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, or claw, 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.

The workholding apparatus of claim 1, wherein said toggle further comprises: a detent member configured to releasably hold said toggle in said first orientation and said second orientation. 3. The workholding apparatus of claim 2, wherein said actuator comprises a spring-loaded plunger. 4. The workholding apparatus of claim 1, wherein said drive member comprises a rack including a plurality of notches, wherein said toggle comprises an engagement portion that is positioned within one of said notches when said toggle is in said first orientation, and wherein said engagement portion of said toggle is removed from said notches when said toggle is in said second orientation. 5. A workholding apparatus, comprising: a base comprising a support surface configured to support a workpiece, wherein said support surface comprises a first lateral side and a second lateral side;a first jaw member fixedly mounted to said base;a drive member operably engaged with at least one of said first jaw member and said base; anda second jaw member slidably engaged with said base, wherein said second jaw member comprises a selectively rotatable toggle positioned laterally with respect to said first lateral side of said support surface, wherein said toggle is rotatable between a first orientation and a second orientation, wherein said second jaw member is operably engaged with said drive member when said toggle is in said first orientation, wherein said second jaw member is operably disengaged from said drive member when said toggle is in said second orientation, and wherein the operation of said drive member in a first direction moves said second jaw member toward said first jaw member and the operation of said drive member in a second direction moves said second jaw member away from said first jaw member when said toggle is in said first orientation, wherein said toggle comprises:an actuator moveable between a locked position and an unlocked position; anda detent assembly configured to releasably hold said toggle in said first orientation and said second orientation. 6. The workholding apparatus of claim 5, wherein said toggle is at least partially positioned below said support surface. 7. The workholding apparatus of claim 6, wherein said actuator comprises a spring-loaded plunger. 8. The workholding apparatus of claim 5, wherein said drive member comprises a rack including a plurality of notches, wherein said toggle is positioned within one of said notches when said toggle is in said first orientation, and wherein said toggle is removed from said notches when said toggle is in said second orientation. 9. A workholding apparatus, comprising: a base comprising a support surface configured to support a workpiece, wherein said support surface comprises a first lateral side and a second lateral side;a first jaw member;a drive member; anda second jaw member slidable relative to said base, wherein said second jaw member comprises a selectively rotatable toggle lock, wherein said toggle lock is rotatable between a first orientation and a second orientation, wherein said second jaw member is operably engaged with said drive member when said toggle lock is in said first orientation, wherein said second jaw member is operably disengaged from said drive member when said toggle lock is in said second orientation, and wherein the operation of said drive member in a first direction moves said second jaw member toward said first jaw member and the operation of said drive member in a second direction moves said second jaw member away from said first jaw member when said toggle lock is in said first orientation, wherein said toggle lock comprises an actuator moveable between a locked position and an unlocked position, wherein said toggle lock is positioned laterally with respect to said first lateral side of said support surface, and wherein said toggle lock is at least partially positioned vertically below said support surface. 10. The workholding apparatus of claim 9, wherein said actuator further comprises a recess, and wherein said toggle lock comprises a lock element that is configured to slide into said recess when said actuator is in said unlocked position such that said lock element releases said toggle lock and permits said toggle lock to rotate to said second orientation. 11. The workholding apparatus of claim 10, wherein said actuator comprises a spring-loaded plunger. 12. The workholding apparatus of claim 9, wherein said drive member comprises a rack including a plurality of notches, wherein said toggle lock is positioned within one of said notches when said toggle lock is in said first orientation, and wherein said toggle lock is removed from said notches when said toggle lock is in said second orientation. 13. The workholding apparatus of claim 1 further comprising a second toggle, wherein said second jaw member is configured to slide along a path, and wherein said toggle and said second toggle are laterally offset from said path. 14. The workholding apparatus of claim 1 further comprising a support surface configured to support a workpiece, wherein said support surface is positioned vertically above said drive member. 15.
