It should be understood that one pusher module 300 is hidden in the consumable pushing device in fig. 9, the first gear 3021, the second gear 3022, the driving wheel 303, and the driven wheel 304 which are currently visible correspond to the pusher module 300 which is already hidden, and the relevant parts corresponding to the pusher module 300 shown in the figure are not visible due to the shielding of the bracket 100.

In some of these embodiments, the driven wheel 304 is coupled to the support 100 via an adjustment handle 110, and the adjustment handle 110 is used to adjust the pressure between the driven wheel 304 and the driving wheel 303. The adjusting handle 110 is located on a side surface between two installation positions of the bracket 100, and the two adjusting handles 110 are respectively located on two opposite side surfaces of the bracket, so that mutual interference between different pusher modules 300 can be avoided.

As shown in fig. 4, 8 and 9, in the present embodiment, the adjustment handle 110 includes a handle body 101, an elastic member 104 and a connecting rod 105.

The driven wheel 304 is rotatably disposed on the handle body 101 of the adjustment handle 110, and the driven wheel 304 can rotate around its own axis, and since the driven wheel 304 needs to rotate continuously during the pushing process of the consumable 400 to be pushed, it needs to have good rotation characteristics, and therefore, the driven wheel 304 can be mounted by using a structure such as a ball bearing 3041 to reduce the rotation friction force of the driven wheel 304.

One end of the handle body 101 is rotatably connected with the bracket 100, the handle body 101 can rotate around the joint of the handle body 101 and the bracket 100, and the handle body 101 and the bracket 100 are only required to be rotatably connected in the adjusting process, so that one end of the handle body 101 can be connected with the bracket 100 through the pin 1011 and other structures, and cost reduction is facilitated.

The other end of the handle body 101 is provided with a through hole, the connecting rod 105 penetrates through the through hole, and the connecting rod 105 is connected with the handle body 101 in a sliding mode. The connecting rod 105 comprises a first end and a second end which are opposite, the first end of the connecting rod 105 is connected with a connecting hole arranged on the support 100, the relative position of the first end of the connecting rod 105 and the support 100 is adjustable, and the elastic piece 104 is respectively abutted against the handle body 101 and the second end of the connecting rod 105.

The direction of the connecting rod 105 is perpendicular to the direction of the rotation axis between the handle body 101 and the bracket 100, and when the connecting rod 105 is fixed to the bracket 100 and the handle rotates within a certain range, the bracket 100 body can slide along the connecting rod 105.
