At the same time, the protrusions 55 at both ends of the slide plate 53 slide in the slide groove 56 of the fixed cylinder 51. The elasticity of the spring 54 is used to make the bonding base plate 2 press against the diaphragm, so that the slide column 52 squeezes the pressure sensor 8, and the pressure value is obtained by the pressure sensor 8.
