Description

[Technical field]

[0001] The present invention relates to an optical accessory adapter ring, and more particularly to a crushable optical accessory adapter ring which reduces the thickness of the frame and can be broken by an external force. [Background technology]

[0002] With the rapid development of digital and optical technologies, various digital products are constantly improving in both function and performance, and are becoming more and more popular with decreasing prices. In general, when users take pictures with a camera, they usually attach filters with different effects (such as soft focus filters, star effect filters, polarizing filters, ND filters, color filters, etc.) to the camera lens to obtain various different image effects. In addition, users may also attach separate protective lenses to the camera lens and filters to protect the camera lens and the aforementioned filters.

[0003] With the advancement of various image processing software, many of the above filters are gradually being replaced by powerful digital technology, but among them, polarizing filters, ND filters, and protective filters are still very difficult to replace. As the name suggests, ND filters are filters that reduce the light transmittance, and are generally divided into several different standards according to the light transmittance. Consumers can attach single or multiple ND filters of different standards to the lens according to the actual needs of shooting, thereby appropriately reducing the amount of light passing through the lens and enabling shooting under an environment with a strong light source. Polarizing filters are filters manufactured based on the polarization principle of light, and the amount of light passing through at a certain polarization angle can be adjusted by rotating the polarizing filter. By attaching a polarizing filter to the lens and properly adjusting the angle of the polarizing filter, consumers can effectively eliminate the reflected light on the surface of an object (e.g., the surface of water, the glass of a show window, or the surface of plant leaves) and obtain an ideal shooting effect. Protective filters are intended to protect the camera lens, polarizing filter, or ND filter, and to prevent scratches caused by external dust (e.g., quartz sand) and damage caused by impact.

[0004] In addition, different camera lenses, filters, and protective filters may have different apertures due to different brands and design standards. In order to connect optical accessories with different apertures, adapter rings are usually used as a connection medium, so that users do not need to purchase filters or protective filters that correspond to the camera lens separately, which can reduce the purchase cost of photography equipment and the storage space it occupies.

[0005] However, when conventional adapter rings are connected to filters or protective filters having external threads or threads, improper fitting often occurs. For example, due to the low production rate of the internal threads of the adapter ring, jamming may occur when the filter or protective filter is screwed into the adapter ring. In this case, when attempting to destroy the adapter ring by external force, it is difficult to accurately apply the appropriate force due to the material and thickness (about 2 mm) of the adapter ring, and it may even indirectly damage the filter or protective filter. Therefore, it is an important objective of the present invention to effectively solve the above problems and improve the convenience of destroying the adapter ring. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to solve the above-mentioned problems, the inventors have repeatedly conducted research and testing, and finally developed the crushable optical accessory adapter ring of the present invention. It is expected that the present invention can effectively solve the problems of the past and provide a better usage experience for businesses and / or users. [Means for solving the problem]

[0026] The present invention relates to a collapsible optical accessory adapter ring, which is applied to a camera C. In a first embodiment, referring to FIG. 1, a collapsible optical accessory adapter ring A is for connecting two first optical accessories L and a second optical accessory F with different apertures. Specifically, referring to FIG. 2, the collapsible optical accessory adapter ring A includes at least one frame 1. The frame 1 is made of metal material (e.g., aluminum alloy) or plastic steel, but is not limited thereto. And it is a hollow ring as a whole. For the sake of simplicity, the lower left of FIG. 2 is the front direction of the element, the upper right of FIG. 2 is the rear direction of the element, the upper side of FIG. 2 is the upper (top) direction of the element, and the lower side of FIG. 2 is the lower (bottom) direction of the element. In addition, the embodiment of the collapsible optical accessory adapter ring A of the present invention is not limited to that shown in the diagram of the present invention. The vendor can adjust the appearance shape of the collapsible optical accessory adapter ring A according to the requirements of the product. Therefore, if the collapsible optical accessory adapter ring A has the basic structure and effects described later in this invention, it is a collapsible optical accessory adapter ring A that is protected by the present invention.

