mechanism 80 is accommodated in the housing 10, and another part of the gear adjustment mechanism 80 is arranged in the housing 10. The driving mechanism 20, the transmission mechanism 30, the steering mechanism 50 and the functional part 40 are connected in sequence. When the driving mechanism 20 is in a working state, the driving mechanism 20 is used to drive the functional part 40 to move through the transmission mechanism 30. When the driving mechanism 20 is in a non-working state, the transmission mechanism 30 is used to constrain the movement of the functional part 40, so as to facilitate the disassembly of the functional part 40 and the replacement of the functional part 40. The functional part 40 is used to realize a specific function. For example, if the functional part 40 includes a rolling blade of an electric scissors, the rolling blade can realize the function of cutting an object when it moves. For example, if the functional part 40 includes a grinder of an electric grinder, the grinder can grind and polish an object when it moves. For example, if the functional part 40 includes a saw blade of an electric saw, the saw blade can realize the function of cutting an object when it moves. The steering mechanism 50 is used to adjust the relative position of the functional part 40 with respect to the driving mechanism 20, so as to expand the function of the functional part 40. The box 60 is used to facilitate the arrangement of the driving mechanism 20 and the transmission mechanism 30 on the housing 10. The controller 70 is the control center of the power tool 100. The gear adjustment mechanism 80 is electrically connected or signal-connected to the controller 70, and is used to adjust the force of the driving mechanism 20 on the functional component 40 through the controller 70. The display screen 90 is used to display the gear position of the gear adjustment mechanism 80. The power supply 110 is used to supply power.

[0040] Through the electric tool 100, the electric tool 100 can at least realize the following functions. First, the functional part 40 can be driven to move by the driving mechanism 20, the transmission mechanism 30, etc. to realize the specific function of the functional part 40; second, when the driving mechanism 20 is in a non-working state, the transmission mechanism 30 limits the movement of the functional part 40, thereby facilitating the disassembly of the functional part 40 and facilitating the replacement of the functional part 40; third, through the steering mechanism 50, the relative position of the functional part 40 with respect to the driving mechanism 20 can be adjusted, so that the function of the functional part 40 can be expanded, and the application scenario of the electric tool 100 provided in the embodiment of the present application can be expanded; fourth, through the controller 70 and the gear adjustment mechanism 80, the force of the driving mechanism 20 on the functional part 40 can be adjusted, that is, the functional part 40 can provide different gear working states, thereby expanding the application scenario of the electric tool 100.

[0041] It is worth noting that, in some embodiments, the electric tool 100 may not be provided with the above-mentioned steering mechanism 50, box 60, controller 70, gear adjustment mechanism 80 and display screen 90, and may also achieve the functions of the above-mentioned first and second aspects, that is, achieve the invention purpose of the embodiment of this application.

[0042] For the housing 10, see Figure 2 The housing 10 is used to provide protection for the driving mechanism 20, the transmission mechanism 30, the steering mechanism 50, the box 60 and the controller 70. The specific configuration of the housing 10 can be based on actual needs.

[0043] In some embodiments, the housing 10 includes a main body 101 and a handle 102, the handle 102 and the main body 101 are arranged at an angle, the main body 101 is used to accommodate the driving mechanism 20, the transmission mechanism 30, the steering mechanism 50, the box 60 and the controller 70, the functional part 40 is located at one end of the main body 101, and the gear adjustment mechanism 80 is located at the end of the main body 101 away from the functional part 40. The display screen 90 is provided at one end of the main body 101 close to the gear adjustment mechanism 80, and the power supply 110 is provided in the handle 102. The handle 102 is used for the user to hold the power tool 100.

[0044] It is worth noting that the specific form of the angle α between the main body 101 and the handle 102 can be reasonably set according to actual needs. The main body 101 and the handle 102 are not arranged on an extended line. On the one hand, it can facilitate the electrical connection between the controller 70, the drive mechanism 20, the gear adjustment mechanism 80, and the power supply 110 to avoid the entanglement of the wire harness inside the housing 10; on the other hand, when the user holds the handle 102, the gear adjustment mechanism 80 can be operated at the same time, and the display screen 90 provided on the main body 101 can also be intuitively and conveniently seen.

