A hinge has a pintle, a stationary leaf, a first limiting washer, a first positioning washer and a second positioning washer. The stationary leaf is mounted rotatably around the pintle. The first limiting washer is mounted securely on the pintle adjacent to the stationary leaf and has a limit. The first positioning washer is mounted around the pintle, is connected securely to the stationary leaf and has a protrusion and a detent. The protrusion corresponds to and selectively abuts the limit of the first limiting washer. The second positioning washer is mounted securely on the pintle and has a detent being selectively attached to the detent of the first positioning washer. The rotating angle of the pintle relative to the stationary leaf is limited by the limit of the first limiting washer abutting the protrusion of the first positioning washer.
