The working principle is as follows:

abnormal use state: the device is provided with an electric shock prevention device 4, when a child pokes a jack on one side with an object, the object opens a first wedge block 301 first, then the object enters a groove of a mounting seat 403, at the moment, the mounting seat 403 drives a connecting rod 402 on one side to incline due to the force applied to one side, and further drives a swing rod 401 to incline, because the swing rod 401 is longer, one end of the swing rod 401 slightly inclines, and the other end of the swing rod 401 greatly deflects, so that the swing rod 401 drives a limit rod 4011 to move, when the mounting seat 403 drives the swing rod 401 through the connecting rod 402, because the swing rod 401 inclines, so that the limit rod 4011 of the swing rod 401 drives a movable plate 404 to move through a limit block 4041, the movable plate 404 drives an insulating baffle 406 to move through a fixed rod 405, because a connecting bracket of an insulating elastic sheet 501 is parallel to a first spring 202, an electric connection elastic sheet 5 cannot move, and when a connecting rod 4031 of the mounting seat 403 reaches an inclined support rod of the insulating elastic sheet 501, the insulating baffle 406 completely shields the contact conductive block 502, and the insulating baffle 406 of the jack at the other end also contacts the contact conductive block 502, so that the contact conductive block 502 is prevented from contacting a child handheld object, and the child is prevented from getting an electric shock;

locked and unlocked states during abnormal use: meanwhile, when the pressing rod 4031 of the mounting seat 403 reaches the inclined support rod of the insulating elastic sheet 501, the locking tongue 601 enters the locking hole of the movable plate 404, so that the mounting seat 403 cannot be pressed downwards continuously, when unlocking is needed, the protective shell 101 is opened, the T-shaped rod 605 is pressed, the T-shaped rod 605 drives one ends of the unlocking rods 603 at two ends, the unlocking rods 603 push the locking tongue 601 through the wedge-shaped block, so that the locking tongue 601 is separated from the locking hole of the movable plate 404, the movable plate 404 is reset under the action of the second spring 204, and the socket can be used normally;

and (3) normal use state: when using normal plug, the conducting strip of plug is with the mount pad 403 synchronous motion of both sides, thereby mount pad 403 passes through connecting rod 402 and drives pendulum rod 401 and remove, because the atress of pendulum rod 401 both sides is the same, thereby the unchangeable slip of pendulum rod 401 state keeps, thereby the gag lever post 4011 of pendulum rod 401 both sides can't drive the stopper 4041 removal of fly leaf 404, carry out the centre gripping to the plug conducting strip through first wedge 301, and the outer wall of first wedge 301 is provided with insulating rubber, thereby but centre gripping plug conducting strip, avoid the plug conducting strip to pop out under the effect of first spring 202.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
