A suction cup device having a compact axial suction cup installation and release mechanism including a suction cup within a concave housing, and a rotational drive member structured to operate on an external surface of the housing. A drive shaft is coupled to the suction cup and extends through an aperture in the housing, projecting above a drive surface axially aligned with the concave surface formed in the housing. The drive shaft extends through an aperture in the rotational drive member and includes an inclined drive surface that interacts with a fixed drive surface to pull a flexible portion of the suction cup into the housing when the rotational drive member is rotated relative to the housing.
