ABSTRACT:
A workbench has at least one drive member to clamp table members against one another. The drive member has a receiving tube and a crank tube. The receiving tube and crank tube are coupled with respect to one another for telescoping movement. One of the tubes has a threaded member and the other tube has a thread engaging member. A mechanism engages and disengages the thread engaging member into the threaded member such that in an engaged position, the crank tube can be rotated in the receiving tube for screw type movement. In a disengaged position, the crank tube is freely slidable for sliding movement in the receiving tube.
