Abstract
A stapler includes a base, a cover put movably on the base, a feeding device for feeding staples, and a bending and cutting device provided between the base and the cover for bending and cutting the legs of each staple. The cutting device includes a seat provided on the base and a housing attached to the cover. The seat includes two wedges formed thereon and a pusher formed thereon. A stationary cutting element is provided in the housing. Two movable cutting elements are provided movably in the housing and on the two wedges so that they are moved towards the stationary cutting element in order to cut the legs of each staple as they are moved towards the seat together with the housing. A spring is put between the movable cutting elements in a tendency to push the movable cutting elements from the stationary cutting element. Two bending elements are provided movably and pivotally in the housing above the movable cutting elements so that they are pushed by the pusher in order to bend the legs of each staple after the stationary cutting element and the movable cutting elements cut the legs of each staple.
