  • Lockable chuck
    Publication number: 20060027979
    Abstract: A locking chuck is provided with arms that extend from the adjustment mechanism to a locking ring. The arms are biased against the teeth of the locking ring. As the outer sleeve is rotated in the tightening direction, rearward axial force is applied to the locking ring, thereby locking the locking ring against the body of the chuck. When the outer sleeve is rotated in the loosening direction, the arms rotate the locking ring to unlock the locking ring from the body.