[0027] Referring to the above, as shown in FIG. 1 to FIG. 3B, when viewed from the side, the outer diameters of the opposing ends of the frame 1 are different, and the frame 1 is divided into a first adapter end D1 and a second adapter end D2. The first adapter end D1 is located at one end (e.g., the rear end) of the frame 1 and is adapted to a first aperture related to a first optical accessory L. A first connecting portion 11 (e.g., an external thread) is provided on the outer wall surface of the first adapter end D1, and is connected to the first optical accessory L (e.g., various lenses such as a wide-angle lens, a telephoto lens, a fixed focus lens, a zoom lens, or various functional lenses such as a protective filter, a polarizing filter, a filter, etc.) via the first connecting portion 11. The second adapter end D2 is located at the other end (e.g., the front end) of the frame 1 and is adapted to a second aperture related to a second optical accessory F. A second connecting portion 13 (e.g., an internal thread) is provided on the inner wall surface of the second adapter end D2, and is connected to the second optical accessory F via the second connecting portion 13. In the first embodiment, the inner diameter of the second adapter end D2 may be larger than the outer diameter of the first adapter end D1, and the second bore may be larger than the first bore, but is not limited thereto. In other embodiments of the present invention, according to the actual needs of the product, the first connecting part 11 and the second connecting part 13 may adopt other fixing structures other than screws.

[0028] Please refer to FIG. 2 to FIG. 6. In the first embodiment, the frame 1 is provided with a plurality of force application parts 15 and a plurality of crushing parts 17. The force application parts 15 extend outward from the outer wall surface of the frame 1. As shown in FIG. 4, the force application parts 15 located at the upper part of the frame 1 protrude upward and extend, and the force application parts 15 located at the lower part of the frame 1 protrude downward and extend. Each force application part 15 is provided with a through hole 150, and a user can apply force to the force application part 15 by pinching the force application part 15 with a hand or inserting a removal tool (e.g., a hairpin, a key, a bamboo skewer, etc.) into the through hole 150. In the first embodiment, the force application part 15 is integrally formed with the frame 1, but is not limited thereto. In other embodiments of the present invention, the force application part 15 can be fixed to the frame 1 as an independent part by a method such as welding, bonding, riveting, fitting, or screwing. If the force application part 15 is subjected to force by a user and the crushing part 17 can be deformed and broken as described below, it is the force application part 15 referred to in the present invention. In addition, the size and shape of the through hole 150 can be adjusted according to the actual needs of the product, and when a plurality of force application parts 15 are provided on the frame 1, the shapes of the through holes 150 provided on each force application part 15 can be the same or different, and even no through hole 150 may be provided. The user can apply force by directly pinching the force application part 15 with his / her fingers, or by clamping the force application part 15 with another removal tool (e.g., a wrench).

[0029] Also, referring again to FIG. 2 to FIG. 6, the crushed portion 17 is located on the frame 1, and the thickness of the area where the crushed portion 17 is located is intentionally designed to be thinner than the main portion of the frame 1. It is particularly noted here that the aforementioned "main portion of the frame 1" refers to the core and basic structural portion of the frame 1, and does not include other additional, functional or decorative portions, such as screws, anti-slip patterns, etc. In addition, the main portion of the frame 1 usually has a thicker and stronger structure, providing sufficient strength and stability to allow the crushable optical accessory adapter ring A to be used normally. In addition, the crushed portion 17 can be adjacent to the force application portion 15. Thus, when the force application portion 15 is applied with a force and moves in a first direction, the aforementioned force is transmitted to the main portion of the frame 1. Due to the thin thickness of the crushed portion 17, its structural strength is low, and as a result, it is less resistant to force than other portions of the frame 1. In this situation, the crushed portion 17 first reaches its endurance limit, deforms, and begins to break. The above-mentioned deformation and rupture concentrates more force on the area where the crushed portion 17 is located, accelerating the deformation and rupture of the crushed portion 17, and the frame 1 is broken and torn along the extension direction of the crushed portion 17. It is particularly noted that the term "adjacent" in the present invention refers to two structural features being close to each other, and when one of the structural features receives a force, the force can be transmitted to the other structural feature and affect it. For those skilled in the art, the term "adjacent" can be easily and clearly understood by the description and drawings of the present invention. In the best embodiment, "adjacent" can indicate that the two structural features are within 5 millimeters of each other in the shortest distance in three-dimensional space.

