Abstract
An extension mechanism includes a bracket, a carrier, a slidable member, and a covering plate. The bracket includes a plurality of first buckling portions and a plurality of second buckling portions. The carrier is configured to move along a first axis relative to the bracket. A fastening portion of the carrier is configured to clamp one of the first buckling portions. The slidable member moves in a sliding groove of the covering plate along a second axis. A hook portion of the slidable member is configured to clamp one of the second buckling portions. The covering plate is connected to the slidable member and stops an extension module located on the bracket, to prevent the extension module from dropping or loosening when the extension module is vibrated.
