The top of the head 22 has a first engaging portion 222 for fixing to the shaft 24 An object (not shown). In the embodiment, the first engaging portion 222 is exemplified by an inner hexagonal groove, and the shaft 24 has a thread for screwing on the object or indirectly connecting the object.

請一併配合圖3及圖4所示，該扣件30具有相連接的一第二卡合部32以及二臂34。該第二卡合部32與該第一卡合部222相匹配，用以以可拆離的方式結合在該第一卡合部222上，該二臂34相隔有一定距離，且該二臂34用以分別凸伸至該環部14的兩側並且於該二臂34上分別設置有一抵靠面342(圖6參照)。於本實施例中，所述的第二卡合部32與該二臂34為一體成形之結構，該第二卡合部32為與該內六角形凹槽相匹配的六角形柱；該二臂34的末端係向內彎折且互相靠近，並且於該二臂34上位於彎折處與末端之間分別形成有一凸起部341，該二凸起部341係朝接近該第二卡合部32的方向突出，且該二凸起部341分別具有一該抵靠面342，並且該二抵靠面342係相背對設置。 As shown in FIG. 3 and FIG. 4 together, the fastener 30 has a second engaging portion 32 and two arms 34 connected thereto. The second engaging portion 32 is matched with the first engaging portion 222 for being detachably coupled to the first engaging portion 222. The two arms 34 are separated by a certain distance, and the two arms are separated 34 is respectively protruded to the two sides of the ring portion 14 and an abutting surface 342 is respectively disposed on the two arms 34 (refer to FIG. 6). In the embodiment, the second engaging portion 32 and the two arms 34 are integrally formed, and the second engaging portion 32 is a hexagonal column matching the inner hexagonal groove; The ends of the arms 34 are bent inwardly and close to each other, and a convex portion 341 is formed between the bending portion and the distal end of the two arms 34, and the two convex portions 341 are adjacent to the second engaging portion.
