Then, the user steps on the right foot pedal 15 with the right foot, the right foot pedal 15 moves downwards from the initial position to compress the spring 16, and simultaneously the lifting mechanism moves downwards synchronously along with the right foot pedal 15, because the incomplete gear 21 is mounted on the rear wheel frame 12 and the fixing frame 102 of the base 1 through the first shaft 24, the right foot pedal 15 drives the incomplete gear 21 to rotate anticlockwise around the first shaft 24 through the connecting rod 20, the duplicate gear 22 externally meshed with the incomplete gear 21 rotates clockwise, the gear 23 externally meshed with the duplicate gear 22 rotates anticlockwise, and the driving shaft 25 rotates anticlockwise to drive the rear wheel 13 to move forwards. When the right foot board 15 moves from the initial position to the final position (i.e., the lower limit position), the driving shaft 25 rotates by half a turn, in the process, the left foot is lifted upwards, the left foot board 15 reaches the initial position from the final position, and thus the left and right foot boards 15 are repeatedly and alternately stepped on to complete the exercise. It should be noted that the gear 23 is connected to the driving shaft 25 by a ratchet mechanism (not shown) including a ratchet wheel and a pawl, wherein the ratchet wheel is mounted on the driving shaft 25, and the pawl is mounted on the gear 23, so that the pedal plate 15 is prevented from being reversed during the resetting process, i.e., from the end position to the initial position.

Referring to fig. 3 and 6, the brake device further comprises a brake mechanism, the brake mechanism comprises a brake plate 26 and a brake lever 28, the brake plate 26 is fixedly mounted on a second shaft 27, the second shaft 27 is rotatably mounted on the base 1, a torsion spring is arranged between the second shaft 27 and the base 1, the front end of the brake lever 28 is hinged to the brake plate 26, the rear end of the brake lever 28 is fixedly connected with a guide sliding rod 29 and an arc-shaped brake plate 30 in sequence, and the guide sliding rod 29 is slidably arranged in a guide sliding block 103 at the lower end of the base 1. It should be noted that the torsion spring (not shown) is provided between the second shaft 27 and the base 1 to enable the brake mechanism to have two independent operating states, one is a natural state and the other is a braking state, and the brake mechanism can be reset to the natural state after the braking state is released. When braking is needed, the brake plate 26 is stepped on by foot, the brake plate 26 drives the brake rod 28 to move backwards, and further drives the guide slide rod 29 fixedly connected with the brake rod 28 to move backwards along the guide slide block 103 until the arc-shaped brake plate 30 brakes the rear wheel 13. The brake mechanism returns to a natural state under the restoring force of the torsion spring after the brake is released.
