The mobile device accessory connector, mobile device housing, and mobile device accessory according to embodiments of the present invention will be further described below with reference to the accompanying drawings. The previously described and other technical aspects, features, and functions of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. It is worth noting that directional terms such as up, down, left, right, front, or rear, mentioned in the following embodiments are merely references to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and are not intended to limit the present invention. Furthermore, in the following embodiments, identical or similar components will be referenced using the same or similar reference numerals. Please refer to Figures 1 and 2. Figure 1 is a perspective schematic diagram of the first embodiment of the mobile device accessory connector according to the present invention in conjunction with a mobile device, while Figure 2 is a perspective schematic diagram of the mobile device accessory connector shown in Figure 1. The mobile device accessory connector 1A of this embodiment is suitable for use with a mobile device 2, where the mobile device 2 is, for example, a smartphone. However, in other possible embodiments, the mobile device 2 may also be a portable electronic device such as a smartwatch, tablet computer, personal digital assistant, digital camera, or handheld game console, and the present invention is not limited thereto. Furthermore, the mobile device accessory connector 1A includes a first connector 100A and a second connector 200A, wherein the second connector 200A is movably connected to the first connector 100A. The second connector 200A can selectively be positioned between a first position and a second position relative to the first connector 100A. Specifically, in this embodiment, the first connecting member 100A and the second connecting member 200AM are annular. The first connecting member 100A includes an outer ring portion 110A that surrounds and forms a first receiving hole 160A. The second connecting member 200A includes an inner ring portion 210A that surrounds and forms a second receiving hole 260A. The diameter of the first receiving hole 160A is greater than or equal to the outer diameter of the inner ring portion 210A. Furthermore, the second connecting member 200A further includes a pivoting portion 230A. The pivoting portion 230A can be a protrusion having substantially the same thickness as the inner ring portion 210A, disposed on the outer edge of the inner ring portion 210A and projecting radially outward from the inner ring portion 210A. The first connecting member 100A may be provided with a clearance gap 170A to accommodate the pivot portion 230A of the second connecting member 200A. In this embodiment, the outer ring portion 110A may be formed into a C-shaped ring to form the aforementioned clearance gap 170A between the head and tail ends of the C-shaped ring. Through this configuration, the second connecting member 200A is pivotally connected to the outer ring portion 110A via the pivot portion 230A. When the second connecting member 200A is in the first position relative to the first connecting member 100A, that is, the position where the second connecting member 200A is retracted relative to the first connecting member 100A, the second connecting member 200A can be accommodated in the first accommodating hole 160A and the clearance gap 170A. In some possible embodiments, the thickness of the inner ring portion 210A and the pivot portion 230A is substantially less than or equal to the thickness of the outer ring portion 110A. Thus, when the second connecting member 200A is in the retracted position, The end projection of the second connecting member 200A in the axial direction D of the outer ring portion 110A is located within the end projection of the outer ring portion 110A in the axial direction D, and the projection width of the second connecting member 200A is less than or equal to the projection width of the outer ring portion 110A. In other words, the second connecting member 200A can be stored within the first connecting member 100A. Furthermore, the mobile device accessory connector 1A is adapted to be detachably coupled to the mobile device 2, thereby making it easier for the user to remove and use the mobile device 2. As shown in Figures 1 and 2, one of the first connecting member 100A and the second connecting member 200A has at least a device coupling portion. In this embodiment, the first connecting member 100A is provided with a device coupling portion 120A, which is a magnet having a shape and size corresponding to the outer ring portion 110A.Furthermore, as shown in FIG2 , the outer ring portion 110A may be formed with at least one magnet receiving groove 116A, wherein the size and number of the magnet receiving groove 116A correspond to the magnets. The magnets are disposed in the magnet receiving groove 116A, so that the orthographic projection of the magnets in the axial direction D of the outer ring portion 110A is located within the orthographic projection of the first connecting member 100A in the axial direction D. In other words, the magnets are substantially thinner than or of equal width to the outer ring portion 110A. With this arrangement, the device coupling portion 120A can be housed within the outer ring portion 110A. When the user needs to remove or use the mobile device 2, the first connecting member 100A can be attached to the surface of the mobile device 2, so that the device coupling portion 120A aligns with the magnetic attraction feature of the mobile device 2 (for example, the MAGSAFE magnet array configured in a Dingli Energy mobile phone), thereby temporarily coupling the first connecting member 100A to the mobile device 2. At this time, The user can further adjust the second connecting member 200A to a second position relative to the first connecting member 100A, that is, when the second connecting member 200A is unfolded relative to the first connecting member 100A, the inner ring portion 210A can be pivoted to the outside of the first connecting member 100A and the first receiving hole 160A through the pivotal relationship with the outer ring portion 110A, and form a non-zero angle with the outer ring portion 110A. In some preferred embodiments, the aperture of the second receiving hole 260A is greater than or equal to the width of the user's finger, so the user can insert the finger into the second receiving hole 260A of the unfolded second connecting member 200A, and use the mobile device accessory connector 1A as a ring holder, which is quite simple and convenient. It is worth mentioning that the method of combining the first connecting member 100A with the mobile device 2 is not limited to magnetic attraction. In some possible embodiments, the device coupling portion 120A can also be a sticky foam or double-sided tape. The mobile device accessory connector 1A is adapted to be attached to the mobile device 2 or the mobile device housing for accommodating the mobile device 2 via the device coupling portion 120A. Thus, when a user wishes to remove or use the mobile device 2, they can attach the device coupling portion 120A to the surface of the mobile device 2. When finished, the two can be separated, similarly achieving a detachable connection. Alternatively, in some possible embodiments, the mobile device 2 or the mobile device housing may be formed with a groove or recessed portion adapted to engage with an external object, and the device coupling portion 120A may be a corresponding engaging protrusion or slot. The mobile device accessory connector 1A is adapted to be engaged with the mobile device 2 or the mobile device housing via the device coupling portion 120A, thereby achieving a similar effect. Since the specific details will be described in further detail in other embodiments below, they will not be elaborated upon here.It should be noted that in other possible embodiments, the device coupling portion 120A may also be provided on the second connecting member 200A, or the internal and external configuration relationships of the first connecting member 100A and the second connecting member 200A may be swapped with each other, that is, the aperture of the first receiving hole 160A may be set to be greater than or equal to the width of the user's finger, and the function of extracting the mobile device 2 is achieved by inserting the finger into the first receiving hole 160A of the first connecting member 100A that is extended relative to the second connecting member 200A. The present invention is not limited to this. Please refer to Figures 3 and 4, wherein Figure 3 is a three-dimensional schematic diagram of the mobile device accessory connector of Figure 2 and the first embodiment of the mobile device accessory of the present invention working together, and Figure 4 is a three-dimensional schematic diagram of the mobile device accessory in Figure 3 from another perspective. Specifically, the mobile device accessory connector 1A of this embodiment is also suitable