Its main purpose is to make the mold workpiece have a smooth surface or mirror gloss, so as to meet the requirements of aesthetics and precision of the mold workpiece. Currently, the commonly used tools for polishing are polishing wheels, oil stones, etc. Since oil stones are small in size and flexible in use, most mold workpieces with small size or complex angles are often polished manually with oil stones. When people use oil stones for polishing, they need to use oil stone clamps to clamp and fix the oil stone blocks.

[0003] The oilstone clamp currently used for clamping the oilstone is mainly composed of a clamp handle, a mounting groove on the clamp handle and a rubber ring fixed on the clamp plate for fixing the oilstone. Although the oilstone clamp of this structure can achieve reliable fixation of the oilstone and convenient replacement of the oilstone, on the one hand, since the oilstone clamp of this structure can only install one oilstone at a time, the continuous use time of the oilstone clamp is relatively short when in use, and the oilstone clamp is easily used inefficiently due to the long time it takes to replace the oilstone during use. On the other hand, since the oilstone clamp is mainly used to manually press the rubber ring to achieve reliable fixation of the oilstone on the clamp handle, the oilstone surface is relatively smooth, which may cause relative sliding between the oilstone and the oilstone clamp during use, thereby making the oilstone grinding efficiency of the mold relatively low.
