The data line device of the present disclosure can wind the cable 300 through the rotating member 200, and the data line device of the present disclosure can also be referred to as a cable winder.

[0087] In some embodiments of the present disclosure, the data line device comprises a housing 100, a rotating member 200, a cable 300, a first elastic member 400, and a limiting assembly 500. The housing 100 has a containing space 101 and an opening 102 communicating with the containing space 101; the rotating member 200 is rotatably arranged in the containing space 101; a part of the cable 300 can be wound outside the rotating member 200 and can extend out of the housing 100 from the opening 102; the first elastic member 400 is arranged between the rotating member 200 and the housing 100 and is used to provide a force to the rotating member 200 to rotate in the receiving direction A; the limiting assembly 500 comprises a first limiting member 510, a second limiting member 520, and a third limiting member 530. The first limiting member 510 is arranged at one end of the rotating member 200; the periphery of the first limiting member 510 has at least one first groove 511; the second limiting member 520 is rotatable and arranged in the housing 100; the periphery of the second limiting member 520 has a first protruding part 521 for cooperating with the first groove 511; the end face 529 of the second limiting member further has a second protruding part 522 and a third protruding part 523 arranged at intervals; the third limiting member 530 is rotatably arranged in the housing 100 and located between the second protruding part 522 and the third protruding part 523; the periphery of the third limiting member 530 has at least one set of cooperating structures 531 for cooperating with the second protruding part 522 and the third protruding part 523; the second limiting member 520 is used to push the third limiting member 530 to rotate through the cooperating structures 531; the elastic assembly 600 is arranged between the second limiting member 520 and the housing 100; the elastic assembly 600 is used to provide a force to the second limiting member 520 to make the first protruding part 521 located in the first groove 511, so as to cooperate with the cooperating structures 531 to make the second limiting member 520 in the positioning state that the first protruding part 521 is located in the first groove 511.

[0088] The data line device of the present disclosure, since the part of the cable 300 can be coiled outside the rotating member 200 and can be stretched out of the housing 100 through the opening 102, when the cable 300 is pulled, the external force overcomes the deformation force of the first elastic member 400 and drives the rotating member 200 to rotate through the cable 300, the length of the cable 300 stretched out of the housing 100 increases, at this time, the first protruding part 521 is located outside the first groove 511, and the elastic assembly 600 is deformed; when the length of the cable 300 stretched out of the housing 100 meets the requirement, the cable 300 is no longer pulled, the first elastic member 400 can provide a force to the rotating member 200 to rotate in the storage direction, after the rotating member 200 drives the cable 300 to rotate a small amount in the storage direction, the deformation force of the elastic assembly 600 can make the second limiting member 520 rotate to the first protruding part 521 located in the first groove 511; the cooperation structure 531 can make the second limiting member 520 in the positioning state that the first protruding part 521 is located in the first groove 511 through cooperation with the second protruding part 522, so that the rotating member 200 can be prevented from driving the cable 300 to continue to rotate in the storage direction through the first protruding part 521.

[0089] In the related art, the data line device includes a housing, a rotating structure and a cable, the cable can be stored in the housing through the rotating structure and can be stretched out of the housing; when the cable of the data line storage structure is in a suitable use length, only one set of structure prevents the rotating structure from rotating in the winding direction, and the stability of the cable in the suitable length state is poor. If this set of structure fails due to manufacturing errors or wear and tear problems, this set of structure will not be able to prevent the rotating structure from rotating in the winding direction, and the cable of the data line storage structure will not be able to stably be in a suitable use length. The data line storage device of the present disclosure can reliably and stably be in a positioning state through the cooperation of the elastic assembly 600 and the cooperation structure 531, so that the cable 300 can reliably and stably be in a suitable use length.

[0090] In some embodiments of the present disclosure, in the stretched state, the elastic assembly 600 is used to provide a force to the second limiting member 520 to rotate in the first direction B, so that the first protruding part 521 is located in the first groove 511, and the cooperation structure 531 is used to make the second limiting member 520 in the positioning state that the first protruding part 521 is located in the first groove 511 through cooperation with the second protruding part 522.

[0091] When the cable 300 is pulled, the external force overcomes the deformation force of the first elastic member 400 and drives the rotating member 200 to rotate through the cable 300, and the length of the cable 300 extending out of the shell 100 increases, at this time, the first protruding part 521 is located outside the first groove 511, and the elastic assembly 600 is deformed; when the length of the cable 300 extending out of the shell 100 meets the requirement, the cable 300 is not pulled any more, the first elastic member 400 can provide a force to the rotating member 200 to rotate in the storage direction A, after the rotating member 200 drives the cable 300 to rotate a small amount in the storage direction A, the deformation force of the elastic assembly 600 can provide a force to the second limiting part 520 to rotate in the first direction B, so that the second limiting part 520 rotates to the state that the first protruding part 521 is located in the first groove 511, at the same time, the matching structure 531 can also drive the second limiting part 520 to be in the positioning state that the first protruding part 521 is located in the first groove 511 through cooperation with the second protruding part 522, so that the first protruding part 521 can prevent the rotating member 200 from driving the cable 300 to continue to rotate in the storage direction A, and the cable 300 can stably be in a suitable use length.

[0092] Of course, the deformation force of the elastic assembly 600 can also prevent the first protruding part 521 from being out of the first groove 511, thus, the second limiting part 520 can be more stably in the positioning state through the cooperation of the elastic assembly 600 and the matching structure 531, at this time, since the first protruding part 521 is located in the first groove 511, the first protruding part 521 can prevent the rotating member 200 from driving the cable 300 to continue to rotate in the storage direction, so that the cable 300 can be more stably in a suitable use length.

[0093] In some embodiments, the second protruding part 522 and the third protruding part 523 can have the same or similar height in the axial direction, since the second protruding part 522 and the third protruding part 523 on the second limiting part 520 cooperating with the third limiting part 530 have the same or similar height in the axial direction, at this time, the second limiting part 520 can be set to be thinner, so that the data line storage device can also be set to be thinner, thereby realizing the lightness and thinness of the data line storage device.

[0094] In the embodiments of the present disclosure, the data line device comprises a housing 100, a rotating member 200, a cable 300, a first elastic member 400 and a limiting assembly 500.

[0095] The data line device of the present disclosure, since the part of the cable 300 can be coiled outside the rotating member 200, and can be stretched out from the opening 102 to outside the shell 100, when pulling the cable 300, the external force overcomes the deformation force of the first elastic member 400 and drives the rotating member 200 to rotate through the cable 300, the length of the cable 300 stretched out of the shell 100 increases, at this time, the first protruding part 521 is located outside the first groove 511, and the elastic assembly 600 is deformed; when the length of the cable 300 stretched out of the shell 100 meets the requirement, the cable 300 is not pulled any more, the first elastic member 400 can provide a force to the rotating member 200 to rotate in the storage direction, after the rotating member 200 drives the cable 300 to rotate a small section in the storage direction, the deformation force of the elastic assembly 600 can make the second limiting member 520 rotate to the first protruding part 521 located in the first groove 511; the matching structure 531 can make the second limiting member 520 in the positioning state that the first protruding part 521 is located in the first groove 511 through cooperation with the second protruding part 522, at the same time, the deformation force of the elastic assembly 600 can also prevent the first protruding part 521 from coming out of the first groove 511, in this way, the second limiting member 520 can be more stably in the positioning state through the joint action of the elastic assembly 600 and the matching structure 531, at this time, since the first protruding part 521 is located in the first groove 511, the rotating member 200 can be prevented from driving the cable 300 to continue to rotate in the storage direction through the first protruding part 521, so that the cable 300 can be more stably in the appropriate use length.

