Abstract
The shear of the present invention includes a clipper, an elastic element and a holding portion. A first cutter of the clipper forms a pressing face, and a second cutter of the clipper forms a leaning face corresponding to the pressing face. When the clipper splays to a maximum angle, the pressing face and the leaning face touch each other, and the elastic force is accepted by the leaning face. Because the first cutter and the second cutter are made of a same material and the hardness of the first and the second cutters is the same, the contact faces of the cutters are not abraded after several times touching. Thereby, the shear of the present invention is much more durable.
Claims8
A shear, including:
- a clipper, including a first cutter and a second cutter, each of the first and the second cutters being in a bending form and including a blade, a pivot portion, and a connecting portion, each pivot portion being located between the blade and the connecting portion, the pivot portions connecting to each other to enable the first and the second cutters to splay apart or join together, the blades overlapping and scissoring when the blades join together, the pivot portion of the first cutter having a pressing face, an edge of the blade of the second cutter has a leaning face, the first cutter and the second cutter being unable to splay apart and the blades overlapping and contacting each other when the pressing face touches the leaning face;
- an elastic element, the elastic element enabling the first cutter and the second cutter to tend to splay to a maximum angle;
- a holding portion, including a first holder and a second holder connecting to each other pivotally, the first holder and the second holder being able to splay apart or join together, the first holder connecting to the connecting portion of the first cutter, the second holder connecting to the connecting portion of the second cutter, the holding portion and the clipper splay or join simultaneously.
