DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative effort, and other embodiments can also be obtained.

In this document, "one" not only means "only one", but also means "more than one" situation.

[0044] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0045] In this document, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0047] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] In the current wearable device field, for example, the wearing of devices such as smart watches, smart bracelets and the like, the length adjustment structure of the wearing part usually adopts a scheme of lock buckle and multiple hole positions. Specifically, the wearing part is divided into two bands, one band is provided with a lock buckle, and the other band is provided with a plurality of equidistantly arranged holes, and the length adjustment is realized by locking the lock buckle in different hole positions.

[0049] However, the current technology has some obvious problems. Each adjustment must completely separate the lock buckle from the current hole position, resulting in a non-fixed state of the wearing part, which is easy to cause the wearable device to accidentally slip off; moreover, in some motion or one-handed operation scenarios, it is difficult for the user to accurately align the lock buckle with the target hole position, and the adjustment efficiency is low.

[0050] In one embodiment, referring to the drawings Figure 1 The length adjustment structure provided by the present application can adjust the length of the wearing part without unfastening the wearing part, significantly improving the use experience of the wearable device.

[0051] It should be noted that the "effective wearing length" in the present application refers to the length dimension formed by the wearing part around the corresponding part of the human body for one or more circles when the device is worn at a predetermined position (such as wrist, ankle, head, etc.). For different individuals, the effective wearing length they need is different, for example, some people like to wear the wearing part loosely when wearing the wearable device, and the purpose of the length adjustment structure is to meet the diverse wearing needs of different users, and to ensure that various wearable devices can achieve the best wearing effect in different use scenarios.

[0052] In one embodiment, referring to the drawings Figures 1 to 3The length adjusting structure provided by the application is used for adjusting the effective wearing length of the wearing part of the wearing device, and mainly comprises a first head particle 1, a second head particle 2 and an execution element 3. The first head particle 1 is provided with a first mounting cavity 10, and a first limiting part 11 is arranged in the first mounting cavity 10. The second head particle 2 is movably connected with the first head particle 1 and is at least partially located in the first mounting cavity 10. The second head particle 2 and the first head particle 1 are matched with each other and can produce relative movement in an adjusting state, so as to realize the adjustment of the effective wearing length of the wearing part.

[0053] As shown in Figure 2 、 Figure 5 and Figure 6 , the execution element 3 can be movably arranged in the second head particle 2 and specifically comprises a pressing part 31 and a second limiting part 32, and the pressing part 31 is connected with the second limiting part 32. The function of the pressing part 31 is to make the second limiting part 32 move through the operation of the pressing part 31 when the wearer needs to adjust the length of the wearing part, so that the second limiting part 32 is separated from the first limiting part 11, and then the first head particle 1 and the second head particle 2 can move relatively to realize the length adjustment.

[0054] In the wearing state, the second limiting part 32 is opposite to the first limiting part 11, which ensures that the connection between the first head particle 1 and the second head particle 2 is firm and stable. At this time, the length of the wearing part has been locked and is not easy to loosen or fall off, which ensures the safety of the wearing device in the use process.

[0055] When the length of the wearing part needs to be adjusted, the wearer operates the pressing part 31, the pressing part 31 drives the second limiting part 32 to move, and then the separation of the second limiting part 32 and the first limiting part 11 is realized. In this way, the locking between the first head particle 1 and the second head particle 2 can be released, and at this time the user can control them to produce relative movement, and then adjust the length of the wearing part. Through simple operation, the wearer can accurately adjust the length range of the wearing part to adapt to different wearing needs.

[0056] Among them, the first limiting part 11 and the second limiting part 32 can be designed as different limiting structures, for example, using concave-convex matching design to enhance the locking effect and ensure that the wearing part is more stable in the wearing state. The pressing part 31 can adopt different shapes and materials, for example, wrapped with rubber or soft plastic to enhance the comfort and anti-skid performance during wearing.