[0096] In the related art, the data line device includes a shell, a rotating structure and a cable, the cable can be stored in the shell through the rotating structure, and can also be stretched out of the shell; when the cable of the data line storage structure is in the appropriate use length, only one set of structure can prevent the rotating structure from rotating in the winding direction, and the stability of the cable in the appropriate length state is poor, if the set of structure fails due to manufacturing errors or wear and tear problems, the set of structure will not be able to prevent the rotating structure from rotating in the winding direction, and the cable of the data line storage structure will not be able to be stably in the appropriate use length. The data line storage device of the present disclosure can make the data line device more reliably and stably in the positioning state through the joint action of the two sets of structure of the elastic assembly 600 and the matching structure 531, so that the cable 300 can be more reliably and stably in the appropriate use length.

[0097] In the embodiments of the present disclosure, the structure of the shell 100 is not limited. For example, the shell 100 can be a disc structure. For another example, the shell 100 can be a cuboid structure. As an example, as shown in FIG. 9, the shell 100 includes a first half shell 110 and a second half shell 120, the first half shell 110 and the second half shell 120 can be connected through a buckle structure, a threaded structure or the like, and a containing space 101 is defined between the first half shell 110 and the second half shell 120. Here, the shell 100 can have one opening 102, or can have two openings 102.

[0098] In the embodiments of the present disclosure, the structure of the rotating member 200 is not limited. For example, the rotating member 200 can be a columnar structure. The implementation manner in which the rotating member 200 is rotatably arranged in the containing space 101 is not limited. For example, the rotating member 200 can be rotatably arranged in the containing space 101 through a rotating shaft structure. As an example, a first connecting column 140 is arranged in the containing space 101, the rotating member 200 has a fourth connecting hole 230, the first connecting column 140 is arranged in the fourth connecting hole 230 and can rotate in the fourth connecting hole 230; thus, the rotating member 200 is rotatably arranged in the containing space 101 by arranging the first connecting column 140 in the fourth connecting hole 230. Here, as shown in FIG. 8, the first connecting column 140 can be fixed to the second half shell 120, of course, the first connecting column 140 and the second half shell 120 can also be a structural member; the first connecting column 140 can also be connected with the first half shell 110, for example, as shown in FIG. 7, the first half shell 110 has a first connecting hole 133, as shown in FIG. 9 and FIG. 10, a connecting member 810 is connected with the first connecting column 140 through the first connecting hole 133, the connecting member 810 can be a screw, and a threaded hole can be arranged on the first connecting column 140. In an application, the first connecting column 140 and the second half shell 120 are a structural member.

[0099] In the embodiments of the present disclosure, the cable 300 can be stretched at one end to increase the length of the cable 300, or can be stretched at two ends to increase the length of the cable 300. As an example, as shown in FIG. 10, the shell 100 has one opening 102, and as shown in FIG. 1, the first end of the cable 300 can be provided with a first interface 710, which can be a USB type interface or a type-c interface, and the first interface 710 is located outside the shell 100 for interface plugging with an external electronic device. The second end of the cable 300 is located in the accommodation space 101, and the second end of the cable 300 is electrically connected to the second interface 720 provided on the surface of the shell 100 through the connecting wire 730. Here, a circuit board can also be provided between the second interface 720 and the connecting wire 730 to ensure that the second interface 720 and the cable 300 are always electrically connected during the rotation of the cable 300 relative to the shell 100. Of course, in other implementations, the shell 100 can also have two openings 102, and the two ends of the cable 300 can respectively extend out of the shell 100 through the two openings 102 to adjust the length of the cable 300 by stretching the two ends of the cable 300.

[0100] In the embodiments of the present disclosure, the structure of the first elastic member 400 is not limited, and the first elastic member 400 can provide a force to the rotating member 200 to rotate in the accommodation direction A. For example, as shown in FIG. 13, the first elastic member 400 can be a torsion spring. The first end of the first elastic member 400 is connected to the shell 100, and the second end of the first elastic member 400 is connected to the rotating member 200. During the stretching of the cable 300, the cable 300 drives the rotating member 200 to rotate, and the first elastic member 400 deforms. The first elastic member 400 can provide a force to the rotating member 200 to rotate in the accommodation direction A through the restoring force of deformation. As an example, as shown in FIG. 8, the first connecting column 140 is provided with a first clamping groove 141, and the first end of the first elastic member 400 is clamped in the first clamping groove 141 to fix the first end of the first elastic member 400 to the shell 100. As another example, as shown in FIG. 14, the rotating member 200 has an adjacent winding portion 210 and baffle portion 220 in the axial direction. The first elastic member 400 is arranged between the winding portion 210 and the shell 100. As shown in FIG. 13, the winding portion 210 can have a ring structure, and part of the first elastic member 400 is wound in the cavity of the winding portion 210. The wall of the winding portion 210 has a second clamping groove 211, and the second end of the first elastic member 400 is clamped in the second clamping groove 211 to fix the second end of the first elastic member 400 to the winding portion 210 of the rotating member 200. Here, part of the cable 300 can be wound outside the winding portion 210 and can extend out of the shell 100 from the opening 102.

[0101] In the embodiments of the present disclosure, the limiting assembly 500 comprises a first limiting piece 510, a second limiting piece 520, a third limiting piece 530, and an elastic assembly 600. Through cooperation of the first limiting piece 510, the second limiting piece 520, the third limiting piece 530, and the elastic assembly 600, the rotating piece 200 can be positioned relative to the shell 100, so that the cable 300 can be stably at a suitable length for use.

[0102] The structure of the first limiting piece 510 is not limited. For example, the first limiting piece 510 can be a plate structure. As an example, as shown in FIG. 1, the first limiting piece 510 can be a disc structure. When the rotating piece 200 comprises the winding part 210 and the baffle part 220, the first limiting piece 510 can be arranged at one end of the baffle part 220 facing away from the winding part 210, so as to separate the winding part 210 and the first limiting piece 510 through the baffle part 220, that is, separate the cable 300 and the limiting assembly 500, to prevent the cable 300 and the limiting assembly 500 from affecting each other. Here, as shown in FIG. 14, the first limiting piece 510 and the rotating piece 200 can be different parts of the same structural piece, so as to facilitate processing and manufacturing, and improve the connection strength of the first limiting piece 510 and the baffle part 220. Of course, the first limiting piece 510 and the rotating piece 200 can also be different structural pieces, and in this case, the first limiting piece 510 and the rotating piece 200 can be connected through bonding, welding, threaded structure, etc.

[0103] The number of the first grooves 511 on the circumferential side of the first limiting piece 510 is not limited. As an example, as shown in FIGS. 1 to 4, four first grooves 511 are uniformly arranged on the circumferential side of the first limiting piece 510 in the circumferential direction.

