Rapid thermal shock device

The invention relates to a rapid thermal shock device. The rapid thermal shock device comprises a heating sample loading platform, an atmosphere protection shell and a temperature acquisition device, according to the heating mechanism of the device, carbon paper instantly generates a large amount of heat when current passes through due to the Joule heat principle. The heating sample loading platform comprises an insulating and heat-insulating base, a liftable objective table, a carbon paper pressing and conducting module and a distance adjusting slide rail. The carbon paper pressing module can be adjusted to move up and down to press the carbon paper and conduct electricity; the heating distance of the sample can be adjusted by manually adjusting the lifting of the heating sample loading platform; the atmosphere protection shell comprises a sample inlet, an air inlet, an air outlet, a wire inlet, an atmosphere test port and a temperature test port, the air inlet and the air outlet are connected through an air
