A slider 415 is slidably connected between the inner parts of every two opposite sliding grooves 414. A damper 416 is provided on the inner wall of each of the plurality of sliding grooves 414. A spring 417 is provided on the outer surface of each of the plurality of dampers 416. A moving rod 418 is fixed on the outer surface of one side of each of the plurality of sliders 415. A first iron block 419 is fixedly installed at one end of each of the plurality of moving rods 418. A photosensitive sensor 3 for detecting the light intensity is provided on the outer surface of the camera body 1. A movable rod 420 is fixed on the outer surface of the other side of each of the plurality of sliders 415. A second iron block 421 is fixed at one end of each of the plurality of movable rods 420. A plurality of mounting rods 422 are fixed on the outer surface of the threaded tube 401. A collar 423 is fixedly connected between one ends of the plurality of mounting rods 422. A second electromagnet 424 is provided on the outer surface of the collar 423. The inner wall of the threaded tube 401 is threadedly connected to the outer surface of the installation shaft 2. One end of the rotating shaft 408 is movably embedded on the outer surface of the driving gear 409 and meshed with the outer surface of the toothed ring 403. One ends of the plurality of dampers 416 are fixedly connected to the outer surfaces of the plurality of sliders 415 respectively. One ends of the plurality of springs 417 are fixedly connected to the outer surfaces of the plurality of sliders 415 respectively. The other ends of the plurality of springs 417 are fixedly connected to the inner walls of the sliding grooves 414 respectively. One ends of the plurality of moving rods 418 respectively movably penetrate to the outside of the plurality of mounting brackets 413. One ends of the plurality of movable rods 420 respectively movably penetrate to the outside of the plurality of mounting brackets 413.

[0035] In this embodiment, during the use of the camera, when it is necessary to use a CPL filter to adjust the quality of the captured image, first, the threaded tube 401 is sleeved on the surface of the mounting shaft 2, and the threaded tube 401 is rotated so that the threaded tube 401 is threadedly connected to the mounting shaft 2, thereby fixing the threaded tube 401 on the outer surface of the camera body 1, and further fixing the CPL filter body 412 on the outer surface of the camera body 1. During the use of the camera body 1, the photosensitive sensor 3 is turned on. Among them, the photosensitive sensor 3 includes light-sensitive materials, such as photodiodes or photoresistors. When light irradiates these sensitive materials, it will cause changes in the internal electronic state of the materials. Taking the photoresistor as an example, in a dark environment, its resistance value is relatively high, while when there is light irradiation, the photon energy excites the electrons inside the material, enhancing its conductivity and reducing the resistance value. By measuring the voltage or current change across the photoresistor, the change in ambient light intensity can be indirectly reflected. When the photosensitive sensor 3 detects that the ambient light is too high and it is necessary to increase the image saturation, first, the forward and reverse motor 407 is started to drive the rotating shaft 408 to rotate, and then drive the driving gear 409 to rotate. The driving gear 409 drives the toothed ring 403 to rotate. Among them, as Figure 4 shown, there is a raised circular ring on the inner wall of the toothed ring 403. The purpose is to facilitate the connection between the toothed ring 403 and the limiting groove 402, play a limiting role for the toothed ring 403 and also facilitate its rotation. Then, a plurality of first electromagnets 405 are electrically connected to an external power source to generate a magnetic field, so that a plurality of first iron blocks 419 move towards the direction of the plurality of first electromagnets 405 under the action of the magnetic force, thereby driving a plurality of moving rods 418 to move towards the direction of the first electromagnets 405, and further stretching a plurality of springs 417. Under the attraction of the magnetic force, when the toothed ring 403 rotates, it drives a plurality of first electromagnets 405 to rotate, and then drives the CPL filter body 412 to rotate. Among them, as Figure 6 shown, the cross-section of the rotating block 411 matches the internal cross-section of the rotating groove 410, both of which are T-shaped. The purpose is to limit the CPL filter body 412 and also facilitate its rotation. When the photosensitive sensor 3 detects that the quality of the image captured by the camera body 1 reaches the required quality, it transmits a signal to an external control device, and the forward and reverse motor 407 can be turned off through the external control device. On the contrary, when it is necessary to reduce the saturation of the captured image, the forward and reverse motor 407 is started in the reverse direction to drive the CPL filter body 412 to rotate in the reverse direction. Through the action of the automatic adjustment component 4, the CPL filter body 412 can automatically adjust the saturation of the camera according to the intensity of the external light. And because the photosensitive sensor 3 is sensitive to the intensity value of the external light, it can accurately rotate the CPL filter body 412 to the required position, thereby improving the quality of the image captured by the camera body 1, and solving the problem that the existing CPL filter in the prior art does not have an automatic adjustment function, reducing the practicability of the CPL polarizing filter.

