The retractable component actuator further comprises an automated drive mechanism operable to move the first engagement feature upward and downward relative to the fixed component when the first portion is fixed to the fixed component. Downward movement of the second engagement feature relative to the first engagement feature is constrained by the first engagement feature. Upward movement of the second engagement feature relative to the first engagement feature is unconstrained by the first engagement feature. The second engagement feature is upwardly and downwardly co-movable, relative to the fixed component, with the first engagement feature.
