[0017] Limiting protrusions 19 are provided at the middle positions of the left and right sides of the lifting plate 17. The limiting protrusions 19 are integrally formed with the lifting plate 17. The bottom of the limiting protrusions 19 is connected to the second electric cylinder 15, and the second electric cylinder 15 is installed on the second movable plate 14.
[0018] The base 1 is provided with a second slide rail 4 adapted to the slider on the bottom surface of the second movable plate 14 , and a rectangular notch is opened on the base 1 .
