Portable rust treatment machine

The invention discloses a portable rust treatment machine. The portable rust treatment machine comprises an electric rotation device, a fixing device, rubber rods, steel wires and a rotary rod. The power output end of the electric rotation device is provided with the rotary rod. The rotary rod is sleeved with the fixing device and the fixing device is close to the electric rotation device. The end face, far away from the electric rotation device, of the fixing device is provided with at least one rubber rod. The free end of each rubber rod is provided with the corresponding steel wire to form a brush-shaped structure. By the adoption of the portable rust treatment machine, the good derusting effect on bolts can be obtained, grinding and derusting can be conducted on the inner wall and the outer side of a pipeline, and meanwhile the roughness better than that of a general tool can be obtained; and the distance between the rubber rods is adjusted by rotating the rubber rods, derusting of bolts of different size
