  • the object of the present invention is to provide a sliding sleeve that can be used regardless of the type of rotary drive for the screw in question and this both manual screwdrivers and screwdriver blades that are used directly in, for example, a cordless screwdriver. This object is achieved by the invention with the features of the main claim.
  • the sliding sleeve should also be positionable so that once given screw-in depths are not exceeded.
  • the shaft clamping device should have a clamping range between 4 to 7.2 mm, so that conventional diameters of screwdriver shafts can be equipped with one and the same sliding sleeve.

  • the sliding sleeve can of course also be used for polygonal drive shafts, provided that the shaft clamping device is also designed accordingly.
  • the sliding sleeve is constructed in two parts.
  • Both sleeves can be screwed together over the thread pairing.
  • the corresponding contact surface of the outer sleeve must then be equipped correspondingly conical smooth, so that the clamping tongues can create a form fit to the shaft of the screwdriver tool.

  • the inner sleeve or the outer sleeve are equipped with a magnetically effective support surface.
  • the ring magnet can be inserted, for example, in an annular groove on the sleeve end and is there fixed in a suitable manner, for example with adhesive.

Abstract

L'invention concerne un manchon coulissant (1) à monter sur la tige (2) d'un outil à tournevis (3). L'objectif de l'invention est de créer un manchon coulissant (1) qui peut être utilisé pour une vis correspondante sans tenir compte du type d'entraînement en rotation employé à la fois dans des tournevis manuels et dans des outils pour tournevis qui sont directement insérés dans un tournevis fonctionnant au moyen d'une batterie, par exemple. A cet effet, le manchon coulissant (1), en plus d'être coulissant, peut être placé de manière immobile dans une position axiale, dans laquelle la pointe de l'outil pour tournevis fait saillie hors de la surface (7) de retenue, présentant une efficacité magnétique, au moyen d'un mécanisme (8) de serrage de la tige.
