After continuous research, design, and repeated trial production of samples and improvement, the present invention with practical value is finally created.

[0063] Please refer to Figure 1-3 , an embodiment of the present invention provides an automatic lifting knob device. The overall structure of this device is compact and ingeniously designed, mainly consisting of several key parts: a knob assembly 1, a guiding bracket 2, an automatic lifting assembly 3, and a base 4.

[0064] Specifically, the knob assembly 1 is disposed on one end face of the guiding bracket 2. This design enables a stable connection relationship between the knob assembly 1 and the guiding bracket 2, laying a foundation for subsequent coordinated movement.

[0065] The automatic lifting assembly 3 is disposed on the other opposite end face of the guiding bracket 2 and is located between the guiding bracket 2 and the base 4. This layout makes full use of the space between the guiding bracket 2 and the base 4, enabling the automatic lifting assembly 3 to play its due driving role.

[0066] The automatic lifting assembly 3 plays a core driving role in the entire device. It has the required driving force to drive the guiding bracket 2 to move up and down relative to the base 4. Since the knob assembly 1 is tightly connected to the guiding bracket 2, when the guiding bracket 2 moves up and down under the action of the automatic lifting assembly 3, the knob assembly 1 will also move up and down synchronously. Through this coordinated movement mechanism, the knob assembly 1 can flexibly and smoothly switch between the extended state and the retracted state.

[0067] It can be understood that the automatic lifting knob device proposed in the embodiment of the present invention drives the guiding bracket 2 to move up and down relative to the base 4 through the automatic lifting assembly 3, and then drives the knob assembly 1 to flexibly switch between the extended state and the retracted state. This design concept has significant advantages. In practical applications, this design can fully consider the specific needs of users and diverse usage scenarios, and dynamically adjust the position of the knob assembly 1.

[0068] For example, when a user needs to operate the device, the knob assembly 1 can automatically extend to a suitable position, facilitating the user to quickly and accurately adjust various parameters of the device, greatly improving the operation efficiency and convenience. When there is no need to operate or the device is in an idle state, the knob assembly 1 can automatically retract. This function not only effectively avoids misoperations caused by accidental touches, ensuring the safety and stability of the device, but also saves the occupied space of the device, making the appearance of the device more concise and beautiful, and enhancing the overall quality sense of the device.

[0069] This automatic lifting knob device with dynamic adjustment function not only successfully solves the inconveniences existing in the use of traditional fixed knobs, such as the inability to flexibly adjust the position according to the usage scenario, but also overcomes the defect that traditional knobs affect the aesthetics of the device. More importantly, it provides greater freedom and flexibility for the overall design of the device, enabling the device to better adapt to various complex and changeable usage scenarios and the personalized needs of different users, significantly enhancing the practicality and aesthetics of the device, and having broad market application prospects and important practical value.

[0070] Please refer to Figure 4-6 , in an implementation manner of this embodiment, the automatic lifting assembly 3 serves as the core power and transmission module for the automatic lifting knob device to achieve dynamic adjustment of the position of the knob assembly 1. Its structural design is delicate and its functions are complete. It is mainly composed of three key components: a driving motor 301, a transmission mechanism 302, and a lifting screw 303.

[0071] Specifically, the driving motor 301 is stably installed on the guiding bracket 2. As the power source, the stability of the performance and the accuracy of the output of the driving motor 301 play a crucial role in the normal operation of the entire automatic lifting assembly 3. A close transmission connection relationship is established between the output shaft of the driving motor 301 and the transmission mechanism 302. The transmission mechanism 302 acts as a key role in power transmission and conversion here. It can transmit the rotational power of the output shaft of the driving motor 301 to the subsequent components in a suitable manner, and may also adjust the power to a certain extent according to actual needs, such as changing parameters such as rotational speed and torque, to ensure the smoothness and efficiency of the entire transmission process.

[0072] The lifting screw 303 is connected to the base 4 by means of a threaded fit. This threaded fit method has advantages such as good self-locking property and high transmission accuracy, and can ensure the stability and accuracy of the guiding bracket 2 during the lifting process. Through this threaded fit, the lifting screw 303 can generate an axial displacement when rotating, thereby driving the connected components to perform lifting motion.

