[0028] Compared with the prior art, the above technical solutions provided by the embodiments of the present application have the following advantages:

[0029] The cable take-up device provided in this application embodiment, during cable delivery, if the end of the cable away from the reel is subjected to external force, the portion of the cable housed in the housing rotates in a first direction. Under the action of the external force, the cable extends outwards, with the outward section becoming longer and the take-up section becoming shorter. During take-up, the reel rotates in the opposite direction of the first direction, causing the cable to rotate synchronously in the opposite direction under the winding force of the reel and quickly wind up onto the reel. This ensures that after the outward section of the cable is guided and turned by the guide section, the take-up section of the cable is wound onto the reel. During the cable winding process, the guide section remains in constant contact with the cable. Due to the first included angle between the lead-out and take-up sections, the housing restricts the movement direction of the lead-out section, and the reel restricts the movement direction of the take-up section. The guide section continuously applies pressure to the cable. Therefore, under the pressure of the guide section, the cable itself has tension. Under the winding force of the reel, the cable has a certain winding speed. Under the tension of the cable itself and the winding force of the reel, the cable connector tends to return to a state where the connector is not twisted relative to the cable, thus eventually returning to the correct position. This prevents the connection between the connector and the cable from being subjected to torque and cracking, ensuring the long-term reliability of the winding device. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0051] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0052] In related technologies, existing cable reeling devices can wind and recycle cables. However, due to limitations in appearance, the orientation of the cable connector in current cable reeling devices is usually not on the same line as the cable exit direction. After the cable is pulled out, it may twist. During the recycling process, the cable reeling device cannot adjust the cable winding direction, causing the connector to fail to return to the correct position. The connector twists relative to the cable, and the connection between the connector and the cable is prone to cracking due to torque.

[0053] Some cable reeling devices have a positioning structure, such as wrapping a magnet or iron block inside the connector. At the same time, a magnet also needs to be assembled or pasted at the corresponding position on the outer shell. The magnetic force of the magnet is used to attract the connector back to the correct position. This structure increases the design cost, and after repeated use, the magnet or iron block is easy to separate from the connector, causing the positioning function to fail.

[0054] To address the technical problem that existing take-up devices cannot return the cable connector to its initial state, and that the connection between the connector and the cable is prone to cracking due to torque, this application provides a take-up device in which, during the cable winding process, the connector returns to the correct position under the action of the cable's own tension and the winding force of the reel, thereby preventing the connection between the connector and the cable from cracking due to torque and ensuring the long-term reliability of the take-up device.

[0055] Figure 1 and Figure 2A cable winding device provided in this application includes a housing 1, a shell 2, a reel 3, and a guide 4. The shell 2 is disposed inside the housing 1. The reel 3 is used to wind up a cable 7 and is rotatably disposed inside the shell 2. The guide 4 is disposed on the shell 2 and is used to guide and divide the cable 7 into an exit segment 72 and a take-up segment 73. The exit segment 72 and the take-up segment 73 have a first included angle α, wherein the exit segment 72 extends outside the housing 1. During the winding process of the cable 7, the guide 4 is always pressed against the cable 7 so that the connector 71 of the cable 7 returns to the correct position under the action of the tension of the cable 7 itself and the winding force of the reel 3.

[0056] Understandably, during cable exit, if the end of cable 7 furthest from the reel 3 is subjected to external force, the portion of cable 7 housed in the housing 2 rotates in the first direction, causing the reel 3 to rotate simultaneously in the first direction. Under the action of external force, cable 7 extends outward, with the outward segment 72 of cable 7 becoming longer and the retracted segment 73 becoming shorter. During cable retraction, the reel 3 rotates in the opposite direction of the first direction, causing cable 7 to rotate synchronously in the opposite direction of the first direction under the retracting force of the reel 3, and quickly retract onto the reel 3. The outward segment 72 of cable 7 becomes shorter and the retracted segment 73 becomes longer, so that after the outward segment 72 of cable 7 is turned by the guide section 4, the retracted segment 73 of cable 7 is wound onto the reel 3. During the winding process of cable 7, the guide part 4 is always pressed against cable 7. Since there is a first included angle between the lead-out section 72 and the take-up section 73, and the housing 1 restricts the movement direction of the lead-out section 72 of cable 7, and the winding reel 3 restricts the movement direction of the take-up section 73 of cable 7, the guide part 4 can always provide pressure to cable 7. Therefore, cable 7 is in a taut state under the pressure of the guide part. Cable 7 itself has tension force. Cable 7 has a certain winding speed under the winding force of winding reel 3. Under the tension force of cable 7 itself and the winding force of winding reel 3, the connector 71 of cable 7 tends to return to the state where the connector 71 is not twisted relative to cable 7, and finally returns to the correct position. This correct position is the position where the connector 71 is not twisted relative to cable 7, thereby avoiding the connection between connector 71 and cable 7 from being torn by torque and ensuring the long-term reliability of the winding device. Compared to existing positioning structures that use magnets, the wire take-up device provided in this application does not require magnets, reducing costs, and still retains its positioning function after multiple uses.

