    摘要: A hole punch includes a base and a lever system to actuate a punch. The lever system includes a first lever having an end pivotally connected to the first end of the base and a second lever having an end pivotally connected to the second end of the base. Actuation of a free end of the second lever causes the first lever to move. In one embodiment, a lock is operatively coupled to the lever system and engages the first and second levers to hold the levers in a stowed position. In another embodiment, the hole punch includes a third lever having a first end operatively coupled to the first lever and a second end operatively coupled to the second lever.
