The drive shaft unit of a mixing apparatus has an outer shaft (28) and a moving inner shaft (30). One shaft is locked (54) with the mixing tool (16), in a force fit, relative to the direction of mixing tool (16) rotation. The other shaft is connected to the mixing tool shaft so that a relative rotation between the inner (30) and outer (28) shafts gives an axial lock for the mixing tool (16) at the drive shaft unit (18) through the mixing tool drive shaft. |