[0045] For the above-mentioned drive mechanism 20 and housing 60, please refer to Figure 2 The driving mechanism 20 is used to provide power for the functional part 40 to move. The box 60 is fixedly connected to the housing 10 to facilitate the driving mechanism 20 and the transmission mechanism 30 to be arranged on the housing 10. The specific implementation of the driving mechanism 20 can be set according to actual needs, as long as it can provide power to drive the functional part 40 to move. The specific structure of the box 60 can be reasonably set according to actual needs, as long as it can facilitate the driving mechanism 20 and the transmission mechanism 30 to be arranged on the housing 10.

[0046] In some embodiments, the driving mechanism 20 includes a power source 201 and a gear box 202, the gear box 202 is accommodated in the housing 60, the power source 201 is arranged outside the housing 60, the output end of the power source 201 passes through the housing 60 and is connected to the gear box 202, the gear box 202 is arranged in the housing 10, and the output end of the gear box 202 is connected to the transmission mechanism 30. Through the gear box 202, the power of the power source 201 is transmitted to the transmission mechanism 30, thereby providing power for the movement of the functional part 40.

[0047] It is worth noting that, in some embodiments, the power source 201 includes any one of a DC motor, an AC motor, a stepper motor and a servo motor.

[0048] In some embodiments, the gearbox 202 includes an inner gear ring 2021, a sun gear 2022, planetary gears 2023 and a planet carrier 2024, wherein the inner gear ring 2021 is fixed to the housing 60; the output end of the power source 201 passes through the housing 60 and is connected to the sun gear 2022, and the power source 201 is used to drive the sun gear 2022 to rotate; the planetary gears 2023 are respectively meshed with the sun gear 2022 and the inner gear ring 2021; the planetary gears 2023 are connected to the planet carrier 2024, and the planet carrier 2024 is connected to the transmission mechanism 30. Through the gearbox 202, since the planetary gears 2023, the sun gear 2022 and the inner gear ring 2021 are meshed, the friction loss is small during power transmission, the efficiency of power transmission is high and it helps to reduce noise. The gearbox 202 is a prior art and will not be described in detail here.

[0049] It is understandable that the drive mechanism 20 is not limited to the above implementation, and may also have other forms. For example, in some embodiments, the drive mechanism 20 only includes a motor (not shown). The motor is connected to the transmission mechanism 30, and the motor drives the functional part 40 to move through the transmission mechanism 30.

[0050] For the transmission mechanism 30 and the functional part 40, please refer to Figure 2 and Figure 3 The transmission mechanism 30 is connected to the functional component 40, and the transmission mechanism 30 is used to transmit the power provided by the driving mechanism 20 to the functional component 40. The functional component 40 is used to provide a specific function of the electric tool 100.

[0051] In some embodiments, the transmission mechanism 30 includes a toggle member 301, a limit member 302 and a rotating shaft 303. The toggle member 301 is connected to the driving mechanism 20. When the driving mechanism 20 includes the gear box 202, the toggle member 301 is specifically connected to the planetary carrier 2024 of the gear box 202, and the rotating shaft 303 is connected to the functional member 40. The driving mechanism 20 can drive the toggle member 301 to drive the rotating shaft 303 to rotate. The limit member 302 is used to abut against the rotating shaft 303 to constrain the rotating shaft 303 to drive the toggle member 301 to rotate when the driving mechanism 20 is in a non-working state.

[0052] Optionally, the toggle member 301 is integrally arranged with the planet carrier 2024, or the toggle member 301 is fixedly connected or detachably connected with the planet carrier 2024. When the planet carrier 2024 rotates, the toggle member 301 rotates synchronously with the planet carrier 2024. The toggle member 301 is used to transmit the power provided by the driving mechanism 20 to the rotating shaft 303. When the rotating shaft 303 rotates, the rotating shaft 303 directly or indirectly drives the functional member 40, thereby realizing a specific function. For example, if the functional member 40 includes a rolling blade of an electric scissors, then when the rotating shaft 303 rotates, the rolling blade rotates, thereby realizing the function of cutting an object. For example, if the functional member 40 includes a grinding tool of an electric grinder, when the rotating shaft 303 rotates, the grinding tool rotates, thereby realizing grinding and polishing of the object. For example, if the functional member 40 includes a saw blade of an electric saw, when the rotating shaft 303 rotates, the saw blade rotates, thereby realizing the function of cutting an object.

[0053] The limiting member 302 is used to constrain the rotating shaft 303 , so that when the electric tool 100 is in a non-working state or the driving mechanism 20 is in a non-working state, the rotating shaft 303 can be constrained from rotating, thereby limiting the rotating shaft 303 from driving the toggle member 301 to rotate.

