[0019] See also Figure 1-Figure 4 The inside of the pull rod 75 is slidably connected with a guide rod 78, and both ends of the guide rod 78 are fixedly connected with the steam circulation pipe 3. By designing the guide rod 78, the pull rod 75 can be guided. The inside of the pull rod 75 is hinged with a rotating rod 79. A card slot 710 is provided inside the steam circulation pipe 3. An elastic card block 711 is carded inside the card slot 710. The bottom of the elastic card block 711 is fixedly connected with a second fixed block 712.
