During the detection, after setting the required model of the inner diameter detection member 2 and the outer diameter detection member 3, the nut to be tested is aligned with the detection groove 11 and placed in for detection. The annular detection groove 11 formed by the two is more convenient for the nut to be placed in to observe whether it is suitable. Among them, the first positioning part 7 and the second positioning part 9 of the inner diameter detection member 2 and the outer diameter detection member 3 of different models are both adapted to the first positioning groove 5 and the second positioning groove 6, and the models of the two are determined by the first detection part 8 and the second detection part 10.
