This application provides a massager, including a first body, a second body, and a flipping assembly. The first body includes a support portion and a first connecting portion protruding from the support portion. The second body includes a second connecting portion and a massage portion disposed on the second connecting portion. The second connecting portion is rotatably connected to the first connecting portion, and a sliding groove is formed along its thickness direction in the second connecting portion. The flipping assembly includes a motor and an eccentric member. One end of the eccentric member is disposed on the output shaft of the motor, and the other end extends into the sliding groove. The second connecting portion has a first stop surface and a second stop surface at the opening of the sliding groove to stop the eccentric member, and the included angle between them is 25°-35°.

Description

Technical Field

[0001] This application relates to the field of massage equipment, and more particularly to a massager. Background Technology

[0002] In existing massager designs, to achieve the kneading effect during massage, a segmented design is typically used, meaning different parts of the massager can rotate or move relative to each other. The basic principle of this design is to simulate the movements of a human hand during massage, such as kneading and pinching, to relax muscles and relieve fatigue. However, when massaging the lower back, existing massagers have some shortcomings in the design of their rotation amplitude. On the one hand, some massagers have a rotation amplitude designed too small, resulting in almost no noticeable rotation effect during use, thus failing to effectively relax muscles or relieve fatigue. Users may feel that the massage intensity is insufficient and fails to achieve the desired effect. On the other hand, other massagers have a rotation amplitude designed too large, which can lead to excessive pressure on muscles during massage, even deviating from the user's desired massage location. Excessive pressure can not only cause discomfort but also potentially damage muscles. Furthermore, if the massager deviates from the target position during rotation, the massage effect will be significantly reduced.

[0003] Therefore, designing a massager with a relatively moderate rotation range, which ensures sufficient massage strength and effect while avoiding excessive pressure on muscles or deviation from the target position, is key to improving the user experience. Utility Model Content

[0004] In view of this, it is necessary to provide a massager with a relatively moderate rotation range, which can ensure sufficient massage strength and effect, while avoiding excessive pressure on the muscles or deviation from the target position, in order to solve the above problems.

[0005] An embodiment of this application provides a massager, comprising:

[0006] The first body includes a support portion and a first connecting portion protruding from the support portion;

[0007] The second body includes a second connecting part and a massage part disposed on the second connecting part. The second connecting part is rotatably connected to the first connecting part, and the second connecting part is provided with a sliding groove along its thickness direction.

[0008] The flipping assembly includes a motor and an eccentric component. The motor is located inside the bearing portion, and one end of the eccentric component is located on the output shaft of the motor, while the other end extends into the sliding groove.

[0009] The second connecting part has a first stop surface and a second stop surface at the opening of the sliding groove to stop the eccentric member, and the included angle between the first stop surface and the second stop surface is 25°-35°.

[0010] In at least one embodiment of this application, the first connecting portion includes two pieces, which are located at one end of the support portion near the second body and are symmetrically arranged on both sides of the support portion.

[0011] The second connecting portion includes a rotating member located between the two sheet bodies;

[0012] The massager also includes a rotating shaft that passes through the two plates and the rotating component, and the second connecting part is rotatably connected to the first connecting part through the rotating shaft.

[0013] In at least one embodiment of this application, a frustum is provided at the end of the sheet body away from the bearing portion, and a circular groove corresponding to the frustum is provided on the rotating member. When the first connecting portion and the second connecting portion are rotatably connected, the frustum is located in the circular groove, and the centers of the frustum and the circular groove are both located on the axis of the rotating shaft.

[0014] In at least one embodiment of this application, the eccentric element includes:

[0015] An eccentric wheel is connected to the motor for transmission, and the motor drives the eccentric wheel to rotate around the rotation axis of the eccentric wheel;

[0016] An eccentric shaft is provided on the end of the eccentric wheel away from the motor, and the eccentric shaft extends into the sliding groove;

[0017] When the eccentric shaft moves, the eccentric shaft pries the second body to rotate around the rotating shaft until the side of the eccentric shaft is in contact with the first stop surface or the second stop surface.

[0018] In at least one embodiment of this application, the sliding groove includes a third surface located between the first stop surface and the second stop surface, the third surface being spaced apart from the eccentric shaft.

[0019] In at least one embodiment of this application, a speed control knob is provided at the end of the first body away from the second body, and the speed control knob is used to adjust the speed of the motor.

