Abstract (en)
[origin: CN102909670A] The present invention relates to a torque tool having a tool shaft (2) and a handle (3) arranged at an end section of the tool shaft. A clamping unit is arranged within the handle and/or the tool shaft. Through the clamping unit the corresponding release torque is adjusted. The clamping unit comprises a screw nut (16) in the tool bar (2) which can move in the longitudinal direction (X) of the tool shaft. The screw nut is at least coupled indirectly with a display element (9). The release torque can be displayed by the display element. The display element (9) has a first scale (10) and a second scale (10a). The first scale (10) and the second scale (10a) are spaced from each other in the circumferential direction of the display element (9) and are opposite to each other by shifting of 180 DEG in the circumferential side.
