[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a fixed bracket for shooting 3D depth-of-field video with a single-lens reflex camera, comprising: a frame 1, a base 2, a camera 3, and a fixing mechanism 4;

[0018] The base 2 is set on the left and right sides of the inner cavity of the frame 1, and the two bases 2 are upside down. Cameras 3 are inserted into both sides of the frame 1, and the two cameras 3 are in contact. The fixing mechanism 4 is set between the camera 3 and the base 2.

[0019] As a preferred option, several through holes 5 are provided on both the left and right sides of the frame 1, and grooves 6 are provided on both the top and bottom sides of the frame 1. The through holes 5 are located at the sensor and button positions of the camera 3. By providing through holes 5 and grooves 6, the sensor and button positions of the camera 3 are exposed.

[0020] As a preferred embodiment, the fixing mechanism 4 further includes: a limiting block 41, a limiting groove 42, a stud 43, a plug rod 44, a plug hole 45, a spring 46, and a threaded hole 47.

[0021] In order to limit the camera 3, a limiting groove 42 is provided on the inner side of the base 2, and the front side of the limiting groove 42 is through. The limiting block 41 is inserted into the limiting groove 42. The stud 43 is fixedly set on one side of the limiting block 41 and screwed to one side of the camera 3. The inner cavity of the limiting groove 42 is provided with an insertion hole 45. An insertion rod 44 is inserted into the outer side of the limiting block 41 and is inserted into the inner cavity of the insertion hole 45. A spring 46 is fixedly set between the limiting block 41 and the insertion rod 44. Under the elastic force of the spring 46, the insertion rod 44 is inserted into the insertion hole 45, thereby limiting the camera 3.

[0022] As a preferred option, the insertion rod 44 is further shaped into a "T" shape to prevent the insertion rod 44 from disengaging from the bottom end of the limiting block 41.

[0023] As a preferred option, the frame 1 is further provided with threaded holes 47 on both the top and bottom sides and the left and right ends, through which the frame 1 can be connected and fixed to the tripod.

[0024] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0025] Before installing the camera 3 into the frame 1, rotate the stud 43 into one side of the camera 3. The stud 43 can fix the limiting block 41 to one side of the camera 3. Invert the two cameras 3 and push them into the frame 1 with the lenses facing the same fixed direction. Push the insertion rod 44 to one side so that the insertion rod 44 compresses the spring 46 and moves into the limiting block 41, so that the limiting block 41 is inserted into the limiting groove 42. Put the two cameras 3 close together into the frame 1. After the camera 3 is put in, under the elastic force of the spring 46, the insertion rod 44 is inserted into the insertion hole 45, which can limit the camera 3 and improve the stability of the camera 3 in the frame 1, so that the shooting is more convenient and stable. Even when moving, the misalignment will not change, making the picture more stable and less prone to technical failures. At the same time, it ensures the minimum spacing and minimum interpupillary distance.
