In this embodiment: when the plug is inserted downwards, the partial pressing plates 5 on the two sides of the metal sheet of the plug drive the first tooth socket plate 6 to move downwards, the spring 4 is elongated, the first tooth socket plate 6 drives the gear I7 to rotate, then the gear II 8 drives the second tooth socket plate 11 to move towards the baffle 15, so that the baffle 15 moves to the upper part of the plug, when the baffle 15 moves, the inclined plane part of the pressing block 16 slides along the upper end of the plug, when the plug is completely inserted tightly, the upper surface of the pressing plate 5 is flush with the upper surface of the socket 22, the baffle 15 moves to the farthest distance, the flat part of the bottom surface of the pressing block 16 slides to the upper end of the plug, so that the plug is clamped, and the end, far away from the second tooth socket plate 11, of the supporting shaft 12 is flush with the side surface of the supporting plate 13, so that whether the upper surface of the pressing plate 5 is flush with the upper surface of the socket 22 or not can be judged, so that whether the plug is completely inserted tightly can be judged, and an early warning and protection effect can be achieved, and when the plug is completely inserted tightly, the baffle 15 and the pressing block 16 can play a fixing role, the plug is prevented from breaking away from the socket 22 due to external force during subsequent use, the possibility of failure is reduced, the protection effect of the device on the plug connection part is further improved, and the technical problem that when the plug is inserted into a jack, if the plug is not completely inserted, a metal sheet on the plug is exposed to a part, a child can possibly use fingers to buckle the metal sheet to cause electric shock, and poor contact can be caused due to long-time looseness, so that short circuit failure occurs is solved.

Example two:

referring to fig. 4, based on the first embodiment, the present invention provides a technical solution: left surface fixedly connected with hinge 14 of two 11 of gullet boards, the right-hand member of the left end fixedly connected with baffle 15 of hinge 14, hinge 14's one end fixedly connected with briquetting 16 is kept away from to the lower surface of baffle 15, the one end that hinge 14 was kept away from to briquetting 16 is the inclined plane setting, baffle 15's first upper surface fixedly connected with fixed plate 17, the last fixed surface fixedly connected with fixed plate two 18 of two 11 of gullet boards, sliding connection has kelly 19 to run through side and the side about fixed plate two 18 about fixed plate one 17, kelly 19's right-hand member fixedly connected with side cap 20.

In this embodiment: when the plug needs to be pulled out, the side cover 20 is buckled, the clamping rod 19 is pulled towards one end of the supporting plate 13, the clamping rod 19 slides from the first fixing plate 17, then the baffle plate 15 is turned upwards, the plug is pulled out upwards, when the plug moves upwards, the spring 4 restores to pull the pressing plate 5 upwards, so that the second tooth groove plate 11 slides towards the right side, finally, the baffle plate 15 is turned to be in a horizontal state, the clamping rod 19 is inserted into the first fixing plate 17 again, and the device returns to an initial state and is simple and rapid to operate.

Example three:

referring to fig. 6, based on the second embodiment, the present invention provides a technical solution: spout 23 has all been seted up to the side inner wall about mounting groove 2, runs through and has seted up logical groove directly behind the trailing flank mounting groove 2 of protective housing 1, and the logical inslot wall of the 1 trailing flank of protective housing runs through sliding connection and has apron 24, and the inner wall of the equal sliding connection spout 23 in both ends about apron 24, the one end fixedly connected with protruding board 25 of protective housing 1 is kept away from to the upper surface of apron 24.

In this embodiment: when an electrical appliance plug needs to be inserted, the convex plate 25 is buckled firstly to pull the cover plate 24 towards the rear side, so that the opening of the mounting groove 2 is opened, the socket 22 is exposed, when the plug does not need to be inserted, the convex plate 25 is buckled to push the cover plate 24 to the upper side of the socket 22, and the socket 22 is shielded, so that the waterproof and dustproof effects are realized, and the use is convenient.

The working principle is as follows: when an electrical appliance plug needs to be inserted, the convex plate 25 is buckled firstly to pull the cover plate 24 towards the rear side, so that the opening of the mounting groove 2 is opened, the socket 22 is exposed, then the plug is inserted into the socket 22, when the plug is inserted downwards, the partial lower pressing plates 5 at two sides of the plug metal sheet drive the first tooth socket plate 6 to move downwards, the spring 4 is elongated, the first tooth socket plate 6 drives the first gear 7 to rotate, then the second gear 8 drives the second tooth socket plate 11 to move towards the baffle 15, so that the baffle 15 moves above the plug, when the baffle 15 moves, the inclined plane part of the pressing block 16 slides along the upper end of the plug, when the plug is completely inserted tightly, the upper surface of the pressing plate 5 is flush with the upper surface of the socket 22, the baffle 15 moves to the farthest distance, at the time, the flat bottom part of the pressing block 16 slides to the upper end of the plug, and at the time, one end of the support shaft 12, far away from the second tooth socket plate 11, is flush with the side surface of the support plate 13, whether be convenient for judge 5 upper surfaces of clamp plate flush with socket 22 upper surface, thereby be convenient for judge whether the plug is completely inserted tightly, play the early warning guard action, and baffle 15 and briquetting 16 can play the fixed action when the plug is completely inserted tightly, the plug is struggled with socket 22 because external force when avoiding follow-up use, reduce the possibility that the trouble takes place, further improve the guard action of device to plug connection department, solved when inserting the jack with the plug, if not inserting the plug completely, can make the sheetmetal on the plug expose partly, kid probably can buckle the sheetmetal with the finger and lead to electrocuteeing, and long-time not hard up can cause contact failure, thereby take place short-circuit fault's technical problem.

When the plug needs to be pulled out, the side cover 20 is buckled to pull the clamping rod 19 towards one end of the supporting plate 13, the clamping rod 19 is made to slip from the first fixing plate 17, then the baffle plate 15 is turned upwards, then the plug is pulled out upwards, when the plug moves upwards, the spring 4 restores to pull the pressing plate 5 upwards, so that the second tooth groove plate 11 slides towards the right side, finally, the baffle plate 15 is turned to the horizontal state, the clamping rod 19 is inserted into the first fixing plate 17 again, the device returns to the initial state, the operation is simple and fast, when the plug does not need to be inserted, the cover plate 24 is pushed to the position above the socket 22 by buckling the protruding plate 25, and the socket 22 is shielded, so that the waterproof and dustproof effects are achieved, and the use is convenient.
