A pair of spring actuated and stepped pins are incorporated into the lower jack body and, when inwardly actuated, engage recessed locations configured along the stems in order to define an adjusted separation distance between the bodies. In a second variant, a rotatable gear is incorporated into one of the bodies and engages a pair of outer beveled gears, with additional gears actuated by the outer bevel gears and in turn engaging any of opposing teeth or threads configured into the extending stems in order to define an adjusted separation distance between the bodies.
