A multifunctional engineering accessory with 6-bar mechanism comprising: a 6-link rod clamping device, a shear-fork separation device, a shearing device and locking device. Motion and lock of the 6-link rod group are implemented through a swing hydraulic cylinder of the 6-link rod clamping device to implement extending and withdrawing processes of a clamping paw. The shear-fork separation device can separate an accessory holder to meet the lateral dimension requirement of the multifunctional accessory. The shearing device can implement shearing and crushing function of multifunctional accessory, and the motion location of the accessory holder is confirmed by locking device while at the same time it sustains counterforce generated when the multifunctional accessory is working. The hydraulic ram is the power supply of the whole device. The present disclosure combines shearing, crushing and clamping on one accessory, and the structure design is a novelty, the driven pattern is reasonable, and the manufacturing technology is simple and easy to operate. The device can implement the crushing and moving processes of ruins better, while at the same time improving the economic efficiency.

The present disclosure provides a reversible cutting tool to cut a material such as sheet metal on a press brake. The reversible cutting tool is further comprised of a handle portion to grip and move the cutting tool, wheels to allow the cutting tool to slide along the press brake, a blade portion to cut the material, and an adjustable cutting mechanism. The adjustable cutting mechanism allows the reversible cutting tool to pivot and cut the material in two different directions, and also allows the cutting tool to be set in a third storage position. In a preferred embodiment, the adjustable cutting mechanism is comprised of a channel on an underside of the cutting portion, the channel configured to receive a plunger, the plunger to slide between two opposed cutting positions and a storage position.
