As an improvement, the LED lamp belts are arranged on the side face of the trapezoidal base and outside the connecting plate, and the arrangement of the LED lamp belts can enable a trainer to see the position of the springboard more clearly, so that the trainer is prevented from stepping on the air and falling down.

As an improvement, the bottom of the trapezoidal base is provided with anti-slip stripes, so that the springboard is prevented from sliding during training, and the design is safer and more reliable.

As an improvement, the trapezoidal base is provided with a notch at the position corresponding to the round rod, so that the round rod is convenient to install.

As an improvement, the rotating blocks are arranged into two pairs and symmetrically distributed, and the number of the springs III can be selected according to the actual use condition.

As an improvement, the surface of the springboard is provided with a non-slip mat, so that the friction between the sole of a trainer and the springboard is increased, and the sole is prevented from slipping and falling.

As an improvement, the size of the rectangular groove in the rectangular frame is matched with that of the rectangular block.

Compared with the prior art, the utility model the advantage lie in: trapezoidal base anti-skidding stripe can increase the area of contact and the frictional force that springboard and ground were played in track and field training, prevents to slide, through the round bar, solid fixed ring, the turning block, the spring three, the cooperation of rectangular block and rectangular frame can select suitable resilience force according to trainer weight and actual need, and the range of application is wider, and the lamp area of setting also plays better striking effect, prevents that the trainer from stepping on empty and fall and hinder.
