Abstract
A rotating hinge capable of driving a screen to ascend or descend includes a fixed base and a rotating support base. The fixed base has a guide plate with external positioning grooves corresponding to internal positioning grooves for pressing the guide plate, a limit plate linked to the rotating support base and corresponding to the internal and external positioning grooves, and internal positioning protrusion and external positioning protrusion. When the rotating support base is rotating, the positioning grooves and positioning protrusions rise. After the rotating support base rises, a four-point contact can be maintained stably to prevent and resist vibrations. When the rotating support base is rotated to a predetermined position, the positioning grooves and positioning protrusions will match with each other, and the rotating support base will be descended to a position to improve the touch feel and stability of driving a screen to ascend or descend.
