At the same time, the rotating rod 65 pushes the push rod 66 to move forward, and the push rod 66 pushes the moving plate 67 to move forward. The moving plate 67 drives the filter plate 68 to move forward, and the filter plate 68 moves to the top of the funnel 58, so that the hydrochloric acid entering the container can be filtered. At the same time, when the push rod 66 moves forward, it pushes the moving rod 69 to move, and the moving rod 69 drives the positioning plate 610 to move forward. The positioning plate 610 pushes the container to move, ensuring that the container is located between the two clamps 55, thereby improving the accuracy of the clamps 55 in fixing the container.
