A lightweight, ductile coupling strut

Abstract

This application relates to the field of daily necessities, specifically to a lightweight, resilient coupling support strip, which is composed of a support strip body including a lifting section, a flexible section, and a tail section. The flexible section is located in the middle of the support strip body, with the lifting section and tail section located on either side of the flexible section. The flexible section is divided into a bending section and a compression section, both of which have grooves. The grooves in the compression section and the bending section are staggered, with the grooves in the compression section being deeper than those in the bending section. The groove depth gradually decreases towards both sides, centered on the maximum bending position of the knee joint. During bending, the deep and shallow grooves cooperate, and when the knee joint bends to a threshold angle, the groove structure generates resistance feedback, helping the user control a reasonable range of motion and avoid excessive bending injury. The bending pressure difference generated by the force on both sides of the grooves can adjust the fit in real time, achieving dynamic correction during movement. The thickness difference in the lifting section facilitates gripping with fingers and transmitting pulling force during wear, improving wearing efficiency.

Description

Technical Field

[0001] This application relates to the field of daily necessities, specifically to a lightweight and resilient coupling support strip. Background Technology

[0002] As a core component of the human musculoskeletal system, the knee plays a vital role in supporting the body and coordinating limb movements. It is also one of the most structurally complex joints and carries the highest risk of injury. The core value of knee braces lies in providing protection for the knees during daily activities and sports, reducing the impact and damage to the knee joint caused by improper movements or force application.

[0003] Most mainstream sports knee braces on the market today feature support strips on both sides of the knee joint. This structure provides cushioning and support during knee movements such as squatting and standing, effectively protecting against knee injuries. However, existing support strips generally have design limitations: firstly, their thickness makes the knee brace feel bulky; secondly, their cushioning is rather stiff, lacking a snug fit and elasticity. These two issues not only directly affect wearing comfort but may also restrict the range of motion of the knee joint, reducing flexibility during exercise. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a lightweight and flexible coupling support strip, the specific technical solution of which is as follows:

[0005] This application provides a lightweight and flexible coupling support strip, characterized in that it is composed of a support strip body, the support strip body including: a lifting section, a flexible section and a tail section; the flexible section is located in the middle of the support strip body, and the lifting section and the tail section are respectively located on both sides of the flexible section; the flexible section is divided into a bending section and a compression section, and both the bending section and the compression section have grooves, with the grooves of the compression section and the grooves of the bending section being staggered.

[0006] In one specific embodiment of this application, the compression groove is deeper than the bending groove.

[0007] In one specific embodiment of this application, the lifting section is composed of a connecting part and a handle, the connecting part and the handle having different thicknesses; the connecting part is extended from a flexible section, and the thickness of the connecting part decreases as it moves further away from the flexible section.

[0008] In one specific embodiment of this application, the compression groove in the center of the flexible section is the deepest, and the compression groove gradually becomes shallower as it extends toward the lifting section and the tail section.

[0009] In one specific embodiment of this application, the lifting section has a hollowed-out area.

[0010] In one specific embodiment of this application, the opening length of the compression groove and the bending groove in the flexible section that are furthest from the lifting section is the longest, and the opening length of the compression groove and the bending groove gradually shortens as it extends toward the lifting section.

[0011] In one specific embodiment of this application, the groove depth in the compression section is 2 to 6 mm, and the groove depth in the bending section is 0.05 to 1.50 mm.

[0012] In one specific embodiment of this application, the opening length of the groove is 0.1 to 3.0 mm.

[0013] In one specific embodiment of this application, the thickness of the flexible segment is the thickest at the middle of the length of the flexible segment, and the thickness of the compression part and the bending part are also different. As it extends towards the lifting section and the tail section, the thickness gradually becomes thinner.

[0014] In one specific embodiment of this application, the thickness of the flexible segment is 0.5 to 4.5 mm.

[0015] In one specific embodiment of this application, the width of the flexible segment is 6 to 18 mm.

