ABSTRACT:
A compact hole punch for manually punching holes through sheet-like material to produce hole sets which enable the material to be mounted on multi-ring binders. The hole punch includes male and female plates, which in operation move convergently between an open position and a collapsed position and are retained in a parallel relative orientation by pivotally mounted support posts and a spring. The male plate carries a plurality of punch pegs while the female plate carries corresponding die openings through which the punch pegs penetrate to cut the holes in the material when the plates are pressed together. An adjustable slide member is removably mounted on the female plate for engagement with the posts to lock the hole punch in the collapsed position. The slide member also acts as an adjustable stop guide for positioning the material within the hole punch. A side edge of a pivotally mounted post engages in scissors-like fashion a juxtaposed edge portion of a plate thus providing a cutting functionality during the convergent movement of the plates.
