[0022] When it is necessary to cut the plastic, the plastic is placed on the table of the operating table 1, and the hydraulic cylinder 3 is started. The hydraulic cylinder 3 will drive the support plate 4 to move downward, the support plate 4 will drive the guide frame 5 to move downward, the guide frame 5 will drive the movable block 8 to move downward, the movable block 8 will drive the clamping block 9 to move downward, the clamping block 9 will drive the fixing seat 10 to move downward, and the fixing seat 10 will drive the cutting knife 11 to move downward, so that the cutting knife 11 contacts the plastic;

[0023] Secondly, the cutting knife 11 is put into operation, and the motor 6 is started at the same time, the motor 6 will drive the threaded rod 7 to rotate, and the rotation of the threaded rod 7 will drive the movable block 8 to move inside the guide frame 5, thereby driving the cutting knife 11 to move and cut the plastic;

[0024] Furthermore, the bottom of the support plate 4 is fixedly connected with a plurality of connecting columns 12, the bottom of the connecting columns 12 is fixedly connected with a fixing plate 13, one side of the fixing plate 13 is fixedly connected with an extension arm 14, and the bottom of the extension arm 14 is fixedly connected with a pressing cylinder 15;

[0025] When the hydraulic cylinder 3 drives the support plate 4 to move downward, the support plate 4 drives the connecting column 12 to move downward, the connecting column 12 drives the fixing plate 13 to move downward, the fixing plate 13 drives the extension arm 14 to move downward, the extension arm 14 drives the pressing cylinder 15 to move downward, and then the plastic is pressed by the multiple pressing cylinders 15 to prevent the plastic from being offset when the plastic is cut;

[0026] Further, the two ends of the threaded rod 7 are rotatably connected to the inside of the guide frame 5, and two slide grooves 17 are processed on both sides of the guide frame 5.
