As a further preference, the grounding device includes a box body, a grounding plate and a control board parallel to each other are inserted on one side of the box body, and a through hole is provided at the outer end of the grounding plate for being sleeved on the grounding bolt; The control board is inserted into the box body and connected with the inner end of the grounding plate; the control board is inserted into the box body and can slide horizontally along the box body. A pressure spring is arranged therebetween, and a power source is connected between the signal transmitter and the ground plate in the box, and the power source, the signal transmitter, the control plate and the ground plate form the lock control circuit.

As a further preference, a semi-circular arc-shaped groove is provided at the outer end of the control board, which is used for clamping on the grounding bolt to improve the electrical conductivity.

As a further preference, the signal transmitter and the single-chip microcomputer are connected by wireless signals.

The beneficial effects of the present invention are as follows: since the conductor clip is provided with a servo motor on the side of the hook access port, the servo motor is provided with a single-chip microcomputer for controlling the operation of the servo motor; After the control circuit is turned on through the grounding bolt, it can send a signal to the single-chip microcomputer, so that the servo motor drives the locking lever to rotate to realize the unlocking. Therefore, the locking control circuit in the grounding device can control whether the hooking port on the conductor clip is opened or not. The structure is simple and can be Mutual locking can avoid misoperation events caused by wrong order when assembling and disassembling the ground wire, and ensure the safety of operation.