[0020] In at least one embodiment of this application, the speed change knob is provided with anti-slip texture.

[0021] In at least one embodiment of this application, the massager further includes a protective cover, which is fitted onto the first body, and the second body is located inside the protective cover, while the speed control knob is located outside the protective cover.

[0022] In at least one embodiment of this application, the protective sleeve is made of rubber.

[0023] In at least one embodiment of this application, a first rotating hole is provided on each of the two circular pedestals, and a second rotating hole is provided on the second connecting part. The two ends of the second rotating hole are respectively connected to the two first rotating holes, and the rotating shaft passes through the two first rotating holes and the second rotating hole.

[0024] The massager described above is designed with a first stop surface and a second stop surface located at the opening of the sliding groove, with an included angle of 25°-35°.

Detailed Implementation

[0039] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0040] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0041] An embodiment of this application provides a massager, comprising:

[0042] The first body includes a support portion and a first connecting portion protruding from the support portion;

[0043] The second body includes a second connecting part and a massage part disposed on the second connecting part. The second connecting part is rotatably disposed on the first connecting part, and the second connecting part is provided with a sliding groove along its thickness direction.

[0044] The flipping assembly includes a motor and an eccentric component. The motor is located inside the bearing portion, and one end of the eccentric component is located on the output shaft of the motor, while the other end extends into the sliding groove.

[0045] The second connecting part has a first stop surface and a second stop surface at the opening of the sliding groove to stop the eccentric member. The included angle between the first stop surface and the second stop surface is 25°-35°. The massager provided above is designed with the first stop surface and the second stop surface located at the opening of the sliding groove, with an included angle of 25°-35°. This design is crucial because it limits the range of movement of the eccentric member within the sliding groove, thereby controlling the rotation amplitude of the massage part. This ensures that the rotation amplitude of the massage part is at a moderate level, avoiding excessive pressure or insufficient force on the muscles during the massage process.

[0046] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] Please see Figures 1-12 An embodiment of this application provides a massager 100, comprising:

[0048] The first body 1 includes a support portion 11 and a first connecting portion 12 protruding from the support portion 11.

[0049] The second body 2 includes a second connecting part 22 and a massage part 21 disposed on the second connecting part 22. The second connecting part 22 is rotatably disposed on the first connecting part 12, and the second connecting part 22 is provided with a sliding groove 221 along its thickness direction.

[0050] The flipping assembly 3 includes a motor 32 and an eccentric member 31. The motor 32 is located inside the bearing part 11, and one end of the eccentric member 31 is located on the output shaft of the motor 32, while the other end extends into the sliding groove 221.

[0051] The second connecting part 22 has a first stop surface 225 and a second stop surface 226 of the stop eccentric member 31 at the opening of the sliding groove 221, and the included angle between the first stop surface 225 and the second stop surface 226 is 25°-35°.

[0052] Specifically, the support portion 11 serves as the main structure of the massager 100, supporting and fixing other components such as the motor 32 and the eccentric member 31. The first connecting portion 12 connects to the second body 2, enabling the massage portion 21 to rotate, providing a stable support and connection foundation, and ensuring the overall stability and durability of the massager 100. The second body 2 includes a second connecting portion 22 and a massage portion 21 disposed on the second connecting portion 22. The second connecting portion 22 is rotatably disposed on the first connecting portion 12, and a sliding groove 221 is formed along its thickness direction. The second connecting portion 22 connects to the first connecting portion 12, allowing the massage portion 21 to rotate around the first connecting portion 12. The massage portion 21 directly contacts the user to provide a massage effect. The sliding groove 221 provides space for the movement of the eccentric member 31, thereby enabling the massage portion 21 to flip, allowing it to simulate the complex movements of a human hand massage and improving the massage effect. The design of the sliding groove 221 increases the diversity and flexibility of massage movements. The flipping assembly 3 includes a motor 32 and an eccentric member 31. The motor 32 is located within the support portion 11, and one end of the eccentric member 31 is mounted on the output shaft of the motor 32, while the other end extends into the sliding groove 221. The motor 32 provides power to the massager 100, driving the eccentric member 31 to rotate. Driven by the motor 32, the eccentric member 31 moves within the sliding groove 221, thereby pushing the second connecting portion 22 (and the massage portion 21) to flip. This achieves the automatic flipping function of the massage portion 21, improving the efficiency and comfort of the massage. By adjusting the speed of the motor 32 and the shape of the eccentric member 31, the massage intensity and flipping amplitude can be flexibly controlled. The second connecting portion 22 has a first stop surface 225 and a second stop surface 226 at the opening of the sliding groove 221 to stop the eccentric member 31, with an included angle of 25°-35° between the first stop surface 225 and the second stop surface 226. The stop surface restricts the movement range of the eccentric component 31 within the sliding groove 221, thereby controlling the rotation amplitude of the massage unit 21. By adjusting the included angle, the rotation angle of the massage unit 21 can be flexibly controlled to meet the needs of different users. This improves the safety and controllability of the massager 100 and avoids damage caused by excessive rotation. The angle design makes the massage intensity more uniform, improving user comfort.

