Description

Technical Field

[0001] The utility model relates to the technical field related to stair installation, and more specifically, to an auxiliary device for installing an assembled staircase. Background Art

[0002] Stairs are a type of vertical transportation facility in a building, used to connect spaces on different floors. They usually consist of a series of continuous steps (or steps) connecting platforms (also called resting platforms) between floors. The design and function of stairs vary depending on the purpose of use, spatial layout and aesthetic requirements of the building. However, there are some problems with the general stair auxiliary installation equipment on the market. They are usually not convenient for adjusting the length of the device, nor can they flexibly adjust the angle of the device according to the inclination of the stairs. This results in that during the installation process, the operator may need to make cumbersome adjustments according to different stair sizes and inclinations, which increases the difficulty and time cost of installation. In addition, many stair auxiliary installation devices cannot be conveniently folded and stored after use, which not only takes up valuable storage space, but also increases the difficulty of transporting and handling the equipment. Therefore, the practicality and stability of these devices are limited. Utility Model Content
