  • Patent number: 11497173
    Abstract: A garden shears has a first cutting member, a second cutting member and a protecting member. The first cutting member and the second cutting member are combined adjacent to each other, and the first cutting member and the second cutting member respectively have a blade portion facing the blade portion of the other cutting member. The blades of the first cutting member and the second cutting member are used for opposite positioning cutting, instead of staggered cutting after closing, which can avoid the formation of two different cut surfaces on both sides of the branches. The protecting member has a securing aperture and an arced slot, and the securing aperture is a polygonal aperture with multiple engaging edges.
