At this time, the connecting plug 1 can be pushed through the fixing block 12 to be inserted into the connecting socket 11, so that the connecting plug 1 and the connecting socket 11 are connected to each other. At this time, the limiting rod 111 is inserted into the first limiting hole 19 through the second limiting hole 110, which has a limiting effect between the fixing block 12 and the slider 13, thereby improving the stability of the connection between the connecting plug 1 and the connecting socket 11; the overall device is composed of the fixing block 12, the slider 13, the first mounting plate 14, the positioning rod 15, and the second mounting plate 1 6 cooperates with the positioning hole 18, so that the connecting plug 1 can be frequently inserted into or pulled out of the surface of the connecting socket 11, thereby improving the accuracy of mutual alignment when the connecting plug 1 is frequently inserted into or pulled out of the surface of the connecting socket 11, thereby reducing the need for the staff to carefully check and confirm whether the connecting plug 1 and the connecting socket 11 are aligned with each other each time when the connecting plug 1 needs to be frequently inserted into or pulled out of the surface of the connecting socket 11, which is cumbersome and easily leads to a decrease in the connection efficiency between the connecting plug 1 and the connecting socket 11, thereby reducing the labor of the staff.
