[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Embodiment one

[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme: a whole machine camera near focus SFR test equipment, including SFR test equipment body 1, the front end surface of SFR test equipment body 1 is connected with control panel 2 and open-close door 3, open-close door 3 is located at the bottom end of control panel 2 and surface installation has transparent glass, the front end surface of SFR test equipment body 1 one side is inserted with support plate 4, the front end surface of SFR test equipment body 1 is installed with fixed block 5, the inside of fixed block 5 is provided with sliding groove 6, the inside of sliding groove 6 is connected with sliding block 8, sliding groove 6 is installed with spring 7 in the inside, the front end surface of sliding block 8 is connected with limiting plate 9, the side wall of support plate 4 is provided with limiting groove 10.

[0022] In the preferred embodiment, the sliding block 8 and the sliding groove 6 are adapted to form a "convex" shape, and the limiting plate 9 is connected to the sliding block 8 and the sliding groove 6 through the sliding connection.

[0023] In the preferred embodiment, the sliding block 8 is connected to the sliding groove 6 through the spring 7 to form an elastic expansion connection.

[0024] In the preferred embodiment, the support plate 4 is connected to the SFR test equipment body 1 through the limiting plate 9 to form a detachable fixed connection.

[0025] In the preferred embodiment, the limiting plate 9 is connected to the limiting groove 10 through the clamping connection.

[0026] In the embodiment, first, the SFR test equipment belongs to the existing mature technology, and its model is CCM-SFR04 camera SFR test machine. The equipment can be used for SFR test of whole machine camera near focus and far focus. Then, the test equipment has no obvious connection with the technical features described in the text, and therefore the text will not be described in detail.

[0027] In addition, when the whole machine camera is tested for close focus, the opening and closing door 3 is opened and the whole machine camera is placed inside the SFR test equipment body 1. During the test, the operator manually pushes the limiting plate 9 to move, so that it is moved away from the front end of the supporting plate 4, and then the supporting plate 4 is pulled out. Then, the limiting plate 9 is released, which will drive the sliding block 8 to slide in the sliding groove 6 under the action of the spring 7, and automatically reset. When the supporting plate 4 is pulled out and the limiting plate 9 is reset, the limiting plate 9 will be clamped into the limiting groove 10, thereby fixing the supporting plate 4.

[0028] During this period, the operator can use the test gap to manually take a new whole machine camera to be tested and place it on the supporting plate 4. Then, after the test is completed, the quick replacement can be performed. The lack of placement conditions is avoided, and the manual taking of the whole machine camera to be tested is also not convenient for placement. Only after the test is completed, the operator can manually take the whole machine camera to be tested again. The time difference is generated.
