When the driving output end of the lifting drive mechanism 6 contracts downward, the transmission assembly 7 drives the storage inner box 5 to quickly rise into the high-temperature warehouse 3.

[0023] Specifically, in this embodiment, the test box 1 is made of high-quality carbon steel plate material. In addition, the surface of the test box 1 is treated with phosphating electrostatic spraying to improve the durability of the test box 1. The placement box 2 is made of SUS304 stainless steel. The high-temperature warehouse 3 is provided with a plurality of heating holes, and the low-temperature warehouse 4 is provided with a plurality of cooling holes. The heating component is preferably a SUS304 stainless steel high-speed electric heater.

The SUS304 stainless steel high-speed electric heater heats the high-temperature warehouse 3 through each heating hole, and the air cooled by the evaporator cools the low-temperature warehouse 4 through each cooling hole.

[0024] The present technical solution utilizes a lifting drive mechanism 6 in cooperation with a transmission mechanism to drive the storage inner box 5 to quickly lift and move in the high-temperature bin 3 and the low-temperature bin 4, so that the test product in the storage inner box 5 can be quickly switched between high-temperature scenes and low-temperature scenes.
