1. A propeller control mechanism comprising:
a center comprising a central axis, wherein the central axis serves as the center's rotary axis;
a first group mechanically connected to the center, comprising a first component of the first group, a second component of the first group, and a third component of the first group;
the first component of the first group is mechanically connected to the center, and is able to rotate relative to the center about a first axis of the first group;
the second component of the first group is mechanically connected to the first component of the first group, and is able to rotate relative to the first component of the first group about a second axis of the first group; and
one end of the third component of the first group is mechanically connected to the second component of the first group, and the second component is able to rotate relative to the third component of the first group about a third axis of the first group; another end of the third component of the first group is mechanically connected to the center, and is able to rotate relative to the center about a fourth axis of the first group;
wherein the first axis of the first group, the second axis of the first group, the third axis of the first group, and the fourth axis of the first group meet at a same point; and
a second group is mechanically connected to the center, the second group comprising a first component of the second group, a second component of the second group, and a third component of the second group;
the first component of the second group is mechanically connected to the center, and is able to rotate relative to the center about a first axis of the second group;
the second component of the second group is mechanically connected to the first component of the second group, and is able to rotate relative to the first component of the second group about a second axis of the second group; and
one end of the third component of the second group is mechanically connected to the second component of the second group, and the second component is able to rotate relative to the third component of the second group about a third axis of the second group; another end of the third component of the second group is mechanically connected to the center, and is able to rotate relative to the center about a fourth axis of the second group;
wherein the first axis of the second group, the second axis of the second group, the third axis of the second group, and the fourth axis of the second group meet at a same point.
