[0027] like Figure 5 As shown, the surface decorative layer 2 includes a primer layer 12, a middle coat layer 13, and a topcoat layer 14. The primer layer 12 is coated on the outer surface of the substrate 1. The middle coat layer 13 is disposed on top of the primer layer 12 and contains pigment particles to form a specific pattern. The topcoat layer 14 covers the middle coat layer 13 and is polished to form a smooth surface. The coating design of the primer layer 12 enhances the adhesion between the surface decorative layer 2 and the substrate 1, preventing the paint coating from peeling off during use. The pigment particle design of the middle coat layer 13 gives the handle a unique artistic value and visual appeal, further enhancing the user experience. The polishing design of the topcoat layer 14 improves the surface smoothness of the handle, making it more ergonomic.

[0028] In the specific implementation process, the base material 1 is manufactured using 3D printing technology. Its internal cavity 3 and reinforcing ribs 4 not only reduce the overall weight but also improve structural strength, making the handle more durable. The outer surface of the base material 1 features multiple grooves and protrusions. These structures not only increase friction when the user grips the handle but also stimulate acupoints on the user's palm and promote blood circulation. The introduction of the adjustment module 5 allows users to flexibly adjust the shape and size of the handle according to their own needs, meeting the personalized requirements of different users. The design of the connection module 6 ensures the stability of the handle during use, preventing it from loosening or falling off due to vibrations from external equipment or supports. The multi-layered structure of the surface decorative layer 2, combined with lacquer craftsmanship, gives the handle unique artistic value and visual appeal, further enhancing the user experience.

[0029] The mounting holes of the tire body substrate 1 are connected to the fixing seat 9 via a threaded structure. This design allows for quick assembly and disassembly of the fixing seat 9 with the tire body substrate 1, improving the assembly efficiency of the handle. The snap-fit ​​structure of the fixing seat 9 ensures the stability of the connection between it and the tire body substrate 1, preventing loosening or detachment during use. The locking element 10 is connected to the fixing seat 9 via bolts. This design ensures the stability of the handle during use, preventing loosening or detachment due to vibrations from external equipment or supports. The sliding connection design of the adjusting rod 7 allows users to flexibly adjust the shape and size of the handle according to their needs, meeting the personalized requirements of different users. The anti-slip texture design of the limiting block 8 prevents loosening after adjustment, ensuring the stability of the handle during use.

[0030] The primer layer 12 of the surface decorative layer 2 is applied to the outer surface of the base material 1. This design enhances the adhesion between the surface decorative layer 2 and the base material 1, preventing the paint coating from peeling off during use. The intermediate paint layer 13 is applied over the primer layer 12 and contains pigment particles to form specific patterns. This design gives the handle a unique artistic value and visual appeal, further enhancing the user experience. The topcoat layer 14 covers the intermediate paint layer 13 and is polished to form a smooth surface. This design improves the surface smoothness of the handle, making it more ergonomic.

[0031] The outer surface of the base material 1 features multiple grooves and raised structures. These structures not only increase friction when the user grips the handle but also stimulate acupoints on the user's palm and promote blood circulation. The internal cavity 3 and reinforcing ribs 4 of the base material 1 reduce overall weight and increase structural strength, making the handle more durable. The introduction of the adjustment module 5 allows users to flexibly adjust the shape and size of the handle according to their needs, meeting the personalized requirements of different users. The design of the connection module 6 ensures the stability of the handle during use, preventing it from loosening or falling off due to vibrations from external equipment or supports. The multi-layered structure of the surface decorative layer 2, combined with lacquer craftsmanship, endows the handle with unique artistic value and visual appeal, further enhancing the user experience.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle of this utility model is provided in conjunction with specific application scenarios.

[0033] First, when using the handle, the user needs to adjust its shape and size according to their individual hand size and grip habits. By rotating the adjusting rod 7, it slides along the inner wall of the base material 1, thereby changing the overall length or curvature of the base material 1. The sliding connection design of the adjusting rod 7 ensures its flexible movement, while the limiting block 8 is fixedly connected to the adjusting rod 7 through a threaded structure and prevents loosening with anti-slip texture. After adjustment, the position of the limiting block 8 is locked, ensuring that the handle maintains a stable shape during subsequent use. This process realizes personalized adjustment functionality to meet the rehabilitation needs of different users.

[0034] Secondly, the handle assembly is completed via the connecting module 6. The mounting base 9 is quickly connected to both ends of the tire body substrate 1 via a snap-fit ​​structure. This design simplifies the assembly process and improves assembly efficiency. Subsequently, the locking component 10 is connected to the mounting base 9 via bolts, firmly fixing the handle to the external equipment or bracket. The bolt connection design of the locking component 10 ensures that the handle will not loosen or fall off due to external vibrations during use, thus guaranteeing stability in use.

[0035] During use, the grooves and protrusions on the outer surface of the base material 1 play a crucial role. The grooves are spaced apart along the circumferential direction of the base material 1, increasing friction when the user grips it and preventing hand slippage; the protrusions stimulate acupoints on the palm, promoting local blood circulation. These designs not only improve grip comfort but also enhance the functionality of the handle in cognitive rehabilitation training. Furthermore, the cavity 3 inside the base material 1 is filled with an elastic material 11, such as silicone or polyurethane foam, which absorbs impact and further improves the user experience. Reinforcing ribs 4 are evenly distributed along the axial direction of the base material 1, enhancing the overall structural strength and preventing deformation due to long-term use.

[0036] The design of the surface decorative layer 2 also embodies a combination of functionality and aesthetics. The primer layer 12 is applied to the outer surface of the base material 1, enhancing the adhesion between the lacquer coating and the base material 1, preventing peeling after long-term use. The intermediate lacquer layer 13 contains pigment particles that form specific patterns, giving the handle a unique artistic value and enhancing its visual appeal. The topcoat layer 14, after polishing, forms a smooth surface, further improving the tactile feel and ergonomic adaptability of the handle.

[0037] Finally, in practical applications, such as cognitive rehabilitation training, users can fix the handle to the rehabilitation equipment, adjust it to a suitable shape and size using the adjustment module 5, and then begin training movements such as grasping and rotating. The lightweight design of the substrate 1 reduces user fatigue from prolonged holding, while the artistic aesthetics of the surface decorative layer 2 enhance user interest and psychological pleasure. Throughout the process, the structural design and functional optimization of the handle work together to improve the rehabilitation effect.

[0038] The above description is only one specific embodiment of this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