for being detachably coupled with the mobile device accessory 3A, so that users can more conveniently carry and use various peripheral accessories. As shown in Figure 3, One of the first connector 100A and the second connector 200A has at least one accessory latch. In this embodiment, the second connector 200A is formed with four accessory latches 220A, each of which is a snap-fitting groove. Meanwhile, the mobile device accessory 3A is, for example, a decorative cover and includes a latch 31A, wherein the latch 31A includes at least a connector latch 33A. In this embodiment, the latch 31A includes four connector latches 33A, each of which is a snap-fitting protrusion with a shape and size corresponding to the accessory latch 220A. Thus, when a user wishes to carry or use the mobile device accessory 3A, they can engage the connector latch 33A of the mobile device accessory 3A with the accessory latch 220A of the second connector 200A, thereby removably engaging the mobile device accessory 3A with the mobile device accessory connector 1A. As shown in Figures 3 and 4, The latching member 31A of this embodiment also includes a latching body 32A. The latching body 32A is, for example, a thin, circular cover and comprises only a front side 321A, a rear side 322A, and an outer peripheral surface 323A. The front side 321A and the rear side 322A face each other, and the outer peripheral surface 323A is disposed along the circumference of the latching body 32A on the periphery of the rear side 322A. The connector latching portions 33A are circumferentially spaced apart on the outer peripheral surface 323A. Furthermore, the four accessory latching portions 220A of the second connector 200A are also circumferentially spaced apart on the inner edge of the inner ring portion 210A.Through this configuration, the evenly spaced accessory latches 220A evenly distribute the forces generated during assembly or disassembly of the mobile device accessory 3A, preventing localized force from acting on specific locations of the accessory latches 220A or connector latches 33A, thereby reducing the chance of breakage of the second connector 200A or connector latches 33A. When the mobile device accessory 3A and the second connector 200A are engaged, the front side 321A of the latch body 32A covers the second receiving hole 260A. Therefore, in some possible embodiments, the front side 321A can be decorated with colors, patterns, or various other cute designs to enhance the visual aesthetic and recognition of the mobile device accessory 3A. In some other embodiments, the accessory latch portion 220A may be disposed on the outer edge of the inner ring portion 210A, while the connector latch portion 33A is correspondingly disposed on the inner circumferential surface 324A of the latch body 32A. When the mobile device accessory 3A and the first connector 200A are engaged with each other and the second connector 200A is in the "first position," the peripheral wall of the latch body 32A may fit into the gap formed between the outer ring portion 110A and the inner ring portion 210A, thereby more significantly shielding the first accommodating hole 160A and the second accommodating hole 260A. As shown in FIG. 4 , the rear side surface 322A and the inner circumferential surface 324A of the latch body 32A may surround and form a accommodating groove.

[0056] 326A. Thus, users can place small items such as coins, tokens, inductive cards, or notes in the accommodating slot 326A. When the second connecting member 200A is in the first position, these small items are restrained by the rear side surface 322A, the inner circumferential surface 324A, and the back of the mobile device 2. When the second connecting member 200A pivots relative to the first connecting member 100A to the second position, the small items in the accommodating slot 326A are automatically displayed as the mobile device accessory 3A flips over, allowing the mobile device accessory 3A to function as a small storage container. Furthermore, the mobile device accessory connector 1A of this embodiment is suitable for coupling with the mobile device 2 and the mobile device accessory 3A from two different orientations. Please refer to Figure 5, which is a schematic cross-sectional view taken along line AA in Figure 2. As shown, the first connector 100A may further include a pivot member 130A. The pivot member 130A, for example, is a latch that extends through a pivot portion 230A received within the clearance gap 170A and is inserted and engaged with the outer ring portion 110A. This allows the second connector 200A to freely pivot relative to the first connector 100A, with the pivot angle range varying from 0 to 360 degrees, depending on user needs. Furthermore, the outer ring portion 110A has a front side 111A and a rear side 112A, wherein the front side 111A and the rear side 112A face each other. A magnet receiving groove 116A is provided on the rear side 112A. On the other hand, the inner ring portion 210A has a front side surface 211A, a rear side surface 212A, an outer peripheral surface 213A, and an inner peripheral surface 214A. The front side surface 211A and the rear side surface are opposite each other, and the outer peripheral surface 213A and the inner peripheral surface 214A are opposite each other. The accessory latch portion 220A is disposed on the inner peripheral surface 214A. Furthermore, the opening of the engaging slot formed by the accessory latch portion 220A is opened on the front side surface 211A, but the engaging slot does not pass through the rear side surface 212A. With this configuration, the mobile device accessory connector 1A is suitable for being magnetically fixed to the mobile device 2 through the rear side surface 112A of the outer ring portion 110A (the side where the device coupling portion 120A is disposed). When the first connecting member 100A is coupled to the mobile device 2, The connector latch portion 33A of the mobile device accessory 3A can enter the engagement slot via the front side 211A of the inner ring portion 210A, thereby interlocking with the accessory latch portion 220A. In other words, the user can freely select the order in which to connect the mobile device 2 and the mobile device accessory 3A, without the problem of interfering with one and preventing the other from connecting.It is worth mentioning that the mobile device accessory connector 1A of this embodiment also has the function of locking the mobile device accessory 3A along a specific direction. As shown in FIG5 , the engaging groove formed by the accessory latch portion 220A may include an alignment groove 222A and a locking groove 224A, wherein the alignment groove 222A extends from the front side surface 211A of the inner ring portion 210A along the axial direction D but does not reach the rear side surface 212A, and the locking groove 224A is arranged adjacent to the alignment groove 222A in the circumferential direction and is connected to the alignment groove 222A, and the width of the locking groove 224A in the axial direction D is smaller than the width of the alignment groove 222A in the axial direction D, that is, the locking groove 224A is not connected to the outside through the front side surface 211A or the rear side surface 212A, and the entire engaging groove is roughly in the shape of a "7" when viewed from the side. On the other hand, the circumferential length of the connector latch portion 33A is substantially equal to the circumferential length of the alignment groove 222A. Therefore, when the user wants to latch and fix the mobile device accessory 3A and the second connector 200A to each other, The connector latch portion 33A can be aligned with the alignment groove 222A to engage with the inner ring portion 210A. After the connector latch portion 33A is engaged with the inner ring portion 210A and aligned with the locking groove 224A, the latch body 32A is rotated a certain distance in the circumferential direction to engage the connector latch portion 33A within the locking groove 224A. This prevents the mobile device accessory 3A and the second connector 200A from relative displacement in the axial direction D and from detaching from the mobile device accessory connector 1A. It is worth noting that, although the alignment groove 222A extends along the front side surface 211A of the inner ring portion 210A but does not reach the rear side surface 212A in this embodiment, the present invention is not limited to this embodiment. In other embodiments, the alignment groove 222A may extend through the second connector 200A along the axial direction D, with the locking groove 224A communicating with the center portion of the alignment groove 222A, so that the entire engagement groove has a generally "-" shape when viewed from the side. Thus, the user can freely choose to insert the mobile device accessory 3A into the engagement slot from the front side 211A or the rear side 212A, thereby increasing the flexibility in the use of the mobile device accessory connector 1A.Alternatively, in another embodiment, the alignment groove 222A may extend