When the lock hole 5 rotates, the separation and combination indicator rod 13 is driven to rotate, thereby driving the fixed ring 17 and the first gear 14 outside it to rotate. When the fixed ring 17 rotates, the movable conductive sheet 18 rotates and can contact with the corresponding fixed conductive sheet 11 to realize the opening and closing operation.

[0023] An insulating baffle 12 is detachably installed on the outside of the first wiring slot 10 and the second wiring slot, and a circular groove is provided on the surface of the insulating baffle 12.
