Transmission mechanism of polishing machine

The utility model discloses a transmission mechanism of a polishing machine. The transmission mechanism comprises a first floating plate, a second floating plate, a first transmission assembly, a second transmission assembly and a third transmission assembly. The first floating plate movably connected with the rack and the second floating plate rotationally connected with the first floating plate are arranged, and the third transmission assembly is arranged on the first floating plate, so that the second floating plate can be pushed to turn over relative to the first floating plate within a certain angle, and the first floating plate is pushed to translate relative to the rack; the first transmission assembly and the second transmission assembly are arranged on the second floating plate, the multiple clamping jigs (workpieces) can be driven to rotate below the second floating plate, and under the linkage effect of the third transmission assembly, the multiple clamping jigs (workpieces) can rotate and deflect
