[0027] Working principle: First, the stretch film to be cut is conveyed under the cutter 8 through the conveyor belt 6, and the corresponding adjustment plate 3 is adjusted according to the height of the package to be cut. When the height of the package to be cut is higher, the shorter adjustment plate 3 can be pushed into the shell 1. When the height of the package to be cut is lower, the higher adjustment plate 3 can be pushed into the shell 1, so that the adjustment plate 3 is located below the stop plate, and the active bevel gear 16 is driven by the motor 4 to rotate, and the active bevel gear 16 drives the driven bevel gear 15 to rotate, and the driven bevel gear 15 drives the screw 13 to rotate, and the screw 13 rotates to move the moving plate 9 rotates, and the movable plate 9 moves with the cutter 8. When the top side of the movable plate 9 contacts the adjusting plate 3 pushed into the shell 1, the movable plate 9 will move upward with the adjusting plate 3, so that the top side of the adjusting plate 3 abuts against the abutting plate, so that the rotating rod 11 rotates. The rotating rod 11 rotates to engage the clamping plate with the clamping wheel 14, so that the screw 13 cannot rotate, so as to limit the position of the cutter 8. When the cutter 8 is not working, the protective plate 7 can be inserted into the base shell 2 from the front side of the base shell 2, and the blade of the cutter 8 falls into the knife groove on the top side of the protective plate 7, so as to protect the blade of the cutter 8.
