[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. At the construction site of a construction project, in order to prevent the dust generated during construction from affecting pedestrians outside the construction site, dust screens are often installed around the construction site to prevent the dust from spreading to the outside of the construction site.

[0003] For example, the utility model: "Dust-proof net for use in construction projects", with the announcement number: "CN214886040U", can effectively solve the problem that the dust-proof net used in traditional construction projects cannot be quickly installed and disassembled during use, resulting in a heavy burden on the staff, through the coordinated use of a first connecting frame, a second connecting frame, a first sleeve, a first connecting rod, a shell, a roller body, a connecting column and a net body. The device can conveniently store the protective net, can quickly achieve the installation purpose, and improves the construction efficiency. However, during the implementation of this patent, the overall height of the dust-proof screen is fixed and cannot be adjusted. The dust-proof screen cannot be adjusted to a specified height for use according to demand. When the dust is raised at a high height, it is easy to float directly over the dust-proof screen, thereby easily causing pollution to the outside of the construction site. Utility Model Content
