A hinge mechanism for securing to the body of an electronic device. The hinge mechanism includes a fixing plate. A holding member and two latching members project from the base of the electronic device. An end of the holding member opposite to the base bends toward the at least one latching member to form a latching portion. Each latching member includes a connecting portion projecting from the base, a supporting portion bending from an end of the connecting portion opposite to the base, and a hook arranged at a side of the supporting portion opposite to the connecting portion. The holding member cooperates with the supporting portion to define a clearance for holding the fixing plate, the hooks cooperate with the holding member to secure the fixing plate to the body.
