[0021] It should be noted that the connecting component 1 includes a large flange 11 installed on the outside of the secondary combustion chamber. A small flange 12 is provided at the outer end of the large flange 11 via a fixing component 6. A through hole 13 is formed on the end face of the small flange 12. The connecting rod 2 is slidably connected to the through hole 13. (Refer to...) Figure 3 A groove is provided on the end face of the large flange 11 to facilitate the removal of the push plate 21.

[0022] In this embodiment, the connecting assembly 3 includes a U-shaped plate 31 fixedly connected to one side of the push plate 21. The U-shaped plate 31 is rotatably connected to the connecting rod 2. An insert rod 32 is inserted between the U-shaped plate 31 and the connecting rod 2. One end of the insert rod 32 is formed with a stop portion 33, and the other end of the insert rod 32 is embedded with a spring plunger 34. The telescopic end of the spring plunger 34 is locked to the upper surface of the U-shaped plate 31. By pressing the spring plunger 34, the insert rod 32 can be removed from the U-shaped plate 31, and then the push plate 21 and the connecting rod 2 can be separated, thereby replacing the push plate 21.

[0023] Furthermore, the positioning component 4 includes a positioning block 41, and the connecting rod 2 has a sliding groove 22. The positioning block 41 is slidably connected in the sliding groove 22. A spring 42 is fixedly connected between the positioning block 41 and the sliding groove 22. A notch 35 adapted to the positioning block 41 is opened on the end face of the U-shaped plate 31. The positioning block 41 is engaged with the notch 35. Through the engagement of the positioning block 41 and the notch 35, the U-shaped plate is locked, thereby positioning the push plate 21.
