Description

Technical Field

[0001] The present invention relates to the technical field of capacitive pens, and specifically to a capacitive pen with AI voice interaction function and its method. Background Art

[0002] A capacitive pen is also a touch pen, which can be used in enterprise OA, ERP systems, collaboration systems or professional institutional intranets. Its appearance makes it convenient for people to use. It not only has a simple structure but also is easy to operate. With the popularization of electronic products, the usage scenarios of Bluetooth capacitive pens in combination with electronic devices such as tablets are becoming more and more extensive. Usually, before using a Bluetooth capacitive pen in combination with an electronic device for writing or drawing, it is necessary to first pair the Bluetooth capacitive pen with the electronic device and establish a Bluetooth connection;

[0003] However, the existing capacitive pens have relatively single functions and do not have a voice interaction function, resulting in relatively low practicality of the capacitive pens. Moreover, the existing capacitive pens are all integrally designed, making it difficult for users to replace the battery. After the capacitive pen is used for a long time, the battery capacity will surely decrease. When the battery capacity is too low, it will affect the normal use of the capacitive pen. At this time, users can only have the capacitive pen repaired by professionals, thus increasing the repair cost of the capacitive pen;

[0004] To solve the above problems, a capacitive pen with AI voice interaction function and its method are proposed in this application. Summary of the Invention

[0005] The present invention aims to provide a capacitive pen with AI voice interaction function and its method, mainly to solve the problems that the existing capacitive pens have relatively single functions and do not have a voice interaction function, resulting in relatively low practicality of the capacitive pens, and the existing capacitive pens are all integrally designed, resulting in relatively high repair costs of the capacitive pens.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] A capacitive pen with AI voice interaction function includes a pen barrel. The lower end of the pen barrel is detachably connected with a pen tip. A main board is fixedly installed inside the pen barrel. An AI voice interaction module is fixedly installed above the main board inside the pen barrel. A Bluetooth module, a data acquisition module, a processor and a storage module are fixedly installed on the main board;

[0008] AI voice interaction module: The AI voice interaction module further includes a microphone array and a speaker unit. The microphone array is used to collect user voice commands, and the speaker unit is used to output voice feedback;

[0009] Bluetooth module: The Bluetooth module supports Bluetooth 5.0 and above protocols, forms a closed-loop control with external devices through the Bluetooth module, and supports remote triggering and feedback of voice commands;

[0010] Data acquisition module: By integrating an array of pressure sensors, gyroscopes, accelerometers, and proximity sensors, it can obtain multi-dimensional data streams of the user's pen-holding pressure, tilt angle, three-dimensional posture, and touch distance in real time, with a sampling frequency of not less than 1 kHz;

[0011] Processor: Integrates a voice recognition engine and a natural language processing model, configured to execute the parsing and response of voice commands;

[0012] Storage module: Stores the voice command library and AI model parameters;

[0013] Inside the pen shaft, above the AI voice interaction module, a battery is detachably installed. Both ends of the battery are fixedly connected with first contacts. The top of the AI voice interaction module is fixedly connected with second contacts that match the first contacts. A plurality of through holes that match the AI voice interaction module are opened on the outer wall of the pen shaft, and the through holes are equidistantly distributed in a linear array on the pen shaft. The upper end of the pen shaft is detachably connected with a charging head. The lower end of the charging head is fixedly connected with an insertion block that matches the pen shaft. The lower end of the insertion block is fixedly connected with third contacts that match the first contacts. A limiting component is provided on the insertion block for fixing it. A charging interface for charging the battery is opened on the outer wall of the charging head. A dust-proof component for preventing dust from entering the inside of the charging interface is slidably connected to the outer wall of the charging head. An anti-drop component is provided at the upper end of the charging head.

