1. A camera module, comprising:
a base;
a lens module, having an optical axis, and the lens module being disposed on the base;
a reflection module, comprising a reflective element, the reflective element being disposed on the base, and the reflective element located on an object side of the lens module;
a longitudinal guiding bar, disposed between the base and the lens module, and the longitudinal guiding bar extending in a first direction parallel to the optical axis;
a transverse guiding bar, disposed between the base and the lens module, and the transverse guiding bar extending in a second direction perpendicular to the optical axis; and
a shaft guiding bar, disposed between the base and the reflection module, and the shaft guiding bar extending in the second direction;
wherein the lens module is movable along the longitudinal guiding bar and the transverse guiding bar, respectively, and the reflective element is rotatable by taking the shaft guiding bar as a rotation axis;
wherein the camera module further comprises a movable frame disposed between the longitudinal guiding bar and the transverse guiding bar, and the movable frame is movable along one of the longitudinal guiding bar and the transverse guiding bar.
 
17. A camera module, comprising:
a base;
a lens module, having an optical axis, and the lens module being disposed on the base;
a reflection module, comprising a reflective element, the reflective element being disposed on the base, and the reflective element located on an object side of the lens module;
a transverse guiding bar, disposed between the base and the lens module, and the transverse guiding bar extending in a direction perpendicular to the optical axis; and
a shaft guiding bar, disposed between the base and the reflection module, and the shaft guiding bar extending in the direction perpendicular to the optical axis;
wherein the lens module is movable along the transverse guiding bar, and the reflective element is rotatable by taking the shaft guiding bar as a rotation axis;
wherein the camera module further comprises a preload element connected to the base and the reflection module, the preload element is configured to provide a preload force to the reflection module in a direction towards the base, such that the shaft guiding bar located between the base and the reflection module supports the reflection module;
wherein the camera module further comprises a damping element disposed between the preload element and the base, and the damping element is directly in contact with the preload element and the base.