[0054] Through the above-mentioned transmission mechanism 30, on the one hand, when the driving mechanism 20 of the electric tool 100 provided in the embodiment of the present application is in a working state, or when the electric tool 100 is in a working state, the driving mechanism 20 can drive the toggle member 301 to rotate, and the toggle member 301 drives the rotating shaft 303 to rotate, so that the rotating shaft 303 drives the functional part 40 to realize specific functions such as trimming, cutting, grinding, and polishing. On the other hand, when the user touches the functional part 40, for example, when replacing the functional part 40, the user applies a disassembly force to the functional part 40. Since the limit member 302 restricts the rotating shaft 303, the rotation of the rotating shaft 303 is restricted, and the rotation of the toggle member 301 is restricted, so that the disassembly force applied to the functional part 40 can act on the functional part 40, thereby making it easy to disassemble the functional part 40 and providing a good user experience.

[0055] It is worth noting that the transmission mechanism 30 is not limited to the above implementation. In some embodiments, please refer to Figure 4The toggle member 301 is provided with at least two fork legs 3011, and the fork legs 3011 are sleeved on the rotating shaft 303. The transmission mechanism 30 also includes a positioning sleeve 304, and the positioning sleeve 304 is provided on the shell 10. The positioning sleeve 304 is stationary relative to the shell 10. The positioning sleeve 304 is sleeved on the fork legs 3011, and the limiting member 302 is provided between the two fork legs 3011; the limiting member 302 contacts the inner side surface of the positioning sleeve 304, and the limiting member 302 contacts the outer side surface of the rotating shaft 303.

[0056] Through the transmission mechanism 30, when the driving mechanism 20 is working, the toggle member 301 connected to the driving mechanism 20 rotates, and the fork leg 3011 of the toggle member 301 rotates along with the toggle member 301, and the fork leg 3011 pushes the limiting member 302 to rotate, and the limiting member 302 pushes the rotating shaft 303, and the fork leg 3011 pushes the rotating shaft 303, so that the rotating shaft 303 rotates under the action of the fork leg 3011 and the limiting member 302, that is, the driving mechanism 20 drives the rotating shaft 303 to rotate, and then the rotating shaft 303 drives the functional member 40 to realize a specific function.

[0057] In addition, when the driving mechanism 20 is in a non-working state, if a force, such as a disassembly force, is applied to the functional part 40, the force transmitted to the rotating shaft 303 through the functional part 40 acts on the limit member 302, and the limit member 302 is stuck on the outer side surface of the rotating shaft 303 and the inner side surface of the positioning sleeve 304, thereby limiting the rotation of the fork leg 3011 and limiting the rotation of the toggle member 301, so that the disassembly force applied to the functional part 40 can act on the functional part 40, thereby making it easy to disassemble the functional part 40 and providing a good user experience.

[0058] It is worth noting that, in some embodiments, the limiting member 302 includes a cylindrical pin and a ball.

[0059] It is worth noting that, in some embodiments, the number of the fork legs 3011 is three, the three fork legs 3011 are arranged around the rotating shaft 303, the three fork legs 3011 are distributed outside the rotating shaft 303, the number of the limiting members 302 is three, and a limiting member 302 is arranged between two adjacent fork legs 3011.

[0060] It is understandable that the number of the fork legs 3011 is not limited to three, and may also be in other forms.

[0061] It is understandable that the number of the limiting members 302 disposed between two adjacent fork legs 3011 is not limited to one, and may be other numbers.

[0062] It is worth noting that, in some embodiments, see Figure 3 The outer side of the rotating shaft 303 has a first part 3031 and a second part 3032, and the distance L1 between the first part 3031 and the axis of the rotating shaft 303 is greater than the distance L2 between the second part 3032 and the axis of the rotating shaft 303; the first part 3031 is used to apply a force toward the inner side of the positioning sleeve 304 to the limiting member 302, so that the limiting member 302 abuts against the rotating shaft 303, thereby constraining the rotating shaft 303 to drive the toggle member 301 to rotate. Through this arrangement, it is convenient for the first part 3031 to apply a force to the limiting member 302, and it is convenient to limit the limiting member 302 to the outer side of the rotating shaft 303 and the inner side of the positioning sleeve 304, so as to facilitate the restriction of the rotation of the fork leg 3011 and the toggle member 301, so that the disassembly force applied to the functional member 40 can act on the functional member 40, so that the functional member 40 is easy to disassemble and the user experience is good.

