Then, the chromatographic column support plate will move downward along the chromatographic column support plate groove under the action of the first spring until it completely supports the chromatographic column. At this time, the fixation of the chromatographic column inside the first spring fixing frame is completed. Then, the chromatographic column telescopic feed tube is clamped with the chromatographic column through the chromatographic column telescopic feed tube placement groove. At this time, the connection between the chromatographic column telescopic feed tube and the chromatographic column is completed. Then, start the electric push rod, which will drive the movable piston to move to one side of the chromatographic column telescopic feed tube. Then, the filler inside the filler storage box will enter the interior of the chromatographic column through the chromatographic column telescopic feed tube.
