The utility model relates to a pedestal-lifting-type chromatographic column fixing device, belonging to the technical field of experimental equipment. The chromatographic column fixing device is characterized in that two ends of a pedestal plate are in sliding connection with four chutes in a left side plate and a right side plate through four pulleys; centers of a middle aperture plate and an upper aperture plate are respectively fixed with outer rings of two bearings, 2-8 oval holes and 2-8 round holes are formed in the middle aperture plate and an upper aperture plate, and the center of each pair of the oval holes in the middle aperture plate and the center of each pair of round holes in the upper aperture plate are located on the same perpendicular line; two ends of the upper aperture plate and the middle aperture plate are respectively fixedly connected with the upper and middle parts of the left side plate and the right side plate; the top end of a screw rod is fixedly connected with a manual adjusting wheel, the upper and middle parts of the screw rod are respectively fixedly connected with two bearing inner rings, and the lower part of the screw rod is in threaded connection with a nut fixedly connected to the center of the pedestal plate. The chromatographic column fixing device is simple in structure and high in safety factor and is easy to operate and adjust; the height of a receiving bottle can be arbitrarily changed, the problem that the height of the receiving bottle is difficult to change after a chromatographic column is fixed can be solved, and the simultaneous use of the chromatographic columns of different standards can be met, so that the working efficiency is increased.
