[0025] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0026] The wire take-up device is usually provided with a torsion spring. When the wire take-up device is releasing the wire, the wire can be pulled out of the wire take-up device. The torsion spring stores elastic potential energy. When the wire take-up device is storing the wire, the torsion spring releases the stored elastic potential energy to recycle the wire into the wire take-up device. However, in the related art, when the wire take-up device stores the wire, the wire take-up device can usually only completely recycle the wire, or recycle the wire to a certain length. The length of the wire cannot be adjusted arbitrarily during the process of storing the wire, so that the degree of freedom of the wire take-up device to store or release the wire is not high, which makes the convenience of the wire take-up device to store or release the wire insufficient, affecting the user experience. In addition, the torsion spring in the wire take-up device also increases the cost.
[0027] In view of this, the embodiment of the present application provides a wire-taking device, which does not need to design a torsion spring, so that the cost of the wire-taking device of the present application is low. The knob cover 1 is rotated to drive the first transmission member 3 to rotate, and the rotating first transmission member 3 can drive the second transmission member 4 to engage with the first rack 21 of the winding member 2, so that the winding member 2 also rotates accordingly to wind up and store the wire. The wire can be stored to any length, and the wire-taking device is in a wire-taking state; the knob cover 1 is rotated in the opposite direction to drive the first transmission member 3 to rotate in the opposite direction, and the first transmission member 3 rotating in the opposite direction can drive the second transmission member 4 to disengage from the first rack 21 of the winding member 2, so that the winding member 2 is unconstrained in the rotation direction, and the winding member 2 is in a free-rotating wire-releasing state, and the wire can be pulled out of the winding device to any length, and the winding device is in a free wire-releasing state, which makes the winding device have a higher degree of freedom in storing or releasing the wire, so as to improve the convenience of storing or releasing the wire by the winding device.
[0028] Figure 1 Schematic diagram of the structure of a storage device in one embodiment of the present application is shown. Figure 2~Figure 5The wire-taking device of the present application comprises a knob cover 1, a first transmission member 3, a second transmission member 4 and a winding member 2. The winding member 2 is provided with a transmission cavity 2a, the cavity wall of the transmission cavity 2a is formed with a first ring-shaped rack 21, the first transmission member 3 is arranged in the transmission cavity 2a, the knob cover 1 is transmission-connected with the first transmission member 3, the knob cover 1 can operably drive the first transmission member 3 to rotate, the knob cover 1 comprises a cover body 11, the cover body 11 is arranged in the transmission cavity 2a, the second transmission member 4 is arranged in the transmission cavity 2a, along the radial direction of the winding member 2, the second transmission member 4 is located between the first transmission member 3 and the first rack 21, the knob cover 1 can operably drive the first transmission member 3 to rotate to the first position or the second position, when the first transmission member 3 is located in the first position, the second transmission member 4 is disengaged from the first rack 21; when the first transmission member 3 is located in the second position, the first transmission member 3 drives the second transmission member 4 to move along the radial direction of the winding member 2 to drive the second transmission member 4 to engage with the first rack 21.
[0029] Exemplarily, the materials of the knob cover 1 , the first transmission member 3 , the second transmission member 4 and the winding member 2 are not limited, and they can all be plastic or metal, for example.
[0030] For example, Figure 6 and Figure 7 The direction indicated by R1 is counterclockwise, that is, the rotation direction of the first transmission member 3 from the second position to the first position.
[0031] For example, Figure 8 and Fig. 9 The direction indicated by R2 is clockwise, that is, the rotation direction of the first transmission member 3 from the first position to the second position.
[0032] It should be explained that the first position and the second position of the first transmission member 3 are both relative positions relative to the second transmission member 4 .
