NOVELTY - The utility model claims a grinding device of graphene powder, relating to the technical field of grinding, so as to solve the problem that the grinding device of the existing graphene powder is easy to remain after the grinding operation is finished; it is not convenient to process, comprising a main body; the upper part of the main body is provided with a fixing piece; the top of the main body is provided with an adjusting piece. by pulling the handle at the front end of the limiting column, so that the limiting column moves in the shrinking groove, and then the spring shrinks, so as to drive the moving column to move; the moving column will drive the moving piece to move, so the moving piece will drive the moving block at two sides to move in the sliding groove, so as to move the moving block; the clamping teeth at the inner side of the rectangular column at the front end of the moving block will drive the gear at the bottom of the rotating shaft in the rectangular groove to rotate, so that the gear will drive the rotating shaft to rotate; the rotating shaft will drive the control block to move; so the control block will drive the stopper to move; so it is convenient to clean the residual graphene in the device.
