Inside the fixed seat 10, a baffle 12 is slidably sleeved. The lower end of the baffle 12 is fixedly connected with a connecting rod 13. The connecting rod 13 is slidably connected with the fixed seat 10. One end of the connecting rod 13 close to the inner wall of the fixed seat 10 is fixedly connected with a guide block 14. The guide block 14 is slidably connected with the fixed seat 10. Inside the guide block 14, a guide rod 15 is slidably sleeved. The guide rod 15 is fixedly connected with the fixed seat 10. A spring 16 is arranged on the outer side of the guide rod 15. One end of the spring 16 is fixedly connected with the fixed seat 10, and the other end of the spring 16 is fixedly connected with the guide block 14. By designing the spring 16, the acting force of the spring 16 can act on the guide block 14. A blowing mechanism 9 is arranged inside the furnace body 1.

[0021] Refer to Figure 1 、 Figure 2 The blowing mechanism 9 includes an air delivery pipe 91. The top of the hot air blower 7 is provided with an air delivery pipe 91. The outer side of the air delivery pipe 91 is rotatably sleeved with a rotating pipe 92. The rotating pipe 92 is connected to the furnace body 1 through a bearing. The rotating pipe 92 is hermetically and rotatably connected to the furnace body 1. By designing the rotating pipe 92, the rotating pipe 92 can rotate relative to the furnace body 1. The circumferential surface of the rotating pipe 92 is fixedly connected with air outlets 93. The number of the air outlets 93 is multiple.
