[0036] Specifically, during use, when the vehicle loses control and collides with the support frame 11, the anti-collision plate 16 blocks the front end of the vehicle. The vehicle will push the anti-collision plate 16 backward, thereby squeezing the buffer spring 15. The impact force is reduced by the cooperation of multiple groups of buffer springs 15.
