Equipped with.

Next, the fixed expansion and contraction control device 4 will be described. In other words, the fixed expansion and contraction control device 4 is inserted into the base column 6a so that the support column 6b having a smaller diameter than the base column 6a can be lifted, and the support column at any position. (6b) was fixed.

The fixed expansion and contraction adjusting device 4 includes a first stopper member 10 mounted on the upper end side of the base support 6a and a support support 6b on the outside of the first stopper member 10. It is provided with the 2nd stopper member 11 comprised so that rotational movement is possible, and it is comprised by processing so that thickness may become thick or thin for a while, and the outer periphery part (after-mentioned) of the mounting part of the said 1st stopper member 10 turns around. .

The second stopper member 11 is rotated to be in contact with the outer peripheral portion of the mounting portion of the first stopper member 10 so as to deform the mounting portion in the radial direction, and thus by the mounting portion of the first stopper member 10. The supporting column 6b is pressurized and held or loosened by a reverse rotational operation to allow the lifting and lowering.

The first stopper member 10 has a coupling pipe shape formed of synthetic resin, and the base holder mounting portion 10a is formed by holding the upper end side of the base holder 6a inside and held by the holding member. ) And a support holder insertion portion 10b through which the support holder 6b is inserted.

When the upper end of the base holder 6a is inserted into the base holder mounting portion 10a, the guide holder for maintaining the upper end of the base holder 6a so as not to fall out and guiding the support holder 6b ( 12) is projected.

Moreover, the said support holding penetration part 10b is provided with the slit S of a perpendicular direction in all directions, and can bend and deform in radial direction by this. The outer circumferential portion of the support holder insertion portion 10b is configured to be thickened alternately in a range of 180 ° with one slit S therebetween in the circumferential direction.

On the other hand, the second stopper member 11 is in the form of a rotary motion operation pipe having an inner diameter that can be fitted to the first stopper member 10 from the outside, and the upper half of the outer circumference portion makes the rotary motion operation easier. For this reason, it has a swelling shape, and anti-slip ribs R are provided at equal intervals.

The second stopper member 11 has a dimension whose inner diameter is substantially equal to the outer diameter of the base holding portion 10a.

Further, the upper half of the inner circumferential portion of the second stopper member 11 fits the step portion of the boundary between the base circumference mounting portion 10a and the support circumference insertion through portion 10b of the first stopper member 10.

The support column 6b can be pressurized by the inner circumferential wall of the insertion through part 10b, and the support column 6b can be maintained so that it does not vibrate abnormally in its place. When the second stopper member 11 is rotated in the tightening direction, the relative positional relationship between the outer circumferential surface of the support holding insert penetrating portion 10 'and the inner circumferential surface of the pressing projection 13 is gradually changed. Pressurized on the inner circumference Holding insertion portion (10b) is deformed inward. 10-12 show the state which does not deform for convenience. Therefore, in the place where the support column insertion penetrating portion 10 'is originally deformed inward, the support column insertion penetrating portion 10' and the pressing projection 13 are shown overlapped, but in reality, this overlap (overlap) portion is shown. The supporting column insertion penetrating portion 10 'is deformed inwardly so that the support column disappears. In this way, the support column insertion penetrating portion 10 'is pressed by the pressing protrusion 13 and deformed inward, thereby supporting the support column 6b.

In this way, by pressing the support column 6b on the inner wall of the support column insertion through portion 10b in the first stopper member 10 and holding the support column 6b so as not to vibrate in place, As described above, there is no fear that the small diameter pipe material that fits the shaft portion of the knob bolt is locally deformed or damaged, such as a tightening method by the knob bolt.

In addition, the problem that abnormal vibration on the side of the pipe with a small diameter remains, such as a system fitted into the dedicated attachment hole, can be solved.
