Description

Technical Field

[0001] This invention belongs to the field of locking technology, and in particular relates to a multi-angle locking mechanism that is easy to assemble and disassemble. Background Technology

[0002] Personalized decorative items such as plush toys, metal badges, and pendants are mostly fixed to everyday objects such as bags and electronic products through traditional installation methods such as snap-fit, glue, or magnetic connection. However, these traditional installation methods cannot guarantee the installation stability between the decorative items and the bags or other objects, and cannot achieve multi-angle display of the decorative items.

[0003] To address this, the invention patent with application number 2025107906142 proposes a lock with switchable angles. It fixes the first connecting component (referred to as the male head) to the ornament and clamps the second connecting component (referred to as the female seat) onto objects such as bags. The male head and female seat can be disassembled and assembled by the locking mouth of the male head in conjunction with the locking tongue of the locking spring. The male head can rotate around the female seat and has rotational damping by the ratchet tooth ring and pawl, ensuring that the ornament can be stably installed and displayed from multiple angles.

[0004] However, because the ratchet ring of the latch engages with the pawl and fixes the spring-loaded locking plate, and the locking tongue of the spring-loaded locking plate engages with the locking mouth of the male head to form an axial limit, the male head can only be adjusted by rotating in the forward direction and unlocked by rotating in the reverse direction. As a result, users cannot freely adjust the display angle during actual use and are prone to accidental unlocking, resulting in a poor user experience. Furthermore, rotating in the reverse direction to unlock the male head can easily damage the locking spring, ratchet ring, pawl, and other related components, leading to a short service life. Summary of the Invention

[0005] Technical problems to be solved This invention provides a multi-angle locking mechanism that is easy to assemble and disassemble. It can enable the male connector to rotate in both directions, prevent the male connector from being removed due to incorrect operation, and avoid damage to related components when unlocking the male connector.

[0006] Technical solution To achieve the above objectives, the present invention provides the following technical solution: A multi-angle locking mechanism for easy assembly and disassembly includes a female base, a male head, a circumferential fixing member, an axial locking member, and an unlocking member. The male head has a connecting post, which includes a connecting portion and a positioning portion. The circumferential fixing member is rotatably mounted within the female base and has rotational damping, and has a through hole communicating with the inside and outside of the female base. The axial locking member is mounted within the female base and positioned beside the circumferential fixing member, and is located below the through hole. The unlocking member is mounted on the female base and corresponds to the axial locking member. The connecting post extends through the through hole into the female base. The circumferential fixing member and the axial locking member connect the connecting portion and the positioning portion, respectively, to restrict the male head to be mounted on the female base and allow the male head to rotate around the female base. The unlocking member drives the axial locking member away from the positioning portion, allowing the male head to be removed from the female base.

[0007] Preferably, the connecting part is provided with a plug and the through hole is provided with a slot. When the connecting post passes through the through hole into the female part, the plug is inserted into the slot so that the circumferential fixing member connects to the connecting part, thereby ensuring that the circumferential fixing member can rotate with the male end.

[0008] Preferably, the female seat has a rotating cavity and a locking cavity inside. The locking cavity is formed inside the rotating cavity and connects to the through hole. A boss is provided at the positioning part. The circumferential fixing member is rotatably installed in the rotating cavity and has rotational damping. The axial locking member is a locking block with a spring and a locking tongue. The locking block is swayably installed in the locking cavity and abuts against the inner wall of the locking cavity and the boss through the spring and the locking tongue, respectively, so as to rotatably restrict the male head to be installed on the female seat. The unlocking member can drive the locking block to swing, so as to compress the spring, deform and store energy, and disengage the locking tongue from the boss, thereby ensuring that the male head can be removed from the female seat.

[0009] Preferably, the boss has a first inclined surface that extends downward and gradually contracts towards the center, and the latch has a second inclined surface that extends upward and gradually expands towards the center. During the process of pressing the connecting post into the through hole, the first inclined surface can squeeze the second inclined surface to drive the spring to deform and store energy. After the spring is reset, it drives the latch to abut against the boss.

[0010] Preferably, the unlocking component includes a sliding key and a pressure block. The sliding key is slidably mounted on the female seat and fixed to the pressure block. The pressure block is placed in the lock cavity and abuts against the locking block. Pressing the sliding key can drive the pressure block to cause the locking block to swing, thereby compressing the spring to deform and store energy, and causing the bolt to disengage from the boss.

