When the first guide rod 3 and the second guide rod 10 rotate, they can move in the grooves of the first transmission rod 2 and the second transmission rod 9. The servo motor 28 drives the first guide rod 3 and the second guide rod 10. When rotating, the first transmission rod 2 also drives the upper guide rod 7 and the lower guide rod to move, and the upper guide rod 7 and the lower guide rod can reciprocate in the groove of the first transmission rod 2. While moving, the upper guide rod 7 and the lower guide rod also drive the upper slider 6 and the lower slider 22 to reciprocate, and the upper slider 6 and the lower slider 22 slide inside the upper slide rail 5 and the lower rail 23 when moving. When the upper slider 6 and the lower slider 22 move, they drive the second transmission rod 9 and the lower cutter 21 to move.