[0057] It can be understood that the embodiment is different from the conventional scheme which needs to completely unlock the wearing part lock, and only needs to operate the pressing part 31 to easily adjust the length of the wearing part, which is more convenient and fast. The length adjusting structure in the application adopts a simplified movable connection and limiting design, reduces the failure points, prolongs the service life and improves the durability of the product.

[0058] It should be noted that in daily use, the length adjustment range required by the user for most wearable devices, such as watches, is actually relatively limited. However, the conventional design covers a wide range of possible sizes, and a large number of holes are provided, but many of these holes are rarely or even never used in actual use, which undoubtedly causes waste of materials and unnecessary increase of processing procedures, increasing production costs.

[0059] In the present embodiment, by relative movement between the head particles, relative locking or unlocking between the limiting parts, the limitation of the traditional technology of this kind of buckle-hole adjustment mode is broken, and the length of the wearing part can be flexibly adjusted according to the actual needs of the user within a certain range, improving the fit and comfort of the wearable device, and at the same time, reducing the adverse situation of long processing period due to the need for a large number of holes.

[0060] Based on the above, it can be optimized to add a feedback device on the execution element 3, which vibrates or sounds to feedback the operation state to the user when the second limiting part 32 is in contact or separated from the first limiting part 11, or sets a length indication mark between the first head particle 1 and the second head particle 2, so that the user can intuitively understand the current length value of the adjustment.

[0061] In this way, the structure can be applied to different types of wearable devices, such as sports bands, smart watches, backpacks, wrist guards, etc., and different materials can be selected for manufacturing according to different material and strength requirements, such as aluminum alloy, stainless steel, plastic, etc., to meet the strength, durability and comfort requirements of different devices.

[0062] Further, the length adjustment structure further comprises a head particle assembly module, which is arranged between the first head particle 1 and the second head particle 2, and is used to realize the movable connection of the first head particle 1 and the second head particle 2.

[0063] In the present scheme, the head particle assembly module can ensure that the relative position of the first head particle 1 and the second head particle 2 always remains within the designed range, so that the relative movement of the first head particle 1 and the second head particle 2 is uniform and accurate during the length adjustment of the wearing part, avoiding unnecessary deviation or jamming phenomenon, making the adjustment of the wearing part more smooth, and enhancing the use experience.

[0064] In some embodiments, the headpiece assembly module may employ a gear and rack mechanism. A gear can be fixedly installed in the first mounting cavity 10 of the first headpiece 1, while a gear meshing with the rack is mounted on the second headpiece 2. When the effective wearing length needs to be adjusted, the operating actuator 3 drives the second headpiece 2 to move. Due to the meshing relationship between the gear and the rack, the second headpiece 2 will move smoothly along the rack direction. Alternatively, a sliding connection structure may be used, which will be described in detail later. In short, any method that enables the movable connection between the two headpieces can be adopted as long as it does not conflict with the basic concept of this application.

[0065] In one embodiment, based on the above embodiments, the head assembly module includes a first assembly part 41, a second assembly part 42, and a connector 43. See the appendix to the specification. Figure 4 The first assembly part 41 is a groove-shaped structure with a certain length. The length of the groove-shaped structure corresponds to the adjustment threshold of the effective wearing length of the wearer. That is, when adjusting the length of the wearer, the length range of the groove determines the minimum and maximum adjustable length of the wearer. The groove-shaped structure design has good guiding and positioning functions, which can ensure that the sliding connection between the first end piece 1 and the second end piece 2 remains smooth during the adjustment process, avoiding jamming or deviation during the adjustment process.

[0066] like Figures 4 to 6 As shown, a first mounting portion 41 is provided on the two side walls of the first mounting cavity 10, a second mounting portion 42 is provided on the two side walls of the second head piece 2, and a connecting member 43 is provided on the actuating element 3. In the first embodiment, as shown in the attached diagram... Figure 8 As shown, the connector 43 passes through the second assembly part 42 and the end of the connector 43 is movably embedded in the first assembly part 41; in contrast, in the second embodiment, the connector 43 passes through the first assembly part 41 and the end of the connector 43 is embedded in the second assembly part 42.

