With the continuous improvement of the quality of life, every household is constantly introducing high-power electrical appliances. During the peak period of electricity consumption, the high-voltage power supply lines are subjected to high-intensity loads. Under the impact of continuous loads, high-voltage lines often appear The problem is that when electric maintenance personnel overhaul high-voltage lines, for personal safety, grounding clamps are often used for maintenance.

In the prior art, the currently used grounding pliers usually use a hook to hang the pliers head of the grounding pliers on the high-voltage wire. The connection makes the connection between this type of grounding clamp and the high-voltage electric wire unstable, and poor contact is prone to occur, which poses a great potential safety hazard to the life safety of maintenance personnel. At the same time, the grounding cable of the existing grounding clamp is usually exposed. During use, when the grounding clamp is connected with the high-voltage electric wire, it is easy to swing between the grounding cable and the pole of the grounding clamp. Swinging easily makes the grounding cable fall off from the grounding clamp, affecting the normal use of the grounding clamp, and further affecting the normal operation of electric power maintenance.
