Since the shaft hole 11 and the first collar 1 are both eccentrically disposed, the peripheral wall thickness of the shaft hole 11 and the peripheral wall thickness of the first collar 1 are both non-uniform, and thus, in the process of rotating the first collar 1 or the second collar 2, the position of the shaft hole 11 is changed due to the non-uniform wall thickness, thereby changing the position of the axis of the shaft hole 11. In addition, because the peripheral wall thickness of the shaft hole 11 and the peripheral wall thickness of the first lantern ring 1 are uneven, the range of the total wall thickness around the shaft hole 11 is greatly increased, and the position adjusting range of the axis of the shaft hole 11 is further increased.