[0033] For example, see Figure 4 , Figure 6 and Figure 7 When the first transmission member 3 is located at the first position, the second transmission member 4 is disengaged from the first rack 21 of the winding member 2, so that the winding member 2 is in a freely rotating line-releasing state, and the wire wound on the winding member 2 can be freely pulled out to a preset length. When the first transmission member 3 is located at the first position and then the knob cover 1 is rotated counterclockwise, the knob cover 1 drives the first transmission member 3 to rotate counterclockwise, so that the first transmission member 3 is still located at the first position relative to the second transmission member 4, and the second transmission member 4 remains disengaged from the first rack 21 of the winding member 2, so that the winding member 2 is still in a freely rotating line-releasing state, that is, in this case, rotating the knob cover 1 counterclockwise will not affect the freely rotating line-releasing state of the winding member 2. Please refer to Figure 5 , Figure 8 and Fig. 9When the first transmission member 3 is located at the first position and the knob cover 1 is rotated in the clockwise direction, the knob cover 1 drives the first transmission member 3 to rotate clockwise from the first position to the second position, and the first transmission member 3 drives the second transmission member 4 to move radially along the winding member 2 to drive the second transmission member 4 to engage with the first rack 21, so that the winding member 2 is converted from the free-rotating unwinding state to the winding state. When the first transmission member 3 is located at the second position, the second transmission member 4 engages with the first rack 21, so that the winding member 2 also rotates accordingly to wind up the wire, and the wire can be stored to a preset length. When the first transmission member 3 is located at the second position and the knob cover 1 is rotated in the counterclockwise direction, the knob cover 1 drives the first transmission member 3 to rotate counterclockwise, so that the first transmission member 3 rotates from the second position relative to the second transmission member 4 to the first position, and the second transmission member 4 is disengaged from the first rack 21, so that the winding member 2 is converted from the winding state to the free-rotating unwinding state. When the first transmission member 3 is located at the second position and the knob cover 1 is rotated in the clockwise direction, the knob cover 1 drives the first transmission member 3 to rotate clockwise, so that the first transmission member 3 is still located at the second position relative to the second transmission member 4, and the first transmission member 3 can drive the second transmission member 4 to maintain engagement with the first rack 21, so that the winding member 2 is still in the winding state to store the wire, that is, in this case, rotating the knob cover 1 clockwise can make the winding member 2 continue to rotate clockwise to continuously wind and store the wire.
[0034] Exemplarily, the wire collection device of the present application can be used to store wires such as headphone wires, speaker data wires, and speaker power wires. For example, the headphone wires can be sports headphone wires, ear-hanging headphone wires, sports headphone wires, and open headphone wires; the speaker data wires can be computer speaker data wires, desktop speaker data wires, and portable speaker data wires; and the speaker power wires can be Bluetooth speaker power wires, voice-controlled speaker power wires, smart interactive speaker power wires, and artificial intelligence noise reduction speaker power wires.
[0035] In the embodiment of the present application, the knob cover 1 can be operably driven to drive the first transmission member 3 to rotate to the first position or the second position. When the first transmission member 3 is in the first position, the second transmission member 4 is disengaged from the first rack 21, so that the winding member 2 can be in a freely rotating unwinding state, and the wire can be pulled out of the wire-winding device to a preset length. When the first transmission member 3 is in the second position, the first transmission member 3 drives the second transmission member 4 to move radially along the winding member 2 to drive the second transmission member 4 to engage with the first rack 21, so that the knob cover 1 can drive the winding member 2 to rotate so that the winding member 2 is in a wire-winding state, and the winding member 2 can wind and store a preset length of wire. On the one hand, the wire-winding device of the present application can basically adjust the length of the exposed wire by operating the knob cover 1, so that the wire-winding device has a high degree of freedom in adjusting the length of the wire, which is conducive to improving the convenience of the wire-winding device in storing or releasing the wire; on the other hand, there is no torsion spring in the wire-winding device of the present application, and the structure is relatively simple, which is conducive to reducing the cost of the wire-winding device.
[0036] In one embodiment, please refer to Figure 2 , Figure 4~Figure 9 The first transmission member 3 includes a transmission shaft 31, the knob cover 1 is connected to the transmission shaft 31, the transmission shaft 31 has a first protrusion 311, and the first protrusion 311 protrudes from the transmission shaft 31 along the radial direction of the transmission shaft 31. The second transmission member 4 includes a transmission ring 41 and a transmission tooth 42. The transmission tooth 42 is located on the side of the transmission ring 41 close to the first rack 21 along the radial direction of the winding member 2. The first protrusion 311 abuts against the transmission ring 41, and the abutting surface between the transmission ring 41 and the first protrusion 311 is a curved surface, and the curvature of the abutting surface between the transmission ring 41 and the first protrusion 311 gradually increases in the direction toward the transmission tooth 42.
