In addition, the rotation of the outer shaft 52 will drive the fixed groove ring 62 and the nozzle 1 63 to rotate. When the grinding middle shaft 42 rotates, it will drive the central delivery pipe 64, the bottom ring 65 and the nozzle 2 66 to rotate, so that the nozzle 1 63 and the nozzle 2 66 spray the grinding fluid more comprehensively.