[0073] When the driving motor 301 starts, its output shaft begins to rotate, and transmits the rotational power to the lifting screw 303 through the transmission mechanism 302. Under the action of the transmission mechanism 302, the lifting screw 303 starts to rotate accordingly. Since there is a threaded engagement relationship between the lifting screw 303 and the base 4, when the lifting screw 303 rotates, it will generate a displacement along its axial direction, so that the guiding bracket 2 can move up and down relative to the base 4 along with the axial displacement of the lifting screw 303. Through this ingenious mechanical transmission structure, the precise lifting of the guiding bracket 2 is realized, and then the knob assembly 1 is flexibly switched between the extended state and the retracted state, meeting the requirements for the position of the knob assembly 1 in different usage scenarios, and improving the flexibility of the device and the user experience.

[0074] Please refer to again Figure 4-5 , in an implementation manner of this embodiment, the base 4 is a key component that plays a supporting and positioning role in the entire automatic lifting knob device, and its structural design plays an important role in the stable operation and function realization of the device. On the base 4, an internal thread 5 that is in threaded engagement with the lifting screw 303 is carefully provided.

[0075] The provision of this internal thread 5 is not arbitrary, but is based on rigorous design considerations. Its specification parameters, such as pitch, tooth profile, etc., are all matched with the external thread of the lifting screw 303 to ensure that the two can achieve a tight and precise threaded engagement. This threaded engagement method has many advantages. On the one hand, it can provide reliable connection and support, so that the lifting screw 303 can move stably along the predetermined axial direction during rotation, thereby driving the guiding bracket 2 to move up and down; on the other hand, the threaded engagement also has a certain self-locking performance, which can keep the current positions of the guiding bracket 2 and the knob assembly 1 after the driving motor 301 stops working, preventing accidental movement due to external forces, and ensuring the stability and safety of the device.

[0076] During the actual working process, when the driving motor 301 starts and drives the lifting screw 303 to rotate, the external thread on the lifting screw 303 meshes with the internal thread 5 on the base 4, generating an axial thrust or pull, so that the lifting screw 303 rises or falls along its axial direction while rotating, and the guiding bracket 2 will perform synchronous lifting and lowering movements, and then drive the knob assembly 1 to be flexibly switched between the extended state and the retracted state.

[0077] In an implementation manner of this embodiment, the length of the internal thread 5 is set to be not less than the stroke of the lifting and lowering movement of the guiding bracket 2.

[0078] This setting is not arbitrary, but the result of a comprehensive trade-off considering various factors such as the overall functional requirements of the device, structural stability, and operational reliability. From the perspective of function realization, the lifting motion stroke of the guiding bracket 2 is the key factor determining the extending and retracting range of the knob assembly 1. The length of the internal thread 5 must be able to fully meet this stroke requirement to ensure that the guiding bracket 2 maintains a stable and effective thread engagement with the lifting screw 303 during the lifting process. If the length of the internal thread 5 is too short, when the guiding bracket 2 moves to the end of the stroke, the thread engagement may fail, resulting in the inability of the guiding bracket 2 to continue lifting stably, thereby affecting the normal extension and retraction of the knob assembly 1 and reducing the overall performance of the device.

[0079] From the perspective of structural stability, an internal thread 5 of sufficient length can provide more sufficient support and guidance for the lifting screw 303. During the lifting motion of the guiding bracket 2, the lifting screw 303 is subjected to various forces and torques from the guiding bracket 2. Through the close engagement with the lifting screw 303, the internal thread 5 can effectively disperse and bear these forces and torques, reducing the bending deformation and vibration of the lifting screw 303 and ensuring the structural stability of the device.

[0080] From the perspective of operational reliability, an internal thread 5 with a length not less than the lifting motion stroke of the guiding bracket 2 can reduce the risk of device failure caused by problems such as thread wear and loosening. During long-term use, a certain degree of wear will inevitably occur at the thread engagement part. The sufficiently long internal thread 5 can provide a certain wear allowance, ensuring an effective engagement between the lifting screw 303 and the internal thread 5 even in the case of a certain degree of wear, and ensuring the stable and reliable operation of the device for a long time.

[0081] Therefore, setting the length of the internal thread 5 to be not less than the lifting motion stroke of the guiding bracket 2 is an important technical measure to ensure the normal, stable, and reliable operation of the automatic lifting knob device.