[0037] For example, see Figure 2 , Figure 4~Figure 9 The transmission tooth 42 is located at one end of the transmission ring 41 along the circumferential direction of the winding member 2.
[0038] For example, see Figure 4 , Figure 6 and Figure 7 When the first transmission member 3 is located at the first position, the knob cover 1 is rotated clockwise. During the process of the knob cover 1 driving the transmission shaft 31 of the first transmission member 3 to rotate clockwise, the first protrusion 311 always contacts the transmission ring 41. The curvature of the contact surface between the transmission ring 41 and the first protrusion 311 gradually increases in the clockwise direction, so that during the process of the first transmission member 3 rotating clockwise relative to the second transmission member 4, the first protrusion 311 of the first transmission member 3 drives the transmission ring 41 to move along the radial direction of the winding member 2 until the transmission teeth 42 are fully meshed with the first rack 21, and the first transmission member 3 rotates to the second position relative to the second transmission member 4. Please refer to Figure 5 , Figure 8 and Fig. 9When the first transmission member 3 is located in the second position and the knob cover 1 continues to be rotated in the clockwise direction to drive the transmission shaft 31 to rotate clockwise, the radial movement of the transmission tooth 42 along the winding member 2 is blocked by the first rack 21, and the first protrusion 311 and the first rack 21 constrain the second transmission member 4 to limit its position. On the one hand, the first protrusion 311 can drive the second transmission member 4 to rotate clockwise, and on the other hand, the transmission tooth 42 is more firmly engaged in the first rack 21 to drive the winding member 2 to rotate clockwise, so that the winding member 2 can wind and store the wire clockwise. When the first transmission member 3 is located in the second position and the knob cover 1 continues to be rotated counterclockwise to drive the transmission shaft 31 to rotate counterclockwise, the curvature of the abutment surface between the transmission ring 41 and the first protrusion 311 gradually decreases in the counterclockwise direction, so that the first transmission member 3 is located in the second position and in the process of rotating counterclockwise relative to the second transmission member 4, the restraining ability of the first protrusion 311 on the second transmission member 4 gradually decreases. When the wire is pulled out from the wire-winding device, the winding member 2 rotates counterclockwise, and the transmission tooth 42 can be disengaged from the first rack 21 when the limiting effect of the first protrusion 311 is lost, so that the winding member 2 is in a freely rotating unwinding state.
[0039] In the embodiment of the present application, the curvature of the contact surface between the transmission ring 41 and the first protrusion 311 gradually increases in the direction toward the transmission tooth 42, so that the distance between the contact surface between the transmission ring 41 and the first protrusion 311 and the rotation center of the take-up device gradually decreases in the direction toward the transmission tooth 42, and then when the transmission shaft 31 rotates in the direction toward the transmission tooth 42, the first protrusion 311 can drive the transmission ring 41 to move radially along the winding member 2, so that the transmission tooth 42 is meshed with the first rack 21. The first protrusion 311 and the first rack 21 constrain the second transmission member 4 to limit the position, so that the second transmission member 4 can transmit the torsional force of the knob cover 1 to the winding member 2, so as to drive the winding member 2 to rotate to wind up the wire, which is conducive to improving the transmission capacity and stability of the second transmission member 4. In addition, when the first protrusion 311 is engaged with the first rack 21, the wire is pulled under this condition, and the winding member 2 has a tendency to rotate in the opposite direction. Under the restriction of the knob cover 1, the first transmission member 3 and the second transmission member 4, it is beneficial to restrict the winding member 2 to a preset position, and then it is beneficial to fix the wire to a preset length.
[0040] It is understandable that the curvature of the contact surface between the transmission ring 41 and the first protrusion 311 is not limited to gradually increasing in the direction toward the transmission tooth 42. Exemplarily, the curvature of the contact surface between the transmission ring 41 and the first protrusion 311 remains unchanged in the direction toward the transmission tooth 42, and during the rotation of the first protrusion 311 in the direction toward the transmission tooth 42, the length of the first protrusion 311 gradually increases to drive the second transmission member 4 to move in the radial direction of the winding member 2, thereby causing the transmission tooth 42 to mesh with the first rack 21.
