The patent application number CN202320565747.6 discloses a rock slice polishing device, which drives its internal telescopic rod downward until the bottom of the grinding disc contacts the top of the rock slice by starting the cylinder, so as to achieve the purpose of adjusting according to the grinding thickness. After the adjustment is completed, the motor is started to make it The output end drives the rotating shaft to rotate, so that the grinding disk rotates to grind and polish the rock slices, which effectively improves the adjustability of the grinding disk. However, the angle of the polishing device during grinding is fixed, and the stone sample can only be grinded and polished in the vertical direction. When the stone sample is clamped and fixed, the side of the stone sample and other multiple angles cannot be grinded and polished. If other angles of the stone sample are to be continued to be grinded and polished, the clamping device needs to be loosened and the rock needs to be turned over.
