The loading platform 2 is arranged on the test bench 1 for placing the test sample. The heating furnace 3 is covered by the loading platform 2. The translation component 4 is arranged on the test bench 1 and is connected to the heating furnace 3 for driving the heating furnace 3 to move linearly so that the sample placed on the loading platform 2 is located in the middle of the heating furnace 3.
