[0020] The specific technical solutions of the utility model are further described below with reference to the drawings so as to be further understood by those skilled in the art without constituting a limitation on its rights.

[0021] Embodiment 1, refer to Figs. 1-2 A pneumatic automatic movable ladder, comprising;

[0022] The mounting plate 1 is formed into a substantially square plate structure, one side of the mounting plate 1 is provided as a fixed surface fixed to a wall, the other side is provided as a mounting surface, and a plurality of bolt holes are formed in the mounting plate 1;

[0023] A pair of support vertical plates 2 are formed into a substantially trapezoidal structure, the edges of which have rounded corners, and the two support vertical plates 2 are vertically fixed to the mounting surface of the mounting plate 1 in parallel to each other, the space between the two support vertical plates 2 forms a movable ladder accommodating space, and a movable ladder 3 for facilitating climbing is arranged in the movable ladder accommodating space, the movable ladder 3 is a general structure of a ladder, which can be made of metal material and can be selected according to the use requirements;
