Description

Technical Field

[0001] This invention relates to the technical field of auscultation equipment, and more particularly to a wearable auscultation detection device for bronchiolitis obliterans. Background Technology

[0002] Bronchiolitis obliterans (BO) is a rare and fatal irreversible obstructive lung disease in pediatric clinics. It is a clinical syndrome caused by chronic airflow obstruction due to inflammation and fibrosis following damage to the small airways. The main clinical symptoms are recurrent or persistent wheezing, shortness of breath, and cough, with poor exercise tolerance. Wheezing and moist rales can be heard on lung auscultation. Clinical diagnosis and treatment mainly rely on chest imaging and pulmonary function tests. Pulmonary function tests show limited ventilation, while chest imaging shows lung hyperinflation, thinning of vascular markings, ground-glass opacities, and diffuse nodular or reticular nodular shadows without infiltrative shadows. High-resolution chest CT has characteristic changes and can show both direct and indirect signs.

[0003] However, current technologies, such as lung function tests and high-resolution chest CT scans, are difficult to monitor in real time due to technical limitations and radiation issues. While auscultation can be performed using a stethoscope, it lacks effective monitoring capabilities and methods, and it lacks means to capture airway airflow sounds. This results in the inability to fully acquire low-frequency respiratory sounds related to respiratory rate, high-frequency wheezing sounds, characteristic sounds of different degrees of obstruction, and cough signals. Consequently, basic test data is missing, making it impossible to screen for wheezing and obstruction based on abnormal respiratory rate, and it is also impossible to judge the condition based on wheezing duration and obstruction sound characteristics. This leads to frequent misdiagnosis and missed diagnosis, making it difficult to clarify the condition. Furthermore, children are often active and have smaller body sizes, so when the wiring is too long... Without a suitable way to manage excess wiring, it's easy for the wiring to become entangled in children's limbs or clothing. Children are active and energetic, and tangled wiring not only severely affects their normal activities and restricts their freedom of movement, but it can also interfere with the contact between the detection electrodes or sensors and the skin when children are moving around a lot, potentially even strangling the child, posing a significant safety hazard. On the other hand, if the wiring is too short and there is no flexible way to extend or adjust the structure, it will restrict the placement of the detection equipment, forcing children to maintain a specific, possibly uncomfortable, posture. This not only causes great inconvenience to children, but also easily interferes with the detection process, affecting the accuracy of the test results.

[0004] Furthermore, due to the significant limitations in the current diagnosis of BO disease, the use of wearable parts that fit the human torso, along with connected detection circuitry and related sensing and processing components, presents challenges. The wearable parts can help fix the device to the corresponding parts of the body to ensure the stability of the test, while the connected detection circuitry is used to transmit signals. The circuitry of this type of detector is usually rigid or lacks an effective contraction mechanism, and there is no dedicated constriction structure. If a vest-style design is adopted, although it has certain advantages in terms of overall wearability and allows the detection device to fit the body more stably, it has the disadvantage of high cost, which may be unaffordable for many patients' families, thus limiting its widespread application. Summary of the Invention

[0005] The purpose of this invention is to provide a wearable auscultation detection device for obliterative bronchiolitis, which solves the problems of ineffective circuit convergence and ineffective monitoring in linear auscultation detection devices.

[0006] The technical solution of this invention is as follows: a wearable auscultatory detector for bronchiolitis obliterans, comprising a strap and a display controller, a detector fixedly connected to the strap, a sleeve snapped onto the top of the detector, four sound acquisition units located on the outside of the detector, a storage unit rotatably connected to the middle of the detector, a connecting line connecting the sound acquisition units and the storage unit, a slotted shell fixedly connected inside the detector, a splicing sleeve fitted onto the outside of the storage unit, an adjusting component rotatably connected inside the detector, a support rod fixedly connected to the middle of the detector, and multiple components fixedly connected to the detector. The device includes an internal first guide wheel and a second guide wheel. The detector and the display controller are coupled together. The detector has a detection unit inside. Both the detection unit and the storage unit have Bluetooth units inside. The storage unit is located inside the slot shell. The connecting wire is wound around the outside of the second guide wheel and the first guide wheel. The storage unit is used to gather the connecting wire. The splicing sleeve includes a setting position. When the splicing sleeve is not in the setting position, the two sides of the splicing sleeve are slidably connected to the inside of the slot shell. When the splicing sleeve is in the setting position, the storage unit adjusts the length of the connecting wire through the splicing sleeve and the adjusting component.

