[0027] The fixing assembly 3 includes a fixing pipe 31. A plurality of operating rods 35 are connected to the outside of the fixing pipe 31. A first limiting ring 32, a second limiting ring 33 and a third limiting ring 34 are connected to the inside of the fixing pipe 31. The first limiting ring 32 is rotatably connected in the first limiting groove 13. The second limiting ring 33 is rotatably connected in the second limiting groove 14. The third limiting ring 34 is rotatably connected in the third limiting groove 15. The fixing pipe 31 is threadedly connected in the connecting pipe main body 21. By providing the first limiting groove 13, the first limiting ring 32, the second limiting groove 14, the second limiting ring 33, the third limiting groove 15 and the third limiting ring 34, the first limiting ring 32 rotatably connected in the first limiting groove 13, the second limiting ring 33 rotatably connected in the second limiting groove 14 and the third limiting ring 34 rotatably connected in the third limiting groove 15 cooperate with each other to perform triple sealing on the reduction between the fixing pipe 31 and the soot blower main body 11, so that the gap between the fixing pipe 31 and the soot blower main body 11 will not only not affect the sealing effect of the connection structure, but also enhance the sealing effect of the connection structure.
