[0002] The construction frame is also called scaffolding. The scaffolding is a working platform set up to ensure the smooth progress of each construction process. When building a house, the construction frame is convenient for the construction workers. In order to make it more flexible in use, an adjustable steel structure house construction frame is needed.

[0003] According to the description of a multifunctional construction frame for housing construction disclosed on the patent website (authorization announcement number: CN217840788 U), "the utility model relates to the technical field of construction equipment, and discloses a multifunctional construction frame for housing construction, including a support plate, both sides of the top of the support plate are bolted with brackets, the top of the bracket and both sides of the bottom of the support plate are bolted with two pulleys, the top of the support plate is provided with a movable plate, and the surface of the pulley is placed with a wire rope; the utility model starts the dual-axis motor to drive the second pulley to rotate, and then the second pulley drives the rotating rod to rotate through the cooperation of the transmission belt and the first pulley, so that the rotating rod drives the winding wheel to wind the wire rope, and then the wire rope drives the movable plate to move through the cooperation of the pulley, so as to facilitate the user to adjust its support height; when the movable plate of the utility model moves, the movable plate drives the slider to slide inside the slide groove, thereby effectively improving its lifting stability."

[0004] In view of the above description, the applicant believes that there are the following problems:
