The present invention relates to a mixing tool holder (1), particularly for mixing, kneading, dispersing and/or similar basic operations in the preparation of solid and/or liquid materials, comprising interchangeable mixing blades (20) arranged radially, preferably in different levels, in recesses (100a, 100b) of said mixing tool holder (1) and at a distance from one another, wherein a quick-release device (2) arranged inside the mixing tool holder (1) is provided, consisting of a plurality of holders (201) that reversibly secure the ends of the mixing blades (20), which project inwards through the recesses (100a, 100b), within the mixing tool holder (1) in a form-fitting or force-fitting manner, said holders being arranged one above the other on an axis or guide bar (200), wherein said holders (201) are clamped by means of the quick-release device (2) in a position that unlocks and releases or locks and reversibly secures the mixing blades (20), characterized in that the casing (10) of the mixing tool holder (1) consists of a plurality of tubular and/or shell-shaped and/or partially tubular casing parts (10a, 10b) arranged concentrically inside one another, wherein the partially tubular casing parts (10b) act as wear-protection shells and the number of recesses (100a, 100b) required to secure the mixing blades (20) are distributed radially over part or over the entire length of the tubular casing parts (10a, 10b). The present invention is particularly advantageous in that it provides a base wear-protection plate (11), which is connected in a form-fitting manner with the underside of the mixing tool holder (1) and is locked or unlocked by a locking means (110) such that it is secured against radial unscrewing and axial removal in a form-fitting and/or force-fitting manner, wherein the locking means (110) is operated synchronously with the locking and unlocking of the mixing blades by the quick-release device (2). |
