A universal clamp of wind driven generator blades is used for resolving the problem that the existing wind driven generator blades are high in cost, frequent in replacement and the like in the production, storage, transportation and installation processes. The universal clamp comprises a blade root portion clamp and a blade wing section clamp, the blade root portion clamp is assembled with a root portion cylinder, the blade wing section clamp is assembled with a blade wing portion, a zigzag insertion-connection face with a cylindrical boss is respectively arranged at the top ends of the blade root portion clamp and the blade wing section clamp, a zigzag insertion-connection face with a round hole type groove is respectively arranged at the lower ends of the blade root portion clamp and the blade wing section clamp, and cylindrical bosses at the top ends are matched with the round hole type grooves at the lower ends and the upper zigzag insertion-connection face and the lower zigzag insertion-connection face. The universal clamp is capable of providing clamping effects and stress points for blades in the production, storage and transportation of the blades and the whole process of wind power installation, is capable of achieving stacking of a plurality of blades and suitable for wind driven generator blades of various types and has good generality.
