When water body sampling is required, at first, the magnetic force of the first magnet 11 and the second magnet 12 between the movable block 10 and the first housing 1 is overcome by manpower to adjust the movable block 10 to the required position, that is, the opening of the water inlet pipe 9 Adjust the end to the required position, repeat the above operations until the opening ends of the two water inlet pipes 9 are adjusted to the required position, that is, the water body of various depths can be sampled at the same time in a single time, which improves the efficiency of the sampling work. Effect;

The adjustment member includes a connecting groove 15 opened inside the movable block 10 near the water inlet pipe 9, a first connecting plate 16 fixedly connected to the inner side of the connecting groove 15 near the middle, and a first connecting plate 16 fixedly connected to the top surface of the first connecting plate 16 near the middle. The second housing 18 is rotatably connected to the rotating rod 19 on the bottom surface of the second housing 18, the second extruding plate 20 is screwed to the side of the rotating rod 19, and the second extruding plate 20 is screwed to the bottom of the second housing 18 and extends to close to the first The second connecting plate 17 on the lower side of the connecting plate 16, the connecting hole 3 on the side of the first connecting plate 16 and the second connecting plate 17, and the connecting hole 3 on the side of the second housing 18 close to the lower part of the second extruding plate 20.
