Abstract:
The present invention concerns a mixing shaft comprising a tool holder and a mixing blade, wherein the tool holder has a recess in which a portion of the mixing blade is fixed. To provide a simple mixing shaft, there is proposed a clamping portion fitted into the recess for fixing the mixing blade portion in the recess, wherein the clamping portion, the recess and the mixing blade portion are of such a configuration that a force-locking connection of the mixing blade in the recess is implemented by means of the clamping portion.

Claim (Index 19):
A mixing shaft comprising a tool holder and a mixing blade ( 3 ), wherein the tool holder has a recess in which a portion of the mixing blade ( 3 ) is fixed, wherein there is provided a clamping portion ( 11 ) fitted into the recess for fixing the mixing blade portion in the recess, wherein the clamping portion ( 11 ), the recess and the mixing blade portion are of such a configuration that a force-locking connection of the mixing blade ( 3 ) in the recess is implemented by means of the clamping portion, wherein the recess has a first and a second recess portion, wherein the mixing blade portion is arranged in the first recess portion and the clamping portion ( 11 ) is arranged at least partially in the second recess portion, wherein the tool holder has an axis of rotation and the mixing shaft ( 1 ) is adapted to be rotated about the axis of rotation, wherein the second recess portion is arranged in the axial direction beside the first recess portion, characterised in that the clamping portion ( 11 ) is supported both at the mixing blade portion and also at a wall of the second recess portion, wherein both the clamping portion ( 11 ) and also either the mixing blade portion or the wall of the second recess portion have mutually corresponding wedge surfaces ( 13 ), or the clamping portion ( 11 ) is of a two-part structure and the two parts of the clamping portion ( 25 ,  26 ) have mutually corresponding wedge surfaces ( 27 ).