[0082] Please refer to Figure 4-5 again, and in combination with reference to Figure 7 , in an implementation manner of this embodiment, the base 4 is provided with a guiding groove 6;

[0083] The opening of this guiding groove 6 is based on the consideration of precise control of the motion trajectory of the guiding bracket 2. Its shape, size, and layout position on the base 4 have all undergone rigorous engineering design and mechanical analysis. The cross-sectional shape of the guiding groove 6 is adapted to the shape of the inserted part of the guiding bracket 2 to ensure a tight and stable engagement relationship between the two, while minimizing friction and wear during the motion process.

[0084] The guiding bracket 2 is precisely inserted into the guiding groove 6. This plug-in structural design establishes a clear relative position relationship between the guiding bracket 2 and the base 4, providing a reliable positioning basis for subsequent lifting movements. Moreover, the guiding bracket 2 can perform smooth and precise lifting movements relative to the base 4 along the guiding groove 6 under the constraint and guidance of the guiding groove 6.

[0085] The existence of the guiding groove 6 has multiple important significances. From the aspect of motion accuracy, it can effectively restrict the motion direction of the guiding bracket 2 during the lifting process, prevent unstable phenomena such as deviation and shaking, ensure that the guiding bracket 2 always lifts along the predetermined axial direction, so as to ensure that the knob assembly 1 can accurately reach the required position and meet the precise requirements for the knob position in different usage scenarios.

[0086] In terms of structural stability, the guiding groove 6 provides additional support and constraint for the guiding bracket 2, enhancing the structural strength of the entire device. During the lifting movement of the guiding bracket 2, it can withstand various forces and torques from the guiding bracket 2, disperse stress concentration, reduce deformation and damage of the device caused by uneven stress, and improve the reliability and service life of the device.

[0087] From the perspective of assembly and maintenance, the design of the guiding groove 6 makes the installation and disassembly of the guiding bracket 2 more convenient. During the assembly process, the guiding bracket 2 can be accurately inserted into the guiding groove 6 to complete the preliminary positioning, reducing the assembly difficulty and cost. During the maintenance process, if it is necessary to inspect, repair or replace the guiding bracket 2 or related components, it is also convenient for the operator to perform operations quickly and accurately.

[0088] In summary, the guiding groove 6 opened on the base 4 and the matching design between the guiding bracket 2 and the guiding groove 6 are important structural features to ensure the stable, precise and reliable operation of the automatic lifting knob device.

[0089] Please refer to again Figure 3-5 , in an implementation manner of this embodiment, to further optimize the structural layout and operation stability of the automatic lifting knob device, the automatic lifting knob device also particularly adds a key component, the fixed seat 7.

[0090] The fixed seat 7 plays an important role in connection and support in the entire device. Its design fully considers the adaptability and stability requirements between the automatic lifting component 3 and the guiding bracket 2. Structurally, the fixed seat 7 has a specific shape and size, and the material selection has also been strictly considered to ensure that it can withstand various forces and torques generated during the operation of the automatic lifting component 3, and at the same time has good wear resistance and corrosion resistance, extending the service life of the device.

[0091] The automatic lifting assembly 3 is stably arranged on the guiding bracket 2 through the fixed seat 7. This arrangement is not a simple physical connection, but a carefully designed mechanical assembly structure. During the assembly process, a specific connection method (such as bolt connection, welding, etc., and the specific connection method can be determined according to the actual design requirements and process requirements) is used between the fixed seat 7 and the guiding bracket 2 to achieve a tight combination, ensuring sufficient connection strength and stiffness between the two. At the same time, a reliable connection and positioning method is also adopted between the automatic lifting assembly 3 and the fixed seat 7, so that the automatic lifting assembly 3 can be accurately installed on the fixed seat 7 and maintain a stable relative position during operation.

[0092] Arranging the automatic lifting assembly 3 on the guiding bracket 2 through the fixed seat 7 has many important advantages. First of all, this arrangement can effectively transfer the driving force and movement generated by the automatic lifting assembly 3 to the guiding bracket 2, ensuring that the guiding bracket 2 can perform lifting movements in the expected manner, and then driving the knob assembly 1 to achieve the functions of extending and retracting. Secondly, the presence of the fixed seat 7 provides a stable installation platform for the automatic lifting assembly 3, reducing the vibration and shaking of the automatic lifting assembly 3 during operation, and improving the operation accuracy and reliability of the device. In addition, this structural design also facilitates the assembly, debugging and maintenance of the device. During the assembly process, the operator can easily install the automatic lifting assembly 3 on the fixed seat 7 and then connect the fixed seat 7 to the guiding bracket 2, reducing the assembly difficulty and cost. During the debugging and maintenance process, it is also convenient to check, repair and replace the automatic lifting assembly 3, improving the maintainability of the device.