from the rear side 212A of the inner ring portion 210A but not reach the front side 211A, such that the alignment groove 222A is open only toward the rear side 212A. With this configuration, when the first connector 100AB is attached to the mobile device 2, the second connector 200A must be unfolded to the second position relative to the first connector 100A in order to insert the mobile device accessory 3A into the engagement groove from the rear side 212A of the inner ring portion 210A for installation. Consequently, when the second connector 200A is in the first, retracted position relative to the first connector 100A, this structural configuration more effectively prevents the mobile device accessory 3A from accidentally detaching. In some possible embodiments, the first connector 100A also prevents the mobile device accessory 3A from detaching from the second connector 200A. Specifically, as shown in FIG5 , the inner circumferential surface of the outer ring portion 110A is substantially tightly coupled to the outer circumferential surface 213A of the inner ring portion 210A. However, in other embodiments, the outer ring portion 110A may also extend radially inward from the inner circumferential surface to protrude. When the second connector 200A is in the first position, the protruding portion of the outer ring portion 110A can block the opening of the engagement slot formed by the accessory latch portion 220A, thereby preventing the mobile device accessory 3A from escaping through the opening. Alternatively, in some possible embodiments, the accessory latch portion 220A and the connector latch portion 33A can function as a mutual restraint during the process of alignment and engagement. Specifically, in this embodiment, the walls of the opening of the alignment groove 222A are substantially parallel to the axial direction D. However, in other embodiments, the walls of the opening may be gradually inclined relative to the axial direction D, that is, the opening of the alignment groove 222A may be wider on the outside and narrower on the inside, or narrower on the outside and wider on the inside. With this configuration, when the second connector 200A and the mobile device accessory 3A are mated, the connector latch portion 33A needs to be slightly tilted relative to the accessory latch portion 220A along the axial direction D to ensure smooth insertion into the opening of the alignment groove 222A. This also prevents the mobile device accessory 3A from escaping from the opening. Furthermore, when the accessory latch portion 220A is a protruding engagement portion, the surface of the protruding engagement portion that engages with the groove on the mobile device accessory 3A may also be gradually tilted relative to the axial direction D. This is not further explained here. In addition, the mobile device accessory connector 1A can also utilize other methods to positionally retain the engaged mobile device accessory 3A. As shown in FIG5 , in this embodiment, the second connector 200A has only one accessory positioning portion 240A. The accessory positioning portion 240A, for example, is a positioning bump, the number of which corresponds to the number of the accessory latching portion 220A and is disposed within the engagement groove formed by the accessory latching portion 220A. Furthermore, the connector latching portion 33A is formed with a positioning feature corresponding to the accessory positioning portion 240A. In this embodiment, the positioning feature is, for example, a positioning recess. When the connector latching portion 33A is circumferentially inserted into the locking groove 224A and rotated to a specific position, the accessory positioning portion 240A and the positioning feature engage with each other, thereby circumferentially restricting the rotation of the mobile device accessory 3A relative to the second connector 200A. It is worth noting that the limiting relationship between the accessory positioning portion 240A and the positioning feature is not limited to engagement. In some possible embodiments, the accessory positioning portion 240A may also be a magnet or magnetic tape, while the positioning feature may be a corresponding magnetic member or magnetically sensitive material. The two may be magnetically retained in position, achieving the same effect. It should be noted that all of the technical features described above for the accessory latching portion 220A can also be applied to the device coupling portion 120A. Specifically, when the device coupling portion 120A is a groove or protrusion for latching onto the mobile device 2 or the mobile device housing, the device coupling portion 120A may be arranged at equal intervals to evenly distribute the forces acting between the device coupling portion 120A and the mobile device 2. Alternatively, alignment grooves, locking slots, and accessory positioning features may be provided to retain the device coupling portion 120A and the mobile device 2 in position. These features will not be further detailed here. It should also be noted that while this embodiment illustrates the device coupling portion 120A being configured on the outer ring portion 110A and the accessory latch portion 220A being configured on the inner ring portion 210A, the present invention is not limited to this configuration. In some possible embodiments, both the device coupling portion 120A and the accessory latch portion 220A may be configured on the outer ring portion 110A. In this case, at least a portion of either the mobile device accessory 3A or the mobile device housing may be coupled to the mobile device accessory connector 1A by being inserted into the first receiving hole 160A or by being latched onto the outer circumference of the outer ring portion 110A. This configuration allows the functions of coupling the mobile device 2 and latching the mobile device accessory 3A to be integrated into the first connector 100A, while the second connector 200A serves simply as a ring for extracting the mobile device 2 and mobile device accessory 3A, reducing assembly complexity.Similarly, both the device coupling portion 120A and the accessory latch portion 220A can be disposed on the inner ring portion 210A to achieve a similar effect. Please refer to Figure 6, which is a perspective schematic diagram of the mobile device accessory connector and mobile device shown in Figure 1 interacting with the second embodiment of the mobile device accessory of the present invention. The mobile device accessory 3B of this embodiment includes a latch member 31B, wherein the latch member 31B comprises a latch body 32B and at least a connector latch portion 33B. In this embodiment, the latch member 31B includes four connector latch portions 33B, each of which is a protruding engagement portion disposed at equal intervals along the circumference of the latch body 32B on the outer circumferential surface 323B of the latch body 32B. The main difference from the mobile device accessory 3A is that the latch body 32B is formed with a communication component accommodating groove 326B, which is suitable for accommodating a communication component 34B. Specifically, when a user needs to make mobile payments, access control cards, or use public transportation, a communication component 34B, such as a near-field communication (NFC) chip with credit card payment functionality, an access control card, or a radio-frequency identification (RFID) chip with EasyCard sensing functionality, can be placed in the communication component receiving slot 326B. This allows the user to easily carry both the mobile device 2 and the communication component 34B with the aforementioned functions by engaging the mobile device accessory 3B with the second connector 200A, thereby achieving convenient payment and easy sensing. In this embodiment, the communication component accommodating groove 326B is formed on the side surface 321B of the latch body 32B. In this case, the mobile device accessory 3B may further include a cover (not shown), wherein the cover is, for example, a sheet-like member having a shape and size corresponding to the communication component accommodating groove 326B. After the user arranges the communication component 34B in the communication component accommodating groove 326B, the cover can be snapped onto the opening of the communication component accommodating groove 326B to cover the communication component 34B, thereby preventing the communication component 34B from falling out of the opening of the communication component accommodating groove 326B.In other possible embodiments, the mobile device accessory 3B may not include a cover, but instead may have a communication component receiving slot 326B located on the rear side opposite the front side 321B. When the second connector 200A is retracted to the first position, the communication component 34B is simultaneously held by the rear side of the latch body 32B and the back of the mobile device 2, thereby preventing the communication component 34B from being separated from the mobile device accessory connector 1A. In some