The upper part (421) is installed on the first guide seat (43) and connected to the chip discharge hole of the drill bit (41). The lower part (422) is installed below the binding platform (2). The diameter of the upper part (421) is smaller than that of the lower part (422). When the drill bit (41) moves longitudinally, the upper part (421) slides longitudinally inside the lower part (422). The waste paper scraps in the drill bit (41) are discharged from the machine core after passing through the upper part (421) and the lower part (422) of the feed tube (42).

10. The mechanism of a fully automatic riveting and binding machine according to claim 6, characterized in that: The frame (1) has a slide rail (18), and a third guide seat (71) has a slider (712) protruding from it. The slider (712) is engaged with the slide rail (18). When the lower riveting device (7) moves longitudinally, the slider (712) slides in the slide rail (18). An opening is provided below the slide rail (18). When the lower riveting device (7) makes an arc motion, the slider (712) disengages from the slide rail (18) through the opening.
