  However, since the eaves rod cutting jig 51 described in the above publication employs a method of fitting the eaves rod cutting jig 51 to the eaves rod 52 at the time of cutting, the eaves rod cutting jig 51 itself is elastic to some extent. In addition, after holding one of the ears 57 of the eaves hook 52 with the ear holding part 63 of the eaves hook cutting jig 51, an elastic clip tool 66 prepared separately is used. It was necessary to firmly attach the eaves hook 52 and the eaves hook cutting jig 51 by using both of them. That is, a special auxiliary tool for firmly attaching the eaves hook 52 and the eaves hook cutting jig 51 is necessary.

  On the other hand, when such a special auxiliary tool is not used, it is necessary to use a material that can securely and firmly hold the ears 57 and 58 of the eaves rod 52 as a material constituting the eaves rod cutting jig 51. However, if such a material is used, it is difficult to use a fitting method because the eaves-cutting jig 51 is attached to a predetermined position of the eaves-cutting 52. For example, a method of sliding 51 to be positioned at a predetermined position is used. In the method of sliding and attaching the eaves-cutting jig 51, there is a risk of damaging the surface of the eaves-cutting 52 when the eaves-cutting jig 51 is removed after cutting. Further, depending on the dimensional variation of the eaves bowl main body 56, when the eaves bowl cutting jig 51 is attached to the eaves bowl 52, the attached state is loose and there is a problem that the eaves bowl cutting jig 51 moves during cutting. .

  Therefore, the present invention is made from the background as described above, and can be easily attached to and detached from the eaves without using a special auxiliary tool for attachment to the eaves. Moreover, it is an object of the present invention to provide an eaves cutting tool that can absorb even if there is a variation in the eaves dimensions and can be securely attached to perform the cutting operation.

  In order to solve the above-mentioned problem, the eaves-cutting jig according to the present invention is used first for cutting an eaves having ears at both upper and lower ends, and includes a bottom wall portion and a front wall portion.

On the upper side of the wall portion, the front wall portion main body inner side and the rear wall portion main body inner side branch, the tip extends horizontally inward, and the ear portion pressing protrusion is provided along the jig body width direction below the tip. Each of the ear pressing pieces has a finger pressing piece having a finger pressing flat portion at the tip of each of the ear pressing pieces, and the ear pressing pieces and the fingers on the front wall side and the rear wall side. Each of the push pieces is attached with elasticity using a branch portion between the front wall main body and the rear wall main body as a fulcrum.

  According to a second aspect of the present invention, the finger pressing flat portion of the finger pressing piece is an inclined surface.

  According to the invention of claim 1 of the present application, the front end of the jig main body is branched from the front wall portion and the rear wall portion from the inner side of the front wall portion and the inner side of the rear wall portion. The ear pressing ridges have ear pressing pieces provided along the width direction of the jig body, and finger pressing pieces having finger pressing flat portions are respectively provided at the tips of the ear pressing pieces. Because the ear pressing piece and finger pressing piece on the front wall side and the rear wall side are attached with elasticity by using the branch part of the front wall main body and the rear wall main body as a fulcrum, respectively When attaching the cutting jig to the eaves, it can be easily fitted by the elasticity of the ear pressing piece and the finger pressing piece, and the mounting is performed without loosening by absorbing the variation in eaves dimension. The cutting work can be performed without moving the eaves-cutting jig. The flat portion for pressing it is possible to easily remove the eaves gutter cutting jig by pressing with a finger.