possible embodiments, the latch body 32B may also have communication component receiving slots 326B formed on both the front side 321B and the rear side 321B. The user can then select different communication components 34B to be respectively placed in the communication component receiving slots 326B on the front side 321B and the rear side, thereby enabling the mobile device accessory 3B to have a variety of payment and sensing functions. Please refer to FIG7 , which is a perspective diagram illustrating the mobile device accessory connector and mobile device shown in FIG1 in cooperation with the third embodiment of the mobile device accessory of the present invention. The mobile device accessory 3C of this embodiment includes a latch member 31C, wherein the latch member 31C includes a latch body 32C and at least a connector latch portion 33C. In this embodiment, the latch member 31C includes four connector latch portions 33C, and these connector latch portions 33C are arranged at equal intervals along the circumference of the latch body 32C, as illustrated in FIG. The main difference from the mobile device accessory 3A is that the mobile device accessory 3C also includes an accessory body 34C, wherein the accessory body 34C is a flat decorative component connected to the latch member 31C. Specifically, although the main technical features of the accessories are disposed on the latch member in the embodiments of the mobile device accessories 3A and 3B, the present invention is not limited to this. In this embodiment, the mobile device accessory 3C also includes an accessory body 34C, wherein the accessory body 34C is, for example, a flat decorative component or decorative cover having an outer diameter substantially equal to that of the outer ring portion 110A. The latching member 31C is positioned in the center of the accessory body 34C. In this embodiment, the two are secured to each other. With this arrangement, when the mobile device accessory 3C is engaged with the second connector 200A via the connector latching portion 33C, the accessory body 34C completely covers the first connector 100A, creating a unique visual effect. Furthermore, the surface of the accessory body 34C away from the latching member 31C can be printed with various patterns, colors, or desired designs, enhancing the aesthetics and recognition of the mobile device accessory 3C.In some possible embodiments, the accessory body 34C can be made of a magnetic material such as a magnet. Thus, when the mobile device accessory 3C is engaged with the second connector 200A via the connector latch portion 33C, the mobile device 2 can be magnetically secured to a magnetically sensitive structure such as a refrigerator, blackboard, or fitness equipment via the mobile device accessory connector 1A and the accessory body 34C, thereby increasing the versatility of mobile device 2. Please refer to FIG8 , which is a perspective diagram illustrating the mobile device accessory connector and mobile device shown in FIG1 in conjunction with a fourth embodiment of the mobile device accessory of the present invention. The mobile device accessory 3D of this embodiment is substantially similar to the mobile device accessory 3C of the second embodiment, comprising a latching member 31D and an accessory body 34D. The latching member 31D comprises a latching body 32D and at least a connector latching portion 33D. In this embodiment, the latching member 31D includes four connector latching portions 33D, each of which is a protruding engaging portion arranged at equal intervals along the circumference of the latching body 32D on the outer circumferential surface 323D of the latching body 32D. The main difference between the connection of the accessory body 34D to the latching member 31D and the mobile device accessory 3C is that the accessory body 34D is a ferrule. Specifically, the accessory body 34D can be a ferrule made of leather or plastic and has a latching slot 346D formed therein. The latching member 31D is disposed on a connecting surface 342D of the accessory body 34D, distal from the latching slot 346D. With this configuration, users can place ID cards, business cards, credit cards, or EasyCards into card slot 346D. By connecting accessory body 34D to mobile device accessory connector 1A via connector latch 33D, users can simultaneously access and carry mobile device 2 and various cards, providing exceptional convenience. Please refer to FIG9 , which is a perspective diagram illustrating the mobile device accessory connector and mobile device shown in FIG1 , in conjunction with the fifth embodiment of the mobile device accessory of the present invention. The mobile device accessory 3E of this embodiment is generally similar to the mobile device accessory 3C of the second embodiment, comprising a latching member 31E and an accessory body 34E. The latching member 31E comprises a latching body 32E and at least a connector latching portion 33E. In this embodiment, the latching member 31E comprises four connector latching portions 33E, each of which is a protruding engagement portion evenly spaced along the circumference of the latching body 32E and arranged on the outer circumferential surface 323E of the latching body 32E. The accessory body 34E is connected to the latching member 31E. The main difference from the mobile device accessory 3C is that the accessory body 34E is a power bank.Specifically, the accessory body 34E can be a portable power bank suitable for providing power to the mobile device 2, and the latching member 31E is disposed on the connecting surface 342E of the accessory body 34E. This arrangement allows users to simultaneously extract and carry the mobile device 2 and the mobile device accessory 3E, which includes a power bank, via the mobile device accessory connector 1A, thereby reducing the risk of the mobile device 2 suddenly running out of power. It is worth noting that in the embodiment of the mobile device accessory 3D / 3E, when the latching member 31D / 31E and the second connector 200A are engaged, the connecting surface 342D / 342E adheres to the surface of the first connector 100A. This creates a gap between the portion of the connecting surface 342D / 342E covering the first connector 100A and the back of the mobile device 2, making it easier for users to extract the mobile device 2 or the mobile device accessory 3D / 3E. However, in some other embodiments, a connection member avoidance groove (not shown) having an outer diameter and a depth corresponding to those of the outer ring portion 110A may also be formed on the connection surface 342D / the connection surface 342E. Thus, when the mobile device accessory 3D / 3E is connected to the mobile device 2 or the mobile device housing accommodating the mobile device 2 via the mobile device accessory connector 1A, the first connector 100A and the second connector 200A can be completely accommodated in the connector recess, and the connecting surface 342D / 342E can directly abut the back of the mobile device 2 or the mobile device housing. This improves the fit between the mobile device accessory 3D / 3E and the mobile device 2. Please refer to FIG10 , which is a perspective schematic diagram of the mobile device accessory connector and mobile device in FIG1 , in cooperation with the sixth embodiment of the mobile device accessory of the present invention. The mobile device accessory 3F of this embodiment is substantially similar to the mobile device accessory 3C of the third embodiment, and includes a latch 31F and an accessory body 34F. The latch 31F includes a latch body 32F and at least a connector latch portion 33F. In this embodiment, the latching member 31F includes four connecting member latching portions 33F, which are engaging protrusions on the outer peripheral surface 323F of the latching body 32F, arranged at equal intervals along the circumference of the latching body 32F. The accessory body 34F is connected to the latching member 31F. The main difference from the mobile device accessory 3C is that the accessory body 34F is a clamp.Specifically, the accessory body 34F can be a clamp that selectively opens and closes to hold an object, while the latch 31F is fixed to the accessory body 34F. With this configuration, the user can use the mobile device accessory 3F to hold the mobile device 2 in a pocket, backpack, or air conditioner vent, freeing up both hands and providing greater freedom of movement. Furthermore, in some possible embodiments, the accessory body 34F can also function as a mirror, allowing the user to review their appearance or touch up their makeup. Please refer to FIG11 , which is a perspective schematic diagram of the mobile device accessory connector and mobile device shown in FIG1 , in conjunction with the seventh embodiment of the mobile device accessory of the present invention. The mobile device accessory 3G of this embodiment is substantially similar to the mobile device accessory 3C of the third embodiment, and includes a latch 31G and an accessory body 34G. The latch 31G includes a latch body 32G and at least a connector latch