1. A system comprising:
a computing device configured to be mounted in an enclosure; and
a locking mechanism coupled to the computing device, the locking mechanism comprising:
a jaw configured to abut a portion of the enclosure;
a transmission lever comprising an arm pivot at a first end and an actuating pivot at a second end;
an arm configured to rotate about the arm pivot in an opening direction and a closing direction, the arm being selectively decoupled from the transmission lever; and
a wedge configured to bias against the jaw and lock the jaw against the portion of the enclosure when the arm rotates in the closing direction,
wherein when the arm is coupled to the transmission lever, rotating the arm in the opening direction causes the transmission lever to rotate in the opening direction about the actuating pivot and releases the jaw from the portion of the enclosure, enabling the computing device to be removed from the enclosure,
wherein the transmission lever includes an unlocking slope configured to contact an unlocking surface on the wedge, wherein rotating the arm in the opening direction when the arm is coupled to the transmission lever releases the jaw from the portion of the enclosure by forcing the unlocking slope of the transmission lever against the unlocking surface of the wedge.
