[0031] AsFigures 1-5 As shown in the figure, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a clamping block 16 is fixedly connected to the top of the connecting block 15, and limiting blocks 17 are fixedly connected to both sides of the connecting block 15. A transverse groove 18 is formed inside the U-shaped frame 13, and the outer wall of the limiting block 17 is slidably connected to the inside of the transverse groove 18.

[0033] Next, the working principle of the sampling device for the analytical instrument will be specifically described.

[0034] As Figures 1-5 shown, when sampling the water surface is required, the user pulls the pulling rope 9, and the pulling rope 9 will drive the water blocking plate 7 to move upward inside the water storage pipe 6 through the spring, blocking the inside of the water storage pipe 6. When the top of the water storage pipe 6 contacts the water, the user loosens the pulling rope 9, and the pulling rope 9 will drive the water blocking plate 7 to descend inside the water storage pipe 6 through the spring, and the water will flow into the inside of the connecting pipe. Then the user pulls the pulling rope 9 again, and the pulling rope 9 will drive the water blocking plate 7 to move upward inside the water storage pipe 6 through the spring, and thus the shallow water surface can be sampled.

[0035] When it is necessary to sample water at a deeper depth, the user selects the corresponding counterweight 14 according to the descending depth, and then installs the counterweight 14 and the fixing plate 13 on the bottom of the support plate 12 through bolts 16. Then the user pulls the pull rope 9, and the pull rope 9 will drive the water blocking plate 7 to move upward inside the water storage pipe 6 through the spring to block the inside of the water storage pipe 6. The user judges the descending depth by observing the floating ball 4. When the water storage pipe 6 descends to the required position, the user slowly releases the pull rope 9, and the pull rope 9 will drive the water blocking plate 7 to contract inside the water storage pipe 6 through the spring, and water will flow into the inside of the connecting pipe. Then the user pulls the pull rope 9 again, and the pull rope 9 will drive the water blocking plate 7 to move upward inside the water storage pipe 6 through the spring to block the inside of the water storage pipe 6, so as to sample water at different depths.

[0036] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art.