portion 33G. In this embodiment, the latch 31G includes four connector latch portions 33G, each of which has a plurality of latch portions. For illustration, the engaging protrusions on the outer circumferential surface 323G of the latch body 32G are arranged at equal intervals along the circumference of the latch body 32G. The accessory body 34G is connected to the latch member 31Go. The main difference between the accessory body 34G and the mobile device accessory 3C is that the accessory body 34G is a wristband. Specifically, the accessory body 34G can be a wristband or headband sized to fit the wrist or head, with the latch member 31G secured to the accessory body 34G. With this arrangement, the user can wear the mobile device 2 on their wrist or head using the mobile device accessory 3F, achieving a similar effect as the mobile device accessory 3F. It is worth noting that the present invention is not limited to the type of accessory body 34G. In some possible embodiments, the accessory body 34G may comprise two separate straps connected by Velcro, or an elastic nylon strap, for example. Please refer to Figure 12, which is a three-dimensional schematic diagram of the mobile device accessory connector shown in Figure 1, a mobile device, and the eighth embodiment of the mobile device accessory of the present invention. The mobile device accessory 3H of this embodiment is substantially similar to the mobile device accessory 3C of the second embodiment, and includes a latch member 31H and an accessory body 34H. The latch member 31H includes a latch body 32H and at least a connector latch portion 33H. In this embodiment, the latch member 31H includes four connector latch portions 33H, each of which is a circumferentially spaced engaging protrusion disposed on the outer circumferential surface 323H of the latch body 32H. The accessory body 34H is connected to the latch member 31H.The main difference between the accessory 34H and the mobile device accessory 3C is that the accessory 34H is a stand. Specifically, the accessory body 34H can be a stand or tripod suitable for placement on a table or the floor. The latch 31H is fixed to the accessory body 34H. With this configuration, when the mobile device 2 is secured to the mobile device accessory 3H via the mobile device accessory connector 1A, it can be supported by a desktop stand or tripod, enabling the viewing of videos or automatic photography. Furthermore, in some possible embodiments, the latch body 32H and the accessory body 34H can be connected via a ball joint or other means. This allows the user to freely adjust the viewing or use angle of the mobile device 2 when the mobile device 2 is mounted on the mobile device accessory 3H. Alternatively, in some possible embodiments, the mobile device accessory 3H can include a charging coil or a built-in power supply, allowing the mobile device 2 to be charged simultaneously when mounted. The charging method can be wired or wireless, but this is not limited by the present invention. Please refer to Figures 13 and 14. Figure 13 is a perspective schematic diagram of the second embodiment of the mobile device accessory connector of the present invention, cooperating with the mobile device accessory and auxiliary accessory in Figure 3, while Figure 14 is a perspective schematic diagram of the mobile device accessory connector in Figure 13. The mobile device accessory connector 1B of this embodiment is substantially similar to the mobile device accessory connector 1A, comprising a first connector 100B and a second connector 200B. The first connector 100B has at least a device coupling portion 120B disposed on an outer ring portion 110B, while the second connector 200B has only a pivoting portion 230B secured to an inner ring portion 210B. Specifically, the outer ring portion 110B surrounds a first receiving hole 160B, while the inner ring portion 210B surrounds a second receiving hole 260B. The outer ring portion 110B further defines a clearance gap 170B to accommodate the pivoting portion 230B of the second connector 200B. In this embodiment, The first connecting member 100A may further include a pivot member 130B, such as a latch pin, which extends through a pivot portion 230B located within the clearance gap 170B and is engaged with the outer ring portion 110B, allowing the second connecting member 200B to pivot relative to the first connecting member 100B. The second connecting member 200B may also include at least one accessory latch portion 220B disposed on the inner ring portion 210B.The main difference between the mobile device accessory connector 1B and the mobile device accessory connector 1A is that one of the first connector 100B and the second connector 200B may have at least an auxiliary accessory latch portion, and the mobile device accessory connector 1B is suitable for "detachably latching" the auxiliary accessory 4 through the auxiliary accessory latch portion. For example, this embodiment chooses to provide the auxiliary accessory latch portion on the first connector 100B; the first connector 100B of this embodiment may include four auxiliary accessory latch portions 140B, and these auxiliary accessory latch portions 140B are, for example, latching grooves arranged at equal intervals along the inner circumference of the outer ring portion 110B. On the other hand, the auxiliary accessory 4 is, for example, a decorative cover and includes an auxiliary accessory body 41 and at least an auxiliary connector latch portion 42, wherein the auxiliary accessory body 41 has a front side surface 411 and an outer peripheral surface 413, and the auxiliary connector latch portion 42 is, for example, a latching protrusion corresponding in number and shape to the auxiliary accessory latch portion 140B and arranged along the auxiliary accessory body 41 The components are arranged at equal intervals along the circumference of the outer surface 413. With this arrangement, the user can simultaneously engage the auxiliary accessory 4 and the mobile device accessory 3A via the first connector 100B and the second connector 200B of the mobile device accessory connector 1B, and then magnetically secure them to the mobile device 2 via the device coupling portion 120B. Alternatively, the user can engage the auxiliary accessory 4 onto the first connector 100B while the first connector 100B is already engaged with the mobile device 2. In other words, the mobile device accessory connector 1B of this embodiment allows the user to engage two different accessories simultaneously without restricting the order of engagement or engagement, thereby providing greater flexibility in use. It is worth noting that the engagement slot formed by the accessory engaging portion 220B of the second connector 200B of this embodiment can be the aforementioned type that is open only toward the rear. This requires the second connector 200B to be unfolded to the second position relative to the first connector 100B in order to engage the mobile device accessory 3A from the inner ring portion 210B. The rear side of the second connector 200B engages with the engagement groove to complete installation. Accordingly, when the second connector 200B is in the retracted first position relative to the first connector 100B, this structural configuration effectively prevents accidental detachment of the mobile device accessory 3A. Furthermore, to ensure smooth engagement of the auxiliary accessory 4 with the first connector 100B without interference with the second connector 200B, the second connector 200B of this embodiment may further include a clearance groove 250B on the outer periphery of the inner ring portion 210B. In this embodiment, the clearance groove 250B is preferably provided on the pivot portion 230B, but this is not limiting.With this configuration, as shown in FIG14 , when the second connector 200B is in the retracted first position relative to the first connector 100B, the outer circumference of the inner ring portion 210B is spaced apart from the inner circumference of the outer ring portion 110B and, together with the clearance groove 250B, forms an annular groove, allowing the auxiliary accessory 4 to smoothly penetrate through the outer circumference 413 of the auxiliary accessory body 41 and engage with the auxiliary accessory engaging portion 140B of the first connector 100B via the auxiliary connector engaging portion 42. Referring again to FIG13 , in some possible embodiments, the accessory engaging portion 220B may be alternatively provided on the first connector 100B, for example, on the outer circumference of the outer ring portion 110B, and the mobile device accessory 3A may have a corresponding type of engaging structure, enabling the first connector 100B to simultaneously engage with two different accessories, while the second connector 200B functions as a simple ring. Alternatively, the auxiliary accessory latching portion 140B can be relocated to the second connector 200B, for example, on the outer circumference of the inner ring portion 210B, and the auxiliary accessory 4 can have a corresponding latching structure, allowing