[0011] Preferably, there are two locking blocks symmetrically arranged on both sides of the through hole, so that the two locking tongues can simultaneously abut against the two points of the boss, and the pressing block is located in the middle of the two locking blocks and can simultaneously abut against and drive the two locking blocks.

[0012] Preferably, the circumferential fixing member is interference-fitted with the rotating cavity to provide rotational damping, or it may further include a damping member mounted on the female seat and disposed beside the rotating cavity to provide rotational damping for the circumferential fixing member.

[0013] Preferably, the circumferential fixing member is a gear, which is rotatably mounted in the rotating cavity and has multiple tooth grooves arranged in a circumferential array. The through hole is formed at the center of the gear shaft. The damping member includes a tooth block and a spring. The tooth block is slidably mounted on the female seat and has retaining teeth. The retaining teeth are placed in the rotating cavity and mesh with the tooth grooves. The spring is disposed on the female seat and abuts against the retaining teeth and the female seat. The gear can rotate with the male head, and the retaining teeth can mesh with multiple tooth grooves one by one under the action of the spring to provide rotational damping.

[0014] Preferably, the female seat is further provided with a keyway connecting the rotating cavity, the locking cavity and the outside; the sliding key is slidably installed in the keyway, and the end of the sliding key protrudes from the keyway to the outside; the pressure block is placed in the locking cavity and abuts against the locking block; the tooth block is slidably installed in the keyway; the locking tooth is placed in the rotating cavity and meshes with the tooth groove; the spring is placed in the keyway and abuts against the tooth block and the sliding key.

[0015] Preferably, a magnetic block is also installed on the connecting column, and a magnetic block is installed at the bottom of the female seat, the magnetic block being able to attract the magnetic block accordingly.

[0016] Preferably, it further includes a mounting component disposed on the female base and used to fix the female base to a specific object.

[0017] Preferably, the mounting component is a clamping seat, one end of the female seat is hinged to the clamping seat, the other end of the female seat is provided with a buckle, and the clamping seat is provided with a fixing buckle that can engage or disengage from the buckle.

[0018] Preferably, the mounting component is a magnetic base, which is fixedly mounted on the female base, and the bottom of the magnetic base is provided with a magnetic ring, which is integrally formed or composed of multiple magnets arranged in a circular array.

[0019] Beneficial effects This invention provides a multi-angle locking mechanism that facilitates easy assembly and disassembly. By incorporating a circumferential fixing component and an axial locking component inside the female connector to respectively engage with the male connector's connecting and positioning parts, the male connector is rotatably secured to the female connector. An unlocking component on the female connector drives the axial locking component away from the positioning part, thus enabling the male connector to be disassembled. This structural design improves the ease of assembly and disassembly between the male connector and the female connector. Furthermore, since the circumferential fixing component and the axial locking component are independent, the axial locking component does not interfere with the rotation of the circumferential fixing component. This allows for both forward and reverse rotation of the male connector, prevents accidental disassembly due to incorrect operation, and avoids damage to related components during unlocking, thereby improving user experience and extending service life.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0023] See appendix Figure 1 - Appendix Figure 10 A multi-angle locking device that is easy to assemble and disassemble includes a female base 1, a male head 2, a circumferential fixing member 3, an axial locking member 4, and an unlocking member 5. The male head 2 is provided with a connecting post 20, which has a connecting part 21 and a positioning part 22. The circumferential fixing member 3 is rotatably installed in the female base 1 and has rotational damping, and the circumferential fixing member 3 is provided with a through hole 30 connecting the inside and outside of the female base 1. The axial locking member 4 is installed in the female base 1 and is located beside the circumferential fixing member 3, and the axial locking member 4 is located below the through hole 30. The unlocking member 5 is installed on the female base 1 and is provided corresponding to the axial locking member 4. The circumferential fixing member 3 and the axial locking member 4 can be connected to the connecting part 21 and the positioning part 22 respectively to rotatably restrict the male head 2 to be installed on the female base 1. The unlocking member 5 can drive the axial locking member 4 to disengage from the positioning part 22 so that the male head 2 can be removed from the female base 1.

[0024] Specifically, during assembly, the connecting post 20 of the male head 2 is inserted into the through hole 30, and the circumferential fixing member 3 is connected to the connecting part 21 to prevent the male head 2 from rotating, and the axial locking member 4 is connected to the positioning part 22 to form an axial limit to prevent the male head 2 from moving up and down, so that the male head 2 is rotatably restricted and installed on the female seat 1.

