[0021] Specifically, one side of the inner wall of the shell 3 is rotatably connected to a second shaft 7, the second shaft 7 extends to the interior of the box body 1, and a second transmission assembly is arranged on the outside of the second shaft 7. The second transmission assembly includes a rack 10 fixedly connected to one side of the two sliders 16, and one end of the second shaft 7 is fixedly connected to a gear 9, which is meshingly connected to the two racks 10. By setting the second transmission assembly, the two connecting plates 13 can move toward each other.

[0022] Specifically, a sliding component is provided on one side of the inner wall of the box body 1, and the sliding component includes two symmetrically distributed slide grooves 11 opened on one side of the inner wall of the box body 1, and the insides of the two slide grooves 11 are slidably connected with sliders 16. Through the set sliding component, the rack 10 can be made more stable during the movement process, and a wiring component is provided inside the box body 1.
