Beschreibung
Zusammenfassung:	The invention relates to the technical field of breathing machine accessories, in particular to an axial flow fan with a fan blade edge folding structure. The axial flow fan comprises a driving fan body and lateral driving blades, and the upper end of the driving fan body is fixedly connected with a top rotating cover through a top rotating shaft. According to the axial flow fan with the fan bladeedge folding structure, the top rotating cover with an external mounting cylinder on the outer side is mounted on the top rotating shaft at the upper end of the driving fan body, the lateral drivingblades are mounted through an internal assembling cylinder on the inner side face of the top rotating cover and a mounting slot in the outer side face of the top rotating cover, and then a longitudinal transmission shaft on the inner side face of the top rotating cover is in meshing transmission with a lateral assembling rotating shaft, so that the lateral driving blades are conveniently limited and mounted; and an interna