[0104] The second limiting piece 520 can be rotatably arranged on the shell 100 through a rotating shaft structure. For example, as shown in FIG. 7, the first half shell 110 has a third connecting column 135, and as shown in FIG. 11, the second limiting piece 520 has a third connecting hole 528, the third connecting column 135 is inserted into the third connecting hole 528 and can rotate in the third connecting hole 528, so as to realize rotatable arrangement of the second limiting piece 520 on the shell 100 through insertion of the third connecting column 135 into the third connecting hole 528. Of course, in other implementation manners, the third connecting column 135 can also be arranged on the second limiting piece 520, and the third connecting hole 528 can also be arranged on the shell 100.

[0105] The circumferential side of the second limiting member 520 has a first protruding part 521 for cooperating with the first groove 511; when the rotating member 200 is rotated to a first groove 511 facing the second limiting member 520, the second limiting member 520 can be rotated to the first protruding part 521 being located in the first groove 511, so as to connect the second limiting member 520 and the rotating member 200, thereby the second limiting member 520 can prevent the rotating member 200 from rotating or the rotating member 200 can drive the second limiting member 520 to rotate by the first protruding part 521 being located in the first groove 511. Of course, the second limiting member 520 can also be rotated to the first protruding part 521 being located out of the first groove 511, so as to separate the second limiting member 520 and the rotating member 200.

[0106] As shown in FIG. 1 and FIG. 2, the end surface 529 of the second limiting member also has a second protruding part 522 and a third protruding part 523 arranged at intervals; the axial heights of the second protruding part 522 and the third protruding part 523 can be the same or close. Of course, the axial heights of the second protruding part 522 and the third protruding part 523 can also be different. The end surface 529 of the second limiting member refers to the surface perpendicular to the axis of the second limiting member 520. The cross-sectional shape of the second protruding part 522 and the third protruding part 523 is not limited. For example, the cross section of the second protruding part 522 can be oval, and the cross section of the third protruding part 523 can be similar to a triangle.

[0107] The third limiting member 530 can be rotatably arranged in the shell 100 through a rotating shaft structure. For example, as shown in FIG. 7, the first half shell 110 has a second connecting column 134, and as shown in FIG. 12, the third limiting member 530 has a second connecting hole 532, the second connecting column 134 is inserted into the second connecting hole 532 and can rotate in the second connecting hole 532, so as to realize that the third limiting member 530 is rotatably arranged in the shell 100 by the second connecting column 134 being inserted into the second connecting hole 532. Of course, in other implementation manners, the second connecting column 134 can also be arranged in the third limiting member 530, and the second connecting hole 532 can also be arranged in the shell 100.

[0108] The axis of the third limiting member 530 and the axis of the second limiting member 520 can be parallel, so that the second limiting member 520 can push the third limiting member 530 to rotate smoothly through the matching structure 531. Here, the end face of the third limiting member 530 and the end face 529 of the second limiting member can be arranged adjacent to each other, at this time, there is no other structural member between the end face of the third limiting member 530 and the end face 529 of the second limiting member, and the gap between the end face of the third limiting member 530 and the end face 529 of the second limiting member can be set smaller, thereby reducing the setting space of the limiting assembly 500. As an example, the third limiting member 530 and the second protruding portion 522 have the same or close height in the axial direction, that is, the third limiting member 530 can be arranged in the space defined by the second protruding portion 522 and the third protruding portion 523, at this time, the third limiting member 530 does not need to be provided with a separate setting space in the housing 100, thereby achieving the thinness of the data line storage device. Here, the end face of the third limiting member 530 refers to the surface of the third limiting member 530 perpendicular to the axis of the third limiting member 530.

[0109] The third limiting member 530 is located between the second protruding portion 522 and the third protruding portion 523; the peripheral side of the third limiting member 530 has at least one set of matching structures 531 for cooperating with the second protruding portion 522 and the third protruding portion 523; the second limiting member 520 is used to push the third limiting member 530 to rotate through the matching structure 531, so that different regions of the matching structure 531 cooperate with the second protruding portion 522 and the third protruding portion 523, thereby making the data line storage device in different states.

[0110] The form of the matching structure 531 is not limited, and the matching structure 531 can make the second limiting member 520 in a positioning state in which the first protruding portion 521 is located in the first groove 511 by cooperating with the second protruding portion 522. As an example, the axial thickness of the third limiting member 530 is uniformly arranged, and the matching structure 531 is arranged along the circumference of the third limiting member 530. Since the matching structure 531 is arranged along the circumference of the third limiting member 530, the axial thickness of the third limiting member 530 can be arranged more uniformly, thereby achieving the thinness of the third limiting member 530 in the axial direction. Of course, in other examples, the axial thickness of the third limiting member 530 can also be arranged non-uniformly, at this time, part of the matching structure 531 can be arranged along the circumference of the third limiting member 530, and the remaining part of the matching structure 531 can be arranged along the axial direction of the third limiting member 530.

[0111] The number of matching structures 531 is not limited. For example, as shown in FIG. 12, the third limiting member 530 has three sets of matching structures 531, which are uniformly distributed along the circumference of the third limiting member 530.

[0112] In the embodiments of the present disclosure, the structure of the elastic assembly 600 is not limited. The elastic assembly 600 can be used to provide a bidirectional rotating force to the second limiting piece 520, or can be used to provide a unidirectional rotating force to the second limiting piece 520. For example, in the stretched state, the elastic assembly 600 is used to provide a rotating force in the first direction B to the second limiting piece 520, so that the first protruding part 521 is located in the first groove 511.

[0113] As an example, the structure of the elastic assembly 600 is not limited, and in the stretched state, the elastic assembly 600 is used to provide a rotating force in the first direction B to the second limiting piece 520, so that the first protruding part 521 is located in the first groove 511. For example, the elastic assembly 600 can include a spring, a first end of the spring can be fixed to the shell 100, and a second end of the spring can be in contact with the second limiting piece 520; in the stretched state, the spring is in a deformed state, and the spring is used to provide a rotating force in the first direction B to the second limiting piece 520 through the deformation force, so that the first protruding part 521 is located in the first groove 511.

[0114] As another example, the structure of the elastic assembly 600 is not limited, and the elastic assembly 600 is used to provide a bidirectional rotating force to the second limiting piece 520 to make the first protruding part 521 located in the first groove 511, so as to cooperate with the matching structure 531 to make the second limiting piece 520 in the positioning state in which the first protruding part 521 is located in the first groove 511. Here, in the stretched state, the elastic assembly 600 is used to provide a rotating force in the first direction B to the second limiting piece 520, so that the first protruding part 521 is located in the first groove 511; in the positioning state, the elastic assembly 600 is used to provide a rotating force in the second direction A to the second limiting piece 520, so as to prevent the first protruding part 521 from being pulled out of the first groove 511, thereby making the data line device stably in the positioning state.

[0115] For example, the elastic assembly 600 can include two springs, first ends of the two springs can be fixed to the shell 100, and second ends of the two springs can be in contact with two opposite sides of the second limiting piece 520; in the stretched state, one spring is in a deformed state, and the one spring is used to provide a rotating force in the first direction B to the second limiting piece 520 through the deformation force, so that the first protruding part 521 is located in the first groove 511, and in the positioning state, the other spring is in a deformed state, and the other spring is used to provide a rotating force in the second direction A to the second limiting piece 520 through the deformation force, so as to prevent the first protruding part 521 from being pulled out of the first groove 511.

