It is printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. It uses the hexagon ^ a that conforms to the shape of the hexagon nut 26 to form a rotation restricting part that restricts the rotation of the hexagon nut 26. It is possible to rotate the nut 26 at the corner of the hole 25 with the whole part of the hole 25. Therefore, when the threaded rod 28 is rotated, the soil limiting six female 26 can be stably fixed, and it is easy to perform screw threading. Rotating operation of stem 8. Figs. 4 and 5 show the second embodiment of the present invention. Compared with the first embodiment 2-10, there are the following differences. That is, in the example of Shishiyuan and the lower portion 21b, the simple limiting wall 31 of the substitutional cavity portion 25 of the rotation restricting portion ^ that restricts the rotation of the hexagonal nut 26 is constituted. Hexagonal nut% = production, the outer side of 26 can abut the restricting wall 31, and it has a structure that restricts the rotation of the hex nut 26. Even with this structure, basically the same effect as that of the first embodiment can be obtained. The present invention is not limited to the above-mentioned embodiments, and can be expanded to the following cases. The present invention is not limited to a mounting device for mounting a lighting fixture such as a work lamp, a desk lamp, and the like, and can also be applied to a tight device for clamping an object. As for the nut part, not only a hex nut but also a wing nut can be used. [Effects of the Invention] From the above description, it is clear that in the present invention, the adjustment of the clamping width is 20 -9- $. The paper size applies the Chinese National Standard (CNS) A4 specification (210 x 297 mm). When the consumer cooperative printed five instructions, the nut was rotated with the fingers in a freely rotating state, and the nut part was moved relative to the threaded rod, so that the nut part could be moved quickly, so the clamping range could be adjusted quickly. In this structure, in addition to the soil body and the threaded rod, it is only necessary to have a hexagonal nut, compared with a conventional clamping device that must have a cylindrical member and a fixing screw that holds two cylindrical members. Not only the number of W parts, but also the structure is simplified. In addition, it is necessary to form an internal thread in the guide of the main body, and the hexagon nut is a commercially available product, and it is also manufactured, which can further reduce the cost. Must be special 10 [Brief description of the drawings] Fig. 1 is a sectional side view showing the i-th embodiment of the present invention in a six-free state. ^ Nut shoulder • Figure 2 shows the air surface when the hexagon nut is accommodated in the cavity of the main body. 15 Figure 3 is a perspective view of important components.
