The invention discloses a novel metal screw screw derusting device, which comprises a base, a first sleeve, a second sleeve, a rack, a fixed rod, a spray head, a water storage tank, a submersible pump, a water inlet pipe, and a first motor , the first rotating shaft, the drain pipe, the drain valve, the rust removal sleeve, the wire brush, the bolt, the threaded rod, the fixing sleeve, the fixing column, the fixing splint, the second electric motor, the second rotating shaft and the gear. This new type of metal bolt screw derusting device has a reasonable structure and novel design, which realizes the treatment of metal rust residue on the surface of the bolt screw, which is convenient for the fixed use of various facilities through bolts in the later stage, and avoids the difficulty of disassembly caused by the rust of the bolts. And it is difficult to tighten and fix the process, prolong the service life of the bolt, reduce the cost, ensure the stable placement of the bolt during the derusting process, facilitate the derusting of the bolt, and realize the circular derusting of the vertical direction of the bolt, and the practical value is relatively high. High, suitable for promotional use.
