In recent years, with the development of the technology industry, electronic devices, such as smart phones or tablet computers, have frequently appeared in daily life. In addition to their own functions, these electronic devices are usually equipped with additional functional components to have additional functions. For example, an electronic device may be configured with components such as a camera.

At present, the electronic device usually fixes the upper and lower sides of the camera through a fixing structure, and the surrounding side is limited by a chassis structure (chassis). However, when the electronic device is impacted, the optical axis of the camera will deviate along with the deformation of these fixed structures. With the advancement of technology, some electronic devices have a dual-camera design. Since an electronic device with dual cameras uses two cameras for triangulation to calculate the distance between the object and the camera, this type of electronic device has higher requirements for the parallelism of the optical axis. If the optical axis shifts, the calculated The resulting distance error will also be larger, and the photographic effect that meets the requirements cannot be obtained.
