[0009] Optionally, the fixing part is fixed with a fixing sheet on the end away from the bundling part.

[0010] By adopting the technical scheme, when the pushing assembly is pulled away from the end abutting against the bundling assembly, the end of the pushing assembly close to the bundling assembly moves towards the movable cavity, and then the pushing assembly extrudes the bundling part to move towards the insertion cavity. When the pushing assembly is pulled to be perpendicular to the bundling assembly, the bundling groove and the wire hole are connected in the axial direction, the pushing assembly is continuously supported, the wire is inserted along the axial direction of the wire hole, the support on the pushing assembly is gradually released, the extrusion of the pushing assembly on the bundling part is reduced, the elastic potential energy stored in the bundling part is released when the pushing assembly is released, the bundling part drives the wire to abut against the fixing part and is firmly clamped in the bundling groove, the stability of the connection is ensured, the electrical failure and safety hazard caused by poor contact are reduced, and in the process of wiring of the wire, the disassembly and assembly of the wire by the bundling part can be completed synchronously by pulling or releasing the pushing assembly, the operation of disassembly and assembly of the wire is very convenient, other tools are not needed for operation, and the working efficiency of wiring is improved.

[0013] Optionally, the end of the connecting piece, on which the rotating shaft is installed, is fixed with an abutting block, and the side, away from the connecting piece, of the abutting block is a plane.

[0014] By adopting the technical scheme, in the installed state, the abutting block can more uniformly and effectively transmit the force applied by the pushing part to the bundling part, compared with direct contact, the abutting block and the bundling part can provide a larger contact area, thereby increasing the stability of the bundling part on the abutting block, and the bundling part is not easy to slip off the abutting block.

[0015] Optionally, one end of the pressing block towards the movable cavity is a transition smooth.

[0016] By adopting the above technical scheme, the transition smooth shape can make the contact between the pressing block and the elastic wire binding part more uniform and smooth. When the pushing assembly exerts extrusion force on the wire binding part, the transition smooth design can reduce the friction force of the pressing block sliding on the surface of the wire binding part, making the sliding between the pressing block and the wire binding part easier and reducing the damage to the surface of the wire binding part.

[0018] By adopting the above technical scheme, when no wiring operation is performed, the connecting piece is firmly fixed at the bottom of the shell, which can prevent the user from inadvertently pulling the pushing piece; when the wire is clamped by the wire binding part, the pushing piece may move in the opposite direction due to the reaction force of the wire binding part. The clamping of the limiting protrusion and the limiting block can effectively prevent the displacement of the connecting piece, thereby ensuring that the wire can be stably clamped in the wire binding groove and reducing unnecessary troubles and potential safety risks caused by misoperation.

[0019] Optionally, a gap is reserved between the fixed block and the end of the connecting piece.

[0020] By adopting the above technical scheme, the reserved gap provides enough space for the operator to hold the pushing piece, so that the force can be applied more conveniently when inserting or pulling out the wire, and the operator can pull the pushing piece more easily, which can generate greater force with smaller force, thereby more easily overcoming the resistance of the elastic wire binding part to complete the clamping operation of the wire.

[0021] Optionally, it further comprises a leakage protection socket, the leakage protection socket comprises a base and an upper cover, a wiring mechanism is installed in the base, and the base and the upper cover are connected in a clamped manner.

[0022] By adopting the above technical scheme, the wiring mechanism can quickly and firmly fix the wire. By installing the wiring mechanism in the leakage protection socket, the wire can be disassembled and assembled more conveniently when the leakage protection socket performs leakage protection, thereby improving the work efficiency.

[0023] Optionally, it further comprises a leakage protection switch, the leakage protection switch comprises a base and an upper cover, a wiring mechanism is installed in the base, and the base and the upper cover are connected in a clamped manner.

[0024] By adopting the technical scheme, the wiring mechanism can quickly and firmly fix the wires, and the wiring mechanism installed in the residual current protective switch can effectively protect the wires from loosening or falling off.

[0025] In summary, the present application has at least the following advantages:

[0026] 1. Only need to pull the pusher in the circumferential direction of the rotating shaft and insert the wire, and then release the pusher, the wiring operation can be quickly completed, without complex tools and cumbersome steps, greatly improving the wiring efficiency, saving time and labor cost.

[0027] 2. The elastic potential energy stored in the wire bundling part is released when the pusher is released, so that the wire is firmly clamped in the wire bundling groove, ensuring the stability of the connection, and reducing the electrical failure and safety hazard caused by poor contact.
