The invention provides a buffering shock absorption steering wheel with an angle capable of being changed in a dangerous situation. According to the buffering shock absorption steering wheel, impact loads can be absorbed when a vehicle is urgently braked at a high speed and a collision happens; and meanwhile the angle of the steering wheel is changed, so that the contact area of the steering wheel and the body of a driver is increased, and the safety of the driver is protected. When the vehicle is braked at a low speed and jolts on a road surface, the hydraulic safety steering wheel can absorb part of the impact loads as well, the harm caused by vibration impact to the driver can be relieved, the driving comfort of the driver is improved, and the smoothness and operation stability of the vehicle are improved. An upper piston cylinder and a lower piston cylinder of a steering shaft are connected through a spline so that the radial size can be reduced, and the large torque can be transmitted. By the adoption of the hydraulic safety steering wheel, the vibration impact on the steering shaft and a steering disc is absorbed through hydraulic oil small hole damping, and the safety of the driver is protected; and meanwhile the steering wheel is simple in structure, the manufacturing and assembling difficulty can be effectively reduced, and therefore the use cost is reduced.
