Definitions

  • Such a screwdriver with depth stop is from the US 4,655,103.
  • a screw With the known screwdriver, a screw can be placed on a with a depth stop preset screwing depth in screw in a surface. If the depth stop on the Surface closes, a clutch is switched off, with a largely silent shutdown.
  • a motor-driven drive wheel is provided, that with an axially movable intermediate wheel forms a first cam clutch.
  • the intermediate wheel acts on its other side facing the tool carrier with one another coupling element together, the oblique cam surfaces the assigned elements a second cam clutch form.
  • Driving elements in the form of straight axially parallel Flanks provided by which when a certain basic moment that associated with the tool holder Coupling element is taken from the intermediate coupling element.
  • there is between the drive wheel and the intermediate wheel a compression spring is arranged through which the idler gear in the direction is preloaded on the tool holder.
  • the depth stop is first set to the desired one Screw-in depth set and then the tool holder with his tool placed on a screw to be screwed in and pressed. This will get all three coupling elements with each other so that the torque from the drive wheel is transferred to the tool carrier if with the Screwing process is started. Due to the occurring torque the idler gear and the coupling element connected to the tool holder somewhat pushed apart until the straight drive flanks join together come into engagement and a form-fit entrainment guaranteed is. The depth stop runs on the surface the tool carrier moves with the tool holder and the screw further until this is complete is screwed in.
  • the invention is therefore based on the object of an improved power screwdriver with depth stop too create, either with a shutdown via depth stop or allows a torque-dependent shutdown and in both cases no rattling of the Shutdown clutch occurs.
  • the release ring is on the tool drive shaft secured against rotation and against the Resistance axially displaceable. Furthermore, one Locking device provided to the release ring in an axial advanced towards the tool holder hold when the release ring is axially in operation under load moves towards the tool holder, and around the Release ring after the disconnect clutch has tripped and then Relieve discharge again.
