| 摘要 |
This invention describes a hand operated, end cutting, sheet metal shear that makes cuts perpendicular to the axis of the tool handle. The shearing surfaces consist of a moving shear blade with a fixed rake angle and shear angle, cutting along a blunt anvil. The shear blade is pivotally mounted to the tool body and actuated by a toggle linkage and a movable handle. A stroke adjustment screw is incorporated into the fixed handle. The blade passes along the fixed anvil in response to squeezing the handles. The blade is angled so that the shearing action takes place sequentially along the anvil edge. The end cutting sheet metal tool is used to produce cuts at an angle to cuts made with sheet metal cutting tools.
