Thus, when the second end of the cross rod 72 moves up and down, the free end of the extension rod 152 moves up and down synchronously, and then the rotating shaft 151 is driven to rotate around its axis.

Example four:

as shown in fig. 12 to 15, the present invention is a fourth preferred embodiment.

The present embodiment is different from the first embodiment only in that: the specific structure of the transmission assembly is different, specifically, the outer side wall of the rotating shaft 151 extends laterally to form an extending rod 152 located outside the air intake channel 14, the transmission assembly 7 includes a movable element 76 and a push rod 761, the movable element 76 is rotatably disposed on the housing 62 and moves up and down synchronously with the second side of the driving wheel assembly 8, the movable element 76 is partially located below the extending rod 152, and the push rod 761 is located between the movable element and the extending rod 152 and can move up and down under the upward pushing of the movable element.
