[0070] This completes the use process of the connection structure of the 3D stereo camera of the preferred embodiment. The structure of the present invention is compact and easy to use. The 3D stereo camera is connected to the viewfinder 8 by a snap-fit ​​connection between the camera body 5 and the camera body 5, which is easy to carry and improves the practicality of the structure. When shooting directly, the plane image shot can be directly viewed through the camera body 5; the viewfinder 8 is installed by snap-fitting to facilitate viewing of the three-dimensional image effect, which improves the practicality of the structure.

[0071] Combination Figure 6 and Figure 7 The 3D stereo camera in this embodiment is provided with a driving structure; the viewfinder can be moved away, and the viewfinder allows the camera body to perform normal framing; at the same time, the viewfinder triggers the Hall switch of the camera body after approaching the camera body, and the viewfinder can also view the image effect through the lens device of the device for the first time.

[0072] The driving structure is used to convert the first plane image displayed by the camera body 5 into a relative left display image and a right display image, so as to facilitate the viewfinder 8 to view.
