Abstract
A fixing assembly includes a connecting sleeve, a spike member, and an elastic member; the spike member is rotatably connected to the connecting sleeve; one end of the elastic member is connected to the connecting sleeve, and the other end of the elastic member is connected to the spike member; the elastic member at least helically surrounds and abuts against the outer peripheral wall of the spike member, and the elastic member is configured to generate elastic deformation when the spike member rotates relative to the connecting sleeve along a direction opposite to the helical surrounding direction of the elastic member; there is an included angle between the direction of elastic deformation and the axial extension direction of the spike member to form a helical convex elastic structure.