[0036] Example Two

[0037] As Figure 1 and Figures 3-9 shown in and , a photosensitive sensor 3 for detecting the light intensity is provided on the outer surface of the camera body 1. On the outer surfaces of the other sides of the plurality of sliders 415, movable rods 420 are fixed. At one ends of the plurality of movable rods 420, second iron blocks 421 are fixed. On the outer surface of the threaded tube 401, a plurality of mounting rods 422 are fixed. Between one ends of the plurality of mounting rods 422, a collar 423 is fixedly connected. On the outer surface of the collar 423, a second electromagnet 424 is provided. The inner wall of the threaded tube 401 is threadedly connected to the outer surface of the mounting shaft 2. One end of the rotating shaft 408 is movably embedded in the outer surface of the driving gear 409 and meshed with the outer surface of the toothed ring 403. One ends of the plurality of dampers 416 are respectively fixedly connected to the outer surfaces of the plurality of sliders 415. One ends of the plurality of springs 417 are respectively fixedly connected to the outer surfaces of the plurality of sliders 415. The other ends of the plurality of springs 417 are respectively fixedly connected to the inner walls of the sliding grooves 414. One ends of the plurality of moving rods 418 respectively movably penetrate to the outside of the plurality of mounting frames 413. One ends of the plurality of movable rods 420 respectively movably penetrate to the outside of the plurality of mounting frames 413.

[0038] In this embodiment, since the camera body 1 is often used for external shooting and the external environment is changeable, when the CPL filter body 412 rotates to the required angle, because most of the forward and reverse motors 407 on the existing market do not have a self-locking function and the positioning effect is relatively poor. In order to prevent the position of the CPL filter body 412 from shifting due to external collisions and affecting the shooting effect, first, the plurality of first electromagnets 405 are disconnected from the external power supply, so that the plurality of first iron blocks 419 are no longer attracted by the external magnetic field and reset under the elastic action of the springs 417. Then, the second electromagnet 424 is electrically connected to the external power supply to generate a magnetic field, so that the plurality of second iron blocks 421 are affected by the magnetic force and move towards the second electromagnet 424, and thus are tightly connected to the second electromagnet 424, thereby fixing the plurality of second iron blocks 421 and fixing the CPL filter body 412, effectively preventing the problem that the position of the CPL polarizing filter shifts due to external collisions.

[0039] Example Three

[0040] As Figure 1 and Figure 10, a cleaning component 5 is arranged on the outer surface of the collar 423. The cleaning component 5 includes an auxiliary frame 501. The outer surface of the auxiliary frame 501 is fixedly connected to the outer surface of the collar 423. A driving motor 502 is arranged on one inner wall of the auxiliary frame 501. The output shaft of the driving motor 502 is fixedly connected to a connecting shaft 503. One end of the connecting shaft 503 is movably embedded in the other inner wall of the auxiliary frame 501. A bearing frame 504 is fixedly sleeved on the outer surface of the connecting shaft 503. A multi-stage electric telescopic rod 505 is arranged on the outer surface of the bearing frame 504.

[0041] In this embodiment, when the photosensitive sensor 3 detects dirt on the surface of the CPL filter body 412, first start the driving motor 502 to drive the connecting shaft 503 to rotate, and then drive the bearing frame 504 to rotate. At the same time, start the multi-stage electric telescopic rod 505 to make it stretch back and forth, drive the moving block 506 to move back and forth, and then drive the sponge block 507 to move back and forth. Through the rotation of the bearing frame 504, the sponge block 507 wipes the outer surface of the CPL filter body 412 back and forth until the dirt on the surface of the CPL filter body 412 is cleaned. After the surface of the CPL filter body 412 is cleaned, turn off the driving motor 502, and then retract the multi-stage electric telescopic rod 505 to the shortest length, so that the light of the CPL filter body 412 can pass through the filter more accurately, reduce phenomena such as scattering and blurring caused by dirt, and make the captured image clearer and sharper.

