Abstract

The invention provides a mono-lever adjusting steering column, comprising a steering shaft (13), a transmission shaft (14) and an adjusting handle (9). The monolever adjusting steering column is characterized by also comprising a first locking mechanism and a second locking mechanism which are matched with and connected on the steering shaft (13). The first locking mechanism can be opened by the clockwise rotation of the adjusting handle (9), when the steering shaft (13) swings back and forth to finish the adjustment, the first locking mechanism and the adjusting handle (9) are driven by a first pullback spring (4) to reset; the second locking mechanism can be opened by the counterclockwise rotation of the adjusting handle (9), when the steering shaft (13) moves up and down to finish the adjustment, the second locking mechanism and the adjusting handle (9) are driven by a second pullback spring (6) to reset. Therefore, one four-link mechanism is utilized to drive the loose or the tightness of a pawl or a four head bolt so as to realize the adjustment of the steering column in transverse and longitudinal ranges; the mono-lever adjusting steering column has simple structure, convenient operation, safety and reliability and comparatively wider range of adjustment and ensures that the adjustment of the steering column in the driver zone becomes more humanized.