[0016] This application has the following beneficial technical effects:

[0017] This application provides a lightweight, flexible coupling support strip. Centered on the maximum bending position of the knee joint, the groove depth gradually decreases towards both sides. During bending, the deep and shallow grooves work together. When the knee joint bends to a threshold angle, the groove structure generates resistance feedback, helping the user control a reasonable range of motion and avoid over-bending. The bending pressure difference generated by the forces on the two grooves allows for real-time adjustment of the support strip's fit to the knee joint, achieving dynamic correction during movement. Furthermore, the difference in material thickness at the upper end of the support strip enhances the tactile feel when gripping, facilitating finger gripping and force transmission during wear, thus improving wearing efficiency.

[0023] It should be noted that certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that different terms may be used to refer to the same component. This specification and claims do not distinguish components based on differences in terminology, but rather on differences in function. The terms "comprising" or "including" used throughout the specification and claims are open-ended and should be interpreted as "comprising but not limited to." The following descriptions in the specification are preferred embodiments for carrying out this application; however, these descriptions are for the purpose of understanding the general principles of the specification and are not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0024] This application provides a lightweight and flexible coupling support strip, which is composed of a support strip body 1. The support strip body is integrally formed and is divided into a lifting section 11, a flexible section 12 and a tail section 13. The lifting section 11 and the tail section 13 are located on both sides of the flexible section 12.

[0025] In one specific embodiment of this application, the material of the support strip body 1 is synthetic plastic, such as thermoplastic polyurethane (TPU), thermoplastic polyester elastomer (TPEE), thermoplastic olefin elastomer (TPO), and thermoplastic silicone elastomer (TPSIV).

[0026] In one specific embodiment of this application, the above-mentioned lightweight and flexible coupling support bar has a flexible segment 12 divided into a bending portion 121 and a compression portion 122.

[0027] In one specific embodiment of this application, both the bending portion 121 and the compression portion 122 have grooves, and the grooves of the compression portion 122 and the bending portion 121 are staggered. The staggered arrangement of grooves avoids stress concentration at the connection points of symmetrical grooves, as is common with oppositely arranged grooves, thus preventing cracking of the support strip along weak areas that may occur with long-term use. The staggered arrangement of grooves also distributes stress to different areas, reducing the load on a single location and extending the service life of the support strip. Simultaneously, the staggered grooves are equivalent to constructing an "asymmetric support unit" within the support strip: for example, when the support strip on the side of the knee joint is subjected to lateral impact, the staggered grooves can form an "interlocking effect" through the protrusions at different positions on both sides, preventing excessive deformation of the support strip to one side. Compared to the "symmetrical deformation" of oppositely arranged grooves, this provides more stable control over joint displacement (e.g., preventing knee valgus). The staggered grooves can also create a "flexible transition section" on the surface of the support strip through their misaligned distribution. For example, the staggered grooves in a running knee brace can slightly deform at different positions according to the contraction rhythm of the quadriceps muscle, always conforming to the leg contour and preventing the support strip from slipping or developing localized indentations.

[0028] In one specific embodiment of this application, the groove of the compression portion 122 is deeper than the groove of the bending portion 121. In this application, the deeper groove of the compression portion 122 than the groove of the bending portion 121 should be understood as the shallowest depth of the groove of the compression portion 122 being greater than the deepest depth of the groove of the bending portion 121. During knee joint movement (such as flexion, extension, and slight rotation), the skin, fascia, and muscles (such as the hamstrings) in the popliteal fossa region undergo greater stretching and folding—the popliteal fossa skin folds and accumulates during knee flexion and fully unfolds during knee extension, with a deformation range far greater than that of the outer side of the knee joint. If the grooves in the bending section 121 and the compression section 122 are of equal depth, a shallower groove will restrict the deformation of the popliteal fossa area, causing a pulling sensation or bending stiffness between the support strip and the skin. A deeper groove in the compression section 122 provides more ample "deformation buffer space," allowing the support strip to flexibly adapt to the folding or unfolding of the popliteal fossa without hindering normal knee joint movement. This is especially suitable for sports requiring frequent knee flexion and extension, such as running and squatting. The support strip of the knee brace must simultaneously meet the dual requirements of impact resistance and anti-deviation on the outer side, and pressure resistance and comfort on the popliteal side. A shallower groove in the bending section 121 reduces the directional stress generated when the support strip bends, resulting in a larger and more reasonable bending arc. A deeper groove in the compression section 122, on the other hand, effectively provides flexibility to this area through "structural weakening," preventing the support strip from compressing the popliteal fossa due to excessive rigidity, while not affecting the overall support frame. This ensures both the protective strength on the outer side and addresses the comfort issues on the popliteal side.

