Fan blade

The utility model discloses a new fan leaf. The fan leaf in prior art has the disadvantages of high production cost, resource wasting and inconvenient moving due to adoption of aluminum alloy metal for the fan leaf. The utility model has a stiffener at the middle of the interior of a full plastic fan leaf, thus the whole fan leaf has a greatly enhanced bearing capacity of air resistance generated by high-speed rotating of the fan leaf and is not easy to break; and the potential danger is eliminated which exists when the fan leaf of a large fan is made of plastic. The stiffener is injected at the middle of the interior of the fan leaf during injection molding of the fan leaf, thus processing is quite convenient; raw material is saved; production cost is reduced; break possibility is avoided when the plastic fan leaf is aging; safety performance is ensured; and service life is prolonged. The utility model is widely applied in different types of large fans.
