[0002] During the construction of a building, in order to facilitate the construction of the building and to protect the construction workers, cantilever scaffolding is often installed and used on the outside of the building.

[0003] After searching, Chinese patent number CN216406104U discloses an adjustable cantilever scaffold for construction engineering, in which limit holes are provided on the outside of multiple groups of vertical poles, and the outside of the vertical poles forms a lifting structure with a pull-out pedal through a limit collar and a limit block. Moreover, by cooperating and disassembling the limit holes on the outside of multiple groups of vertical poles and the first limit pin, the user can adjust and fix the pull-out pedal at different heights. In addition, by setting two groups of hollow limit plates at the upper and lower ends of the vertical poles, the multiple groups of vertical poles can be strengthened to limit them, so as to avoid the displacement of multiple groups of vertical poles, thereby improving the stability of the device during use. However, in the above-mentioned patented product, the lifting and fixing of the cantilever scaffold is only achieved by screwing in screws.