[0014] The working principle and beneficial effects of the present invention:

[0015] 1. Working principle: When using the capacitive pen, insert one end of the charger into the charging interface, and then connect the charger to the power supply to charge the battery inside the pen barrel. The charging interface is a Type-c interface, which is applicable to most chargers on the market. After the battery is fully charged, unplug the charging cable. Bring the capacitive pen close to the electronic device, and the Bluetooth module on the main board inside the pen barrel will automatically match and connect with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally. The microphone array on the AI voice interaction module is used to collect the user's voice commands, and the speaker unit on the AI voice interaction module is used to output voice feedback. During the use of the capacitive pen, the data acquisition module can collect multi-dimensional data streams such as the pen pressure, angle, three-dimensional posture, and touch distance of the user. Then, decompose the signal of the pressure when the user uses the capacitive pen and process the data. The processor integrates a voice recognition engine and a natural language processing model, configured to execute the parsing and response of voice commands. The storage module can store the voice command library and AI model parameters. When the user needs to replace the battery inside the pen barrel, the limiting component can be released to disassemble the charging head, and then the battery inside the pen barrel can be taken out and replaced. Then, fix the charging head on the pen barrel through the limiting component, and the capacitive pen can be used normally.

[0016] 2. Beneficial effects:

[0017] (1) During the use of the capacitive pen, the AI voice interaction module can be used to collect the user's voice commands and output voice feedback. The data acquisition module can collect multi-dimensional data streams such as the pen pressure, angle, three-dimensional posture, and touch distance of the user. Then, decompose the signal of the pressure when the user uses the capacitive pen. The processor integrates a voice recognition engine and a natural language processing model, configured to execute the parsing and response of voice commands. The storage module can store the voice command library and AI model parameters. In this way, the function of AI voice interaction can be realized, thus effectively improving the practicability of the capacitive pen;

[0018] (2) The charging head is fixed at the upper end of the pen barrel through the limiting component, which is convenient for the user to replace the battery inside the pen barrel, thus effectively reducing the maintenance cost of the capacitive pen;

[0019] (3) After the capacitive pen accidentally falls to the ground during use, the anti-drop component set on the charging head can play a good protective role for the capacitive pen, thus effectively extending the service life of the capacitive pen;

[0020] (4) The charging interface set on the charging head can charge the battery inside the capacitive pen. After charging, the dust-proof component can play a good protective role for the charging interface, thus effectively preventing a large amount of dust from entering the charging interface and damaging the capacitive pen, and further effectively extending the service life of the capacitive pen.

[0021] Preferably, the limiting component includes a sliding cavity formed inside the plug block, and the sliding cavities are symmetrically arranged inside the plug block. A moving plate is slidably connected to the inside of each sliding cavity. The upper end of one side of the moving plate is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the inner wall of the sliding cavity. The upper end of the side of the moving plate away from the first spring is fixedly connected to a button, and the lower end of the side of the moving plate away from the first spring is fixedly connected to a wedge block. The side of the button away from the moving plate extends out of the charging head, and the button is slidably connected to the charging head. The side of the wedge block away from the moving plate extends out of the plug block, and the wedge block is slidably connected to the plug block. A limiting groove matching the wedge block is formed at the upper end of the pen barrel. When the user needs to replace the battery inside the pen barrel, press the two buttons on the charging head simultaneously. The wedge block can be driven to slide into the sliding cavity through the moving plate. When the wedge block disengages from the limiting groove on the pen barrel, the charging head can be disassembled. Then, the battery inside the pen barrel can be taken out and a new battery can be inserted into the pen barrel. Then, insert the plug block at the bottom of the charging head into the pen barrel. The inner wall of the pen barrel will squeeze the wedge block to automatically move into the sliding cavity. When the plug block completely enters the pen barrel, the moving plate drives the wedge block to move outwards under the action of the first spring, and the wedge block is engaged with the limiting groove on the pen barrel, so that the charging head can be fixed on the pen barrel, and the capacitive pen can be used normally. The advantage of this setting is that it is convenient for the user to replace the battery.

[0022] Preferably, the dust-proof component includes a sliding sleeve slidably connected to the outer wall of the charging head. Symmetrical guiding blocks are fixedly connected to the inner wall of the sliding sleeve. Guiding grooves matching the guiding blocks are formed on the outer wall of the charging head. Magnets are fixedly connected to both ends of the guiding blocks, and iron sheets attracted to the magnets are fixedly connected to both ends of the inner wall of the guiding groove. When charging the capacitive pen, slide the sliding sleeve upwards so that the magnet at the upper end of the guiding block is attracted to the iron sheet at the upper end of the inner wall of the guiding groove, and the charging interface can be exposed. Then, insert one end of the charger into the charging interface, and then connect the charger to the power supply to charge the battery inside the pen barrel. After charging is completed and the charging cable is unplugged, slide the sliding sleeve downwards so that the magnet at the lower end of the guiding block is attracted to the iron sheet at the lower end of the inner wall of the guiding groove to fix the sliding sleeve. At this time, the sliding sleeve can play a good role in protecting the charging interface, effectively preventing a large amount of dust from entering the charging interface and damaging the capacitive pen.

