ABSTRACT:
A clamp usable as a vise has a fixed clamping member and a movable clamping member movable toward and away from the fixed clamping member along a guide. A tippable locking element has a hole through which passes an elongated locking element that extends in the direction of displacement of the clamping member. The tippable element can be displaced between a slide position wherein the hole loosely surrounds the elongated element and allows it to move relative to the tippable element and a locked position with the tippable element canted and the elongated element wedged in the hole. Furthermore once the tippable element is in the canted position it can further be displaced so as to bring extra clamping force to bear on a workpiece between the two clamping members.
