Abstract: A hinge is adapted to an electronic device having two screens. A base body of the hinge is mounted to a host base of the electronic device. The base body includes an operating portion and a linkage portion connected to each other. A first screen of the two screens is connected to the operating portion; a second screen of the two screens is connected to the linkage portion. The first screen rotates according to an operating part of the operating portion, and a driver assembly of the hinge simultaneously drives the operating portion and the linkage portion to rotate, so that the first screen and the second screen rotate simultaneously. By the simple hinge linkage structure design, the two screens rotate in opposite directions when being open, and may provide parallel slopes for viewing when being open to a preset open angle, thereby enhancing the convenience and smoothness of operation.
