[0033] When in use, a polypropylene sheet is placed on the operating table 1, and the cutting position of the polypropylene sheet is adjusted to be placed directly below the cutting knife 10. The clamping block 22 is driven to move downward by rotating the second threaded rod 21, so that the polypropylene sheet can be fixed by the clamping block 22 to ensure the stability of the polypropylene sheet during cutting; the cutting knife 10 is driven to rotate by starting the cutting device 9, and the cutting knife 10 is driven to move downward by the driving member 5. When the cutting knife 10 contacts the sheet, the sheet can be cut. When the cutting knife 10 needs to move forward and backward, the servo motor 19 is started, and the servo motor 19 drives the first threaded rod 18 to rotate. When the first threaded rod 18 rotates, it can drive the slider 4 to slide in the slide groove 3, thereby driving the cutting knife 10 to move forward and backward, so as to complete the cutting operation of the polypropylene sheet.