[0116] For example, the elastic assembly 600 can include a torsion spring, which can be sleeved on the rotating shaft structure between the second limiting member 520 and the shell 100. When the first protruding part 521 is on the side of the first limiting member, the torsion spring is in a natural state, i.e., the torsion spring is not deformed. In the stretched state, the first protruding part 521 is deflected, and the torsion spring is deformed, which is used to provide a force for rotating the second limiting member 520 in the first direction B, so that the first protruding part 521 is located in the first groove 511. In the positioning state, the first protruding part 521 is deflected, and the torsion spring is deformed, which is used to provide a force for rotating the second limiting member 520 in the second direction A, so that the first protruding part 521 is prevented from being separated from the first groove 511, thereby stably keeping the data line device in the positioning state.

[0117] In some implementations of the embodiments of the present disclosure, the matching structure 531 can include a first matching part 1302, a second matching part 1303 and a third matching part 1301 which are arranged adjacent to each other in the circumferential direction of the third limiting member 530. The first matching part 1302 and the third matching part 1301 are used to match with the second protruding part 522. The second matching part 1303 is used to match with the third protruding part 523. The distance between the first matching part 1302 and the axis is less than the distance between the third matching part 1301 and the axis. In the stretched state, the second matching part 1303 matches with the third protruding part 523. In the positioning state, the second protruding part 522 contacts the third matching part 1301. In the storage state, the second protruding part 522 matches with the first matching part 1302, so that when the data line storage device switches between two adjacent states, the second limiting member 520 can push the third limiting member 530 to rotate through the matching structure 531, so that in the next state, the different positions of the second limiting member 520 and the third limiting member 530 match, thereby making the second limiting member 520 present different states.

[0118] In the present implementation, the specific structure of the first matching part 1302, the second matching part 1303 and the third matching part 1301 is not limited.

[0119] For example, as shown in FIGS. 1-4, the first fitting part 1302 includes a second groove 5311, the second fitting part 1303 includes a first side surface 5312, and the third fitting part 1301 includes a third groove 5313; the second groove 5311 and the third groove 5313 are used to cooperate with the second protruding part 522; the first side surface 5312 is used to cooperate with the second side surface of the third protruding part 523; wherein the depth of the second groove 5311 is greater than the depth of the third groove 5313, that is, the distance between the second groove 5311 and the axis is less than the distance between the third groove 5313 and the axis; in the stretching state, the first side surface 5312 and the second side surface are adjacently arranged; in the positioning state, the second protruding part 522 is located in the third groove 5313; in the storage state, the second protruding part 522 is located in the second groove 5311.

[0120] The third protruding part 523 is also used to cooperate with the third groove 5313 (the third fitting part 1301) to push the third limiting part 530 to rotate.

[0121] In use, as shown in FIG. 4, in the stretched state, an external force overcomes the deformation force of the first elastic member 400 to pull the cable 300, the cable 300 drives the rotating member 200 to rotate along the stretching direction B, and the length of the cable 300 increases, at this time, the first protruding part 521 is located outside the first groove 511, when the cable 300 is pulled to a suitable length, the external force is removed, the rotating member 200 rotates to the storage direction A under the action of the deformation force of the first elastic member 400, when the rotating member 200 rotates to the side of the first groove 511 facing the second limiting member 520, the elastic assembly 600 drives the first protruding part 521 to be located in the first groove 511 by providing a force along the first direction B to the second limiting member 520, at the same time, in the stretched state, the second limiting member 520 also drives the third limiting member 530 to rotate due to the adjacent arrangement of the first side surface 5312 and the second side surface, when the second limiting member 520 rotates to the second protruding part 522 being located in the third groove 5313, as shown in FIG. 2, the third limiting member 530 prevents the second limiting member 520 from rotating, and at this time, the resistance of the first protruding part 521 to the rotating member 200 is greater than the force provided by the first elastic member 400 to the rotating member 200 in the storage direction A, so that the second limiting member 520 is in the positioning state of the first protruding part 521 being located in the first groove 511, to ensure that the cable 300 is stably at a suitable length, when it is needed to store the cable 300 in the shell 100, the cable 300 can be pulled again by an external force, the cable 300 drives the rotating member 200 to rotate along the stretching direction B, so that the first protruding part 521 is out of the first groove 511, at the same time, the third protruding part 523 drives the third limiting member 530 to rotate to the position where the second protruding part 522 corresponds to the second groove 5311 due to the cooperation with the third groove 5313 (the third matching part 1301), when the external force is removed, the first protruding part 521 is located in the first groove 511 again, and the second limiting member 520 is driven by the first protruding part 521 to rotate along the first direction B by a certain angle, when the second limiting member 520 rotates to the second protruding part 522 being located in the second groove 5311, since the depth of the second groove 5311 is greater than the depth of the third groove 5313, the first protruding part 521 is located outside the first groove 511, as shown in FIG. 3, at this time, the second limiting member 520 cannot prevent the rotating member 200 from rotating by the first protruding part 521, the rotating member 200 rotates along the storage direction A under the action of the first elastic member 400 until the part of the cable 300 that can be wound outside the rotating member 200 is all wound outside the rotating member 200.When the length of the cable 300 needs to be adjusted, the cable 300 can be pulled by an external force to overcome the deformation force of the first elastic member 400, and the rotating member 200 is driven to rotate in the stretching direction B. When the rotating member 200 rotates to the first groove 511 facing the second limiting member 520, the first protruding part 521 enters the first groove 511, and the rotating member 200 can drive the second limiting member 520 to rotate in the second direction A through the first protruding part 521. At the same time, since the second protruding part 522 is located in the second groove 5311, the second limiting member 520 can drive the third limiting member 530 to rotate by a certain angle. When the rotating member 200 drives the second limiting member 520 to rotate in the second direction A through the first protruding part 521, the first protruding part 521 is located outside the first groove 511, and the data line storage device is in the stretching state again, as shown in FIG. 4. At this time, the first side surface 5312 and the second side surface are adjacent. The data line storage device can repeatedly switch between the stretching state, the positioning state and the storage state in the use process, so as to facilitate the use of the data line storage device. Of course, in other forms of use process, the data line storage device can be in the storage state for a short time. At this time, the user can adjust the length of the cable 300 by repeatedly switching the data line storage device between the stretching state, the positioning state and the storage state. That is, the data line storage device is in the storage state in order to enter the stretching state and the positioning state again, and is not for storing the cable 300 in the shell 100.

[0122] Among them, the second direction A and the first direction B are opposite, the stretching direction B and the storage direction A are opposite, and the second direction A and the storage direction A are the same. For example, the stretching direction B is the clockwise direction, the first direction B is the clockwise direction, the storage direction A is the counterclockwise direction, and the second direction A is the counterclockwise direction.

[0123] In the use process, when the data line storage device switches between adjacent states, the second limiting member 520 can drive the third limiting member 530 to rotate by a certain angle through the matching structure 531, so that the first protruding part 521 of the second limiting member 520 and the first groove 511 are in different relative positional relationships when entering the next state.

[0124] In the present example, as shown in FIGS. 1 and 12, the third limiting member 530 further has a protruding structure between the second groove 5311 and the third groove 5313 on the side thereof, and the first side surface 5312 can be located on the side of the protruding structure facing the second groove 5311.

