The invention discloses a tellurium- cadmium-mercury vertical liquid-phase extension sample holder. Three closed covering pressure strips are arranged on the top end, the left side and the right side of a sample holder plane; and a clamp is fixed on the bottom end of the sample holder plane. Each of the three covering pressure strips and the clamp has an inclined plane with an angle of 45 degrees with the sample holder frame, and contacts with the edge of a substrate. The clamp is fixed on the sample holder plane by a fastening screw. The sample holder is applicable to the vertical liquid-phase extension growth of the tellurium- cadmium-mercury vertical; when the substrate is clamped and fixed, the covering pressure strips are covered and pressed on the upper part, the left side and the right side of the substrate, so that mother liquor can be prevented from permeating to the back surface of the substrate from the front surface during the extension; the clamp is used for tightly pressing the bottom end of the