[0057] Optionally, the first direction can be clockwise or counterclockwise. If the first direction is counterclockwise, then the opposite direction is clockwise.

[0058] It should be noted that there is a first included angle α between the outgoing section 72 and the receiving section 73. To avoid excessive bending stress caused by excessive bending of the cable 7, the first included angle α should not be set too small. Of course, the first included angle α should not be set too large, as this would weaken the tension of the guide part 4 on the cable 7. Specifically, the first included angle α can be set to 120°-170°. In this way, it can both avoid excessive bending stress caused by excessive bending of the cable 7 and provide appropriate tension of the guide part 4 on the cable 7. For example, the first included angle α can be set to 125°, 130°, 135°, 140°, 150°, 160°, etc.

[0059] Optionally, cable 7 can be any type of power cable, data cable, charging cable, headphone cable, audio cable, etc.

[0060] In one embodiment, such as Figure 3 and Figure 4 As shown, the housing 2 includes a first wall surface 201 and a second wall surface 202, which are disposed opposite to each other in the height direction of the housing 2. The guide part 4 includes a steering shaft 41, which is rotatably mounted on the housing 2. Specifically, the steering shaft 41 includes a first end and a second end disposed opposite to each other in its own axial direction. The first end of the steering shaft 41 is rotatably connected to the first wall surface 401, and / or the first end of the steering shaft 41 is rotatably connected to the second wall surface 402. That is to say, whether the first end of the steering shaft 41 is rotatably connected to the first wall surface 401 or the first end of the steering shaft 41 is rotatably connected to the second wall surface 402, a rotatable connection between the steering shaft 41 and the housing 2 can be achieved. When the cable is exiting, the take-up section 73 of the cable 7 is turned by the steering shaft 41 to form the exit section 72. When the cable is being taken out, the steering shaft 41 is always pressed against the cable 7 and can always provide pressure to the cable 7. Therefore, the cable 7 is in a taut state under the pressure of the guide part. The connector 71 of the cable 7 returns to the initial state under the tension of the cable 7 itself and the winding force of the reel 3. The initial state is that the connector 71 is not twisted relative to the cable 7, thereby avoiding the connection between the connector 71 and the cable 7 from being subjected to torque and cracking, and ensuring the long-term reliability of the take-up device.

[0061] The steering shaft 41 is rotatably mounted on the housing 2. When the cable is being extended or retracted, there is friction between the steering shaft 41 and the outer periphery of the cable 7. Under friction, the steering shaft 41 rotates around its own axis, thereby reducing the friction between the cable 7 and the steering shaft 41. At the same time, the steering shaft 41 is always in contact with the cable 7, which can prevent the cable 7 from directly contacting the housing 2, thereby reducing the friction between the cable 7 and the housing 2 and preventing wear on the outer layer of the cable 7 after long-term use.

[0062] In an embodiment not shown in the figure, the guide 4 includes a turning block disposed on the housing, and the turning block has a third channel for the cable 7 to pass through. When the cable is exiting, the take-up segment 73 of the cable 7 turns after passing through the third channel of the turning block to form the exit segment 72; when the cable is being taken up, the turning block is always pressed against the cable 7, and the turning block can always provide pressure to the cable 7. Therefore, the cable 7 is in a taut state under the pressure of the turning block, and the connector 71 of the cable 7 returns to the correct position under the tension of the cable 7 itself and the winding force of the reel 3. The correct position is that the connector 71 is not twisted relative to the cable 7, thereby avoiding the connection between the connector 71 and the cable 7 from being subjected to torque and cracking, and ensuring the long-term reliability of the take-up device.

