And an expansion member 4 which is screwed to the first screw portion 21 of the insertion member 24.

As shown in Fig. 2, the main body 2 is a rod-shaped upper end portion having a fitting portion 22 fitted to the lower end of the small diameter pipe 50, and an inclined portion 25 on the upper outer peripheral surface of the lower side. The first screw portion 21 is formed below the outer circumferential surface adjacent to the inclined portion 25, and an insertion member 24 having an outer diameter narrowed toward the upper portion thereof is integrally formed.

The outer surface of the fitting portion 22 is formed with a plurality of projection jaw 26 to increase the coupling force with the small diameter pipe 100.

Since the first screw part 21 is formed in a left helix, the small diameter pipe 100 may be raised as the main body 2 is rotated clockwise.

A round jaw 23 is formed between the fitting portion 22 and the inclined portion 25 of the main body 2, so that the round jaw 23 is supported at the lower end of the small-diameter pipe 100.

As shown in FIG. 2, the expansion member 4 has a plurality of slits 43 formed in the vertical direction on the upper portion of the cylindrical body, and a plurality of expansion pieces 44 are naturally formed and cut in the vertical direction. A cutout portion 46 is formed, and a second screw portion 42 screwed with the first screw portion 21 is formed below the inner circumferential surface.

As shown in FIG. 3A, the extension piece 44 is formed so as to increase in thickness upward.

The expansion member 4 is cut by the cutout 46, so that the elastic force can be improved, thereby facilitating coupling with the main body 2.

The second screw portion 42 is formed with a spiral in a right direction so as to be opposite to the first screw portion 21.

Looking at the combination and operation of the present invention configured as described above are as follows.

First, the expansion member 4 is inserted into the lower side of the main body 2 to screw the first and second screw portions 21 and 42, but the expansion piece 44 is directed upward so that the inner surface thereof is inclined ( 25).