[0063] It is worth noting that the first part 3031 and the second part 3032 can be arranged in a variety of forms. In some embodiments, the first part 3031 is an arc surface, and the second part 3032 is a plane. In other embodiments, the first part 3031 is a plane, and the second part 3032 is a plane. In some other embodiments, the first part 3031 is a convex part protruding away from the axis of the rotating shaft 303, and the second part 3032 is a concave part facing the axis of the rotating shaft 303. In some other embodiments, the number of the first part 3031 is multiple, the number of the second part 3032 is multiple, the number of the first part 3031 and the number of the second part 3032 are the same, and the first part 3031 and the second part 3032 are cross-distributed on the outer side of the rotating shaft 303.

[0064] For the above-mentioned steering mechanism 50, please refer to Figure 5 The steering mechanism 50 is accommodated in the housing 10 , and the steering mechanism 50 is connected to the transmission mechanism 30 and the functional part 40 respectively. The steering mechanism 50 is used to adjust the position of the functional part 40 relative to the driving mechanism 20 and the transmission mechanism 30 , thereby expanding the function of the electric tool 100 .

[0065] In some embodiments, see Figure 5The steering mechanism 50 has an output shaft 501, and the output shaft 501 is connected to the functional part 40. Specifically, the output shaft 501 passes through the housing 10 and is connected to the functional part 40. In some embodiments, the output shaft 501 is connected to the functional part 40 through a fastener 120. The input end of the steering mechanism 50 is connected to the rotating shaft 303, and there is a preset angle θ between the rotating shaft 303 and the output shaft 501, and the preset angle θ is greater than zero. Through the steering mechanism 50, the direction of action of the rotating shaft 303 is changed, and the position of the functional part 40 relative to the rotating shaft 303 can be flexibly set to expand the function of the functional part 40.

[0066] In some embodiments, the preset angle θ is 90 degrees.

[0067] In some embodiments, one implementation of the steering mechanism 50 is that, in addition to the output shaft 501, the steering mechanism 50 further includes a first bevel gear 502 and a second bevel gear 503, the first bevel gear 502 and the second bevel gear 503 are meshed, the rotating shaft 303 is connected to the first bevel gear 502, and the output shaft 501 is connected to the second bevel gear 503. Through the steering mechanism 50, when the driving mechanism 20 drives the rotating shaft 303 to rotate, the rotating shaft 303 drives the first bevel gear 502 to rotate, the first bevel gear 502 drives the second bevel gear 503 to rotate, and the second bevel gear 503 drives the output shaft 501 to rotate, so that the output shaft 501 drives the functional part 40 to rotate, thereby realizing the specific function of the functional part 40.

[0068] It is worth noting that the steering mechanism 50 is not limited to the above-mentioned implementation method, but may also have other forms. For example, the steering mechanism 50 includes a gear (not shown) and a rack (not shown), the gear is meshed with the rack, the rotating shaft 303 is connected to the gear, and the rack is connected to the output shaft 501. In this way, the direction of action of the rotating shaft 303 can also be changed to expand the function of the functional part 40.

[0069] For the controller 70 mentioned above, see Figure 2 The controller 70 is the control center of the electric tool 100 provided in the embodiment of the present application. The controller 70 is electrically connected to the power supply 110, the drive mechanism 20, the gear adjustment mechanism 80 and the display screen 90 respectively. The controller 70 is used to adjust the state of the drive mechanism 20 according to the state of the gear adjustment mechanism 80, for example, to adjust the output power of the drive mechanism 20. The controller 70 is used to adjust the gear of the gear adjustment mechanism 80 displayed on the display screen 90 according to the state of the gear adjustment mechanism 80.

[0070] It is worth noting that the program steps involved in the controller 70 adopt existing program steps, and the controller 70 also adopts existing processors, such as Intel's I 3 processor, AMD Ryzen processor, etc.

[0071] For the above-mentioned gear adjustment mechanism 80 and display screen 90, please refer to Figure 5 and Figure 6 , a part of the gear adjustment mechanism 80 is accommodated in the housing 10. When the housing 10 includes the main body 101, a part of the gear adjustment mechanism 80 is accommodated in the main body 101, and another part of the gear adjustment mechanism 80 is arranged at an end of the main body 101 away from the functional part 40. The display screen 90 is arranged at an end of the main body 101 away from the functional part 40; the gear adjustment mechanism 80 is connected to the controller 70, and the gear adjustment mechanism 80 is used to adjust the force of the driving mechanism 20 on the functional part 40 through the controller 70, and the display screen 90 is used to display the gear of the gear adjustment mechanism 80, thereby expanding the use scenario of the power tool 100.