[0053] The specific operation process is as follows: when the user turns on the massager 100, the motor 32 starts working. The output shaft of the motor 32 then drives the eccentric member 31 to rotate. The eccentric member 31 moves within the sliding groove 221, pushing the second connecting part 22 (and the massage part 21) to flip. When the eccentric member 31 moves to the first stop surface 225 or the second stop surface 226, the massage part 21 reaches its maximum flip angle. During rotation, the eccentric member, due to the restriction of the sliding groove, pries the massage part to flip repeatedly within a suitable range, thereby achieving a massage effect. The length D of the massage part 21 in existing massagers 100 is generally between 50mm and 60mm; the massage part 21 in this application is mainly applicable to this range.

[0054] Furthermore, to demonstrate the optimal swing amplitude of the massage part 21 during massage, this plan designed an experiment. The experimental scheme is as follows: the experimental equipment consists of a prototype massager 100 (with an adjustable angle between the first stop surface 225 and the second stop surface 226), a force sensor (for measuring massage force), and a muscle relaxation detection instrument (for measuring the degree of relaxation of the back muscles after massage). Since the length D of the massage part 21 of the existing massager 100 is generally between 50mm and 60mm, the length D of the massage part 21 of the prototype massager 100 is set to 55mm. The experimental subjects are 30 volunteers aged 20-50 years who are healthy and have no obvious muscle diseases. The angle between the first stop surface 225 and the second stop surface 226 is set to five representative angles: 20°, 25°, 30°, 35°, and 40°. At each angle, the massage unit 21 was positioned at three different massage points: the starting position (when in contact with the first stop surface 225), the middle position (the midpoint of the angle), and the ending position (when in contact with the second stop surface 226). Each subject received a massage at each angle and at each massage point for 5 minutes each time. After each massage, a force sensor was used to measure the massage force, and a muscle relaxation level detector was used to measure the degree of muscle relaxation after the massage. The average massage force and the average muscle relaxation level at each angle and at each massage point were recorded.

[0057] Average Muscle Relaxation Level (%)

[0058]

[0059] Based on the experimental data above, at the midpoint of a 30° angle, the massage intensity is moderate (58N), and the muscle relaxation level is highest (70%). As the angle increases from 20° to 40°, both the massage intensity and muscle relaxation level show a trend of first increasing and then decreasing, reaching their optimal values ​​at the midpoint of a 30° angle. These data indicate that the massage effect is best when the angle between the first stop surface 225 and the second stop surface 226 is between 25° and 35° (especially 30°).

[0060] In one specific example, the first connecting part 12 includes two pieces 121, which are located at one end of the support part 11 near the second body 2 and are symmetrically arranged on both sides of the support part 11.

[0061] The second connecting part 22 includes a rotating member 222 located between the two pieces 121.

[0062] The massager 100 also includes a rotating shaft 4, which passes through the two plates 121 and the rotating member 222. The second connecting part 22 is rotatably connected to the first connecting part 12 via the rotating shaft 4.

