[0025] A sliding cavity 11 arranged in the side plate 10, a sliding plate 13 slidingly arranged in the sliding cavity 11, a first sliding rod 14 and a second sliding rod 15 slidingly arranged on the sliding plate 13, and a handle 20 arranged at the distal end of the first sliding rod 14 and the second sliding rod 15;

[0026] A clamping mechanism arranged between the first sliding rod 14 and the second sliding rod 15 and used for clamping the grounding wire.

[0027] In use, a plurality of grounding wires are inserted into the corresponding connecting holes 3 of the connecting plate 2, and the connecting mechanism is used to connect the plurality of grounding wires. When the plurality of grounding wires need to be disassembled, the connecting mechanism is first disconnected from the plurality of grounding wires, and then the handle 20 is pulled to move the first sliding rod 14 and the second sliding rod 15 in opposite directions, so that the clamping mechanism can insulate and clamp the grounding wire. Then, the handle 20 is pressed downward to pull out the grounding wire from the connecting hole 3, thereby avoiding the safety problem of directly contacting the grounding wire when disassembling the grounding wire.
