Each lead screw 9 is matched with the corresponding transmission mechanism. A driving mechanism is arranged on the back of the gantry 1. Each transmission mechanism is matched with the driving mechanism. By using the arranged adjusting plates 2, rolling balls 3 and lead screws 9, a plurality of rolling balls 3 can be smoothly pressed against both sides of the upper cutter 7 and the lower cutter 8. Thus, not only can the gap between the upper cutter 7 and the lower cutter 8 be quickly adjusted, but also both sides of the upper cutter 7 and the lower cutter 8 can be adjusted simultaneously, ensuring that the upper cutter 7 can be quickly adjusted directly above the lower cutter 8. This not only reduces a certain labor intensity, but also improves the adjustment effect and efficiency.
