When the clamping frame 61 moves downward, the inner cavity of the groove and the bottom of the U-shaped connecting plate 611 moves to the top of the extrusion push plate 81, which will drive the push plate 81 to move downward, and the clamping frame 61 below will continue to move downward. When the push plate 81 moves downward, it will squeeze the spring 813, and at the same time, it will drive the rack plate B82 to move downward. When the rack plate B82 moves downward, it will drive the rotating gear 83 to rotate. When the rotating gear 83 rotates, it will drive the screw rod 85 to rotate through the belt C84. When the screw rod 85 rotates, it will drive the threaded sleeve C86 to move forward. When the threaded sleeve C86 moves forward, it will drive the cutting knife 87 to move forward through the moving rod. When the cutting knife 87 moves forward, it will cut the yarn.The staff can observe whether the yarn is broken before cutting and record it, which is beneficial to the staff's subsequent data statistics. After the test is completed, the clamping frame 61 below can be driven to move upward to recover, which is beneficial to the sequential testing of the strength of the entire roll of yarn on the yarn roller 49, and reduces the work intensity of the staff and improves the efficiency of the test.
