Abstract

A fixing structure includes a first supporting disc, a second supporting disc, and an electronic connector. The first supporting disc defines a first through hole. The second supporting disc is movably connected to the first supporting disc. The second supporting disc defines a first receiving groove for receiving a voice coil motor having a lens. The second supporting disc further defines a second through hole passing through a bottom of the first receiving groove. The first through hole and the second through hole are coaxial. The electronic connector is disposed on the second supporting disc, and can be electrically connected to the voice coil motor and an external power supply.