[0063] Specifically, the two plates 121, as the main components of the first connecting part 12, provide a stable support structure for the rotation of the second connecting part 22. They are located at the end of the support part 11 near the second body 2, ensuring a reasonable and stable position for the rotational connection. The two symmetrically arranged plates 121 enhance the structural strength of the first connecting part 12, improving the overall stability and durability of the massager 100. The symmetrical arrangement of the two plates 121 on both sides of the support part 11 is not only aesthetically pleasing but, more importantly, ensures the balance of the rotational connection. This helps reduce vibration and noise generated during rotation, improving the user experience of the massager 100. A well-balanced rotational connection can extend the service life of the massager 100 while reducing user discomfort during use. The rotating component 222 is the core part of the second connecting part 22. It is located between the two plates 121 and is rotatably connected to the first connecting part 12 via the rotating shaft 4. This allows the second body 2 (including the massage part 21) to rotate relative to the first body 1. Through the arrangement of the rotating component 222, the massage part 21 can flexibly adjust its angle and position to adapt to the massage needs of different users. The rotating shaft 4 is a key component for achieving the rotatable connection between the first connecting part 12 and the second connecting part 22. It runs through both plates 121 and the rotating component 222, ensuring smooth and stable rotation. The introduction of the rotating shaft 4 makes the massager 100 more compact and rational in structure, while also improving the reliability and durability of rotation. When the user starts the massager 100, the motor 32 begins to work, driving the eccentric component 31 (such as the eccentric wheel 311) to rotate. One end of the eccentric component 31 is connected to the output shaft of the motor 32, and the other end extends into the sliding groove 221 of the second connecting part 22. As the eccentric component 31 rotates, its eccentric shaft 312 moves within the sliding groove 221, prying the second body 2 (including the rotating component 222 and the massage part 21) to rotate around the rotating shaft 4. Since the opening of the sliding groove 221 has a first stop surface 225 and a second stop surface 226, the eccentric shaft 312 will change its direction of movement under the action of these stop surfaces when it moves, thereby realizing the reciprocating rotation of the massage part 21.

[0064] In a specific example, a frustum 122 is provided at the end of the plate 121 away from the bearing part 11, and a circular groove 223 corresponding to the frustum 122 is provided on the rotating part 222. When the first connecting part 12 and the second connecting part 22 are rotatably connected, the centers of the frustum 122 and the circular groove 223 are both located on the axis of the rotating shaft 4.

[0065] Specifically, the frustum 122 is designed to precisely fit with the circular groove 223 on the rotating component 222. The frustum 122 typically has a smooth curved surface and precise dimensions to ensure a tight fit and smooth rotation with the circular groove 223. The design of the frustum 122 enhances the connection stability between the first connecting part 12 and the second connecting part 22, reducing potential gaps and wobbling during rotation, thereby improving the overall stability and durability of the massager 100. The circular groove 223 is a key structure on the rotating component 222, used to accommodate the frustum 122 on the plate 121. The size and shape of the circular groove 223 match the frustum 122 to ensure a tight fit between them. The design of the circular groove 223 makes the first connecting part 12 and the second connecting part 22 more stable during rotational connection, reducing friction and wear caused by improper fit, and extending the service life of the massager 100. When the first connecting part 12 and the second connecting part 22 are rotatably connected via the rotating shaft 4, the frustum 122 is precisely embedded in the circular groove 223, and the rotating shaft 4 passes through the center of both the frustum 122 and the circular groove 223. This design ensures the stability and smoothness of the rotatable connection. Through the tight fit between the frustum 122 and the circular groove 223 and the passage of the rotating shaft 4, precise rotation between the first connecting part 12 and the second connecting part 22 can be achieved. This design not only improves the structural compactness of the massager 100 but also makes the rotation process smoother and more reliable.

[0066] In a specific example, the eccentric component 31 includes:

[0067] Eccentric wheel 311 is connected to motor 32 for transmission, and motor 32 drives eccentric wheel 311 to rotate around the rotation axis of eccentric wheel 311;

[0068] An eccentric shaft 312 is provided on the end of the eccentric wheel 311 that is away from the motor 32, and the eccentric shaft 312 extends into the sliding groove 221;

[0069] When the eccentric shaft 312 moves, the eccentric shaft 312 pries the second body 2 to rotate around the rotating shaft 4 until the side of the eccentric shaft 312 is in contact with the first stop surface 225 or the second stop surface 226.

