The chuck, comprising a central component (2) that fixes at the back to a driven shaft and interacts at the front with jaws (16), a rotating member and a locking ring (18), has an aperture (13) in the rotating member to receive a locking pawl (35) that is able to engage with the cogged surface of the central component. The pawl is engaged or disengaged by an actuator (26) located between the central component and locking ring and having a lug (28) that interacts with the pawl. |
