Abstract
The torque wrench (1) comprises a torque instrument (10) which is known per se--in the present case a ratchet instrument--as well as a torque indicator (40) which can be attached thereto. The torque indicator (40) possesses a sleeve-shaped support (41) which can be pushed onto the handle (12) of the torque instrument (10) and on which a linearly elastic bending rod (51) is fastened. Upon operation, the force (F) is exerted upon the free end of the bending rod (51) and the torque generated is displayed on a graduation (48). At its very front the support (41) possesses a non-rotationally symmetrical insertion zone (42) which receives the transition region (121) of the handle (12) in a manner fixed against rotation. The principal advantages of the torque wrench (1) are its dismantlability and the combination possibilities. The display accuracy of the torque indicator (40) is checked using a special test device.
