As shown in fig. 1 and 2, a steering mechanism for unmanned ship comprises:
the tail end of the power input shaft 9 is sleeved with a driving bevel gear 11;
the first gear shaft 5 and the second gear shaft 6 which are coaxially arranged are symmetrically arranged by taking the power input shaft 9 as a center and are perpendicular to the power input shaft 9, and clamping grooves are formed in the first gear shaft 5 and the second gear shaft 6;
the first bevel gear 1 and the second bevel gear 2 are respectively arranged at one ends of the first gear shaft 5 and the second gear shaft 6, which are close to the power input shaft 9;
the first sliding gear 3 and the second sliding gear 4 are respectively sleeved on the first gear shaft 5 and the second gear shaft 6;
a power output shaft 10 parallel to the first gear shaft 5 and the second gear shaft 6;
the first straight gear 7 and the second straight gear 8 are sleeved on the power output shaft 10;
two ends of the reversing rod 12 are respectively sleeved on the clamping grooves of the first gear shaft 5 and the second gear shaft 6, and when the reversing rod slides along the axial direction of the power output shaft 10, the reversing rod drives the first gear shaft 5 and the second gear shaft 6 to slide along the axial direction of the power output shaft 10, so that the driving bevel gear 11 can be selectively meshed with the first bevel gear 1 and the second bevel gear 2;
