When the height and inclination of the foundation panel need to be adjusted, it can be operated by adjusting the vertical position of the leveling nut 123 on the screw rod 122.

Specifically, in this embodiment, as shown in Figure 9, the applicant found that most of the grounds are relatively hard, in order to improve people's comfort when exercising, as a further improvement of the present invention, the applicant added the leveling nut 123 and An elastic shock absorber 14 is also arranged between the support arms 71, and the elastic shock absorber 14 can be used as a cushioning part to greatly improve the comfort level of the athlete during exercise. Specifically, in this embodiment, the elastic shock absorber 14 The vibration device is preferably a shock-absorbing rubber pier. In addition to shock absorption, the rubber pad has a special function: it is convenient to check whether the sleeper has moved up and down in the later stage. Small or gaps appear, indicating that the sleepers are sinking. Of course, the elastic damping device can also be other structures, such as an elastic member of a skeleton structure, or a pier column shock absorber of a bridge structure, etc., as long as it can play a shock absorbing and buffering effect.
