An automatic pushing type complementary food device comprising a clamping body, an elastic member and a colander, wherein an inner side of the clamping body is connected to one end of the elastic member in a clamped manner, an outer side of the clamping body is connected to the colander in a clamped manner, the other end of the elastic member extends into the colander, a complementary food cavity is provided in the colander, and overflow holes are provided in an outer wall of the colander, wherein an air hole penetrating the clamping body is provided on the clamping body, and a cavity communicating with the air hole is provided on the elastic member, wherein, one end of the elastic member provided with the cavity is a clamping end, the other end of the elastic member is a free end, a surface of an outer sidewall of the free end of the elastic member is a corrugated surface, and a top end of the corrugated surface is adhered to an inner wall of the colander, a first clamping protrusion is provided at the outer side of the clamping body, and a second clamping protrusion is provided at the inner side of the clamping body; the first clamping protrusion is located above the second clamping protrusion, and the cross section of the first clamping protrusion is a right-angled trapezoid; the cross section of the second clamping protrusion is a right-angled trapezoid. (Claim 7) characterized in that, the colander includes a colander main body and a connecting piece, the connecting piece is in clamping fit with the clamping body, the colander main body is movably connected or fixedly connected with the connecting piece; the colander main body includes a mating section and a feeding end; the mating section is a rotary body for sliding mate with the elastic member; the feeding end is a shuttle body with an oblong cross section, and a sidewall is provided with the overflow holes for overflowing complementary food. (claim 10) oblong major axis diameter of the largest cross section of the feeding end is greater than diameter of cross section of the mating section; and the sidewall of the feeding end is arranged with a plurality of annular recesses which are in conformity with arc shape of baby teeth, surface of the annular recesses is arc-shaped, and a plurality of the overflow holes are located in the annular recesses, and distributed in one large and one small array along the annular recesses on upper and lower surfaces of the shuttle body. Claim 2. An automatic pushing type complementary food device comprising a clamping body, an elastic member and a colander, wherein an inner side of the clamping body is connected to one end of the elastic member in a clamped manner, an outer side of the clamping body is connected to the colander in a clamped manner, the other end of the elastic member extends into the colander, a complementary food cavity is provided in the colander, and overflow holes are provided in an outer wall of the colander, an air hole penetrating the clamping body is provided on the clamping body, and a cavity communicating with the air hole is provided on the elastic member, one end of the elastic member provided with the cavity is a clamping end, the other end of the elastic member is a free end, a surface of an outer sidewall of the free end of the elastic member is a corrugated surface, and a top end of the corrugated surface is adhered to an inner wall of the colander, characterized in that, the colander includes a colander main body and a connecting piece, the connecting piece is in clamping fit with the clamping body, the colander main body is movably connected or fixedly connected with the connecting piece; the colander main body includes a mating section and a feeding end; the mating section is a rotary body for sliding mate with the elastic member; the feeding end is a shuttle body with an oblong cross section, and a sidewall is provided with the overflow holes for overflowing complementary food, oblong major axis diameter of the largest cross section of the feeding end is smaller than diameter of cross section of the mating section; a plurality of the overflow holes are distributed in one large and one small array on upper and lower surfaces of the shuttle body, and arc of arc line formed by connecting central points of each row of the overflow holes has the same arc as arc shape of baby teeth. Claim 1. An automatic pushing type complementary food device comprising a clamping body, an elastic member and a colander, wherein an inner side of the clamping body is connected to one end of the elastic member in a clamped manner, an outer side of the clamping body is connected to the colander in a clamped manner, the other end of the elastic member extends into the colander, a complementary food cavity is provided in the colander, and overflow holes are provided in an outer wall of the colander, an air hole penetrating the clamping body is provided on the clamping body, and a cavity communicating with the air hole is provided on the elastic member, one end of the elastic member provided with the cavity is a clamping end, the other end of the elastic member is a free end, a surface of an outer sidewall of the free end of the elastic member is a corrugated surface, and a top end of the corrugated surface is adhered to an inner wall of the colander, Claim 7. characterized in that, the colander includes a colander main body and a connecting piece, the connecting piece is in clamping fit with the clamping body, the colander main body is movably connected or fixedly connected with the connecting piece; the colander main body includes a mating section and a feeding end; the mating section is a rotary body for sliding mate with the elastic member; the feeding end is a shuttle body with an oblong cross section, and a sidewall is provided with the overflow holes for overflowing complementary food.

Claims 1-2 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims of U.S. Patent No. 12,263,138. Although the claims at issue are not identical, they are not patentably distinct from each other because: the claims 1, 7 and 10 of U.S. Patent No. 12,263,138 encompasses all claimed limitation in claim 1, and the claims 1, 7 and 11 of U.S. Patent No. 12,263,138 encompasses all claimed limitation in claim 2, as set forth supra. Also, it would have been obvious to one of ordinary skill in the art to eliminate limitations to broaden the claim and/or when they are not needed. Claims 1-2 would be allowable if rewritten to overcome the objection above and filing a terminal disclaimer to overcome the double patenting rejection.