[0042] Usage method and working principle of this device: When it is necessary to use the CPL filter to adjust the quality of the captured image, first, sleeved the threaded tube 401 on the surface of the mounting shaft 2, and rotate the threaded tube 401 so that the threaded tube 401 is threadedly connected to the mounting shaft 2, thereby fixing the threaded tube 401 on the outer surface of the camera body 1, and further fixing the CPL filter body 412 on the outer surface of the camera body 1. Then, turn on the photosensitive sensor 3. When the photosensitive sensor 3 detects that the ambient light is too high and it is necessary to increase the image saturation, first start the forward and reverse motor 407 to drive the rotation shaft 408 to rotate, and then drive the driving gear 409 to rotate. The driving gear 409 drives the toothed ring 403 to rotate. Then, electrically connect multiple first electromagnets 405 to an external power source to generate a magnetic field, so that multiple first iron blocks 419 move towards the direction of the multiple first electromagnets 405 under the action of the magnetic force, thereby driving multiple moving rods 418 to move towards the direction of the first electromagnets 405, and further causing multiple springs 417 to elongate. Under the attraction of the magnetic force, when the toothed ring 403 rotates, it drives multiple first electromagnets 405 to rotate, and then drives the CPL filter body 412 to rotate. When the photosensitive sensor 3 detects that the quality of the image captured in the camera body 1 reaches the required quality, it transmits a signal to an external control device, and the forward and reverse motor 407 can be turned off through the external control device. On the contrary, when it is necessary to reduce the saturation of the captured image, start the forward and reverse motor 407 in the reverse direction to drive the CPL filter body 412 to rotate in the reverse direction. Since the camera body 1 is often used for external shooting and the external environment is changeable, when the CPL filter body 412 rotates to the required angle, because most of the forward and reverse motors 407 on the existing market do not have a self-locking function and the positioning effect is relatively poor, in order to prevent the position of the CPL filter body 412 from shifting due to external collisions and affecting the shooting effect, first disconnect the connection between multiple first electromagnets 405 and the external power source, so that multiple first iron blocks 419 are no longer attracted by the external magnetic field, and all reset under the elastic action of the springs 417. Then, electrically connect the second electromagnet 424 to the external power source to generate a magnetic field, so that multiple second iron blocks 421 move towards the direction of the second electromagnet 424 under the influence of the magnetic force, and are tightly connected to the second electromagnet 424, thereby fixing the multiple second iron blocks 421, and further fixing the CPL filter body 412. When the photosensitive sensor 3 detects dirt on the surface of the CPL filter body 412, first start the drive motor 502 to drive the connecting shaft 503 to rotate, and then drive the carrier 504 to rotate. At the same time, start the multi-stage electric telescopic rod 505 to make it extend and retract back and forth, drive the moving block 506 to move back and forth, and then drive the sponge block 507 to move back and forth. Through the rotation of the carrier 504, the sponge block 507 wipes the outer surface of the CPL filter body 412 back and forth until the dirt on the surface of the CPL filter body 412 is cleaned. When the cleaning of the surface of the CPL filter body 412 is completed, turn off the drive motor 502.Then, the multi-stage electric telescopic rod 505 can be retracted to the shortest. Among them, the external control device is electrically connected to the camera body 1, the photosensitive sensor 3, the first electromagnet 405, the forward and reverse motor 407, the second iron block 421, the second electromagnet 424, the driving motor 502, and the multi-stage electric telescopic rod 505.,

[0043] The wiring diagrams of the camera body 1, the photosensitive sensor 3, the first electromagnet 405, the forward and reverse motor 407, the second iron block 421, the second electromagnet 424, the driving motor 502, and the multi-stage electric telescopic rod 505 in the present invention belong to the common knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the camera body 1, the photosensitive sensor 3, the first electromagnet 405, the forward and reverse motor 407, the second iron block 421, the second electromagnet 424, the driving motor 502, and the multi-stage electric telescopic rod 505 will not be explained in detail.,
