The invention discloses a two-stage gear transmission steering mechanism. The two-stage gear transmission steering mechanism comprises a universal joint, a front axle assembly, a transitional chain wheel bearing seat assembly and a front wheel frame assembly. A steering wheel is arranged at the upper end of the universal joint, and a first small chain wheel is arranged at the lower end of the universal joint. The transitional chain wheel bearing seat assembly is provided with a transitional chain wheel shaft, and the transitional chain wheel shaft is provided with a transitional chain wheel and a second small chain wheel sequentially from top to bottom. A second shaft is arranged at the upper end of the front wheel frame assembly, and a U-shaped block with a downward opening is arranged at the lower end of the front wheel frame assembly. A large chain wheel is arranged at the upper portion of the second shaft. The front wheel frame assembly is composed of a fixing block and a transmission shaft, and the fixing block is located in the groove of the U-shaped block. The first small chain wheel and the transitional chain wheel are connected through a first chain, and the second small chain wheel and the large chain wheel are connected through a second chain. The two sides of the transmission shaft are each provided with a steering wheel. The steering wheels rotate to indirectly drive the large chain wheel to rotate, so that the steering wheels are driven to steer, the transmission ratio is increased, and the steering control force of an operator is reduced.
