The supporting frame 113 may be a ring structure, such as a circular ring frame or a rectangular ring frame, and the ring frame is provided with a notch. The support frame 113 may be provided inside with a partition rib 114, and the partition rib 114 divides the support frame 113 into two parts, which may be a go gauge accommodating part 111 and a no-go gauge accommodating part 112, respectively. That is, the support frame 113 has a go gauge accommodating portion 111 and a no-go gauge accommodating portion 112. Accordingly, the first notch 1131 is formed at one end of the gauge accommodating portion 111 located on the side of the partition rib 114. One end of the no-go gauge accommodating portion 112 located at the other side of the partition rib 114 is provided with a second notch 1132, and the first notch 1131 and the second notch 1132 are located at the same end of the supporting frame 113.

After the installation is completed, the outer surface of the first cover plate 115 may be flush with the first side of the support frame 113, that is, the thickness of the first cover plate 115 is the same as the depth of the stepped groove of the first side of the support frame 113. The outer surface of the second cover plate may be flush with the second side of the support frame 113, that is, the thickness of the second cover plate is the same as the depth of the stepped groove of the second side of the support frame 113. The first cover plate 115 and the support frame 113 may be connected by welding, screwing, riveting, or the like, and the second cover plate and the support frame 113 may be connected by welding, screwing, riveting, or the like.

The first notch 1131 in the gauge receiving portion 111 is sized to match the first gauge 212, so the gauge 210 hole also serves to guide the first gauge 212. The gauge body 211 can move in the gauge accommodating portion 111, and the movement of the first measuring portion 212 along the preset direction is realized through the holes of the gauge 210 and the limiting effect of the first cover plate 115 and the second cover plate.

The first measuring portion 212 is used for detecting the lower limit of the hole to be measured, and the size of the hole to be measured needs to be greater than or equal to the lower limit size, so that the working thickness of the first measuring portion 212 may be the lower limit size.

The second notch 1132 in the gauge receptacle 112 is sized to mate with the second gauge 312 so that the gauge 310 hole also serves to guide the second gauge 312. The caliper body 311 can move in the caliper receiving portion 112, and the movement of the second measuring portion 312 in the predetermined direction is achieved by the holes of the caliper 310 and the limiting effect of the first cover plate 115 and the second cover plate.

In addition, the bracket 110 is provided with the first go gauge trigger piece 220, the second go gauge trigger piece 230 and the go gauge indicator 240, and the bracket 110 is provided with the first no-go gauge trigger piece 320, the second no-go gauge trigger piece 330 and the no-go gauge indicator 340, so that the detection result can be visually displayed through the go gauge indicator 240 and the no-go gauge indicator 340, the detection efficiency can be further improved, the requirement on users can be reduced, and the labor cost can be saved.

The go gauge triggering unit 631 is in a triggering state when the go gauge 210 is qualified, and the go gauge indicator 240 and the power source 242 are turned on. I.e. the gauge 210 is able to enter the workpiece to be inspected, the gauge triggering unit 631 is triggered. The no-go trigger unit 641 is in a triggered state when the no-go gauge 310 passes the verification, and the no-go indicator 340 and the power source 242 are turned on. I.e., the no-go gauge 310 cannot enter the workpiece to be detected, the no-go gauge triggering unit 641 is triggered.

The go gauge triggering unit 631 comprises a switch of the go gauge 210, a first end of the switch of the go gauge 210 is connected with a second end of the first switching unit 620, a second end of the switch of the go gauge 210 is connected with a first end of the go gauge indicator 240, and a second end of the go gauge indicator 240 is connected with a first end of the second power source 242.

For example, the through gauge 210 switch may include the first conductive plate 222, the second conductive plate 231, and the third conductive plate 232 in the above embodiments. When the first measuring part 212 enters the hole to be measured, the first conductive sheet 222 contacts with the second conductive sheet 231 and the third conductive sheet 232, and the switch of the go gauge 210 is triggered. The no-go gauge 310 switch may be a switch including the fourth conductive plate 322, the fifth conductive plate 331 and the sixth conductive plate 332 of the above embodiments. When the second measuring part 312 is clamped on the upper surface of the hole to be measured, the fourth conductive sheet 322 is contacted with the fifth conductive sheet 331 and the sixth conductive sheet 332, and the switch of the go gauge 210 is triggered.

Of course, in practical applications, the go gauge indicator 240 may be a sound generating device or a display device, and the no-go gauge indicator 340 may be a sound generating device or a display device.

For example, the first indicator light 241 is driven to emit light. In practical applications, the electrical signal of the power source 242 passing through the passing rule triggering unit 631 may also be used as a control signal for displaying the detection result, for example, when the passing rule indicator 240 is a display device, the electrical signal may be used as a control signal for displaying a picture on the display device, and the display device starts to display the picture when receiving the electrical signal.

Similarly, in the above embodiment, after the no-go indicator 340 is triggered by the no-go trigger unit 641, the current of the power source 242 flows into the no-go indicator 340 through the no-go trigger unit 641, and the no-go indicator 340 is driven to display the detection result. For example, the second indicator lamp 341 is driven to emit light. In practical applications, the electrical signal of the power source 242 passing through the no-go trigger unit 641 may also be a control signal for displaying the detection result, for example, when the no-go indicator 340 is a display device, the electrical signal may be a control signal for displaying a picture on the display device, and the display device starts to display the picture when receiving the electrical signal.

It should be noted that the first terminal of the power source 242 may be a positive terminal, and the second terminal of the corresponding power source 242 is a negative terminal; or the first terminal of the power source 242 may be negative and the corresponding second terminal of the power source 242 may be positive.
