The invention provides a self-adaptive adjusting mechanism of an airladder, a using method of the self-adaptive adjusting mechanism and the airladder, and belongs to the technical field of aviation technology comprehensive guarantee. The self-adaptive adjusting mechanism of the airladder comprises trundles, wheel forks, a movable cylinder, a rotating shaft and a spring cylinder; the rotating shaft is assembled in the movable cylinder through a bearing, the spring cylinder is fixedly connected with the upper end of the movable cylinder, and the inner diameter of the spring cylinder is larger than the outer diameter of the rotating shaft. The wheel forks are fixedly connected with the ends, away from the spring barrels, of the rotating shafts, the trundles are installed on the wheel forks, the spring barrels are fixed to the lower portion of the boarding ladder body structure, and the movable barrels are provided with clamping holes allowing the clamping pieces to penetrate through. The invention has better manufacturability and bearing capacity; the structure is simple, height adjustment can be automatically completed by means of gravity, and the height of the airstairs can be automatically adjusted to adapt to angle changes.
