In a high-temperature working environment, a wind wheel made of a metal material resistant to high temperature needs to be used. The wind wheel in the prior art is composed of a rotating disc and a long strip-shaped blade. The number of rotating discs is multiple, and the rotating discs are divided into a left end rotating disc, a right end rotating disc and an intermediate rotating disc. The number of intermediate rotating discs is determined according to design. Each rotating disc is provided with multiple blade holes near the peripheral edge thereof. The number of blades is multiple. The left end rotating disc, the intermediate rotating disc and the right end rotating disc are arranged in parallel. Each blade passes through the corresponding blade hole of the left end rotating disc in sequence, then passes through the corresponding blade hole of the intermediate rotating disc, and then passes through the corresponding blade hole of the right end rotating disc. Then, the blade is fixed to the rotating disc by a process. The blade is manually passed through each corresponding blade hole. Since the number of blades is relatively large, the process required by this structure is high in cost and low in efficiency, which is not conducive to large-scale production. Moreover, the wind wheel of this structure is generally made of aluminum material. Since aluminum material is relatively soft, it is convenient for the production process operation, which also results in a relatively high material cost. SUMMARY
