It can be seen from the figure that no matter how the screw core swings, it will not fall off from the screw sleeve. This is because part of the bead 5 is stuck in the hole 6 of the screw sleeve 1 and the other part is stuck in the screw core 2. In the groove 8, it plays the role of positioning. If the screw sleeve rotates clockwise, the beads 5 can only slide in the groove 8 of the screw core 2 under the driving of the screw sleeve 1 and cannot drive the screw core 2 to rotate. If the screw sleeve 8 rotates in the opposite direction, the bead 5 will be stuck on the stop 7 of the screw core 2 so as to drive the screw core 2 to rotate.
