Abstract: 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.
