description	The utility model provides a pull rod thread clearance eliminating device for a short-stress-path rolling mill. The device comprises an adjusting nut, a pressing nut, an end cover, a bearing seat, a pull rod, a high-elastic body buffer pad, a spherical pad and a bolt, a plurality of rectangular grooves which are evenly distributed are formed in the circumferential direction of the outer side of the pressing nut and the circumferential direction of the outer side of the adjusting nut, relative rotation between the pressing nut and the adjusting nut can be avoided by transversely arranging the plug pins inserted into the rectangular grooves, the structure is simple, assembly and disassembly are convenient, and the adjusting process is simpler and more convenient. And through the arrangement of the high-elastic body buffer cushion and surface contact, the phenomenon that the disc spring group is uneven after failure is avoided, the stress area is larger, and the stress is more uniform. The device is used in a sh
