Apparatus comprising a multi-motion assembly (206), the multi-motion assembly comprising:
a screw nut (307) having an inside thread that matches an outside thread of a leadscrew (202);
a clutch sub-assembly (410) connected to the screw nut, the clutch sub-assembly adapted to operate in any one of an engaged state and a disengaged state, wherein:
in the engaged state, the clutch sub-assembly prevents the screw nut from rotating with the leadscrew, such that rotation of the leadscrew causes linear movement of the screw nut; and
in the disengaged state, the clutch sub-assembly allows the screw nut to rotate with the leadscrew, such that rotation of the leadscrew causes corresponding rotation of the screw nut. |