[0063] In one embodiment, such as Figure 3 and Figure 4 As shown, a second outlet 221 is provided on the housing 2. Figure 2 As shown in the diagram, the second outlet 221 is used for the cable segment 72 to pass through, and the steering shaft 41 is disposed near the second outlet 221. The housing 2 includes a third wall surface 203 and a fourth wall surface 204, which are disposed opposite to each other in the width direction of the housing 2. The first wall surface 201, the third wall surface 203, the second wall surface 202, and the fourth wall surface 204 are sequentially arranged to form the second outlet 221. When the cable 7 is discharged, after being guided by the guide part 4, the cable segment 72 can extend out from the second outlet 221. The steering shaft 41 can be disposed in the internal space of the housing 2 (i.e., the first accommodating cavity described below). In order to facilitate the extension of the cable segment 72 from the second outlet 211, the steering shaft 41 is disposed near the second outlet 221, thereby avoiding interference of the cable segment 72 with the housing 2.

[0064] In another embodiment, such as Figure 4 As shown, the steering shaft 41 is located at the second outlet 221. The steering shaft 41 can be positioned close to the fourth wall surface 404. A first channel 42 is formed between the outer periphery of the steering shaft 41 and the third wall surface 403. The first channel 42 is used for the cable segment 72 to pass through. The size of the first channel 42 can be set to be slightly larger than the cross-sectional size of the cable 7 to prevent the cable 7 from directly contacting the wall surface of the housing 2 during the cable exiting or retracting process, thereby reducing the friction between the cable 7 and the housing 2 and preventing wear on the outer layer of the cable 7 after long-term use.

[0065] In another embodiment, such as Figure 4As shown, the steering shaft 41 is located at the second outlet 221. The steering shaft 41 can also be located close to the third wall 403. A second channel 43 is formed between the outer periphery of the steering shaft 41 and the fourth wall 403. The second channel 43 is used for the cable segment 72 to pass through. Similarly, the size of the second channel 43 can be set to be slightly larger than the cross-sectional size of the cable 7 to prevent the cable 7 from directly contacting the wall of the housing 2 during the cable exiting or retracting process, thereby reducing the friction between the cable 7 and the housing 2 and avoiding wear on the outer layer of the cable 7 after long-term use.

[0066] Optionally, such as Figure 3 As shown, the housing 2 is marked with an arrow, and the arrow indicates the first direction, that is, when the reel 3 rotates around the first direction, the cable 7 is in the outgoing state.

[0067] In one embodiment, such as Figure 5 and Figure 6 As shown, the housing 1 is provided with a first outlet 11 and a storage slot 12. The storage slot 12 is used to store the connector 71 of the cable 7. The first outlet 11 is connected to the storage slot 12, and the cable segment 72 extends from the first outlet 11 to the outside of the housing 1. It should be noted that the size of the first outlet 11 is configured to be smaller than the minimum size of the connector 71. For example, the end of the connector 71 near the first outlet 11 has a first height, and the first outlet 11 has a second height. The second height of the first outlet 11 is smaller than the first height of the connector 71. Therefore, the first outlet 11 can prevent the connector 71 of the cable 7 from entering the internal space of the housing 1 during the cable winding process.

[0068] Furthermore, such as Figure 6 As shown, the storage slot 12 has a fifth wall 121, which at least partially fits against the outer periphery of the connector 71 of the cable 7 to improve the stability of the connector 71 during storage. The fifth wall 121 can be flat or curved, depending on the shape of the connector 71. For example, if the connector is a cuboid, then the fifth wall 121 is correspondingly flat. Furthermore, the fifth wall 121 has a second included angle β with the horizontal direction. The size of the second included angle β is designed according to the aesthetics of the shape, while ensuring that the storage slot 71 has sufficient space to accommodate the connector 71 of the cable 7.

[0069] In one embodiment, such as Figure 5As shown, a guide groove 13 is provided on the housing 1, and the guide groove 13 is connected to the storage groove 12. Specifically, the guide groove 13 is located at the end of the storage groove 12 away from the first outlet 11. Optionally, the guide groove 13 has a guide slope, which forms a third angle with the horizontal direction. The third angle can be larger than the second angle or equal to the second angle. Preferably, the third angle is larger than the second angle to guide the connector 71 of the cable 7. During the cable winding process, the connector 71 is guided by the guide groove 13 and finally stored in the storage groove 12.

