Abstract
A device for actuating a punch includes a base for supporting the punch and an arm adjustably secured on the base. A barrel is secured to the arm for slidably receiving a shaft, and a lever is pivotally secured to the barrel and coupled to the shaft for moving the shaft to actuate on the punch with an increased torque. A spring is engaged with the shaft for biasing the shaft away from the punch. A seat is secured on the base and includes a bore for slidably receiving the lower portion of the arm. A latch may adjustably secure the arm to the seat according to the size of the punch.
