However, this driving method has a drawback: to avoid damaging the motor due to excessive torque, the bending machine uses a small driving gear to drive a large driven gear. This driving method is very slow and not conducive to mass production. To solve the above technical problems, the machine structure needs to be improved. Summary of the Invention
