In the normal use state, the convex part of the movable pressing plate is located in the long slot, and does not interfere with the telescoping of the sub-board and the mother board.

[0058] More specifically, the pull rope displacement switch 10 is a rotating member, which can be understood as a rotating disc, the rotating disc is rotationally connected to the outer side wall of the mother board 1, one end of the mother board pull rope 7 is fixedly connected to the outer edge of the bottom side of the rotating disc, the rotation of the rotating disc promotes the displacement of the mother board pull rope 7, and the displacement of the mother board pull rope 7 simultaneously promotes the movement of the telescopic end of the elastic telescopic plate assembly and the movable pressing plate on the mother board 1. In this case, the rotating disc simultaneously drives the telescopic end of the elastic telescopic plate assembly and the movable pressing plate on the mother board. In order to facilitate driving, a knob is arranged on the outer side of the rotating disc, thereby facilitating the rotation of the rotating disc.

[0059] Of course, in order to better use, a spring pin can be arranged on the side wall of the mother board to control the reset of the rotating disc. The edge of the rotating disc is provided with a ratchet, when the rotating disc rotates, the ratchet passes the spring pin, thereby preventing the rotating disc from rotating back.
