Abstract
An improved adjusting torque wrench includes an adjusting screw that is utilized for the purpose of changing the torque setting of the wrench. The screw has a radial flange thereon having a plurality of circumferentially spaced notches in the outer periphery of the flange. The adjusting screw is fixed to the grip member and rotatable therewith relative to an adjusting nut that is fixed in the lever arm of the wrench. A detent that is movable into and out of the recesses in the adjusting screw is slidably carried by the lever arm so that when engaged in the recesses, the detent prevents relative rotation between the grip member and the lever arm, and thus prevents adjustment of the torque. Also, the detent extends exteriorly of the gripping member so that it can be grasped by the operator of the wrench and moved out of the recesses so that the wrench can be easily adjusted to a new torque setting.
