In this embodiment, the back of the second alloy support bar 5 is provided with a plurality of first protrusions, which are embedded in the guide rail at the corresponding position. A plurality of screws corresponding to the position of the second protrusions are passed through the guide rail and screwed to the second protrusions to fix the second alloy support bar 5, thereby facilitating maintenance. In addition, the second alloy support bar 5 includes multiple length sections, which can reduce the difficulty of processing the alloy support bar and help simplify the process.

[0036] In addition, the opening ends of the first tobacco channel 8 and the second tobacco channel 9 formed by the second alloy support bar 5 are trumpet-shaped. Specifically, the second alloy support bar 5 is inclined outward by 10° near the opening end.