[0023] Preferably, the anti-drop component includes a cavity opened at the upper end of the charger head. A counterweight is fixedly connected to the bottom of the inner wall of the cavity. The top of the counterweight is fixedly connected to a second spring. The upper end of the second spring is fixedly connected to a buffer block. The upper end of the buffer block extends out of the cavity and is fixedly connected to a buffer pad. The buffer block is slidably connected to the inner wall of the cavity. When the capacitive pen accidentally drops during use, due to the action of the counterweight inside the cavity at the upper end of the charger head, the upper end of the capacitive pen can land first, effectively preventing the tip from landing first and being damaged. When the upper end of the capacitive pen contacts the ground, it will squeeze the buffer block to move inward into the cavity. Through the cooperation of the buffer block and the second spring, it can play a good protective role for the capacitive pen, thereby further extending the service life of the capacitive pen.

[0024] Preferably, a receiving cavity is opened on the outer wall of the pen barrel at the position of the through hole. A dust-proof plate is slidably connected inside the receiving cavity. When the capacitive pen is in use, slide the dust-proof plate upward to expose multiple through holes on the outer wall of the pen barrel, and the capacitive pen can be used normally. When the capacitive pen is not in use, slide the dust-proof plate downward. After sliding the dust-proof plate to the bottom of the receiving cavity, it can play a good role in blocking the through holes, effectively preventing dust from accumulating inside the through holes and affecting the normal use of the voice interaction function of the capacitive pen.

[0025] Preferably, symmetric sliders are fixedly connected to the lower end of the outer wall of the buffer block. A sliding groove matching the slider is opened on the inner wall of the cavity. When the buffer block is squeezed and slides inside the cavity, through the sliders provided at the lower end of the outer wall of the buffer block and the sliding grooves opened on the inner wall of the cavity, it can play a good role in limiting and guiding the buffer block. This not only makes the buffer block more stable when sliding inside the cavity, but also effectively prevents the buffer block from detaching from the inside of the cavity.

[0026] Preferably, a third spring is fixedly connected to the top of the AI voice interaction module. The upper end of the third spring abuts against the lower end of the battery. Through the third spring provided at the top of the AI voice interaction module, when the user removes the limiting component and disassembles the charger head, the battery will pop out a certain distance under the action of the third spring, making it more convenient to disassemble the battery.

[0027] Preferably, the microphone array adopts beamforming technology. The microphone array adopting beamforming technology filters out environmental background noise in the active noise reduction mode, locates the sound source direction through the phase array, and enhances the accuracy of far-field voice recognition.

[0028] Preferably, a rubber pad is fixedly connected to one side of the dust-proof plate. Anti-slip lines are opened on the rubber pad. Through the rubber pad provided on one side of the dust-proof plate, it can make the user's hand more comfortable when sliding the dust-proof plate up and down. Through the anti-slip lines opened on the rubber pad, it can increase the friction between the user's hand and the dust-proof plate, effectively preventing the user's hand from slipping when sliding the dust-proof plate.

[0029] Preferably, a capacitive pen with AI voice interaction function and its method include the following steps: A: Insert one end of the charger into the charging interface, then connect the charger to the power supply to charge the battery inside the pen barrel. After the battery is fully charged, unplug the charging cable, and the capacitive pen can be used normally; B: Bring the capacitive pen close to the electronic device, and the Bluetooth module on the main board inside the pen barrel will automatically match and connect with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally;

[0030] C: The microphone array on the AI voice interaction module is used to collect user voice commands, and the speaker unit on the AI voice interaction module is used to output voice feedback;

[0031] D: During the use of the capacitive pen, the data acquisition module can sample the multi-dimensional data stream of the user's pen pressure (0 - 2048g), angle (±60°), three-dimensional posture (XYZ axis), and touch distance (5 - 15mm). The sampling frequency is not less than 1kHz, and then decompose the signal of the user's pressure on the capacitive pen and process the data;

