The invention relates to a multifunctional binding machine. The multifunctional binding machine comprises a base, and a hole puncher and a stapler, which are fixedly arranged on the base. A hole punching inlet of the hole puncher is close to the first end of the base, and a stapling port of the stapler is close to the second end, opposite to the first end, of the base. The stapler comprises a staple guide part and a staple pressing part, wherein the staple guide part is fixedly arranged on the pedestal; the staple pressing part is connected to the tail end of the staple guide part through a shaft, and is used for pressing staples; the staple guide part comprises a base part and a staple discharging groove; the base part is connected with the staple pressing part through a shaft; the staple discharging groove is connected with the base part in a folding way, is used for accommodating the staples, and ensuring that the staples are positioned at a staple outlet; the staple outlet of the staple guide part is staggered with a staple pressing piece of the staple pressing part after the staple guide part is folded. According to the multifunctional binding machine, the staple guide part of the stapler has a folding structure, so that the stapler can be arranged below a pressure plate of the hole puncher, the size of the multifunctional binding machine can be far smaller than the hole puncher and the stapler, which are arranged in parallel, an office space is saved, and the multifunctional binding machine is convenient to use.
