Optionally, as shown in fig. 10, the pusher bar assembly further includes a marker 470, the marker 470 being exposed at a gap between 300 and 100, the marker 470 being used to ensure that the mounting positions of the driving assembly 300, the pusher bar assembly 400, the cutting assembly 200, and the housing 100 with respect to each other are accurate. The limit tenon 480 is eventually supported by the limit seat 430 when the push rod assembly 400 is pulled to reset by the first elastic member 215, thereby ensuring that the distance of the reset stroke of the first cutter 213 reaching the cutting point where the two cutters meet each time during cutting is constant, and defining the distance as the cutting stroke of the device during cutting. Because the push plate 410 is close to the push plate hook 360 but not fixedly connected, the premise of realizing accurate cutting travel is that the distance of pushing the push plate 410 in the process of moving the rack 350 to the direction of the second limit switch 390 is consistent with the cutting travel, so that the proper depth of the push rod assembly 400 extending into the accommodating space of the driving assembly 300 needs to be positioned by observing the marker 470 during installation.