[0032] E: The processor integrates a speech recognition engine and a natural language processing model, configured to execute the parsing and response of voice commands;

[0033] F: The storage module can store the voice command library and AI model parameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Please refer to Figure 1-9, A capacitive pen with AI voice interaction function, including a pen shaft 1. The lower end of the pen shaft 1 is detachably connected with a pen tip 2, which facilitates the user to replace the pen tip 2. A main board 3 is fixedly installed inside the pen shaft 1. An AI voice interaction module 4 is fixedly installed above the main board 3 inside the pen shaft 1. The AI voice interaction module 4 also includes a microphone array 8 and a speaker unit 9. Through the microphone array 8, it is used to collect user voice commands. The microphone array 8 adopts beamforming technology. The microphone array 8 adopting beamforming technology filters out environmental background noise in the active noise reduction mode, locates the sound source direction through the phase array, and enhances the far-field voice recognition accuracy. Through the speaker unit 9, it is used to output voice feedback. A Bluetooth module 5, a data acquisition module 40, a processor 6, and a storage module 7 are fixedly installed on the main board 3. The Bluetooth module 5 supports Bluetooth 5.0 and above protocols. Through the Bluetooth module 5, a closed-loop control is formed with an external device, supporting the remote trigger and feedback of voice commands. Through an array integrating a pressure sensor, a gyroscope, an accelerometer, and a proximity sensor, a multi-dimensional data stream of the user's pen-holding pressure, tilt angle, three-dimensional posture, and touch distance is obtained in real time, and the sampling frequency is not less than 1 kHz. An integrated voice recognition engine and a natural language processing model are configured to execute the parsing and response of voice commands, store a voice command library and AI model parameters. A battery 10 is detachably installed above the AI voice interaction module 4 inside the pen shaft 1. Both ends of the battery 10 are fixedly connected with first contacts 11. The top of the AI voice interaction module 4 is fixedly connected with second contacts 12 matching the first contacts 11. After the battery 10 is installed inside the pen shaft 1, the first contacts 11 on the battery 10 contact the second contacts 12 on the AI voice interaction module 4. At this time, the spring battery 10 can supply power to the main board 3 and the AI voice interaction module 4. A plurality of through holes 38 matching the AI voice interaction module 4 are provided on the outer wall of the pen shaft 1, and the through holes 38 are evenly distributed in a linear array on the pen shaft 1. Through the plurality of through holes 38 provided on the pen shaft 1, the effect of the AI voice interaction module 4 collecting user voice commands and outputting voice feedback can be better. A receiving cavity 32 is provided on the outer wall of the pen shaft 1 at the position of the through holes 38. A dust-proof plate 33 is slidably connected inside the receiving cavity 32. One side of the dust-proof plate 33 is fixedly connected with a rubber pad 34, and anti-slip patterns are provided on the rubber pad 34. When the capacitive pen is in use, slide the dust-proof plate 33 upward to expose the plurality of through holes 38 on the outer wall of the pen shaft 1, and the capacitive pen can be used normally. When the capacitive pen is not in use, slide the dust-proof plate 33 downward. After sliding the dust-proof plate 33 to the bottom of the receiving cavity 32, it can play a good role in blocking the through holes 38, effectively preventing dust from accumulating inside the through holes 38 and affecting the normal use of the voice interaction function of the capacitive pen. The upper end of the pen shaft 1 is detachably connected with a charging head 13. The lower end of the charging head 13 is fixedly connected with a plug 14 matching the pen shaft 1. The lower end of the plug 14 is fixedly connected with a third contact 15 matching the first contacts 11.A limiting component for fixing the insertion block 14 is provided. A third spring 37 is fixedly connected to the top of the AI voice interaction module 4. The upper end of the third spring 37 abuts against the lower end of the battery 10. After the limiting component is released, the charging head 13 can be disassembled. Then, the battery 10 will pop out a certain distance under the action of the third spring 37, so that the battery 10 can be more easily disassembled and replaced. Then, the charging head 13 is fixed to the pen barrel 1 through the limiting component, and the capacitive pen can be used normally. A charging interface 16 for charging the battery 10 is provided on the outer wall of the charging head 13. A dust-proof component for preventing dust from entering the inside of the charging interface 16 is slidably connected to the outer wall of the charging head 13. The battery 10 inside the capacitive pen can be charged through the charging interface 16 provided on the charging head 13. After charging, the dust-proof component can play a good protective role for the charging interface 16, thereby effectively preventing a large amount of dust from entering the inside of the charging interface 16 and damaging the capacitive pen. An anti-drop component is provided at the upper end of the charging head 13. When the capacitive pen accidentally falls to the ground during use, the anti-drop component provided on the charging head 13 can play a good protective role for the capacitive pen, thereby effectively extending the service life of the capacitive pen.