[0070] In another embodiment, such as Figure 6 As shown, the guide groove 13 has a guide surface 131, the slope of which gradually decreases along the direction close to the receiving groove 12, thereby guiding the connector 71 of the cable 7 during the cable winding process.

[0071] In this embodiment, during cable winding, the reel 3 rotates in the opposite direction to the first direction, causing the cable 7 to rotate synchronously in the opposite direction to the first direction and quickly wind up onto the reel 3. During the winding process of the cable 7, the guide groove 13 guides the cable 7 to gradually approach the receiving groove 12, and the guide part 4 always presses against the cable 7, so that the cable 7, under the action of the guide part 4, turns from the first outlet 11, passes through the second outlet 221, and is wound up onto the reel 3. Since the guide groove 13 plays a guiding role, the connector 71 of the cable 7 is received into the receiving groove 12 of the housing 1 under the action of the tension force of the cable 7 itself and the winding force of the reel 3, and returns to the correct position.

[0072] In one embodiment, such as Figures 7 to 9 As shown, the housing 2 includes a base 21 and a top cover 22. The top cover 22 is fitted onto the base 21, forming a first receiving cavity between the top cover 22 and the base 21. The cable reel 3 is disposed within the first receiving cavity. The cable reel 3 includes a fixed shaft 31, a first reel body 32, and a second reel body 33. The first reel body 32 and the second reel body 33 are arranged parallel to each other, and the two define a winding space for the cable 7. The first end of the fixed shaft 31 is connected to the first reel body 32, and the second end of the fixed shaft 31 passes through the second reel body 33 and is rotatably connected to the base 21. The end of the cable 7 away from the connector 71 is connected to the fixed shaft 31. During assembly, the cable reel 3 can be installed onto the base 21 first, and then the top cover 22 can be fitted onto the base 21 and fixed together with the base 21.

[0073] Optionally, the connection between the top cover 22 and the base 21 may include snap-fit ​​connection, fastener fixing connection, etc., and this application does not specifically limit this.

[0074] The specific manner in which the second end of the fixed shaft 31 is rotatably connected to the base 21 is not limited. For example, a shaft hole is provided on the base 21, and the second end of the fixed shaft 31 is rotatably connected to the shaft hole.

[0075] Optionally, such as Figure 8 As shown, the first wall surface 201 can be disposed on the inner wall surface of the base 21, and the second wall surface 202, the third wall surface 203, and the fourth wall surface 204 can be disposed on the inner wall surface of the top cover 22. When the steering shaft 41 is disposed at the second outlet 221, a first connecting hole can be disposed on the first wall surface 201, and the first connecting hole is rotatably connected to the steering shaft 41; a second connecting hole can be disposed on the second wall surface 202, and the second connecting hole is rotatably connected to the steering shaft 41.

[0076] The winding reel 3 can rotate relative to the housing 2 about a rotation axis, which is the central axis of the fixed shaft 31. For example... Figure 10 As shown, during cable exit, the portion of cable 7 stored in the winding space rotates in the first direction. Since the end of cable 7 away from connector 71 is fixedly connected to fixed shaft 31, it can drive the reel 3 to rotate relative to base 21 around the central axis of fixed shaft 31. Cable 7 extends out after passing through the second outlet 221 and the first outlet 11 in sequence. During cable retraction, reel 3 rotates in the opposite direction of the first direction, causing cable 7 to rotate synchronously in the opposite direction of the first direction and be wound up one turn at a time in the winding space of reel 3. During the winding process of cable 7, guide part 4 is always in contact with cable 7, so that cable 7, under the action of guide part 4, turns from the first outlet 11, passes through the second outlet 221, and is wound up in reel 3.

[0077] Optionally, a plurality of first receiving cavities may be formed between the top cover 22 and the base 21. For example, such as... Figure 8 As shown, two first accommodating cavities can be formed between the top cover 22 and the base 21. Therefore, the box body 1 can accommodate two winding reels 3, and two first outlets 11 are correspondingly provided on the box body 1. The top cover 22 can be provided with a second outlet 221.