[0093] In summary, in this implementation manner of this embodiment, the added fixed seat 7 and the design of arranging the automatic lifting assembly 3 on the guiding bracket 2 through the fixed seat 7 are of great significance for improving the overall performance and stability of the automatic lifting knob device.

[0094] Please refer to again Figure 3-5 and in combination with reference to Figure 8-10 In an implementation manner of this embodiment, in order to further enhance the intelligent level and operation accuracy of the automatic lifting knob device, the automatic lifting knob device also innovatively adds a lifting control component 8.

[0095] As the core module for achieving precise position control in the entire device, the lifting control component 8 integrates advanced sensor technology, signal processing technology and control algorithms, and has high sensitivity and reliability, and can obtain the lifting position information of the guiding bracket 2 in real time and accurately. At the same time, the lifting control component 8 is also equipped with corresponding signal processing circuits and microcontrollers for processing, analyzing and judging the signals collected by the sensors, and outputting corresponding control instructions according to the preset control strategies.

[0096] The core function of the lifting control component 8 is to monitor the lifting position of the guiding bracket 2. During the lifting movement of the guiding bracket 2, the lifting control component 8 continuously tracks the real-time position of the guiding bracket 2 through its built-in sensor, and compares the collected position data with the pre-set safe position range in real time. Once it detects that the lifting position of the guiding bracket 2 approaches or reaches the preset limit position (i.e., the critical point where it may rise or fall excessively), the lifting control component 8 will immediately respond.

[0097] Specifically, when the guiding bracket 2 rises close to the upper limit position, the lifting control component 8 will quickly issue a control signal to cut off the power supply of the driving motor 301 or change its rotation direction, preventing the guiding bracket 2 from continuing to rise, so as to avoid damage to other components of the device or exceeding the design allowable working range due to excessive rising. Similarly, when the guiding bracket 2 descends close to the lower limit position, the lifting control component 8 will also take control measures in a timely manner to prevent the guiding bracket 2 from descending excessively, ensuring the safe operation of the device.

[0098] By precisely controlling the lifting position of the guiding bracket 2, the lifting control component 8 effectively avoids a series of problems caused by the movement of the guiding bracket 2 exceeding the reasonable range. For example, it can prevent the knob component 1 from colliding with other components of the device during the extension or retraction process, reducing the probability of mechanical wear and failure; at the same time, it also ensures that the knob component 1 can accurately reach the operation position required by the user when in the extended state and can accurately reach the required position when in the retracted state, without affecting the overall appearance and space occupation of the device.

[0099] In summary, in this implementation manner of this embodiment, the added lifting control component 8 and its monitoring and control functions for the lifting position of the guiding bracket 2 play a crucial role in improving the overall performance, safety and user experience of the automatic lifting knob device.

[0100] Please refer to Figure 4-5 again. In one implementation manner of this embodiment, in order to achieve precise monitoring and control of the lifting position of the guiding bracket 2 in the automatic lifting knob device, the lifting control component 8 may preferably adopt a precise design based on the Hall effect, and its specific composition includes a PCB board 801, two Hall chips 802 and a magnet 803.

[0101] The PCB board 801 serves as the circuit carrier and control core of the entire lifting control component 8 and is firmly disposed on the guiding bracket 2. It not only provides a reliable electrical connection platform for the Hall chip 802, but also integrates necessary signal processing circuits and control logics, capable of quickly and accurately processing the signals collected by the Hall chip 802 and generating corresponding control instructions according to the processing results. The design of the PCB board 801 fully considers factors such as electromagnetic compatibility, heat dissipation performance, and anti-interference ability to ensure stable and reliable operation in a complex working environment.

