能に取付けたもので、このものでは、とじ具のと
じ環の間隔が調節できる。 Moreover, the elastic deformability can be adjusted by the connecting side 24.
This can be done by changing the total length of the connecting sides, but
If only the connecting side 24 is flattened, elastic deformation in the upward direction becomes easier than in a case where the cross section remains round, and conversely, it becomes difficult to deform in the direction perpendicular to the direction of rotation. Therefore, the elastic deformability can be adjusted by the degree of flattening. (See FIG. 4) In the embodiment shown in FIG. 5, the board 4 is slidably attached to the crosspiece 6, and in this embodiment, the interval between the binding rings of the binding tool can be adjusted.
