[0045] The wireless positioning device such as AirTag is widely used in the tracking of personal articles, pets and children due to its small size and portability. Users usually fix it on the target object through a key ring or a rope. However, due to the small size of the device, a protective shell needs to be additionally equipped to ensure firm installation. The existing protective shell performs poorly in dealing with complex environments, such as collisions and falls during outdoor activities, resulting in the risk of the device falling off and affecting the user experience. Therefore, improving the firmness and impact resistance of the protective shell is crucial to enhance the stability of the device.

[0046] To this end, the wireless positioning device protection device provided in the embodiments of the present application solves the problem of poor firmness of the existing protective shell of the wireless positioning device in complex environments and the risk of the wireless positioning device falling off, increases the firmness of the entire device by mutually screwing and locking the first base portion and the second base portion and aligning and engaging the first joint body and the second joint body, is more stable and firm, improves the structural strength, and avoids the risk of the wireless positioning device falling off in complex environments.

[0047] For better understanding of the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0048] Referring to Figures 1-11 The utility model embodiment shows a wireless positioning equipment 4 protection device, include: first attachment element 1, second attachment element 2 and internal space 3, first attachment element 1, including first base body part 11 and first attachment part 12, first attachment part 12 is located in the edge of first base body part 11, be equipped with first joint body 13 on first attachment part 12, second attachment element 2, including second base body part 21 and second attachment part 22, second attachment part 22 is located in the edge of second base body part 21, be equipped with second joint body 23 on second attachment part 22, the second base body part 21 with first base body part 11 both center axis 5 coincide, internal space 3 is formed by the boundary between first base body part 11 and second base body part 21, for accommodating wireless positioning equipment 4, wherein, first base body part 11 with second base body part 21 mutual screw lock solid, first attachment part 12 with second attachment part 22 coincide so that first joint body 13 with second joint body 23 alignment joint.

[0049] Specifically, referring to Figures 1-4The wireless positioning device 4 of the embodiment can be an Airtag, and the first attachment element 1 and the second attachment element 2 constitute a protective shell of the Airtag, which can be attached to the target object so that the wireless positioning device 4 can obtain the positioning of the target object. The overall structure of the first attachment element 1 and the second attachment element 2 is basically the same, and the first attachment element 1 is described below. The first attachment element 1 is a substantially circular shell, wherein the first base part 11 is circular, and the first attachment part 12 is arranged outside the edge of the circular first base part 11 and protrudes outward relative to the circular first base part 11 by a part, so that the first attachment element 1 is not a completely circular shell, but a substantially circular shell. The first base part 11 and the second base part 21 are designed to be circular in order to adapt to the shape of the circular Airtag, and the first base part 11 and the second base part 21 share a common axis 5 and are arranged above and below each other, defining an internal space 3 for placing the Airtag. When the first attachment element 1 and the second attachment element 2 are assembled, the Airtag is first placed on the first base part 11 or the second base part 21, the first base part 11 and the second base part 21 are centered and stacked, and then they are twisted relative to each other, for example, the first base part 11 can be rotated towards the second base part 21, or the second base part 21 can be rotated towards the first base part 11, or both can be rotated towards each other, thereby completing the locking, and the first base part 11 and the second base part 21 together wrap the Airtag in the internal space 3 and protect it. The first attachment part 12 and the second attachment part 22 are structures for attaching the first attachment element 1 and the second attachment element 2 to the target object, and their structural strength needs to be further improved in complex environments. Therefore, the first engagement body 13 is arranged on the first attachment part 12, and the second engagement body 23 is arranged on the second attachment part 22, and the first engagement body 13 and the second engagement body 23 are engaged to tighten the first attachment part 12 and the second attachment part 22, so that the first attachment part 12 and the second attachment part 22 are stably and firmly engaged, further increasing the firmness of the entire device. The engagement mode of the first attachment part 12 and the second attachment part 22 is simple and convenient, specifically, when the first base part 11 and the second base part 21 are centered and stacked, the first attachment part 12 and the second attachment part 22 are offset relative to each other and form a certain angle therebetween, and then the first base part 11 and the second base part 21 are twisted relative to each other to the right position, the first attachment part 12 and the second attachment part 22 are coincided, the first engagement body 13 and the second engagement body 23 are properly positioned and engaged, the first attachment part 12 and the second attachment part 22 are tightened, there is no extra operation, and only twisting is needed, which is convenient and fast.

