Meanwhile, in the process of rotation of the diamond seat 34, the resistance of the stone material horizontally received by the inner knife 36 is reduced so as to further reduce the resistance received by the primary grinding cavity, and the resistance of the stone material vertically received by the outer knife 35 is increased so as to enhance the grinding effect of the secondary grinding cavity. In this state, the hinge shaft connected with the connecting rod 32 on the grinding plate 30 is subjected to the outward pushing force of the material, so that the graph surrounded by the grinding plate 30 tends to be a regular dodecagonal shape (as shown in fig. 5), the volume of the primary grinding cavity is increased, the resistance applied to the primary grinding cavity during grinding is further reduced, and the secondary grinding cavity bears the main grinding pressure.
