The user can change the height of the bottom support plate by telescopically adjusting the length of the vertical hanger, so that the ventilation duct can be installed at different heights according to different needs. When the ventilation duct has obvious up and down slope paths, the user can change the angle of the bottom support plate by rotating the angle adjustment axis so that the bottom support plate can be tilted and contact and provide support for the ventilation ducts with slope paths. In actual use, the versatility of the mounting bracket is effectively improved, and the problem that the structural design of the existing mounting hanger usually lacks flexible adjustment functions, and the height and angle cannot be easily adjusted according to the installation position and shape of the ventilation duct, affecting the installation efficiency and effect, is effectively solved.

[0005] Furthermore, a plurality of limit screws are installed between the angle adjustment shaft and the bottom support plate, and the installation directions of the limit screws are opposite, and the number of the limit screws is eight in total. When in use, the plurality of limit screws installed in opposite directions can make the connection between the bottom support plate and the angle adjustment shaft more compact, and prevent the bottom support plate from falling off.

[0006] Furthermore, a plurality of anti-skid pads are fixedly mounted on the bottom support plate, and the anti-skid pads are provided with anti-skid patterns, and the vertical suspension rods are provided with scale lines. When in use, the anti-skid pads can contact the ventilation duct, further increasing the friction between the ventilation duct and the bottom support plate, and at the same time, the scale lines can enable the user to more intuitively observe the telescopic length of the vertical suspension rod when telescoping the vertical suspension rod.

[0007] Furthermore, a plurality of damping plates are fixedly mounted on the top of the mounting top plate, expansion screws are arranged on the threaded holes of the top plate, and the main material of the damping plates is chloroprene rubber. When in use, after the mounting top plate is mounted on the ceiling, the damping plates will directly contact the ceiling and provide a damping function for the mounting frame, and the damping plates are made of chloroprene rubber, which has better mechanical properties.

[0008] Furthermore, two telescopic connecting rods are fixedly connected to the side of the mounting top plates close to each other, and the telescopic connecting rods are both telescopically adjustable.
