The two ends of the spring are fixedly installed on the groove body and the clamping rod. The spring applies tension to the clamping rod. When the centrifugal force generated by the rapid rotation of the wheel body is greater than the centrifugal force of the spring, the clamping rod opens outward and clamps on the groove body to achieve the braking effect. The spring can prevent the clamping rod from being affected by gravity and the clamping rod is stuck in the groove body.
