[0054] The linkage assembly 39 comprises:

[0055] A wire wheel 391, one auxiliary rod 36 corresponds to a group of wire wheels 391, and a group of wire wheels 391 are symmetrically arranged at the bottom of each layer of the airing rack;

[0056] A steel wire rope 392, one end of the steel wire rope 392 is connected with the end of the auxiliary rod 36, and the other end is connected with the working rod 33 after passing through two symmetric wire wheels 391;

[0057] Both ends of the auxiliary rod 36 are rotatably connected with a sliding sleeve 393 through a torsion spring, the sliding sleeve 393 is arranged in a rectangle, the sliding sleeve 393 is slidingly installed on the corresponding slide rail 37, the mounting plate 31 is provided with a limiting piece 394, the limiting piece 394 is arranged obliquely, and the position of the limiting piece 394 corresponds to the top of the slide rail 37. According to actual needs, a tensioning wheel can be arranged to maintain the state of the steel wire rope 392, and the specific mounting mode and the structure of the tensioning wheel adopt the prior art, which will not be described in detail here.

[0058] The end of the dial piece 34 is wrapped with a silica gel layer 4, and the two sides of the auxiliary rod 36 are fixedly provided with passive rods 395 located directly below the limiting piece 394.

[0059] In the application, in order to reduce the damage caused by forcibly dialing the tobacco leaf by the dial piece 34, the auxiliary rod 36 and the linkage assembly 39 are arranged, the linkage action of the auxiliary rod 36 and the dial piece 34 is realized by arranging the auxiliary rod 36 and the linkage assembly 39, specifically, when the dial piece 34 moves along with the working rod 33, the tension on the auxiliary rod 36 is released, the auxiliary rod 36 moves downward under the action of its own weight, the sliding sleeve 393 at the end of the auxiliary rod 36 is separated from the limiting of the limiting piece 394, and because the sliding sleeve 393 with a rectangular structure can only move up and down and cannot rotate, the auxiliary rod 36 itself is deflected under the action of the torsion spring, so that the auxiliary rod 36 is deflected upward while moving downward, the door-shaped structure 38 of the auxiliary rod 36 is deflected upward, and the auxiliary rod 36 forms an inclined posture, so that the tobacco leaf automatically slides to one side and is concentrated.

[0060] It should be noted that the height of the inclined auxiliary rod 36 is still within the range of the opening 35 of the dial piece 34, so that the dialing effect can be continuously implemented. The power source of the auxiliary rod 36 is provided by the movement of the working rod 33, and the auxiliary rod 36 is deflected under the action of the torsion spring after being lowered and separated from the limiting piece 394.
