The invention provides a fixture for pull rods and nuts, which comprises a pull rod, a nut and a pull rod gland, wherein n threaded holes a are uniformly arranged on the pull rod along the circumference; n+1 threaded holes are uniformly arranged on the pull rod nut along the circumference; through hole groups d matched with the threaded holes a are uniformly arranged on the pull rod gland; n+1 circular-arc shape long eyelets are uniformly arranged on the pull rod gland along the circumference corresponding to the threaded holes of the pull rod nut; and the radian length of the circular-arc shape long eyelets is more than the difference between 360/n and 360/n+1. The invention has the advantages that the pull rod and the nut can be fixed in one step through the fixture and the method, thereby ensuring convenient, quick, efficient and safe fixation.
