The expansion screw is composed of a screw and an expansion tube, and the screw tail is conical. 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 conical portion is moved by the axial movement of the thread, and then the expansion tube is The outer peripheral surface forms a large positive pressure, and the angle of the cone is small, so that the wall, the expansion tube and the cone form a friction self-locking, thereby achieving a fixing effect. For example, the Sanfeng composite cable bracket is formed by friction self-locking between the wall, the expansion tube and the cone, thereby achieving a fixing effect.
