After measuring the minimum distance between the two sides of the tire, the distance between the two laser ranging sensors 20 is reduced by the minimum distance, and the tire diameter can be roughly calculated (since the tire pattern can have a reasonable error, which is filled by the spring 13 contraction). According to the judgment result of the tire size, if the tire is larger, the servo cylinder 5 is started to push the support plate 14 and the first fixed plate 11, so that the support frame 8 and the guide roller 2 are rotated under the support of the rotating frame 6, and then the distance between the two sides of the protective sleeve 18 is adjusted to adapt to the tire size.
