The implementation principle of the embodiment of the application is as follows: the first driving part 11 is started to make the first lifting seat 12 do lifting motion, at this time, the second lifting seat 24 is linked with the first lifting seat 12 to apply pressure to the workpiece 1 to be detected, namely, pressure is applied to the elastic mechanical mechanism 2, so that the movable contact 3 on the elastic mechanical mechanism 2 is contacted with the stationary contact 4 on the mechanical humidity switch, at this time, the pressure value applied to the elastic mechanical mechanism 2 needs to be stabilized between 85 and 95 (g.f/cm < 2 >), then the second driving part 23 is started to make the second lifting seat 24 perform lifting motion, the workpiece 1 to be detected is pressed again, so that the range of the pressure value required to be applied to the elastic mechanical mechanism 2 is reduced, meanwhile, the second lifting seat 24 performs two lifting motions to exert the pressure to the workpiece to be detected, so that the phenomenon that the workpiece 1 to be detected is subjected to overlarge pressure or the speed of the second lifting seat 24 to press the workpiece 1 to be detected to be adjusted is overhigh, so that the workpiece is damaged is avoided, after detection, the third driving part 25 is started to adjust the elastic mechanical mechanism 2, and further, the range of the pressure value required to be applied to the elastic mechanical mechanism 2 is reduced to the humidity of the humidity switch is reduced, and the humidity of the humidity switch is reduced after the humidity adjustment is reduced.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
