Air pipes 38 are fixedly installed on both sides of the three-way pipe 37. One end of the air pipe 38 is fixedly installed on one side of the airbag 12.
[0032] A door body 21 is rotatably connected to one side of the shell 2, and mounting frames 22 are fixedly installed on both sides of one end of the fixed frame 1. A slide groove 23 is opened on one side of the mounting frame 22, and a moving block 25 is slidably connected to the inner side surface of the slide groove 23. A moving plate 24 is fixedly installed at one end of the moving block 25, and an adjusting rod 26 is rotatably connected to the bottom of the moving plate 24, and the adjusting rod 26 is threadedly connected to the inside of the mounting frame 22.
[0033] When in use, the user can clamp the edge of the bed between the movable plate 24 and the mounting frame 22, and then rotate the adjustment rod 26 to make the adjustment rod 26 threadedly connected inside the mounting frame 22, and then drive the movable plate 24 to move upward and abut against the bottom of the bed, so as to limit the fixed frame 1;
[0034] When the moving plate 24 moves, the moving block 25 can slide on the inner side of the sliding groove 23 , so as to limit the moving plate 24 .
[0035] Both ends of the outer side of the piston tube 34 are fixedly mounted with fixing rings 35 , and the fixing rings 35 are fixedly mounted on the inner side of the housing 2 .
[0036] The two mounting frames 22 are respectively disposed on two sides of the housing 2 .
