[0002] The gauge has a simple structure and is usually a solid with accurate size and shape. This gauge is a thread plug gauge used for comprehensive inspection of internal threads, so that it simulates the maximum solid tooth profile of the measured thread, and checks whether the effective mean diameter of the measured thread exceeds the mean diameter of its maximum solid tooth profile, and at the same time checks whether the actual size of the bottom diameter exceeds its maximum solid size.

[0003] When the gauge is used to detect the internal thread of a workpiece, the through end and the stop end at both ends need to be connected to the internal thread respectively. However, when the existing gauge is used, when the operator uses one end for detection, the other end will hinder the operator's detection, affecting the detection efficiency. At the same time, both ends are provided with threads, which may easily cause damage during rotation. Utility Model Content

[0034] Working principle: When detecting the internal thread of the workpiece, first press the blocks 25 on both sides of the first connecting rod 1 into the installation bin 2, so that the two sets of limit plates 24 slide along the inner surface of the installation bin 2, the support spring 23 is in a compressed state, and the block 25 and the limit hole 26 cancel the engagement effect. At this time, the first connecting rod 1 and the second connecting rod 11 can be disassembled and the plug gauge through end 13 and the plug gauge stop end 14 on the two can be used respectively to detect the internal thread of the workpiece.

[0035] When the plug gauge through end 13 or the plug gauge stop end 14 is damaged or when inspecting the internal threads of workpieces of different specifications, first use a cross thread cutter to rotate the screw 36 so that the screw 36 and the nut 37 are separated by the thread. At this time, pull the screw 36 out from the surface of the socket 33 and the through hole 32, and then take the connecting block 3 out from the surface of the connecting groove 31.
