Abstract
A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may include a clamping assembly comprising a clamping member that operably couples the sleeve to a nut. The clamping assembly may be configured to transition the chuck between a rapid jaw adjustment mode and a clamping mode. In the rapid jaw adjustment mode, a sleeve may be configured to rotate the clamping member with the nut to cause rotational movement of the nut relative to jaws and a chuck body, which may cause translational movement of the jaws relative to the chuck body. In the clamping mode, the nut may be rotationally fixed with the jaws and the clamping member may rotate relative to the nut to cause the nut to move axially relative to a center axis of the chuck which causes the jaws to translate relative to the body and clamp onto a working bit.
