Preferably, in this embodiment, in order to prevent the flap 1083 from rotating due to its own weight and automatically rotating to the lower side to be in the folded state without limitation, the effect of pushing the tire 110 is not well stressed, and meanwhile, in the downward folded state, the flap 1083 cannot be automatically folded upward without external force by the auxiliary element 1085, which will affect the transportation of the next tire 110. For this purpose, the flap 1083 is also provided with a self-locking mechanism for limiting the angle of rotation. The implementation mode of auto-lock structure in this scheme has the multiple: firstly, the self-locking structure comprises a protrusion arranged on the outer side wall of the sliding block 1082 and a guide groove arranged at the joint of the wing 1083 and the sliding block 1082, and the protrusion abuts against the groove surface of the guide groove to limit the wing 1083 to continue to rotate along the original rotation direction.

Preferably, the fixing portion is bent backward in a zigzag shape so that the contact portion and the joint of the wing 1083 and the slider 1082 are not in the same straight line. The contact is now parallel to the connection of the fin 1083 and the slider 1082, and the contact is located behind the connection of the fin 1083 and the slider 1082. When the tire 110 is placed at a position later than the wing 1083, the wing 1083 is in a horizontal state after being unfolded, and the contact part is relatively positioned at a position later than the connection part of the wing 1083 and the sliding block 1082, so that the tire 110 can be contacted in the process of being pushed forwards, and the compatibility of the wing 1083 for pushing the tire 110 is improved.
