The upper rod body is located outside the lower rod body. An outer inclined wedge surface 12 and an inner inclined wedge surface 13 are formed at the connection between the upper rod body and the lower rod body. The outer inclined wedge surface 12 is located above the outer side, and the inner inclined wedge surface 13 is located below the inner side.
