Outdoor walking machine for physical fitness

The utility model relates to the field of fitness equipment. The outdoor walking machine for physical fitness comprises a machine body, the device comprises guide damping fixing structures which are vertically arranged on a mounting plane in a bilateral symmetry mode. The upper end of the guide damping fixing structure is in water connection with a support mounting plate; the upper end of the supporting installation plate is provided with a variable damping operation walking structure through swing restraining structures which are vertically arranged in a bilateral symmetry mode. Impact and pressure in the vertical direction generated by walking are counteracted through the damping springs; the generated shaking is counteracted by the deformation of the rubber reset mounting block; the operation process of the device is stable; the noise is low, the impact is small, the service life is longer, the rotating damping coefficient of the synchronous rotating shaft is changed through rotating adjustment, the requir
