Punching and binding machine

The punching and binding machine comprises:

• a base (100);
• a bracket (200), wherein the bracket (200) is fixed to the base (100);
• a drive mechanism (300), wherein the drive mechanism (300) is connected to the bracket (200);
• a punching mechanism (400), comprising a limit plate (410), a plurality of punching cutters (420), and a plurality of adjustment pins (430), wherein the limit plate (410) is slidably connected to the drive mechanism (300), wherein each adjustment pin (430) is connected to a top of a corresponding punching cutter (420), and the limit plate (410) is provided with a plurality of limit grooves (411) that allows the plurality of adjustment pins (430) to slide and insert, wherein the drive mechanism (300) drives the limit plate (410) to move, and the plurality of adjustment pins (430) move between an abutting state and a sliding state, wherein in the abutting state, the plurality of adjustment pins (430) abut against a corresponding limit point of the corresponding limit grooves (411), and the limit plate (410) drives the corresponding punching cutters (420) to move synchronously, wherein in the sliding state, the limit grooves (411) allows the plurality of adjustment pins (430) to move within them;
• and
• a binding mechanism (500), wherein the binding mechanism (500) is slidably connected to the bracket (200), and the drive mechanism (300) drives the binding mechanism (500) to move between a compression ring position and a release position.
