Abstract
A torque wrench assembly comprises a torque wrench and a reaction arm and locking means for locking together the torque wrench and the reaction arm. The locking means comprises a connection member located on the torque wrench; an opening on the reaction arm for receipt of the connection member of the torque wrench; a locking member slidably mounted in a channel on the reaction arm, the locking member including an aperture sized to allow the connection member to pass therethrough; and biasing means arranged to bias the locking member into a position wherein the aperture is partially aligned with the opening. The connection member has an insertion end for insertion into the opening of the reaction arm, and immediately adjacent the insertion end is a recess. The recess is shaped to receive a part of the locking member.
