1. A differential power horizontal-vertical switchable actuator module comprising:
an actuator which rotates a horizontal drive shaft formed in the horizontal direction as a whole,
the actuator having:
a case,
a motor installed inside the case and configured to rotate a motor rotation shaft, and
a differential gear set installed on one end of the motor rotation shaft;
a first gearbox which is connected to one side end of the horizontal drive shaft and transfers rotational power from the one side of the horizontal drive shaft by switching the direction to a first vertical rotation shaft that is in the vertical direction as a whole; and
a second gearbox which is connected to the other side end of the horizontal drive shaft and transfers rotational power from the other side of the horizontal drive shaft by switching the direction to a second vertical rotation shaft that is in the vertical direction as a whole,
wherein the differential gear set is configured to allow a first rotation speed of the first vertical rotation shaft of the first gearbox and a second rotation speed of the second vertical rotation shaft of the second gearbox to rotate at different speeds.
