Abstract
A paper processing tool includes a base having a receiving area for selectively receiving a sheet of paper. The tool further includes a first lever having a handle portion, the first lever being pivotable relative to the base about a first axis. An intermediate lever is pivotable relative to the base about a second axis in response to movement of the first lever. At least one cutting element is arranged along a cutting plane, the at least one cutting element being configured to selectively engage the sheet of paper. A drive lever is actuable by the intermediate lever to move the at least one cutting element relative to the base. The drive lever is pivotable relative to the base about a third axis parallel to the cutting plane.
Claims12
A paper processing tool comprising:
- a base having a receiving area for selectively receiving a sheet of paper;
- a first lever having a handle portion, the first lever being pivotable about a first axis that is fixed relative to the base;
- an intermediate lever being pivotable relative to the base about a second axis in response to movement of the first lever;
- at least one cutting element arranged along a cutting plane, the at least one cutting element being configured to selectively engage the sheet of paper;
- and
- a drive lever pivotable about a third axis that is fixed relative to the base, the third axis being parallel to the cutting plane,
- wherein pivoting of the first lever about the first axis drives the intermediate lever to pivot about the second axis, pivoting of the intermediate lever about the second axis drives the drive lever to pivot about the third axis, and pivoting of the drive lever about the third axis drives the at least one cutting element to move relative to the base, and
- wherein the first axis and the second axis are substantially parallel, and the third axis is substantially perpendicular to the first axis and the second axis.
