[0022] like Figure 1-2 The detection instrument for detecting the minimum width of the nut wing shown includes a support frame 100, which is a base plate in the embodiment. Other configurations are also possible.

[0023] A positioning fixture 110 is provided on the support table chassis 100 , and a nut positioning groove 111 is provided on the positioning fixture 110 . The diameter of the nut positioning groove 111 is between the values ​​of the narrow part 201 of the nut 200 and the wide part 202 of the nut 200 .

[0024] In this way, the narrow portion 201 of the nut 200 falls into the nut positioning groove 111 , and the wide portion 202 of the nut 200 extends out of the nut positioning groove 111 .

[0025] A detection mechanism 120 is provided on the side of the support frame 100 close to the positioning tool 110 , and the end of the detection needle 121 of the detection mechanism 120 contacts the wing portion 203 of the nut 200 to be tested for detection.