[0029] In this application, the location of the groove is described in various ways, such as a compression groove, a bending groove, a compression groove, a bending groove, etc. It should be understood that these descriptions are intended to describe the location of the groove and are not related to whether they specifically refer to a particular groove.

[0030] In this application, the depth of a groove refers to the straight-line length of the groove from the edge of the flexible segment to the center of the flexible segment; for example, the groove depth of a groove in a bend refers to the straight-line distance from the edge of the bend to the edge of the compression segment; similarly, the groove depth of a groove in a compression segment refers to the straight-line distance from the edge of the compression segment to the edge of the bend segment. It should be understood that comparing groove depths in this application is equivalent to comparing the numerical values ​​of the aforementioned straight-line distances.

[0031] In this application, when describing the length of the support bar body 1 or the flexible segment 12, it can be regarded as the length of the lifting segment 11 from the tail segment 13, and the width is the vertical length from one edge of the support bar body 1 or the flexible segment 12 to the other edge.

[0032] In this application, the term "interlaced" used to describe the arrangement of the grooves can also be understood as "interlaced," that is, a groove of a curved part 121 is "sandwiched" between the grooves of two compression parts 122, or a groove of a compression part 122 is "sandwiched" between the grooves of two curved parts 121.

[0033] In one specific embodiment of this application, the lifting section 11 is fan-shaped and is composed of a connecting part 111 and a handle 112. More specifically, the fan shape is a "sector-like shape" with one end being an arc and the other end being a vertical right-angled side.

[0034] In this application, "opening length" describes the length missing along the edge of the flexible segment caused by an opening.

[0035] In this application, the flexible segment 12 serves as the main functional segment in the implementation of the solution, primarily relying on the setting of the groove depth, groove design, and opening length; while the setting of the flexible segment length is aimed at adapting to the individual differences of different users. Due to objective differences in the physical conditions (such as leg length) of different users, it is not convenient to arbitrarily fix the length of the flexible segment.

[0036] In this application, the length of the flexible segment 11 accounts for 70% to 85% of the length of the support strip body 1.

[0037] In one specific embodiment of this application, the connecting portion 111 and the handle 112 have different thicknesses. Since the connecting portion 111 is extended from the flexible segment 12, the thickness of the connecting portion 111 decreases as it moves further away from the flexible segment 12. The narrowest part of the connecting portion 111 is 0.5 to 1.5 mm, for example, it can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.35 mm, 1.4 mm, 1.45 mm, or 1.5 mm. Furthermore, the thickness of the handle 112 is 3 to 5 mm, for example, it can be 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, or 5 mm.

[0038] In one specific embodiment of this application, a hollow area is provided in the lifting section 11. Specifically, the hollow area is located in the connecting part 111. This application does not limit the shape and size of the hollow area, and it can be adjusted according to the user's needs while meeting the requirements of structural strength and material strength.

[0039] In one specific embodiment of this application, both the bending portion 121 and the compression portion 122 have grooves. The grooves in the compression portion 122 and the bending portion 121 are deepest at the center of the flexible segment 12, gradually becoming shallower as they extend towards the lifting segment 11 and the tail segment 13. When the knee joint performs flexion and extension movements (such as running or squatting), the area of ​​most severe deformation corresponds to the position near the popliteal fossa at the center of the flexible segment: when the knee is flexed, the skin folds most severely at the center of the popliteal fossa (corresponding to the compression portion 122), and the muscle stretch is greatest at the center of the outer side of the knee (corresponding to the bending portion 121). The deformation gradually decreases as it extends to both sides. If the deepest point of the groove is not in the center, it will result in insufficient buffer space in the area of ​​greatest deformation. For example, if the central groove is too shallow, the support bar will compress the skin behind the knee when the knee is bent, and pull on the outer muscles when the knee is extended. The design of this application can provide sufficient deformation redundancy space in the central area where the deformation is most intense, while the shallow grooves on both sides can accommodate small deformations, allowing the support bar to deform synchronously with the movement of the knee joint.

