A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has two cam wings, two tilting shafts and two actuating disks. The tilting shafts are mounted movably through the cam wings. The actuating disks are mounted respectively around the tilting shafts. Each actuating disk has an actuating protrusion sliding along the outer edge of the cam wing. When the cover is pivoted to a certain angle, the actuating protrusions slide at part of the cam wing having larger diameter to gradually lift up the cover so the cover is selectively distant away from the lid. Therefore, the shape of the electronic device does not need to be disfigured and the cover still does not bump against the lid.
