In the process of the limit plate 19 driving the sliding rod 17 to slide inside the support plate 16, the strong spring 18 will be stressed, and then under the force of the strong spring 18, The rebound force can reduce the impact force generated by the contact between the wheel and the limiting plate 19, and can limit the wheel at the top of the fixed platform 1.