[0072] In some embodiments, the gear adjustment mechanism 80 includes a first adjustment member 801 and a detection member 802, wherein the first adjustment member 801 is connected to the housing 10, and the detection member 802 is electrically connected to the controller 70. The first adjustment member 801 and the detection member 802 are accommodated in the housing 10. The first adjustment member 801 is used to adjust the state of the detection member 802, and the controller 70 is used to obtain the state of the detection member 802, and adjust the state of the driving mechanism 20 according to the state of the detection member 802, for example, adjust the output power of the driving mechanism 20.

[0073] It is worth noting that, in some embodiments, the first adjustment member 801 includes a gear, the detection member 802 includes a rotary potentiometer, the first adjustment frame is rotatably connected to the detection member 802, and when the first adjustment member 801 rotates, the detection member 802 rotates, so that the resistance value of the detection member 802 changes, the voltage value of the detection member 802 changes, and the controller 70 detects the voltage value of the detection member 802. The controller 70 controls the speed of the power source 201 of the drive mechanism 20 according to the voltage value of the detection member 802, thereby adjusting the output power of the drive mechanism 20. The controller 70 also controls the display state of the display screen 90 according to the voltage value of the detection member 802, so as to facilitate viewing the state of the gear adjustment mechanism 80 and improve the user experience.

[0074] It can be understood that the first adjusting member 801 is not limited to the above-mentioned gear, and the detecting member 802 is not limited to the above-mentioned rotary potentiometer, and can also have other forms. For example, the first adjusting member 801 includes a slider (not shown in the figure), and the detecting member 802 includes a position sensor (not shown in the figure). The slider can move relative to the position sensor, and the first adjusting member 801 slides. The position sensor detects the position change of the first adjusting frame, and the controller 70 detects the state of the position sensor. The controller 70 controls the rotation speed of the power source 201 of the driving mechanism 20, thereby realizing the adjustment of the output power of the driving mechanism 20.

[0075] It is worth noting that, in some embodiments, the gear adjustment mechanism 80 includes, in addition to the implementation forms of the first adjustment member 801 and the detection member 802, a second adjustment member 803, the second adjustment member 803 is rotatably connected to the housing 10, and the inner wall of the second adjustment member 803 is provided with a toothed structure 8031 ​​for engaging with the first adjustment member 801, the first adjustment member 801 is coaxially arranged with the detection member 802, and the first adjustment member 801 is rotatably connected with the detection member 802. When the user rotates the second adjustment member 803, the second adjustment member 803 drives the first adjustment member 801 to rotate, and the first adjustment member 801 drives the state of the detection member 802 to change, so that the controller 70 detects the state of the detection member 802, and can control the output of the driving mechanism 20.

[0076] It is worth noting that, in some embodiments, the second adjusting member 803 is a ring-shaped member covering an end of the main body 101 of the housing 10 away from the functional member 40 .

[0077] It is understandable that the second adjusting member 803 is not limited to the above implementation manner, and may also have other forms. For example, the second adjusting member 803 includes a knob.

[0078] It is worth noting that, in some embodiments, the gear adjustment mechanism 80, in addition to the implementation forms of the above-mentioned first adjusting member 801, the detecting member 802 and the second adjusting member 803, also includes a mounting seat 804 and a positioning member 805. The mounting seat 804 is arranged in the shell 10, the second adjusting member 803 is rotatably connected to the mounting seat 804, and the positioning member 805 is elastically connected to the mounting seat 804; the inner wall of the second adjusting member 803 is provided with a plurality of slots 8032, and when the second adjusting member 803 rotates relative to the shell 10, the positioning member 805 is used to engage with the plurality of slots 8032. When the second adjusting member 803 is rotated, the position of the second adjusting member 803 relative to the mounting seat 804 changes, and the positioning member 805 moves from one slot 8032 to another slot 8032, thereby fixing the gear adjusted by the gear adjustment mechanism 80. At the same time, when the second adjusting member 803 is rotated, the first adjusting member 801 engaged with the toothed structure 8031 ​​on the inner wall of the second adjusting member 803 rotates, and the first adjusting member 801 drives the state of the detection member 802 to change, so that the controller 70 detects the state of the detection member 802, thereby controlling the output of the driving mechanism 20.

[0079] It is worth noting that, in some embodiments, a surface of the positioning member 805 facing the second adjusting member 803 has an arc surface, so as to facilitate the movement of the positioning member 805 between different slots 8032. In some other embodiments, the positioning member 805 includes a ball, so as to facilitate the movement of the positioning member 805 between different slots 8032.

