[0013] Preferably, a plurality of universal ball bearings are evenly distributed at the lower end of the support member, and the lower ends of the universal joint balls of the universal ball bearings are all supported to the bearing surface.

[0014] By installing a universal ball bearing under the support component, stress generated during testing can be easily released. Simultaneously, the universal ball bearing facilitates wheel axle steering, enabling the vehicle to turn left and right under static driving conditions—that is, the wheel axle rotates while the vehicle body remains stationary.
