摘要： A torque wrench device has a torque wrench structure which includes a substantially tubular handle, a head pivotally secured to on end of the handle through a pivot pin, a toggle link connected to the head, a thruster coupled to the head through the toggle link, and a spring which resiliently urges the thruster towards the head. The device also has a clamp mechanism which is provided on an end of the head of the torque wrench structure and capable of clamping stem portions of a variety of types of wrenches by a resilient force exerted by a spring. The torque wrench structure may have an adapter support portion formed on one end of the head integrally therewith. In such a case, the torque wrench structure can be used together with an adapter engaged and held by the adapter support portion in such a manner as to allow adjustment of the position of the fulcrum at which the adapter is held by the torque wrench structure.
