A rotatable hinge has a lower bracket, an upper bracket, a pivot shaft and a pivot pin. The upper bracket is mounted above the upper bracket and has a connecting wall formed on the upper bracket and has a riveting hole. The pivot shaft is mounted with the upper bracket and the lower bracket and has an enlarged end mounted on the upper bracket. The pivot pin rotatably extends through the riveting hole and has a limit mounted securely around the pivot pintle. The limit has a protruding section to control the cover to be rotatable at a specific angle.