[0050] By this embodiment, the first attachment part 12 and the second attachment part 22 are fastened by the alignment and engagement of the first joint body 13 and the second joint body 23, so that the first attachment part 12 and the second attachment part 22 are firmly engaged, new fixing points are added for the first attachment element 1 and the second attachment element 2, the firmness of the entire device is further increased, it is more stable and firm, the structural strength is improved, and even in the face of complex environment, the risk of falling of the wireless positioning device 4 can be avoided, and the reliability of the wireless positioning device 4 is improved.

[0051] With reference to Figure 5 In an embodiment, a window 111 for exposing the wireless positioning device 4 is formed on the first base part 11, and the first attachment element 1 further comprises a cover 14 covering the window 111. Specifically, the existing protective shell is usually designed with a window 111 to expose a part of the wireless positioning device 4, but this may cause the device to be scratched or damaged, affecting its appearance and function. Therefore, the window 111 for exposing the wireless positioning device 4 is formed on the first base part 11, and the first attachment element 1 further comprises a circular transparent cover 14 designed to cover the window 111, ensuring that the wireless positioning device 4 is not directly exposed. By setting a special transparent cover 14 to cover the window 111, not only the signal transmission of the wireless positioning device 4 is ensured, but also an additional physical protection layer is provided to prevent the AirTag surface from being scratched or damaged, solving the problem of vulnerability in the existing protective shell design and enhancing the overall durability and user experience of the device.

[0052] In this embodiment, the edge of the cover 14 is ultrasonically welded to the first base part 11. Specifically, the cover 14 and the first base part 11 can be connected by adhesion or ultrasonic welding, and the embodiment adopts ultrasonic welding. The edge of the cover 14 and the first base part 11 are fixed by ultrasonic welding. This assembly method not only improves the sealing performance between the cover 14 and the first base part 11, but also significantly enhances the firmness and impact resistance of the overall structure. Ultrasonic welding is an efficient and stable connection method that can provide stronger bonding than traditional adhesion, ensuring that the cover 14 will not easily separate from the first base part 11 even under extreme conditions, thereby effectively preventing accidental falling of the wireless positioning device 4 due to shell damage.

[0053] With reference to Figure 5In a specific embodiment, the cover 14 and the first base part 11 are coaxial with the central axis 5, and a plurality of pairs of ultrasonic lines 141 are arranged on the edge of the cover 14 around the central axis 5, each pair of ultrasonic lines 141 being radially symmetric about the central axis 5. Specifically, in the manufacturing process of the wireless positioning device 4 protection device, if there is no special design, uneven energy distribution and glue overflow phenomenon are easy to occur when the cover 14 is connected with the first base part 11 by ultrasonic welding technology, which affects the welding quality and product appearance. Therefore, the cover 14 and the first base part 11 of the present embodiment are coaxial with the central axis 5, and a plurality of pairs of ultrasonic lines 141 are arranged on the edge of the cover 14 around the central axis 5, each pair of ultrasonic lines 141 being radially symmetric about the central axis 5. This design uses ultrasonic lines 141 as energy directors or welding ribs to concentrate ultrasonic energy in a specific area, thereby achieving more precise energy application. Specifically, the ultrasonic lines 141 are designed as a raised thin line at the welding interface. These ultrasonic lines 141 not only help to focus energy, concentrating vibration energy in a small area, but also help to precisely control the melting area, reducing the risk of glue overflow. In addition, since each pair of ultrasonic lines 141 is radially symmetric, it ensures uniform energy distribution during welding, further enhancing the welding effect. By using a plurality of pairs of radially symmetric ultrasonic lines 141 design for ultrasonic welding, the ultrasonic lines 141 can concentrate ultrasonic energy in a small area, effectively reducing the overall energy input required, improving welding efficiency, and since the energy is concentrated on the ultrasonic lines 141, the melting process mainly occurs on this line, which helps to precisely control the welding area, limiting the melting range and significantly reducing the risk of glue overflow, thereby shortening the welding time and reducing the welding cost, and reducing the overflow and improving the product appearance effect.

