Blade capable of recovering deformation

The utility model relates to the technical field of blades, in particular to a blade capable of recovering deformation, which comprises a base and a blade body, the blade body is vertically arranged on the base, and a buffer part is arranged at the front edge part of the blade body; the buffer part and the front edge part of the blade body are welded together, and the joint is polished smoothly; the buffering part is used for buffering the front edge part of the blade body; and the buffer part elastically deforms after being impacted and automatically restores after being impacted. The buffering part is arranged, and the supporting assembly and the filler are arranged in the buffering part; when the blades are impacted, the supporting sections are impacted firstly; the supporting section can generate elastic deformation, and meanwhile, the impact force is transmitted through the filler and the supporting assembly; the opening angle of a plurality of first connecting rods and second connecting rods on the supp