[0067] In this design, the connector 43 and the actuator 3 within the head assembly module are integrated, further reducing space requirements. The actuator 3, through its tight integration with the connector 43, achieves functional integration, avoiding the separation of multiple components and complex structures that may exist in traditional designs, thereby improving the overall compactness and stability of the structure.

[0068] In actual use, the first head grain 1 and the second head grain 2 are connected by the head grain assembly module to form a sliding connection, and the wearer can make the second head grain 2 slide relative to the first head grain 1 by operating the pressing part 31 in the execution element 3. Specifically, in the wearing state, the end of the connecting piece 43 is fixed at a certain position of the first limiting part 11, which ensures the firm connection between the first head grain 1 and the second head grain 2, thereby maintaining the stability of the wearing piece and preventing it from loosening or falling off. In the adjusting state, the wearer presses the execution element 3 to unlock the first limiting part 11 and the second limiting part 32, so that the connecting piece 43 can slide along the groove-shaped structure of the first assembly part 41, thereby adjusting the relative position between the first head grain 1 and the second head grain 2 to achieve the effect of adjusting the length of the wearing piece.

[0069] It should be noted that two connection schemes for the connecting piece 43 are proposed in this embodiment. When the first scheme is adopted, in a common structural layout, for example, as can be seen from FIG. 1, the outer side wall of the second head grain 2 is located inside the first head grain 1, and then the second head grain 2 mainly moves in the internal space of the first head grain 1. Therefore, the first scheme is beneficial to protect the internal structure and save external space to some extent, so that the entire length adjustment structure is more compact. Figure 8

[0070] When the second scheme is adopted, there is another structural layout (not embodied in the drawings), in which part of the second head grain 2 is inside the first head grain 1, which is used for the butt joint of the limiting part to ensure the stable locking of the first head grain 1 and the second head grain 2 in the wearing state. Meanwhile, another part is outside the first head grain 1, which is used for the sliding connection of the two. At this time, the connecting piece 43 passes through the first assembly part 41 and then forms a connection with the second assembly part 42. Since the first assembly part 41 is a groove-shaped structure, the connecting piece 43 can still drive the second head grain 2 to slide.

[0071] In one embodiment, based on the above, further, a guide groove 70 is arranged in the first mounting cavity 10 of the first head grain 1, the first assembly part 41 in the above embodiment is arranged in the guide groove 70, a guide rail 71 corresponding to the guide groove 70 is arranged on the second head grain 2, and the second assembly part 42 in the above embodiment is arranged on the guide rail 71, so that the second head grain 2 can smoothly slide in the first mounting cavity 10 along the guide groove 70. Meanwhile, the cooperation of the guide groove 70 and the guide rail 71 can also prevent the second head grain 2 from being pulled out of the first head grain 1, thereby ensuring the safety and reliability of the user during operation.

[0072] The above and other embodiments can be further understood with reference to the accompanying drawings, which show, by way of example, specific embodiments thereof. Figure 4 and Figure 5 ​In the above embodiments, the first assembly part 41 and the second assembly part 42 are partially overlapped with the guide groove 70 and guide rail 71 in this embodiment. This allows the guiding and assembly connections to be integrated within a small area, avoiding internal structural complexity and facilitating mass production.

[0073] In one embodiment, such as Figure 8 As shown, the connector 43 has an elastic structure 431. Specifically, the two ends of the connector 43 can retract inward during the assembly process. When the connector 43 is installed in place, its two ends will naturally pop outward, thereby embedding into the corresponding assembly part.

[0074] The configuration in this embodiment reduces assembly difficulty. For example, when assembling wearable devices in batches in a production workshop, workers can quickly insert the connector 43 into the corresponding assembly part, reducing time wasted due to assembly difficulties and significantly improving production efficiency.

[0075] It should be noted that the structure of the connector 43 in this embodiment is similar to the "spring ear" in the prior art. In the traditional "spring ear" structure, the ear is usually retracted during assembly and pops out and fixes the mating parts after assembly, thereby ensuring that the connector 43 is not easy to fall off and can withstand a certain mechanical load.