[0070] Specifically, eccentric component 31 is the name of an integral assembly comprising multiple parts that work together to achieve a specific function. Eccentric wheel 311 is one of the main parts of eccentric component 31. It typically has an asymmetrical axis, namely eccentric shaft 312, which allows it to produce a specific motion effect during rotation. Eccentric wheel 311 is connected to motor 32 via a transmission mechanism (such as gears, belts, etc.) so that motor 32 can drive it to rotate. Motor 32 is the power-providing component; it generates power through rotation and transmits it to eccentric wheel 311 through the transmission mechanism. Driven by motor 32, eccentric wheel 311 rotates around its own axis of rotation (that is, the axis of symmetry of eccentric wheel 311, but not necessarily eccentric shaft 312). Eccentric shaft 312 is a key part of eccentric wheel 311; it is located at the end of eccentric wheel 311 opposite to motor 32 and is eccentric relative to the axis of rotation of eccentric wheel 311. A portion of the eccentric shaft 312 extends into a sliding groove 221 (which may be part of the second body 2 or other components) so that the eccentric shaft 312 can move within the sliding groove 221 or pry other components when the eccentric wheel 311 rotates. When the eccentric wheel 311 rotates under the drive of the motor 32, the eccentric shaft 312 also moves accordingly. Because the eccentric shaft 312 is eccentric and extends into the sliding groove 221, it moves within the sliding groove 221 during the rotation of the eccentric wheel 311, generating a certain prying action. This prying action causes the second body 2 (which may be a movable part of the massager 100) to rotate around its axis 4. During rotation, the second body 2 is subject to certain restrictions (such as stop surfaces). When it rotates to a certain position, the axial side of the eccentric shaft 312 will engage with these stop surfaces, thereby limiting further rotation of the second body 2.

[0071] In one specific example, the sliding groove 221 includes a third surface 2211 located between the first stop surface 225 and the second stop surface 226.

[0072] Specifically, the first stop surface 225 and the second stop surface 226 are located at the two ends of the sliding groove 221, and the included angle between them (usually 25°-35°) provides restriction and guidance for the movement of the eccentric shaft 312. The third surface 2211 is located between the first stop surface 225 and the second stop surface 226, forming a relatively flat surface or a surface with a specific curvature. This surface does not directly contact the eccentric shaft 312 during movement, but maintains a certain distance. The existence of the distance provides a certain amount of movement space for the eccentric shaft 312, preventing the eccentric shaft 312 from getting stuck in the sliding groove.

[0073] In one specific example, the end of the first body 1 away from the second body 2 is provided with a speed change knob 5, which is used to adjust the speed of the motor 32.

[0074] Specifically, this feature introduces a key adjustment mechanism into the massager 100—the speed control knob 5. This knob is located at the distal end of the first body 1, i.e., the end furthest from the second body 2 (containing the massage section 21), for easy user operation. The main function of the speed control knob 5 is to adjust the rotational speed of the motor 32, thereby controlling the massage intensity and frequency of the massager 100. The speed control knob 5 is typically connected to the motor 32 mechanically or electronically. In a mechanical connection, the knob may directly act on a speed control mechanism of the motor 32, such as changing the power input voltage or current of the motor 32, or adjusting the rotational speed of the motor 32 via gears, belts, or other transmission devices. In an electronic connection, the knob may be a potentiometer or encoder, whose output signal is converted into a command recognizable by the motor 32 controller, thereby adjusting the rotational speed of the motor 32. When the user rotates the speed control knob 5, this action triggers the aforementioned connection mechanism, causing a change in the rotational speed of the motor 32. The direction of rotation (clockwise or counterclockwise) and the amount of rotation (angle or number of rotations) of the knob determine whether the speed of motor 32 increases or decreases.

[0075] In one specific example, the speed change knob 5 is provided with anti-slip texture 51.

[0076] Specifically, in the design of the massager 100, the speed control knob 5 is a key operating component used to adjust the rotation speed of the motor 32, thereby controlling the intensity and frequency of the massage. To ensure that users can operate this knob stably and accurately, especially when their hands are wet or sweaty, the designer added an anti-slip texture 51 to the knob surface. The anti-slip texture 51 is typically composed of a series of tiny bumps or grooves, which can be straight, wavy, spiral, etc. Different shapes can provide different levels of friction and feel to suit different users' habits. The anti-slip texture 51 is usually machined together with the main body material of the knob to ensure a firm connection between them. Common materials include plastic, rubber, or metal, and the choice of these materials depends on the overall design style of the massager 100, the cost budget, and the user's usage environment. The distribution density of the anti-slip texture 51 is also an important design parameter. Too dense a texture may result in an overly rough feel, while too sparse a texture may not provide sufficient friction. Therefore, the designer needs to reasonably determine the distribution density of the anti-slip texture 51 based on the size and shape of the knob and the user's usage habits. When the user's hand contacts the speed control knob 5, the anti-slip texture 51 increases the friction between the hand and the knob surface, thus preventing the knob from slipping or turning too fast during operation. This design allows the user to hold the knob more stably and accurately adjust the speed of the motor 32.

