DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the clamp device of the present invention will be described with reference to the drawings. 1 is a front view of an example of the apparatus of the present invention, FIG. 2 is a rear view of the apparatus of FIG. 1, and FIG.
FIG. 4 is a cross-sectional side view of the left half of the drawing for explaining the use state of the device of FIG. 4, FIG. 4 is a plan view of the device of FIG. 3, FIG. 5 is a bottom view of the device of FIG. It is a side view of an example of the use state of.

In FIG. 1, A is a cylindrical main body having the following structure. That is, in the main body A, a bolt head receiving seat 3 having a bolt rod insertion hole at the bottom side of the hole 2 is formed in a cylindrical body 1 having a tapered through hole 2 formed at the center thereof. At the same time, a screw 4 is formed on the outer surface of the lower half side of the cylindrical body 1,
Further, a receiving surface 5 of a cylindrical column is provided on an upper surface of the cylindrical body 1. Here, the cylindrical body 1 is formed with an outer cylindrical portion having a double wall shape continuous with the upper half side from the receiving surface 5 to the outside of the cylindrical body 1, and an uneven surface 6a is formed on the outer surface of this portion. The formed grip portion 6 is formed. In the present invention, the receiving surface 5 may have a separation structure rotatable with respect to the upper surface of the cylindrical body 1. Further, it is assumed that the effective width of the receiving surface 5 for receiving the cylindrical supports having different diameters can be set arbitrarily. Further, the grip portion 6 may not be formed in a double wall shape with respect to the cylindrical body 1, but may be formed in a dirt shape integral with the cylindrical body 1.

On the other hand, the clamp body B has the following configuration. That is, the clamp body B has a substantially horizontal U-shape when viewed from the side of a thick plate body made of a metal material such as aluminum or a synthetic resin material.
The clamp body 7 is formed in a U-shape, and the upper piece 8 of the main body 7 is formed with a screw hole 9 to be screwed with the screw 4 in the cylindrical body A. In addition, the lower end piece 10 of the clamp body 7 has a tip part slightly curved upward for a clamping effect.

Reference numeral 11 denotes a bush inserted into the entrance of the tapered through-hole 2 in the cylindrical main body A for holding the rod-shaped support. In order to hold columns having different diameters, it is desirable to prepare two or more bushings having different inner diameters. However, even when the bush 11 is of a single type, it is sufficient to use a bush 11 having a rib-like projection (not shown) for elastically changing the inner diameter of the bush 11 on its inner surface.

Reference numeral 12 denotes a bolt rod which is inserted from the lower surface of the cylindrical main body A into the seat 3 of the bolt head formed near the bottom of the through hole 2 toward the inlet of the hole 2. The rod 12 has a length such that the threaded portion 12a on the tip side thereof protrudes gently from the upper surface of the cylindrical body 1. Since the bolt rod 12 is a member for supporting the cylindrical pillar, it is not used when the rod pillar is closely fitted and supported in the through hole 2 via the bush 11. It should be noted that the bolt rod 12 in the drawing has a square head with a hole.

In order to support the cylindrical column P1 with the bolt rod 12, the screw portion 12a of the bolt rod 12 is screwed into a screw receiver Pn provided at the lower end of the column P1 and the bolt rod 12 is tightened. The cylindrical support P1 is tightly pressed against the support surface 5 of the support on the upper surface of the cylindrical main body A. This tubular support P

As described above, the rod-shaped or cylindrical pillar P
The cylindrical body A, which holds 1, P2 tightly on the receiving surface 5 of the cylindrical body 1, determines the screwed state of the upper piece 8 of the clamp body B and the screw 4 of the cylindrical body 1, and the clamp body B By rotating the grip portion 6 in a state where the top plate Tb is fitted to the edge of the plate Tb, the top plate Tb is pressed and held between the lower end surface of the cylindrical body 1 and the upper surface of the lower piece 10 of the clamp body B.

In the above-described clamp device, since the clamp body B is still attached to the cylindrical main body A, the cylindrical body 1
Screw 4 in the lower part of the screw and screw hole 9 in the upper piece 8 of the clamp body 7
Can be seen from the outside. In the illustrated example of the present invention, the cover 13 is used to cover this portion from the outside, so
I did it.

That is, in the illustrated example, the cover body 13 has a circular upper opening 13a at the upper part thereof into which the lower part of the cylindrical body 1 can be loosely inserted, and the upper piece 8 of the clamp body 7 is loosely fitted to the side surface. It is formed of a bottomed tubular body provided with a side opening 13b. 13c is the bottom of the cover 13. Thus, the clamp device of the present invention can be designed to have a smart and good-looking shape by covering the joint between the cylindrical body 1 and the clamp body 7 with the cover 13 from the outer surface thereof. In this sense, the cover 13
Can be formed into an arbitrary shape integrally with or separate from the upper piece 8 of the clamp body 7 and supported by the upper piece 8.

The above-described clamping device of the present invention is used in an embodiment shown in FIG. 6 as an example. That is, the cylindrical main body A
