The insulating rod can be threadedly connected with the first arm body and the second arm body as an insulating handle for the operator to operate by hand. When not in use, the insulating rod can be disassembled and placed to reduce the occupied space.

Further, the ground wire is a copper wire.

Further, there are anti-skid patterns on the insulating handle to enhance the operator's grip and avoid slipping.

Further, the card slot is provided with anti-skid lines, which enhances the contact friction between the card slot and the wire, and makes the clamping more stable.

Further, the first arm body is provided with a connecting bolt, and the connecting lug of the grounding wire is fixedly connected to the first arm body through the connecting bolt, so as to facilitate the assembly and disassembly of the grounding wire.

The beneficial effects of the present invention are:

The scissors-type grounding clamp of the present invention only needs to hold the insulating handles of the first arm body and the second arm body with both hands and make them close together, so that the first clamping opening and the second clamping opening can be opened, and according to the rectangular shape of the bus bar The structure or wire can be connected through the first clamp or the second clamp. It is no longer time-consuming and laborious to twist the rod. The scissors pull can greatly improve the installation efficiency. At the same time, the clamp of the present invention is suitable for It is suitable for various types of conductors such as wires and busbars, with firm installation and high reliability.
