Patent ID: 7380314

Claim:
A hinge adapted for rotationally coupling a cover and a body of a mobile phone about two perpendicular axes comprising: a transverse shaft adapted to be assembled with said cover; a vertical shaft extending perpendicularly from one end of the transverse shaft, the vertical shaft being adapted to be assembled with said body; and a locking mechanism being fixed on the other end of the transverse shaft, said locking mechanism including: a housing having a side wall, a top wall and a bottom wall which enclose a holding space, the side wall defining a cam slot having two ends with one end more distant from the top wall than the other end, the top wall defining a shaft hole; a locking bolt having a locking shaft and a sliding shaft being connected to and protruding perpendicularly from the locking shaft, the locking shaft being disposed in the holding space with an end thereof extending into the shaft hole, the sliding shaft passing through the cam slot and sticking out of the side wall; and a biasing member disposed between the bottom wall of the housing and the locking shaft for resiliently biasing the locking shaft; whereby when the sliding shaft slides along the cam slot, the locking shaft is driven to stick out of the top wall through the shaft hole so as to be received in a locking hole of said body for locking the transverse shaft to said body or retract from said locking hole into the shaft hole for releasing the transverse shaft from said body.
