[0013] 2. The threaded rod can be rotated by the knob, and the threaded rod rotation drives the threaded sleeve to move. The threaded sleeve can only move along the direction of the movable groove under the limitation of the movable block and the movable groove. The movement of the threaded sleeve drives the movement of the movable block, and the movement of the movable block drives the movement of the U-shaped support bracket, thereby adjusting the vertical position of the U-shaped support bracket, which is convenient for the docking of multiple ventilation ducts, convenient for construction personnel to install, ensures construction efficiency, and is easy to use.