[0007] Furthermore, the storage device includes a rotatable device rotatably connected inside the slot shell, four partitions vertically and equidistantly arranged and fixedly connected to the outside of the rotatable device, a threaded shaft fixedly connected to the bottom of the rotatable device, and one end of the connecting line connected between two partitions.

[0008] Furthermore, the adjusting component includes a disc rotatably connected to the outside of the support rod, a torsion spring connected between the support rod and the disc, and two arc-shaped blocks fixedly connected above the disc, the two arc-shaped blocks being symmetrical about the center of the disc.

[0009] Furthermore, the detector is equipped with an internal reminder unit, which is coupled to the detection unit. The detector has four holes and shafts. Two limiting blocks are fixedly connected to the detector near the disk. The two limiting blocks are symmetrical about the center of the disk and fit against the top surface of the disk.

[0010] Furthermore, two straight rods are fixedly connected to the bottom of the slot shell. The straight rods are symmetrically arranged about the central axis of the slot shell. Four support shafts are fixedly connected to the slot shell. Rotary wheels are sleeved on the outside of the support shafts. The four connecting lines are in contact with the corresponding rotary wheels.

[0011] Furthermore, the splicing sleeve includes a collar sleeved on the outside of the wire shaft, and two sleeve blocks are provided and fixedly connected to the outside of the collar. The sleeve blocks are slidably sleeved on the outside of the straight rod.

[0012] Furthermore, when the torsion spring is not deformed, the distance between the arc-shaped block and the limiting block is equal to the width of the arc-shaped block, the sleeve block is located between the limiting block and the arc-shaped block, and the bottom surface of the straight rod and the top surface of the arc-shaped block are on the same plane.

[0013] Furthermore, the adjusting member is fitted with the support rod, and the number of the second guide wheel, the first guide wheel, and the sound collector are equal.

[0014] Furthermore, the exterior of the rotator and the partition are both in contact with the interior of the slot shell, and both the exterior of the rotator and the partition and the interior of the slot shell are subjected to high friction treatment.

[0015] Furthermore, the center lines of the first guide wheel and the bore shaft coincide, the outer diameter of the second guide wheel is tangent to the center line of the first guide wheel, and the second guide wheel is located between the first guide wheel and the receiver.

[0016] The beneficial effects of this invention are:

[0017] Through dynamic adjustment of the line, the rotator of the receiver automatically retracts and releases the connecting line as the child moves. The sleeve slides and fits outside the straight rod to prevent the line from getting tangled or broken. When the splicing sleeve slides to the set position, the sleeve connects with the arc block. The length of the line can be precisely adjusted by the adjusting component to fit different children's chest circumferences. It is neither too tight and compresses the skin, nor too loose and causes the collector to shift.

[0018] By relying on acquisition, processing, and transmission, the system achieves improved monitoring accuracy through a complete link structure. This includes a full-area acquisition structure and a signal optimization processing structure, which simultaneously captures the frequency, duration, and intensity of breathing, coughing, and wheezing sounds to quickly locate lesion areas and provide comprehensive data support. In terms of signal optimization processing, the positioning subunit of the detection unit calibrates the position of the acquisition device to avoid movement deviation, the noise reduction subunit filters noise and retains key signals, and the identification subunit automatically identifies abnormal indicators based on the disease database and transmits data in real time via Bluetooth to reduce human error and lag. At the same time, the stable cooperation between the sleeve and the straight rod ensures smooth line transmission and guarantees the continuity of signal acquisition and transmission.

