Hinge capable of rotating in orthogonal directions

The utility model relates to a hinge capable of being rotated in orthogonal directions, which comprises a fixed connecting plate. A longitudinal rotation structure is formed in a way that a horizontal shaft which is arranged on one end of the fixed connecting plate is connected to one end of a long shaft, and a horizontal rotation structure is formed in a way that the shaft body of the long shaft vertically and movably extends in a movable connecting block. In the utility model, the fixed connecting plate and the movable connecting block are respectively in shaft connection with two pieces of orthogonal shafts which can be mutually rotated. Thereby, the movable connecting plate can horizontally rotate around a longitudinal shaft as well as can longitudinally rotate around a transverse shaft, and one pair of hinge can rotate in the orthogonal two directions, which is convenient for people to select opening direction.
