In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved, and the setting of the connecting shaft, the fixing seat, the pressing arm, the sliding plate, the transparent protective cover, etc. are used to realize the turning tool grinding. During grinding, a transparent protective cover is used to shield the working end while the turning tool grinder is powered on. This allows workers to observe the cutting process while preventing flying metal debris from injuring people, thereby protecting human operator safety. At the same time, when an accident occurs during the grinding process, the power is cut off in time, thereby protecting the safe use of the equipment. During use, after grinding a PCD tool, the traditional method is to stop the machine, disassemble the ground PCD tool, and then install the next PCD tool to be ground. This wastes a lot of time in disassembling and installing the PCD tool, resulting in poor continuity in PCD tool grinding, which in turn affects the efficiency of PCD tool grinding. For this reason, a new technical solution needs to be designed to solve this problem. Utility Model Content