[0125] In the present example, as shown in FIG. 3, the shape of the insertion end of the second protruding part 522 matches the shape of the second groove 5311, and the end surface of the insertion end of the second protruding part 522 is used to contact the bottom surface of the second groove 5311, so that the insertion end of the second protruding part 522 can be completely inserted into the second groove 5311, thereby making the data line storage device stably in the storage state. Of course, in other implementations, the side surface of the insertion end of the second protruding part 522 can be used to contact the side surface of the second groove 5311.

[0126] As shown in FIG. 2, the end surface of the insertion end of the second protruding part 522 is used to contact the side surface of the third groove 5313, so that the data line storage device stably in the positioning state. Of course, in other implementations, the end surface of the insertion end of the second protruding part 522 can be used to contact the bottom surface of the second groove 5311. As an example, as shown in FIG. 11, the first included angle C1 between the two side surfaces of the insertion end of the second protruding part 522 is less than 45 degrees, and as shown in FIG. 12, the second included angle C2 between the two side surfaces of the third groove 5313 is greater than 90 degrees, so that the end surface of the insertion end of the second protruding part 522 can contact the side surface of the third groove 5313. Here, the value of the first included angle C1 is not limited. For example, the first included angle C1 can range from 39 degrees to 41 degrees; the value of the second included angle C2 is not limited. For example, the second included angle C2 can range from 100 degrees to 105 degrees. As shown in FIG. 12, the third included angle C3 between the two side surfaces of the second groove 5311 can range from 40 degrees to 42 degrees, so that the insertion end of the second protruding part 522 is inserted into the second groove 5311, and the end surface of the insertion end of the second protruding part 522 is used to contact the bottom surface of the second groove 5311.

[0127] Of course, in other examples, the first cooperating part 1302, the second cooperating part 1303, and the third cooperating part 1301 can also have other structural forms. As an example, the first cooperating part 1302, the second cooperating part 1303, and the third cooperating part 1301 can all be groove structures, or some of the first cooperating part 1302, the second cooperating part 1303, and the third cooperating part 1301 are groove structures, and the remaining part of the first cooperating part 1302, the second cooperating part 1303, and the third cooperating part 1301 are planar structures, and here, in the stretched state, the second cooperating part 1303 cooperates with the third protruding part 523; in the positioning state, the second protruding part 522 contacts the third cooperating part 1301; in the storage state, the second protruding part 522 cooperates with the first cooperating part 1302, so that when the two states are switched, the second limiting part 520 can push the third limiting part 530 to rotate.

[0128] In some implementations of the embodiments of the present disclosure, as shown in FIG. 11, the second limiting member 520 can include a first structure part 526 and a second structure part 527. The first structure part 526 is rotatably connected with the shell 100, and the elastic assembly 600 is arranged between the first structure part 526 and the shell 100, so that the elastic assembly 600 provides a force in the first direction B to the second limiting member 520 through the first structure part 526. The first side of the second structure part 527 is connected with the first structure part 526, and the second side of the second structure part 527 has the first protruding part 521, the second protruding part 522, and the third protruding part 523 located on the end face 5271 of the second structure part.

[0129] In the present implementation, the end face 5271 of the second structure part refers to the surface of the second structure part 527 perpendicular to the axis of the second limiting member 520.

[0130] In the present implementation, the rotatable connection between the first structure part 526 and the shell 100 is similar to the rotatable connection between the second limiting member 520 and the shell 100 described above, and will not be repeated here. As an example, as shown in FIG. 11, the third connecting hole 528 is arranged on the first structure part 526. The arrangement of the elastic assembly 600 between the first structure part 526 and the shell 100 is similar to the arrangement of the elastic assembly 600 between the second limiting member 520 and the shell 100 described above, and will not be repeated here.

[0131] In the present implementation, the first part 5261 of the first structure part protrudes in the axial direction beyond the end face 5271 of the second structure part, and the third limiting member 530 is located in the space defined by the first part 5261 of the first structure part, the second protruding part 522, and the third protruding part 523; thereby reducing the axial arrangement space of the third limiting member 530; at the same time, since the first part 5261 of the first structure part protrudes in the axial direction beyond the end face 5271 of the second structure part, that is, the first part 5261 of the first structure part, the second protruding part 522, and the third protruding part 523 are on the same side of the second limiting member 520, which can not only increase the axial size of the first structure part 526 to improve the cooperation strength between the first structure part 526 and the elastic assembly 600, but also reduce the overall axial size of the second limiting member 520.

[0132] In the present implementation, the axial height of the second protruding part 522 and the first part 5261 of the first structure part is the same or close, that is, the first part 5261 of the first structure part does not increase the overall axial size of the second limiting member 520, thereby realizing the smallest possible axial size of the second limiting member 520 to realize the thinness of the data line storage device.

[0133] In some implementations of the embodiments of the present disclosure, the data line storage device can further have a storage state; in the stretched state, the elastic assembly 600 provides a force to the second limiting piece 520 in the first direction B, and the first protruding part 521 is located outside the first groove 511; in the storage state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, and the first protruding part 521 is located outside the first groove 511; in the positioning state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, and the first protruding part 521 is located inside the first groove 511; wherein the second direction A and the first direction B are opposite.

[0134] In the present implementation, as shown in FIG. 2, in the positioning state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, so that the deformation force of the elastic assembly 600 can prevent the second limiting piece 520 from rotating in the first direction B, at this time, both the elastic assembly 600 and the matching structure 531 are used to prevent the second limiting piece 520 from rotating in the first direction B, so that the first protruding part 521 can be more stably located inside the first groove 511, to prevent the rotating piece 200 from rotating in the storage direction A. Of course, in other implementations, in the positioning state, the elastic assembly 600 can also not provide a force to the second limiting piece 520 in the second direction A, at this time, the matching structure 531 is used to prevent the second limiting piece 520 from rotating in the first direction B.

[0135] In the present implementation, as shown in FIG. 3, in the storage state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, so that when switching from the storage state to the stretched state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, so that the first protruding part 521 can quickly enter the first groove 511. Of course, in other implementations, in the storage state, the elastic assembly 600 can also not provide a force to the second limiting piece 520 in the second direction A.

[0136] As an example, in the stretched state, the elastic assembly 600 provides a force to the second limiting piece 520 in the first direction B, and the first protruding part 521 is located outside the first groove 511; in the storage state, the elastic assembly 600 provides a force to the second limiting piece 520 in the second direction A, and the first protruding part 521 is located outside the first groove 511; in the positioning state, the elastic assembly 600 does not provide a force to the second limiting piece 520 in the second direction A, and the first protruding part 521 is located inside the first groove 511.

[0137] In the present implementation, the structure of the elastic assembly 600 is not limited, in the stretched state, the elastic assembly 600 is configured to provide the second limiting member 520 with a force for rotating in the first direction B, in the storage state, the elastic assembly 600 is configured to provide the second limiting member 520 with a force for rotating in the second direction A, and in the positioning state, the elastic assembly 600 can provide the second limiting member 520 with a force for rotating in the second direction A.

[0138] For example, the elastic assembly 600 can include a third elastic member 620 and a second elastic member 610. The third elastic member 620 is configured to provide the second limiting member 520 with a force for rotating in the first direction B, and the second elastic member 610 is configured to provide the second limiting member 520 with a force for rotating in the second direction A.

