The movable plug block 4 has one end of the spring 20 fixedly connected to the inside of the movable plug block 4, and the other end of the spring 20 is fixedly connected to the connecting block 22. When the box cover 2 needs to be opened, the movable plug block 4 is pressed to make the front of the clamping block 19 slide along the inclined surface of the bottom end of the movable plug block 4, thereby pushing the clamping block 19 to rotate with the connecting rod 3 23 as the center of the circle. When the clamping block 19 rotates to a certain angle, the bottom end of the movable plug block 4 fits with the inner wall of the limit block 21, and at this time, the box cover 2 is pulled to make the box cover 2 and the main box The body 1 rotates with the hinge block 1 3 as the hinge, and at the same time, the box cover 2 drives the internal connecting block 2 22 to move outward, and the connecting block 22 drives the connecting rod 4 26 to move outward. At this time, the top of the clamping block 19 slides on the inclined surface of the movable plug block 4 and rotates with the connecting rod 3 23 as the center of the circle, thereby pushing the spring 18 to shrink toward the rear end. When the bottom end of the connecting rod 4 26 is higher than the top of the clamping block 19, it is affected by the elastic potential energy of the spring 18 and pushes the clamping block 19 back to its position to prepare for the next switch.
