1. verification device with self-destruction protection function, it is characterized in that:

  • described verification device (1000) is provided with self-destruction protection operate portions and tests true operate portions to what true material to be tested (1004) was discerned, and described verification device (1000) uses with described true material to be tested (1004) is collaborative;

    Described self-destruction protection operate portions comprises air pressure change self-destruction protection operate portions, and the Starting mode of described air pressure change self-destruction protection operate portions starts for the variation by seal carrier (1003) internal gas pressure;

    The described verification device (1000) that is provided with described air pressure change self-destruction protection operate portions is by realizing that according to air pressure change the intermediate medium (316) of stretching, contracting is separated into first working chamber (1001) and second working chamber (1002) with described verification device (1000);

    Described first working chamber (1001) communicates with ambient atmosphere, described second working chamber (1002) is connected with the described seal carrier (1003) of the described true material to be tested of carrying (1004), and adopts the mode add air pressure or to subtract air pressure to be sealed into an integral body with described seal carrier (1003);

    Described intermediate medium (316) is subjected to the control of described second working chamber (1002) internal gas pressure size variation, realizes stretching, contracting, and controls the startup of described air pressure change self-destruction protection operate portions with this.