[0041] In one embodiment, please refer to Figure 2 , Figure 4~Figure 9 The transmission shaft 31 also has a second protrusion 312, which protrudes from the transmission shaft 31 in the radial direction of the transmission shaft 31. When the first transmission member 3 is located in the first position, the second protrusion 312 is disengaged from the end of the transmission ring 41 away from the transmission tooth 42. When the first transmission member 3 is located in the second position, the second protrusion 312 abuts against the end of the transmission ring 41 away from the transmission tooth 42.
[0042] For example, see Figure 6~Figure 9 The second protrusions 312 and the first protrusions 311 are evenly spaced apart along the circumference of the transmission shaft 31 .
[0043] In the embodiment of the present application, when the first transmission member 3 is in the first position, the second protrusion 312 is disengaged from the end of the transmission ring 41 away from the transmission tooth 42, and when the knob cover 1 drives the first transmission member 3 to rotate from the first position toward the second position, the second protrusion 312 also rotates accordingly. When the first transmission member 3 is in the second position, the second protrusion 312 abuts against the end of the transmission ring 41 away from the transmission tooth 42, so that the second protrusion 312, the first protrusion 311 and the first rack 21 jointly constrain and limit the second transmission member 4, so that the second transmission member 4 can transmit the torsional force of the knob cover 1 to the winding member 2, so as to drive the winding member 2 to rotate to wind and store the wire, which is beneficial to improving the transmission capacity and stability of the second transmission member 4.
[0044] It is understandable that the transmission shaft 31 is not limited to being provided with the second protrusion 312. For example, the transmission shaft 31 may also have only the first protrusion 311.
[0045] In one embodiment, please refer to Figure 4~Figure 9 The first transmission member 3 also includes a transmission disk 32 and a transmission rod 33. The transmission disk 32 is connected to the outer peripheral side of the transmission shaft 31. The transmission rod 33 protrudes from the side of the transmission disk 32 close to the cover body 11. The transmission ring 41 has an arc groove 41a. The transmission rod 33 is inserted into the arc groove 41a. When the first transmission member 3 is located in the first position, the transmission rod 33 abuts against one end of the arc groove 41a away from the transmission tooth 42. When the first transmission member 3 is located in the second position, the transmission rod 33 abuts against one end of the arc groove 41a close to the transmission tooth 42.
[0046] Exemplarily, the cross-sectional shape of the transmission rod 33 is not limited. For example, the cross-sectional shape of the transmission rod 33 may be circular or square.
[0047] For example, see Figure 4 , Figure 6In Figures 7 and 8, when the first transmission member 3 is in the first position, the transmission rod 33 abuts against the end of the arc groove 41a away from the transmission tooth 42, and the knob cover 1 then drives the first transmission member 3 to rotate counterclockwise, so that the transmission rod 33 abuts against the groove wall of the arc groove 41a to drive the second transmission member 4 to rotate counterclockwise synchronously with the first transmission member 3. When the first transmission member 3 is in the first position, the knob cover 1 then drives the first transmission member 3 to rotate clockwise, and the transmission rod 33 rotates relative to the second transmission member 4 in the arc groove 41a. Please refer to Figure 5 , Figure 8 and Fig. 9 When the first transmission member 3 rotates to the second position, the transmission rod 33 abuts against one end of the arc groove 41a close to the transmission tooth 42, so that the transmission shaft 31, the second protrusion 312, the first protrusion 311 and the first rack 21 jointly constrain and limit the second transmission member 4.
