Both sides of the mounting plate 9 are provided with a fixing groove 11 that slides with the fixing plate 8. The fixing plate 8 is provided with an inclined chamfer 12 on the side close to the mounting plate 9.

[0024] It should be noted that, by tilting the chamfer 12 , when the mounting plate 9 moves downward, the two fixing plates 8 are pressed away from each other, and the spring 14 is also pressed.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The cross section of the splicing cavity 7 is rectangular, and the inner wall of the splicing cavity 7 is symmetrically slidably connected with a movable plate 13 with a rectangular cross section.
