In its preferred form, the one-hand manipulatable drive mechanism is attachable to a commercially available bar clamp made according to Holman U.S. Pat. No. 2,815,778 dated Dec. 10, 1957. The drive mechanism includes a drive lever having an apertured portion which is pivotal on the bar and a handle, an apertured drive lever brake key juxtaposed to apertured portion of the drive lever, a compression spring slidable on the bar with one end engaging the drive lever brake key, and a retainer having one part which engages the other end of the spring and another part which is attachable to jaw carrier and holds the spring in a compressed condition biasing the apertured portion of the drive lever against the jaw carrier.
