[0029] The present invention realizes the holding or releasing of the conductor end by the grounding wire clamp 2 by setting a torsion spring 8 and a torsion spring traction mechanism 9, thereby increasing the practicality of the present invention. At the same time, the present invention increases the multi-angle adjustment of the grounding wire clamp 2 by setting a steering mechanism, which is convenient for maintenance personnel to use; the insulating wiring rod 1 is convenient for maintenance personnel to receive the present invention by setting a hydraulic system, a wire gathering hook 24 and a grounding rod snap buckle 25.
