[0020] In this embodiment, the bottom of the moving block 7 extends to the interior of the valve body 3, and a limiting groove 12 adapted to the moving block 7 is opened at the bottom of the inner cavity of the valve body 3. The outer side of the moving block 7 is in sliding contact with the inner cavity of the limiting groove 12. The corresponding side of the moving block 7 is fixedly connected with a first spring 11, and the first spring 11 is sleeved on the outer side of the limiting rod 6. The limiting rod 6 and the limiting groove 12 cooperate with each other to limit the moving block 7, thereby improving the stability of the left and right movement of the moving block 7.

[0021] In this embodiment, a first connecting seat 2 is fixedly installed on the right side of the top of the base plate 1, and an inclined plate 20 is rotatably connected to the inner cavity of the first connecting seat 2. A pad 19 adapted to the pulley 17 is fixedly installed at the bottom of the inclined plate 20, and an anti-slip pad 21 is fixedly inlaid on the top of the inclined plate 20. The anti-slip pad 21 improves the friction between the sole of the user's foot and the inclined plate 20, thereby improving the efficiency of stepping on the inclined plate 20.
