AI Technical Summary
After prolonged use, the end of the existing luggage spring connects to the plastic wheel bracket, causing internal damage to the bracket and loss of shock absorption.
Buffer pads are set at both ends of the shock absorber spring, and the shock absorber spring moves between the buffer pads to avoid direct connection with the bracket. The rotational connection structure between the wheel shell and the bracket ensures that the shock absorption direction of the spring remains unchanged.
It effectively prevents damage to the bracket from the end of the shock absorber spring, maintains the shock absorption effect, and ensures the stability of the shock absorption direction during long-term use.

The two ends of the connecting shaft 5 are limited in the connecting hole 11 and the rotating hole 22 through the nuts respectively. The shaft diameter of the connecting shaft 5 is consistent with the hole diameter of the connecting hole 11 and the rotating hole 22, so that excessive shaking of the connecting shaft 5 in rotation is avoided. The hole diameter of the buffer hole 21 is greater than the shaft diameter of the connecting shaft 5, the shock absorbing spring 3 is movably sleeved on the outer wall of the connecting shaft 5 and arranged in the buffer hole 21, the diameter of the shock absorbing spring 3 is consistent with the hole diameter of the buffer hole 21, so that shaking of the shock absorbing spring 3 is avoided.