[0139] In the present example, the structure of the third elastic member 620 and the second elastic member 610 is not limited. For example, the third elastic member 620 and the second elastic member 610 can each be a sheet-shaped structure, and the third elastic member 620 and the second elastic member 610 can be located on opposite sides of the second limiting member 520. For another example, the third elastic member 620 and the second elastic member 610 can each be a torsion spring structure, and the third elastic member 620 and the second elastic member 610 can each be arranged on the rotation shaft structure of the second limiting member 520 and the housing 100. As an example, the third elastic member 620 and the second elastic member 610 can be torsion spring structures arranged on the third connecting column 135.

[0140] For another example, the second elastic member 610 and the third elastic member 620 are arranged on the housing 100, and the second elastic member 610 and the third elastic member 620 are located on opposite sides of the second limiting member 520 and are configured to respectively contact the second limiting member 520.

[0141] Here, the second elastic member 610 and the third elastic member 620 can each be a strip-shaped structure. Of course, the second elastic member 610 and the third elastic member 620 can also be sheet-shaped structures.

[0142] Here, as shown in FIG. 1, a first end of the second elastic member 610 is connected to the housing 100, and a second end of the second elastic member 610 is configured to contact the second limiting member 520; a first end of the third elastic member 620 is connected to the housing 100, and a second end of the third elastic member 620 is configured to contact the second limiting member 520.

[0143] Here, as shown in FIGS. 5 and 6, the second limiting member 520 is provided with a first recessed portion 524 and a second recessed portion 525 arranged oppositely on the peripheral side; the second end of the second elastic member 610 can be located in the first recessed portion 524, and the second end of the third elastic member 620 can be located in the second recessed portion 525, so as to ensure that the second end of the second elastic member 610 is always in contact with the second limiting member 520, and the second end of the third elastic member 620 is always in contact with the second limiting member 520, preventing the second elastic member 610 and the third elastic member 620 from being separated from the second limiting member 520, respectively.

[0144] Here, as shown in FIG. 7, the second end of the second elastic member 610 includes a first contact curved surface 611, and a first contact flat surface 612 and a second contact flat surface 613 located on both sides of the first contact curved surface 611, so that the second end of the second elastic member 610 can rotate smoothly in the first recessed portion 524, preventing the second end of the second elastic member 610 from being stuck and damaged; the second end of the third elastic member 620 includes a second contact curved surface 621, and a third contact flat surface 622 and a fourth contact flat surface 623 located on both sides of the second contact curved surface 621, so that the second end of the third elastic member 620 can rotate smoothly in the second recessed portion 525, preventing the second end of the third elastic member 620 from being stuck and damaged.

[0145] In the present example, as shown in FIGS. 6 and 7, the shell 100 can include: a first wall body 130, the second limiting member 520 and the third limiting member 530 being arranged on the first wall body 130; the second elastic member 610 and the third elastic member 620 being connected to the first wall body 130 towards the accommodation space 101 side, respectively; in the projection plane parallel to the rotation axis, the projection plane area of the second elastic member 610 and the third elastic member 620 is located outside the projection plane area of the first wall body 130, by arranging the second elastic member 610 and the third elastic member 620 on the first wall body 130 towards the accommodation space 101 side, it can not only ensure that the first wall body 130 does not affect the deformation of the second elastic member 610 and the third elastic member 620, but also can reduce the setting space of the second elastic member 610 and the third elastic member 620, realizing the light and thin of the data line storage device.

[0146] Here, the first wall body 130 can be located in the first half shell 110. At this time, the first half shell 110 includes the first wall body 130 and a side wall located on the peripheral side of the first wall body 130.

[0147] Here, as shown in FIG. 10, the first wall body 130 can further be provided with a first slot 131 and a second slot 132. The first slot 131 is in communication with the accommodating space 101 and corresponds to the position of the second elastic member 610; the second slot 132 is in communication with the accommodating space 101 and corresponds to the position of the third elastic member 620; in the projection plane perpendicular to the rotation axis, the contour line of the first slot 131 is arranged adjacent to the partial contour line of the second elastic member 610, and the contour line of the second slot 132 is arranged adjacent to the partial contour line of the third elastic member 620; so that the deformation space of the second elastic member 610 and the third elastic member 620 can be increased through the first slot 131 and the second slot 132, and the first slot 131 and the second slot 132 can be shielded by the second elastic member 610 and the third elastic member 620, so that the data line storage device is more tidy as a whole.

[0148] Here, the first wall body 130, the second elastic member 610 and the third elastic member 620 can be different parts of the same structural member, so as to be manufactured; at the same time, the elastic assembly 600 formed by part of the structure on the shell 100 can greatly simplify the structure of the data line storage device. As an example, the first wall body 130, the second elastic member 610 and the third elastic member 620 can be integrally formed by injection molding. Of course, the first wall body 130, the second elastic member 610 and the third elastic member 620 can also be different structural members, at this time, the second elastic member 610 and the third elastic member 620 can be fixed to the first wall body 130 by bonding, welding, threaded connection and the like.

[0149] It should be noted that when the elastic assembly 600 is only in the stretched state to provide the second limiting member 520 with the force rotating in the first direction B, the elastic assembly 600 can only include the third elastic member 620. When the elastic assembly 600 provides the second limiting member 520 with the force rotating in the first direction B in the stretched state; the elastic assembly 600 provides the second limiting member 520 with the force rotating in the second direction A in the storage state; the elastic assembly 600 does not provide the second limiting member 520 with the force rotating in the second direction A in the positioning state, the elastic assembly 600 can include the third elastic member 620 and the second elastic member 610, the second elastic member 610 can be arranged to be shorter, in the positioning state, the second elastic member 610 is in contact with the second limiting member 520, but the second elastic member 610 is not deformed and does not provide the deformation force, in the storage state, the second elastic member is deformed and can provide the deformation force.

[0150] It should be noted that in some embodiments, as shown in FIGS. 1 and 15, the accommodating space 101 of the shell 100 can also be referred to as an accommodating cavity; the rotating member 200 is rotatably arranged in the shell 100, and the rotating member 200 can also be referred to as a wheel core; the cable 300 is used for transmitting data, and the cable 300 can also be referred to as a wire body; the rotating position of the rotating member 200 relative to the shell 100 can be adjusted by the limiting assembly 500, and the limiting assembly 500 can also be referred to as an adjusting assembly.

[0151] In some embodiments, as shown in FIGS. 1 and 16, the first limiting member 510 is arranged on the rotating member 200, and the first limiting member 510 can drive part of the movement of the limiting assembly 500, and the first limiting member 510 can also be referred to as a driving wheel; the rotating position of the rotating member 200 relative to the shell 100 can be adjusted by the second limiting member 520, the third limiting member 530 and the first limiting member 510, and the second limiting member 520 can also be referred to as a second adjusting member, and the third limiting member 530 can also be referred to as a first adjusting member.

[0152] In some embodiments, as shown in FIGS. 1 and 17, the first limiting member 510 provides driving force by cooperating with the first protruding portion 521 of the second limiting member 520 through the first groove 511, and the first groove 511 can also be referred to as a transmission groove; and the first protruding portion 521 can also be referred to as a transmission protruding block.

