A security locking system for a kitchen device (13) that is adapted for coupling to a drive unit of the kitchen appliance (13) in order to drive a tool (10) in a rotary manner around a rotation axis (2), wherein the coupling device (1) has a circumferential outer surface (3) comprising at least one receiving region (4) for receiving the tool (10) and wherein the at least one receiving region (4) has a first engagement region (5) and a second engagement region (6) such that the tool (10) can be received along the rotation axis (2) in a manner substantially free of play and irrespective of the direction of rotation (7), wherein the first engagement region (5) has a drive edge (5a) and the second engagement region (6) has a kickback edge (6a), wherein the drive edge (5a) and the kickback edge (6a) run antiparallel to each other, wherein the security locking system comprises one or more blocking regions (21) positioned on the circumferential outer surface (3) of the coupling device (1) directly above, preferably in contact with, the upper edge (22) of the tool (10) in operating position in order to prevent the tool (10) to be disengaged from the coupling device (1) when high forces arise during operation as a result of the processing of hard food ingredients, such as ice, frozen strawberries and carrots. |
