Abstract
A paper punch has a base, two cutters, two articulated linkages and a lever. The base has a top, an open bottom, a cavity, two punch holes and two brackets. The punch holes are defined through the top. The brackets are mounted on the top and each bracket has two guide slots. The cutters are slidably mounted respectively in the brackets and each cutter has a blade. The articulated linkages are pivotally mounted respectively on the brackets and each has a lower link and an upper link. The lower link is mounted pivotally and slidably on a corresponding bracket. The upper link is mounted pivotally on a corresponding lower link. The lever is mounted pivotally on the brackets and is connected pivotally to the upper links of the articulated linkages. The articulated linkages allow a user to press the lever without strenuous effort when punching holes through paper sheets.
