The expansion screw consists of a screw and an expansion tube. The tail of the screw is a cone, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the cone part moves through the axial movement of the thread, and then forms a great positive pressure on the outer surface of the expansion tube, and the Angle of the cone is very small, so that the friction between the wall, the expansion tube and the cone is self-locking, and then achieves the fixing effect.