the second connector 200B to simultaneously engage with two different accessories. Please refer to FIG15 , which is a schematic cross-sectional view of the first connector along line BB in FIG14 . Similar to the accessory latch portion 220A, in this embodiment, the auxiliary accessory latch portion 140B is a latching groove and includes an alignment groove 142B and a locking groove 144B, wherein the alignment groove 142B extends from the front side 111B of the outer ring portion 110B along the axial direction D but does not reach the rear side 112B, and the locking groove 144B is arranged adjacent to the alignment groove 142B in the circumferential direction and is connected to the alignment groove 142B, and the width of the locking groove 144B in the axial direction D is smaller than the width of the alignment groove 142B in the axial direction D, that is, the locking groove 144B is not connected to the outside through the front side 111B or the rear side 112B, and the entire latching groove is roughly "7"-shaped when viewed from the side.On the other hand, the circumferential length of the auxiliary connector latch portion 42 is substantially equal to the circumferential length of the alignment groove 142B. Therefore, when the user wishes to latch and secure the auxiliary accessory 4 and the first connector 100B, the user can align the auxiliary connector latch portion 42 with the alignment groove 142B to engage the outer ring portion 110B. After the auxiliary connector latch portion 42 is engaged with the outer ring portion 110B and aligned with the locking groove 144B, the auxiliary accessory body 41 is rotated circumferentially a certain distance to engage the auxiliary connector latch portion 42 within the locking groove 144B. This prevents the auxiliary accessory 4 and the first connector 100B from relative displacement in the axial direction D and detachment from the mobile device accessory connector 1B. Preferably, the first connector 100B further comprises at least one auxiliary accessory positioning portion 150B. The auxiliary accessory positioning portions 150B are, for example, positioning protrusions, corresponding in number to the auxiliary connector latching portions 42 and disposed within the engaging groove formed by the auxiliary accessory latching portion 140B. Furthermore, the auxiliary connector latching portion 42 is formed with a positioning feature corresponding to the auxiliary accessory positioning portion 150B. In this embodiment, the positioning feature is a positioning recess. When the auxiliary connector latching portion 42 is circumferentially engaged with the locking groove 144B and rotated to a specific position, the auxiliary accessory positioning portion 150B and the positioning feature engage with each other, thereby circumferentially restricting rotation of the auxiliary accessory 4 relative to the first connector 100B. Please refer to Figure 16, which is a perspective schematic diagram of the third embodiment of the mobile device accessory connector of the present invention, the first embodiment of the mobile device housing of the present invention, and the mobile device. The mobile device accessory connector 1C of this embodiment is substantially similar to the mobile device accessory connector 1A of the first embodiment, comprising a first connector 100C and a second connector 200C. The first connector 100C includes an outer ring portion 110C and at least a device-engaging portion 120C. The device-engaging portion 120C is configured as the outer ring portion 110C, while the second connector 200C is pivotally connected to the outer ring portion 110C. The primary difference between the mobile device accessory connector 1C and the mobile device accessory connector 1A is that the device-engaging portion 120C is a latching protrusion, and the mobile device accessory connector 1C is adapted to cooperate with the mobile device housing 5A housing the mobile device 2. Specifically, the outer ring portion 110C has an outer peripheral surface, and the device-engaging portions 120C are, for example, latching protrusions disposed on the outer peripheral surface at equal intervals along the circumference of the outer ring portion 110C.On the other hand, the mobile device housing 5A of this embodiment includes a housing body 51A and a connector coupling portion 52A, wherein the housing body 51A is suitable for accommodating the mobile device 2; and the connector coupling portion 52A is disposed on the housing body 51A and is suitable for detachably coupling with the device coupling portion 120C of the mobile device accessory connector 1C. Furthermore, the housing body 51A may have a back side, and the connector coupling portion 52A may be, for example, a back plate formed with a connector receiving groove 526A and disposed on the back side of the housing body 51A, wherein the connector receiving groove 526A may be, for example, a through groove penetrating the back side of the housing body 51A, and a locking groove having a shape and number corresponding to the device coupling portion 120C is formed on the groove wall of the through groove. Through such a configuration, the user may first accommodate the mobile device 2 in the mobile device housing 5A, and then couple the first connector 100C with the connector coupling portion 52A through the device coupling portion 120C, so that the connector receiving groove 526A accommodates at least a portion of the first connector 100C and is locked and fixed. Therefore, the user may use the second connector 200C as a ring for extracting the mobile device 2 and the mobile device housing 5A, thereby conveniently and easily carrying it. It is worth mentioning that in some other embodiments, The device coupling portion 120C can also be configured on the second connector 200C. In this case, the connector receiving groove 526A can be designed as a groove corresponding to the size of the second connector 200C, thereby accommodating at least a portion of the second connector 200C. Alternatively, in other embodiments, the connector coupling portion 52A may include an auxiliary receiving groove (not shown) in addition to the connector receiving groove 526A, and the auxiliary receiving groove is adapted to accommodate the other of the first connector 100C and the second connector 200C. With this configuration, the mobile device housing 5A can simultaneously accommodate at least a portion of both the first connector 100C and the second connector 200C through the connector receiving groove 526A and the auxiliary receiving groove, respectively. Users can choose to use either the first connector 100C or the second connector 200C as a ring, while engaging the other with the mobile device housing 5A. Please refer to FIG. 17 . FIG. 17 is a perspective schematic diagram of the mobile device accessory connector in FIG. 16 cooperating with the second embodiment of the mobile device housing of the present invention and the mobile device.The mobile device case 5B of this embodiment is substantially similar to the mobile device case 5A of the first embodiment, comprising a case body 51B and a connector coupling portion 52B. The case body 51B is adapted to accommodate the mobile device 2, while the connector coupling portion 52B is located on the back side of the case body 51B and defines a connector receiving groove 526B. The primary difference from the mobile device case 5A is that the connector receiving groove 526B does not extend through the back side of the case body 51B. Specifically, in this embodiment, the connector receiving groove 526B is recessed only relative to the case body 51BPH, and the depth of the connector receiving groove 526B is substantially equal to the thickness of the first connector 100C. This arrangement allows the user to insert the mobile device accessory connector 1C into the connector receiving groove 526B without protruding from the mobile device case 5B, allowing the user to unfold the second connector 200C to its second position, allowing it to function as a ring. It should be noted that When the mobile device accessory connector 1C is inserted into the connector receiving slot 526B, the rear sides of the first connector 100C and the second connector 200C adhere to the bottom wall of the connector receiving slot 526B. Therefore, in some possible embodiments, the device coupling portion 120C can be replaced with a magnet or adhesive foam, while the connector coupling portion 52B can be a corresponding magnetic member or adhesive surface, thereby bonding the bottom wall of the connector receiving slot 526B to each other. Alternatively, in addition to the locking relationship between the device coupling portion 120C and the peripheral edge of the slot wall, additional fixing methods such as magnetic attraction or adhesion can be added to further enhance the bonding strength between the mobile device accessory connector 1C and the mobile device housing 5B. Please refer to Figure 18, which is a perspective schematic diagram of a fourth embodiment of the mobile device accessory connector of the present invention. The mobile