The invention provides a semi-trailer tractor steering device, belongs to the technical field of vehicle traction and aims to solve a technical problem that a semi-trailer vehicle in an existing semi-trailer tractor cannot follow up and steer within a reasonable angle range. The semi-trailer tractor steering device comprises a lower tray connected with a tractor and an upper tray connected with a semi-trailer vehicle, wherein the lower tray and the upper tray are connected and can oppositely rotate; a steering mechanism capable of rotating and connected with semi-trailer vehicle wheels is arranged between the lower tray and the upper tray; when the lower tray steers within a preset angle, the steering mechanism is connected with the lower tray and rotates along with the lower tray; when the lower tray rotates to a position out of the preset angle, the steering mechanism is separated from the lower tray and connected with the upper tray; a follow-up steering angle of the semi-trailer vehicle wheels is controlled with a reasonable angle scope, and the semi-trailer vehicle wheels can steer in a follow-up manner, and do not steer excessively, so that the scope of a blind area is reduced, the accident occurrence probability is reduced, and the semi-trailer vehicle is prevented from drifting or laterally turning over.
