[0031] The sequence of mechanical actions of the entire device:
[0032] 1. During training, start the motor 49 to drive the right rotation shaft 30 to rotate, thereby driving the right pulley 29 to rotate, thereby driving the conveyor belt 15 to move, and the human body can stand on the conveyor belt 15 for running training. Rotating the lever 36 drives the front rotation rod 37 and the rear rotation rod 35 to rotate, thereby driving the front short shaft 42 to rotate, thereby driving the right front gear 41 to rotate, thereby driving the front lower gear 44 Rotating, thereby driving the front lower short shaft 43 to rotate, thereby driving the front sector gear 45 to rotate, thereby driving the rear short shaft 54 to rotate, thereby driving the right rear gear 53 to rotate, thereby driving the rear lower gear 52 rotates, thereby driving the lower rear short shaft 51 to rotate, thereby driving the rear sector gear 50 to rotate. At this time, the front sector gear 45 meshes with the front rack 48, so that the front foot 46 moves up and down, At the same time, the rear sector gear 50 meshes with the rear rack 28 to drive the rear foot 27 to move up and down, thereby adjusting the inclination of the entire device.
[0033] 2. Stop the motor 49, and stretch the front handle 38 and the rear handle 33 to perform arm strength training. The human body lies on the conveyor belt 15, and the feet are inserted into the foot fixing frame 14 to perform Sit-up training.
[0034] 3. After the training, turn the front rotation rod 37 and the rear rotation rod 35 counterclockwise to drive the front foot 46 and the rear foot 27 into the front groove 47 and the rear groove 55, respectively At the same time, the front stretch plate 40 and the rear stretch plate 32 rotate to enter the front groove 47 and the rear groove 55 respectively, while the foot fixing frame 14 rotates to enter the rotation groove 11, so The front rotating rod 37 and the rear rotating rod 35 are parallel to the base 10 after rotating, so that the entire device is effectively stored together.
