[0030] In addition, if the terms "first", "second" and the like are used herein, they are merely used to distinguish one entity from another, and do not imply or suggest relative importance.

[0031] As disclosed in the background art, the existing camera needs to be connected with other functional modules for use, and needs to be frequently replaced to cope with different shooting scenes. The connection between the camera and the functional module is generally through a buckle. The buckle connection has the following disadvantages: 1. The buckle has low positioning accuracy; 2. The buckle has a large size; 3. The buckle surface is plated with chromium, and the color is silver white, which does not match the black color of the camera, and the appearance is not integrated.

[0032] In addition, the existing camera generally has an opening for loading a filter or other functional structure at the connection. The opening at the connection is generally covered with a rubber cover for light shielding, and the rubber cover light shielding has the following disadvantages: 1. The rubber cover will hang on the camera when in use, and the overall appearance is redundant and bulky; 2. The rubber cover and the camera are matched, and there is a certain color difference in appearance due to different materials; 3. The rubber cover on the market is generally circular, and other shapes of rubber cover generally need to be customized, and the mold cost is high.

[0033] To solve the above problems, the embodiments of the present application provide a new camera and a full-spectrum main body. The specific structure and connection principle of the camera and the full-spectrum main body are introduced in detail below. It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

Each snap fastener 130 corresponds to one of these slots, thus securing the functional module 200 to the cover plate 120 and completing the assembly of the main unit. This embodiment uses multiple snap fasteners 130 to lock the functional module 200. The snap fasteners 130 protrude from the cover plate 120, locking the functional module 200 from the inside out, achieving better positioning accuracy. Furthermore, the snap fasteners 130 are located on the cover plate 120, inside the functional module 200, eliminating the need for an external snap-fit ​​structure, resulting in a smaller overall size and better aesthetic consistency. This embodiment uses two snap fasteners 130 as an example for detailed explanation.

[0039] In other preferred embodiments of this utility model, the first camera module may also be a functional module 200, and the second camera module may also include a camera body 110.