[0153] In some embodiments, as shown in FIGS. 2 and 16, the third limiting member 530 can make the first protruding portion 521 of the second limiting member 520 located in the first groove 511 by cooperating with the second protruding portion 522 of the second limiting member 520 through the third matching portion 1301, so that the rotating member 200 is in a positioning state relative to the shell 100, and the third matching portion 1301 can also be referred to as a positioning structure, and the second protruding portion 522 can also be referred to as a positioning block.

[0154] In some embodiments, as shown in FIGS. 3 and 17, the third limiting member 530 can make the first protruding portion 521 of the second limiting member 520 located outside the first groove 511 by cooperating with the second protruding portion 522 of the second limiting member 520 through the first matching portion 1302, so that the rotating member 200 can be rotated to accommodate the cable 300 to be in a retracted state or an accommodating state, and the first matching portion 1302 can also be referred to as a retraction structure.

[0155] In some embodiments, as shown in FIGS. 4 and 21, the second limiting member 520 can rotate the third limiting member 530 by the third protruding portion 523, and the third protruding portion 523 can also be referred to as a rotating block.

[0156] In some embodiments, as shown in FIG. 12 and FIG. 20, the third matching part 1301 can be a third groove 5313, which can also be referred to as a positioning platform. The first matching part 1302 can be a second groove 5311 for avoiding the first protruding part 521 from the first groove 511, which can also be referred to as an avoiding slot.

[0157] In some embodiments, as shown in FIG. 7 and FIG. 19, the second limiting part 520 is rotatably connected with the shell 100 through a third connecting column 135, which can also be referred to as a second rotating shaft. The third limiting part 530 is rotatably connected with the shell 100 through a second connecting column 134, which can also be referred to as a first rotating shaft.

[0158] As shown in FIG. 15, in some embodiments, the limiting assembly 500 is used to adjust the length of the cable 300 extending out of the shell 100.

[0159] As an example, as shown in FIG. 16, the matching structure can include a third matching part 1301 for cooperating with the second protruding part 522 to lock the pulled-out length of the cable 300 and a first matching part 1302 for rotating the rotating part 200 to retract the pulled-out cable 300, and the third matching part 1301 is provided at least in two series.

[0160] In some implementations of the present disclosure, the matching structure includes a third matching part for cooperating with the second protruding part to lock the pulled-out length of the cable and a first matching part for rotating the rotating part to retract the pulled-out cable; wherein the third matching part is provided at least in two series. In this way, by using the third matching part provided in series, the cable can be continuously positioned during stretching, the length of the adjacent two positions is smaller, and more accurate length adjustment can be achieved. In the case that the length of one stretching cannot meet the use requirement, continuous stretching is used to achieve quick and accurate adjustment, optimize the product performance, and improve the user's use experience and convenience. The data line device of the present disclosure can also have the function of multi-positioning.

[0161] In some embodiments, as shown in FIG. 16, the third matching part 1301 can be provided at least twice, and the first matching part 1302 can be provided at least once. Among them, the number of the third matching part 1301 is greater than the number of the first matching part 1302, and the second protruding part 522 cooperates with the third matching part 1301 at least twice between two times of retraction of the cable 300. That is, during the stretching of the cable 300, the third matching part 1301 in the limiting assembly 500 is continuously arranged, and between the two times of cooperation of the second protruding part 522 and the first matching part 1302, the second protruding part 522 cooperates with the continuously arranged third matching part 1301, which positions the length of the cable 300 multiple times, reduces the length of the cable 300 that can be adjusted each time, and enables the user to adjust the length of the cable 300 more accurately.

[0162] The embodiments of the present disclosure reduce the length that can be adjusted each time by arranging multiple continuous third matching parts between two times of retraction, improve the accuracy of the length adjustment of the cable, enable the user to accurately adjust according to the use demand, improve the use experience of the user, and optimize the product performance.

[0163] In some embodiments, the matching structure can further include a second matching part 1303 located between the first matching part 1302 and the third matching part 1301 in the circumferential direction of the third limiting piece 530; the third protruding part 523 is used for cooperating with the third matching part 1301 and the second matching part 1303 to drive the third limiting piece 530 to rotate, and the second protruding part 522 is used for cooperating with the third matching part 1301 to position the locking rotating piece 200 (see FIG. 16), or the second protruding part 522 is used for cooperating with the first matching part 1302 to make the rotating piece 200 continuously rotate (see FIG. 17).

[0164] It can be understood that during the rotation of the rotating piece 200, the first limiting piece 510 drives the second limiting piece 520 to swing. The third protruding part 523 and the second protruding part 522 are arranged on the second limiting piece 520, and the third protruding part 523 and the second protruding part 522 can swing with the rotation of the second limiting piece 520. During the swinging of the third protruding part 523 and the second protruding part 522 with the second limiting piece 520, the third protruding part 523 and the second protruding part 522 can alternately cooperate with the third limiting piece 530. When the second protruding part 522 swings to cooperate with the third limiting piece 530, the extension or retraction adjustment can be achieved; when the third protruding part 523 swings to cooperate with the third limiting piece 530, the third limiting piece 530 can be rotated (see FIG. 21 and FIG. 4), which prepares for the cooperation of the second protruding part 522 and the third limiting piece 530 next time.

[0165] When the second protruding part 522 cooperates with the third cooperating part 1301, the counterclockwise rotation of the rotating member 200 is limited, and the length of the cable 300 extending out is fixed; when the second protruding part 522 cooperates with the first cooperating part 1302, the counterclockwise rotation of the rotating member 200 is not limited, and the cable 300 is retracted into the shell 100 along with the rotation of the rotating member 200. The cooperation of the third protruding part 523 with the third cooperating part 1301 or the second cooperating part 1303 can drive the third limiting member 530 to rotate by a certain angle, preparing for the cooperation of the second protruding part 522 with the third cooperating part 1301 or the first cooperating part 1302 next time.

[0166] In some embodiments, as shown in FIG. 20, the third cooperating part 1301 is a third groove 5313 opened on the third limiting member 530, and the first cooperating part 1302 is a second groove 5311 opened on the third limiting member 530. Among them, the distance between the bottom surface of the third groove 5313 and the center of the third limiting member 530 is greater than the distance between the bottom surface of the second groove 5311 and the center of the third limiting member 530. It can be understood that the third limiting member 530 is circumferentially provided with a plurality of third grooves 5313 and second grooves 5311, the depth of the third limiting member 530 from the outer edge to the third groove 5313 is D1, and the depth of the third limiting member 530 from the outer edge to the bottom of the second groove 5311 is D2, D1 < D2. During the swinging of the second limiting member 520, the second protruding part 522 can cooperate with the second groove 5311 or the third groove 5313 to realize the switching of the working state of the limiting assembly 500.

[0167] As shown in FIG. 16, when the limiting assembly 500 is in the positioning state, the second protruding part 522 cooperates with the third groove 5313. Due to the depth limitation of the third groove 5313, the depth of the cooperation between the second protruding part 522 and the third limiting member 530 is shallow, which limits the further rotation of the second limiting member 520 along with the first limiting member 510. At this time, the angle of rotation of the second transmission structure 1320 is not enough to avoid the first transmission structure 1310 on the first limiting member 510, which will hinder the further counterclockwise rotation of the first limiting member 510, and the rotating member 200 cannot continue to rotate counterclockwise, and the cable 300 cannot be retracted, so as to fix the length of the cable 300 extending out of the shell 100, thereby playing a positioning role after the stretching gear.