[0025] In use, the male head 2 can rotate around the female head 1 in the forward or reverse direction. Because the circumferential fixing part 3 has rotational damping, the male head 2 can stop at the current position under the action of damping after rotating a certain angle.

[0026] During disassembly, the axial locking member 4 is disengaged from the positioning part 22 by the unlocking member 5, thereby releasing the axial limit. At this time, the connecting post 20 is moved outward along the axial direction of the through hole 30, and the connecting part 21 is disengaged from the circumferential fixing member 3, so that the male head 2 can be removed from the female seat 1.

[0027] In summary, this solution uses a circumferential fixing member 3 and an axial locking member 4 inside the female seat 1 to respectively cooperate with the connecting part 21 and the positioning part 22 of the male connector 2, thereby rotatably restricting the male connector 2 to be installed on the female seat 1. By setting an unlocking member 5 on the female seat 1 to drive the axial locking member 4 to disengage from the positioning part 22, the disassembly of the male connector 2 can be completed. This structural design improves the ease of disassembly and assembly between the male connector 2 and the female seat 1. Since the circumferential fixing member 3 and the axial locking member 4 are set independently, the axial locking member 4 will not interfere with the rotation of the circumferential fixing member 3. When the circumferential fixing member 3 rotates, the axial locking member 4 can also continuously cooperate with the positioning part 22 of the connecting column 20 to restrict the male connector 2 from disengaging. Therefore, it can realize the forward and reverse rotation of the male connector 2, prevent the male connector 2 from being disassembled due to incorrect operation, and avoid damage to related components when unlocking the male connector 2, thereby improving the user experience and extending the service life.

[0028] It should be noted that in practical applications, decorative parts (not shown in the illustration) can be fixed on the male connector 2 of this lock, and the female connector 1 can be installed on specific objects (not shown in the illustration) such as bags and mobile phones. Through the cooperation of the male connector 2 and the female connector 1, the decorative parts can be quickly installed and the angle can be adjusted. In addition to the application scenarios mentioned above, this lock can also be used in some other applicable scenarios, especially on objects that need to have angle adjustment function after connection. Since the application scenarios of this lock are diverse, this invention does not limit them.

[0029] See appendix Figure 3 - Appendix Figure 9 The connecting part 21 is provided with a plug 210, and the through hole 30 is provided with a slot 300 that is adapted to the plug 210.

[0030] Specifically, when the connecting post 20 penetrates the through hole 30 into the female seat 1, the insert block 210 inserts into the slot 300 to connect the circumferential fixing member 3 with the connecting part 21, so as to provide circumferential limit for the connecting post 20, thereby enabling the circumferential fixing member 3 to rotate with the male head 2, and ensuring that the connecting post 20 can still move axially to ensure the quick installation and removal of the male head 2.

[0031] Furthermore, the slot 300 is provided with multiple slots arranged in a circular array on the inner wall of the through hole 30. The insert 210 can be inserted into any slot 300. This design allows the connecting part 21 of the connecting post 20 to be freely inserted into the through hole 30 to complete the connection with the circumferential fixing member 3, thereby improving the ease of operation.

[0032] It should be noted that, in addition to the above-mentioned structure, the connecting part 21 and the circumferential fixing part 3 can also be detachably connected by means of strong magnetic connection, snap-fit ​​connection, etc. Since there are various related connection methods, this invention does not limit them.

[0033] See appendix Figure 3 - Appendix Figure 10 The female seat 1 has a rotating cavity 11 and a locking cavity 12 inside. The locking cavity 12 is formed in the rotating cavity 11 and connected to the through hole 30. The positioning part 22 has a boss 220. The circumferential fixing member 3 is rotatably installed in the rotating cavity 11 and has rotational damping. The axial locking member 4 adopts a locking block 41 with a spring 411 and a locking tongue 412. The locking block 41 is swayably installed in the locking cavity 12 and abuts against the inner wall of the locking cavity 12 and the boss 220 through the spring 411 and the locking tongue 412 respectively. The unlocking member 5 can drive the locking block 41 to swing, so as to compress the spring 411 to deform and store energy and make the locking tongue 412 disengage from the boss 220.

