Chuck

A chuck comprising:

• a tube comprising:
• a polygonal hole including a distance between two opposite facets thereof and a diagonal length between angles thereof;
• an axial hole in communication with the polygonal hole, the axial hole includes a diameter larger than the distance and smaller than the diagonal length, thereby providing shoulders between the polygonal hole and the axial hole;
• an orifice in communication with the axial hole;
• and
• an aperture in communication with the polygonal hole;
• a sleeve comprising:
• a passageway for movably receiving the tube;
• an annular groove in a wall of the passageway;
• a conical hole in communication with the passageway;
• a shuttle movable in and along the axial hole, wherein the shoulders keep the shuttle in the axial hole;
• a bead movable in the aperture, wherein the conical hole includes a wall for contacting a portion of the bead, thereby inserting an opposite portion of the bead in the polygonal hole;
• and
• a ball movable in the orifice, wherein the passageway includes a wall for contacting a portion of the ball, thereby inserting an opposite portion of the ball in the axial hole to stop the shuttle, wherein the annular groove is operable to receive the ball to allow the ball to completely move out of the passageway.