[0030] In light of the above, referring again to FIG. 2 to FIG. 6, in the first embodiment, the crushed portion 17 extends along the front-rear direction (i.e., the axial direction) of the frame 1. Here, the crushed portion 17 can be recessed in the inner wall surface of the second adapter end D2. In some embodiments, the crushed portion 17 can be located only in the inner wall surface having the second connecting portion 13 in the frame 1 (the crushed portion 17 closer to the upper side in FIG. 2 and FIG. 4). In some embodiments, the crushed portion 17 can be located in both the inner wall surface having the second connecting portion 13 and the inner wall surface not having the second connecting portion 13 in the frame 1 (the crushed portion 17 closer to the lower side in FIG. 2 and FIG. 4). The aforementioned "inner wall surface not having the second connecting portion 13" refers to the shoulder position formed by the connecting region of the second adapter end D2 and the first adapter end D1. Furthermore, the crushed portion 17 has an arc-shaped concave shape, and the thinnest part thereof can be 0.1 to 0.3 millimeters (but is not limited to this).

[0031] In addition, in order to further increase the breaking degree of the frame 1, referring to FIG. 2 to FIG. 6, in the first embodiment, the frame 1 further includes at least one auxiliary crushing portion 171. The auxiliary crushing portion 171 can be recessed in the outer wall surface of the first adapter end D1 and is disposed so as to substantially face one of the crushing portions 17. In this manner, when a user pulls the force application portion 15, the force applied to the force application portion 15 can deform and break the frame 1 along the crushing portion 17 and the auxiliary crushing portion 171. In some embodiments, the auxiliary crushing portion 171 can be located only on the outer wall surface of the frame 1 having the first connecting portion 11 (the auxiliary crushing portion 171 closer to the bottom in FIG. 5 and FIG. 6). In some embodiments, the auxiliary crushing portion 171 can be located on both the outer wall surface of the frame 1 having the first connecting portion 11 and the outer wall surface of the frame 1 not having the first connecting portion 11 (the auxiliary crushing portion 171 closer to the top in FIG. 5 and FIG. 6). The aforementioned "outer wall surface not having the first connecting portion 11" refers to the shoulder position formed by the connecting region of the first adapter end D1 and the second adapter end D2. Furthermore, the auxiliary crushed portion 171 has an arc-shaped recessed groove shape, and the thinnest part thereof can be 0.1 mm to 0.3 mm (but is not limited to this).

[0032] Further, referring back to FIG. 2 to FIG. 6, in the first embodiment, the frame 1 is provided with a plurality of force application portions 15, crushing portions 17 and auxiliary crushing portions 171, but is not limited thereto. In other embodiments of the present invention, the frame 1 can arbitrarily adjust the number of the force application portions 15, crushing portions 17 and auxiliary crushing portions 171 according to the needs of the product, and the aforementioned number can be at least one. Or, it can be provided with only the force application portions 15 and the crushing portions 17. Furthermore, the aspects of the crushing portions 17 and the auxiliary crushing portions 171 mentioned in the first embodiment can be simultaneously arranged on the frame 1, or only one aspect of them can be selected and arranged on the frame 1, which can increase the flexibility in the production of the crushable optical accessory adapter ring A.

[0033] Further, refer to FIG. 1 to FIG. 6 again. In the process of screwing the crushable optical accessory adapter ring A and the second optical accessory F, problems such as inaccurate installation angle, poor quality of the thread, dirt clogging in the thread gap, etc. occur, and improper fitting occurs, which will cause the phenomenon of screwing clogging (thread lock or bite) between the crushable optical accessory adapter ring A and the second optical accessory F. At that time, the user applies force to the force application part 15 by hand or using a disassembly tool, so that the frame 1 is broken along the extension direction of each crushing part 17. In this way, the frame 1 is deformed by its own destruction, and the aforementioned deformation usually causes both end points of the corresponding broken parts of the frame 1 to move away from each other, and the roundness of the crushable optical accessory adapter ring A is damaged. As a result, the user can directly apply force to the frame 1 in the subsequent process and easily remove it from the second optical accessory F, without causing any damage to the second optical accessory F. Also, although such a removal method renders the crushable optical accessory adapter ring A non-reusable, the price of the crushable optical accessory adapter ring A is generally much cheaper than the second optical accessory F (e.g., a polarizing filter, an ND filter, etc.) and can be considered a consumable item.

