Description

Technical Field

[0001] This utility model relates to the field of photography and videography technology, and in particular to a gear adjustment structure and a camera. Background Technology

[0002] In equipment such as cameras, camcorders, or fill lights, it is often necessary to set various parameters to meet the needs of shooting.

[0003] For example, existing cameras typically use function buttons and front / rear adjustment buttons to select shooting and image editing parameters. This operation method is relatively complex and outdated, affecting the user's photography experience. Furthermore, having too many buttons on the camera body results in numerous openings on the camera casing, detracting from the camera's aesthetics. Utility Model Content

[0004] The purpose of this invention is to provide a gear adjustment structure that facilitates gear adjustment and improves the user experience.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: According to one aspect of the present invention, a gear adjustment structure is provided, the gear adjustment structure comprising: a mounting base having a receiving portion and a connecting portion, the receiving portion being located inside the connecting portion in the radial direction; a connecting base mounted on the connecting portion; a rotating ring mounted between the connecting base and the mounting base, the connecting base and the mounting base being capable of limiting the rotating ring in the axial and radial directions, the rotating ring being capable of rotating relative to the connecting base, the inner surface of the rotating ring having a plurality of adjustment portions, the plurality of adjustment portions being arranged around the central axis of the rotating ring; and a detection switch housed within the receiving portion, the detection switch comprising an actuating portion and a detection portion, the actuating portion being connected to the detection portion, the detection portion being electrically connected to a control unit, the actuating portion being capable of extending into the adjustment portion, and when the rotating ring rotates relative to the connecting base, the adjustment portion being capable of driving the actuating portion to swing relative to the detection portion, so as to transfer from one adjustment portion to an adjacent adjustment portion, and causing the detection portion to generate a detection signal.

[0006] In one embodiment of this application, the inner surface of the rotating ring is provided with a protrusion in the radial direction. There are multiple protrusions, and the multiple protrusions are arranged around the central axis of the rotating ring. The protrusions are symmetrically provided with two inclined segments, which are connected and inclined from their connection point toward the inner surface of the rotating ring, so as to form the adjustment part between two adjacent protrusions.

[0007] In one embodiment of this application, the gear adjustment structure further includes a limiting member and a resetting member. The limiting member is mounted on the connecting portion and can move relative to the mounting base in the radial direction of the mounting base to switch between a limiting position and a clearance position. When the limiting member is in the limiting position, the limiting member can abut against the adjusting portion to restrict the rotation of the rotating ring relative to the connecting base. When the limiting member is in the clearance position, the limiting member separates from the rotating ring, allowing the rotating ring to rotate relative to the connecting base. The resetting member is connected between the mounting base and the limiting member to abut against the adjusting portion.

[0008] In one embodiment of this application, the end of the limiting member away from the reset member is provided with an inclined guide surface, the guide surface being adapted to the inclined segment so that when the rotating ring rotates relative to the connecting seat, the guide surface can move relative to the inclined segment, and the limiting member can abut against the adjacent adjustment portion.

[0009] In one embodiment of this application, the two opposite sides of the actuating part are inclined in the circumferential direction of the rotating ring, so that when the rotating ring rotates clockwise or counterclockwise, the adjusting part can drive the actuating part to swing relative to the detection part clockwise or counterclockwise.

[0010] In one embodiment of this application, the connecting seat is provided with a limiting portion and a limiting perimeter. The limiting perimeter protrudes from the limiting portion along the axial direction of the connecting seat. The limiting perimeter is used to sleeve the rotating ring to limit the radial direction of the rotating ring. The limiting portion is used to abut against the axial end of the rotating ring to limit the rotating ring between the mounting seat and the connecting seat.

[0011] In one embodiment of this application, a first notch and a second notch are provided on the limiting perimeter, the first notch and the second notch are spaced apart, and the detection switch and the limiting member respectively abut against the adjusting part through the first notch and the second notch.

[0012] This application also provides a camera, the camera including a housing, a main board and any of the aforementioned gear adjustment structures, the housing having a mounting cavity, the main board being mounted in the mounting cavity, the housing having a mounting base formed thereon, and the receiving portion communicating with the mounting cavity, the detection switch being mounted on the main board and housed within the receiving portion.

