Description

Technical Field

[0001] This utility model relates to the technical field of toothbrushes, and in particular to an anti-slip gum-protecting toothbrush. Background Technology

[0002] During toothbrush use, water is frequently encountered. With the lubrication of water, fingers can easily slide on the toothbrush. When brushing, this sliding between the fingers and the toothbrush can cause the point of force to shift, making it difficult for the user to apply sufficient force. This can result in excessive force causing bleeding gums or insufficient force causing inadequate brushing. Therefore, anti-slip toothbrushes are of great importance.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This utility model addresses one of the problems existing in the prior art to a certain extent, as mentioned above. Therefore, one objective of this utility model is to provide an anti-slip gum-protecting toothbrush to improve the anti-slip performance of the brush, optimize the user's brushing experience, and avoid situations where excessive force leads to gum bleeding or insufficient brushing results in inadequate cleaning.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A non-slip gum-protecting toothbrush includes a toothbrush body and a deformable limiting structure disposed on the toothbrush body. The toothbrush body has a pressing side and a back side facing each other, a first groove facing the pressing side, and a second groove communicating with the outside of the first groove. The first groove is located on one side of the deformable limiting structure, and the second groove extends to the outside of the deformable limiting structure. An anti-slip member is disposed in the second groove, and the anti-slip member has an extension portion corresponding to the first groove.

[0006] In the anti-slip gum-protecting toothbrush described above, at least a portion of the inner wall of the first groove is configured as an arc-shaped wall.

[0007] In a non-slip gum-protecting toothbrush as described above, the second groove extends at least partially circumferentially from the pressing side toward the back side along the toothbrush body.

[0008] In the anti-slip gum-protecting toothbrush described above, the second groove extends at least partially along the axial direction of the toothbrush body toward the end of the toothbrush body.

[0009] As described above, in an anti-slip gum-protecting toothbrush, the outer wall of the anti-slip component is provided with anti-slip texture, and the anti-slip texture is at least partially opposite to the extension portion.

[0010] As described above, in an anti-slip gum-protecting toothbrush, the anti-slip component has an outwardly convex wall on the pressing side, the outwardly convex wall has a force-bearing surface corresponding to the extension, the outwardly convex wall has an arcuate tendency, and the inflection point of the outwardly convex wall is located on one side of the force-bearing surface.

[0011] As described above, an anti-slip gum-protecting toothbrush includes a toothbrush body comprising a first handle segment and a second handle segment. A deformation limiting structure is disposed between the first handle segment and the second handle segment, allowing the first handle segment and the second handle segment to change their relative positions. The deformation limiting structure includes a deformable portion and a limiting portion. The deformable portion includes a first connecting portion connected to the first handle segment, a second connecting portion connected to the second handle segment, and an opening disposed between the first connecting portion and the second connecting portion. The opening provides clearance for the relative positional changes between the first handle segment and the second handle segment. The limiting portion is disposed within the opening and connected to the first connecting portion and the second connecting portion. When the opening narrows, the limiting portion supports the first handle segment and the second handle segment to return to their initial positions. The limiting portion has a notch communicating with the opening.

[0012] The anti-slip gum-protecting toothbrush described above further includes a buffer airbag disposed on the toothbrush body. The buffer airbag is located outside the opening. The buffer airbag is sealed to the deformable part or integrally formed with the toothbrush body. The buffer airbag is used to provide resistance when the first handle segment and the second handle segment undergo relative positional changes. A hollow structure is provided between the buffer airbag and the deformable part, and the limiting part is located within the hollow structure.

[0013] As described above, the anti-slip gum-protecting toothbrush further includes a core-pulling hole that passes through the toothbrush body and is located on one side of the first groove. The limiting part is located on one side of the core-pulling hole. The toothbrush body is provided with a partition for sealing the core-pulling hole. The partition is provided with an assembly marking part on the side facing the pressing side.

