Cam-locking system for a retractable driveshaft and method for use thereof

A method of locking and disengaging a driveshaft, comprising:

• providing a cam-locking system, comprising:
• a housing having a first end, an opposite second end, an interior surface extending from the first end to the second end, and a central axis;
• a cam carrier located at least partially within the housing, the cam carrier being configured to translate relative to the housing along the central axis, wherein translation of the cam carrier is configured to cause translation of the driveshaft;
• and
• a cam rotatably coupled to the cam carrier;
• advancing the cam carrier along the central axis from a disengaged position to a first location;
• backing the cam carrier from the first location along the central axis until contact between the cam and the interior surface arrests the backing at a locked position;
• advancing the cam carrier from the locked position along the central axis to a second location past the first location;
• and
• backing the cam carrier from the second location along the central axis past the locked position to the disengaged position.