[0034] In the following, several aspects of the crushable optical accessory adapter ring A different from the first embodiment will be described, and the following description will mainly focus on the differences. In the second embodiment of the present invention, as shown in FIG. 7 and FIG. 8, the frame 1 is provided with two force application parts 25, two crushed parts 27, and an auxiliary crushed part 271, and the force application part 25 is located on the outer wall surface of the second adapter end D2 of the frame 1, and a through hole 250 (but not limited to this) is provided. The crushed part 27 is located on the inner wall surface of the second adapter end D2 and adjacent to the force application part 25. The auxiliary crushed part 271 is located in the connection area between the first adapter end D1 and the second adapter end D2, and extends along the circumferential direction of the frame 1. At least one end of the auxiliary crushed part 271 is adjacent to or connected to the crushed part 27. In the second embodiment, the cross-sectional structure of the auxiliary crushed part 271 is a V-shaped groove (but not limited to this). When a user applies force to each force application portion 25 by hand or using a removal tool, the crushing portion 27 first deforms and breaks along the axial direction of the frame 1, and then the auxiliary crushing portion 271 deforms and breaks along the circumferential direction of the frame 1, causing the frame 1 to break and split.

[0035] Following the above, please refer to FIG. 7 and FIG. 8 again. In the second embodiment, at least one fixing part 20 is provided on the outer wall surface of the frame 1, and the fixing part 20 can fix the collapsible optical accessory adapter ring A to other peripheral devices (for example: light shielding hood). Specifically, the fixing part 20 includes (but is not limited to) two sheet bodies, each sheet body is provided at a certain distance apart, and the screw structure of the light shielding hood can extend between them to achieve the effect of screwing in or out. However, it should be noted in advance that in other embodiments of the present invention, the actual structure of the fixing part 20 may also be changed according to the type of peripheral device.

[0036] In the third embodiment of the present invention, as shown in Figs. 9 to 11B, an opening 30 is provided on the outer peripheral surface of the second adaptor end D2 of the frame 1. The opening 30 has a hole diameter G1 on the outer wall surface (outer peripheral surface) of the frame 1 that is smaller than a hole diameter G2 on the inner wall surface (inner peripheral surface) of the frame 1, thereby forming a force application inclined surface 32. The opening 30 and the force application inclined surface 32 described above can both constitute the force application portion 35 of the present invention. The crushed portion 37 is recessed on the outer peripheral surface of the second adaptor end D2 and extends along the circumferential direction of the frame 1, but is not limited thereto. In other embodiments, the crushed portion 37 may be recessed on the inner peripheral surface of the second adaptor end D2, or may be recessed on both the outer peripheral surface and the inner peripheral surface of the second adaptor end D2 at the same time. A part of the crushed portion 37 may be disposed adjacent to the force application portion 35. When a user inserts a removal tool into the opening 30 at an oblique angle and presses it against the force application inclined surface 32, it is possible to apply a force to the force application inclined surface 32 (this corresponds to applying a force to the force application portion 35). In some embodiments, a support inclined surface 34 is provided at a position corresponding to the force application inclined surface 32 (but is not limited to this), and the removal tool comes into close contact with the support inclined surface 34 and can apply a force to the force application inclined surface 32 with the support inclined surface 34 as a fulcrum. Also, when the force application portion 35 moves in a first direction (for example, outward in the circumferential direction), a part of the crushing portion 37 adjacent to the force application portion 35 is deformed and broken first, and then the user can pull the force application portion 35 to tear the frame 1 along the extension direction of the crushing portion 37. In this way, if the crushable optical accessory adapter ring A is mistakenly mated with the second optical accessory F of FIG. 1, the user can use the force application portion 35 and the crushing portion 37 to break the connection between the crushable optical accessory adapter ring A and the second optical accessory F, thereby avoiding damaging the second optical accessory F.

[0037] In view of the above, in order to improve and accelerate the deformation and fracture state between the force application portion 35 and the crushing portion 37, as shown in Fig. 9 to Fig. 11B, in the third embodiment, the force application portion 35 may be provided with at least one recessed area 351. The recessed area 351 may be connected to the crushing portion 37, and the thickness of the recessed area 351 may be equal to or smaller than the thickness of the crushing portion 37. As shown in Fig. 11A, the force application portion 35 is provided with two recessed areas 351. One recessed area 351 is formed in a shape recessed inward from the outer peripheral surface of the frame 1, and the other recessed area 351 is formed in a shape recessed outward from the inner peripheral surface of the frame 1, but is not limited thereto. In another embodiment according to the present invention, only one recessed area 351 may be provided in the force application portion 35, and may be formed in a shape recessed from the outer peripheral surface or the inner peripheral surface. Furthermore, when the directions in which the crushed portion 37 and the recessed area 351 are recessed are different, for example, when the crushed portion 37 is recessed inward from the outer circumferential surface of the frame 1 and the recessed area 351 is recessed outward from the inner circumferential surface of the frame 1, the recessed area 351 does not communicate with the crushed portion 37 but is located adjacent to the crushed portion 37. This enhances the effect of stress concentration when the force application portion 35 receives a force, making it easier for a breaking point to be formed in the recessed area 351, which then extends to the crushed portion 37, forcing the crushed portion 37 to deform and break.

