A tool is provided for moving a first clamping or gripping member toward or away from a second facing clamping or gripping member, the tool having a double threaded drive shaft coupled to opposed threaded linkage driving members for causing the threaded linkage driving members to be driven toward or away from each other. As the threaded linkage driving members move closer, the resulting angle of the links becomes steeper, thus increasing the mechanical advantage of the clamping tool, enhancing clamping forces. A beneficial result is a clamping apparatus that requires less manual energy than a traditional clamp. Another beneficial result is provided if the same amount of energy is applied to the driveshaft as in a traditional clamp, the resulting clamping force is significantly higher. If the second clamping member is adjustable, it accommodates wide variations in thickness of an object positioned between the first and second clamping members.
