Especially, the corresponding vacuum state can be realized in the cover body 2 in the patent, so that the performance change of different heated objects under the vacuum state can be seen.

[0029] The specific embodiment of the scheme is that one end of the frame 13 is connected with a second motor 25 through a welding plate, the output shaft of the second motor 25 extends to a rotating gear 26, the outer wall of the rotating gear 26 is engaged with a gear plate 27 fixed on the workbench 12, and the frame 13 moves horizontally under the driving of the second motor 25.

Therefore, the two are combined to effectively detect the performance of materials in outer space under different temperatures.

[0034] The specific embodiment of the present patent is that the present patent designs an air extraction mechanism 5, which substantially extracts air in the cover body through a vacuum pump 9, so as to realize vacuum in the cover body 2. In addition, the valve-connected air guide pipe can ensure timely pressure relief in the cover body 2, and the double air guide pipes can be used as backup to prevent damage to one device and facilitate ventilation.

[0035] The clamping mechanism 6 is different from the existing cylinder transmission clamping work. First, the material is placed on the guide column 17 connected to the cross beam. The first clamping plate 15 connected to the first cylinder 14 is pushed inward, and under the action of the second clamping plate 18, the material can be horizontally clamped.
