Is commonly used. FIG. 7 is a perspective view of a conventional flare tool. The flare tool is provided with a die 5 and a yoke portion 6, and the die 5 has a plurality of gripping portions 8 composed of two-divided blocks having different diameters. The gripping portions 8 are attached to a die attaching body 7 and a common pressing shaft. It is fastened by 9 and the handle 10. On the other hand, the yoke portion 6 includes a yoke body 11, a yoke 12 and a handle 13.

が発生しやすい。However, since the flare tool is used in combination with the die 5 and the yoke portion 6 which are individual parts, the flare tools are displaced from each other during the flare processing, which results in the yoke 12 at the end of the copper tube. However, there is a problem that it cannot be accurately contacted with each other, resulting in defective construction. Specifically, although the displacement in the Y direction shown in FIG. 7 is small, the displacement in the X direction is likely to occur because it moves relatively freely in the X direction.

供することを目的とする。Further, setting the positioning (insertion dimension of the copper tube end portion from the die) when inserting the copper tube end portion into the grip portion 8 of the die 5 is troublesome. ,
While the handle 10 is being rotated and tightened, the protruding size of the copper pipe is displaced. Further, since the copper tube has relatively weak rigidity and softness, the axis line of the tip portion thereof is easily bent during flare processing, the yoke conical portion 11b does not uniformly press against the opening of the copper tube, and the flare is a complete funnel. It tends to deform without forming a shape.
Then, this invention makes it a subject to solve the problem in the conventional flare tool, and aims at providing the new flare tool for that.