[0102] The two Hall chips 802 are carefully disposed on the PCB board 801 and achieve reliable electrical connection with the PCB board 801. The two Hall chips 802 are arranged in an up-and-down layout in the lifting movement direction of the guiding bracket 2. This layout is obtained through precise calculation and experimental verification and can ensure that during the lifting process of the guiding bracket 2, the magnetic fields of the magnet 803 can be accurately detected at different positions. The Hall chip 802 is a magnetic sensor based on the Hall effect, which can convert the intensity and direction of the magnetic field into electrical signals for output. In this embodiment, the Hall chips 802 at different positions determine the lifting position of the guiding bracket 2 by detecting the magnetic field generated by the magnet 803 in real time, and then determine whether the guiding bracket reaches the highest position corresponding to the extended state or the lowest position corresponding to the retracted state.

[0103] The magnet 803 is disposed on the base 4, with its position fixed and corresponding to the lifting movement path of the guiding bracket 2. The main function of the magnet 803 is to generate a stable magnetic field, which will be detected by the Hall chip 802 during the lifting process of the guiding bracket 2. Parameters such as the magnetic field intensity, shape, and installation position of the magnet 803 are carefully designed and optimized to ensure good matching with the Hall chip 802, thereby ensuring the accuracy and reliability of detection. During the lifting process of the guiding bracket 2, the relative movement between the magnet 803 and the Hall chip 802 causes the Hall chip 802 that can detect the magnetic field of the magnet 803 to change. When the Hall chips 802 at different positions detect the magnetic field of the magnet 802, they convert the magnetic field change into an electrical signal and transmit it to the PCB board 801.

[0104] It can be understood that when the guiding bracket 2 rises, the upper Hall chip 802 gradually approaches the magnet 803, and the magnetic field intensity detected by it gradually increases. When the upper Hall chip 802 finally corresponds to the magnet 803, the detected magnetic field intensity reaches a preset threshold. At this time, the Hall chip 802 transmits the corresponding electrical signal to the PCB board 801, notifying the PCB board 801 to stop the automatic lifting component 3 from rising further, ensuring that the guiding bracket 2 stops at the highest position. At this time, the knob component 1 is in the extended state, asFigure 4 , Figure 8 and Figure 9 As shown. Similarly, when the guiding bracket 2 descends, the lower Hall chip 802 gradually approaches the magnet 803, and the detected magnetic field strength gradually increases. When the lower Hall chip 802 finally corresponds to the magnet 803, the detected magnetic field strength reaches a preset threshold, and the Hall chip 802 transmits an electrical signal to the PCB board 801, notifying the PCB board 801 to stop the automatic lifting assembly 3 from descending further, so that the guiding bracket 2 stops at the lowest position. At this time, the knob assembly 1 is in a retracted state, as Figure 5 and Figure 10 shown.

[0105] The PCB board 801 plays a crucial role in the entire lifting control process. On the one hand, after receiving an external instruction, it can send a start signal to the automatic lifting assembly 3 through the control circuit, thereby realizing the control of the lifting movement of the guiding bracket 2. On the other hand, when the PCB board 801 receives the electrical signal transmitted by the Hall chip 802, it can quickly analyze and process these signals, and send a stop signal to the automatic lifting assembly 3 according to the preset control logic to achieve precise control of the lifting position of the guiding bracket 2. Through this closed-loop control system based on the Hall effect, the lifting control assembly 8 can ensure that the guiding bracket 2 accurately reaches the predetermined position during the lifting process, improving the operation accuracy and reliability of the automatic lifting knob device.

[0106] In summary, the structural design of the lifting control assembly 8 in this embodiment realizes precise monitoring and control of the lifting position of the guiding bracket 2 through the coordinated work of the PCB board 801, two Hall chips 802, and the magnet 803, providing a strong guarantee for the stable and reliable operation of the automatic lifting knob device.

[0107] It can be understood that from the perspective of technical implementation and functional logic, it can be clearly recognized that the source of the instructions received by the PCB board 801 does not constitute a critical limiting factor. Specifically, the sources of these instructions are diverse and flexible, not limited to a specific device or apparatus. Among them, the knob assembly 1 is a common and intuitive human-machine interaction component. By rotating, pressing, etc. the knob, the user can generate corresponding control signals, which are then converted into instructions recognizable by the PCB board 801. However, this is not the only way for the instruction source.

[0108] In addition to the knob assembly 1, other remote control devices can also serve as the source for sending instructions. These remote control devices may employ wired or wireless communication technologies, such as Bluetooth, Wi-Fi, infrared, etc., to transmit the operation instructions input by the user through the remote control interface to the PCB board 801 in the form of electrical signals. The forms of the remote control devices are also diverse. It may be a dedicated remote control specifically designed for this automatic lifting knob device, or it may be an application integrated on intelligent terminals such as smartphones and tablets. By operating the interfaces of these applications, users can achieve remote control of the PCB board 801.

