The utility model belongs to the construction material transportation technical field discloses a handling trolley, including support subassembly and walking structure, wherein, support subassembly includes support beam, first support piece and second support piece, when the piece to be handled is placed in handling trolley, support beam can support the piece to be handled, the first side of the piece to be handled can be attached to first support piece, the second side can be attached to second support piece, the contact area of the piece to be handled and handling trolley is larger, handling trolley is not prone to the phenomenon of local stress concentration, and the safety of the handling process of the piece to be handled is higher. First support piece and second support piece can limit the displacement of the piece to be handled along the length direction of support beam, and the transportation stability of the piece to be handled is improved. Walking structure is rotationally arranged below support beam, which facilitates workers to transport the piece to be handled by pushing the handling trolley, saves labor cost compared with manual handling by many workers, reduces the labor intensity of workers, and improves the handling efficiency.

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.
