technical field

The utility model relates to an electric tool, in particular to an improved universal grounding device.

Background technique

When the traditional grounding wire equipment is connected to the strain-resistant wire, there are generally such phenomena: the grounding wire head is not in good contact with the wire, and even in some cases, the grounding wire head (spring bayonet grounding) is seriously separated from the wire. In order to ensure The grounding wire head is in good contact with the wire to avoid the existence of the above hidden dangers. The operator must hang the grounding wire head and the wire vertically. After the grounding wire is hung, the insulating rod is also suspended on the wire. For the cross arm, the grounding wire can only be removed by pulling the copper wire part of the grounding wire, or when hanging the grounding wire, directly wrap the grounding wire around the insulating rod to prevent the insulating rod from falling. Therefore, the human body will inevitably touch the grounding wire during operation, causing potential safety hazards for operators in the process of hanging and removing the grounding wire.
