The outer end of the eccentric column is also provided with an outer block edge with an outer diameter slightly less than the inner diameter of the outer tube, the eccentric column is covered with a section of c-shaped expansion sleeve, the section of the eccentric column is involute, the involute starting point and end point Angle distance is °, the starting point and end point is connected with a straight line segment.
