  • the handle has a tool shaft encompassing display means which includes a circumferential collar with an internal toothing. Between the collar and the tool shank, an intermediate ring, which is non-rotatable with respect to the tool shank, is arranged with an outer toothing.
  • An im Area of the collar lying part of the handle has two inwardly facing and opposing cams, wherein the elastically executed collar is displaced by the cams from its position and arranged in this area internal gear with the external teeth between ring comes into engagement.
  • the internal teeth and the external teeth have a different number of teeth, so that is rotated by a rotation of the handle, in particular the cam, the display means in the gear ratio thus generated relative to the handle.
  • the clamping unit further comprises the displaceable in the longitudinal direction of the tool shank spindle nut, which is at least indirectly coupled to a display means.
  • the currently set tripping torque can be displayed via the display means.
  • the parallel and at a glance to be detected arrangement of two different units of measurement offers the advantage of transnational use of the same torque tool.
  • one and the same components can be used without having to make the installation or even exchange of various display means.
  • the color-coded execution of the display means with respect to the different units of measurement clarifies to the user the difference between the displayed values.
  • the consequences that may result from this are an obvious problem, especially for glands with high safety requirements.
  • the present invention is therefore based on the object to improve a torque tool of the aforementioned type such that the risk of reading a false triggering torque in the arrangement of two different units of measure is reduced.

  • the invention provides that the first scale and the second scale have mutually different, in particular in each case country-specific units of measure for displaying the currently set release torque. As a result, a transnational applicability of the same torque tool is achieved in an advantageous manner. Due to the optical separation of the two scales, a possible risk of confusion with respect to the displayed on the respective units height of the triggering torque is effectively prevented.
