Structure introduction: Turn the knob to rotate the inner rotating groove. The buckle moves downward due to the path restriction of the limit groove and the rotation groove, pulling the bracket and the plate tire to contract to the center. The snow mode shrinks inward, the land mode expands outward, and the two modes switch to each other to facilitate riding.