[0078] In one embodiment, such as Figure 8 As shown, the take-up device includes a coil spring 5. The first end of the coil spring 5 is connected to the winding reel 3, and the second end of the coil spring 5 is connected to the housing 2. The coil spring 5 is a spiral spring. During the cable release process, the spiral spring undergoes elastic deformation to store elastic potential energy. When the outward pulling of the cable 7 stops, the winding reel 3 rotates in the opposite direction of the first direction under the elastic restoring force of the spiral spring, thereby winding up the cable 7.

[0079] Of course, in other embodiments, the coil spring 5 may also be a rotary motor, etc.

[0080] In one embodiment, such as Figure 8 and Figure 9As shown, the outer wall of the top cover 22 has a protrusion 222, which, together with the outer wall of the top cover 22, defines a second receiving cavity. The coil spring 5 is disposed within the second receiving cavity. The top cover 22 has a first engaging portion 223, and the first end of the coil spring 5 is connected to the first engaging portion 223. The side of the first disc 32 opposite to the second disc 33 has a second engaging portion 321, which is coaxially arranged with the fixed shaft 31. The engaging portion passes through the top cover 22 and is connected to the second end of the coil spring 5. The protrusion 222 can be configured as an annular baffle, which can limit the movement and prevent the coil spring 5 from shifting relative to the top cover 22 during operation. The first engaging portion 223 may include a engaging plate, and the first end of the coil spring 5 is fixedly connected to the engaging plate. The second engaging portion 321 may include a engaging shaft, on which a slot is formed, and the second end of the coil spring 5 is engaged with the slot.

[0081] When the cable 7 is pulled out, the portion of the cable 7 stored in the winding space rotates in the first direction. Since the end of the cable 7 away from the connector 71 is fixedly connected to the fixed shaft 31, it can drive the winding reel 3 to rotate relative to the base 21 around the central axis of the fixed shaft 31. The locking shaft rotates accordingly, causing the coil spring 5 to undergo elastic deformation during the cable pulling process, thereby storing elastic potential energy. When the cable 7 is stopped being pulled outward, the winding reel 3 rotates in the opposite direction of the first direction under the elastic restoring force of the spiral spring, thereby winding up the cable 7.

[0082] In one embodiment, such as Figure 11 and Figure 12 As shown, the first reel body 32 is provided with a first limiting part 322, a second limiting part 323, and a third limiting part 324 on the side opposite to the second reel body 33. The first limiting part 322, the second limiting part 323, and the third limiting part 324 are arranged sequentially from the center of the first reel body 32 outwards. A take-up groove 325 is formed between the first limiting part 322 and the second limiting part 323, and a take-out groove 326 is formed between the second limiting part 323 and the third limiting part 324. A stop member 6 is rotatably provided on the inner side wall of the top cover 22. The stop member 6 can swing relative to the winding reel 3 under the drive of the winding reel 3. A ball bearing 61 is provided on the stop member 6. The ball bearing 61 can slide on the take-up groove 325 or the take-out groove 326 so that the winding reel 3 has a take-up state or a take-out state.

[0083] The first limiting part 322 may include a first annular boss, the second limiting part 323 may include a second annular boss, and the third limiting part 324 may include a third annular boss. The first annular boss, the second annular boss, and the third annular boss are arranged sequentially along the radial direction of the first disc body 32. A take-up groove 325 is formed between the first annular boss and the second annular boss, and a take-out groove 326 is formed between the second annular boss and the third annular boss. The stop member 6 can swing relative to the winding reel 3 under the drive of the winding reel 3, so that the ball 61 can slide on the take-up groove 325 or the take-out groove 326. When the ball 61 slides on the take-up groove 325, the winding reel 3 is in the take-out state, and the cable 7 can extend outward; when the ball 61 slides on the take-out groove 326, the winding reel 3 is in the take-up state, and the cable 7 can be wound onto the winding reel 3.

[0084] The stop component 6 may include a lever, the first end of which is rotatably connected to the top cover 22 via a pivot, and the second end of which is provided with the ball bearing 61. The ball bearing 61 is slidably embedded in the take-up groove 325 or the take-out groove 326 relative to the protrusion 222 of the lever. The top cover 22 has a groove 224 on the side facing the reel 3 to accommodate the lever. The groove 224 can limit the ball bearing 61 in the rotation direction of the reel 3, preventing relative displacement between the ball bearing 61 and the housing 2 in the rotation direction of the reel 3. When the reel 3 is in the take-up or take-out state, the ball bearing 61 and the top cover 22 remain relatively fixed in the rotation direction of the reel 3. It should be noted that "relatively fixed" means that there is no relative displacement between the ball bearing 61 and the top cover 22 in the rotation direction of the reel 3. During the rotation of the reel 3 relative to the housing 2, the ball bearing 61 moves within the take-up groove 325 or the take-out groove 326.