[0013] In one embodiment of this application, the camera further includes an image module and a lens assembly. The image module is mounted on the motherboard and is disposed corresponding to the receiving portion. A through-type photography channel is provided on the connector, which communicates with the receiving portion and is disposed corresponding to the image module. The lens assembly is connected to the connector and covers the end of the photography channel away from the image module.

[0014] In one embodiment of this application, the camera further includes a front shutter and a shutter button. The front shutter is disposed on the motherboard, and the shutter button is mounted on the housing and located on the same side as the mounting base. The shutter button corresponds to the front shutter.

[0015] In one embodiment of this application, the camera further includes a selfie mirror, which is mounted on the connector and located on the side of the connector opposite to the mounting base.

[0016] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this invention, the gear adjustment structure includes a mounting base, a connecting base, a rotating ring, and a detection switch. The mounting base has a receiving portion and a connecting portion, with the receiving portion located radially inside the connecting portion. The connecting base is mounted on the connecting base, and the rotating ring is connected between the mounting base and the connecting base, allowing it to rotate relative to either the mounting base or the connecting base. The mounting base and the connecting base also limit the rotation of the rotating ring in both the axial and radial directions. Multiple adjustment portions are provided on the inner surface of the rotating ring, arranged around its central axis. The detection switch is housed within the receiving portion and includes an actuating portion and a detection portion. The actuating portion is connected to the detection portion, and the detection portion is electrically connected to the control unit. The actuating portion extends into the adjustment portion. When the rotating ring rotates relative to the connecting base, the adjustment portion causes the actuating portion to swing relative to the detection portion, transferring the actuating portion from one adjustment portion to an adjacent adjustment portion. This generates a detection signal in the detection portion, thus completing one gear adjustment. Because the rotating ring has multiple adjustment parts, it can adjust multiple gears with one rotation. The gear adjustment is achieved by rotating the rotating ring, which makes the adjustment operation feel similar to the operation of focusing a lens, thus facilitating gear adjustment and improving the user experience.

Detailed Implementation

[0026] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0027] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Existing cameras typically use function buttons and front / rear adjustment buttons to select shooting and image editing parameters. This operation method is relatively complex and outdated, affecting the user's photography experience. Furthermore, having too many buttons on the camera body results in numerous openings on the camera casing, impacting the camera's aesthetics. Therefore, this paper proposes a new level adjustment structure to solve the above problems.

[0030] The solution is further illustrated by the following examples: Figure 1 This is a schematic diagram of a camera according to an embodiment of the present invention. Figure 2 yes Figure 1 A partial cross-sectional view of the camera. Figure 3 yes Figure 2 A magnified view of point A. Figure 4 yes Figure 2 Enlarged view of point B. Figure 5 yes Figure 1 An exploded view of the camera. Figure 6 yes Figure 5 Enlarged view of point C.

[0031] Please see Figure 1 and Figure 2 The camera in this embodiment may include a housing 10, a main board 20, and a gear adjustment structure 30. The housing 10 has a mounting cavity 11, and the main board 20 is mounted within the mounting cavity 11. A mounting base 31 is formed on the housing 10, and a receiving portion 311 communicates with the mounting cavity. A detection switch 35 is mounted on the main board 20 and housed within the receiving portion 311, so that the detection signal generated by the gear adjustment structure 30 is transmitted to the control unit on the main board 20, thereby enabling the control unit to recognize the corresponding gear adjustment.

[0032] See Figure 5 The housing 10 may include a front housing 101 and a rear housing 102, with the front housing 101 connected to the rear housing 102 to form a mounting cavity 11 between the front housing 101 and the rear housing 102.

[0033] In this embodiment, the mounting base 31 is formed on the front shell 101, and the receiving portion 311 is formed in the through hole on the front shell 101, so that the receiving portion 311 communicates with the mounting cavity 11.

[0034] Meanwhile, the motherboard 20 may include a main PCB board 201 and a secondary PCB board 202, and the secondary PCB board 202 is electrically connected to the main PCB board 201 via a flexible flat cable.

