Abstract
A mechanical torque wrench including a wrench body defining an elongated interior compartment and a wrench head including a bar extending therefrom being pivotally secured to a first end of the wrench body. A hand grip located on a second end of the wrench body and a set spring is disposed within the wrench body. A pawl is disposed between the bar and the set spring. Rotation of a dial screw in a first direction compresses the set spring and rotation in a second direction allows expansion of the set spring. A set ring is operatively connected to the dial screw and rotatable relative to the wrench body. A resistive element is coupled to the dial screw and produces an output signal that depends on a position of the dial screw relative to the resistive element. A processor converts the output signal into an equivalent torque value for display on a user interface. Application of a torque greater than the equivalent torque value to a workpiece causes the wrench head to pivot relative to the wrench body about the pivot joint.