[0077] In one specific example, the massager 100 also includes a protective cover 6, which is fitted onto the first body 1, and the second body 2 is located inside the protective cover 6, while the speed control knob 5 is located outside the protective cover 6.

[0078] Specifically, the massager 100 also includes a protective cover 6, indicating that in addition to the main components such as the first body 1, the second body 2, and the speed control knob 5, the massager 100 is also equipped with a protective cover 6. The protective cover 6 is an auxiliary component of the massager 100, providing additional protection and safety. The protective cover 6 is fitted over the first body 1, meaning it is worn outside the first body 1. The protective cover 6 typically has sufficient elasticity and strength to fit snugly against the first body 1, thus preventing direct impact or damage from external objects. The second body 2 is located inside the protective cover 6, indicating that the second body 2 is contained within the protective cover 6. Since the protective cover 6 is fitted over the first body 1, and the second body 2 is usually connected to or adjacent to the first body 1, the second body 2 is naturally covered by the protective cover 6. This design helps protect the second body 2 from interference or damage from the external environment. The speed control knob 5 is located outside the protective cover 6, meaning it is exposed outside the protective cover 6. The speed control knob 5 is a crucial operating component used to adjust the rotational speed of the motor 32, thereby controlling the intensity and frequency of the massage. Therefore, it needs to be able to protrude from the protective cover 6 for free user operation. If the speed control knob 5 were covered by the protective cover 6, it would not function effectively. Therefore, designing the speed control knob 5 outside the protective cover 6 is reasonable. Through this design, the protective cover 6 provides effective protection for the main components of the massager 100 (especially the first body 1 and the second body 2). It prevents direct impact or damage to the massager 100 from external objects, while also reducing noise and vibration generated during use.

[0079] In one specific example, the protective sleeve 6 is made of rubber.

[0080] Specifically, the protective cover 6 is an important component of the massager 100, typically used to wrap or cover other parts of the massager 100 to provide additional protection and safety. The protective cover 6 is made of rubber. Rubber is a widely used material, favored for its many excellent properties. Rubber has good elasticity, allowing it to fit snugly against other parts of the massager 100 while adapting to parts of different shapes and sizes. Rubber has high abrasion resistance, resisting friction and wear from external objects, thus extending the lifespan of the protective cover 6. The rubber surface typically has a certain degree of roughness, increasing friction with hands or other objects and preventing the massager 100 from slipping or sliding during use. Rubber also has a certain sound insulation and shock absorption effect, reducing noise and vibration generated by the massager 100 during use, improving comfort and safety.

[0081] In a specific example, each of the two frustums 122 is provided with a first rotating hole 123, and the second connecting part 22 is provided with a second rotating hole 224. The two ends of the second rotating hole 224 are respectively connected to the two first rotating holes 123, and the rotating shaft 4 passes through the two first rotating holes 123 and the second rotating hole 224.

[0082] Specifically, both frustums 122 have first rotating holes 123, indicating the existence of two frustum-shaped structures, each with one or more first rotating holes 123. These first rotating holes 123 are typically used to allow some form of rotational motion, such as the rotation of a shaft or rod. The second connecting portion 22 has second rotating holes 224, indicating that in addition to the two frustums 122, there is another structure called the second connecting portion 22. This second connecting portion 22 also has one or more second rotating holes 224. These second rotating holes 224 are likely functionally similar to the first rotating holes 123, both allowing rotational motion. The two ends of the second rotating holes 224 are connected to the two first rotating holes 123 respectively, indicating that the second rotating holes 224 are not isolated, but spatially connected to the first rotating holes 123 on the two frustums 122. This connectivity allows a shaft or rod to pass through all three holes simultaneously, thereby enabling relative rotation between the two frustums 122 and the second connecting portion 22. The rotating shaft 4 passes through the two first rotating holes 123 and the second rotating hole 224, indicating the existence of a rotating shaft 4 that passes through the first rotating holes 123 on the two frustums 122 and the second rotating hole 224 on the second connecting part 22. This rotating shaft 4 is a key component for realizing rotational motion, allowing the two frustums 122 to rotate relative to the second connecting part 22. Through this design, the two frustums 122 can rotate relative to the second connecting part 22 via the rotating shaft 4. This rotational motion may be used to achieve a specific mechanical function, such as adjusting angles, transmitting torque, or changing the direction of motion.

[0083] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
