Subsequently, the pivoting member 22 is rotated to bring the closing portion 27 of the pivoting member 22 closer to the opening-shaped fitting wheel 24 of the fitting wheel seat body 21. This is as shown in FIG. Further, when the pivot member 22 is pushed to the rearmost (inward), the dovetail-shaped projection 271 of the pivot member 22 fits into the dovetail groove 242 of the fitting wheel seat body 21 and the closing portion 2
7 and the open ferrule 24 combine to form one complete ferrule. This is as shown in FIG. FIG.
As shown in (2), the fitting ring is further provided outside the holding piece 11 positioned on the upright pipe 10 and the fitting ring is fixed, so that the rod 40 connected to the fitting ring sheet 20 is formed.
Alternatively, the net shelf 30 is positioned on the pipe rack 1. The rod 40 or the net shelf 3 provided with the above-mentioned fitting wheel sheet 20
When it is desired to remove 0 from the pipe rack 1, it can be smoothly removed by performing the above operation in the reverse order of the assembling process. Therefore, the present invention attaches the net shelf 30,
Convenient for removal and quick operation.

The holding piece 1 in which a complete fitting ring formed by coupling the opening-like fitting ring 24 of the fitting ring seat body 21 and the closing portion 27 of the pivot member 22 of the present invention is attached to the upright pipe 10.
When restraining and suppressing the number 1, the fitting wheel can keep the surrounding shape by the engagement of the dovetail-shaped protrusion 271 and the dovetail groove 242.

The inner diameter of the fitting ring formed by joining the opening fitting ring 24 and the closing portion 27 gradually increases upward or downward, and is combined with the outer diameter of the holding piece 11 to achieve the effect of tightening the slope. .

When assembling the present invention to the pipe rack 1, as shown in FIG. 4, after approaching the upright pipe 10 from the side, the upright pipe 10 is opened from the opening of the opening fitting ring 24. The fitting ring 24 is advanced into the fitting ring 24, and the closing portion 27 and the opening-like fitting ring 24 are closed to form a complete fitting ring. The fitting ring is further moved downward to cover the outside of the holding piece 11 to complete the assembly. .

The fitting wheel seat body 21 has one rod 4.
In addition to being able to be installed at both ends of “0”, it can be installed at two corners or four corners of the net shelf 30 as shown in FIGS.

The present invention only needs to achieve the following requirements in manufacturing. 1. Opening 2 of opening fitting wheel 24 of fitting wheel seat body 21
The width of 41 is larger than the outer diameter of the upright pipe 10, and a groove 242 is provided at the front edge of the open fitting ring 24. 2. By closing the closing portion 27 of the pivot member 22 and the opening-shaped fitting ring 24 to form a complete fitting ring,
