Biaxial pivoting mechanism and angle adjustment device

A biaxial pivoting mechanism, configured for connecting an object to a holder, comprising:

• a mount component, configured to be fixed to the object, wherein the mount component has an opening;
• a rotatable connector, rotatably disposed in the opening of the mount component about a first axis;
• a main body, fixed to the rotatable connector;
• a mount base, configured to be fixed to the holder, wherein the main body is rotatably disposed on the mount base about a second axis not parallel to the first axis;
• a pivot;
• and
• two fasteners;
• wherein the rotatable connector has a first surface, a second surface, and an accommodating space, the first surface of the rotatable connector is opposite to the second surface of the rotatable connector, the accommodating space of the rotatable connector extends to the second surface of the rotatable connector from the first surface of the rotatable connector, and at least part of the mount base is located in the accommodating space of the rotatable connector;
• wherein the main body has a first surface, a second surface, and an accommodating space, the second surface of the main body is opposite to the first surface of the main body, the accommodating space of the main body extends to the second surface of the main body from the first surface of the main body, the main body includes two side plates located at two opposite sides of the accommodating space of the main body, the side plates each have a pivoting hole, two opposite ends of the pivot are respectively inserted into the pivoting holes, the fasteners are respectively engaged with the two opposite ends of the pivot, the mount base is fixed to the pivot, such that the main body is rotatable with respect to the pivot and the mount base, and at least part of the pivot and at least part of the mount base are located in the accommodating space of the main body.

An angle adjustment device, comprising:

• a holder, comprising:
• a base;
• a stand, standing on the base;
• and
• a pivotable connector, pivotably disposed on the stand about a reference axis;
• an object;
• a pivot;
• two fasteners;
• and
• a biaxial pivoting mechanism, comprising:
• a mount component, fixed to the object;
• a rotatable connector, rotatably disposed on the mount component about a first axis;
• a main body, fixed to the rotatable connector;
• and
• a mount base, fixed to the holder, wherein the main body is rotatably disposed on the mount base about a second axis not parallel to the first axis;
• wherein 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, the main body includes two side plates located at two opposite sides of the accommodating space, the side plates each have a pivoting hole, two opposite ends of the pivot are respectively inserted into the pivoting holes, the fasteners are respectively engaged with the two opposite ends of the pivot, the mount base is fixed to the pivot, such that the main body is rotatable with respect to the pivot and the mount base, and at least part of the pivot and at least part of the mount base are located in the accommodating space.
