The length of the T-shaped slide groove 5 is certain so that the sliding range of the external expansion box 3 is limited. At the same time, the T-shaped structure of the T-shaped slider 6 and the T-shaped slide groove 5 prevents the external expansion box 3 from falling out of the main box body 1. During the volume expansion and adjustment process, the sealing layer 2 of the main box body 1 is always embedded in the inner side of the rubber plate 4 of the external expansion box 3. At the same time, the tight fit between the sealing layer 2 and the rubber plate 4 can play a role of multiple sealing.

[0026] like Figure 1 , Figure 3 and Figure 6As shown, a bottom support plate 8 is fixed to the lower inner side of the main box body 1, and the bottom support plate 8 is provided with two rectangular openings, and a docking plate 9 is fixed to the lower inner side of the external expansion box 3, and the docking plate 9 is provided with two rectangular convex plates, and the rectangular openings of the bottom support plate 8 coincide with the rectangular convex plates of the docking plate 9; a vacuum exhaust pipe 10 is connected to the outer side of the middle part of the external expansion box 3, and a sealing door plate 11 is rotatably installed on one side of the main box body 1; the bottom support plate 8 inside the main box body 1 is used to carry environmental experiment samples or sample containers, and the bottom support plate 8 and the docking plate 9 are located in the same horizontal plane and can be embedded with each other, so as to facilitate the expansion adjustment between the main box body 1 and the external expansion box 3, and there will be no situation where the environmental experiment samples or sample containers are placed unstable due to the difference between the bottom support plate 8 and the docking plate 9. According to the requirements of the environmental experiment, the interior of the main box body 1 and the external expansion box 3 can be evacuated through the vacuum exhaust pipe 10, and the sealing door plate 11 is convenient for opening and closing to take and place environmental experiment samples or sample containers.
