1. A reflection module capable of image stabilization, comprising:
a reflecting element, having a reflecting surface, wherein the reflecting element is configured to fold an optical path of incident light;
a rotatable holder, wherein the reflecting element is disposed on the rotatable holder;
a fixed base, connected to the rotatable holder via an elastic element;
a spherical supporting structure, disposed between the rotatable holder and the fixed base;
an auxiliary supporting structure, disposed on at least one of the rotatable holder and the fixed base, wherein the auxiliary supporting structure corresponds to the spherical supporting structure; and
an image stabilizing actuator, wherein at least a part of the image stabilizing actuator is disposed on the rotatable holder, and the image stabilizing actuator is configured to drive the rotatable holder to rotate by taking the spherical supporting structure as a rotation center;
wherein the spherical supporting structure comprises two balls, and the spherical supporting structure has at least three contact points with the auxiliary supporting structure.
