A clamping apparatus for clamping a workpiece, comprising: a clamp body, the body having a first end with a contact point and an opposing handle end defining a sleeve aligned with the contact point; a plunger sized to slide within the sleeve toward and away from the contact point; advancing means for moving the plunger toward the contact point, the advancing means having a first end defining an opening through which the plunger extends and a second end spaced apart from the plunger; trigger means pivotally mounted to the handle end for pressing the second end of the advancing means toward the contact point when the trigger means is squeezed, the advancing means when so pressed wedging against the plunger to move the plunger toward the contact point; retracting means for urging the second end of the advancing means toward the handle end when the trigger means is released, the advancing means when so moved sliding freely relative to the plunger ; locking means for maintaining the plunger in place after it has been moved by the action of the trigger means and advancing means, the locking means having a first end defining an opening through which the plunger extends, a second end spaced apart from the plunger, and a bias means urging the second end away from a position perpendicular to the plunger to allow movement of the plunger toward the contact point but to prevent movement of the plunger away from the contact point; and release means for urging the second end of the locking means toward a position perpendicular to the plunger to allow for movement of the plunger away from the contact point.