[0014] As described above, in an anti-slip gum-protecting toothbrush, the separator is detachably connected to the toothbrush body or the buffer airbag. A first snap-fit ​​portion is provided on the side of the separator away from the assembly marking portion, and a second snap-fit ​​portion corresponding to the first snap-fit ​​portion is provided on the toothbrush body or the buffer airbag.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides an anti-slip, gum-protecting toothbrush. The toothbrush body has a pressing side and a back side facing each other, a first groove facing the pressing side, and a second groove communicating with the outside of the first groove. The first groove is located at the pressing position of the user's thumb. The second groove is also provided outside the first groove, and the first groove and the second groove are connected. An anti-slip element is provided in the second groove. The anti-slip element wraps around the outside of the toothbrush body, increasing the friction between the user's hand and the toothbrush, improving the anti-slip performance of the toothbrush, preventing the toothbrush from slipping, and reducing the force required by the user to apply to the toothbrush. The user applies excessive force; the anti-slip component also has an extension that matches the first groove. The first groove increases the space for the toothbrush body to accommodate the anti-slip component. The extension is correspondingly located in the first groove, thereby increasing the thickness of the soft material in the anti-slip component at the thumb pressing position. This optimizes the user's grip on the toothbrush, helps to alleviate the user's awareness of applying force, and thus helps to reduce the user's need to apply force, preventing the user from using excessive force when brushing their teeth, which can easily damage the gums. At the same time, it increases the elasticity and softness of the pressing side, improving the user's grip comfort.

[0016] 2. The toothbrush body is also equipped with a deformation limiting structure. This deformation limiting structure allows the toothbrush body to bend and deform to a certain extent under the reaction force of the teeth. This reduces the pressure of the toothbrush on the teeth to a certain extent, thereby preventing the user from using excessive force when brushing and causing damage to the gums, thus achieving the purpose of protecting the gums. At the same time, the toothbrush body can spring back to its initial position through this deformation limiting structure, which helps to extend the life of the toothbrush and prevents the toothbrush body from being unable to spring back to its original position due to excessive bending and deformation, ensuring the normal use of the toothbrush.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] like Figures 1 to 8 As shown, this utility model provides an anti-slip gum-protecting toothbrush, including a toothbrush body 1 and a deformable limiting structure 2 disposed on the toothbrush body 1. The toothbrush body 1 has a pressing side 101 and a back side 102 facing each other, a first groove 11 facing the pressing side 101, and a second groove 12 communicating with the outside of the first groove 11. The first groove 11 is located on one side of the deformable limiting structure 2, and the second groove 12 extends to the outside of the deformable limiting structure 2. An anti-slip member 3 is disposed in the second groove 12, and the anti-slip member 3 is provided with an extension 31 corresponding to the first groove 11.

[0023] In practical applications, when the toothbrush body 1 is used for brushing teeth, the pressing side 101 faces the human body, and the back side 102 faces away from the human body. When the user holds the toothbrush body 1, the user's thumb can press on the pressing side 101, the user's palm faces the toothbrush body 1, and the user's other fingers can move around the toothbrush body 1 from the pressing side 101 to the back side 102, thus enabling the user to hold the toothbrush body 1 and apply brushing force. When brushing teeth, the user mainly uses the thumb, index finger, and middle finger to clamp the toothbrush body 1, and these three fingers work together. When applying force to the toothbrush body 1, with the remaining fingers resting on the back side 102 of the toothbrush body 1 to stabilize the toothbrush, this invention improves the anti-slip structure of the toothbrush to optimize the force applied by the human body to the toothbrush body 1. A first groove 11 is provided on the pressing side 101, positioned at the pressing position of the human thumb. A second groove 12 is also provided outside the first groove 11, and the first groove 11 and the second groove 12 communicate with each other. The anti-slip element 3 is provided within the second groove 12. The anti-slip element 3 can be made of materials such as silicone or T-shaped silicone. Made of soft materials such as PE, the anti-slip component 3 is adapted to fit the second groove 12. The anti-slip component 3 wraps around the outside of the toothbrush body 1, allowing the user's hand to directly contact it. The anti-slip component 3 increases the friction between the user's hand and the toothbrush, improving the toothbrush's anti-slip performance and preventing slippage, thus reducing the user's need to apply excessive force. Furthermore, the anti-slip component 3 also has an extension 31 adapted to the first groove 11, which increases the resistance of the toothbrush body 1 to the anti-slip material. The sliding part 3 has an accommodating space, and the extension 31 is correspondingly disposed in the first groove 11. This increases the thickness of the soft material in the anti-slip part 3 corresponding to the thumb pressing position, optimizes the user's grip on the toothbrush, helps to alleviate the user's awareness of applying force, and thus helps to reduce the user's need to apply force, avoiding excessive force when brushing teeth, which can easily damage the gums. At the same time, it increases the elasticity and softness of the pressing side 101, improves the user's grip comfort, and makes the user's hand more relaxed when holding the toothbrush, so that they will not unconsciously increase the force as when holding a hard plastic handle.

