The invention discloses a fixing element, which comprises a conical connecting piece, at least comprising a conical connecting piece head part and a threaded part; the expansion sleeve is arranged on the conical connecting piece in a sleeving mode, and a diffuser ring is integrally connected to the expansion sleeve; the expansion sleeve is provided with a groove in the axial direction so that the expansion sleeve can be of a cylindrical structure with the side face open, a first edge and a second edge are formed at the groove, the first edge is provided with a limiting protrusion, and the second edge is provided with a limiting groove. The limiting protrusion is matched with the limiting groove so that the limiting protrusion can be limited in the limiting groove. The middle of the expansion sleeve protrudes outwards in the radial direction of the expansion sleeve to form a sleeve protruding part. The expansion sleeve and the diffuser ring which are integrated are adopted, materials are saved, and cost is reduced.
本发明公开了一种固定元件，包括：锥形连接件，所述锥形连接件至少包括呈锥形的连接件头部和螺纹部；膨胀套筒，所述膨胀套筒套设于所述锥形连接件上，所述膨胀套筒上一体式地连接有扩压环；其中，所述膨胀套筒沿其轴向开设有剖口以使所述膨胀套筒呈侧面开放的筒状结构，所述剖口处形成第一边缘和第二边缘，所述第一边缘设有限位凸起，所述第二边缘设有限位槽，所述限位凸起与所述限位槽相匹配以使所述限位凸起被限位于所述限位槽的内部；其中，所述膨胀套筒的中部沿其径向方向向外鼓凸以形成套筒凸起部。本发明采用一体式的膨胀套筒和扩压环，节省了材料，降低了成本。
