The rear end of the card block 204 in the installation cavity 203 is fixedly connected to the wiring harness 206, the winding disk 207 is movably installed in the center of the installation cavity 203, and the card slots 208 are opened on both sides of the protective box 201. The outer side of the card slot 208 is also provided with a slide groove 209, the winding disk 207 and the card slot 208 match each other, and the outer side of the winding disk 207 is also fixedly installed with an adjusting handle 210. The inner side of the wiring harness 206 is fixed on the winding disk 207, and a support seat 211 is fixedly installed in the installation cavity 203 inside the spring 205. A sealing ring 212 is also fixedly installed on the outer end of the positioning frame 202, and the positioning frame 202 is also filled with moisture-absorbing cotton 213.

[0026] Specifically, the pneumatic measuring instrument 100 is a device for quickly detecting the dimensional accuracy of the motor shaft. The pneumatic measuring plate 102 in the pneumatic measuring instrument 100 can be stably engaged and fixedly installed in the protective box 201 at the rear end of the display 101 through the blocks 204 at both ends after use, thereby forming an integral structure with the display 101. While safely protecting the multiple groups of measuring components at the upper end of the pneumatic measuring plate 102 when not in use, the pneumatic measuring instrument 100 that forms the integral structure can also improve its convenience in carrying, transporting and storing. At the same time, after the pneumatic measuring plate 102 is engaged and installed in the protective box 201, the bottom of the pneumatic measuring plate 102 can also be pressed against the front of the positioning frame 202 in the protective box 201, and then through the sealing ring 212 and the front end of the positioning frame 202 The moisture-absorbing cotton 213 improves the sealing and moisture-proof performance of the pneumatic measuring plate 102 after installation.
