Definitions

  • the invention refers to a stirring tool, for example, for mixing paints or screed in the construction industry, which can be connected via an insertion end to an at least partially rotating hand tool machine, in particular a hammer drill.
  • stirring tools on a rigid elongate shaft, at one end of a radially projecting stirring means (stirrers, stirring blades, agitating loops, etc.) is formed and at the other end of a torque transmitting connection formed with the tool holder of a rotary power tool insertion end is present.
  • a radially projecting stirring means stirrers, stirring blades, agitating loops, etc.
  • a disadvantage of such stirring tools is the adhesion of the viscous material to be mixed to the agitator, in particular after completion of appropriate use when the stirring tool is to be cleaned.
  • the object of the invention is the realization of a stirring tool which better supports the cleaning of the same after appropriate use.
  • a stirring tool on a rigid elongated shaft at one end of a radially projecting stirring means is formed and at its other end for torque-transmitting connection with a tool holder of a rotary power tool suitable insertion end is formed, which has at least one axially closed on both sides locking groove.
  • the insertion is designed according to commercial impact tool insertion ends, in particular according to the SDS-Plus-Einsteckendes with 10mm guide diameter and two circumferentially opposite, frontally open trapezoidal rotary drive grooves and locking grooves closed on both sides, or the SDS-max-Einsteckendes with 18mm guide diameter and two circumferentially opposite on both sides closed locking grooves and three frontally open trapezoidal rotary driving grooves, whereby the stirring tool is used in common impact tool receptacles.
  • a stirring tool 1 a rigid elongated shaft 2, at one axial end of a radially projecting stirrer 3 is formed and at the other end of a male end 4 is formed, which has an axially closed on both sides locking groove 5 and frontally open rotary driving grooves 6.
  • Fig. 2 has the spigot 4 exactly two circumferentially opposite, closed on both sides locking grooves 5 and exactly two circumferentially opposite frontally open rotary driving grooves 6.
  • Fig. 3 has the insertion 4 'exactly two circumferentially opposite, closed on both sides locking grooves 5 and three frontally open rotary driving grooves 6.
  • Fig. 4 has the insertion end 4 "exactly two circumferentially opposite, closed on both sides locking grooves 5 and exactly two frontally open rotary driving grooves 6, one of which is formed deeper and the other wider.
