In the first transmission mechanism 4 , by setting the first turbine 411 and the worm assembly 41 to connect with the first power mechanism 2 , the power rotating around the rotating shaft on the first power mechanism 2 is effectively converted into the first turbine 411 and the worm assembly 41 The rotational power perpendicular to the rotating shaft is then transmitted to the rotational power of the first gear shaft 42 through gear meshing transmission, so as to make the angle from the rotational power generated on the first power mechanism 2 to the rotational power on the first gear shaft 42 A 90° change has occurred.

Similarly, the angle of the rotational power on the second power mechanism 3 and the second transmission mechanism 5 has also changed by 90°, so that the power generated at both ends of the box body 1 is finally output from both sides of the box body 1, realizing Two outputs of the geared motor.
