Turn to coupling mechanism with universal joint

The utility model discloses a turn to coupling mechanism with universal joint, including two joint bearing that act on pneumatic cylinders and locate its tip, still including the universal joint of locating two effect pneumatic cylinder tip, the connected mode of joint bearing, universal joint and two effect pneumatic cylinders has two kinds, firstly connection universal joint, stiff end connection joint bearing are held in stretching out of two effect pneumatic cylinders, or joint bearing, stiff end connection universal joint are connected to the end that stretches out of two effect pneumaticcylinders. Originally, it can bear the each side to great load to turn to coupling mechanism, also can make tilting motion's joint bearing at a constant angle degree within range, combine high transmission efficiency, the universal joint that turns to in a flexible way, it effectively transmits to satisfy power, guaranteed that the driving turns to the fore -and -after and coordinates in step, realize nimble turning to,
