Device for disassembling and assembling drainage wire

The invention relates to the technical field of high-voltage live working tools, in particular to a device for disassembling and assembling a drainage wire, which comprises an insulating shell, a clamping piece, a gear assembly, a driving piece and a connecting piece. A through hole is formed in the insulating shell, and a wire clamp to be connected penetrates through the through hole; at least part of the clamping piece can extend into the through hole and can move relative to the insulating shell so as to selectively clamp or loosen the wire clamp to be connected. The gear assembly is meshed with the clamping piece, and the gear assembly can drive the clamping piece to move; the driving piece can drive the gear assembly to move; the connecting piece is used for fixing a wiring terminal of the drainage wire. By arranging the gear assembly, driving the clamping piece, controlling the length of the clamping piece extending into the through hole, selectively clamping or loosening the broken part of the drainage
