  • the torque tools on a usually arranged on the inside clamping unit, via which the torque to be transmitted is adjustable.
  • the clamping unit comprises a spring-loaded release mechanism for this purpose.
  • the required coil spring is disposed between the trigger mechanism and a spindle nut. By displacing the spindle nut, the coil spring is compressed or relaxed accordingly.
  • the spindle nut itself is mounted on a spindle, by the rotation about its own axis, the spindle nut is displaced.
  • the respective position of the spindle nut is a measure of the bias of the coil spring, it is coupled to a suitable display means.
  • the US 4 541 313 A discloses a torque tool having a tool shank and a handle disposed at an end portion of the tool shank. At an opposite end of the handle of the tool shank a tool head is arranged, which has a drive polygon with a ratchet wheel. Within the handle, the clamping unit is arranged, via which the respective release torque is adjustable by turning the handle relative to the tool shank.
  • the clamping unit has for this purpose a displaceable in the longitudinal direction of the tool shank spindle nut, which serves to bias the arranged between the trigger mechanism and the spindle nut coil spring.
  • 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 opposite to the tool shank non-rotatable intermediate ring is arranged with an external toothing. A lying in the region of the collar portion of the handle has two inwardly facing and opposing cams, wherein the elastically designed collar is displaced by the cams from its position and arranged in this area internal toothing with the outer toothing of the intermediate ring engages.
  • 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 display means is then moved over a suitably slender executed tool from its position in the longitudinal direction of the tool shank until the measured release torque matches the displayed release torque.
  • the display means In addition to an undesirable displacement of the display means, for example by a fall of the torque tool, in particular its too large displacement is a problem.
  • the display means usually with increased effort to be withdrawn from its position in the opposite direction.
  • adjusting the display means of torque tools offers room for improvement.
  • the present invention is therefore based on the object to improve a torque tool of the aforementioned type such that the adjustability of the display means relative to the spindle nut is simplified and specified and whose set position is fixed even when the torque tool is dropped.
  • a torque tool which has a tool shank and a handle disposed at an end portion of the tool shank.
  • a clamping unit is arranged, via which the respective release torque is adjustable.
  • the clamping unit has for this purpose a displaceable in the longitudinal direction of the tool shank spindle nut, which is at least indirectly coupled to a display means.
  • the currently set triggering torque can be displayed.
  • the spindle nut is coupled to the display means via an actuating unit.
  • the relative position of the spindle nut and the display means to each other via the adjusting unit in the longitudinal direction of the tool shank is variable.
  • the particular advantage consists in the adjusting unit connecting the spindle nut and the display means, via which the exact position of the display means relative to the spindle nut can be fixed and changed. The predetermined by the actuator relative distance between the spindle nut and the display means causes this does not change, for example, even in case of accidental collapse of the torque tool.
  • variable position of the display means relative to the spindle nut over the adjusting unit causes a simple way of adjusting, whereby the otherwise takes place against the holding force of a press fit displacement of the display means via a tool.
  • this also effectively prevents excessive displacement of the indicating means relative to the spindle nut.
  • the display means is cylindrical.
  • the display means has at least one scale on its outer circumference.

  • the display means has a receiving area for the setting unit.
  • the receiving area can also be arranged on the spindle nut.
  • the actuator itself is rotatably mounted within the receiving area.
  • the rotatable mounting of the setting unit within the receiving area means that the setting unit is indeed rotatable about its longitudinal axis, but is effectively held against a displacement in the direction of its longitudinal axis within the receiving area.
  • the actuating unit can not be displaced in the direction of its longitudinal axis relative to the receiving area.
  • the relative position between the spindle nut and display can be changed by the actuator is rotated, for example, about its longitudinal axis.
  • the receiving area here represents a fixed point, against which the actuator is not displaced.
  • the actuating unit In order to convert the rotational movement of the actuating unit into a relative displaceability between spindle nut and display means, the actuating unit preferably has a threaded portion with an external thread.

  • the first scale and the second scale are spaced from each other in the circumferential direction of the indicating means.
  • 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.

  • the handle is coupled to a spindle on which the spindle nut is mounted in the interior of the handle.
  • the spindle nut provided with a corresponding internal thread is displaceable by turning the spindle.
  • a rotation of the handle relative to the tool shaft causes the displacement of the spindle nut, whereupon the coil spring is compressed or relaxed in the interior of the handle and / or the tool shank. Due to the so varying spring load of the trigger mechanism, the preset release torque is transferable, for example, to a screw connection.
  • the invention provides that a Einstellkniller can be arranged at the end of the handle.
  • the handle itself is mounted rotationally fixed to the tool shank.
