Chuck with Locking Clutch

A chuck comprising:

• a plurality of jaws;
• a body configured to rotate with a drive spindle of a power driver, wherein the plurality of jaws are configured to rotate with the body about a center axis of the chuck, wherein the plurality of jaws are also configured to move relative to the body in an opening or closing direction;
• a nut comprising nut teeth, the nut being operably coupled to the jaws and configured to move the jaws relative to the body in the opening or closing direction;
• and
• a clutch including clutch teeth, the clutch being configured to move between a working position and a jaw actuating position;
• wherein, in the working position, the clutch teeth are engaged with the nut teeth to prevent movement of the nut relative to the body, and
• wherein, in the jaw actuating position, the clutch teeth are not engaged with the nut teeth and the nut is free to move relative to the body.

• and
• a clutch including clutch teeth, the clutch being movable by a user between a working position and a jaw actuating position, the clutch comprising a working position recess and a jaw actuation recess;
• a protrusion extending and biased in a radial direction away from the center axis of the chuck;
• wherein the clutch is configured to, in response to a user sliding the clutch into the working position, engage the clutch teeth with the nut teeth to prevent movement of the nut relative to the body and move the working position recess into engagement with the protrusion to maintain the clutch in the working position, and
• wherein the clutch is further configured to, in response to the user sliding the clutch into the jaw actuating position, disengage the clutch teeth from the nut teeth to permit the nut to move relative to the body and move the plurality of the jaws in the opening or closing direction to move the jaw actuating position recess into engagement with the protrusion to maintain the clutch in the jaw actuating position.
