A step-separating shearing tool includes a first handle and a second handle. A first blade portion is connected to the first handle, and a second blade portion, which includes an L-shaped slot, is hinge-connected to the first blade portion and to the first handle. A rocker arm connects the second handle and the first blade portion. The step-separating shearing tool also includes an automatic step-separating mechanism. This mechanism includes: a double-oscillating rod, which is hinge-connected to the rocker arm; a slider on the double oscillating rod, which is received in the L-shaped slot of the second blade portion; and a torsion spring connected between the rocker arm and the double oscillating rod. When the shearing tool is used in a cutting operation for cutting items having a relatively small diameter, the slider is located in a short slot portion of the L-shaped slot during the entire cutting operation. However, when the shearing tool is used in a cutting operation for cutting items having a relatively large diameter, the slider is located in a long slot portion of the L-shaped slot during a first part of the cutting operation, to partially cut through the item being cut, and then the slider is moved to the short slot portion of the L-shaped slot during a second part of the cutting operation. |
