This utility model discloses an anti-oxidation device for copper wire transmission. A fixed box is placed at the initial connection end of the traction mechanism, and the copper wire is then passed through the sealing colloid of the first and second openings. Antioxidant is poured into the solid box through a first liquid inlet pipe, continuously submerging the copper wire. The sealing colloid prevents significant liquid leakage during copper wire transmission. Once the antioxidant reaches a preset standard, the traction mechanism is activated, guiding the copper wire through the antioxidant in the solid box. The fixed box possesses high mechanical properties and rigidity, ensuring long-term use. This device solves the technical problem of existing plastic bottles being too soft, having poor mechanical properties, and easily damaged, leading to antioxidant leakage and affecting the anti-oxidation process of the copper wire.
