A locking mechanism, for fixing and positioning a workpiece, includes a base, a locking member, a retaining plate, and an elastic member. The base defines a through mounting hole. The locking member comprises a main body, a blocking portion, and a latching portion. The blocking portion and the latching portion are respectively formed on opposite ends of the main body. The retaining plate is mounted on the base by the at least one locking member, and defines a through first opening corresponding to the mounting hole. The main body passes through the mounting hole and the first opening, the elastic member resists against the base and the blocking portion, such that the latching portion is engaged with and latched with the retaining plate by an elastic force of the elastic member.