[0054] Referring to Figure 4 In an embodiment, a first attachment through hole 121 is formed on the first attachment part 12, and a second attachment through hole 221 is formed on the second attachment part 22, and the first attachment through hole 121 is aligned and coincided with the second attachment through hole 221. Specifically, a first attachment through hole 121 and a second attachment through hole 221 are respectively formed on the first attachment part 12 and the second attachment part 22, and the two through holes are aligned and coincided to form a through hole for hanging when assembled, and the two are accurately aligned when assembled to form a unified hanging point. The through hole allows the user to securely hang the wireless positioning device 4 on a backpack, pet collar or other target object by means of a rope or key ring.

[0055] Referring to Figure 6In the embodiment, the first engaging body 13 is arranged on the side of the first attachment through hole 121 away from the central axis 5, and the second engaging body 23 is arranged on the side of the second attachment through hole 221 away from the central axis 5. Specifically, in actual application, if the first attachment part 12 and the second attachment part 22 are not sufficiently reinforced at the position close to the edge, a gap or an “opening” state may occur, affecting the firmness and durability of the entire device. The embodiment further optimizes the position design of the engaging body, that is, the first engaging body 13 is arranged on the side of the first attachment through hole 121 away from the central axis 5, and the second engaging body 23 is arranged on the side of the second attachment through hole 221 away from the central axis 5. This arrangement makes the engaging body closer to the edge, preventing the gap or “opening” phenomenon that may occur at the edge. Through the embodiment, the engaging body is placed in a more outer position, so that even when subjected to external pressure or impact, the tight connection between the first attachment part 12 and the second attachment part 22 can be ensured, the stability of the overall structure is improved, the structural strength of the edge part is strengthened, the risk of wear or damage due to long-term use is reduced, and the service life is prolonged.

[0056] Referring to Figure 7 In an embodiment, the first engaging body 13 is a positioning boss, and the second engaging body 23 is a positioning groove. Specifically, in order to ensure that the first attachment element 1 and the second attachment element 2 can be firmly combined after assembly and avoid separation due to external impact or vibration, a reliable connection mechanism is needed. The embodiment proposes a firm combination structure, that is, a positioning boss is used as the first engaging body 13, and a positioning groove is used as the second engaging body 23, which are positioned and clamped to achieve stable connection. The positioning boss is a strip-shaped boss, and the positioning groove is a strip-shaped groove. The positioning boss is arranged on the first attachment part 12, and the positioning groove is arranged on the second attachment part 22. When the two parts are screwed and locked, the positioning boss is accurately embedded in the positioning groove, forming a tight fit. Through this precise matching clamping design, not only is the stable connection between the first attachment part 12 and the second attachment part 22 achieved, but also the impact resistance of the overall structure is enhanced. The positioning boss and the positioning groove are positioned and clamped, effectively preventing accidental separation due to external factors, improving the safety and reliability of the equipment.

[0057] Referring to Figure 8In this embodiment, the positioning boss is provided with at least one slope at both ends in the screwing direction, and the range of the slope is 20°-90°. In the assembly process, if there is a lack of proper guiding design between the positioning boss and the positioning groove, it may cause assembly difficulties or damage the components. This embodiment further optimizes the design of the positioning boss, and at least one slope is provided at both ends in the screwing direction. These slopes help guide the positioning boss to smoothly enter the positioning groove, reduce friction resistance, and improve assembly efficiency. The presence of the slope makes the assembly process smoother, reduces the risk of wear caused by forced insertion, and improves the convenience of operation and user experience. In addition, the slopes on both ends of the positioning boss can be designed in multiple sections, for example, the positioning boss is provided with two slopes at one end, which can gradually guide the positioning boss into the positioning groove through different slopes. The first section of the gentle slope reduces the resistance when initially contacting, and the second section of the steep slope accelerates the final engagement process, ensuring a smooth and efficient assembly experience, while reducing the risk of component wear, improving durability, and improving operational convenience.