[0035] See Figure 2 and Figure 5 The camera may also include an image module 21 and a lens assembly 22. The image module 21 is configured as an image sensor, enabling it to convert the light image on the photosensitive surface into an electrical signal proportional to the light image using the photoelectric conversion function of the optoelectronic device.

[0036] In this embodiment, the image module 21 is mounted on the motherboard 20, that is, the image module 21 is mounted on the sub-PCB board 202 and is positioned corresponding to the receiving part 311. At the same time, the connecting seat 32 of the gear adjustment structure 30 has a through-type photography channel 325, which connects to the receiving part 311 and is positioned corresponding to the image module 21. The lens assembly 22 is connected to the connecting seat 32 and covers the end of the photography channel 325 away from the image module 21, so that the light image passes through the lens assembly 22 and is transmitted to the image module 21 along the photography channel 325 and the receiving part 311.

[0037] Specifically, the lens assembly 22 may include a lens 221 and a cover plate 222. The lens 221 is connected to the connector 32 and is positioned corresponding to the image module 21 and the photography channel 325, so that light passing through the lens 221 can be focused onto the image module 21, improving the shooting effect. At the same time, the cover plate 222 is installed on the lens 221, so that the cover plate 222 can protect the lens 221, and the cover plate 222 and the lens 221 can protect the image module 21.

[0038] See Figure 2 and Figure 5The camera may also include a front shutter 23 and a shutter button 24. The front shutter 23 is located on the motherboard 20, i.e., mounted on the main PCB board 201. Simultaneously, the shutter button 24 is mounted on the housing 10 and located on the same side as the mounting base 31. The shutter button 24 is configured corresponding to the front shutter 23, allowing users to take selfies using both the front shutter 23 and the shutter button 24, facilitating handheld selfies. Specifically, the front housing 101 has a front mounting hole 103 for mounting the shutter button 24, facilitating selfie operation.

[0039] In this embodiment, the camera may also include a selfie mirror 25. The selfie mirror 25 is mounted on the connector 32 and is located on the side of the connector 32 away from the mounting base 31. That is, when the user holds the camera to take a selfie, the selfie mirror 25 is positioned facing the user, so that the user can take a selfie based on the pattern reflected in the selfie mirror 25, thereby improving the selfie effect and enhancing the user experience.

[0040] In addition, the camera may also include a flash unit 26 and a lampshade assembly 27. The flash unit 26 is mounted on the main board 20, and the lampshade assembly 27 is connected to the housing 10 and located on the same side as the mounting base 31. The lampshade assembly 27 is configured to correspond to the flash unit 26, so that the flash emitted by the flash unit 26 can better illuminate the object being photographed after passing through the lampshade assembly 27, thereby improving the shooting effect.

[0041] In this embodiment, the lampshade assembly 27 may include a lens 271, a mounting bracket 272, and a light-transmitting aperture cover 273. The front housing 101 has a through-hole flash window 104, which corresponds to the flash lamp 26. The mounting bracket 272 is installed within the flash window 104 and is annular. The light-transmitting aperture cover 273 is mounted on the mounting bracket 272 and located within the inner ring of the mounting bracket 272. The light-transmitting aperture cover 273 has a through-hole rectangular opening for light transmission. The lens 271 is mounted on the mounting bracket 272 and is located downstream of the light-transmitting aperture cover 273 in the light-emitting direction. Specifically, the light-transmitting aperture cover 273 is a Fresnel lens to improve the illumination effect of the flash lamp.

[0042] See Figure 5 The gear adjustment structure 30 may include a mounting base 31, a connecting base 32, a rotating ring 33, a limiting member 34, and a detection switch 35.

[0043] The mounting base 31 includes a receiving portion 311 and a connecting portion 312, with the receiving portion 311 located radially inside the connecting portion 312. In this embodiment, the mounting base 31 is formed on the front housing 101, and the receiving portion 311 is configured as a through hole on the front housing 101. The connecting portion 312 is located on the circumferential side of the end of the through hole, allowing the connecting portion 312 to be used to connect to the connecting base 32. In other embodiments, the mounting base 31 can be independently provided and can be connected to a mounting surface.

