[0002] Because the steel pipes used in the construction industry have been placed for a long time, the construction industry, rental stations, and steel pipe factories generally use manual rust removal and painting methods when performing rust removal operations on pipe fittings. On the one hand, manual rust removal takes a lot of time and is not efficient; on the other hand, the labor intensity of manual rust removal is very high, which is not conducive to continuous operation; thirdly, the rust dust generated during the manual rust removal process due to long-term squatting and direct contact with the pipe fittings due to the close distance will cause certain harm to human health.

[0003] Using a handheld laser rust remover to remove rust from steel pipes can replace the above-mentioned manual rust removal method. However, the laser rust remover can only remove rust from the upper surface of the rusted pipe and cannot remove rust from the lower surface of the steel pipe at the same time. It needs to be turned over twice, which reduces the rust removal efficiency of the rusted pipe. Utility Model Content
