When the quick grounding moving contact 700 needs to be contacted with the quick grounding fixed contact 600, the second rotating shaft 810 is driven by the third driving piece to slide in the sliding guide hole 110 so as to separate the second gear 811 from the second rack, and at this time, the quick grounding moving contact 700 falls under the action of self gravity until contacting with the quick grounding fixed contact 600 directly below.