[0044] Meanwhile, the connector 32 is mounted on the connector 312. Specifically, the connector 32 can be connected to the connector 312 by screws to connect the connector 32 to the mounting base 31. In some other embodiments, the connector 32 can also be connected to the connector 312 by snap-fit.

[0045] Furthermore, the rotating ring 33 is installed between the connecting seat 32 and the mounting seat 31, and the connecting seat 32 and the mounting seat 31 can limit the axial and radial directions of the rotating ring 33 to prevent the rotating ring 33 from shifting relative to the axial and radial directions of the mounting seat 31. In some other embodiments, the rotating ring 33 can be directly connected to the mounting seat 31. For example, the rotating ring 33 can be connected to the mounting seat 31 through a sliding block and a sliding groove, so that the mounting seat 31 can limit the radial and axial directions of the rotating ring 33 and allow the rotating ring 33 to rotate about the central axis of the mounting seat 31.

[0046] In this embodiment, the rotating ring 33 can rotate relative to the connecting seat 32. Specifically, the rotating ring 33 can rotate around the central axis of the connecting seat 32, that is, the rotating ring 33 can rotate around its own central axis. It should be noted that the central axes of the mounting seat 31 and the connecting seat 32 coincide, and their central axes are the axes within the imaging channel 325.

[0047] Meanwhile, the inner side of the rotating ring 33 is provided with a plurality of adjustment parts 331, and the plurality of adjustment parts 331 are arranged around the central axis of the rotating ring 33, that is, the plurality of adjustment parts 331 are distributed along the inner side of the rotating ring 33.

[0048] In this embodiment, the limiting member 34 is mounted on the connecting portion 312 and can move relative to the mounting base 31 in the radial direction, allowing the limiting member 34 to switch between a limiting position and an aggression position. Specifically, when the limiting member 34 is in the limiting position, it abuts against the adjusting portion 331 to restrict the rotation of the rotating ring 33 relative to the connecting base 32, i.e., locking the rotating ring 33 and preventing it from rotating around itself. When the limiting member 34 is in the aggression position, it separates from the rotating ring 33, i.e., unlocking the rotating ring 33, allowing it to rotate relative to the connecting base 32, i.e., enabling the rotating ring 33 to rotate around its own central axis.

[0049] Furthermore, the detection switch 35 is housed within the receiving portion 311. Specifically, the detection switch 35 is a surface mount type and is mounted on the main board 20. The detection switch 35 is mounted on the sub-PCB board 202 and located within the receiving portion 311.

[0050] Meanwhile, the detection switch 35 may include an actuating part 351 and a detection part 352. The actuating part 351 is connected to the detection part 352, and the detection part 352 is electrically connected to the control unit. The detection part 352 is encapsulated within the encapsulation structure of the detection switch 35, and the actuating part 352 may be configured as a lever, which can swing relative to the detection part 352.

[0051] At the same time, the actuating part 351 can extend into the adjusting part 331. When the rotating ring 33 rotates relative to the connecting seat 32, the adjusting part 331 can drive the actuating part 351 to swing relative to the detection part 352, so that the actuating part 351 is transferred from one adjusting part 331 to an adjacent adjusting part 331, and the detection part 352 generates a detection signal.

[0052] See Figure 3 and Figure 6 In this embodiment, the actuation unit 351 is the toggle lever of the detection switch 35. When the actuation unit 351 swings a certain distance relative to the body of the detection switch 35 or the detection unit 352, the detection unit 352 can identify the operation action, form a detection signal, and transmit it to the control unit, so that the control unit can control the adjustment of the gear and parameters according to the detection signal.

[0053] Specifically, the actuating part 351 is inclined on both sides of the rotating ring 33 along its circumference. When the rotating ring 33 rotates clockwise or counterclockwise, the adjusting part 331 can drive the actuating part 351 to swing clockwise or counterclockwise relative to the detection part 352, thereby realizing bidirectional adjustment of the gear or parameter. For example, when the actuating part 351 rotates clockwise relative to the detection part 352, the detection part 352 generates a detection signal, causing the control unit to increment the gear or parameter by one; when the actuating part 351 rotates counterclockwise relative to the detection part 352, the detection part 352 generates a detection signal, causing the control unit to decrement the gear or parameter by one, thus allowing the operator to achieve bidirectional adjustment of the gear or parameter by rotating the rotating ring 33 clockwise or counterclockwise.

