Slide holes 15 are provided on both sides of the square tube 14. Insert rods 16 are slidably connected in the two slide holes 15. Through the provided adjustment component, the square frame 5 can be adjusted to different positions, thereby adjusting the float 12 to different positions, thereby making the device enter the water at different depths, collecting water bodies of different depths, and obtaining different For water samples of the same depth, a limiting plate 17 is welded on the circumferential outer wall of the rod 16, and the limiting plate 17 contacts the inner wall of one side of the square tube 14.
