Abstract

The present utility model provides a hand-pulling food cutter/mixer, which comprises a container, a lid on the container and a processing implement in the container, and is characterized in that a hand-pulling driving mechanism is fixed into the lid, and comprises a torque-receiving device, a driving device and a torsional spring group one end of which is fixed to said upper lid and the other end of which is fixed to the driving device having a cord with a pull handle and a hollow drive gear the inner side of which has supporting teeth, the lower part of the torque-receiving device is a upright axis and the upper part of the torque-receiving device is a cob from the circumference of which at least two elastic arms, the end of each of which has a protruding end, extends symmetrically and oppositely, the upper part of the torque-receiving device is positioned in the hollow part of the drive gear, each of the protruding ends of the elastic arms is positioned between two of said supporting teeth, the upper part of the processing implement is positioned around the upright axis of the torque-receiving device. The present utility model has a low production cost, saves energy, and is safe and convenient to use.

Claims

1. A hand-pulling food cutter/mixer, comprising a container, a lid on said container and a processing implement in said container, characterized in that said lid comprises an upper lid the underside surface of which has a downward shaft, and a hand-pulling driving mechanism fixed to said upper lid and positioned around said shaft, and the lower part of said hand-pulling driving mechanism has a protruding upright axis around which the processing implement is positioned.

2. A hand-pulling food cutter/mixer according to claim 1, characterized in that said hand-pulling driving mechanism comprises a torsional spring group one end of which is fixed to said upper lid, a driving device, to which the other end of said torsional spring group is fixed, comprising a hand-pulling force-applying piece and a drive gear, a torque-receiving device the upper part of which is a force-receiving part around which the drive gear is positioned and the lower part of which is said upright axis, and a supporting cover through which said upright axis extends.

3. A hand-pulling food cutter/mixer according to claim 2, characterized in that said inner side of said drive gear has supporting teeth, and said force-receiving part comprises at least two elastic arms, the end of each of which has a protruding end positioned between two of said supporting teeth, extending symmetrically and oppositely from the circumference of a cob.

4. A hand-pulling food cutter/mixer according to claim 2, characterized in that said hand-pulling force-applying piece has an upper disk plate and a lower disk plate both of which have a same short axis coiled by a cord the outer end of which has a pull handle, and the side of said supporting cover has a slot through which said cord passes, and the surface of the upper lid has a small hole through which the cord extends and outside of which said pull handle is positioned.

5. A hand-pulling food cutter/mixer according to claim 2, characterized in that said torsional spring group is composed of several layers of coaxial spring loops formed by coiling a spring from inside to outside along a certain direction, and the two inside and outside ends of said the torsional spring group are curved to form opposite inside and outside hooks, and the inner surface of said upper lid has an annular ring having an opening caught by said outside hook, the upper part of said driving device has a small column caught by said inside hook.

6. A hand-pulling food cutter/mixer according to claim 4, characterized in that said torsional spring group is composed of several layers of coaxial spring loops formed by coiling a spring from inside to outside along a certain direction, and the two inside and outside ends of said the torsional spring group are curved to form opposite inside and outside hooks, and the inner surface of said upper lid has an annular ring having an opening caught by said outside hook, the upper part of said driving device has a small column caught by said inside hook.

7. A hand-pulling food cutter/mixer according to claim 1, characterized in that the underside surface of said upper lid has several column apertures, and said hand-pulling driving mechanism has column holes corresponding to said column apertures, bolts are screwed into said column apertures and said column holes to secure said supporting cover to said upper lid.

8. A hand-pulling food cutter/mixer according to claim 1, characterized in that the bottom center within said container has a small protuberance, and the lower part of said processing implement is positioned around said protuberance.

9. A hand-pulling food cutter/mixer according to claim 3, characterized in that said hand-pulling force-applying piece has an upper disk plate and a lower disk plate both of which have a same short axis coiled by a cord the outer end of which has a pull handle, and the side of said supporting cover has a slot through which said cord passes, and the surface of the upper lid has a small hole through which the cord extends and outside of which said pull handle is positioned.

10. A hand-pulling food cutter/mixer according to claim 3, characterized in that said torsional spring group is composed of several layers of coaxial spring loops formed by coiling a spring from inside to outside along a certain direction, and the two inside and outside ends of said the torsional spring group are curved to form opposite inside and outside hooks, and the inner surface of said upper lid has an annular ring having an opening caught by said outside hook, the upper part of said driving device has a small column caught by said inside hook.

11. A hand-pulling food cutter/mixer according to claim 9, characterized in that said torsional spring group is composed of several layers of coaxial spring loops formed by coiling a spring from inside to outside along a certain direction, and the two inside and outside ends of said the torsional spring group are curved to form opposite inside and outside hooks, and the inner surface of said upper lid has an annular ring having an opening caught by said outside hook, the upper part of said driving device has a small column caught by said inside hook.
