[0001] The utility model relates to the technical field of decoration auxiliary tools, in particular to an escalator for indoor decoration. Background Art

[0002] During interior renovations, ladders have become indispensable tools, greatly improving work efficiency for everything from applying wall paint to installing suspended ceilings. Similarly, during lighting maintenance, ladders allow maintenance personnel to easily reach overhead fixtures for replacement or commissioning. And during daily cleaning, ladders provide a convenient way for cleaning crews to ascend, freeing them from the confines of ground-level cleaning. These ladders not only provide convenience in various situations but also ensure worker safety, making aerial work easier and more efficient.

[0003] However, the existing decoration escalator is not equipped with a length adjustment structure when in use. When the escalator is short, it is difficult for construction workers to carry out construction operations at higher positions. When the escalator is long, it is difficult to enter the resident elevator and increases the difficulty of transportation. In addition, there is no structure to improve the stability of the escalator. When in use, it is often necessary to manually support the lower end of the escalator to keep it stable, and the convenience of use is not high.

[0004] Therefore, those skilled in the art provide an escalator for indoor decoration to solve the problems mentioned in the above background technology. Utility Model Content