[0058] Referring to Figure 8 In this embodiment, the positioning boss is provided with a first slope 131 at one end in the screwing direction, and a second slope 132 at the other end in the unscrewing direction, and the first slope 131 is smaller than the second slope 132. Specifically, in actual use, it is necessary to ensure that the positioning boss is easy to assemble and not easy to accidentally detach. This embodiment proposes a differentiated slope design, i.e., the positioning boss is provided with a smaller first slope 131 at one end in the screwing direction, and a larger second slope 132 at the other end in the unscrewing direction. When the positioning boss is screwed in, the smaller first slope 131 makes it easier for the positioning boss to be engaged into the positioning groove, making the assembly smoother. When the positioning boss is unscrewed, the larger second slope 132 makes it more difficult for the positioning boss to slide out of the positioning groove, increasing the difficulty of disassembly, thereby improving the stability of the connection. By setting different slope angles, it is ensured that the positioning boss can be easily and smoothly engaged into the positioning groove, but when trying to be pulled out in the opposite direction, it will face greater resistance, effectively preventing accidental detachment, greatly enhancing the overall reliability of the device.

[0059] In this embodiment, the first slope 131 ranges from 20° to 60°, the second slope 132 ranges from 60° to 90°, and the height of the positioning boss ranges from 0.4 to 0.6 mm. Specifically, first, in the assembly process, the positioning boss needs to smoothly enter the positioning groove to achieve quick and damage-free installation. If the first slope 131 is too large, it will cause too much resistance when inserted, increasing the difficulty of assembly; if it is too small, it may affect the positioning accuracy and stability. By setting the first slope 131 to 20°-60°, for example, 20°, 30°, 40°, 45°, 50°, 60° or other values within the range, the friction during initial contact can be reduced while ensuring that the positioning boss smoothly enters the positioning groove, making the assembly process smoother. A smaller first slope 131 helps guide the positioning boss to smoothly begin entering the positioning groove, avoiding damage to components caused by hard collisions, while also ensuring adequate guidance for accurate alignment. Illustratively, assuming the first slope 131 is set to 45°, when the user screws, the positioning boss can more easily begin to enter the positioning groove, reducing resistance during initial contact, while providing sufficient guiding force to ensure a smooth subsequent assembly process, making the user's screwing more smooth. Second, to prevent the positioning boss from easily coming out of the positioning groove, an appropriate slope is designed to increase the difficulty of reverse extraction, thereby improving the safety and stability of the connection. Setting the second slope 132 to 60°-90°, for example, 70°, 80°, 90° or other values within the range, can significantly increase the difficulty of the positioning boss being pulled out of the positioning groove, providing a stronger locking effect. A larger slope angle increases the friction and resistance when pulling out in the opposite direction, effectively preventing accidental disengagement and enhancing the overall structural firmness and reliability. Illustratively, if the second slope 132 is set to 80°, the positioning boss is not easily pulled out of the positioning groove even under external force, greatly improving the stability and safety of the device in complex environments, making it suitable for outdoor activities and other application scenarios. Third, the height of the positioning boss directly affects the tightness of its fit with the positioning groove. If the height is insufficient, it may cause loose fit, while if it is too high, it may cause assembly difficulties or damage to components. By controlling the height of the positioning boss to be between 0.4-0.6 mm, sufficient embedding depth can be ensured to maintain a stable connection, while avoiding assembly obstacles or unnecessary wear caused by excessive height. This design balances assembly convenience and connection strength, improving the durability and user experience of the device.

