Rivet nut detection tool

The utility model relates to a rivet nut detection tool which is used for detecting a rivet nut, the standard outer diameter of a crumple portion of the rivet nut is d, the rivet nut detection tool comprises a tool body, the tool body is sequentially provided with a through groove and a stop groove in the length direction of the tool body, and one end, away from the stop groove, of the through groove is open. One end, close to the through groove, of the stop groove is open, so that the stop groove is communicated with the through groove; the groove width of the through groove is D1, the groove width of the stop groove is D2, and (D2/d) is larger than or equal to 0.88 and smaller than or equal to 1.08 and smaller than or equal to 1. When the rivet nut detection tool is used for detecting a to-be-detected rivet nut, the opening of the through groove in the tool body is aligned with the crumple part of the to-be-detected rivet nut after rivet pulling, the tool body is moved in the direction close to the to-be-de
