[0041] The ladder assembly 40 comprises a first ladder body 41 and a second ladder body 42, which are vertically arranged and parallel to each other. The first ladder body 41 and the second ladder body 42 of the present embodiment form an angle with the ground, so that the ladder assembly 40 has a certain inclination, facilitating climbing. A plurality of rungs 43 are arranged between the first ladder body 41 and the second ladder body 42, one end of each rung 43 being fixed to the first ladder body 41 and the other end being fixed to the second ladder body 42. The plurality of rungs 43 are linearly arranged between the first ladder body 41 and the second ladder body 42, forming a plurality of steps.

[0042] The first ladder body 41 forms a first ladder foot and a first ladder top at both ends, respectively. The first ladder foot is supported on the ground, and the first ladder top is used to be connected with the guide rod assembly 10. The second ladder body 42 forms a second ladder foot and a second ladder top at both ends, respectively. The second ladder foot is supported on the ground, and the second ladder top is used to be connected with the guide rod assembly 10.

[0043] The first suspension wheel assembly 20 is arranged between the first ladder top and the guide rod body 11. One side of the first suspension wheel assembly 20 is slidably connected with the guide rod body 11, and the other side is fixedly connected with the first ladder body 41. The second suspension wheel assembly 30 is arranged between the second ladder top and the guide rod body 11. One side of the second suspension wheel assembly 30 is slidably connected with the guide rod body 11, and the other side is fixedly connected with the second ladder body 42. Thus, the ladder assembly 40 can translate in the length direction of the guide rod assembly 10.

[0044] The embodiment sets the guide rod body 11 fixed on the high platform, sets the first suspension wheel assembly 20 to slide connect one side of the ladder assembly 40 to the guide rod body 11 on the high platform, sets the second suspension wheel assembly 30 to slide connect the other side of the ladder assembly 40 to the guide rod body 11 on the high platform, so that the ladder assembly 40 can translate in the length direction of the guide rod assembly 10. In use, the user can adjust the position at any time according to the needs, move the ladder assembly 40 to the required position to climb to the high platform, and when the ladder is not needed, the ladder assembly 40 can also be moved and stored in the corner or gap of the edge, reducing the space occupation of the ladder when not in use.