[0080] In order to facilitate readers to understand the technical solution of the present application, one working mode of the electric tool 100 is now described. Please refer to Figures 3 to 6 When the power source 201 is working, the power source 201 drives the sun gear 2022 to rotate, the sun gear 2022 drives the planetary gear 2023 to rotate, the planetary gear 2023 drives the planetary carrier 2024 to drive the toggle member 301 to rotate, the fork foot 3011 of the toggle member 301 moves with it, the fork foot 3011 pushes the limit member 302 to rotate, the limit member 302 pushes the rotating shaft 303, the fork foot 3011 pushes the rotating shaft 303, so that the rotating shaft 303 rotates under the action of the fork foot 3011 and the limit member 302, the rotating shaft 303 drives the first bevel gear 502 to rotate, the first bevel gear 502 drives the second bevel gear 503 to rotate, the second bevel gear 503 drives the output shaft 501 to rotate, so that the output shaft 501 drives the functional part 40 to rotate, so as to realize the specific function of the functional part 40.

[0081] When the functional part 40 needs to be disassembled, the driving mechanism 20 is placed in a non-working state, and the fastener 120 is rotated. The force transmitted to the rotating shaft 303 through the fastener 120 and the functional part 40 acts on the limit member 302. The limit member 302 is stuck on the outer side surface of the rotating shaft 303 and the inner side surface of the positioning sleeve 304, thereby limiting the rotation of the fork leg 3011 and limiting the rotation of the toggle member 301. The force applied to the fastener 120 can remove the fastener 120 from the functional part 40, thereby facilitating the disassembly of the functional part 40 and providing a good user experience.

[0082] When the movement speed of the functional part 40 needs to be adjusted, the second adjusting part 803 in the gear adjustment mechanism 80 can be rotated, then the first adjusting part 801 rotates, the detection part 802 rotates, the state of the detection part 802 changes, the controller 70 detects the state of the detection part 802, the controller 70 controls the power source 201 to adjust the rotation speed, the rotation speed of the rotating shaft 303 changes, and the movement speed of the functional part 40 changes.

[0083] In the embodiment of the present application, the electric tool 100 includes a housing 10, a driving mechanism 20, a transmission mechanism 30 and a functional part 40, wherein the driving mechanism 20 and the transmission mechanism 30 are both accommodated in the housing 10; the driving mechanism 20, the transmission mechanism 30 and the functional part 40 are connected in sequence; the transmission mechanism 30 includes a toggle member 301, a limit member 302 and a rotating shaft 303, the toggle member 301 is connected to the driving mechanism 20, and the rotating shaft 303 is connected to the functional part 40; the driving mechanism 20 is used to drive the toggle member 301 to drive the rotating shaft 303 to rotate; the limit member 302 is used to abut the rotating shaft 303, so as to constrain the rotating shaft 303 to drive the toggle member 301 to rotate when the driving mechanism 20 is in a non-working state. With the electric tool 100 provided in the embodiment of the present application, on the one hand, the driving mechanism 20 can drive the toggle member 301 to drive the rotating shaft 303 to rotate, so that the rotating shaft 303 drives the functional part 40 to realize specific functions such as trimming, cutting, grinding, and polishing. On the other hand, when the user touches the functional part 40, for example, when replacing the functional part 40, the user applies a disassembly force to the functional part 40. Since the limit member 302 restricts the rotating shaft 303, the rotation of the rotating shaft 303 is restricted, and the rotation of the toggle member 301 is restricted. Therefore, the disassembly force applied to the functional part 40 can act on the functional part 40, thereby facilitating the disassembly of the functional part 40 and providing a good user experience.

[0084] The present application also provides an embodiment of an electric scissors 200, see Figure 7 and Figure 8 The electric scissors 200 include the electric tool 100. The functional part 40 of the electric tool 100 includes a rolling blade 21, and the functional part 40 is connected to the rotating shaft 303, so that the rotating shaft 303 can drive the rolling blade 21 to rotate to achieve cutting of the object. The specific structure and function of the electric tool 100 can refer to the above embodiment, and will not be repeated here.

[0085] It is worth noting that, in some embodiments, the electric scissors 200 further include a static blade 22, which is connected to the housing 10 and is used to form a shearing action with the rolling blade 21. The rolling blade 21 and the static blade 22 facilitate cutting of items.
