Hinge of infolding flexible screen mobile terminal

The invention provides a hinge of an infolding flexible screen mobile terminal. The hinge comprises a hinge middle shaft, a fixed seat, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a left side rotating arm connecting rod and a right side rotating arm connecting rod, the hinge center shaft is connected with the fixing base, the first connecting rod and the second connecting rod. A plurality of connecting rods are adopted as the hinge body, the rotating transmission function and the left-right synchronous reversing function are achieved, the rotating supporting plate and the hinge body are driven by the bias pressure spring and are in linkage with the hinge middle part, a screen containing space for the drop-shaped middle bent part of the flexible screen during flattening supporting and folding is provided, the overall structure is simple, and operation is convenient. A virtual rotating shaft structure is avoided, machining and manufacturing are convenient, t