[0048] In the embodiment of the present application, when the first transmission member 3 is located in the first position and the transmission rod 33 rotates in a direction away from the transmission tooth 42 under the drive of the knob cover 1, the transmission rod 33 abuts against one end of the arc groove 41a away from the transmission tooth 42 and can drive the second transmission member 4 to rotate synchronously with the first transmission member 3, so as to disengage the transmission tooth 42 from the first rack 21, so that the winding member 2 is in a freely rotating line-releasing state; when the first transmission member 3 is located in the second position and rotates in a direction toward the transmission tooth 42 under the drive of the knob cover 1, the transmission rod 33, the second protrusion 312, the first protrusion 311 and the first rack 21 jointly constrain and limit the second transmission member 4, so that the second transmission member 4 can transmit the torsional force of the knob cover 1 to the winding member 2, so as to drive the winding member 2 to rotate to wind and store the wire, which is beneficial to improve the transmission capacity and stability of the second transmission member 4.
[0049] It can be understood that the first transmission member 3 is not limited to including the transmission plate 32 and the transmission rod 33, and the transmission ring 41 is not limited to having the arc groove 41a.
[0050] In one embodiment, please refer to Figure 3 , Figure 7 and Fig. 9 The cover body 11 has a semi-lunar groove 11 a, and the semi-lunar groove 11 a is used to avoid the end of the transmission rod 33 away from the transmission plate 32.
[0051] In the embodiment of the present application, the semi-lunar groove 11a of the cover body 11 is used to avoid the end of the transmission rod 33 away from the transmission plate 32, so that the length of the transmission rod 33 can be extended as much as possible, so as to improve the reliability of the abutment between the transmission rod 33 and the arc groove 41a, which is beneficial to reduce the possibility of failure of the abutment between the transmission rod 33 and the arc groove 41a.
[0052] It is understood that the cover body 11 is not limited to having the semi-lunar groove 11 a.
[0053] In one embodiment, please refer to Figure 2 , Figure 6~Figure 9 The knob cover 1 also includes a drive shaft 12, which protrudes from the side of the cover body 11 facing the transmission cavity 2a. The first transmission member 3 has a transmission channel 3a, which is connected to the transmission cavity 2a. The drive shaft 12 is inserted into the transmission channel 3a to drive the first transmission member 3 to rotate.
[0054] For example, see Figure 2 The shape of the driving shaft 12 along the radial cross section can be an arc, and the angle corresponding to the arc can be a reflex angle greater than a straight angle and less than a circumferential angle.
[0055] For example, see Figure 7 The shape of the transmission channel 3a along the radial cross section can be an arc, and the angle corresponding to the arc can be a reflex angle greater than a straight angle and less than a circumferential angle.
[0056] In the embodiment of the present application, the drive shaft 12 is disposed in the transmission channel 3a to drive the first transmission member 3 to rotate, so that the connection between the drive shaft 12 and the first transmission member 3 is more convenient and has higher reliability.
[0057] In one embodiment, please refer to 6~ Fig. 9 The radial cross-section of the driving shaft 12 is an arc, the radial cross-section of the transmission channel 3 a is an arc, and the arc of the transmission channel 3 a is greater than the arc of the driving shaft 12 .
[0058] For example, Figure 7 and Fig. 9 The angle shown by R3 is the angle corresponding to the arc of the driving shaft 12, and the angle shown by R4 is the angle corresponding to the arc of the transmission channel 3a, and R4>R3.
[0059] In the embodiment of the present application, the curvature of the arc of the transmission channel 3a is greater than the curvature of the arc of the driving shaft 12, so that the driving shaft 12 has a rotational virtual position in the process of driving the first transmission member 3 to rotate. The rotation of the knob cover 1 in the rotational virtual position will not affect the winding or free release state of the winding device, which is beneficial to reduce the possibility of the winding device failing to tighten the wire due to accidental touch by the user.
[0060] It is understandable that the arc of the transmission channel 3a is not limited to being greater than the arc of the drive shaft 12. For example, the arc of the transmission channel 3a may also be equal to the arc of the drive shaft 12.
[0061] See also Figure 3The knob cover 1 of the present application further comprises a first bone position 13, a second bone position 14 and a third bone position 15, and the first bone position 13, the second bone position 14 and the third bone position 15 are all protruding from the side of the cover body 11 facing the transmission cavity 2a. Figure 6~Figure 9 When the first transmission member 3 is located at the first position, the first bone position 13 is disengaged from the end of the transmission ring 41 away from the transmission tooth 42 , and when the first transmission member 3 is located at the second position, the first bone position 13 abuts against the end of the transmission ring 41 away from the transmission tooth 42 .