[0034] Specifically, during assembly, there are two installation methods for the male connector 2. The first method involves directly pressing the male connector 2, causing the boss 220 of the connecting post 20 to enter the lock cavity 12 through the through hole 30, pressing the bolt 412 and causing the locking block 41 to swing outward. During this process, the spring 411 deforms and stores energy. After the boss 220 moves down to a specific position, the spring 411 releases energy and restores its original position, causing the locking block 41 to swing inward, so that the bolt 412 returns to its original position and abuts against the boss 220. The second method involves first driving the locking block 41 outward through the unlocking component 5. After the spring 411 deforms and stores energy and the bolt 412 moves away from the through hole 30, the connecting post 2... Insert the pin 220 into the through hole 30 and move it to the side of the latch 412. Then release the unlocking member 5 from the locking block 41. The spring 411 will release energy and restore the locking block 41, causing it to swing inward. This will allow the latch 412 to return to its original position and abut against the pin 220. Both installation methods can rotatably restrict the male head 2 to be installed on the female seat 1. The user can choose the method that best suits them. When removing the male head 2, first use the unlocking member 5 to drive the locking block 41 to swing outward, so as to compress the spring 411 to deform and store energy, and cause the latch 412 to disengage from the pin 220. This will release the axial restriction on the connecting post 20, allowing the connecting post 20 to be moved upward smoothly and the male head 2 to be removed.

[0035] In summary, by using the internal rotating cavity 11 and locking cavity 12 of the female seat 1 to install the circumferential fixing member 3 and the locking block 41 respectively, and by setting the unlocking member 5 to drive the locking block 41 independently, the male head 2 can be quickly installed and removed, and the locking tongue 412 can independently abut against or disengage from the limiting boss 220. This effectively avoids interference with the locking tongue 412 and the unlocking member 5 when the male head 2 rotates, and extends the service life of the relevant components.

[0036] It should be noted that in other embodiments, the axial locking member 4 may also be a stop block (not shown in the figure) that is slidably installed in the female seat 1. The stop block is driven to move by the unlocking member 5 to abut or disengage from the boss 220, which can also provide axial limit for the connecting column 20. Since the axial locking member 4 can be made of various types of components to achieve axial limit for the connecting column 20, this invention does not limit it.

[0037] See appendix Figure 3 - Appendix Figure 8 The boss 220 has a first inclined surface 220d that extends downward and gradually tapers toward the center, and the latch 412 has a second inclined surface 412d that extends upward and gradually expands toward the center. The first inclined surface 220d can fit against the second inclined surface 412d.

[0038] Specifically, when assembling the female connector 1 and the male connector 2, the connecting post 20 is inserted into the through hole 30 and the male connector 2 is pressed down. During the downward movement of the connecting post 20, the first inclined surface 220d can squeeze the second inclined surface 412d to open the latch 412, thereby causing the locking block 41 to swing outward and causing the spring 411 to deform and store energy. After the boss 220 continues to move downward and the first inclined surface 220d disengages from the second inclined surface 412d, the spring 411 releases energy and recovers, causing the locking block 41 to swing inward, so that the latch 412 returns to its original position and abuts against the boss 220 to form an axial limit. Therefore, the combined use of the first inclined surface 220d and the second inclined surface 412d makes it easier for the boss 220 to open the latch 412, further improving the installation convenience of the male connector 2.

[0039] See appendix Figure 3 - Appendix Figure 10 The unlocking component 5 includes a sliding key 51 and a pressure block 52. The sliding key 51 is slidably mounted on the female seat 1 and fixed to the pressure block 52. The pressure block 52 is placed in the locking cavity 12 and abuts against the locking block 41.

[0040] Specifically, when installing the male connector 2, first press the slide key 51 to drive the pressure block 52 to swing the locking block 41 outward, so as to compress the spring 411 to deform and store energy and make the latch 412 move away from the through hole 30. Then, smoothly insert the connecting post 20 into the through hole 30 and make the boss 220 move down to the side of the latch 412. At this time, release the slide key 51 so that the spring 411 releases energy and restores its original state, driving the locking block 41 to swing inward, thereby making the latch 412 return to its original position and abut against the boss 220, and making the pressure block 412 move away from the through hole 30. Block 52 and slide key 51 are reset; similarly, when disassembling the male head 2, first press slide key 51 to drive pressure block 52 to swing locking block 41 outward, so as to compress spring 411 to deform and store energy and make locking tongue 412 disengage from boss 220, and then move male head 2 upward so that connecting post 20 is away from through hole 30; therefore, by setting slide key 51 and pressure block 52 to be used in conjunction with locking block 41 and spring 411, the disassembly and assembly of male head 2 can be made more convenient, effectively improving the ease of operation.