[0019] By using a sleeve block, when the collar tends to rotate, the sleeve block and the limit block make mechanical contact to block the collar from rotating, preventing it from detaching from the straight rod and causing structural failure. The high-friction mechanical treatment between the rotator and the slot shell prevents accidental changes in the circuit caused by equipment vibration or accidental contact by children through physical friction, protects the components from mechanical damage, and ensures the safety of equipment use in all aspects.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1-9 This invention provides a wearable auscultatory detector for bronchiolitis obliterans, comprising a strap 1 and a display controller 14, a detector 2 fixedly connected to the strap 1, a sleeve 3 snapped onto the top of the detector 2, four sound collectors 4 located on the outside of the detector 2, a storage unit 5 rotatably connected to the middle of the detector 2, a connecting line 6 connecting the sound collectors 4 and the storage unit 5, a slotted shell 7 fixedly connected inside the detector 2, a splicing sleeve 8 fitted onto the outside of the storage unit 5, an adjusting component 9 rotatably connected inside the detector 2, a support rod 10 fixedly connected to the middle of the detector 2, and multiple first guide wheels 11 and second guide wheels 12 fixedly connected inside the detector 2. The detector 2 and the display controller 14 are coupled together. A detection unit 21 is provided inside the detector 2. Both the detection unit 21 and the storage unit 5 are provided with Bluetooth units 13. The receiver 5 is located inside the slot shell 7. The connecting line 6 is wound around the outside of the second guide wheel 12 and the first guide wheel 11. The adjusting piece 9 is in contact with the support rod 10. The number of the second guide wheel 12, the first guide wheel 11 and the sound collector 4 are equal. The receiver 5 is used to gather the connecting line 6. The splicing sleeve 8 includes a setting position. When the splicing sleeve 8 is not in the setting position, the two sides of the splicing sleeve 8 are slidably connected inside the slot shell 7. When the splicing sleeve 8 is in the setting position, the receiver 5 adjusts the length of the connecting line 6 through the splicing sleeve 8 and the adjusting piece 9, so as to fit the child's body. By using low-frequency breathing sounds, high-frequency wheezing sounds, characteristic sounds of different degrees of obstruction and cough signals, early judgment and early intervention can be achieved, which helps doctors to make early diagnosis of BO disease, thereby improving the prognosis of BO children and improving their long-term quality of life. It can also be applied to the clinical auxiliary diagnosis of BO disease and provide a large amount of data collection for the treatment of BO.

[0035] The display controller 14 can be strapped to an adult's arm to facilitate observation of the detector 2's response. The display controller 14 is designed without physical keys and has four functions to control the detector 2.

[0036] Mode switching button: Single button design, used to switch between rales and coughs. Pressing the button will switch the mode with the indicator light on the back panel (blue corresponds to rales mode, orange corresponds to coughs mode). After switching, the detector 2 will automatically adjust the sensitivity of the sound collector 4 to adapt to the acquisition needs of different signals (if the rales signal is weak, the sensitivity will be automatically increased; if the coughs signal is strong, the sensitivity will be appropriately reduced to avoid overload).

[0037] Recording control button: When you need to manually trigger recording, press it again to pause. After pausing, you can confirm that the recording content is valid. Click the save button to save in seconds. When the save is successful, the backlight will flash three times to indicate that it is easy to play back and analyze later.

[0038] Parameter adjustment keys: Includes volume + / - keys and acquisition intensity keys. The volume of the prompt sound of detector 2 can be adjusted. The acquisition intensity key has three levels (weak / medium / strong). When you press to switch, the corresponding indicator light will light up. The weak level is suitable for the acquisition of subtle rallies in quiet environments, and the strong level is suitable for the capture of coughs in noisy environments, ensuring acquisition accuracy in different scenarios.

