The present invention includes a branch pipe, a watertight packing, a saddle, a fastening nut, an inner washer, and a plurality of bolts to solve the problems of the background art described above.

That is, the first configuration is generally cylindrical from the top to the bottom, a longitudinal groove corresponding to the screw portion and the protrusion on the saddle inner side from the upper end to the lower end from the upper circumferential surface at a predetermined distance from the upper end to the predetermined distance is formed, A branch pipe having a plurality of bolt holes formed therein and a branch corresponding to the inner washer protruding pipe longitudinal groove at the lower side of the protruding frame and integrally forming an upper part of the tubular packing at the lower lower side; While having a tubular contact portion, the upper portion is integral with the lower side of the branch pipe, and the lower portion is a bullet shape having a curved lower surface, and forms a protrusion corresponding to the inner washer protruding tube longitudinal groove at a predetermined distance from the upper end of the inner circumferential surface, The curved surface is projected to the lower side of the protrusion is integral with the upper side of the bullet-shaped inward, and the C-shaped groove is formed in the lower portion of the tubular outer circumference along the bullet-shaped lower surface and the inner surface curved surface, and the peripheral edge of the groove A curved wing piece is integrally formed between the bullet-outward upper periphery, and the yo-hom is inserted with an O-ring, which is a soft packing material, and the tubular inner surface is in contact with the inner washer projecting tube, and the tubular outer circumferential surface and the O-ring A part is in contact with the inside of the branch hole and the periphery of the end, and the part of the O-ring and the curved wing piece contact the pipe inner surface by the curved wing piece of the inner washer. Watertight means are comprised of packing; A protrusion corresponding to the branch pipe outer circumferential longitudinal groove is formed in the protruding pipe which is picked up and wrapped up in the upper threaded portion of the branch pipe and moves up and down, and is a curved wing piece which is integral with the lower side of the protruding pipe and lies on the outer surface of the branch hole peripheral pipe. Birds whose trachea is correctly supported in position with the branch hole; A fastening means that is tightened by the branch pipe threaded portion and comprises a nut for pressing the top surface of the saddle protruding pipe; The inner surface of the pipe having a larger outer diameter than the branched hole is integrally formed with a protruding tube which is a curved curved surface so that the upper periphery of the outer surface is slid into the inner surface of the tubular packing. Longitudinal grooves corresponding to the protrusion and the inner surface of the protrusion and the branch pipe are formed, and the female thread portion corresponding to the plurality of bolt holes and the inner surface of the branch pipe in the protruding pipe is formed up and down, and the protruding pipe and the curved wing piece are divided up and down and hinged. Inner washer connecting the curved wing piece cross section into one; And a plurality of bolts corresponding to the inner washer protruding pipe female screw to tighten the branch pipe and the inner washer so that the bullet outward upper peripheral curved wing piece and the O-ring outward upper part are in contact with the inner surface of the inner washer curved wing piece. Configured assembly means; And the like. At this time, the tubular packing and O-ring may be integrated, and in order to integrate the lower part of the branch pipe and the upper packing, a double injection or a groove groove 211 is formed at the lower periphery of the branch pipe and the branch pipe is formed on the packing upper part. A projection frame corresponding to the lower groove of the lower periphery is formed, and the grooves surrounding the inner and outer edges of the branch pipe may be a packing formed downward from the upper surface of the packing. In addition, a vertical protrusion is formed on the inner surface of the packing and a protruding curved surface, and a vertical protrusion is formed on the inner surface of the branch pipe at the same position as the vertical packing on the inner side of the branch washer.
