This invention relates to the field of commercial vehicle steering column technology, specifically disclosing an adjustment structure for a commercial vehicle steering column. The structure utilizes an angle adjustment component to drive the steering column body to rotate, and a sliding fit structure between a sliding seat and a sliding groove allows the steering column body to achieve a large rotational stroke under the drive of the angle adjustment component. Specifically, the angle adjustment component employs a lead screw drive structure. A first driving member drives a first lead screw to extend and retract, thereby pushing the steering column body to rotate around its hinge point. Because the first lead screw has a long extension and retraction stroke, and the lever arm between the hinge point of the steering column body and the connection point of the angle adjustment component can be optimized to a shorter distance, a small extension and retraction of the lead screw can be converted into a large angle change. Simultaneously, the longer first lead screw stroke further amplifies the angle adjustment range to adapt to different driving needs and driver maneuverability.
