A limiting plate 17 is fixedly connected to the outside of the end of the second connecting rod 16 away from the first connecting rod 14. A moving block 15 is provided outside the first connecting rod 14. The outside of the moving block 15 is arranged between the limiting block 13 and the second connecting rod 16. The outside of the end of the second connecting rod 16 away from the first connecting rod 14 is arranged inside a plurality of connecting plates 3. A first connection port 5 is opened inside each of the plurality of connecting plates 3. A second connection port 18 is opened inside the connection block 2. One end of the second connecting rod 16 passes through the inside of the connection block 2 and the connecting plate 3 and is arranged outside the limiting mechanism 4. Notches 8 are opened at both ends inside the first fixing block 6. The outside of the moving rod 9, the small spring 10, and the connecting head 11 are all arranged inside the notch 8. The limiting mechanism 4 includes a first fixing block 6. One side of the first fixing block 6 is fixedly connected to the outside of one of the connecting plates 3. The other side of the first fixing block 6 is fixedly connected with a second fixing block 7. Moving rods 9 are provided on both sides inside the first fixing block 6. The outside of a plurality of moving rods 9 is arranged on both sides inside the limiting mechanism 4. A connecting head 11 is fixedly connected to the outside of one end of the moving rod 9. A moving plate 12 is fixedly connected to the outside of the other end of the moving rod 9. One end of the moving rod 9 passes through the inside of the first fixing block 6 and is fixedly connected to the outside of the moving plate 12. The outside of the connecting head 11 is closely attached to the bottom of the limiting block 13; when the connection block 2 is placed between a plurality of connecting plates 3, at this time, the second connecting rod 16 is placed inside the first fixing block 6. The limiting block 13 is driven to move by the second connecting rod 16 being placed inside the first fixing block 6. When the limiting block 13 moves to the bottom of a plurality of connecting heads 11 and continues to move the limiting block 13 upward, at this time, a plurality of connecting heads 11 are squeezed and move backward. After the connecting heads 11 move backward, the outside of the limiting block 13 exceeds the outside of a plurality of connecting heads 11.

When the limiting block 13 moves to the bottom of a plurality of connecting heads 11 and continues to move the limiting block 13 upward, at this time, a plurality of connecting heads 11 are squeezed and move backward. After the connecting heads 11 move backward, the outside of the limiting block 13 exceeds the outside of a plurality of connecting heads 11. At this time, the small spring 10 provided outside the moving rod 9 drives the connecting head 11 to reset to achieve the effect of limiting the limiting block 13. And the limiting plate 17 fixedly connected to the outside of one end of the second connecting rod 16 limits the second connecting rod 16, so that the limiting block 13 cannot continue to move forward. And through a plurality of connecting heads 11, the limiting block 13 cannot move backward. By limiting the limiting block 13, the effect of limiting the second connecting rod 16 is achieved. By limiting the second connecting rod 16, the effect of limiting the connecting block 2 is achieved. By limiting the connecting block 2, the effect of installing the air spring body 1 is achieved. When the air spring body 1 needs to be disassembled and replaced, by pulling out the limiting plates 17 provided on both sides of the first fixing block 6 backward, the moving rod 9 is driven to move. By moving the moving rod 9, the connecting head 11 is driven to move. By moving the connecting head 11, the effect of releasing the limit on the limiting block 13 is achieved. By releasing the limit on the limiting block 13, the effect of being able to take out the second connecting rod 16 is achieved. By taking out the second connecting rod 16, the effect of being able to take out the connecting block 2 is achieved. By taking out the second connecting rod 16, the effect of taking out the air spring body 1 is achieved, achieving the effect of quickly disassembling the air spring body 1. By passing the second connecting rod 16 through the inside of a plurality of connecting plates 3, the effect of limiting the connecting block 2 is achieved. By limiting the connecting block 2, the effect of limiting the air spring body 1 is achieved. And by the rubber pads 19 provided on the side surfaces of a plurality of connecting plates 3 contacting the connecting block 2, the gap between the connecting block 2 and the plurality of connecting plates 3 can be filled, preventing the connecting block 2 from shifting between the plurality of connecting plates 3.
