Description

[0002] The hand-crank wrench is in the shape of a "Z". One end of the hand-crank wrench is connected to a sleeve and a handle is installed at the other end. The internal shape of the sleeve is the same as the shape of the nut. The sleeve is put on the nut, and the other end is held to rotate the handle. The hand-crank handle removes or installs the nut. The principle of the hand-crank handle is a labor-saving lever. During the production process, the workpiece needs to be bent by a bending device. The existing bending device needs to be bent twice to form, and the workpiece position needs to be placed multiple times during the bending process. The bending part needs to return to its original position after bending before the next bending can be performed. At the same time, the bending device will stop working when the workpiece is placed, which increases the bending time of the workpiece, thereby reducing the production efficiency of the bending device. For this reason, a bending device that can speed up the bending efficiency is proposed. Summary of the Invention
