Background
In order to ensure safety, the grounding wire needs to be hung after power failure of power equipment, the current dismounting mode is manually completed, generally, a wire end clamp (a double-spring type hook, a throat type hook and the like) is hung on a conductive part and clamped tightly through an insulating operating rod, or a silicon rubber handle at the bottom of the insulating operating rod is held by wearing insulating gloves and rotated to enable the wire end clamp (a flat spiral hook) to tightly press the conductive part. Either method requires manual lifting of the insulating operating rod to erect it.
