The motor 7 drives the transmission rod 8 to rotate, and the transmission rod 8 drives the main bevel gear 9 to rotate. The main bevel gear 9 drives the secondary bevel gear 10 to rotate, and the secondary bevel gear 10 drives the threaded rod 11 to rotate. The threaded rod 11 drives the slider 12 of the outer wall to move downward, and at the same time drives the movable plate 13 to move, and the plastic film is limited by the movable plate 13 and the fixed plate 15. After the adjustment is completed, the connecting plate 5 and the punching knife 6 are driven to move up and down by controlling the electric push rod 4 to extend and retract back and forth, so that the punching knife 6 punches the plastic film through the through hole 14.