[0041] Furthermore, two locking blocks 41 are provided and symmetrically arranged on both sides of the through hole 30, so that the two locking tongues 412 can simultaneously abut against the two points of the boss 220. The pressure block 52 is located in the middle of the two locking blocks 41 and can simultaneously abut against and drive the two locking blocks 41. The design of the two locking blocks 41 allows the two locking tongues 412 to simultaneously abut against the boss 220 to form an axial limit, thereby effectively improving the installation stability of the male head 2. The design of the pressure block 52 being located in the middle of the two locking blocks 41 and simultaneously abutting against the two locking blocks 41 allows the user to drive the two locking blocks 41 to swing synchronously by pressing the same sliding key 51, thereby improving the convenience of operation.

[0042] It should be noted that in other embodiments, the unlocking component 5 may also use other manual components or electric components such as micro cylinders and micro motors to control the swing of the locking block 41. Since there are many types of related components, this invention does not limit them.

[0043] See appendix Figure 4 - Appendix Figure 8 To ensure that the circumferential fixing member 3 has rotational damping during rotation, the circumferential fixing member 3 and the rotating cavity 11 can be configured as an interference fit, or a damping member 6 adapted to the circumferential fixing member 3 can be installed on the side of the rotating cavity 11 of the female seat 1. The former can save manufacturing costs, but is prone to wear after long-term use, while the latter will slightly increase manufacturing costs, but has a longer service life. Manufacturers can choose according to actual needs. In order to extend the service life, this embodiment prioritizes the use of damping member 6 to provide rotational damping for the circumferential fixing member 3.

[0044] See appendix Figure 3 - Appendix Figure 10 The circumferential fixing member 3 adopts a gear 31, which is rotatably installed in the rotating cavity 11 and has multiple tooth grooves 310 arranged in a circular array. The through hole 30 is formed at the axis of the gear 31. The damping member 6 includes a tooth block 61 and a spring 62. The tooth block 61 is slidably installed on the female seat 1 and has a retaining tooth 610. The retaining tooth 610 is placed in the rotating cavity 11 and meshes with the tooth groove 310. The spring 62 is set on the female seat 1 and abuts against the retaining tooth 610 and the female seat 1.

[0045] Specifically, under normal circumstances, the locking tooth 610 engages with the tooth groove 310, and the spring 62 applies pressure to the tooth block 61 to provide preload, so that the gear 31 has rotational damping. When the male head 2 is rotated so that the gear 31 overcomes the rotational damping, the locking tooth 610 will disengage from the current slot and drive the tooth block 61 to move, compressing the spring 62 to deform and store energy. When the gear 31 continues to rotate so that the next slot aligns with the locking tooth 610, the spring 62 releases energy and recovers, so that the tooth block 61 moves so that the locking tooth 610 engages with the corresponding slot and provides preload again so that the gear 31 has rotational damping again.

[0046] Therefore, with the combined action of gear 31, tooth block 61 and elastic element, male head 2 can rotate around the positive or negative direction to adjust the rotation angle at will, and after the pressure on male head 2 stops, male head 2 can also be stably stopped at the current angle position due to sufficient rotational damping; on the other hand, during the rotation of male head 2, the cooperation of the above components can also provide a certain amount of vibration feedback and sound feedback, so that users can know whether male head 2 has rotated to the correct position, enrich the operating feel, and further improve the user experience.

[0047] It should be noted that in other embodiments, the damping element 6 can also be a damper (not shown in the figure). By installing the damper on the inner wall of the rotating cavity 11 and connecting it to the circumferential fixing element 3, rotational damping can also be provided to the circumferential fixing element 3. Therefore, since there are many types of damping elements 6, this invention does not limit them.

[0048] See appendix Figure 4 - Appendix Figure 8 The female seat 1 is also provided with a keyway 13 that connects the rotating cavity 11, the locking cavity 12 and the outside; the sliding key 51 is slidably installed in the keyway 13, and the end of the sliding key 51 protrudes from the keyway 13 to the outside; the pressure block 52 is placed in the locking cavity 12 and abuts against the locking block 41; the tooth block 61 is slidably installed in the keyway 13; the locking tooth 610 is placed in the rotating cavity 11 and meshes with the tooth groove 310; the spring 62 is placed in the keyway 13 and abuts against the tooth block 61 and the sliding key 51.