[0024] In addition, the toothbrush body 1 is also provided with the deformation limiting structure 2. The deformation limiting structure 2 allows the toothbrush body 1 to bend and deform to a certain extent under the reaction force of the teeth, which can reduce the pressure of the toothbrush on the teeth to a certain extent, thereby avoiding excessive force when brushing and causing damage to the gums, thus achieving the purpose of protecting the gums. At the same time, the toothbrush body 1 can spring back to the initial position through the deformation limiting structure 2, which helps to extend the service life of the toothbrush and prevents the toothbrush body 1 from being unable to spring back to the original position due to excessive bending and deformation, thus ensuring the normal use of the toothbrush.

[0025] Further optionally, in actual production, the anti-slip component 3 can be sleeved on the toothbrush body 1, or the anti-slip component 3 can be injection molded onto the toothbrush body 1 through a rubber coating process.

[0026] Alternatively, the first groove 11 is recessed from the pressing side 101 toward the back side 102.

[0027] Optionally, the first groove 11 extends along the axial direction of the toothbrush body 1 in a direction away from the deformable limiting structure 2. The first groove 11 preferably extends toward the end 13 of the toothbrush body, and the second groove 12 covers and communicates with the first groove 11. In practical applications, the human thumb is mostly placed along the axial direction of the toothbrush on the pressing side 101. By extending the first groove 11 toward the end 13 of the toothbrush body, the contact area between the anti-slip part 3 and its extension 31 and the human thumb can be increased, thereby further optimizing the grip comfort of the user's hand.

[0028] In another alternative embodiment of the first groove 11, such as Figure 4 and Figure 5 As shown, at least part of the inner wall of the first groove 11 is set as an arc-shaped wall. By setting the inner wall of the first groove 11 as an arc-shaped wall, the volume of the first groove 11 can be further increased, thereby increasing the volume of the extension 31. Moreover, the arc-shaped wall structure can further fix the extension 31 in the first groove 11, improving the structural stability of the toothbrush. Further optionally, the arc-shaped walls are provided on both opposite sides of the first groove 11.

[0029] In another alternative embodiment of the second groove 12, such as Figure 3 As shown, arrow S1 indicates the circumferential extension direction of the second groove 12. The second groove 12 extends at least partially from the pressing side 101 toward the back side 102 along the circumference of the toothbrush body 1. Specifically, based on the user's grip gesture when brushing, the second groove 12 can extend from the pressing side 101 toward the back side 102 away from the human body, so that the anti-slip member 3 forms an outer edge wrapping portion 301 on the toothbrush body 1, and the outer edge wrapping portion 301 is located on the outside of the toothbrush body 1. This is because when the user holds the toothbrush, the contact area between the user's hand and the outside of the toothbrush body 1 is larger, which helps to increase the contact area between the anti-slip member 3 and the user's hand, thereby increasing the anti-slip area on the toothbrush.

[0030] Alternatively, the second groove 12 may extend from the pressing side 101 toward the back side 102 around the side closer to the human body, so that the anti-slip member 3 simultaneously forms an inner side wrapping portion 302 on the toothbrush body 1. In other words, the second groove 12 may extend to the outer periphery of the deformation limiting structure 2, thereby forming an annular wrapping portion 303 on the anti-slip member 3, which is beneficial to increase the structural stability of the anti-slip member 3 on the toothbrush body 1, thereby extending the service life of the anti-slip member 3.

