Definitions

  • the invention designates an operating mode switching unit at least partially rotating and striking hand tool like a combi hammer according to the preamble of claim 1.
  • Such Switching unit is from document JP 9 239 675 A known.
  • a hammer drill has a non-rotatable on the guide tube Externally manually operable, axially displaceable sliding sleeve with switching claws on which the drifting guide tube in a first operating mode in relation to the housing, in a second operating mode without rotation and in a third operating mode driving bevel gear ring.
  • a chisel hammer has a two-part guide tube, which via axially engaging locking balls in both radially and a spring-loaded can be fixed from the outside, manually displaceable, rotatable sliding sleeve.
  • slip clutches are used in the power transmission line.
  • a rotary hammer has a spring-loaded slip clutch which, between the hollow, containing an axially striking piston, abortive guide tube, which is non-rotatably connected to the tool holder, and a driving bevel pinion ring which is rotatable on the guide tube is arranged. Via an axially displaceable sliding sleeve that can be operated manually from the outside, according to one Disengage in case of overload, the slip clutch can be re-engaged.
  • a hammer drill has one of two axially resilient against one another pre-tensioned interlocking clutch rings on existing slip clutch, which between the hollow, containing an axially striking piston, abortive guide tube and a driving, rotatable on the guide tube Sprocket is arranged, which manually via one from the outside in three operating modes switchable, additional intermediate shaft is driven.
  • the object of the invention is the simple implementation of one in three operating modes manually switchable operating mode switch unit of a hand machine tool integrated slip clutch.
  • An operating mode switching unit essentially has one for at least three operating modes at least partially rotating and striking hand tool one Slip clutch, which is between a hollow, axially striking percussion piston containing, abortive guide tube and a rotatable on the guide tube, driving sprocket is arranged, and via a manually switchable from the outside, axially displaceable switching element can be switched into different operating modes, at least in one operating mode, the guide tube is driven in rotation, the axially displaceable Switching element in a form-locking manner in a driving, non-rotatably mounted to the guide tube Coupling ring of the slip clutch engages.
  • the axially displaceable sliding sleeve is advantageously stepped radially, thereby creating an axial stop is designed for the sliding spring.
