When it is necessary to store the rotating plate, supporting legs, and counterweights, the handle can be rotated in the opposite direction to lower the sliding rod. The lowering of the sliding rod will cause the limiting rod to descend. After the limiting rod descends to the outside of the limiting port, the rotating plate can be rotated. Then, rotating the handle will reset the limiting baffle and the limiting rod. The reset limiting rod can limit the rotating plate after rotation, thereby achieving the effect of limiting and fixing the stored rotating plate.

[0013] 2. This leg press device for physical education uses a handle. By rotating the handle, the handle drives the threaded cylinder to rotate. The rotation of the threaded cylinder drives the threaded rod to rise, and the rise of the threaded rod drives the leg press plate to rise, thereby achieving the effect of adjusting the height of the leg press plate.