[0031] In another alternative embodiment of the second groove 12, such as Figure 3 As shown, arrow S2 indicates the axial extension direction of the second groove 12. The second groove 12 extends at least partially along the axial direction of the toothbrush body 1 toward the end 13 of the toothbrush body. Specifically, based on the user's grip gesture when brushing, the side of the second groove 12 away from the human body extends axially toward the end 13 of the toothbrush body. That is, the outer edge wrapping portion 301 can extend axially toward the end 13 of the toothbrush body, which can further increase the contact area between the anti-slip component 3 and the user's hand, thereby increasing the anti-slip area on the toothbrush.

[0032] In another alternative embodiment of the anti-slip component 3, such as Figures 4 to 6 As shown, the outer wall of the anti-slip part 3 is provided with anti-slip texture 32. The anti-slip texture 32 is at least partially opposite to the extension part 31. That is, the anti-slip part 3 is provided with the anti-slip texture 32 at least at the position corresponding to the extension part 31. When the user's thumb presses on the anti-slip texture 32, the friction between the anti-slip part 3 and the user's hand is further increased, which improves the anti-slip performance of the toothbrush. At the same time, the anti-slip texture 32 can accurately locate the position of the extension part 31, ensuring that the user's thumb can press on the extension part 31.

[0033] Further optionally, the outer wall of the anti-slip component 3 is provided with a plurality of spaced-apart recesses, or the outer wall of the anti-slip component 3 is provided with a plurality of spaced-apart protrusions, so that the anti-slip component 3 forms the anti-slip texture 32 with a concave-convex surface.

[0034] In another optional embodiment of the anti-slip component 3, such as Figures 4 to 6 As shown, the anti-slip component 3 has a convex wall 33 located on the pressing side 101. The convex wall 33 has a force-bearing surface 331 corresponding to the extension 31. The force-bearing surface 331 is located outside the extension 31. The convex wall 33 has an arcuate shape, and the inflection point of the convex wall 33 is located on one side of the force-bearing surface 331. Specifically, the convex wall 33 protrudes from the pressing side 101 towards the outside of the toothbrush body 1. The force-bearing surface 331 is the surface on which the user's thumb applies force to the anti-slip component 3 when brushing their teeth. Figure 6 As shown, the convex wall 33 also has an inclined surface 332 on one side of the force-bearing surface 331. The inclined surface 332 and the force-bearing surface 331 have a first preset angle, so that the convex wall 33 has a certain arcuate tendency. The force-bearing surface 331 is roughly parallel to the horizontal plane. By setting the wall of the anti-slip member 3 facing the pressing side 101 as an convex wall 33 with a certain arcuate tendency, and by setting the force-bearing surface 331 and the extension 31 in correspondence, the user can accurately position the force application position of the thumb on the toothbrush, so as to further ensure that the user's thumb can press on the extension 31.

[0035] on the other hand, Figure 3 Another alternative embodiment of the toothbrush is also shown, wherein the toothbrush body 1 includes a first handle segment 14 and a second handle segment 15, and a deformation limiting structure 2 is disposed between the first handle segment 14 and the second handle segment 15, the first handle segment 14 and the second handle segment 15 changing relative position through the deformation limiting structure 2; the deformation limiting structure 2 includes a deformation part 21 and a limiting part 22, the deformation part 21 including a first connecting part 211 connected to the first handle segment 14, a second handle segment 15 connected to the second handle segment 15, and an opening 213 disposed between the first connecting part 211 and the second connecting part 212, the opening 213 being used to provide clearance space for the relative position change between the first handle segment 14 and the second handle segment 15; specifically, a brush head 141 is provided at the end of the first handle segment 14 away from the second handle segment 15, the second handle segment 15 is available for the user to hold, and the first handle segment 14... An opening 213 facing the back side 102 is provided between the 4th and the second handle segment 15, and a first connecting part 211 and a second connecting part 212 opposite to each other are provided on both sides of the opening 213. The first connecting part 211 and the second connecting part 212 have a second preset included angle so that the opening 213 is formed between the first connecting part 211 and the second connecting part 212. In practical applications, the toothbrush body 1 can be made of a hard material with certain bending resilience, such as TPE, polypropylene, or nylon. During brushing, the brush head 141 is subjected to the reaction force of the teeth. At this time, the first connecting part 211 can be narrowed through the opening 213 to bend and deform towards the second connecting part 212 in a direction away from the teeth, so that the first handle segment 14 bends and deforms towards the second handle segment 15 in a direction away from the teeth, thereby reducing the pressure of the toothbrush on the teeth and gums to a certain extent and achieving the purpose of protecting the gums.