[0040] In one specific embodiment of this application, the groove depth of the compression part 122 is 2 to 6 mm, for example, it can be 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, 5 mm, 5.1 mm, 5.2 mm, 5.3 mm, 5.4 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm, or 6 mm.

[0041] In one specific embodiment of this application, the groove depth of the bent portion 121 is 0.05 to 1.50 mm, for example, it can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.35 mm, 1.4 mm, 1.45 mm, or 1.5 mm.

[0042] In one specific embodiment of this application, the width of the flexible segment 12 varies, with the width being the narrowest at the midpoint of the length of the flexible segment 12, and gradually widening as it extends toward the lifting segment 11 and the tail segment 13.

[0043] In one specific embodiment of this application, the width of the flexible segment 12 is 6 to 18 mm, for example, it can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm, 13 mm, 13.5 mm, 14 mm, 14.5 mm, 15 mm, 15.5 mm, 16 mm, 16.5 mm, 17 mm, 17.5 mm, or 18 mm.

[0044] In one specific embodiment of this application, the thickness of the flexible segment 12 is thickest at the midpoint of its length, gradually decreasing in thickness as it extends towards the lifting segment 11 and the tail segment 13. In another specific embodiment, the thicknesses of the compression portion 122 and the bending portion 121 differ; the maximum thickness of the compression portion 122 is less than the maximum thickness of the bending portion 121, and the minimum thickness of the compression portion 122 is less than or equal to the minimum thickness of the bending portion 121. In summary, the midpoint of the flexible segment 12 typically corresponds to the core stress location of a human joint or muscle, and is the concentrated area of ​​muscle tension and external force impact during flexion and extension. A thicker segment provides the flexible segment 12 with greater structural rigidity and cushioning capacity. From a support perspective, this design better resists lateral impact forces during movement and limits excessive joint movement; from a cushioning perspective, the thicker material can absorb more local pressure through its own deformation, reducing direct stress on bones and soft tissues and playing a role in pressure dispersion. If the thickness of the middle section is insufficient, the support of the core stress area will be weak, losing the core protective value of the flexible segment. The lifting section 11 typically serves to fix the structure, connect, or hold; the tail section 13 is used to conform to the limb's end or transition into the skin, its core function being connection, fixation, and adaptation to limb movement and deformation, rather than bearing primary support. The thinner thickness of the lifting section 11 reduces rigidity at the connection point, making it easier to fix and conform to other protective gear, while reducing the feeling of foreign objects during connection; the thinner thickness of the tail section 13 improves the fit to the limb's end (such as the lower leg), avoiding edge lifting or movement jamming caused by excessive thickness (e.g., if the tail section is too thick when bending the knee, it can easily pull on the calf muscles, affecting the range of motion). This design allows the flexible section 122 to precisely allocate material between core protection and auxiliary connection functions, avoiding functional redundancy and decreased experience caused by excessive thickness at both ends.

[0045] In one specific embodiment of this application, the thickness of the flexible segment is 0.5 to 4.5 mm, for example, it can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, or 4.5 mm.

[0046] In one specific embodiment of this application, the thickness of the compression portion 122 is 0.5 to 3.5 mm, for example, it can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, or 3.5 mm.

[0047] In one specific embodiment of this application, the thickness of the bent portion 121 is 1 to 4.5 mm, for example, it can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, or 4.5 mm.

[0048] In one specific embodiment of this application, the opening length of the groove is 0.1 to 3 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0049] In this application, the shape of the tail segment 13 is not specifically limited and can be any shape. However, in view of product complexity and production cost, common shapes are often selected, such as rectangles, rounded rectangles, semicircles, triangles and sectors.

[0050] In one specific embodiment of this application, the dimensions of the tail segment 13 are not specifically limited; its width may be wider than the connection point with the flexible segment 12, or it may be the same as the connection point with the flexible segment 12. Furthermore, the length of the tail segment 13 can also be adjusted accordingly according to user requirements.

[0051] In one specific embodiment of this application, the width of the flexible section 12 gradually narrows from near to far from the lifting section 11; the groove depths provided in the compression section 122 and the bending section 121 remain consistent. From near to far from the lifting section 11, the opening length of the groove in the compression section 122 gradually increases; the opening length of the groove in the bending section 121 gradually increases.

