Figure 9 Structure diagram of the handle.

[0036] The insulating screwdriver comprises a handle 10, an execution assembly 20, a button 30 and a button retainer 40. The handle 10 is generally cylindrical, and the execution assembly 20 is inserted into one end of the handle 10. The button 30 is arranged on the side of the handle 10 and used to lock and unlock the execution assembly 20. The button retainer 40 is used to keep the button 30 on the handle 10 without falling off. The detailed structure of each part is described below.

[0037] The first end 10a of the handle 10 is provided with a first accommodating part 11 extending in the axial direction. The first accommodating part 11 is a blind hole, and its cross-sectional shape is generally rectangular. Its shape should be consistent with the shape of the part of the execution assembly 20 installed in the first accommodating part 11. After the execution assembly 20 is inserted into the first accommodating part 11, the two cannot rotate relative to each other, so that torque can be transmitted. At the mouth of the first accommodating part 11, a circular hole part with a larger diameter is arranged. The circular hole part is coaxial with the first accommodating part 11 and is used to install the button retainer 40. The diameter of the circular hole part is larger than that of the main body of the first accommodating part 11, so that a stepped hole is formed between the circular hole part and the first accommodating part 11. The bottom of the circular hole part is further provided with a third accommodating part 13. The third accommodating part 13 is an elongated blind hole parallel to the first accommodating part 11. The number of the third accommodating part 13 is 2. The third accommodating part 13 is radially away from the hole wall of the first accommodating part 11, and the two are separated by a solid part 14. The two third accommodating parts 13 are distributed at an interval of 180 degrees in the circumferential direction.

[0038] The side of the handle 10 is provided with a second accommodating part 12. The second accommodating part 12 is a square hole extending in the radial direction of the handle 10. The second accommodating part 12 is a blind hole. The diameter of the second accommodating part 12 is larger than that of the first accommodating part 11. The second accommodating part 12 communicates with the first accommodating part 11 and the third accommodating part 13.

[0039] The execution assembly 20 comprises an insulating sleeve 21 and a metal bit 23. The insulating sleeve 21 is in the shape of a quadrangular prism, and a blind hole is arranged in the center, and a groove 22 is arranged on the outer periphery. The metal bit 23 is a metal rod, and one end is a working head. The metal bit 23 is inserted into the blind hole of the insulating sleeve 21. The whole execution assembly 20 can be inserted into the first accommodating part 11 of the handle 10 through the insulating sleeve 21. The groove 22 of the insulating sleeve 21 is used to be inserted by the corresponding structure of the button 30 to limit the insulating sleeve 21 in the axial direction, so that the execution assembly 20 is kept in the first accommodating part 11 without falling out.

[0040] The button 30 comprises a force receiving part 31, two connecting parts 32, a clamping part 33, a convex 34, a cantilever 35 and a hook 36. The force receiving part 31 is an arc plate, one surface of which is used to receive the force of a user, and the other surface opposite to the surface is provided with two plate-shaped connecting parts 32, and the plate-shaped clamping part 33 is connected with the two connecting parts 32 and is spaced apart from the force receiving part 31. The force receiving part 31, the connecting parts 32 and the clamping part 33 enclose a square hole which is consistent with the shape of the force receiving part 31. When the button 30 is installed in the second accommodating part 12 of the handle 10 and the assembly 20 is installed in the first accommodating part 11 of the handle 10, the insulating sleeve 21 is inserted into the square hole of the button 30. The inner surface of the clamping part 33 is provided with the convex 34, which is embedded in the groove 22 of the insulating sleeve 21 when the insulating sleeve 21 is inserted into the square hole. The height (the size along the axial direction of the square hole) of the connecting part 32 is smaller than that of the force receiving part 31 and the clamping part 33, so that there is a space between the force receiving part 31 and the clamping part 33 on one side of the height direction of the connecting part 32, and the space is provided with the cantilever 35, one end of which is connected to the force receiving part 31 and the other end is suspended, and the end is provided with the hook 36. The hook 36 is a boss which protrudes outward in the radial direction.

[0041] When the button 30 is installed in the second accommodating part 12, the outer surface of the clamping part 33 is further provided with the spring 50 between the bottom of the first accommodating part 11, the spring 50 makes the button 30 have a tendency to be pushed out of the second accommodating part 12 in the radial direction, and the convex 34 of the inner surface of the clamping part 33 is kept embedded in the groove 22 of the insulating sleeve 21.

[0042] When the insulating sleeve 21 is pulled out of the first accommodating part 11, the button stopper 40 makes the button 30 still remain in the second accommodating part 12 without being pushed out of the second accommodating part 12 by the spring 50.

[0043] The button stopper 40 comprises a ring part 41 and two stop parts 42. The two stop parts 42 are distributed at an interval of 180 degrees in the circumferential direction. The stop part 42 is a cantilever structure provided on the end surface of the ring part 41, and the end of the cantilever is provided with a protrusion 43. The protrusion 43 protrudes towards the inside of the ring part 41.

[0044] The button limiting piece 40 is installed into the third accommodating part 13 of the handle 10. Specifically, the two limiting parts 42 are respectively inserted into the two third accommodating parts 13, and the ring part 41 is accommodated in the round hole part of the first accommodating part 11. Moreover, the limiting part 42 extends into the second accommodating part 12, thereby forming a limiting cooperation with the button 30. Specifically, the limiting part 42 and the protrusion 43 are inserted axially between the hook 36 and the force receiving part 31. In this way, when the button 30 has a tendency to move outward, the limiting part 42 and the protrusion 43 will block the hook 36, so that the button 30 cannot move outward. Moreover, the protrusion 43 of the button limiting piece 40 will also be blocked by the entity part 14 between the first accommodating part 11 and the third accommodating part 13, and the button limiting piece 40 cannot be axially detached from the third accommodating part 13, thereby forming a fixed connection.

[0045] During assembly, the spring 50 and the button 30 are first installed into the second accommodating part 12 of the handle 10, and then the button limiting piece 40 is inserted into the second accommodating part 12, thereby forming a limiting of the button 30, and the entity part 14 of the handle 10 forms a fixation of the button limiting piece 40. Thereafter, different types of execution assemblies 20 can be freely installed and detached. The above structure is simple and reliable, and is convenient for assembly.

[0046] The above merely provides a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present disclosure, and these modifications or replacements shall be encompassed within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
