Abstract
The present disclosure discloses an electric shock-proof plug that comprises an insulating sleeve, a plug body, and a reset member. The plug body is movably disposed in the insulating sleeve. An inner wall of the insulating sleeve comprises a guiding groove, and an outer wall of the plug body comprises a sliding member movably coupled to the guiding groove. The sliding member moves in the guiding groove to drive the plug body to move between a high position and a low position. When the plug body moves to the low position, a connector of the plug body is exposed out of the insulating sleeve, and the reset member generates an elastic resetting force. When the plug body moves to the high position, the connector is retracted back into the insulating sleeve. A user will be prevented from getting an electric shock when unplugging the electric shock-proof plug.