[0052] In this application, due to the unavoidable accuracy deviations during the technical implementation process, the values ​​in the various numerical related technical solutions of this application that differ from each value by no more than ±0.2mm still meet the numerical requirements described in this application and can be regarded as being within a reasonable error range, without affecting the substantive implementation and effect of the technical solution.

[0053] The following will detail the various lightweight and flexible coupling support strips provided in this application in the embodiments. It should be understood that all descriptions of the shape, structure and features of the lightweight and flexible coupling support strips do not specifically refer to the manufacturing process or assembly and fixing method of the structure, but are merely simplified descriptions of complex shapes in a way that is easy to understand.

[0054] Example 1

[0055] This embodiment provides a lightweight, flexible coupling support strip, the structure of which is as follows: Figure 1The diagram shows a support strip body 1, which is made of thermoplastic polyurethane (TPU) and is integrally molded, with a length of 26cm. The support strip body 1 includes a lifting section 11, a flexible section 12, and a tail section 13. The flexible section 12 is located in the middle of the support strip body 1, with the lifting section 11 and tail section 13 located on either side of the flexible section 12. The lifting section 11 is fan-shaped and consists of a connecting part 111 and a handle 112. The distance between the end of the flexible section 12 closest to the connecting part 111 and the end of the lifting section 11 furthest from the flexible section 12 is 45mm. The connecting part 111 and the handle 112 have different thicknesses. The connecting part 111 extends from the flexible section 12, and its thickness decreases as it moves further away from the flexible section 12. The narrowest point of the connecting part 111 is 1mm, and the handle 112 is 4mm thick. A hollowed-out area is also provided in the lifting section 11. The width of the flexible segment 12 varies, being narrowest at the midpoint of its length at 7.3 mm. It gradually widens as it extends towards the lifting segment 11 and the tail segment 13, reaching a maximum width of 15 mm. The thickness of the flexible segment 12 is thickest at the midpoint of its length. The thicknesses of the compression section 122 and the bending section 121 also differ, with the compression section 122 being the thickest at 3 mm and the bending section 121 being the thickest at 4 mm. The thickness gradually decreases as it extends towards the lifting segment 11 and the tail segment 13. The flexible segment 12 is divided into a bending section 121 and a compression section 122. The compression section 122 has a groove, with the deepest groove (3 mm) located at the midpoint of the flexible segment's length. The groove depth gradually decreases as it extends towards the lifting segment 11 and the tail segment 13, reaching a minimum depth of 0.5 mm. The bending section 121 is also provided with grooves. The groove located near the midpoint of the flexible section 12 is the deepest, at 1.3 mm. As the groove in the bending section 121 extends towards the lifting section 11 and the tail section 13, the depth of the groove gradually decreases, reaching a minimum of 0.5 mm. The grooves in the bending section 121 and the grooves in the compression section 122 are staggered. The tail section 13 is semi-circular.

[0056] Example 2

[0057] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the depth and opening method of the groove are different, the style of the flexible section 12 is different, the size of the tail section 13 is smaller, and the lifting section 11 does not have a hollow area.

[0058] In this embodiment, the width of the flexible segment 12 gradually narrows from near to far from the lifting segment 11, with a maximum width of 15mm and a minimum width of 6.8mm, and a width of 7mm at the midpoint of the flexible segment 12's length. The groove depths in the compression section 122 and the bending section 121 remain consistent, with the compression section 122 having a groove depth of 3.5mm and the bending section 121 having a groove depth of 1.3mm. Simultaneously, from near to far from the lifting segment 11, the opening length of the groove in the compression section 122 gradually increases, with a maximum length of 3.2mm and a minimum length of 0.8mm; the opening length of the groove in the bending section 121 also gradually increases, with a maximum length of 2.4mm and a minimum length of 0.8mm. The tail segment 13 is smaller, and its width is consistent with the narrowest point of the flexible segment 12.

The specific embodiments described above are merely illustrative and instructive, not restrictive. Those skilled in the art can make many other forms based on the guidance of this specification and without departing from the scope of protection of the claims of this application, and these are all within the scope of protection of this application.