device accessory connector 1D of this embodiment is substantially similar to the mobile device accessory connector 1B of the second embodiment, and includes a first connector 100D and a second connector 200D. The first connecting member 100D includes an outer ring portion 110D, at least a device coupling portion (not shown), a pivoting member 130D, and at least an accessory latching member 140D. The outer ring portion 110D surrounds and forms a first receiving hole 160D. The device coupling portion, for example, is a magnet and is disposed on the outer ring portion 110D. The pivoting member 130D is connected to the outer ring portion 110D. The accessory latching member 140D, for example, comprises a plurality of engaging grooves disposed along the circumference of the outer ring portion 110D and formed on the inner circumferential surface of the outer ring portion 110D.On the other hand, the second connecting member 200D includes an inner ring portion 210D, at least one accessory latch portion 220D, and a pivot portion 230D. The inner ring portion 210D surrounds a second receiving hole 260D. The accessory latch portion 220D is, for example, a plurality of engaging grooves disposed along the circumference of the inner ring portion 210D on its inner circumference. The pivot portion 230D is fixed to the outer circumference of the inner ring portion 210D. The first connecting member 100D and the second connecting member 200D are pivotally connected to each other via the pivot portion 130D and the pivot portion 230D. The main difference from the mobile device accessory connector 1B is that the first connecting member 100D further includes a stop portion 115D disposed on the outer ring portion 110D and aligned with the pivot portion 230D. In detail, The mobile device accessory connector 1D can limit the pivoting phase or stroke of the second connecting member 200D relative to the first connecting member 100D. As shown in FIG18 , the stop portion 115D is, for example, a flat member and is disposed between the notches at the head and tail ends of the outer ring portion 110D, while the pivoting member 130D is disposed radially outward of the stop portion 115D and is pivotally connected to the pivoting portion 230D. Through such a configuration, when the second connecting member 200D is retracted to the first position relative to the first connecting member 100D, the pivoting portion 230D will abut against the upper surface of the stop portion 115D, thereby restricting the inner ring portion 210D from further pivoting toward the inside of the first accommodating hole 160D, thereby achieving the effect of limiting the pivoting phase or stroke of the second connecting member 200D. In addition, as shown in FIG18 , the accessory latch portion 220D may also include an alignment groove and a locking groove, and in this embodiment, The locking groove extends radially through the inner ring portion 210D. This allows a portion of the connector latching portion 33A to extend when the mobile device accessory connector 1D and the mobile device accessory 3A are engaged. This allows the connector latching portion 33A to extend to a length greater than or equal to the radial width of the inner ring portion 210D. This allows the connector latching portion 33A to extend beyond the inner ring portion 210D when in its extended position, thereby enhancing the stability of the engagement. Please refer to Figure 19, which is a perspective diagram illustrating the cooperative interaction between the fifth embodiment of the mobile device accessory connector and the ninth embodiment of the mobile device accessory.The mobile device accessory connector 1E of this embodiment includes a connector 100E, wherein the connector 100E includes a connector body 110E, at least a device coupling portion 120E, and at least one accessory latch portion 140E. The connector body 110E is surrounded by a receiving hole 160E. The device coupling portion 120E and the accessory latch portion 140E are configured as a "connector body 110E." The mobile device accessory connector 1E can be detachably connected to the mobile device 2 and latched to the mobile device accessory 31 through the device coupling portion 120E and the accessory latch portion 140E, respectively. Specifically, in this embodiment, the device coupling portion 120E is, for example, a C-shaped magnet, and the connector body 110E is formed with a magnet receiving groove 116E, and the device coupling portion 120E is configured in the "magnet receiving groove 116E." In addition, The accessory latching portions 140E are, for example, a plurality of engaging grooves arranged at equal intervals along the circumference of the connector body 110E on the inner circumference of the connector body 110E. Meanwhile, the mobile device accessory 31 of this embodiment is, for example, a power bank (or external power supply) and includes a latching member 311, an accessory body 341, and a magnetic member 351. The latching member 311 includes a latching member 321 and at least a connector latching portion 331. The latching member 321 is, for example, a circular disk having an outer diameter substantially the same as that of the accommodating hole 160E. The connector latching portions 331 are, for example, engaging protrusions, corresponding in number and shape to the accessory latching portions 140E and arranged at equal intervals along the circumference of the latching body 321 on the outer circumference 3231 of the latching body 321. The accessory body 341 is, for example, a disk having substantially the same outer diameter as the connector body 110E and is secured to the latch body 321. The magnetic member 351 is, for example, a C-shaped magnet having a shape and size corresponding to the device coupling portion 120E. With this configuration, when a user connects the mobile device 2 and the mobile device accessory 31 via the mobile device accessory connector 1E, the latch body 321 fits into the accommodating hole 160E, and the accessory body 341 and the connector body 110E fit snugly and flush with each other. The device coupling portion 120E not only serves as a medium for magnetically attracting the mobile device 2 to the mobile device accessory connector 1E, but also further enhances the bonding strength between the mobile device accessory connector 1E and the mobile device accessory 31 through the magnetic attraction between the device coupling portion 120E and the magnetic member 351, while also providing a secure connection between the accessory latch portion 140E and the connector latch portion 331.It's worth noting that in other possible embodiments, the mobile device accessory 31 may not have the latch body 321 protruding from the end surface of the accessory body 341. Instead, the connector latch portion 331 may be located on the end surface of the accessory body 341. The connector latch portion 331 may be a groove having substantially the same shape and size as the connector body 110E. In this manner, the connector body 110E can be inserted into the connector latch portion 331, and the connector latch portion 331 can engage with the outer surface of the connector body 110E. Alternatively, the magnetic member 351 may be first secured to the connector latch portion 331 and then inserted into the connector body 110E. The magnetic attraction between the device coupling portion 120E and the magnetic member 351 secures the connector body 110E to the mobile device accessory 31. The present invention is not limited to this approach. Please refer to Figure 20, which is a schematic perspective view of the mobile device accessory connector and the auxiliary connector shown in Figure 19. As shown in the figure, in this embodiment, the mobile device accessory connector 1E further includes a pivotal member 130E, wherein the pivotal member 130E is pivotally connected to the connector body 110E and defines an insertion slot 136E. The mobile device accessory connector 1E is adapted to be detachably connected to the auxiliary connector 200E via the pivotal member 130E. Specifically, the auxiliary connector 200E includes an auxiliary connector body 210E and an insertion portion 230E. The auxiliary connector body 210E is generally annular and surrounds an auxiliary receiving hole 260E. The insertion portion 230E is, for example, a protrusion with a hook formed at the rear end and disposed on the outer circumferential surface 213E of the auxiliary connector body 210E. In this way, the user can pivot the pivot member 130E relative to the connector body 110E to a non-parallel position with the connector body 110E, and then insert the auxiliary connector 200E into the insertion slot 136E of the pivot member 130E via the insertion portion 230E to secure it. This allows the auxiliary connector 200E to function as a ring for removal while the connector 100E is connected to the mobile device 2 or the mobile device accessory 31. It is worth noting that, in the aforementioned embodiments having the first and second connectors, the structures and technical features of each can be applied to the connector 100E and the