[0002] Existing high-temperature test systems such as Figures 16-17 shown are generally composed of a high-temperature furnace body 12, a high-temperature furnace control system (testing machine 14) + a high-temperature extensometer / video optical extensometer, a high-temperature fixture structure 11, and a support structure 10. The heating element in the high-temperature furnace body can realize high-temperature tests on specimens in an environment of 1100 - 1400 °C. The reasonable arrangement of the heating element in the furnace achieves relatively uniform temperature. The high-temperature furnace control system controls the temperature in the furnace. The high-temperature extensometer / video optical extensometer measures the elongation / compression of the specimen. The high-temperature fixture structure 11 fixes and positions the specimen. The existing high-temperature test system has the following defects:

[0003] ① When conducting tests on different specimens, if the lengths of different specimens are different, the experimental area of the specimen may not be in the isothermal zone of the high-temperature furnace, resulting in inaccurate actual heating temperature. The existing high-temperature furnace test system cannot make fine adjustments, cannot change the position according to the specimen size, and replacing different specimens requires adjusting the entire system to a suitable position, which is time-consuming and laborious;

[0004] ② The specimen is usually not as long as the height of the furnace body of the high-temperature furnace. The temperature in the furnace is too high, and a special high-temperature fixture made of heat-resistant alloy needs to be equipped. The high-temperature fixture has a force value limit and sometimes cannot meet the test requirements. At the same time, the costs of the high-temperature fixture and the high-temperature furnace body are relatively high;

[0005] ③ The high-temperature furnace is fully enclosed, with only a small observation window left, and it is impossible to clearly see the real-time state of the specimen. Summary of the Invention
