<p>A hole puncher has a base (10, 10B), multiple cutter brackets (9), multiple cutters (7), multiple springs (8), a linkage, an activating member (3) and a handle (1, 1 C). The base (10, 10B) has two ends. The cutter brackets (9) are mounted on the base (10, 10B). The cutters (7) are mounted slidably through the cutter brackets (9). The linkage connects pivotally to one end of the base (10, 10B). The activating member (3) connects pivotally to the linkage. The handle (1, 1C) connects pivotally to the other end of the base (10,10B) and selectively pivots the linkage down. With the linkage and the activating member (3), the hole punch is effort-saving.</p> |
