The invention discloses a manual puncher based on a hinge rod-lever-hinge rod three-level force amplification mechanism, which comprises a puncher main body, a base and a pressing rod, a punch and a female die for punching are arranged in the base, and the manual puncher further comprises the three-level force amplification mechanism, the pressing rod pushes the pressing head to move towards the female die through a three-level force amplifying mechanism. A hinge rod-lever-hinge rod three-stage force amplification mechanism is adopted to obtain a larger force amplification coefficient, it is guaranteed that the structure size is not too large, the three-stage force amplification mechanism is obtained by sequentially connecting a hinge rod, a lever and a hinge rod in series, input force is amplified three times sequentially through the hinge rod, the lever and the hinge rod, and the force amplification efficiency is improved. Force is output through the push rod to complete the needed punching action, and an o
