Claims

[Claims for Utility Model Registration] 1. A head having a fitting portion that fits into a bolt, an arm that is coupled to the head and performs a tightening operation on the bolt, and a tightening torque for the bolt that is at least partially fixed to the arm. a detection section that detects the torque, a comparison section that compares the detected torque value detected by the detection section with a set torque value and is activated when the detected torque value reaches the set torque value, and energization of the comparison section. A torque wrench equipped with a luminous body that emits light at times. 2. The detection unit includes a strain sensor attached to the head or a neck provided between the head and the arm, and an amplifier attached to the arm to amplify the output of the strain sensor.Claim 1 of the Utility Model Registration Claims Torque wrench as described. 3. The torque wrench according to claim 1 or 2 of the utility model registration claim, wherein the comparison part is attached to the arm. 4. The torque wrench according to claim 1 or 2, wherein the comparison part and the light emitting body are attached to the arm. 5. The detection unit and the comparison unit include a protrusion provided to protrude in the direction of the arm of a head rotatably connected to the arm, a spring stretched between one side end of the arm, and a spring stretched between the protrusion and the protrusion. The torque wrench according to claim 1, which is a registered utility model, and comprises a movable contact mounted thereon and a fixed contact mounted between the other end of the arm opposite to the movable contact.