[0036] In actual brushing, if the bending deformation between the first handle segment 14 and the second handle segment 15 is too large, the cleaning power of the toothbrush will be greatly reduced, making it difficult to clean the teeth thoroughly. Therefore, in this embodiment, the toothbrush is provided with the limiting part 22 within the opening 213 to limit the deformation range of the deformable part 21. Figure 3 As shown, the limiting part 22 is disposed within the opening 213 and connected to the first connecting part 211 and the second connecting part 212. The limiting part 22 supports the first handle segment 14 and the second handle segment 15 to return to their initial positions when the opening 213 narrows. The limiting part 22 has a notch 221 communicating with the opening 213. Specifically, the limiting part 22 is connected to the first connecting part 211 and the second connecting part 212 and is located within the opening 213. The limiting part 22 has a certain height within the opening 213, and the limiting part 22 has the notch 221 communicating with the opening 213. The notch 221 extends outward from the toothbrush body 1 along the height direction of the limiting part 22. In practical applications, the limiting part 22 can support the first connecting part 211 to spring back. The narrowing of the opening 213 is restricted, thereby limiting the bending deformation of the first connecting part 211 toward the second connecting part 212. At the same time, by providing the notch 221 in the limiting part 22, the notch 221 can provide clearance space for bending deformation between the first connecting part 211 and the second connecting part 212. Meanwhile, by narrowing the notch 221 to limit the degree of bending deformation of the first connecting part 211 and the second connecting part 212, the toothbrush body 1 retains a certain degree of bending deformation performance and rebound recovery performance, thereby ensuring that the toothbrush can achieve its gum protection purpose and ensure normal use of the toothbrush.

[0037] Optionally, at least one limiting part 22 may be provided; for example, one limiting part 22 may be provided, which is located in the middle of the opening 213; or, for example, two limiting parts 22 may be symmetrically provided in the deformable part 21; so as to ensure that the limiting part 22 is subjected to balanced force when brushing teeth, thereby ensuring the limiting part 22's resistance to deformation and resilience to the toothbrush body 1.

[0038] Furthermore, such as Figure 7 As shown, the notch 221 has depth and width. The deformation and rebound performance of the toothbrush body 1 can be improved by adjusting the depth and width of the notch 221, thereby optimizing the tooth cleaning effect and gum protection effect of the toothbrush.

[0039] Further optional, such as Figure 7As shown, there is a third preset included angle A between the two opposite sidewalls in the notch 221. The two opposite sidewalls in the notch 221 can be connected by an arc-shaped connecting section to improve the rebound and reset performance of the limiting part 22, thereby improving the rebound and reset performance between the first handle segment 14 and the second handle segment 15.

[0040] Further optional, such as Figure 3 , 4 As shown in Figure 7, the second groove 12 can extend to the outer periphery of the deformable part 21, that is, the second groove 12 extends to the outer periphery of the first connecting part 211 and the second connecting part 212, so that the anti-slip member 3 is wrapped around the outside of the first connecting part 211 and the second connecting part 212, so as to avoid structural interference between the anti-slip member 3 and the deformable part 21, and ensure that the toothbrush body 1 achieves a certain degree of bending deformation through the deformable part 21, while improving the aesthetics of the toothbrush surface.

