US Patent 11774032 Biaxal pivoting mechanism and angle adjustment device

A biaxial pivoting mechanism configured for connecting an object to a holder includes a mount component, a rotatable connector, a main body and a mount base. The mount component is configured to be fixed to the object. The rotatable connector is rotatably disposed on the mount component about a first axis. The main body is fixed to the rotatable connector. The mount base is configured to be fixed to the holder, and the main body is rotatably disposed on the mount base about a second axis not parallel to the first axis. The main body has a first surface, a second surface, and an accommodating space. The first surface is located closer to the rotatable connector than the second surface. The accommodating space extends to the second surface from the first surface. At least part of the mount base is located in the accommodating space.