auxiliary connector 200E, provided that no structural or conceptual conflicts arise. Similarly, the technical feature of the auxiliary connector 200E pivotally connected to the connector body 110E via the insertion portion 230E and the pivot member 130E can also be applied to the aforementioned embodiments having the first and second connectors, without limiting the present invention.Please refer to Figure 21, which is a perspective schematic diagram illustrating the mobile device accessory connector in Figure 19 in conjunction with the tenth embodiment of the mobile device accessory of the present invention. As shown, the mobile device accessory 3J of this embodiment is, for example, a flat decorative piece and includes an accessory body 31J and a plug-in portion 32J. The accessory body 31J includes a front side 311J and an outer peripheral surface 313J, with the plug-in portion 32J disposed on the outer peripheral surface 313J. This allows users to customize the front side 311J of the mobile device accessory 3J with various colors, patterns, or other attractive designs. This enhances the overall aesthetics and recognition of the mobile device accessory 3J when the connector 100E is combined with the mobile device 2 or the mobile device housing 5B. Please refer to Figure 22, which is a perspective schematic diagram illustrating the mobile device accessory connector in Figure 19 in conjunction with the eleventh embodiment of the mobile device accessory of the present invention. As shown in the figure, the mobile device accessory 3K of this embodiment is, for example, a three-dimensional decorative piece and includes an accessory body 31K and an inserting portion 32K. The accessory body 31K includes a front side surface 311K and an outer peripheral surface 313K, and the inserting portion 32K is disposed on the outer peripheral surface 313K±. OIn this way, the user can configure colors, patterns or various cute designs on the front side 311K of the mobile device accessory 3K, so that when the connector 100E is combined with the mobile device 2 or the mobile device housing 5B, the overall aesthetics and the recognition of the mobile device accessory 3J are improved. It should be noted that the terms "flat decorative element" and "three-dimensional decorative element" herein refer to whether the front side of the accessory body protrudes relative to the connector body 110E when the inserting portion 32J / 32K is inserted into the insertion slot 136E and the pivoting member 130E pivots to a position parallel to the connector body 110E. A flat decorative element is defined when the front side 311J of the accessory body 31J is recessed relative to or flush with the connector body 110E. Conversely, a three-dimensional decorative element is defined when the front side 311K of the accessory body 31K protrudes relative to the connector body 110E. Please refer to FIG. 23 , which is a perspective schematic diagram of a sixth embodiment of the mobile device accessory connector of the present invention. The mobile device accessory connector 1F of this embodiment includes a first connector 100F and a second connector 200F. The first connector 100F includes an outer ring portion 110F, at least a device coupling portion (not shown), and at least an auxiliary accessory latch portion 140F. The outer ring portion 110F surrounds and forms a first receiving hole 160F. The device coupling portion is, for example, a magnet and is disposed on the outer ring portion HOF. The auxiliary accessory latch portion 140F is, for example, a plurality of engaging grooves evenly spaced along the circumference of the outer ring portion 110F on the inner circumference of the outer ring portion 110F. On the other hand, the second connector 200F includes an inner ring portion 210F, at least one accessory latch portion 220F, and an inserting portion 230F. The inner ring portion 210F surrounds and defines a second receiving hole 260F. The accessory latch portion 220F may be, for example, a plurality of engaging protrusions evenly spaced along the circumference of the inner ring portion 210F on an outer circumferential surface 213F of the inner ring portion 210F. The inserting portion 230F is disposed on the outer circumferential surface 213F. The main difference from other mobile device accessory connectors is that the outer ring portion 110F is formed with a plurality of connector latch slots 118F. Therefore, the second connector 200F is adapted to be selectively inserted into one of these connector latch slots 118F via the inserting portion 230F.Specifically, in this embodiment, the plug-in portion 230F is retractable and, when retracted into the outer periphery W213F of the inner ring portion 210F, allows the second connector 200F to be positioned relative to the first connector 100F by being accommodated within the first receiving hole 160F. When the user wishes to deploy the second connector 200F relative to the first connector 100F, the user first removes the second connector 200F, extends the plug-in portion 230F beyond the outer periphery 213F of the inner ring portion 210F, and then inserts the plug-in portion 230F into the connector latch groove 118F. These connector latch grooves 118F provide different insertion phases for the second connector 200F. As shown in the figure, when the plug-in portion 230F is inserted into the outermost connector latch groove 118F, the inner ring portion 210F extends radially outwardly relative to the outer ring portion 110F. When the plug-in portion 230F is inserted into the middle connector latch groove 118F, the inner ring portion 210F is perpendicular to the outer ring portion 110F. When the plug-in portion 230F is inserted into the innermost connector latch groove 118F, the inner ring portion 210F extends radially inward relative to the outer ring portion 110F. This allows the user to insert the second connector 200F into different connector latch grooves 118F, thereby adjusting the usage state and position of the second connector 200F relative to the first connector 100F. It should be noted that although in this embodiment, the connector latch grooves 118F are three parallel latch grooves extending circumferentially along the outer ring portion 110F and distributed on the same side of the outer ring portion 110F, the present invention is not limited to this. In other possible embodiments, the outer ring portion 110F may also have three latch grooves at 0 degrees, 90 degrees, and 118 degrees. Both the 180-degree and 270-degree connector latch slots 118F are provided. The number of connector latch slots 118F in each phase can be one, two, or more, thereby also achieving the function of adjusting the operating position of the second connector 200F. In other possible embodiments, the inserting portion 230F may not have a telescopic function, but may be fixedly protruded from the outer peripheral surface 213F, similar to the accessory latch portion 220F.As such, the auxiliary accessory latch portion 140F of the mobile device accessory connector 1F of this embodiment can include an additional engaging groove disposed on the inner circumference of the outer ring portion 110F for receiving the plugging portion 230F. The plugging portion 230F and the accessory latch portion 220F are preferably arranged at equal intervals along the circumference of the inner ring portion 210F. This allows the multiple engaging grooves to be correspondingly arranged at equal intervals along the circumference of the outer ring portion 110G on the inner circumference of the outer ring portion 110G. This allows the plugging portion 230F and the accessory latch portion 220F to be aligned and assembled in any of the engaging grooves, thereby improving assembly convenience and efficiency. It is worth noting that, in the drawings of the aforementioned embodiments, the first receiving hole of the first connecting member and the second receiving hole of the second connecting member are both in the form of through-holes. However, as long as there is no structural conflict, the first receiving hole and / or the second receiving hole of each embodiment may also be in the form of grooves rather than through-holes. Moreover, even if the second receiving hole of the second connecting member is not through-hole, the user can still secure the mobile device by gripping the inner ring portion of the second connecting member between two fingers. Therefore, the configurations of the first receiving hole and the second receiving hole of the first connecting member of the present invention are not limited to those shown in the drawings. Those skilled in the art may modify the design as needed. The above description is merely an embodiment of the present invention and is not intended to limit the scope of the present invention. It should be noted that all equivalent variations and substitutions to the above embodiments are considered to be within the scope of the present invention. The technical features of the above embodiments may be appropriately combined, substituted, omitted, and modified without causing any conceptual or structural conflicts.