[0049] Specifically, since the spring 62 abuts against the toothed block 61 and the sliding key 51, the spring 62 can continuously apply pressure to the toothed block 61 and the sliding key 51. Under this structural design, when the gear 31 rotates, the spring 62 squeezed by the toothed block 61 can drive the sliding key 51 to stay stably in the initial position, so as to prevent the sliding key 51 from moving inward on its own when the gear 31 rotates, causing the swing block to cause the locking tongue 412 to disengage from the boss 220. Similarly, when the sliding key 51 is pressed to drive the locking block 41 to swing, the spring 62 squeezed by the sliding key 51 can drive the locking teeth 610 on the toothed block 61 to tightly engage with the current tooth groove 310, so as to prevent the gear 31 from automatically rotating and changing its angle when the sliding key 51 moves. Therefore, the above structural design can completely eliminate the interference between the circumferential fixing part 3 and the axial locking part 4, further improve the structural stability, and effectively extend the service life of the relevant components.

[0050] On the other hand, the compact structural design of mounting the slide key 51, tooth block 61 and spring 62 in the same keyway 13 means that the female seat 1 does not need to open more mounting slots to place the slide key 51 and tooth block 61, which effectively reduces the mold opening difficulty of the female seat 1 and reduces the volume of the female seat 1.

[0051] See appendix Figure 3 - Appendix Figure 6 and attached Figure 13 A magnetic block 20x is also installed on the connecting column 20, and a magnetic block 1x is installed at the bottom of the female seat 1. The magnetic block 1x can attract the magnetic block 20x.

[0052] Specifically, when the connecting post 20 passes through the through hole 30 and enters the female seat 1, the magnetic block 20x and the magnetic suction block 1x correspond vertically. Although there is a gap between them or they are separated by a solid wall, if their magnetic forces are strong enough, they can still achieve a reliable adsorption connection. Therefore, the combined use of magnetic blocks 20x and 20x can not only assist the connecting post 20 in inserting into the through hole 30 to complete the quick positioning and installation of the male connector 2, but also provide a certain rotational damping force and axial limiting force to the male connector 2 to enhance the installation stability of the male connector 2, further improving the overall user experience.

[0053] Furthermore, in order to ensure that the magnetic block 1x can accurately correspond to and attract the magnetic block 20x, the magnetic block 1x can be installed on the bottom wall of the lock cavity 12 and coaxial with the through hole 30.

[0054] See appendix Figure 1 - Appendix Figure 14 The present invention also includes a mounting component 7, which is disposed on the female seat 1 and is used to fix the female seat 1 to a specific object for the convenience of normal use by the user.

[0055] Since this latch has a wide range of applications, and the structure of the mounting component 7 varies in different applications, this invention does not impose any limitations on it. However, for ease of understanding, the following examples are provided: Case 1, see appendix Figure 1 - Appendix Figure 10 The mounting component 7 adopts a clamping seat 71. One end of the female seat 1 is hinged to the clamping seat 71, and the other end of the female seat 1 is provided with a buckle 14. The clamping seat 71 is provided with a fixing buckle 710 that can be engaged or disengaged from the buckle 14.

[0056] Specifically, when the fixing buckle 710 of the clamping seat 71 engages with the buckle 14 of the female seat 1, a clamping space is formed between the clamping seat and the female seat 1. With the help of this clamping space, the female seat 1 can be installed on objects such as bags and electronic products. When the clamping seat 71 is pried open to disengage the fixing buckle 710 from the buckle 14, the female seat 1 can be removed.

[0057] Case 2, see appendix Figure 11 - Appendix Figure 14 The mounting component 7 adopts a magnetic base 72, which is fixedly mounted on the female base 1. The bottom of the magnetic base 72 is provided with a magnetic ring 720, which is integrally formed or composed of multiple magnets arranged in a circular array.

[0058] Specifically, the design of the magnetic ring 720 allows the magnetic base 72 and the female base 1 to be fixed to devices such as refrigerators and mobile phones that can be attracted to the magnetic ring 720 (not shown in the figure). When the magnetic base 72 is fixed to a refrigerator, the female base 1, together with the male head 2 with the decoration attached, can be used as a refrigerator magnet. When the magnetic base 72 is fixed to a mobile phone, the female base 1, together with the male head 2 with the decoration attached, can be used as a mobile phone pendant. In addition, the male head 2 can also be designed as a structure with a supporting function, so that the whole can also be used as a mobile phone stand.

[0059] It should be noted that, apart from the different structures of mounting component 7 and the adaptive adjustments to the shape of female connector 1, the other components and structural principles remain consistent in the two cases. Therefore, the usage of male connector 2 and female connector 1 in Case 2 will not be repeated here.

[0060] It should also be noted that, although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
