The utility model discloses a metallographic phase grinding and polishing sample preparation stable pressurizing device, which comprises an adjuster top cover, a holder, an adjuster seat, a pressurizing spring and a pressurizing block, the adjuster top cover is rotatably arranged on the holder, the adjuster seat is slidably arranged in the holder, the pressurizing block is slidably arranged in the holder, and the pressurizing spring is arranged in the holder. A plurality of pressurizing springs are uniformly distributed between the regulator seat and the pressurizing block, one end of each pressurizing spring is fixedly connected with the bottom surface of the regulator seat, and the other end of each pressurizing spring is fixedly connected with the top surface of the pressurizing block. The friction force between the sample and the abrasive paper is controlled to increase and decrease, and the sample polishing speed is increased. The different heights of the sawtooth-shaped protrusions on the top cover of t
