The expansion screw is composed of screw and expansion tube. The tail of the screw is conical: the inner diameter of the cone is larger than that of the expansion tube. When the nut is tightened, the screw moves outward. Axial movement through threads. By moving the cone part, a large positive pressure is formed around the expansion tube, and the angle of the cone is very small, so that the wall, the expansion tube and the cone can form friction self-locking, thus achieving a fixed effect.