[0047] Such as Figure 2 and Figure 8As shown in the figure, the limiting component includes a sliding cavity 17 formed inside the insertion block 14. The sliding cavities 17 are symmetrically arranged inside the insertion block 14. Inside each sliding cavity 17, there is a sliding connection with a moving plate 18. At the upper end of one side of the moving plate 18, a first spring 19 is fixedly connected. The other end of the first spring 19 is fixedly connected to the inner wall of the sliding cavity 17. At the upper end of the side of the moving plate 18 away from the first spring 19, a button 20 is fixedly connected. At the lower end of the side of the moving plate 18 away from the first spring 19, a wedge-shaped block 21 is fixedly connected. The side of the button 20 away from the moving plate 18 extends out of the charging head 13, and the button 20 is slidably connected to the charging head 13. The side of the wedge-shaped block 21 away from the moving plate 18 extends out of the insertion block 14, and the wedge-shaped block 21 is slidably connected to the insertion block 14. At the upper end of the pen barrel 1, a limiting groove 22 matching the wedge-shaped block 21 is provided. When the user needs to replace the battery 10 inside the pen barrel 1, press the two buttons 20 on the charging head 13 simultaneously. The wedge-shaped block 21 can be driven to slide into the sliding cavity 17 through the moving plate 18. When the wedge-shaped block 21 disengages from the limiting groove 22 on the pen barrel 1, the charging head 13 can be disassembled. Then, the battery 10 inside the pen barrel 1 can be taken out and a new battery 10 can be inserted into the pen barrel 1. Then, insert the insertion block 14 at the bottom of the charging head 13 into the pen barrel 1. The inner wall of the pen barrel 1 will squeeze the wedge-shaped block 21 to make it automatically move into the sliding cavity 17. When the insertion block 14 completely enters the pen barrel 1, the moving plate 18 drives the wedge-shaped block 21 to move outwards under the action of the first spring 19, and the wedge-shaped block 21 is engaged with the limiting groove 22 on the pen barrel 1, so that the charging head 13 can be fixed on the pen barrel 1, and the capacitive pen can be used normally. The advantage of this setting is that it is convenient for the user to replace the battery 10.

[0048] As Figure 2 , Figure 3 and Figure 8 shown, the dust-proof component includes a sliding sleeve 23 slidably connected to the outer wall of the charging head 13. Symmetric guiding blocks 24 are fixedly connected to the inner wall of the sliding sleeve 23. Guiding grooves 25 matching the guiding blocks 24 are provided on the outer wall of the charging head 13. Magnets 26 are fixedly connected to both ends of the guiding blocks 24. Iron sheets 27 attracted to the magnets 26 are fixedly connected to both ends of the inner wall of the guiding groove 25. When charging the capacitive pen, slide the sliding sleeve 23 upwards so that the magnet 26 at the upper end of the guiding block 24 is attracted to the iron sheet 27 at the upper end of the inner wall of the guiding groove 25, then the charging interface 16 can be exposed. Then insert one end of the charger into the charging interface 16, and then connect the charger to the power supply to charge the battery 10 inside the pen barrel 1. After charging is completed and the charging cable is unplugged, slide the sliding sleeve 23 downwards so that the magnet 26 at the lower end of the guiding block 24 is attracted to the iron sheet 27 at the lower end of the inner wall of the guiding groove 25 to fix the sliding sleeve 23. At this time, the sliding sleeve 23 can play a good protective role for the charging interface 16, thus effectively preventing a large amount of dust from entering the charging interface 16 and damaging the capacitive pen.