[0062] In the embodiment of the present application, when the first transmission member 3 is located in the first position, the first bone position 13 is disengaged from the end of the transmission ring 41 away from the transmission tooth 42, and when the knob cover 1 drives the first transmission member 3 to rotate from the first position toward the second position, the first bone position 13 also rotates accordingly. When the first transmission member 3 is located in the second position, the first bone position 13 abuts against the end of the transmission ring 41 away from the transmission tooth 42, so that the first bone position 13 can directly constrain and limit the second transmission member 4, and then the torsional force of the knob cover 1 can directly act on the second transmission member 4 to drive the winding member 2 to rotate to wind and store the wire, which is beneficial to improving the stability and reliability of the knob cover 1 driving the winding member 2 to wind and reel in the wire.
[0063] It can be understood that the knob cover 1 is not limited to including the first bone position 13 .
[0064] See also Figure 6~Figure 9 When the first transmission member 3 is located in the first position, the second bone position 14 abuts against the transmission tooth 42, and the abutting surface of the second bone position 14 and the transmission tooth 42 is arranged cross-radially with the winding member 2. When the first transmission member 3 is located in the second position, the second bone position 14 disengages from the transmission tooth 42.
[0065] In the embodiment of the present application, in the process of the knob cover 1 driving the first transmission member 3 to rotate from the second position to the first position, the second bone position 14 disengaged from the transmission tooth 42 also rotates toward the transmission tooth 42 with the knob cover 1. When the first transmission member 3 is in the first position, the second bone position 14 and the transmission tooth 42 can fully abut against each other. The abutting surface of the second bone position 14 and the transmission tooth 42 is arranged radially cross-wise with the winding member 2, so that the second bone position 14 can squeeze the transmission tooth 42 out of the first rack 21 when it just starts to contact the transmission tooth 42 and continues to rotate, thereby facilitating the disengagement of the transmission tooth 42 from the first rack 21. Furthermore, when the first transmission member 3 is located in the first position and the knob cover 1 drives the first transmission member 3 to rotate in the direction away from the transmission tooth 42, the second bone position 14 abuts against the transmission tooth 42, so that the transmission rod 33 and the second bone position 14 jointly constrain the position of the second transmission member 4, so as to reduce the possibility of the transmission tooth 42 engaging with the first rack 21 when the winding member 2 is in a freely rotating line-releasing state, and can also assist the transmission tooth 42 to engage with the first rack 21 more smoothly when the first transmission member 3 rotates from the first position to the second position.
[0066] It can be understood that the knob cover 1 is not limited to including the second bone position 14 .
[0067] In one embodiment, please refer to Figure 2 The wire taking-up device further comprises a sounding member 5 and a wire storage bin 6. Figure 4~Figure 6 As shown, the wire storage bin 6 has a accommodating chamber 6a, the cover body 11 covers the opening of the accommodating chamber 6a, the cavity wall of the accommodating chamber 6a is formed with a second rack 61, the sounding member 5, the winding member 2, the first transmission member 3 and the second transmission member 4 are all arranged in the accommodating chamber 6a, one end of the sounding member 5 is connected to the first transmission member 3, and the other end of the sounding member 5 can abut against the second rack 61.
[0068] For example, see Figure 6 and Figure 8 One end of the sounding member 5 is connected to the transmission disk 32 , and the other end of the sounding member 5 can abut against the second rack 61 .
[0069] Exemplarily, one end of the sound-generating member 5 may also be connected to the transmission tooth 42 , and the other end of the sound-generating member 5 may abut against the second rack 61 .
[0070] Exemplarily, the material of the wire storage bin 6 may be plastic or metal.
[0071] Exemplarily, the sound-emitting member 5 may be made of plastic or metal.
[0072] In the embodiment of the present application, one end of the sound-emitting member 5 is connected to the first transmission member 3, so that the sound-emitting member 5 can rotate along with the first transmission member 3, and the other end of the sound-emitting member 5 can abut against the second rack 61, so that the sound-emitting member 5 can collide with the second rack 61 at intervals to make a sound during the process of rotating along with the first transmission member 3, which is beneficial to improving the user's experience of rotating the knob cover 1.
