[0002] A sanding machine is a mechanical device used to grind, polish and remove surface defects of workpieces. It usually uses a grinding wheel to process the surface of the workpiece to improve surface roughness, remove oxide layers, repair scratches, grind and polish, etc.

[0003] Some existing sanding machines are usually equipped with simple frames, and it is not easy to adjust the angle of the sanding machine. Therefore, when it is necessary to grind a workpiece with a bevel or inclined surface, the processing process becomes more difficult, and it is not convenient to use and has certain limitations. At the same time, the frames are often not movable and are not easy to adapt to different processing environments and workplaces. Therefore, those skilled in the art provide an adjustable movable frame for a sanding machine to solve the problems raised in the above background technology. Utility Model Content
