[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Two symmetrically distributed limiting disks 12 are fixedly sleeved on the outer side of the screw rod 10. Each limiting disk 12 is rotatably connected to the vertical part of the installation frame 7. Through the setting of the limiting disks 12, rotational limitation can be carried out on the screw rod 10. The horizontal part of the feeding plate 13 is slidably connected to the support table 4.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , A positioning mechanism 15 is jointly arranged on the installation frame 7 and the first gear 9. The positioning mechanism 15 includes positioning holes 151. A positioning hole 151 is opened at the left end of the first gear 9. There are multiple positioning holes 151, and the multiple positioning holes 151 are arranged in a circular array on the first gear 9.
