In order to adapt to the driving of a car by people with different heights and arm lengths, the position of the steering wheel can be changed, namely the steering wheel is adjusted through the steering column. Usually, when the steering column has an angle or height adjusting function, the stroke adjustment is realized by forming a guide groove on an upper mounting bracket of the steering column.
In addition, different vehicle types are configured with different visual fields, so that the adjusting range of the steering column is different. If on a certain vehicle model of a new generation, the original steering column has too large adjusting stroke due to the change of the visual field, and the stroke range needs to be reduced to meet the requirement of a new vehicle model. Therefore, development and redevelopment of the steering column structure are required.