[0038] Again, as shown in FIG. 9 to FIG. 11B, at least one decorative block 38 is disposed on the frame 1 so as to protrude outward. In the third embodiment, the decorative block 38 is disposed in a ring shape so as to extend along the circumferential direction of the frame 1. The decorative block 38 may be located between the first connecting portion 11 and the crushing portion 37, and may be coated with a reflective material, a pigment, a coating of a metallic material, or a non-slip structure such as teeth. This increases the variety of appearances of the crushable optical accessory adapter ring A. Furthermore, at least one non-slip portion 39 may be provided on the outer peripheral surface of the second adapter end D2 of the frame 1. Each non-slip portion 39 may be configured with a structure for forming a rough surface such as a recess, a convex pattern, or a grain, and may increase the frictional force when the frame 1 is gripped and rotated. In this way, through the design of the non-slip portion 39, the user can grip the frame 1 more stably and connect or separate the first optical accessory L or the second optical accessory F of FIG. 1 and the crushable optical accessory adapter ring A.

[0039] In the fourth embodiment of the present invention, as shown in Fig. 12 and Fig. 13, the frame 1 is provided with a force application portion 45, a plurality of crushed portions 47, and an auxiliary crushed portion 471. Here, the force application portion 45 is at least one convex block, and each crushed portion 47 is recessed inward from the outer wall surface (outer peripheral surface) of the frame 1, and has a V-shaped cross section (however, in other embodiments, the above-mentioned cross section may be U-shaped, W-shaped, etc.), and at least one crushed portion 47 is adjacent to the force application portion 45. Also, the auxiliary crushed portion 471 is provided in an annular shape in the circumferential direction of the frame 1, like the crushed portion 37 in the third embodiment shown in Fig. 11B, and is located adjacent to each crushed portion 47. The auxiliary crushed portion 471 can be recessed from the outer wall surface (outer peripheral surface) or the inner wall surface (inner peripheral surface) of the frame 1. When an external force is applied to the force application portion 45, the frame 1 can be deformed and broken sequentially along the extending direction of the crushed portion 47 and the auxiliary crushed portion 471. In a modification of the fourth embodiment, the crushed portion 47 can be recessed from the inner wall surface (inner circumferential surface) of the frame 1 to the outside, such as the crushed portion 47 located in the middle as shown in FIG. 14. Furthermore, in other embodiments of the present invention, the number and arrangement of the crushed portions 47 and the auxiliary crushed portions 471 can be adjusted according to the needs of the product. For example, each crushed portion 47 and the auxiliary crushed portion 471 can be recessed from the inner wall surface (inner circumferential surface) of the frame 1 to the outside, so that the integrity of the appearance of the frame 1 can be maintained. Also, in the fourth embodiment, the crushed portions 47 are arranged in the circumferential direction, and in FIG. 12, the crushed portions 47 are arranged up and down, but in other embodiments, the crushed portions 47 can be arranged along the axial direction, that is, the size of the crushed portions 47 is reduced and they are arranged in order in the left and right direction of FIG. 12.

[0040] In a fifth embodiment of the present invention, as shown in Fig. 15A to Fig. 15B, the force application part 55 takes the form of an internal thread groove or a screw hole, into which a screw tool (e.g.: a screw, a screw driver) is screwed. The two crushing parts 57 are arranged on the opposite sides of the force application part 55 (not limited thereto). When a user uses a screw tool to screw into the force application part 55, the force is applied to the force application part 55 through the screw tool, causing a movement in a first direction, and at least one crushing part 57 is deformed and broken, destroying the roundness of the frame 1. In another embodiment, the frame 1 is provided with an auxiliary crushing part (not shown), and the user can tear the frame 1 along the auxiliary crushing part. Alternatively, the force application part 55 can be used in combination with the crushing part 37 and the recessed area 351 (e.g., a recessed area is provided at least at one end of the internal thread groove or screw hole) shown in the third embodiment of Fig. 11B, or in combination with only the crushing part 37 of the third embodiment. When a user tightens the screw tool onto the force application portion 55, the effect of the small thickness of the crushed portion 37 and / or the recessed area 351 can cause a fragile breaking effect.

