An oscillating sanding machine, comprising:

• a base column;
• an oscillating sanding spindle, being installed on the base column;
• a conveying unit, being installed on the base column so that the conveying unit is located under the oscillating sanding spindle and separated from the oscillating sanding spindle by a predetermined distance;
• a first driving unit, being installed on the base column and connected to a rotating shaft of the oscillating sanding spindle so as to drive the oscillating sanding spindle to rotate about an axis thereof;
• a second driving unit, being installed on the base column and connected to the oscillating sanding spindle so as to drive the oscillating sanding spindle to move to and from along the axis;
• and
• a third driving unit, being installed on the base column and connected to the conveying unit so as to drive the conveying unit;
• wherein the conveying unit comprises a first axle, a second axle, a plurality of fixing members, a support plate, and a conveying belt, in which the support plate is mounted on the base column so that two laterals of the support plate are coupled to the first axle and the second axle through the fixing members, and the first axle is connected to the third driving unit, while the conveying belt is routed around the support plate, the first axle, and the second axle;
• and
• wherein the fixing members coupled to two ends of the second axle are each coupled to a respective incline-adjusting structure, and the incline-adjusting structures are used to adjust an incline angle of the second axle with respect to a level.
