Abstract

The application discloses a high ground wire setting device which is used for the technical field of electric auxiliary tools and comprises a device body, wherein the device body is a conductor and is connected with one end of a ground wire, the device body is provided with a clamping groove, the side wall of the clamping groove is provided with a traction part used for traction of the device body and enabling the clamping groove to encircle the periphery of a lead, the side wall of the clamping groove is provided with a locking mechanism used for limiting the lead to the clamping groove, and the device body is also provided with an unlocking mechanism connected with the locking mechanism and used for unlocking. During the use, the operator bypasses the traction part above the wire through the insulating rod and the like, and pulls the traction part again, so that the device body continuously rises until the wire enters the clamping groove. The device body conducts the lead with the ground wire to realize the grounding of the lead. The locking mechanism locks the wire in the clamping groove, so that the device body is prevented from being separated from the wire. The overhead ground wire setting device can be directly locked with the lead, so that the difficulty in connecting the ground wire with the lead is reduced, and the lead is conveniently grounded by an operator.
