[0032] In actual use, first, the vehicle wheel is placed into the cavity in the middle of the frame body 1, then the tire of the vehicle wheel is clamped by the two oppositely arranged first clamping assemblies 2, so that there is a gap between the tire and the hub. Then the tire is clamped by the second clamping assembly 3, so as to expand the gap between the tire and the hub. The first clamping assembly 2 no longer abuts against the tire.
