Hydraulic connection mechanism that turns to in a flexible way

The utility model discloses a hydraulic connection mechanism that turns to in a flexible way, hydraulic connection mechanism that turns to in a flexible way, including two effect pneumatic cylinders,first universal joint is connected to the end that stretches out of two effect pneumatic cylinders, first universal joint is used for control to turn to, the second universal joint is connected to thestiff end of two effect pneumatic cylinders, the second universal joint is used for the transmission to turn to. This coupling mechanism all connects the universal joint at the both ends of two effect pneumatic cylinders, it all connects the structure that the light nodal axisn held to change current both ends, it effectively transmits to satisfy power, the adaptation turns to and drives a vehicle when operation produced upper and lower angle that causes of beating and changes, it coordinates in step to have guaranteed the front and back power output that traffic control turned to, the effectual flexibility that has r
