A locking mechanism for selectively connecting a first locking member, the locking mechanism comprising: a base moveable towards a first direction and having a hole; a plate connected to the base and neighboring the hole; a pivot rotatable with respect to the plate and rotating between a first angle and a second angle, wherein the pivot is inserted through the hole and neighboring the plate, the pivot having a raised edge; and a second locking member connected to the base and for selectively engaging the first locking member; wherein when the pivot is positioned in the first angle, the raised edge extends substantially parallel to the first direction to abut against the plate to make the plate move towards the first direction, so that the second locking member is detachable from the first locking member; wherein when the pivot is positioned in the second angle, the raised edge extends substantially perpendicular to the first direction to be away from the plate to allow the second locking member to remain engaged with the first locking member.
