ABSTRACT:
A kitchen appliance, having an interchangeable tool attachment, such as a stirrer arm, and an interchangeable container attachment, such as a food chopper. The tool attachment has a base which is secured to the appliance through rotation of a rotatable tension ring assembly, surrounding a power takeoff shaft and a retainer ring, and includes a housing pivotally connected to the base. The container attachment is secured through recesses in its base which engage pins on the retainer ring. A locking bolt is provided on the container attachment which engages the cover thereof, the locking bolt being engageable in a locked position by a slide coupled to a power switch through a blocking rod whenever the power switch is actuated, such that the container attachment cover may not be removed with the appliance in an activated state. An inclined surface on the cover periphery displaces the locking bolt to the locked position when the cover is closed, where a locking finger on the cover engages an opening in the locking bolt.
