<p>The chuck has a main sleeve (4) axially fixed but rotatable about an axis on a chuck body. The sleeve formed centered on the axis has a set of angled forwardly open guides and respective clamping jaws displaceable in the guides. A pusher engaging with the jaws is displaceable relative to the body to shift the jaws forward. A coupling jaw threadedly engages a screw thread of the body to couple the coupling jaw to the pusher.</p> |
