The invention relates to the technical field of power takeoff devices, in particular to a power takeoff device driving circuit structure. Comprising a gearbox controller; the power takeoff switch is controllably connected between the first input end of the gearbox controller and a power supply voltage; the first end of a coil of the first relay is grounded, and the second end of the coil of the first relay is controllably connected with the power supply voltage through the power takeoff switch; the first end of a coil of the second relay is connected with the output end of the gearbox controller, and the second end of the coil of the second relay is connected with the power supply voltage; and the power takeoff actuator is connected with the output end of the driving valve body. The power takeoff driving circuit structure is optimized by additionally arranging the relay, current intervention between the power takeoff switch and the control valve body is avoided, and the service life of the power takeoff switch is prolonged.