[0039] Emergency Pause Button: A separate red button that can be pressed and held for three seconds to immediately pause all data collection work of detector 2, adapting to emergencies (such as children resisting or the device being moved) and ensuring safety during use.

[0040] Specifically, four sound collectors 4 are set up, using medical-grade silicone detachable probes that are soft and non-irritating to the skin, avoiding resistance from children due to probe material discomfort. Simultaneous operation of multiple sound collectors 4 enables full-area lung auscultation, accurately capturing abnormal respiratory signals from different locations, and quickly locating lung lesions corresponding to wheezing, providing more comprehensive data support for diagnosis. The receiver 5 has a built-in Bluetooth unit 13, which can communicate in real-time with the Bluetooth unit 13 of the detector 2, transmitting information from the sound collectors 4 to the detection unit 21. The detection unit 21 includes a positioning unit, a noise reduction unit, and a recognition unit. The three sub-units of positioning, noise reduction, and recognition work together to improve the acquisition accuracy and recognition efficiency of abnormal signals from the bronchioles, avoiding noise interference, missed judgments, and misjudgments. When the splicing sleeve 8 is not in the set position, its two sides can slide freely along the track of the slot shell 7. At this time, the storage device 5 can automatically adjust the winding length according to the stretching requirements of the connecting wire 6 to adapt to the limb displacement of children during activities, avoiding the wire from breaking due to excessive stretching or restricting activities due to being too short. When the splicing sleeve 8 slides to the set position, the storage device 5 and the adjustment device 9 are linked. The length of the connecting wire 6 is finely adjusted by the adjustment device 9 to ensure that the sound collector 4 can fit the skin without causing discomfort to the child due to the tight wire.

[0041] Understandably, the sound collector 4 primarily detects respiratory rate, wheezing time, and respiratory obstruction. Respiratory rate is defined as the time it takes for a normal breath to occur between three and five seconds, which translates to a human respiratory rate of twelve to twenty-four breaths per minute. If the respiratory rate exceeds or falls below this range, it is considered abnormal, and the sound collector 4 records and detects this rate. Wheezing is mainly characterized by chest tightness, shortness of breath, rapid breathing, and a subjective feeling of difficulty or straining. Its typical features include a high-pitched whistling or wheezing sound during breathing, especially noticeable during exhalation, accompanied by coughing. Respiratory obstruction is mainly manifested by the respiratory rate ratio, the number of coughs, and the severity of the obstruction, resulting in different sounds.

[0042] Therefore, the sound acquisition device 4 is used to differentiate and record the sounds, thereby effectively detecting obliterative bronchiolitis through auscultation. In terms of signal capture, the three elements (sound acquisition device 4, sound acquisition device 4, and sound acquisition device 5) form a signal chain around the airway airflow sound. First, low-frequency breathing sounds are captured to calculate the respiratory rate. Abnormalities are the starting point for investigation. When there is airway spasm, high-frequency wheezing sounds are captured and the duration of wheezing is recorded. When the obstruction worsens, the degree of obstruction is judged according to the changes in sound intensity and frequency (mild: low-frequency friction rub, moderate: mid-frequency wheezing, severe: high-frequency whistling). Cough signals are also captured. In the analysis, the data of the three elements are mutually corroborated: when normal, the three elements are harmonious; in the early stage, they are all slightly abnormal; as the disease progresses, they are synchronously aggravated; when the obstruction is severe, the frequency may decrease, but wheezing is prolonged and the sound is abnormal, avoiding misjudgment by a single indicator. In terms of result verification, cross-validation reduces misdiagnosis: only high frequency or only wheezing sounds are not usually related to this disease. Only when all three elements are abnormal and superimposed are they judged to be related to this disease, combined with the respiratory ratio.

