Then, the driven pulley of the oil pump is connected to the first pulley 21 via a belt, and the driven pulley of the water pump is connected to the second pulley 22 via a belt. In use, the motor power is turned on, and the motor drives the bushing 1 to rotate continuously through the output shaft. The bushing 1 drives the first pulley 21 to rotate continuously, and the first pulley 21 transmits power to the driven pulley of the oil pump via a belt, ensuring the oil pump is always in operation. When the water pump needs to work, the power supply to the electromagnetic clutch 3 is turned on, the electromagnetic clutch 3 works, the coil 37 is energized and attracts the armature 35, the armature 35 moves and drives the sliding toothed disc 33 to slide along the fixed toothed disc 32. Finally, the fourth tooth of the sliding toothed disc 33 meshes with the third tooth of the flat toothed disc 34, so that the flat toothed disc 34 drives the sliding toothed disc 33 to rotate continuously. The sliding toothed disc 33 meshes with the first tooth of the fixed toothed disc 32 through the second tooth, so that the sliding toothed disc 33 drives the fixed toothed disc 32 to rotate continuously. The fixed toothed disc 32 drives the second pulley 22 to rotate continuously. The second pulley 22 transmits power to the driven wheel of the water pump through the belt, so that the water pump is in working condition.
