The linkage mechanism 3 includes a first connecting rod 31 and a second connecting rod 32 that are movably connected to each other via pins. A foot pedal 33 is provided at the end of the second connecting rod 32. Elastic fixing mechanisms 4 are symmetrically arranged at the bottom of the foot pedal 33. The elastic fixing mechanisms 4 are used to adjust the position of the foot pedal 33 on the second connecting rod 32. By cooperating with the second connecting rod 32, the position of the foot pedal 33 is adjusted, thereby achieving the stride length adjustment and providing a wide range of adaptability.

[0027] In this utility model, the second connecting rod 32 is provided with multiple fixing holes 321; the elastic fixing mechanism 4 cooperates with the corresponding fixing holes 321; specifically, the elastic fixing mechanism 4 includes a fixing post 41, a pull rod 42 and a spring 43. The fixing post 41 is fixed to the bottom of the foot pedal 33, the pull rod 42 moves in the cavity of the fixing post 41, the spring 43 wraps around the outer wall of the pull rod 42, and the pull rod 42 extends into and passes through the corresponding fixing hole 321; a limiting plate 421 is provided on the outer wall of the pull rod 42, and the two ends of the spring 43 are respectively connected to the limiting plate 421 and the inner cavity of the fixing post 41. Through the cooperation of the pull rod 42, the spring 43 and the multiple fixing holes 321, the foot pedal 33 can be quickly unlocked and moved, thereby realizing the function of quickly adjusting the step distance, which is convenient to use.

[0028] In this utility model, the flywheel system 2 includes a pulley 21, a resistance magnetic control wheel 22, and a connector 23. The pulley 21 and the resistance magnetic control wheel 22 are fixed to the frame 1 at opposite positions by a rotating shaft.

[0031] The implementation principle of this utility model of an ultra-thin elliptical machine with a large step distance is as follows:

[0032] In use, pulling both levers 42 simultaneously quickly separates the levers 42 from the fixing holes 321 and retracts them into the fixing post 41, compressing the spring 43. Then, the sliding foot pedal 33 moves to the end of the second connecting rod 32, and the clamping block 331 clamps the end of the second connecting rod 32. When it moves to the appropriate position, the levers 42 are released, and the spring force of the spring 43 pushes the limiting plate 421 to move, thereby pushing the levers 42 into and through the fixing holes 321. The two levers 42 fix the foot pedal 33, and the clamping block 331 improves the stability of the foot pedal 33, realizing the function of adjusting the step distance. It is easy to use, has a good fixing effect, and is highly practical.
