Axial flow fan convenient to adjust

The utility model discloses an axial flow fan convenient to adjust, and belongs to the technical field of axial flow fans. A control box is arranged on the side wall of the shell, a plurality of supporting angle irons are fixedly connected to the bottom of the shell, rotating plates are arranged at the bottoms of the supporting angle irons, supporting discs are matched with the bottoms of the rotating plates, sliding ways are arranged on the circumferential outer walls of the supporting discs, and locking grooves are formed in the two sides of the sliding ways. After the rotating rod is pushed and pulled, the supporting column drives the rotating plate to rotate and then the rotating plate is locked through the locking cylinder, multi-angle convenient adjustment of the axial flow fan is achieved, the problem that angle adjustment of a common axial flow fan is inconvenient is solved, and the using convenience of the axial flow fan is improved; the dust blocking net is rapidly clamped to the axial flow fan thro