[0109] Regardless of whether the instructions originate from the knob or other remote control devices, the core responsibility of the PCB board 801 is to accurately receive, parse, and execute these instructions. It has powerful signal processing capabilities and logical judgment functions, and can perform a unified processing process on instructions from different sources to ensure that the device can achieve corresponding functions according to the user's intention, such as controlling the lifting of the guiding bracket 2 and adjusting the state of the knob assembly 1. This open and compatible design for the instruction source not only improves the usability and flexibility of the automatic lifting knob device but also provides strong support for its wide application in different scenarios.

[0110] In one implementation manner of this embodiment, the knob assembly 1, as a key operation component for the user to interact with the automatic lifting knob device, has established a close and reliable electrical connection relationship with the PCB board 801. This electrical connection is achieved through specific circuit traces, connectors, or conductive contacts and other structures to ensure the stability and accuracy of signal transmission.

[0111] When the user operates the knob assembly 1, such as rotating or pressing, elements such as sensors or switches inside the knob assembly 1 will sense these operations and convert them into corresponding electrical signals, that is, operation data. This operation data contains specific information about the user's operations, such as the rotation angle, speed, and pressing force, which is a direct manifestation of the user's operation intention.

[0112] The knob assembly 1 will promptly and accurately send this operation data to the PCB board 801 which is electrically connected to it. The PCB board 801, as the electronic control core of the entire device, integrates a variety of electronic components and circuits and has powerful data processing, analysis, and execution capabilities.

[0113] After receiving the operation data sent by the knob assembly 1, the PCB board 801 will start its built-in data processing program. First, the operation data is preprocessed to remove possible noise and interference signals, ensuring the accuracy and reliability of the data. Then, the processed data is deeply analyzed using preset algorithms and logic to interpret the user's operation intention. For example, the size of the parameter that the user hopes to adjust is judged according to the rotation angle and speed, and whether the user triggers a specific function is judged according to the pressing force.

[0114] Finally, the PCB board 801 will perform corresponding operations according to the analysis results. These operations may include controlling the start, stop, forward and reverse rotation, and speed adjustment of the drive motor 301 to achieve the lifting movement of the guide bracket 2; or adjusting other functional parameters of the device, such as volume size, brightness level, etc.; it may also trigger specific application programs or functional modules to provide a more rich and personalized user experience.

[0115] Through the electrical connection between the knob assembly 1 and the PCB board 801, as well as the processing, analysis, and execution of the operation data by the PCB board 801, the precise mapping and efficient interaction between the user operation and the device function are realized, effectively improving the intelligent level and user experience of the automatic lifting knob device.

[0116] Please refer to again Figure 1 and 7 , in an implementation manner of this embodiment, the base 4, as an important support and installation base component of the automatic lifting knob device, its structural design fully considers the installation and fixation requirements of the device on the equipment. On the base 4, mounting holes 9 are carefully opened.

[0117] The opening of the mounting hole 9 is not arbitrary, but has undergone rigorous engineering design and practical application considerations. From the aspect of dimensional specifications, parameters such as the diameter and depth of the mounting hole 9 are precisely calculated and optimized to ensure that it can be adapted to common fixing parts (such as bolts, screws, etc.) to achieve a stable and reliable connection. At the same time, the distribution position and quantity of the mounting holes 9 are also carefully planned, usually determined according to the shape and size of the base 4 and the overall force-bearing situation of the device, so as to ensure that the device can be evenly stressed after installation and avoid deformation or damage caused by excessive local stress.

[0118] The main function of the installation hole 9 is to provide an interface for the fixed installation of the automatic lifting knob device. In practical applications, an operator can pass a suitable fixing member through the installation hole 9 and tighten it in a corresponding threaded hole preset on the device housing or other support structures. In this way, the automatic lifting knob device can be firmly fixed in the target position, ensuring that the device will not become loose or displaced due to factors such as vibration and external impact during use, thus guaranteeing the stability and reliability of the device.

[0119] Although terms such as base and knob assembly are used more frequently in this application, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0120] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions generated by equivalent structure or equivalent process substitution or modification made based on the substantial concept of this application, using the content recorded in the text and drawings of the specification of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
