The invention discloses a prefabricated hollow slab inter-beam hinge joint steel bar adjusting device and a using method. The device comprises a bearing box, a steel bar adjusting part, a hydraulic clamp, a pressing part, an upper beam, a lower beam and stand columns. The two stand columns are connected with the bearing box. The upper cross beam and the lower cross beam are connected with the twostand columns in a sliding manner; and the pressing part is arranged between the upper cross beam and the lower cross beam, the upper end of the pressing part is connected with the upper cross beam, atelescopic end of the pressing part penetrates through the lower cross beam and is connected with the hydraulic clamp, the upper end of the steel bar adjusting part is connected with the hydraulic clamp, and the hydraulic clamp is installed on each stand column and connected with each stand column in a sliding mode. Damage to the U-shaped steel bars is small in a straightening process, and transverse connection of hollow
