Beschreibung
Zusammenfassung:	The utility model discloses a pipe fitting concentricity calibrator, which relates to the technical field of pipeline concentricity calibration, and comprises a main rod, four first support rods are symmetrically arranged on the circumference of the surface of the main rod, and a light source emitter and a light target are respectively arranged at one end of the main rod of each of two devices, so that whether a pipeline is concentric or not can be measured; one end of the first supporting rod is rotationally connected to the main rod. The middle of each first supporting rod is rotationally connected with one end of a second supporting rod, the other end of each second supporting rod is rotationally connected to a pushing rod, and the pushing rod can slide back and forth on the main rod, so that the unfolding and shrinking scales of the four first supporting rods can be kept synchronous, and measurement work is facilitated; the spirit level is arranged behind the main rod, so that the positioning accuracy of
