Definitions

  • the invention relates to an at least partially rotating hand tool device such as one Combination hammer with more than two different operating modes.
  • Combined hammers have one necessary to generate the rotating movement
  • the rotary drive is operated by the tool holder Tool spindle separated and this rotatably with the housing of the combined hand tool connected.
  • a combined hand tool device has a along the tool spindle sliding and rotatable shift sleeve with the tool spindle, which can be moved lengthways via a mode selector switch on one end face into a rotary drive pinion or engages on the other end face in a housing pinion, the latter being the Tool spindle locked in rotation against the housing.
  • a rotary hammer has to switch the tool spindle speed one that can be moved perpendicular to the tool spindle using a mode selector switch Coupling slide on, which optionally via an engagement cam designed as a pin two differently graduated gear pinions rotatably with the one in a tool spindle pinion engaging bevel pinion connects.
  • a non-rotatable locking of the tool spindle against the housing is not used for rotary hammers.
  • the object of the invention is the simple implementation of a Hand tool device with more than two switchable operating modes.
  • the tool spindle in addition to a second operating mode in another, through which the mode selector switch, clutch slider of the combined hand tool switchable, third operating mode, the tool spindle rotatably with respect to the Locked the housing by in this switching position the engagement cam with housing-side, advantageous sectoral, recesses is engaged.
  • the tool spindle is preferably freely rotatable, by the engagement cam being rotatable in a free space in this switching position.
  • the fourth switching position is preferably between the second and the third switching position arranged.
  • the first and the second switching position are rotating operating modes assigned different speed.
  • the handheld power tool switchable third operating mode 2b becomes the tool spindle 3 locked in rotation with respect to a housing 5, in that in the third operating mode 2b assigned switching position a switching pin designed as an engagement cam 6 with a housing-side sectoral recess 7 is non-rotatably engaged.
  • a switching position assigned to a fourth operating mode 2c is the rotating engagement cam 6 surrounding free space 8 is formed.
  • the clutch slide 4 is perpendicular to Tool spindle 3 arranged and rotatably with a in a tool spindle pinion 9th engaging bevel gear 10 connected.
  • the clutch slide 4 rotatably and offset axially movably connected with stepped gear pinions 11, which a different speed in the first and the second rotating operating modes assigned.