[0049] As Figure 4 shown, the anti-drop component includes a cavity 28 opened at the upper end of the charging head 13. A counterweight 39 is fixedly connected to the bottom of the inner wall of the cavity 28. The top of the counterweight 39 is fixedly connected to a second spring 30. The upper end of the second spring 30 is fixedly connected to a buffer block 29. The upper end of the buffer block 29 extends out of the cavity 28 and is fixedly connected to a buffer pad 31. The buffer block 29 is slidably connected to the inner wall of the cavity 28. Symmetric sliders 35 are fixedly connected to the lower end of the outer wall of the buffer block 29. A chute 36 matching the slider 35 is opened on the inner wall of the cavity 28. When the capacitive pen accidentally drops during use, due to the action of the counterweight 39 inside the cavity 28 at the upper end of the charging head 13, the upper end of the capacitive pen can land first, which can effectively prevent the tip 2 from landing first and causing damage to it. When the upper end of the capacitive pen contacts the ground, it will squeeze the buffer block 29 to move into the cavity 28. Through the cooperation of the buffer block 29 and the second spring 30, a better protection effect can be achieved on the capacitive pen, thereby further extending the service life of the capacitive pen.

[0050] As can be seen from the above, the specific implementation manner of the present invention is as follows:

[0051] When using the capacitive pen, slide the sliding sleeve 23 upward so that the magnet 26 at the upper end of the guiding block 24 attracts the iron sheet 27 at the upper end of the inner wall of the guiding groove 25, and then the charging interface 16 can be exposed. Insert one end of the charger into the charging interface 16, and then connect the charger to the power supply to charge the battery 10 inside the pen barrel 1. The charging interface 16 is a Type-c interface, which is applicable to most chargers on the market. After the battery 10 is fully charged, unplug the charging cable, and slide the sliding sleeve 23 downward so that the magnet 26 at the lower end of the guiding block 24 attracts the iron sheet 27 at the lower end of the inner wall of the guiding groove 25 to fix the sliding sleeve 23. At this time, the sliding sleeve 23 can provide good protection for the charging interface 16, effectively preventing a large amount of dust from entering the charging interface 16 and damaging the capacitive pen. Bring the capacitive pen close to the electronic device, and the Bluetooth module 5 on the main board 3 inside the pen barrel 1 will automatically match and connect with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally. The microphone array 8 on the AI voice interaction module 4 is used to collect the user's voice commands, and the speaker unit 9 on the AI voice interaction module 4 is used to output voice feedback. During the use of the capacitive pen, the data acquisition module 40 can collect the multi-dimensional data stream of the user's pen pressure, angle, three-dimensional posture and touch distance, and then decompose the signal of the pressure of the user using the capacitive pen and process the data. The processor 6 integrates a voice recognition engine and a natural language processing model, and is configured to execute the parsing and response of voice commands. The storage module 7 can store the voice command library and the AI model parameters. When the user needs to replace the battery 10 inside the pen barrel 1, press the two buttons 20 on the charging head 13 at the same time. The moving plate 18 can drive the wedge block 21 to slide into the sliding cavity 17. When the wedge block 21 disengages from the limiting groove 22 on the pen barrel 1, the charging head 13 can be disassembled. The battery 10 will pop out a certain distance under the action of the third spring 37, so that the battery 10 can be more easily disassembled and replaced. Insert the new battery 10 into the pen barrel 1, and then insert the plug 14 at the bottom of the charging head 13 into the pen barrel 1. The inner wall of the pen barrel 1 will squeeze the wedge block 21 to automatically move into the sliding cavity 17. When the plug 14 completely enters the pen barrel 1, the moving plate 18 drives the wedge block 21 to move outward under the action of the first spring 19, and makes the wedge block 21 engage with the limiting groove 22 on the pen barrel 1 to fix the charging head 13 on the pen barrel 1, and the capacitive pen can be used normally. When the capacitive pen accidentally drops during use, due to the action of the counterweight 39 inside the upper cavity 28 of the charging head 13, the upper end of the capacitive pen will land first, effectively preventing the nib 2 from landing first and being damaged. When the upper end of the capacitive pen contacts the ground, it will squeeze the buffer block 29 to move into the cavity 28. The cooperation of the buffer block 29 and the second spring 30 can provide good protection for the capacitive pen, further extending the service life of the capacitive pen.
