The moving rod 901 drives the inclined rod 902 to move downward by cooperating with the first rotating shaft. The inclined rod 902 pushes the vertical rod 903 to move left by cooperating with the second rotating shaft. The vertical rod 903 drives the trapezoidal block 1001 to move left along the moving trajectory provided by the stroke groove 13. The surface of the trapezoidal block 1001 and the surface of the positioning block 7 are squeezed to make the positioning rod 1002 move upward along the moving trajectory provided by the limiting block 12. While the positioning rod 1002 moves upward, the compression spring 1003 is compressed to make the positioning rod 1002 move to the inside of the positioning cavity 8. At this time, the sampling tank 5 can be adjusted. After completion, the moving rod 901 is released, and the positioning rod 1002 is reinserted into the inside of the fixed groove 11 by the rebound force of the compression spring 1003.
