In the existing public literature, CN213232338U-a fast trimming machine for leather processing is publicly provided with a base, and the top two sides of the base are connected with support plates, and the top of the support plate is connected with a crossbeam. A groove is provided in the middle of the top of the base, wherein a worm gear is provided inside the groove, and a worm is meshed on the right side of the worm gear. There are various types of existing trimming machines for leather processing. Although they can be used for leather trimming, they still have the following disadvantages:

[0003] 1. In the existing trimming machines for leather processing, the waste scraps generated by trimming are generally scattered on the ground, which is not conducive to cleaning. In order to solve this problem, a collection box is generally placed next to the trimming machine to collect the waste scraps.
