[0032] Next, specifically describe its overall specific settings and functions.

[0033] As Figures 1-5 shown, a fixed rod 18 is slidably connected to the inner wall of the slider 17. The fixed rod 18 is fixedly connected to the surface of the chute on the mounting plate 1. A second spring 19 is sleeved on the surface of the fixed rod 18. The two ends of the second spring 19 are respectively fixedly connected with the slider 17 and the mounting plate 1.
