Abstract:
1. A torque wrench comprising: a wrench head configured to grip a fastener and apply torque to rotate the fastener about a fastener axis when the fastener is gripped by the wrench head, and the wrench head defining a wrench head plane that is normal to the fastener axis when the fastener is gripped by the wrench head; a handle; a torque lever coupled to and extending from the wrench head toward the handle along a length of the torque wrench; and a torque application arm coupled to the handle and extending along the length of the torque wrench toward the wrench head, the torque lever and the torque application arm contacting each other at a contact point, wherein a force applied to the handle is transferred to the wrench head via the torque lever and the torque application arm at the contact point; wherein the wrench head is hinged relative to a portion of the torque wrench including the handle, torque application arm, and torque lever, and the portion of the torque wrench including the handle, torque application arm, and torque lever is pivotable with respect to the wrench head plane, the torque wrench further comprising a linkage for coupling the torque lever to the wrench head, wherein pivoting of the portion of the torque wrench including the handle, torque application arm, and torque lever relative to the wrench head plane moves the contact point between the torque lever and the torque application arm.
