Definitions

  • the known power screwdrivers which are equipped with a piston-cylinder unit and do not have a ratchet for taking the ring insert in one direction of rotation and for freely turning back in the other direction of rotation, must be equipped with a relatively large-stroke piston-cylinder unit, which Rotates the ring element or the screw head by 60 ° or at least 30 ° with each stroke.
  • the power wrench according to the invention can be equipped with a short-stroke drive device, because the angle of rotation which the screw executes with each stroke can be as small as desired. The adjustment is made by turning the ring insert on the drive shaft.
  • the key head housing 10 also has a circular segment-shaped guideway 22 which is curved in a circle around the axis of the ring insert 11.
  • This guideway 22 consists of a cavity, the outer circumferential wall 23 and the inner circumferential wall 24 extend in a circular arc, while the side walls are flat.
  • the guideway 22 has a rectangular or square cross section.
  • the support element 27 is located in the circular arc-shaped guide track 22, is also curved in a circular arc and has a cross section adapted to the guideway 22.
  • the support element 27 can be displaced along the circumferentially completely closed guideway 22, so that its outer end 27 'can be moved out of the guideway 22 and thus out of the key head housing 10.
  • the outer end 27 'of the support member 27 is against a fixed support 20, for. B. against a wall or an adjacent screw head, in order to derive the reaction force generated during screwing.
