The grounding device is configured to position electric power lines of different specifications by placing a sliding tube over the outside of the power line, and then rotating the lifting screw counterclockwise to drive the limit support plate to move into the inside of the sliding tube, thereby pressing the power line tightly against the conductive metal part. When inspecting and maintaining power lines of different specifications, the power line will not be temporarily separated from the conductive metal parts due to shaking, thereby avoiding safety hazards caused by loose grounding during power inspection of the power line.
