In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0020] Please refer to Figures 1 to 6 , the sliding rod nested structure of the embodiment of the present utility model includes a sliding rod kit 1, a sliding rod insert 2, and a massage head 3. The sliding rod insert 2 is fixedly connected inside the sliding rod kit 1, and the massage head 3 is coaxially and detachably connected to the sliding rod insert 2, preferably by threaded connection, which is not limited herein.

[0021] In the above embodiments, the slide bar kit 1 and the slide bar insert 2 are manufactured separately. The slide bar insert 2 is made of plastic material, and this choice greatly facilitates the processing process. The plastic material has good plasticity and processability, making it simple and fast to machine various complex connection structures on the insert, thereby reducing the processing cost.

[0022] Secondly, since both the slide bar insert 2 and the massage head 3 are made of plastic material, their connection is tighter. Similar material properties enable good sealing and fitting between the two at the contact surface, reducing the problems of gaps and looseness caused by material differences. This tight connection not only improves the overall stability of the massage device but also ensures the uniform transmission of force during the massage process, bringing a more comfortable and effective massage experience to the user.

[0023] In addition, although the slide bar insert 2 is made of plastic material, the slide bar kit 1 is made of metal material to ensure the overall strength of the structure. The high strength and corrosion resistance of the metal material enable the slide bar kit 1 to withstand various forces during the massage process without being easily damaged, thus ensuring the long-term service performance and safety of the massage device.

[0024] In summary, the design of the slide bar nested structure facilitates processing and reduces costs while ensuring the tightness of the connection and the strength of the structure.

When the massage head 3 is screwed into the slide bar insert 2, the internal and external threads are tightly engaged to form a firm connection. This connection method is not only simple and reliable but also convenient for disassembling and replacing the massage head 3, improving the maintainability and flexibility of the device.

[0027] Please refer to Figures 1 to 6 , in another embodiment, the slide bar kit 1 includes a shock-absorbing sleeve 11, a sliding sleeve 12, and a slide bar bracket 13. An annular fitting groove 111 is provided inside the shock-absorbing sleeve 11, and the annular fitting groove 111 is adapted to the sliding sleeve 12, and the sliding sleeve 12 is sleeved on the slide bar bracket 13.

[0028] In the above embodiment, the shock-absorbing sleeve 11 is designed with an annular adapter groove 111, the shape and size of which precisely match the outer contour of the sliding sleeve 12, ensuring that the two can fit tightly. The sliding sleeve 12 is further sleeved on the slide rod bracket 13, and realizes relative movement with the bracket through sliding fit. This nested design not only enhances the integrity of the structure, but also effectively absorbs the vibration and impact force that may be generated during the massage process through the shock-absorbing sleeve 11, thereby improving the user's comfort. At the same time, the sliding connection between the sliding sleeve 12 and the slide rod bracket 13 provides a smooth sliding track for the massage head 3, ensuring the flexibility and accuracy of the massage action.

[0029] See also Figures 1 to 6 In another embodiment, the sliding rod bracket 13 is provided with a retaining hole 131, and the sliding sleeve 12 insert is provided with a retaining column 21, and the retaining column 21 is provided with a threaded hole 211, wherein when the sliding sleeve 12 insert is provided on the sliding rod bracket 13, the retaining column 21 is embedded in the retaining hole 131.

[0030] In the above embodiment, the insert of the sliding sleeve 12 is equipped with a retaining column 21, and the retaining column 21 is provided with a threaded hole 211 to cooperate with a fastener (such as a screw). When the insert of the sliding sleeve 12 is installed on the slide rod bracket 13, the retaining column 21 is accurately aligned and embedded in the retaining hole 131 to form a preliminary axial positioning. Subsequently, the fastener passes through the threaded hole 211 of the insert of the sliding sleeve 12 and is screwed into the slide rod bracket 13 or the corresponding fixing structure to achieve a firm connection between the insert of the sliding sleeve 12 and the slide rod bracket 13. This design not only simplifies the installation process, but also ensures the stability and reliability of the insert of the sliding sleeve 12 on the slide rod bracket 13, providing a solid foundation for the smooth sliding of the massage head 3.

[0031] See also Figures 1 to 6 In another embodiment, the slide bar assembly 1 is made of metal, and the slide bar insert 2 is made of plastic.

[0032] In the above embodiment, specifically, the slide bar set 1 is made of metal material, which provides a stable support frame and a durable foundation for the entire structure by utilizing its high strength, corrosion resistance and good thermal conductivity. The selection of metal material ensures that the slide bar set 1 is not easily deformed or damaged when subjected to various forces during the massage process, thereby ensuring the long-term performance of the device.

[0033] In contrast, the slide bar insert 2 is made of plastic material, which has good machinability, light weight and cost-effectiveness, and is convenient for machining complex connection structures and details on the insert.
