A hinge includes a fixing member, a shaft fixed to the fixing member, a rotating member, an interfering member, and a fastener. The shaft includes a shaft post, and the fastener is fixed to a distal end of the shaft post. The interfering member defines a fixing hole departing from a center of the interfering member, and includes two guiding surfaces. The rotating member defines an oblong adjusting hole, through which the shaft post rotatably passes. A first resisting stub and a second resisting stub extend from the rotating member, to resist against the corresponding guiding surfaces. The shaft post is fixedly received in the fixing hole. When the rotating member is rotated relative to the shaft post, the first and second resisting stubs always resist against and move along the corresponding guiding surfaces, to urge the shaft post to relatively move in the adjusting hole.
