[0026] A further optimized solution is that the driving mechanism includes a motor 11, which is fixedly connected to the outer shell 1 through a connecting plate, and a threaded rod 12 is fixedly connected to the output end of the motor 11.

When placing the solid phase extraction column 6, it is necessary to first move the lever 19 on both sides to make the slider 13 drive the arc-shaped rubber plate 14 to move to both sides. After the solid phase extraction column 6 is placed, the lever 19 is released. Under the action of the spring 18, the slider 13 and the arc-shaped rubber plate 14 are pushed to move toward the solid phase extraction column 6, so that The arc rubber plate 14 contacts the solid phase extraction column 6, and the motor 11 is started again to move the movable plate 5 downward, so that the rubber plug 7 is inserted into the solid phase extraction column 6. According to the operating steps, the required solution is poured into the solution box 20.
