Abstract:
A food processor comprising:a spindle having a threaded connection part disposed at a lower portion thereof, a rotary joint disposed at an upper portion thereof, and a projection disposed at a top of said rotary joint; a blade holder capable of being combined with said rotary joint of said spindle, and having a pair of blades respectively mounted at both sides thereof, a chamber formed therein, a supporting edge disposed at a top surface thereof, and an engagement edge disposed in said chamber; a positioning member being accommodated in said chamber of said blade holder, and having an engagement part disposed at a lower portion thereof, at least one longer slide slot and at least one shorter slide slot respectively disposed in a peripheral wall thereof, a through hole formed therein, and a plurality of slide grooves disposed in an inner wall surface thereof for corresponding in location to said at least one longer slide slot and said at least one shorter slide slot; an elastic retaining member being accommodated in said through hole of said positioning member, and having a clamp part disposed at a lower portion thereof, a through hole formed therein, and at least one stop block each protruded outwardly from a top thereof for being inserted in and stopped against by said at least one shorter slide slot, said clamp part provided with several split-up slots disposed in a peripheral wall thereof; a flexible member being accommodated in said through hole of said positioning member and placed on said elastic retaining member; a push member being accommodated in said through hole of said positioning member and fitted in said flexible member, said push member having an inclined plane disposed at a bottom thereof, at least one engagement hook and at least one guide block respectively disposed in a peripheral wall thereof, each said engagement hook capable of being inserted in and hooking with each said longer slide slot and sliding in each said slide groove corresponding in location to each said longer slide slot, each said guide block capable of sliding in each said slide groove corresponding in location to each said shorter slide slot; and, whereby only to press down said push member, said at least one engagement hook and said at least one guide block will slide downwards along said slide grooves of said positioning member to compress said flexible member and lower said inclined plane to press against an inner wall surface of said clamp part of said elastic retaining member to force said clamp part to be stretched outwardly so as to release said projection of said spindle, thereby said blade holder, said positioning member, said elastic retaining member, said flexible member and said push member can be disconnected with said spindle mounted on a machine body of said food processor for the convenience of completely cleaning residuary foodstuff out of said blade holder to keep said blade holder in a good sanitary condition ready for the next use.