[0043] Reference Figures 2-6 The storage container 5 includes a rotator 51 rotatably connected inside the slot shell 7, four partitions 52 vertically and equidistantly arranged and fixedly connected to the outside of the rotator 51, a screw 53 fixedly connected to the bottom of the rotator 51, and one end of the connecting line 6 connected between two partitions 52.

[0044] Specifically, in the storage unit 5, independent cable storage slots are formed between two adjacent partitions 52. The inner wall of the storage slot is covered with a layer of medical-grade silicone pad. The surface of the silicone pad has anti-slip texture to enhance the fit with the connecting cable 6 and prevent the cable from sliding freely in the slot. Each storage slot also has a miniature limiting protrusion at the bottom. The protrusion is made of silicone, which is soft and elastic. When the connecting cable 6 is shortened to its shortest state, the terminal will contact the limiting protrusion. The limiting protrusion cushions the connecting cable 6 with its own elasticity, preventing the terminal from being damaged by a hard collision with the bottom of the storage slot.

[0045] Reference Figures 1-7 The adjusting component 9 includes a disc 91 rotatably connected to the outside of the support rod 10, a torsion spring 92 connected between the support rod 10 and the disc 91, and two arc-shaped blocks 93 fixedly connected above the disc 91. The two arc-shaped blocks 93 are symmetrical about the center of the disc 91. The torsion spring 92 has a low elastic coefficient and can be stretched at will.

[0046] The rotator 51 rotates in two directions: clockwise and counterclockwise. Clockwise rotation of the rotator 51 retracts the connecting line 6, while counterclockwise rotation releases the connecting line 6. When the splicing sleeve 8 reaches the set position, it will engage with the adjusting component 9. At the same time, the splicing sleeve 8 is no longer restricted by the slot shell 7. Consequently, when the connecting line 6 is pulled, it will cause the rotator 51 to rotate counterclockwise. As the rotator 51 rotates counterclockwise, the splicing sleeve 8, no longer restricted by the slot shell 7, will rotate accordingly. The device 51 rotates synchronously, which in turn causes the splicing sleeve 8 to rotate the disc 91. When the disc 91 rotates, the torsion spring 92 will undergo elastic deformation with the rotation of the disc 91, storing elastic potential energy and releasing the connecting line 6. When the connecting line 6 is no longer stretched, the torsion spring 92 will release elastic potential energy, causing the disc 91 to automatically return to its initial position. The splicing sleeve 8 and the rotator 51 will return to their initial positions synchronously, tightening the connecting line 6 and making fine adjustments to the connecting line 6 to achieve changes in the length of the connecting line 6, ensuring the stability of the line length. On the other hand, no manual adjustment is required.

[0047] Reference Figures 2-6 The detector 2 is equipped with an internal reminder unit 22, which is coupled to the detection unit 21. The detector 2 is provided with four hole shafts 201. Two limit blocks 202 are fixedly connected to the detector 2 near the disk 91. The two limit blocks 202 are symmetrical about the center of the disk 91 and are in contact with the top surface of the disk 91.

[0048] When the detection unit 21 detects abnormal symptoms such as respiratory rate exceeding the normal range, sudden increase in cough intensity, or prolonged wheezing, it immediately sends a trigger signal to the reminder unit 22. At this time, the reminder unit 22 will activate the corresponding reminder according to the level of abnormality. For mild abnormalities, only the green LED indicator light will be lit, flashing once every three seconds to avoid disturbing the child. For moderate abnormalities, the green indicator light will turn yellow and vibrate the motor to remind parents to pay attention. For severe abnormalities, the yellow indicator light will switch to red, and the buzzer will emit an intermittent low-volume warning sound, with the volume controlled below 50 decibels, to avoid stimulating the child and ensure that parents or medical staff can quickly notice the abnormality. In addition, the hole shaft 201 provides a guiding and protective channel for the connecting cable 6. When the connecting cable 6 extends from the storage slot of the receiver 5, it will first pass through the corresponding hole shaft 201 and then connect to the sound collector 4.