[0060] Referring to Figure 6In the present embodiment, the center of the first attachment through hole 121 and the center of the first base part 11 define a first symmetry axis 6, and the positioning boss is symmetrical about the first symmetry axis 6; the center of the second attachment through hole 221 and the center of the second base part 21 define a second symmetry axis 7, and the positioning groove is symmetrical about the second symmetry axis 7. Specifically, in order to ensure that the positioning boss and the positioning groove can be accurately aligned during assembly, and to avoid difficult assembly or unstable connection due to slight deviations, a reliable alignment mechanism is needed. The present embodiment adopts a symmetry axis-based approach, that is, the center of the first attachment through hole 121 and the center of the first base part 11 define a first symmetry axis 6, and the center of the second attachment through hole 221 and the center of the second base part 21 define a second symmetry axis 7. The positioning boss is symmetrically arranged about the first symmetry axis 6, and the positioning groove is symmetrically arranged about the second symmetry axis 7. When the two attachment elements are screwed and locked, the positioning boss can be accurately and correctly inserted into the positioning groove, achieving precise alignment. Specifically, the existence of the first symmetry axis 6 and the second symmetry axis 7 provides a clear reference datum for the positioning boss and the positioning groove, so that they always maintain a consistent positional relationship during assembly. Whether in the initial contact stage or in the final locking stage, this symmetrical design can effectively reduce assembly errors, improve connection accuracy, achieve seamless docking, and improve the reliability and durability of the entire device.

[0061] With reference to Figure 6 and Figure 7In an embodiment, the second base part 21 is provided with a plurality of rotating female buckles 211 inside the edge thereof, which are distributed equidistantly around the central axis 5; the first base part 11 is provided with a plurality of rotating male buckles 112 inside the edge thereof, which are also distributed equidistantly around the central axis 5; wherein the rotating male buckles 112 and the rotating female buckles 211 are rotatably buckled. Specifically, in order to ensure that the first base part 11 and the second base part 21 can be connected stably and easily operated when assembled, a reliable mechanical locking structure is needed, and the traditional connection mode may have problems of difficult assembly, instability or easy loosening. In the embodiment, the second base part 21 is provided with a plurality of rotating female buckles 211 inside the edge thereof, which are distributed equidistantly around the central axis 5; and the first base part 11 is provided with a plurality of rotating male buckles 112 inside the edge thereof, which are also distributed equidistantly around the central axis 5. The first base part 11 can be provided with a ring body, and the plurality of rotating male buckles 112 are arranged on the side wall of the ring body, facilitating the alignment and assembly of the rotating male buckles 112. When assembled, the rotating male buckles 112 and the rotating female buckles 211 are connected closely by rotating buckling, forming a solid overall structure. The design of the rotating male buckles 112 and the rotating female buckles 211 makes the assembly process simple and intuitive. Only need to stack the two base parts and start to screw, and the rotating male buckles 112 will enter the corresponding rotating female buckles 211 in sequence to complete the buckling. The rotating male buckles 112 and the rotating female buckles 211 are designed to be buckled upside down, both of which are strip-shaped. After the knob is in place, the rotating male buckles 112 and the rotating female buckles 211 are buckled upside down, i.e., buckled from top to bottom, so as to close the internal space 3 of the first base part 11 and the second base part 21. The first base part 11 and the second base part 21 cannot be opened upward, thereby locking the first base part 11 and the second base part 21. Moreover, the design of the plurality of rotating male buckles 112 and the plurality of rotating female buckles 211 distributed equidistantly around the central axis 5 can form a plurality of buckling points, and the structure is more stable and reliable, and has high structural strength. Through the precise matching design of the rotating female buckles 211 and the rotating male buckles 112 in the embodiment, the efficiency and stability in the assembly process are realized, which not only facilitates the assembly, but also greatly enhances the impact resistance and durability of the entire device, ensuring the reliable protection of the wireless positioning device 4 in various environments.

