The elastic force of first elastic part 23 maintains the swing of first detection resistance component and second detection resistance component 25 to close to each other to hold the threaded part 200 to be detected. First micrometer 26 is fixed on first clamping mounting portion 211, and the detection head of first micrometer 26 is abutted on the side of second clamping mounting portion 221 towards first clamping mounting portion 211 along the swing direction of second clamping mounting portion 221, so that the change of detection data of first micrometer 26 can be triggered during the swing of second clamping mounting portion 221, to realize real-time detection and convenient observation. Then, the second clamping mounting portion 221 is swung in the direction away from first clamping mounting portion 211, the calibration thread gauge is placed into the first clamping detection area 27, and then the second clamping mounting portion 221 is released.

Since the first annular resisting sheet 2411, the second annular resisting sheet 2511 and the third annular resisting sheet 2521 are arranged and distributed along a spiral direction, when the thread gauge or the threaded part 200 to be detected is placed into the first clamping detection area 27, the circumference side of the first resisting roller 241, the second resisting roller 251 and the third resisting roller 252 can position and clamp the thread gauge or the threaded part 200 to be detected, and then the first annular resisting sheet 2411, the second annular resisting sheet 2511 and the third annular resisting sheet 2521 can be clamped into the thread groove of the thread gauge or the threaded part 200 to be detected, so that the detection of the single thread pitch diameter deviation can be realized. That is, in the embodiment, the first thread detection mechanism 20 is used for the detection of the single thread pitch diameter deviation of the threaded part 200, and the detection operation is more simple, convenient and fast.

In this embodiment, the second elastic member 33 can be a spring. The second elastic member 33 is compressed between the third abutting portion 312 and the fourth abutting portion 322, thereby driving the third abutting portion 312 and the fourth abutting portion 322 to swing away from each other. The structure is more simple and reasonable. The first detection abutting member 34 is pivoted on the third clamping mounting portion 313. The upper end of the first detection abutting member 34 is formed with a first detection limiting portion (not labeled in the figure). The second detection abutting member 35 is pivoted on the fourth clamping mounting portion 321.

The second clamping detection area 39 is used for clamping and positioning a calibration threaded gauge or a threaded part 200 to be detected. The second micrometer 36 is fixed on the fixed mounting portion 311. The detection head of the second micrometer 36 is abutted on one side of the fourth clamping mounting portion 321 facing the fixed mounting portion 311 along the swing direction of the fourth clamping mounting portion 321.

[0044] More preferably, in the embodiment, the second thread detection mechanism 30 further comprises a first limiting bolt 37a vertically screwed to the second fixed mounting base 31, and the upper end of the first limiting bolt 37a abuts against the side of the fourth abutting part 322 away from the second elastic member 33. The upper end of the first limiting bolt 37a can limit the second swing mounting arm 32 from swinging downward excessively, thereby playing a role of safe limiting, and the structure is safer and more reasonable.

Then, the first dial gauge 26 is cleared, and the zero adjustment operation of the first swing mounting arm 22 is completed.

[0050] Then, the second clamping mounting portion 221 is swung towards the direction away from the first clamping mounting portion 211, the gauge screw thread is taken out from the first clamping detection area 27, then the threaded part 200 to be detected is put into the first clamping detection area 27, and the second clamping mounting portion 221 is released, then the first detection contact assembly and the second detection contact assembly 25 are kept close to each other by the elastic force of the first elastic member 23 to hold the threaded part 200 to be detected, the threaded part 200 to be detected is positioned and clamped by the circumferential side of the first contact roller 241, the second contact roller 251 and the third contact roller 252, and then the first annular contact piece 2411, the second annular contact piece 2511 and the third annular contact piece 2521 are clamped into the thread groove of the threaded part 200 to be detected, and then the reading of the first micrometer 26 is taken, so that the detection of the single thread pitch diameter deviation of the threaded part 200 is completed.

[0051] When the detection of the full thread pitch diameter deviation is needed:
