The present invention is directed to a locking mechanism for use in an external optical disk drive. The locking mechanism includes a switch supporting base, a push rod, a locking member and an electromagnetic switch. An elastic member is fitted to the push rod, and both ends of the elastic member are restrained by the push rod and the switch supporting base. To open the cover, the locking member disengages from the cover by the electromagnetic switch and the push rod pushes the cover upwardly due to the elastic member. To lock the cover, the push rod is restrained by the switch supporting base and the push rod does not contact the cover. Thus, there is no force applied to the cover, and the cover is simply restrained by the locking member.
