[0037] The working principle and use process of the utility model are as follows: when in use, the cloth is first laid flat on the top of the base 1 so that the part to be cut is directly below the cutting knife 5, and then the cylinder 3 is started so that the piston end of the cylinder 3 pushes the pressing plate 4 and the cutting knife 5 to move downward, and at the same time, the pressing plate 4 descends to drive the connecting rod 13, the fixing plate 14 and the rubber plate 15 to move downward, so that before the cutting knife 5 contacts the cloth, the fixing plate 14 and the rubber plate 15 can press and position the cloth, and when the cutting knife 5 contacts the cloth and continues to descend to cut it, the connecting rod 13 drives the second limiting ring 17 to move upward, and at this time the spring 18 contracts, so that the rubber plate 15 can always press and position the cloth, and the waste generated by cutting is The waste and cloth scraps can fall into the collecting tank 92 through the holes on the surface of the through-hole 7 and the porous plate 8. At the same time, the density of holes on the surface of the porous plate 8 is relatively high, which can prevent the cloth laid on the top from falling. When it is necessary to clean the waste and cloth scraps, first start the servo motor 103 so that the output end of the servo motor 103 drives the transmission rod 105 to rotate. The rotation of the transmission rod 105 can drive the screw rod 104 to rotate. The rotation of the screw rod 104 can drive the connecting plate 102 and the scraper 101 to move forward, so that the waste and cloth scraps inside the collecting tank 92 can be pushed from the inside of the collecting tank 92 to the inside of the waste hopper 19. At this time, the user can conveniently clean the waste and cloth scraps in the waste hopper 19.
