[0034] Embodiment 2:
[0035] Reference Figure 1 and Figure 4 The inner wall of the through groove is plugged with an extensometer thermal insulation fiber 11, which is a material used to protect the extensometer from the influence of high temperature environment. When the extensometer is installed on the inner wall of the extensometer thermal insulation fiber 11, it can have a thermal insulation effect on the extensometer. The outer wall of the extensometer thermal insulation fiber 11 is plugged with the inner wall of the thermal insulation cotton 10. When the staff removes the observation glass 12, the through groove opened on the observation seat 9 can be exposed. By plugging the extensometer thermal insulation fiber 11 into the through groove, the extensometer thermal insulation fiber 11 is installed on the observation seat 9. At this time, the extensometer is plugged into the inner wall of the extensometer thermal insulation fiber 11, so that the extensometer can be installed.
[0036] Working principle: When the staff needs to test the sample, the staff will insert multiple sets of screws into the through holes opened on the observation cover 13, and at the same time, the rear ends of the multiple sets of screws are threadedly connected to the threaded holes opened on the observation seat 9, so that the observation cover 13 is fixedly installed on the front side of the observation seat 9. Then, the staff will insert the observation glass 12 from the top of the observation seat 9 downward to the inner wall of the observation seat 9, thereby completing the installation of the observation glass 12.
[0037] Subsequently, the staff will open the two sets of outer shells 2 to facilitate the installation of the test angle and sample between the two sets of furnace wire muffle tubes 8. Then, the two sets of outer shells 2 will be closed, and the two sets of furnace wire muffle tubes 8 will be electrically heated by the two sets of electrode assemblies 3 respectively, so as to provide a high-temperature test environment for the sample in the furnace. At this time, the staff can observe the condition of the sample in the furnace through the observation port on the observation cover 13 and the observation glass 12.
[0038] When the staff needs to collect the deformation of the sample in the furnace, the staff will pull out the observation glass 12 from the top of the observation seat 9 to release the plug-in effect with the inner wall of the observation seat 9, and then loosen multiple sets of screws so that the screws release the limiting effect on the observation cover 13, thereby facilitating the disassembly of the observation cover 13. When the observation cover 13 is removed, the staff will plug the extensometer thermal insulation fiber 11 into the through groove opened on the observation seat 9, and then plug the extensometer into the inner wall of the extensometer thermal insulation fiber 11. After the plug-in installation is completed, the observation cover 13 is reinstalled on the observation seat 9, and the extensometer thermal insulation fiber 11 and the extensometer are pressed and fixed by the observation cover 13 to complete the installation of the extensometer. At this time, the extensometer can be used to collect the deformation of the sample in the furnace.
