The first straight pipe is located above the second straight pipe. A first rotation table is arranged under the tail end of the first straight pipe. A second rotation table is arranged at the tail end of the second straight pipe. A first sliding sleeve is arranged at the bottom of the first rotation table. A second sliding sleeve is arranged on the second rotation table. A third straight pipe is arranged between the first sliding sleeve and the second sliding sleeve in an inserted mode. In this way, according to the three-section telescopic industrial cantilever, through matching of the first rotation table and the second rotation table, rotation adjustment of the first straight pipe and the second straight pipe is facilitated, through sliding of the first sliding sleeve and the second sliding sleeve on the third straight pipe, the total length is adjusted, the cantilever adopts to different working demands, the fixing performance is good, and the application range is broad.
