ABSTRACT:
An improved multi-function hinge structure is disclosed. It contains: (a) two substantially symmetrical wing plates (20, 21), wherein each of the wind plates has a substantially rectangle-shaped notch (25) on an inner edge (31) thereof and a pair of round surfaces (32) separated by the rectangularly-shaped notch; (b) a connecting plate (23) received by the rectangle-shaped notches collectively; and a pair of pivots (26) for connecting the wing plates with the connecting plate together to form a hinge. The connecting plate is substantially rectangular in shape with two round edge surfaces (33) facing the wings plates, respectively. Each of the round edge surfaces of the connecting plate and a corresponding round surface of the wing plate are on the same circumference of a fictitious circle centered at a corresponding pivot, so as allow the hinge plates to turn from 0.degree. to 360.degree. relative to each other.
