When the user uses the plug 1 to insert the socket 2, the user should pay attention to make the slider 3 on the plug 1 slide with the slide groove 6 opened on the inner side of the cover 17, and insert the plug 1 into the socket 9 set on one side of the socket 2 through the sliding of the two, and a rotating disk 7 is set on one side of the socket 2, and three round holes are opened on the rotating disk 7, and the rotating disk 7 has a plurality of holes. The position and diameter of the circular hole are consistent with the socket 9 on the socket 2, and the circular hole on the rotating disk 7 slides with the limit member 8, and the other end of the limit member 8 is located on the inner side of the sliding hole 11 opened on the socket 2, and a return spring 12 is provided on the inner side of the sliding hole 11, and one end of the return spring 12 is fixedly connected to one end of the limit member 8. At this time, as the plug 1 moves, the pin 4 and the rectangular block 5 fixed on one side of the plug 1 will contact the rotating disk 7, and a circular hole is opened at the center of the rotating disk 7. The rotating disk 7 is fixed to one end of the rotating rod 14 through the circular hole opened in the center, and a rectangular groove 13 is opened at one end of the rotating rod 14. At this time, the pins on one side of the plug 1 4 and the rectangular block 5 will be inserted into the rotating disk 7 along the circular hole and rectangular groove 13 on the rotating disk 7. As the pins 4 are inserted, the limiting piece 8 on the inner side of the circular hole opened on the rotating disk 7 will be squeezed accordingly, and the limiting piece 8 will move to the sliding hole 11 and squeeze the reset spring 12, and release the limiting piece 8 from the rotating disk 7.