[0049] Reference Figures 2-8 Two straight rods 71 ​​are fixedly connected to the bottom of the slot shell 7. The straight rods 71 ​​are symmetrically arranged about the central axis of the slot shell 7. Four support shafts 72 are fixedly connected to the slot shell 7. Rotary wheels 701 are sleeved on the outside of the support shafts 72. The four connecting lines 6 are in contact with the corresponding rotary wheels 701.

[0050] Specifically, two straight rods 71 ​​are fixedly connected to the inner bottom of the slot shell 7. The two rods are symmetrically distributed about the central axis of the slot shell 7 and are perpendicular to the bottom of the slot shell 7. The straight rods 71 ​​provide guidance for the sliding of the splicing sleeve 8. When the rotator 51 rotates, the straight rods 71 ​​restrict the splicing sleeve 8, and the splicing sleeve 8 cannot rotate. Then the threaded shaft 53 rotates, thereby using the roller principle to make the splicing sleeve 8 move up and down, ensuring that the splicing sleeve 8 can slide accurately to the set position and achieve stable linkage with the adjusting component 9. The rotating wheel 701 is made of medical-grade wear-resistant plastic. There is a miniature bearing between the inner wall and the support shaft 72 to ensure that the rotating wheel 701 can rotate flexibly around the support shaft 72 without obvious jamming during the rotation. This optimizes the winding and releasing path of the connecting line 6, reduces line wear, and ensures that the connecting line 6 always moves along a fixed path during winding or releasing, avoiding line deviation or entanglement due to pulling.

[0051] Reference Figures 2-7 The splicing sleeve 8 includes a collar 81 sleeved on the outside of the screw shaft 53, and two sleeve blocks 82 fixedly connected to the outside of the collar 81. The sleeve blocks 82 are slidably sleeved on the outside of the straight rod 71.

[0052] When the torsion spring 92 is not deformed, the distance between the arc block 93 and the limiting block 202 is equal to the width of the arc block 93, the sleeve block 82 is located between the limiting block 202 and the arc block 93, and the bottom surface of the straight rod 71 and the top surface of the arc block 93 are on the same plane.

[0053] Specifically, the collar 81 is an annular structure with an inner diameter that matches the outer diameter of the screw shaft 53, allowing it to be tightly fitted onto the outside of the screw shaft 53 and to slide freely along the axial direction of the screw shaft 53. Two sleeve blocks 82 are fixedly connected to the outer wall of the collar 81. The two sleeve blocks 82 are symmetrically distributed about the central axis of the collar 81 and correspond one-to-one with the two straight rods 71 ​​at the bottom of the slot shell 7. Each sleeve block 82 has a through hole at its center that matches the straight rod 71. When the splicing sleeve 8 needs to be moved, the screw shaft 53 rotates, causing the sleeve blocks 82 to slide along the axial direction of the straight rods 71. When the rotator 51 drives the screw shaft 53 to rotate clockwise, the screw shaft 53 will generate a rotational driving force on the collar 81 through the threaded transmission. If there is an external limit on the collar 81, it will rotate synchronously with the screw shaft 53, causing the collar 81 to move up and down along the screw shaft 53 and eventually disengage from the stable fit with the straight rods 71. The limit block 202, through its connection with the sleeve... The positional fit of block 82 directly constrains the clockwise rotation of collar 81. When collar 81 tends to rotate clockwise, block 82 contacts the side wall of limit block 202. Limit block 202 blocks the rotation of block 82 through its own fixing structure, thereby restricting the rotational movement of collar 81. Under the constraint of limit block 202, collar 81 cannot rotate with rotator 51 and can only convert the rotational driving force of screw 53 into an upward movement along the axial direction of screw 53. When collar 81 moves up to the point where block 82 re-fits with the upper part of straight rod 71, straight rod 71 will again limit block 82, restricting collar 81 from continuing to move upward or deviate, so that collar 81 is back in a stable state. This ensures that splicing sleeve 8 always maintains a stable fit with screw 53 and straight rod 71, achieving the accuracy and safety of connecting line 6 length adjustment, and effectively maintaining the stable operation of the internal structure of the equipment.

