A two-dimensional electro-hydraulic servo valve based on a dual-redundancy transmission mechanism, including a valve body, a valve spool inside the valve body, and a valve sleeve on an outside of the valve spool. A low-pressure chamber is disposed between the valve spool and the valve sleeve; the valve body is connected to a servomotor through a transmission mechanism; the transmission mechanism includes a spool fork and a motor toggle, and each end of the motor toggle is connected to a spherical connector; the spherical connector is rotatable with a centerline of a connection end of the motor toggle as an axis; each end of the spool fork is slidably connected to a corresponding spherical connector; a middle part of the spool fork is connected to the valve spool, and a middle part of the motor toggle is connected to a rotor of the servomotor.
