The present invention provides a mobile terminal having an inward-foldable flexible screen and its hinge comprises a left support plate, a middle support plate, a right support plate, a left support frame, a right support frame, and a central U-shaped cover; the middle support plate is a liftable plate whose position corresponds to the middle U-shaped cover, and the descent distance of the middle support plate in the first half of the hinge being folded from the unfolded state is greater than that of the second half of the hinge being folded from the unfolded state. The present invention can be used as the hinge of the mobile terminal with the flexible screen on the inside, and can quickly form the space for the flexible screen to be bent when folded, to avoid the flexible screen from being damaged, and to make the middle mechanism of the hinge not exposed after being folded.