[0054] The actuating unit 351 can swing relative to the body of the detection switch 35 in a first direction and a second direction. The first and second directions are located in the same plane and are arranged in opposite directions. Figure 3 As shown, the actuation unit 351 can swing upward relative to the body of the detection switch 35, or it can swing downward relative to the body of the detection switch 35.

[0055] In this embodiment, when the rotating ring 33 rotates around its own axis, the adjusting part 331 can abut against and drive the actuating part 351 to swing until the actuating part 351 enters the adjacent adjusting part 331. At this time, the detection switch 35 sends a detection signal, and the control unit can identify the gear level and adjust it by one level based on the detection signal. At the same time, since multiple adjusting parts 331 are provided on the inner side of the rotating ring 33, when the rotating ring 33 is rotated, the control unit can identify the position of the rotating ring 33, i.e., the gear level of the rotating ring 33, through the detection signal sent by the detection switch 35, and thus realize the adjustment of multiple gear levels. This allows the control unit to control the adjustment of parameters such as shooting parameters and image editing parameters according to the change of gear level.

[0056] It should be noted that because the rotating ring 33 is ring-shaped and has multiple adjustment parts 331, multiple adjustment levels can be achieved by rotating the rotating ring 33 one revolution. The level adjustment is achieved by rotating the rotating ring 33, making the adjustment operation feel similar to lens focusing, thus facilitating level adjustment and improving the user experience. At the same time, the level adjustment structure 30 is integrated with the lens assembly 22, thus avoiding the need for multiple mounting holes on the housing 10 and improving the camera's aesthetics.

[0057] In addition, the gear adjustment structure 30 can be applied not only to cameras, but also to devices that require parameter adjustment, such as flash units, fill lights, camcorders, or instant cameras, to facilitate the gear adjustment or parameter adjustment of flash units and fill lights.

[0058] Figure 7 This is a schematic diagram of the rotating ring of the gear adjustment structure of this application. Figure 8 This is a schematic diagram of the connecting seat of the gear adjustment structure of this application.

[0059] See Figure 7 The inner surface of the rotating ring 33 is provided with a protrusion 332 in the radial direction. Multiple protrusions 332 are provided, and these protrusions 332 are arranged around the central axis of the rotating ring 33. Simultaneously, each protrusion 332 has two symmetrically arranged inclined segments 333 connected to each other, and both inclined segments 333 are inclined towards the inner surface of the rotating ring 33 from their connection point, thereby forming an adjustment section 331 between two adjacent protrusions 332.

[0060] In this embodiment, the protrusion 332 is also provided with a support section 334. One end of the support section 334 is connected to the inner side of the rotating ring 33, and the other end is connected to the junction of the two inclined surfaces 333 to support the two inclined surfaces 333, thereby enhancing the structural strength of the protrusion 332.

[0061] In this embodiment, the support section 334 and the two inclined surfaces 333 together form a hollow protrusion 332. Specifically, the hollow design of the protrusion 332 facilitates the casting and demolding of the rotating ring 33, and avoids material accumulation at the protrusion 332, which could lead to defective castings.

[0062] See Figure 4 and Figure 5 The gear adjustment structure 30 may also include a reset member 36. The reset member 36 is connected between the mounting base 31 and the limiting member 34 to abut the limiting member 34 against the adjustment part 331.

[0063] Specifically, the connecting portion 312 of the mounting base 31 is provided with a mounting position 313 for mounting the reset member 36 and the limiting member 34.

[0064] In this embodiment, the reset member 36 can be configured as a reset spring, so that the reset member 36 can drive the limiting member 34 to abut against the adjusting part 331. In other embodiments, the reset member 36 can be configured as a spring sheet, elastic rubber, etc., so as to drive the limiting member 34 to abut against the adjusting part 331.