[0076] Depending on the actual application environment and requirements, the elastic structure 431 of the connector 43 can be made of different elastic materials. For example, for applications requiring high wear resistance and corrosion resistance, a metal spring material can be selected; for lightweight wearable devices, a highly elastic plastic or composite material can be selected.

[0077] Furthermore, such as Figure 1 As shown, a protective layer 432 can be fitted over the outside of the connector 43. The protective layer 432 covers the outside of the elastic structure 431 to provide additional protection, thus forming a multi-layer design of the connector 43, which enables the connector 43 to withstand greater external forces and improve its overall stability and reliability.

[0078] Based on the above embodiments, the connector 43 adopts a cylindrical design to form a rotational connection between the actuator 3 and the second head 2. It can be understood that the cylindrical shape provides a clear axis of rotation for the connector 43, so that when the pressing part 31 is pressed by an external force, the second limiting part 32 and the pressing part 31 can rotate around the connector 43 as the axis.

[0079] In one embodiment, as shown in the appendix Figure 5The second head particle 2 has a second mounting cavity 20 and an opening 21 communicating with the second mounting cavity 20, and the length adjusting structure further comprises a reset member 50, which is installed in the second mounting cavity 20 of the second head particle 2 together with the execution element 3, and the pressing part 31 is exposed at least partially through the opening 21 to provide an operation space.

[0080] When the user presses the pressing part 31, the force is transmitted to the execution element 3 as a whole through the pressing part 31, and the reset member 50 cooperating with the execution element 3 is deformed by the external force. In the process of deformation of the reset member 50, the second limiting part 32 associated with the reset member 50 can move synchronously to realize the separation from the first limiting part 11, and at this time, the first head particle 1 and the second head particle 2 can move relatively to complete the adjustment of the effective wearing length of the wearing device.

[0081] When the user releases the pressing part 31, the reset member 50 is automatically reset by virtue of its elastic property, and in the process of resetting, the second limiting part 32 is returned to the initial state, i.e., the second limiting part 32 is reconnected with the first limiting part 11 to complete the locking after the length adjustment, thereby avoiding the possibility of unintentional adjustment of the wearing device.

[0082] Specifically, reference can be made to the drawings attached to the specification Figures 6 to 8 The reset member 50 can be a torsion spring, the main body part of the torsion spring is sleeved on the outer periphery of the connecting member 43, and the two free ends of the torsion spring are respectively in abutment with the inner wall of the second head particle 2 and the execution element 3.

[0083] Reference can be made to the drawings attached to the specification Figure 7 When the pressing part 31 is pressed, the execution element 3 rotates around the connecting member 43 as the rotation axis (in the foregoing, the connecting member 43 forms the rotation connection between the execution element 3 and the second head particle 2). In this process, the distance between the two free ends is compressed, and the torsion spring is elastically deformed to store elastic potential energy; at the same time, the second limiting part 32 of the execution element 3 moves synchronously to realize the separation between the second limiting part 32 and the first limiting part 11, and at this time, the first head particle 1 and the second head particle 2 can move relatively to adjust the effective wearing length of the wearing device. When the user stops pressing the pressing part 31, the torsion spring restores to the original state by virtue of the stored elastic potential energy, the distance between the two free ends is increased, the execution element 3 is reversely rotated, and the second limiting part 32 is returned to the initial state to be reconnected with the first limiting part 11.

[0084] In one embodiment, based on the above, the width of the opening 21 on the second head particle 2 is greater than the width of the pressing part 31, ensuring that there is a preset gap 220 between the edges of the opening 21 and the pressing part 31. In this way, it can effectively prevent the pressing part 31 from colliding with the edge of the second head particle 2 during movement, thereby avoiding structural damage or jamming due to mechanical friction or impact, prolonging the service life of the entire length adjustment structure, and reducing the probability of product failure due to component wear.

[0085] Further, with reference to the accompanying drawings Figure 2 and Figure 7 The execution element 3 is provided with a shielding section 33, which is closely connected with the edge of the pressing part 31 and extends away from the body of the pressing part 31, forming a shielding surface inside the second mounting cavity 20, which can cover the preset gap 220 between the opening 21 and the pressing part 31.

