1. An actuator for rotating a mirror head of a rear view device of a motor vehicle about two axes relative to a base of the rear view device, the actuator comprising:
a gear assembly, comprising:
a fold gear configured to rotate the mirror head in a first direction and a second direction about a first axis, wherein the fold gear comprises a first opening in form of a first bore or a first through hole,
a tilt gear configured to rotate the mirror head in a third direction and a fourth direction about a second axis, wherein the tilt gear comprises a second opening in form of a second bore or a second thorough hole,
a spindle having a first end and a second end, and
a slide attached to the spindle via a channel,
wherein the second opening of the tilt gear receives the first end of the spindle and the first opening of the fold gear receives the second end of the spindle;
a housing enclosing the gear assembly, wherein the housing is configured to rotate with the mirror head in the first direction, the second direction, the third direction, and the fourth direction; and
a shaft configured to be fixed on the base and configured to remain stationary, wherein the shaft provides at least one end stop configured to define a maximum rotation of the mirror head in the first direction and in the second direction.
