本考案は締付固定具であるボルトナツトのナツ

が大変面倒でもあつた。 When tightening and fixing a supported body with a bolt/nut, if the bolt is long and the supported body needs to be tightened and fixed in an arbitrary position as shown in Figure 1, it is necessary to tighten and fix the supported body in an arbitrary position as shown in Figure 1. Therefore, the supported object is positioned. At this time, if the supported object is to be fixed at a lower position in the drawing, the nut must be moved from the upper bolt tip to the position where the supported object is to be fixed. must be rotated continuously,
Not only is the operation complicated, but it also significantly reduces work efficiency. The same applies if it is necessary to remove the nut. Furthermore, if any part of the bolt is crushed or rusted, it is very troublesome to move the nut to the desired position.

た。 Conventionally, in cases such as the above,
There are techniques described in Publications No. 16422, No. 48-30516, No. 53-12376, and the like. In the former two techniques, the nut is pivoted on one side so that it can be opened and closed, and the nut is provided with a handle for tightening, so both are difficult to mold and difficult to manufacture. The cost is high, and since the handle is larger than the width of the nut, this handle becomes a nuisance and cannot be tightened in a narrow place. On the other hand, in the latter technique, a cap having an inner diameter slightly larger than the outer diameter of the non-circular fastening fitting (represented by a hexagonal nut in the illustrated embodiment) is prepared for each nut. It is not easy to manufacture the cap, and since it needs to be rotated together with the hexagonal nut when tightening, a huge force is applied to the cap, so it is necessary to make the cap sturdy. This has resulted in a drawback of high manufacturing costs.

る。 Since the present invention is constructed as described above, when using this nut body 6, first insert the center part O1 of the insertion hole 7 of the nut main body 6 and the center part of the large diameter part 9a of the female screw forming member 10. Insert the nut body 6 from the tip 4 of the long bolt 1 to the supported body 2 to be tightened and fixed while aligning the bolts with O2 . In this case, since the diameter D 2 of the insertion hole 7 of the nut body 6 is larger than the outermost diameter D 1 of the bolt 1, the nut body 6 can be inserted to a desired position. Then, the female thread forming member 10 is moved in the direction of the arrow in the drawing by hitting, and the center O 3 of the small diameter portion 9b of the female thread forming member 10 is aligned with the center O 1 of the insertion hole 7. If you do so, the valley part 1b of bolt 1
The small diameter portion 9b is fitted together to form a female screw portion 9'. Therefore, the supported body 2 can be tightened and fixed by only slightly rotating the nut body 6.
To release the nut main body 6, the operation can be performed in the opposite direction.If the female thread forming member 10 is moved by hitting it in the direction opposite to the direction of the arrow, the female thread portion 9' will be released. The nut body 6 can be easily removed from the bolt 1 together with the female thread forming member 10.
