As shown in fig. 10, the steering control circuit 5 includes a relay K1 and a relay K2, the control key group 2 further includes an output terminal L and an output terminal H, and the relay K1 and the relay K2 may be of a model LY3 NJ.
The relay K1 comprises a single-pole double-throw switch S8, a single-pole double-throw switch S9 and a single-pole double-throw switch S10, and the relay K2 comprises a single-pole double-throw switch S11, a single-pole double-throw switch S12 and a single-pole double-throw switch S13.
The common end of the single-pole double-throw switch S8 is connected with a voltage V-, a normally open contact is connected with a connecting end V2 of a voltage regulating motor P3, the common end of the single-pole double-throw switch S9 is connected with a voltage V +, the normally open contact is connected with the other connecting end V1 of a voltage regulating electrolysis P3, the common end of the single-pole double-throw switch S10 is electrically connected with an output end H of a regulating button group 2, the other end of the common end of the single-pole double-throw switch S10 is electrically connected with one end of a coil in a relay K.
The common terminal voltage V + of the single-pole double-throw switch S11 is connected with a connecting terminal V2 of the voltage regulating motor P3, the common terminal voltage V-of the single-pole double-throw switch S12 is connected with the normally open contact terminal V1 of the voltage regulating motor P3, the common terminal of the single-pole double-throw switch S13 is electrically connected with the output terminal L of the regulating key group 2, the other terminal of the single-pole double-throw switch S13 is electrically connected with one end of a coil in the relay K1, and the other end of the coil in the K1 is grounded.

When the normally open contact of the single-pole double-throw switch S10 is closed, the output end H is disconnected from the coil in the relay K2, and vice versa, so that the relay K1 and the relay K2 form an interlock, and the relay K1 and the relay K2 cannot be actuated simultaneously.
