[0024] In this embodiment, preferably, four slots 15 are formed on the surface of the bottom cover 1. The inner walls of the four slots 15 are respectively slidably connected to the surfaces of the four insertion blocks 3. Right-angle brackets 16 are fixedly provided at the top and bottom of the bottom cover 1. Mounting holes are formed on the surfaces of the four right-angle brackets 16. Four limiting slots 17 are formed inside the bottom cover 1. The fronts of the four blocks 13 are all arranged as inclined surfaces. The four insertion blocks 3 slide into the interiors of the four slots 15 to complete the positioning of the top cover 2, facilitating the alignment of the top cover 2 and the bottom cover 1 and improving the installation efficiency.
[0025] In this embodiment, preferably, the inner walls of the four limiting slots 17 are respectively slidably connected to the surfaces of the four blocks 13. The interiors of the four limiting slots 17 are respectively communicated with the interiors of the four slots 15. The four limiting slots 17 respectively sleeve the exteriors of the four return springs 14, and the four return springs 14 respectively sleeve the exteriors of the four sliding rods 12. The limiting slots 17 resist the blocks 13 after the blocks 13 move downward by a certain distance, preventing the return springs 14 from being excessively compressed.
[0026] In this embodiment, preferably, two of the four pull ropes 11 are respectively wound around the two convex parts of one of the cam 8s, and the other two pull ropes 11 are respectively wound around the two convex parts of the other cam 8. The surfaces of the four pull ropes 11 are respectively slidably connected to the inner walls of the four U-shaped plates 10. When one cam 8 rotates, it pulls the two pull ropes 11 through the two convex parts. The U-shaped plate 10 holds the middle parts of the pulled pull ropes 11 through its inner wall, facilitating the further winding of the pulled pull ropes 11 around the surface of the cam 8, thereby pulling the sliding rods 12.