[0073] It can be understood that the wire taking-up device is not limited to including the sound-generating member 5 .
[0074] See also Figure 6 and Figure 8 When the first transmission member 3 is in the first position, the third bone position 15 abuts against the end of the sound-emitting member 5 away from the first transmission member 3, so that the end of the sound-emitting member 5 away from the first transmission member 3 is disengaged from the second rack 61; when the first transmission member 3 is in the second position, the third bone position 15 disengages from the end of the sound-emitting member 5 away from the first transmission member 3, so that the end of the sound-emitting member 5 away from the first transmission member 3 abuts against the second rack 61.
[0075] For example, see Figure 6When the first transmission member 3 is located at the first position, the third bone position 15 abuts against the end of the sounding member 5 away from the first transmission member 3, so that the end of the sounding member 5 away from the first transmission member 3 is separated from the second rack 61, and the knob cover 1 is rotated counterclockwise, and the third bone position 15 is synchronously rotated counterclockwise to keep the end of the sounding member 5 away from the first transmission member 3 separated from the second rack 61, so that when the knob cover 1 is rotated counterclockwise, the sounding member 5 will not collide with the second rack 61 to make a sound. When the first transmission member 3 is located at the first position and then the knob cover 1 is rotated clockwise, the rotational virtual position between the drive shaft 12 and the transmission channel 3a causes the third bone position 15 to be separated from the sounding member 5, and then the end of the sounding member 5 away from the first transmission member 3 can be abutted against the second rack 61 again under the action of its own elastic restoring force, so that when the knob cover 1 is rotated clockwise, the end of the sounding member 5 away from the first transmission member 3 can collide with the second rack 61 at intervals to make a sound.
[0076] In the embodiment of the present application, when the first transmission member 3 is located in the first position, the third bone position 15 is disengaged from the end of the sound-emitting member 5 away from the first transmission member 3, so that the end of the sound-emitting member 5 away from the first transmission member 3 is disengaged from the second rack 61, and then when the knob cover 1 is rotated from the second position toward the first position, the sound-emitting member 5 will not make a sound; when the first transmission member 3 is located in the second position, the third bone position 15 is disengaged from the end of the sound-emitting member 5 away from the first transmission member 3, so that the end of the sound-emitting member 5 away from the first transmission member 3 is abutted against the second rack 61, and then when the knob cover 1 is rotated from the first position toward the second position, the sound-emitting member 5 can make a sound. That is, when the knob cover 1 is rotated to put the wire-reeling device in a free rotation direction state, the sound-emitting part 5 of the knob cover 1 will not make a sound. When the knob cover 1 is rotated to put the wire-reeling device in a wire-reeling state, the sound-emitting part 5 of the knob cover 1 can make a sound, which makes it easy for the user to identify the state of the wire-reeling device by the sound and reduces the possibility of the user turning the knob cover 1 in the wrong direction.
[0077] In one embodiment, please refer to Figure 1 and Figure 2 The winding member 2 has a wire groove 2b and a wire threading hole, the wire groove 2b surrounds the outer peripheral side of the winding member 2, and the wire storage bin 6 has a wire outlet hole 6b, and the wire outlet hole 6b, the wire groove 2b and the wire threading hole are connected in sequence.
[0078] Exemplarily, there are two threading holes, and the wire can be passed through one of the threading holes and passed out of the other threading hole, so that the wire is wound in the wire groove 2b.
[0079] In the embodiment of the present application, the wire can be fixed in the threading hole and wound and stored inside the wire. When the wire is needed, the wire can be passed through the wire outlet hole 6b of the wire storage bin 6. The operation is relatively simple and reliable, and it is convenient for users to use.
[0080] In one embodiment, please refer to Figure 1 and Figure 2 The wire taking-up device includes a fixing seat 7 , and a wire storage bin 6 is arranged between the cover body 11 and the fixing seat 7 .
[0081] Exemplarily, the material of the fixing base 7 may be plastic or metal.

The fixing seat 7 can fix the wire taking-up device in more application scenarios to improve the applicability of the wire taking-up device of the present application.
