Further, at a position corresponding to the axial groove 23 of the rod-shaped body 18, two balls 26, which enter the groove 23 and stop the rotation of the cylindrical body 19, are provided diametrically opposite to each other. A semi-circular curved leaf spring covers the ball from above, holds the ball there, and allows the cylindrical body 19 to rotate while clicking or detenting with respect to the rod body 18. It is pressing inward. The end of the tubular body 19 is formed as a knob 28 so that it can be easily rotated. For the post 5 in which the tubular body 19 is connected to the rod-shaped body 18 as described above, the pair of spiral grooves 24, 24 of the tubular body 19 and the rod-shaped body are provided on the protruding portion 7 of the support disk 6. A pin 30 is fitted through a diametrical hole located at the intersection of 18 with the slit 20.

Since the post 5 has the above-described structure and the support disk 6 is connected by the pin 30 at the protrusion 7, the height of the support disk can be changed by rotating the tubular body. This operation will be described with reference to FIGS. For convenience of explanation, the support disk 6 is brought close to the top 8 from the state where the support disk 6 is closest to the bottom surface 4 and the length of the fastener that can be accommodated is the maximum as shown in FIGS. 1 and 2. And shall be modified to accommodate shorter fasteners. FIG. 5 shows a state in which the support disk 6 is closest to the bottom surface 4, and in this state, the pin 30 of the protrusion 7 of the support disk 6 is formed at a position closest to the bottom surface 4. It is located at the intersection of the spiral groove 24 of the strip 19 and the slit 20 of the rod 18. Incidentally, the pin 30 in FIG. 4 is also in the same position as in FIG. Then, the tubular body 19 is rotated 90 degrees with the knob 28 as indicated by an arrow 31. Accordingly, the hole located at the intersection of the spiral groove 24 and the slit 20 moves to the side of the top 8 (right side of FIGS. 5 to 7) together with the intersection, and the pin 30 also moves accordingly. . The protrusion 7 is moved by the movement of the pin 30, and the support disk 6 is moved to the side of the top portion 8 to change the height with respect to the top portion. When the tubular body 19 is rotated, each ball 26 of the tubular body 19 moves to the next axial groove 23 90 degrees away from one axial groove 23 of the rod 18 and is held at this position. . As shown in FIG. 4, the spiral groove 24 is also formed so that the pin 30 is held not only at its both ends but also at the intermediate position 32. Therefore, if it is desired to further change the height of the support disk 6, the knob 28 may be rotated as indicated by the arrow 33 in FIG. In this way, the height of the support disk can be easily changed by rotating the tubular body 19.
