description	The utility model discloses a live center which comprises a center mounting seat, a rotary structure arranged at the front end of the center mounting seat and a clamping nut arranged on the rotary structure. The rotary structure is composed of a rotary shaft, a shaft head arranged at the front end of the rotary shaft and fixed with the rotary shaft into a whole, and a clamping opening penetrating through the shaft head along the axis. The utility model provides the live center, a clamping mode is used for replacing a pressing mode, and the increase of axial pressure is well avoided, so that the deformation of a blade is avoided, meanwhile, the requirement of static friction force between the center and the blade is well reduced, the problem of vibration of the blade in the machining process is solved, and the service life of the blade is prolonged. The blade machining effect is greatly improved, the product quality is improved, unnecessary loss is reduced, and development and progress of enterprises and indus
