A hinge mechanism for pivotally connecting a flip onto a housing includes a bush, a compression spring, and a release button. The bush has a sidewall, a receiving space defined by the sidewall, and a protrusion. The protrusion is protruded from the sidewall. The release button has a shaped notch, which includes a concave portion, a stop portion, and a convex portion formed between the concave portion and the stop portion. The stop portion extends substantially parallel to the pivoting axis. The protrusion is slidably received within the shaped notch. The compression spring is disposed within the receiving space and pressed by the release button and the bush. When closing the flip, the bush rotates synchronously with the flip and the protrusion moves in the shaped notch. When pushing the release button, the flip opens automatically.
