The positioning fastener member includes a mainbody, at least three clip members and an external screw structure. The at least three clip members are flexibly connected to the mainbody, and each of the clip members is an arc plate and has an end portion. The external screw structure is disposed on an outer surface of the mainbody. The outer cover is detachably connected to the positioning fastener member. The outer cover includes an inner space and an inner screw structure, and the inner screw structure matches the external screw structure. When the inner screw structure of the outer cover and the external screw structure of the positioning fastener member are screwed together, the positioning fastener member is accommodated in the inner space.
