[0030] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an adapter structure is arranged on the wall surface of the solid plate 21 for adapting and fixing pressure vessels of different sizes, and the adapter structure comprises: a first electric cylinder 31, a splint 32, a solid block 35, an adapter plate 36 and a rotating shaft 37, the first electric cylinder 31 is arranged in front of each solid plate 21, the splint 32 is fixedly connected to the side wall surface of each first electric cylinder 31, the solid block 35 is fixedly connected to the upper and lower wall surfaces of each splint 32 symmetrically, the adapter plate 36 is rotatably connected between each pair of symmetrical solid blocks 35, and the rotating shaft 37 is fixedly connected to the wall surface of each adapter plate 36 symmetrically, the splint 32 and the rotating shaft 37 on each side are symmetrical to each other, and the symmetrical splint 32 can fix the pressure vessel.

[0031] As shown in Figure 1 ,Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in the drawings, the clamping plate 32 is a rectangular plate, the adapter plate 36 is an arc-shaped plate, and the rotating shaft 37 is a cylindrical shape. The adapter plate 36 is rotatably connected between the symmetrical fixed blocks 35 through the symmetrical rotating shafts 37. The upper and lower symmetrical adapter plates 36 on each side are located at the upper and lower wall surfaces of the clamping plate 32. The adaptive structure further includes a front plate 30, a fixed rod 40, a second electric cylinder 41, and a connecting rod 42. The front plate 30 is fixedly connected to the front wall surface of each fixed plate 21. The first electric cylinder 31 is fixedly connected to the side wall surface of the front plate 30. The fixed rod 40 is fixedly connected to the outer arc surface of each adapter plate 36. The second electric cylinder 41 is fixedly connected to the front plate 30 in the front and rear direction of each first electric cylinder 31. The connecting rod 42 is rotatably connected to the end of the second electric cylinder 41. The other end of the connecting rod 42 is rotatably connected to the fixed rod 40. The adaptive structure further includes a damping spring rod 22 and a bottom plate 23. The damping spring rod 22 is fixedly connected to the side wall surface of each fixed plate 21.

[0036] In summary, by arranging the guide structure, the friction when the pressure container moves can be reduced when the pressure container is placed, thereby reducing the abrasion when the pressure container moves and preventing damage when the pressure container moves.