[0065] Meanwhile, the end of the limiting member 34 away from the resetting member 36 is provided with an inclined guide surface 341, and the guide surface 341 is adapted to the inclined section 333 so that when the rotating ring 33 rotates relative to the connecting seat 32, the guide surface 341 can move relative to the inclined section 333, thereby facilitating the rotation of the rotating ring 33. At the same time, when the rotating ring 33 rotates, the inclined surface 333 can push the limiting member 34 through the guide surface 341 to overcome the compression of the resetting member 36, so that the limiting member 34 moves relative to the mounting seat 31, so that the limiting member 34 disengages from the rotating ring 33 and can then abut against the adjacent adjusting part 331.

[0066] It should be noted that both the guide surface 341 and the inclined surface 333 are inclined, which can prevent the limiting member 34 and the adjusting part 331 of the rotating ring 33 from forming a mechanical self-lock, thereby facilitating the rotation of the rotating ring 33.

[0067] Furthermore, the gear adjustment structure 30 is equipped with a limiting member 34 and a resetting member 36, which can provide feedback on the rotation of the rotating ring 33. This allows the operator to intuitively and clearly feel the rotation range of the rotating ring 33, thus providing a clearer sense of gear or parameter adjustment. Specifically, when the limiting member 34 jumps from one adjustment section 331 to another, the rotating ring 33 will provide a noticeable jerking or jumping feedback to the operator, allowing the operator to intuitively feel the gear adjustment and preventing the rotating ring 33 from rotating too quickly and causing multiple gear adjustments to be made consecutively. (See also...) Figure 8The connecting seat 32 may be provided with a limiting portion 321 and a limiting edge 322. Specifically, the limiting edge 322 protrudes from the limiting portion 321 along the axial direction of the connecting seat 32, and the limiting edge 322 is used to sleeve the rotating ring 33, so that the limiting edge 322 can limit the radial direction of the rotating ring 33. At the same time, the limiting portion 321 is used to abut against the axial end of the rotating ring 33 to limit the rotating ring 33 between the mounting seat 31 and the connecting seat 32.

[0068] Meanwhile, a first notch 323 and a second notch 324 are provided on the limiting edge 322, with the first notch 323 and the second notch 324 spaced apart. The detection switch 35 and the limiting member 34 abut against the adjusting part 331 through the first notch 323 and the second notch 324, respectively. Since the detection switch 35 is mounted on the main board 20 and located in the receiving part 311, and the limiting member 34 is connected in the connecting part 312, the detection switch 35 and the limiting member 34 need to pass through the first notch 323 and the second notch 324 to abut against or extend into the adjusting part 331.

[0069] In summary, the mounting base 31 is provided with a receiving portion 311 and a connecting portion 312, and the receiving portion 311 is located inside the connecting portion 312 in the radial direction. The connecting base 32 is mounted on the connecting base 32, and the rotating ring 33 is connected between the mounting base 31 and the connecting base 32, and can rotate relative to either the mounting base 31 or the connecting base 32. Simultaneously, the mounting base 31 and the connecting base 32 can limit the axial and radial directions of the rotating ring 33. Multiple adjusting portions 331 are provided on the inner surface of the rotating ring 33, and these adjusting portions 331 are arranged around the central axis of the rotating ring 33. The detection switch 35 is housed within the receiving portion 311. The detection switch 35 includes an actuating portion 351 and a detection portion 352. The actuating portion 351 is connected to the detection portion 352, and the detection portion 352 is electrically connected to the control unit. Simultaneously, the actuating part 351 can extend into the adjusting part 331. When the rotating ring 33 rotates relative to the connecting seat 32, the adjusting part 331 can cause the actuating part 351 to swing relative to the detection part 352, so that the actuating part 351 is transferred from one adjusting part 331 to an adjacent adjusting part 331, and the detection part 352 generates a detection signal, thereby completing one gear adjustment. Since the rotating ring 33 is provided with multiple adjusting parts 331, multiple gear adjustments can be achieved by rotating the rotating ring 33 in one revolution. Moreover, gear adjustment is achieved by rotating the rotating ring 33, which makes the adjustment operation feel similar to the focusing operation of the lens 221, thereby facilitating gear adjustment and improving the user experience.