[0054] Reference Figures 1-9 The exterior of the rotator 51 and the partition 52 are both in contact with the interior of the slot shell 7. The exterior of the rotator 51 and the partition 52 and the interior of the slot shell 7 are both treated with high friction. Specifically, a sandblasting process can be used to form a rough texture on the contact surface, or a medical-grade rubber coating with a high coefficient of friction can be sprayed to prevent accidental rotation due to equipment vibration or slight touch by children, and to ensure that the length of the connecting line 6 remains stable.

[0055] Reference Figures 1-9 The center lines of the first guide wheel 11 and the hole shaft 201 coincide, and the outer diameter of the second guide wheel 12 is tangent to the center line of the first guide wheel 11. The second guide wheel 12 is located between the first guide wheel 11 and the receiver 5. The surfaces of the first guide wheel 11 and the second guide wheel 12 are made of smooth and wear-resistant polyurethane material. The connecting line 6 can reduce the friction between the line and the component through the rotation of the guide wheel, which can limit the connection line 6, so that the connection line 6 and the hole shaft 201 can be smoothly contracted and extended, ensuring that the line always moves along a fixed trajectory when it is being bundled and stretched.

[0056] The working principle of this invention is as follows: In use, the detector 2 is first fixed to the user's torso in the corresponding lung area using an elastic and breathable strap 1. The strap 1 can be flexibly adjusted according to body shape to ensure that the detector 2 fits snugly but does not restrict movement. The four sound collectors 4 are stretched to fit the corresponding areas of the upper and lower lobes of the lungs. When the four sound collectors 4 are stretched, the connecting wire 6 is pulled, and the tension is transmitted to the rotator 51 through the connecting wire 6. The rotator 51 rotates counterclockwise to release the circuit. At this time, the collar 81 is not in the set position. Positioning: Sleeve 82 can slide freely along straight rod 71, and collar 81 cannot rotate synchronously with rotator 51. At this time, rotator 51 rotates, causing connecting wire 6 to be released from storage slot. Connecting wire 6 extends along the trajectory of rotating wheel 701, first guide wheel 11, and second guide wheel 12, adapting to the displacement of sound acquisition device 4 through hole shaft 201 to avoid excessive pulling and breakage of the line. When moving collar 81 slides along threaded shaft 53 to the set position, sleeve 82 connects with arc block 93, splicing sleeve 8 and adjusting component 9. A linkage is formed, and without the forced limiting of the slotted shell 7, when the connecting wire 6 is stretched, the rotator 51 rotates counterclockwise, and the collar 81 rotates accordingly, squeezing the arc-shaped block 93, causing the disc 91 to rotate. The torsion spring 92 undergoes elastic deformation as the disc 91 rotates, at which point the connecting wire 6 is released. When the connecting wire 6 loses its tension, the torsion spring 92 causes the disc 91 and the collar 81 to rotate back. The collar 81 drives the threaded shaft 53 to rotate clockwise, which in turn drives the rotator 51 to clockwise reel in the connecting wire 6, and the excess wire is wound up. Within the storage slot of the partition 52, the connecting wire 6 can be finely adjusted. When the connecting wire 6 needs to be completely retracted, the rotating device 51 is rotated to drive the screw 53 to rotate clockwise. The sleeve block 82 contacts the side wall of the limiting block 202. The limiting block 202 constrains the clockwise rotation of the collar 81. The screw 53 generates an upward driving force on the collar 81 through the threaded transmission. The limiting block 202 blocks the rotation of the sleeve block 82, so that the collar 81 only moves up and down along the axial direction of the screw 53, and re-engages with the upper section of the straight rod 71 to maintain structural stability.
