Car and steering column locking device thereof

The utility model discloses a steering column locking device of car, including mount pad, straight -line motion mechanism and spring bolt, be provided with on the lateral wall of mount pad be used for with the work hole that the spring bolt closely cooperated, but set up straight -line motion mechanism linear motion in in the mount pad, just straight -line motion mechanism's bottom concatenation has the slope, the slope is inside to be provided with the slope grooved rail along its incline direction, the spring bolt top is provided with horizontal diagonal bar, horizontal diagonal bar set up in in the slope grooved rail to closely cooperate with it. The utility model discloses a normal pressure because the horizontal diagonal bar on the spring bolt closely cooperates with the slope grooved rail, will be exerted to horizontal diagonal bar to steering column locking device, straight -line motion mechanism in the motion, simultaneously because spring bolt and the unable horizontal movement of work hole cooperation, can only the elevating movement. Consequently, utilize the motion can control the steering column locking device at will. The utility model also discloses a car of including above -mentioned steering column locking device.
