Abstract: A combination binding and perforation assembly, which includes a base portion, binding rings, perforating rods, guiding plates, a wall portion, a perforation slot, and a lever. The binding rings protrude from the base portion. Each perforating rod is coupled with a respective binding ring via a respective connector. The perforation slot is defined by a gap between the guiding plates and wall portion, which is disposed at an edge of the base portion. The lever is coupled with the binding rings, and can be manually raised and lowered. When the lever is raised, the binding rings open and the perforating rods advance toward the perforation slot to perforate at least one paper sheet inserted in the perforation slot. When the lever is lowered, the binding rings close and the perforating rods retract from the perforation slot. The perforated sheet can then be inserted into the binding rings through the perforations.