[0086] It can be understood that in daily use, dust, sweat, liquid and other impurities may enter the second mounting cavity 20 through the preset gap 220, affecting the normal operation of the internal components such as the execution element 3 and the reset member 50, and reducing their service life. The shielding section 33 can reduce the probability of impurities entering the second mounting cavity 20, provide protection for internal components, and improve the reliability and stability of the length adjustment structure.

[0087] On the other hand, without the shielding section 33, the user can see the internal structure of the length adjustment structure from the outside, which will destroy the overall beauty and harmony of the product. By shielding the internal structure with the shielding section 33, only the simple and complete appearance of the pressing part 31 is presented externally, improving the overall beauty of the product and meeting the user's requirements for the appearance of the product.

[0088] In one embodiment, as Figure 7 shown, the second limiting part 32 is provided as a hook structure, and the first limiting part 11 is designed as a card slot structure matched with the hook structure, the hook structure including at least one carding protrusion 320, and the card slot structure including at least one carding recess 110.

[0089] During adjustment of the wearing member, when the pressing part 31 is pressed, the carding protrusion 320 and the carding recess 110 are no longer carded with each other, and the first head particle 1 and the second head particle 2 can move relatively, facilitating adjustment of the length of the wearing member; after adjustment is completed, when the pressing part 31 releases external force, the carding protrusion 320 will automatically embed into the carding recess 110, realizing locking of the first head particle 1 and the second head particle 2, so that the wearing member is kept at a certain fixed length.

[0090] It can be understood that when the clamping protrusion 320 and the clamping recess 110 are matched with each other, a larger external force can be resisted, the relative displacement between the first head grain 1 and the second head grain 2 is effectively prevented, the wearing device can be stably worn in various use scenarios, and the safety of wearing is greatly improved.

[0091] In order to adapt to the design requirements of different wearing devices, the shape, size and matching mode of the clamping hook structure and the clamping groove structure can be adjusted. For example, the shape of the clamping protrusion 320 can be designed as a conical shape, a circular shape, a square shape or other geometric shapes.

[0092] Optionally, near the clamping hook structure and the clamping groove structure, a micro sensor can be installed. When the clamping protrusion 320 is embedded in the clamping recess 110, the sensor can monitor the locking state in real time, and transmit information to a mobile phone APP through wireless communication technology such as Bluetooth, so that the user can intuitively understand the locking state of the wearing device on the mobile phone end. When the clamping protrusion 320 may be separated, an alarm can be sent to prompt the user.

[0093] Further, in the implementation of the present application, the clamping hook structure includes a clamping protrusion 320, and the clamping groove structure includes three clamping recesses 110 (more in actual application), and the clamping recesses 110 are sequentially and spacedly arranged, thereby forming multiple different adjustment positions.

[0094] When the user operates the adjusting element 3 to adjust the length of the wearing device, the pressing portion 31 is pressed, so that the clamping protrusion 320 is separated from the clamping recess 110 in which it is currently located, the locking state between the first head grain 1 and the second head grain 2 is released, and the relative movement between the two is generated.

[0095] In the movement process of the clamping protrusion 320, since the clamping recesses 110 are sequentially and spacedly arranged, the user can flexibly make the clamping protrusion 320 sequentially or intermittently enter different clamping recesses 110 according to actual needs. For example, when the user needs to make a small amplitude length fine adjustment, the clamping protrusion 320 can be sequentially clamped into adjacent clamping recesses 110; when the user needs to greatly adjust the length of the wearing device, the clamping protrusion 320 can be selected to be clamped into clamping recesses 110 which are far away from each other; once the clamping protrusion 320 is clamped into the target clamping recess 110, the first head grain 1 and the second head grain 2 are relocked, and the multi-stage adjustment of the length of the wearing device is completed.

[0096] It can be understood that in the present embodiment, through the arrangement of multiple clamping recesses 110, the wearing device can provide multiple different length adjustment gears. The multi-stage adjustment structure enables the wearing device to be accurately adjusted in a smaller range, meets different use requirements, and the wearer can select a suitable length according to different wearing requirements, thereby improving the wearing comfort and practicability.

