Abstract
A labor-saving hole punch includes a base, an operating unit, a linking unit, and a punching unit. The operating unit is pivotally mounted to the base for rotation relative to the base. The linking unit has two ends, one of which is connected to the operating unit and the other is pivotally mounted to the base. The punching unit is mounted to the base and connected to the linking unit. The operating unit and the linking unit are pivotally mounted to the same side of the base. The punching unit is connected to a midsection of the linking unit. The linking unit is actuated by the operating unit to drive the punching unit to punch. With the cooperation among the operating unit, the linking unit, and the punching unit, the hole punch has a long punch stroke to punch a larger number of paper sheets and to be labor-saving.
