Torque wrench

摘要

An inexpensive torque wrench is installed on a particular object, such as an electrical cable connector, so that the object may be fastened to a counterpart by applying a torque that is within a predetermined torque range. The wrench is preferably formed as a single molded plastic unit. The wrench includes a ring-shaped collar and at least two fins extending outwardly from the collar on opposing sides thereof. The interior of the wrench is hollow and surrounded by an interior wall of the collar. The interior wall is dimensioned to tightly mate with the particular object on which it is installed. The fins are dimensioned to support the predetermined torque range and angled so that a slightly greater counterclockwise torque than clockwise torque may be applied. When the wrench is installed on the object, it may be removed by breaking off the fins so that the collar may then be separated into two halves. The two halves may then be disengaged from the object, thereby allowing a conventional open-end wrench to be used on the object in lieu of the torque wrench.
