Fastening mechanism and electronic device having the same

A fastening mechanism for an electronic device, the electronic device including a shell body and a cover detachably coupled to the shell body, the cover having a first fastening structure, said fastening mechanism comprising:

• a press unit adapted to be provided on the shell body and including
• a press portion that is adapted to be exposed from the shell body and that is pressable to extend resiliently into the shell body to be disposed at a depressed state, and
• a second fastening structure fixed to said press portion, said second fastening structure being adapted to engage to the first fastening structure when the cover is coupled to the shell body to prevent removal of the cover from the shell body, and being adapted to disengage from the first fastening structure when said press portion is depressed to permit removal of the cover from the shell body;
• and
• a resilient component adapted to be provided in the shell body;
• wherein said resilient component stores a restoring force when the cover is coupled to the shell body, and releases the restoring force when said second fastening structure is disengaged from the first fastening structure for biasing the cover away from the shell body;
• and
• wherein said resilient component is a resilient plate, and includes a fixed plate portion adapted to be fixed to the shell body, and a movable plate portion that is configured to be in direct contact with the cover when the cover is coupled to the shell body so as to be directly compressed by the cover for storing the restoring force and that is resiliently deformable relative to said fixed plate portion for directly biasing the cover away from the shell body.