[0085] Specifically, for ease of explanation and understanding, the first direction can be Figure 13 The direction R1 shown in the figure, the opposite direction of the first direction can be Figure 14 The R2 direction is shown in the diagram. Figure 13 As shown, when the reel 3 rotates along the first direction R1, the ball bearing 61 can move within the cable outlet groove 326, at which time the cable 7 is pulled outward, creating a cable outlet effect; as Figure 14 As shown, when the reel 3 rotates in the opposite direction R2 of the first direction, the ball bearing 61 can move within the take-up groove 325, at which time the cable 7 is rewound, forming a take-up effect.

[0086] In one embodiment, such as Figure 13As shown, the second limiting part 323 is provided with a first connecting groove 3231, which is connected to the cable outlet groove 326 and the cable take-up groove 325; the first disc body 32 is provided with a locking part 327 on the side opposite to the second disc body 33, and the locking part 327 is provided with a locking position 3271 that cooperates with the ball 61, and the locking position 3271 is recessed in the first connecting groove 3231.

[0087] When the ball bearing 61 moves to the locking position 3271, the reel 3 can no longer move in the opposite direction R2 of the first direction, thus forming a locking effect on the reel 3 in the winding direction, preventing the cable 7 from continuing to be wound back, and keeping the cable 7 at the corresponding length. Users can not only adjust the length of the cable 7 pulled out by controlling the rotation direction of the reel 3, but also make the cable 7 form a locking effect at various different lengths, which is convenient for users.

[0088] Specifically, in the locked state, such as Figure 13 As shown, when the ball bearing 61 is in the locking position 3271, as the reel 3 rotates along the first direction R1, the ball bearing 61 can continue to move from the locking position 3271 to the cable outlet groove 326. One rotation of the ball bearing 61 in the cable outlet groove 326 indicates that the cable 7 has been wound once. When the cable 7 is stopped from being pulled outwards, the reel 3 rotates in the opposite direction of the first direction under the elastic restoring force of the coil spring 5, causing the ball bearing 61 to enter the locking position 3271 from the first connecting groove 3231 under the action of the locking part 327, forming a locking effect. Therefore, after one stop, the cable 7 can be pulled outwards again and slowly released. With the cooperation of the reel 3, coil spring 5, stop part 6, and locking part 327, the rotation of the reel 3 in the opposite direction of the first direction is restricted, allowing for continued stopping while increasing the length of the cable 7. This achieves multi-stage stopping, allowing the cable 7 to be pulled out to multiple lengths, facilitating use in different scenarios. Furthermore, without retracting the cable, the length of cable 7 can be increased multiple times to maintain the stop position.

[0089] In one embodiment, such as Figure 14 As shown, the second limiting part 323 is provided with a second connecting groove 3232, which communicates with the cable outlet groove 326 and the cable take-up groove 325. The first connecting groove 3231 and the second connecting groove 3232 are respectively provided on both sides of the locking part 327. When the cable 7 is stopped from being pulled outward, the cable reel 3 rotates in the opposite direction R2 of the first direction under the elastic restoring force of the coil spring 5, and the ball bearing 61 can enter the cable take-up groove 325 from the second connecting groove 3232 to achieve the cable take-up effect.

[0090] like Figure 11As shown, the locking part 327 is provided with a first guide surface 3272. The first guide surface 3272 extends obliquely from the outlet groove 326 toward the take-up groove 325 in the opposite direction of the first direction, so as to guide the ball 61 from the outlet groove 326 through the second connecting groove 3232 and move to the take-up groove 325.

[0091] like Figure 11 As shown, a second guide surface 3273 is provided on the locking part 327. The second guide surface 3273 extends obliquely from the wire outlet groove 326 toward the locking position 3271 in the first direction, so as to guide the ball 61 from the wire outlet groove 326 to the locking position 3271 during the movement of the winding reel 3 in the first direction.
