Abstract

The invention discloses a hole puncher, which comprises a fixed handle, a movable handle, a crank, a hole punching shaft, a shaft chuck, a spring, a conical head fixer, conical heads, a support plate and a movable baffle plate. According to the hole puncher, punching tasks can be completed easily by using hand force when hole punching files are not too thick; and if the hole punching files are thicker, and hand force is insufficient, the crank can be rotated easily for assisting in finishing hole punching. In the hole puncher, a plurality of kinds of conical heads are available for replacing, so that the requirement of punching of different holes can be met, and the manual punching force can be reduced by replacing the conical heads. The hole puncher disclosed by the invention has the advantages of simple structure, low manufacturing cost, saving in punching force, higher punching efficiency and capability of punching a plurality of holes as required.