[0062] Reference Figure 10 and Figure 11In this embodiment, the rotating female buckle 211 is provided with an inclined surface 2111 at one end in the screwing-in direction, and a rotation-stopping column 2112 at the other end. Specifically, the screwing-in direction can be the clockwise direction, and the screwing-out direction can be the counterclockwise direction. Of course, it can be understood that the screwing-in direction can be the counterclockwise direction, and the screwing-out direction can be the clockwise direction. At both ends of the rotating female buckle 211, one end is provided with the inclined surface 2111, and the other end is provided with the rotation-stopping column 2112. The design of the inclined surface 2111 helps guide the rotating male buckle 112 to smoothly enter the rotating female buckle 211, reducing the friction at the initial contact, making the assembly process more smooth. The inclined surface 2111 usually has a small angle, which makes it easier for the rotating male buckle 112 to be inserted when it starts to enter the rotating female buckle 211, reducing the resistance at the initial contact. As the rotating male buckle 112 gradually penetrates into the rotating female buckle 211, the inclined surface 2111 provides good guidance, ensuring that the rotating male buckle 112 accurately enters the predetermined position. Once the rotating male buckle 112 reaches the correct position, the rotation-stopping column 2112 will play a role. The rotation-stopping column 2112 is used to prevent the rotating male buckle 112 from rotating too much. When the rotating male buckle 112 reaches the correct position, the rotation-stopping column 2112 will stop the rotating male buckle 112, preventing it from continuing to rotate. The rotating action is stopped, avoiding the situation where the positioning boss slips out of the positioning groove due to excessive rotation, thereby ensuring the precise alignment between the positioning boss and the positioning groove. By setting the inclined surface 2111 and the rotation-stopping column 2112, efficiency and stability in the assembly process are achieved. The inclined surface 2111 reduces the frictional resistance at the beginning of assembly, making it easier for the user to complete the initial docking, improving the convenience of operation. The rotation-stopping column 2112 ensures that the rotating male buckle 112 will not deviate from the best alignment point due to excessive rotation, effectively maintaining the close fit between the positioning boss and the positioning groove.

[0063] With reference to Figure 9 and Figure 10In the embodiment, a buckle slot 212 is formed between every two adjacent rotating female buckles 211, which is the initial placement position of the rotating male buckle 112. Specifically, in order to ensure that the rotating male buckle 112 can be accurately placed, an effective guiding method is needed to help the user to place it initially. A buckle slot 212 is formed between every two adjacent rotating female buckles 211, which provides an initial placement position for the rotating male buckle 112. The buckle slot 212 provides a clear reference point to help the user quickly find the correct assembly position, giving the user quick assembly guidance and reducing errors in the assembly process. Before screwing, the first base part 11 and the second base part 21 are stacked, and each rotating male buckle 112 is placed on the corresponding buckle slot 212, which is the initial placement position of the rotating male buckle 112. As the first base part 11 and the second base part 21 are screwed to each other, the rotating male buckle 112 leaves the buckle slot 212 and enters the rotating female buckle 211 to be buckled. By introducing the buckle slot 212 as the initial placement position of the rotating male buckle 112, not only the operation efficiency is improved, but also the assembly accuracy is enhanced, ensuring the stability and reliability of the final connection.

[0064] With reference to Figure 9 In the embodiment, one of the buckle slots 212 is adjacent to the second attachment part 22, and a foolproof column 213 is arranged on the buckle slot 212 adjacent to the second attachment part 22 to prevent the rotating male buckle 112 from being placed. Specifically, in actual use, if the user mistakenly places the rotating male buckle 112 in the wrong position, it may cause assembly failure or damage to the components. Therefore, the embodiment adds a foolproof column 213, one of the buckle slots 212 is adjacent to the second attachment part 22, and a foolproof column 213 is arranged on the buckle slot 212 to prevent the rotating male buckle 112 from being placed. When the user places it incorrectly, the foolproof column 213 can block the rotating male buckle 112 from being placed, guiding the user to adjust the rotating male buckle 112 to the correct position. The presence of the foolproof column 213 can effectively prevent the user from mistakenly placing the rotating male buckle 112 in this position, avoiding assembly errors. By setting the foolproof column 213, the occurrence of incorrect assembly is effectively prevented, improving the success rate and reliability of assembly, ensuring that the user will not cause assembly failure or component damage due to negligence when assembling.

[0065] In an embodiment, the first base part 11 and the second base part 21 are radially symmetrical about the center axis 5. Specifically, the first base part 11 and the second base part 21 adopt a circular shape or other geometric shapes with radial symmetry.

