Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

The overall construction according to the preferred embodiment of the present invention will be schematically described with reference to the attached drawings. It can be seen that the components are constituted by the components of the catching pot 1, the drawstring 10 and the expansion joint 20, 20a.

Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

1 to 4, a plurality of support bars 4 are connected between upper and lower rings 2 and 3, and a main body 5 having a plurality of support bars 4 connected to the main body 1, 5 has an inlet port 7 formed at the center of the upper portion of the mesh network 6 and an inlet port 8 formed at the side of the mesh network 6 .

The present invention is characterized in that a drawstring 10 that serves to tighten the inlet 7 is connected to an expansion joint 20 or 20a in which a hook 22 is integrally formed to insert the drawstring 10 into an expansion joint The hook 22 is hooked on the lower ring 3 as shown in FIGS. 3 to 4 so as to maintain the locked state of the inlet / outlet 7 of the catcher 1 after the hook 22 is tightened by the elastic force of the hook 20 .

As shown in Fig. 1, the drawstring 10 is integrally formed along the periphery of the inlet / outlet 7 formed on the mesh 6 of the catching pot 1, (20) and (20a).
