The first fixing member 11 and the second fixing member 12 are pre-fixed by inserting the positioning column 500 into the positioning hole, and then fixed by screwing the first threaded cover 2, so as to avoid dislocation between the first fixing member 11 and the second fixing member 12, which makes it difficult to screw the first threaded cover 2, and makes the splicing more convenient and fast.

[0044] Preferably, the first fixing member 11 and the second fixing member 12 are both hollow shell structures, which can be formed by blow molding, and have simple structure, low cost, convenient production and processing, and buffering protection effect, so as to avoid damage of the sampling bottle 2000 caused by collision.

[0045] Further, the sampling bottle fixing device 1000 further comprises a counterweight (not shown, the same below) filled in the first fixing member 11 and the second fixing member 12.
