HOLE PUNCH |
摘要 |
A hole punch (10) includes a base (12) and a lever system (20) to actuate a punch (18, 98). The lever system includes a first lever (22) having an end pivotally connected to the first end (14) of the base and a second lever (24) having an end pivotally connected to the second end of the base (16). Actuation of a free end (25) of the second lever causes the first lever to move. In one embodiment, a lock (140) 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 (32) having a first end operatively coupled to the first lever and a second end operatively coupled to the second lever. |
