Oversized ceiling fan blade with nested structure and adopting plastic extrusion molding process

The invention belongs to the field of oversized ceiling fans, and particularly relates to an oversized ceiling fan blade with a nested structure and adopting a plastic extrusion molding process, the blade comprises a metal core material and a blade main body manufactured by adopting the plastic extrusion molding process, and a main body cavity penetrating through the head end and the tail end of the blade main body is formed in the blade main body. And the metal core material is fixedly arranged in the cavity of the main body. According to the blade, the blade body manufactured through the plastic extrusion molding process can be directly manufactured into the best wind dynamic blade shape, production is more convenient, and efficiency is higher; the whole weight of the blade is light, the load of a driving motor is reduced, and compared with an existing blade made of an aluminum alloy material, the price is lower; when a blade falling accident occurs, as the whole weight of the blade is light, the harmfulnes
