Eccentric wheels 9 are symmetrically provided at the left and right ends of the rotating shaft 8, and connecting cylinders 10 are sleeved on the two eccentric wheels 9, and the eccentric wheels 9 and the connecting cylinders 10 are rotatably connected. Adjusting rods 11 are fixedly provided on the bottom surfaces of the two connecting cylinders 10, and hinge seats 12 are fixedly provided at the ends of the bottom surfaces of the two adjusting rods 11. A lifting seat 13 which can slide up and down is provided in the U-shaped frame 7, and the two hinge seats 12 are connected to the corresponding parts of the top surface of the lifting seat 13. A cutting knife 14 is fixedly provided on the bottom surface of the lifting seat 13, and the end of the rotating shaft 8 extending out of the U-shaped frame 7 is connected to the output shaft of the motor 17.
