ABSTRACT:
A torque rod of variable length permits use of a torque wrench in confined quarters since the distance between the wrench and unit being tightened may be readily adjusted. A sleeve with a non-circular hollow receives a hollow stem carrying a ball detent which fits into any of a series of depressions in the sleeve wall. Within the stem is a pin with a bevel on its inner end. By moving the stem, the bevel forces the ball in or out to permit the stem to be moved in or out relative to the sleeve. A cam determines motion of the pin.
