The lower end of the second support plate 10 is slidably connected to the upper end of the base 1. A second rotating shaft 11 is horizontally rotatably connected to the upper end of the second support plate 10. One end of the second rotating shaft 11 close to the middle of the base 1 is fixedly connected with a lifting plate 12. The lifting plate 12 is clamped at the end of the positioning column 5 away from the meshing disk 4.
