The first hole 211 allows the first shaft 351 to pass through to connect with the first knob 5 , and the second hole 212 allows the second shaft 352 to pass through to connect with the second knob 6 .

[0112] In some embodiments, the main body plate 222 is provided with a third hole 2221 corresponding to the first hole 211 for the first shaft 351 to pass through, thereby preventing the first shaft 351 from being skewed; the main body plate 222 is provided with a fourth hole 2222 corresponding to the second hole 212 for the second shaft 352 to pass through, thereby preventing the first shaft 351 from being skewed.

[0113] Ginseng Figure 3 and Fig.24 The camera 100 includes a baffle 24 fixed to the back cover 21 to shield the first operating member and the second operating member, thereby preventing accidental adjustment of the first operating member and the second operating member. When the first operating member and the second operating member need to be adjusted, the baffle 24 can be removed.

[0114] In some embodiments, the baffle 24 and the back cover 21 are fixed by a limit screw 241 to facilitate assembly and disassembly of the baffle 24. Optionally, the baffle 24 and the back cover 21 can also be fixed by a snap-fit ​​or threaded connection.

[0115] Ginseng Fig.25 and Fig.26The front end of the housing 1 is bent, and the front end of the lens 32 is also bent to meet the needs of different scenes.

[0116] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
