[0041] When the plug 1 is pulled out, the pulling rod 12 is pulled outwards, and the pulling rod 12 slides under the action of the pulling force, and the other end of the pulling rod 12 drives the hanging table 11 to swing and be disconnected from the clamping hook 211, and the pulling rod 12 is continuously pulled outwards, and the pulling rod 12 and the plug 1 are completely pulled out from the plug slot 21 of the socket 2, so that the plug 1 is pulled out, and the plug 1 is not needed to be held and pulled outwards while the switch is pressed, and the plug 1 is conveniently and labor-savingly pulled out, the plug 1 is not needed to be held, the peripheral space of the plug 1 is saved, and the plug 1 can be easily pulled out in a small space.

[0042] One end of the pulling rod 12 is fixedly provided with a pull ring 121 for fingers to pull outwards, so that the plug 1 is pulled outwards, the operation is more convenient, the force is better applied, and the operation space is more saved.

[0043] The other end of the pulling rod 12 is provided with a linkage inclined surface 122 inclined along the swinging direction of the hanging table 11, a pushing arm 111 is fixedly arranged on the hanging table 11, and the pushing arm 111 can slide along the linkage inclined surface 122 and drive the hanging table 11 to swing. The other end of the pulling rod 12 is in contact with the pushing arm 111 on the hanging table 11 through the linkage inclined surface 122, when the pulling rod 12 is pulled outwards, the pushing arm 111 is lifted by the linkage inclined surface 122, so that the hanging table 11 is reversely rotated around the rotating shaft, the hanging table 11 and the clamping hook 211 are disconnected, and when the pulling rod 12 is pushed towards the inside of the plug 1, the pushing arm 111 is lowered along the linkage inclined surface 122, so that the hanging table 11 is forwardly rotated around the rotating shaft, and the hanging table 11 and the clamping hook 211 are connected.

[0044] The pushing arm 111 on the hanging table 11 is a hook-shaped structure formed by bending, and the hook-shaped structure is provided with a slope structure matched with the linkage inclined surface 122.
