QUICK-ACTION CLAMPS

摘要

A clamp which is operable with one hand includes a fixed jaw and a movable jaw. The movable jaw connects to one end of a movable slide. One-way drive means, by operation of a handle grip, releasably engages the slide and advance the movable jaw toward the fixed jaw. Return motion of the movable jaw is accomplished manually when the one-way drive means is disengaged. A braking lever, biased to bind against the slide bar, prevents reverse motion of the movable jaw except when disengaged from the slide. The handle advances the slide by driving a second lever which binds against a slide surface. The second lever returns by spring force to its original position after each stroke of the handle.
