The invention discloses a connecting mechanism for a steering gear and a rotary tube. The connecting mechanism comprises a steering gear oil outlet arranged on a steering gear valve body, a power steering oil tube connected with the steering gear oil outlet, and further comprises a connecting tube, wherein the power steering oil tube is connected with the steering gear oil outlet by virtue of the connecting tube; the connecting tube is a two-step step tube with a shaft diameter increasing from bottom to top; the connecting tube comprises a bottom stretching tube and a threaded tube connected with the stretching tube; a hexagonal nut is arranged at the top end of the threaded tube in a sleeving mode; the inner wall and the outer wall of the threaded tube are threaded structures; the steering gear oil outlet is a step hole matched with the two-step step tube, and inner threads are processed on the inner wall of a large hole; and outer threads are processed at the connecting end of the power steering oil tube. According to the scheme, the connecting tube is adopted, so that only is the connecting tube required to replace while the inner threads of the connecting nut are damaged in a repeated dismounting process of the steering gear valve body and the steering gear oil outlet, and the whole steering gear is not replaced.