[0041] To further improve the rebound and reset performance of the toothbrush body 1, Figure 3 and Figure 4 Another alternative embodiment of the toothbrush is also shown, further comprising a buffer airbag 4 disposed on the toothbrush body 1. The buffer airbag 4 is located outside the opening 213. The buffer airbag 4 is sealed to the deformable part 21 or integrally formed with the toothbrush body 1. The buffer airbag 4 is used to provide resistance when the relative position of the first handle segment 14 and the second handle segment 15 changes. In this embodiment, the buffer airbag 4 can be configured as an airbag structure with an inflation chamber therein, or the buffer airbag 4 can be integrally formed from a soft material such as TPE. The buffer airbag 4 is elastic. The buffer airbag 4 is disposed on the deformable part 21. The buffer airbag 4 can provide resistance to the relative bending deformation of the first handle segment 14 and the second handle segment 15, and at the same time enhance the elasticity of the first handle segment 14 and the second handle segment 15 to rebound and reset, thereby improving the resilience and anti-deformation ability of the toothbrush body 1. Secondly, the opening 213 can be accommodated in the buffer airbag 4 to prevent the user's fingers from entering the opening 213 when holding the toothbrush and affecting the bending deformation of the toothbrush body 1, ensuring the bending deformation of the toothbrush and realizing its gum protection performance, and also helping to improve the aesthetic appearance of the toothbrush.

[0042] Furthermore, a hollow structure 5 is provided between the buffer airbag 4 and the deformable part 21, and the limiting part 22 is located within the hollow structure 5. Specifically, the hollow structure 5 can be configured as a hollow cavity. The hollow structure 5 can be located within the buffer airbag 4 or within the deformable part 21. The opening 213 communicates with the hollow structure 5, and the limiting part 22 is located between the opening 213 and the hollow structure 5. The hollow structure 5 can increase the bending deformation space of the deformable part 21, thereby improving the deformation performance and stability of the toothbrush body 1 and further improving the gum protection effect of the toothbrush.

[0043] Figure 3 and Figure 4 Another alternative embodiment of the toothbrush is also shown, wherein the deformable limiting structure 2 further includes a core-pulling hole 6 passing through the toothbrush body 1 and located on one side of the first groove 11, the limiting part 22 is located on one side of the core-pulling hole 6, and the toothbrush body 1 is provided with a partition 7 for sealing the core-pulling hole 6; the partition 7 is provided with an assembly marking part 71 on the side facing the pressing side 101. Specifically, when the toothbrush body 1 and the buffer airbag 4 are integrally injection molded, since the buffer airbag 4 needs to adopt a hollow structure 5, a core-pulling hole 6 is provided on the deformed part 21 to form an air storage space within the deformed part 21. The separator 7 is independently set from the toothbrush body 1 and is detachably installed on the toothbrush body 1 or the buffer airbag 4. The separator 7 is located on one side of the deformed part 21. The separator 7 blocks the core-pulling hole 6 to prevent injection molding material from entering the air storage space when the buffer airbag 4 is injection molded. In addition, in order to facilitate the quick assembly of the separator 7, an assembly marking part 71 is provided on the outer surface of the separator 7. The assembly marking part 71 can be represented as an installation direction arrow. The assembly marking part 71 guides the production personnel to install the separator 7 in the toothbrush body 1 or the buffer airbag 4 in a preset direction to prevent incorrect assembly of the separator 7.

[0044] Figure 8 Another optional embodiment of the toothbrush is shown, wherein the separator 7 is detachably connected to the toothbrush body 1 or the buffer airbag 4. A first snap-fit ​​portion 72 is provided on the side of the separator 7 away from the assembly marking portion 71, and a second snap-fit ​​portion 16 corresponding to the first snap-fit ​​portion 72 is provided on the toothbrush body 1 or the buffer airbag 4. Further optionally, the first snap-fit ​​portion 72 can be configured as a barb portion, and the separator 7 has two opposing barbs on the side facing the buffer airbag 4. The second snap-fit ​​portion 16 can be correspondingly configured as a snap-fit ​​block or latch corresponding to the barbs. By the corresponding snap-fit ​​of the first snap-fit ​​portion 72 and the second snap-fit ​​portion 16, the separator 7 is installed on the toothbrush body 1 or the buffer airbag 4. The structure is simple and easy to install.

[0045] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
