As the two sets of screws 20 rotate simultaneously, the lifting structure moves downward with the rotation of the screw 20. When the pressing roller 22 and the top roller 29 squeeze the cloth, the pressing frame 21 drives the slide plate 28 to move upward, the V-shaped groove squeezes the lever 27, and the lever 27 drives the slide plate 28 to squeeze the elastic member 25. At this time, the slide plate 28 exits the slot. As the screw 20 continues to rotate, the roller 23 rotates with the screw 20. The roller 23 and the housing 24 are connected by bearings and can rotate stably. At this time, the pressing frame 21 no longer feeds downward and stops at a specified position.