[0097] The number and spacing of the clamping recesses 110 can be adjusted according to the requirements of different products. For some wearers that require precise length adjustment, more clamping recesses 110 can be designed, and the spacing between the clamping recesses 110 can be adjusted to provide more adjustment options.

[0098] In one embodiment, the first limiting portion 11 and the second limiting portion 32 are respectively provided with matching guide structures, and the guide structures each include at least one inclined guide portion 61, so that the wearer can move relative to each other under external force without pressing the pressing portion 31, thereby adjusting the effective wearing length of the wearer.

[0099] It should be noted that through the design of the guide portion 61, the first limiting portion 11 or the second limiting portion 32 can be guided to move in a predetermined direction along the guide portion 61 under external force. In other words, each guide portion 61 is designed as an inclined structure, so that the limiting portion can be guided by the guide structure to produce relative movement within a certain range, thereby changing the relative distance between the first head grain 1 and the second head grain 2, which can be compressed or expanded, and further adjusting the effective wearing length of the wearer.

[0100] In this embodiment, the greatest feature of the scheme is that the length adjustment process does not depend on the pressing of the pressing portion 31, so that the user can more conveniently adjust the length of the wearer in the case of inconvenient hands. The material selection of the guide portion 61 should have high wear resistance and anti-friction performance to ensure smooth movement trajectory in long-term use.

[0101] Furthermore, as shown in Figure 7 The guide structure further includes at least one stop portion 62, which is arranged one-to-one with the guide portion 61, and the stop portion 62 is used to limit the reverse movement of the first limiting portion 11 or the second limiting portion 32 after adjustment in the predetermined direction, to ensure that the adjusted length can be stably maintained, and to prevent loosening or misadjustment caused by accidental external force.

[0102] In actual operation, first, the first limiting portion 11 or the second limiting portion 32 moves along the inclined guide portion 61 under external force to achieve length adjustment; when the target length is adjusted, the stop portion 62 acts to prevent the first limiting portion 11 or the second limiting portion 32 from retreating in the opposite direction, ensuring that the wearer is stable and reliable after adjustment.

[0103] Specifically, as can be seen from the drawings, the design of the guide portion 61 and the stop portion 62 can also be integrated into the structure of the clamping protrusion 320 and the clamping recess 110 in this application. One side of the clamping protrusion 320 is provided with a guide portion 61, and the other side is provided with a stop portion 62. The clamping recess 110 is designed correspondingly to the clamping protrusion 320.

[0104] When an external force is applied to the length adjustment structure to adjust the effective wearing length of the wearing piece, if the relative positions of the first head bead 1 and the second head bead 2 need to be changed, the clamping protrusion 320 and the guide portion 61 on the clamping recess 110 play a guiding role, that is, because the guide portion 61 is inclinedly arranged, the clamping protrusion 320 can smoothly slide along the guide portion 61 on the clamping recess 110, so as to change the relative distance between the first head bead 1 and the second head bead 2, and realize the adjustment of the length of the wearing piece. After the adjustment is completed, the stop portion 62 on the other side of the clamping protrusion 320 and the corresponding stop portion 62 of the clamping recess 110 are matched with each other, so as to limit the sliding of the clamping protrusion 320 in the opposite direction, thereby maintaining the adjusted length.

[0106] It can be understood that the length adjustment structure is integrated into the watchband body, and by operating the length adjustment structure, such as pressing the pressing portion 31 of the execution element 3, the first limiting portion 11 is separated from the second limiting portion 32, that is, the relative positions of the first head bead 1 and the second head bead 2 can be freely changed, and then the length adjustment of the watchband is realized. The whole process is simple and intuitive, and does not need to rely on additional tools.

[0107] In some embodiments, the watchband body generally comprises two bands, one end of one band is stably connected with the first head bead 1, and one end of the other band is connected with the second head bead 2. The other ends of the two bands are connected to a device host of a wearable device, so as to form a complete wearable device.
