One end of the slider 26 is fixedly connected to one side of the rotating gear 25. One end of the fixing plate 28 is fixedly connected to the lower front end of the calibrator 11.

[0041] Through the meshing cooperation between the fixing plate 28 and the rotating gear 25, the fixing plate 28 can be inserted into the connecting groove 24 and the rotating rod 27 can be driven to rotate, so that the slider 26 slides along the thread track of the rotating rod 27 to provide clamping force for the air pressure sensor;
