ABSTRACT:
Snap-on fastener apparatus for removably holding tools on a drive shaft turned by the motor of a household electrical appliance, particularly shown as a food processor with multiple uses, in which interchangeable rotary tools of various shapes and types are employed as a function of the different food preparation tasks to be performed. A protective sheath surrounds the drive shaft and a sheath portion of the tool hub engages upon the sheath of the drive shaft. Fastener apparatus enables the user to affix the desired tool upon the drive shaft sheath in a snap-on manner for removably holding the tool against axial displacement relative to the drive shaft and enables the rapid and convenient installation or removal of the tools without the use of accessories. As the tool is being introduced onto the drive shaft, a flange spreads a plurality of elastic retainer clips which then snap back to reclose over the flange when the tool is fully installed for retaining it in position.