[0041] In a sixth embodiment of the present invention, as shown in FIG. 16, the crushing portion 67 is composed of a plurality of holes 670, and these holes 670 are arranged along the circumferential direction of the frame 1. The minimum interval distance between adjacent holes 670 is 0.1 mm to 0.3 mm (but not limited thereto). Therefore, after a user applies force to the force application portion 65 (for example: a convex block) by hand and pulls the force application portion 65 outward from the frame 1, the hole walls of the adjacent holes 670 close to the force application portion 65 are crushed and broken due to their thinness. As a result, the frame 1 is destroyed along the extension direction of the crushing portion 67 (i.e., the arrangement direction of the holes 670). However, in other embodiments of the present invention, the holes 670 are arranged along the axial direction of the frame 1 (as in the left-right direction of FIG. 16), and the destruction effect of the frame 1 described above can be achieved in the same manner.

[0042] In the seventh embodiment of the present invention, as shown in Fig. 17 and Fig. 18, the second adaptor end D2 of the frame 1 is larger than the first adaptor end D1, so that a shoulder portion 76 is formed between the second adaptor end D2 and the first adaptor end D1. An inclined surface 761 is provided on the outside of the shoulder portion 76, and the inclined surface 761 is inclined in the direction from the second adaptor end D2 to the first adaptor end D1. A local portion of the inclined surface 761 corresponds to the connection portion of the two inner wall surfaces of the second adaptor end D2, and the thickness of this portion is thinner than other portions, thereby forming a crushed portion 77 (within the chain line circle in Fig. 18). In this way, when a user applies force to the force application portion 75 adjacent to the crushed portion 77, the force transmitted from the force application portion 75 to the frame 1 causes the crushed portion 77 (particularly the portion corresponding to the connection portion of the two inner wall surfaces) to deform and break due to excessive stress, and the frame 1 is destroyed along the extension direction of the crushed portion 77.

[0043] In the eighth embodiment of the present invention, as shown in FIG. 19, the inner wall surface (inner peripheral surface) of the frame 1 is recessed outward to form a force application portion 85 (i.e., the force application portion 85 is a recessed area) and a crushed portion 87. Here, the recess depth of the crushed portion 87 is greater than that of the force application portion 85. When the second optical accessory F of FIG. 1 is fitted to the frame 1, the above-mentioned force application portion 85 and the crushed portion 87 form an exposed gap between the second optical accessory F. A user can deform and break the crushed portion 87 by inserting a removal tool (e.g., a flathead screwdriver) into the gap and applying an outward force to the frame 1. It should be particularly noted that in the above structure, the force application portion 85 and the crushed portion 87 can be integrated as one unit, in other words, the force of the removal tool is not limited to being applied at the position of the force application portion 85, but can also be applied at a position corresponding to the crushed portion 87. In this case, the crushed portion 87 simultaneously performs the functions of the force application portion 85 and the crushed portion 87. Furthermore, the frame 1 includes the auxiliary crushing portion 471 shown in the fourth embodiment of FIG. 12, and the frame 1 can be broken sequentially along the extending direction of the crushing portion 87 and the auxiliary crushing portion 471.

[0044] In light of the above, as shown in FIG. 1 to FIG. 19, the crushable optical accessory adapter ring A of the present invention deals with improper fitting by reducing the thickness of the frame 1, and the user can easily separate the second optical accessory F from the frame 1 by simply applying an external force to the force application parts 15, 25, 35, 45, 55, 65, 75, 85 to produce the effect of bursting the crushed parts 17, 27, 37, 47, 57, 67, 77, 87. This can greatly improve the problem that the conventional adapter ring is difficult to break due to external force. Furthermore, the present invention provides a configuration in which the crushable optical accessory adapter ring A of the present invention can be used in both outdoor and indoor shooting environments without having to worry about the problem of not being able to remove the lens due to poor installation, since the destruction can be performed using both hands or a removal tool (including a screw tool). However, the above content is merely a preferred embodiment of the present invention, and the scope of the rights claimed by the present invention is not limited thereto. Equivalent modifications that a person skilled in the art can easily conceive based on the technical content disclosed in the present invention should also be included in the protection scope of the present invention.
