Abstract
A device for holding a workpiece, the device comprising a base, a first jaw member, a movable jaw member, and features which allow the movable jaw member to be moved in large increments relative to the first jaw member in addition to features which allow the movable jaw member to be moved in smaller increments. The device can include a drive member operably engaged with the base and the movable jaw member such that the operation of the drive member can move the movable jaw member in small increments. The movable jaw member can include a connection member which can operatively engage the movable jaw member with the drive member. The connection member can be moved between first and second positions to disengage the movable jaw member from the drive member such that the movable jaw member can be slid relative to the first jaw member in large increments.
