1. An apparatus comprising:
a frame including a first retaining pin;
a dial including a curved extension, the dial rotatable about an axis with respect to the frame, and movable along the axis to a retracted position and to an extended position with respect to the frame, the curved extension being curved about the axis and including a first catch corresponding to the retracted position;
a spring urging the dial toward the extended position;
a tooth attached to a leaf spring, the leaf spring attached to the frame and configured such that when the leaf spring is in a relaxed state the tooth is in a recessed position, wherein:
movement of the dial from the extended position to the retracted position causes the curved extension to deform the leaf spring, causing the tooth to move from the recessed position to an engaging position;
the first retaining pin when engaged with the first catch reversibly maintains the dial in the retracted position; and
movement of the dial from the retracted position to the extended position lessens the deformation of the leaf spring caused by the curved extension, causing the tooth to move from the engaging position to the recessed position.
