| description | The invention discloses an elastic expansion ring. The elastic expansion ring comprises an elastic ring body of an annular column structure, wherein one end face of the elastic ring body forms a firstend face, the other end face of the elastic ring body forms a second end face, and the inner circumferential surface of the elastic ring body is provided an annular avoidance groove. The elastic expansion ring can effectively prevent a tube from breaking away from a spindle, and is low in cost and simple in structure. The elastic expansion ring is installed on the spindle of a winding machine, can effectively prevent the tube from breaking away from the spindle, and is low in cost and simple in structure. When the elastic expansion ring is under the action of pressure, the outer circumferential surface of the elastic expansion ring is expanded, and the expanded part of the elastic expansion ring is pressed against the inner wall of the tube, thereby achieving the function of fixing the tube, and when the pressure |
