Lockable chuck

摘要

A locking chuck is provided with arms (50) that extend from the adjustment mechanism to a locking ring (34). The arms are biased against the teeth (38) of the locking ring (34). As the outer sleeve is rotated in the tightening direction, rearward axial force is applied to the locking ring (34), thereby locking the locking ring against the body (12) of the chuck. When the outer sleeve (46) is rotated in the loosening direction, the arms rotate the locking ring to unlock the locking ring from the body.
