In this way, when auxiliary plugging and unplugging are required, the arc-shaped plate 51 can be clamped on the thin-diameter shell 221. In this way, when the clamping frame 5 moves left and right along with the plug-and-play shell 4, the plug head 21 can be driven to perform plugging and unplugging operations.

[0035] In this embodiment, when power supply is required, the operator first inserts the head of the connection plug 2 into the shore power socket 1. After inserting the limiting strip 211 of the plug head 21 into the positioning groove 121, the control switch 122 can be pressed. Then, the locking frame 5 is lifted and clamped on the thin-diameter shell 221 through the arc-shaped plate 51. The electric cylinder 30 is started to drive the plug-in shell 4 and the locking frame 5 to move towards the side close to the shore power socket 1, thereby driving the connection plug 2 to be stably inserted into the shore power socket 1. When it is necessary to pull out, the electric cylinder 30 is started to drive the plug-in shell 4 and the locking frame 5 to move away from the shore power socket 1, thereby pulling out the connection plug 2 from the shore power socket 1. When the limiting strip 211 is separated from the control switch 122, the electric cylinder 30 can automatically stop. Then, the locking frame 5 is lowered, and thus it can be removed from the connection plug 2, so that the connection plug 2 can be quickly disassembled.

[0036] The above is a preferred embodiment of the present invention. Those skilled in the art of the present invention can also make changes and modifications to the above embodiment. Therefore, the present invention is not limited to the above specific embodiments.
