[0025] Working principle: when the operator is ready to start the multifunctional polishing machine for polishing work, first need to ensure that the sand belt 4 in the appropriate tension. For this, the operator can be adjusted by manually pulling the sand belt tensioning wrench 11 located in the front side of the sand belt tensioning plate 13, the tightness of the sand belt 4. Specifically, by pulling the sand belt tensioning wrench 11 inward, so that the sand belt tensioning plate 13 moves forward and compresses the sand belt tensioning spring 12. This will make the sand belt tensioning pad 14 to the sand belt 4 to exert pressure, so as to achieve the effective tension of the sand belt 4; conversely, loosen the sand belt tensioning wrench 11, the sand belt tensioning plate 13 will be under the action of the sand belt tensioning spring 12 back, reduce the pressure on the sand belt 4, to relax the sand belt 4 effect.
