The utility model particularly discloses a CCD (Charge Coupled Device) camera supporting and protecting device for a CZ single crystal furnace. The CCD camera supporting and protecting device comprises a base, a connecting rod and a protecting cover, two fixing rods are symmetrically fixed to the opposite positions of the inner wall of the base, and a connecting rod horizontally arranged in a sliding mode is connected between the two fixing rods. A supporting rod is arranged on the connecting rod in a sliding mode, and the end of the supporting rod is fixedly connected with a fixing block. A fixing ring integrally formed with the base is arranged on the inner side of the bottom edge of the base. And the protective cover covers the top opening of the base. The base has the advantages that the base is high in stability, and the camera is not easy to shift when the furnace is disassembled and assembled. The distance from the camera to the liquid level is consistent, so that the data uniformity is improved. The n