[0066] In an embodiment, the first attachment portion 12 and the second attachment portion 22 are respectively formed by the edges of the first base portion 11 and the second base portion 21 protruding radially in a direction away from the central axis 5. Specifically, since the first base portion 11 and the second base portion 21 are mainly used to form the internal space 3 to accommodate the Air Tag, there is a lack of sufficient surface area to provide attachment structures. The first attachment portion 12 and the second attachment portion 22 of the present embodiment protrude radially, providing sufficient mounting positions for attachment structures (such as the attachment through holes used for hanging as described above) without affecting the use of the internal space 3. Specifically, the first attachment portion 12 and the second attachment portion 22 extend outward from the edges of the base portions, forming an additional platform or area dedicated to providing attachment structures and engaging bodies, thereby ensuring that these attachment structures and engaging bodies do not interfere with the internally placed Air Tag. By forming the first attachment portion 12 and the second attachment portion 22 to protrude radially, the contradiction between the internal space 3 and the external attachment requirement is effectively resolved, not only providing the necessary space for attachment structures to ensure that the device can be firmly fixed on the target object, but also simplifying the overall structural layout, improving the convenience and stability of assembly. The attachment structures are cleverly arranged on the protruding part of the edge of the base portion, neither affecting the safe placement of the internal Air Tag nor enhancing the reliability of external connection.

[0067] Referring to Figure 6 and Figure 9 In the present embodiment, an included angle a is formed at the transition between the first base portion 11 and the first attachment portion 12, and the range of the included angle a is 120°-130°. Specifically, during the assembly of the wireless positioning device 4 protection device, the user needs a convenient force application position to push the first attachment portion 12 for screwing operation. If the transition is too flat, there is a lack of effective force point, resulting in inconvenient operation. The present embodiment forms an included angle a at the transition between the first base portion 11 and the first attachment portion 12, and the range of the included angle a is 120°-130°. This design makes the outwardly protruding first attachment portion 12 have a certain curvature at the transition, thereby forming a blocking surface in the rotation direction, facilitating the user to apply pushing force with fingers. Specifically, the included angle a not only provides sufficient space for the user's fingers to place, but also ensures the comfort and stability during operation. It should be noted that the structure of the second attachment portion 22 is the same as that of the first attachment portion 12, and the included angle a at the transition between the second attachment portion 22 and the second base portion 21 is also in the range of 120°-130°. By setting the included angle a in a specific range, the user's operation experience is significantly improved, not only providing a clear and comfortable force point for the user, but also enhancing the stability and controllability during screwing. For example, in actual use, the user can easily place his fingers in the included angle a area, use the support and guidance provided by the area to smoothly and effectively complete the screwing operation, improving the assembly efficiency and user experience.

[0068] In the embodiment, the edge surfaces of the first and second attachment portions 12 and 22 are arc surfaces. Specifically, when a user exerts a pushing force on the first or second attachment portion 12 or 22, if the edge surface is relatively sharp, a large stress may be concentrated on the finger, causing discomfort. To this end, the edge surfaces of the first and second attachment portions 12 and 22 are designed as arc surfaces in the embodiment, the arc surfaces have a larger contact area, and the arc surfaces can effectively disperse the pressure exerted on the finger, reduce the stress concentration phenomenon, and provide a more comfortable touch. Specifically, the arc surface design makes the finger contact surface smoother, reduces the local pressure, reduces the pressure points when the finger is stressed, avoids discomfort or marks on the finger due to excessive compression, and improves the convenience and comfort of operation.

[0069] In the embodiment, the width of the first attachment portion 12 occupies a proportion of 7%-20% of the circumference of the first base portion 11. Specifically, the first attachment portion 12 needs to have sufficient width to set the attachment structure and the engagement body, but excessive width will increase the amount of material and weight, affecting portability and cost-effectiveness, and insufficient width cannot meet the functional requirements. Therefore, after verification, the width of the first attachment portion 12 occupies a proportion of 7%-20% of the circumference of the first base portion 11, which not only ensures sufficient space for setting the attachment structure and the engagement body, but also avoids unnecessary waste of material and increase in weight. It should be noted that the structure of the second attachment portion 22 is the same as that of the first attachment portion 12, and the width of the second attachment portion 22 occupies a proportion of 7%-20% of the circumference of the second base portion 21. By precisely controlling the width proportion of the first attachment portion 12, the best balance between function and material use is achieved, not only ensuring that the first attachment portion 12 has sufficient space to install the necessary attachment structure and engagement body, but also effectively controlling the amount of material and weight, improving the portability and cost-effectiveness of the product.

Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
