The adjustment mechanism can change the position of the ventilator 29 on the top of the car body 1, thereby avoiding ventilation dead corners and places with poor ventilation inside the car body 1, and improving the ventilation effect of the ventilator 29 inside the car body 1.
[0024] Furthermore, a shock absorbing mechanism is provided at the bottom of the car body 1, and the shock absorbing mechanism includes a damper 3, the damper 3 is fixedly connected to the surface of the car body 1, a shock absorbing spring 31 is fixedly connected to the surface of the damper 3, a bottom plate 32 is fixedly connected to the surface of the shock absorbing spring 31, and the telescopic end of the damper 3 is fixedly connected to the lower surface of the bottom plate 32.