[0168] As shown in FIG. 17, when the limiting assembly 500 is in the retracted state, the second protruding part 522 cooperates with the second groove 5311, and since the depth of the second groove 5311 is large, the second limiting part 520 rotates with the first limiting part 510 until the second protruding part 522 abuts against the bottom of the second groove 5311, at which time the angle of rotation of the second transmission structure 1320 is sufficient to avoid the first transmission structure 1310 on the first limiting part 510, so that the first limiting part 510 rotates counterclockwise without limitation, and the rotating member 200 can also move counterclockwise smoothly, thereby achieving smooth retraction of the data line after extension.

[0169] The third limiting part is controlled to swing at different angles through different cooperation modes of the second protruding part on the third limiting part and the second limiting part, so that positioning at different gears is achieved, and the structure is simple and convenient to assemble.

[0170] In some embodiments, as shown in FIGS. 20 and 21, the third groove 5313 includes a first plane 13012 and a second plane 13013, and the length of the first plane 13012 is greater than the length of the second plane 13013. The third protruding part 523 at least abuts against the first plane 13012 to drive the second limiting part 520 to rotate, and the second protruding part 522 at least abuts against the first plane 13012 to limit the position of the second limiting part 520. It can be understood that when the second limiting part 520 swings to the third protruding part 523 in contact with the third groove 5313, the third protruding part 523 can move along the first plane 13012 to push the third limiting part 530 to rotate, and when the length of the first plane is set to be relatively long, the angle of rotation of the third limiting part 530 can be ensured to meet the accurate cooperation of the second protruding part 522 and the third limiting part 530.

[0171] The length of the first plane of the third groove is greater than the length of the second plane, so that the third groove and the third protruding part have a relatively long contact area, the driving of the third protruding part is more accurate, the next third groove or second groove can be accurately cooperated with the second protruding part, the smooth realization of the product function is ensured, and the product quality is improved.

[0172] In some embodiments, as shown in FIGS. 18 and 20, the profile shape of at least the part of the second protruding part 522 for insertion into the second groove 5311 is matched with the profile shape of the second groove 5311. That is, when the limiting assembly 500 is in the retracted state, the second protruding part 522 can be inserted into the second groove 5311 and fit the profile of the second groove 5311, so that the second limiting part 520 rotates through a sufficient angle and is completely separated from the first limiting part 510, so that the rotating member 200 can rotate smoothly.

[0173] The embodiment of the present disclosure sets the profile of the second groove to completely match the second protruding part, so that the rotating part can be separated from the second limiting part as much as possible during rotation, without affecting the rotation of the rotating part, so that the cable can be smoothly retracted, to ensure the reliability of product function and optimize product quality.

[0174] In some embodiments, as shown in FIG. 17, the first grooves 511 are uniformly distributed along the circumference of the first limiting part 510. The first protruding part 521 cooperates with the first grooves 511. When the limiting assembly 500 is in the positioning state, the first protruding part 521 abuts against the first grooves 511, limiting the further rotation of the first limiting part 510. When the limiting assembly 500 is in the retracted state, the first protruding part 521 is separated from the first grooves 511, so that the first limiting part 510 can rotate without limitation, thereby realizing the retraction of the cable 300.

[0175] The embodiment of the present disclosure sets the profile of the second groove to completely match the second protruding part, so that the rotating part can be separated from the second limiting part as much as possible during rotation, without affecting the rotation of the rotating part, so that the cable can be smoothly retracted, to ensure the reliability of product function and optimize product quality.

[0176] In some embodiments, as shown in FIGS. 17 and 18, the first protruding part 521 has a transmission slope 13202 and a limiting plane 13203. The transmission slope 13202 is inclined towards the direction in which the first limiting part 510 is pulled. It can be understood that the first protruding part 521 on the second limiting part 520 cooperates with the first grooves 511 on the first limiting part 510. Each time the first protruding part 521 changes a cooperating first groove 511, the limiting assembly 500 performs gear shifting, and the first limiting part 510 rotates by a corresponding angle with the rotating part 200, and the length of the cable 300 also changes by a gear of stretching and contraction. When the cable 300 is stretched outward, the extension direction of the transmission slope 13202 of the first protruding part 521 is tangent to the outer edge of the first limiting part 510, and moves along the outer edge of the first limiting part 510. In this process, when the first protruding part 521 passes through the first groove 511, it will fall into the first groove 511 and limit the further rotation of the first limiting part 510. When the limiting assembly 500 is in the positioning state, the limiting plane 13203 on the first protruding part 521 abuts against the first groove 511, limiting the further rotation of the first limiting part 510. At the same time, when the first protruding part 521 falls into the first groove 511 for positioning, the first protruding part 521 and the inner wall of the first groove 511 can collide with each other to emit a prompt sound.

[0177] The first protruding part and the first groove are matched to realize the gear switching, the limiting plane and the transmission slope are arranged to ensure the smooth realization of the winding function, and a prompt sound is emitted when the gear is switched to remind the user that the gear switching is completed, thereby improving the product quality and the user experience.

[0178] In some embodiments, the data line device is a winding device, the rotating member is a winding core, the limiting assembly is an adjusting assembly, the cable is a wire body, the containing space is a containing cavity, the first elastic member is a spring or a clockwork, the third limiting member is a first adjusting member, the first limiting member is a driving wheel, the second limiting member is a second adjusting member, the first recess is a transmission groove, the second connecting column is a first rotating shaft, the third matching part is a positioning structure, the first matching part is a contraction structure, the third connecting column is a second rotating shaft, the elastic assembly is an elastic member, the third protruding part is a pushing block, the second protruding part is a positioning block, the first protruding part is a transmission protruding block, the third recess is a positioning table, and the second recess is an avoiding groove.

[0179] As shown in FIG. 15, the embodiment of the present disclosure provides a winding device (data line device) 1 with multiple gears, which comprises a shell 100, a winding core (rotating member) 200 and an adjusting assembly (limiting assembly) 500. The shell 100 has a containing cavity (containing space) 101 inside for containing a wire body (cable) 300, and the shell 100 is provided with an opening 102 for the wire body (cable) 300 to pass through. The opening 102 is in communication with the containing cavity (containing space) 101. The winding core (rotating member) 200 is arranged in the containing cavity (containing space) 101 and is movably connected with the shell 100. The wire body (cable) 300 is wound on the winding core (rotating member) 200, and the winding core (rotating member) 200 can rotate with the wire body (cable) 300 being pulled out or retracted. Part of the adjusting assembly (limiting assembly) 500 is mounted on the shell 100, and the adjusting assembly (limiting assembly) 500 is used to adjust the length of the wire body (cable) 300 extending out of the shell 100.

[0180] It can be understood that the wheel core (rotating member) 200 is internally provided with an elastic element (first elastic member) 400 such as a coil spring or a clockwork, under the action of an external force, the wheel core (rotating member) 200 rotates, and the elastic element (first elastic member) 400 is elastically deformed, and after the external force is removed, the elastic element (first elastic member) 400 restores the deformation, and the driving force generated can drive the wheel core (rotating member) 200 to rotate. The wire body (cable) 300 is wound on the wheel core (rotating member) 200 and is arranged in the accommodating cavity (accommodation space) 101 in the shell 100 together with the wheel core (rotating member) 200. The wire body (cable) 300 extends out of the shell 100 through the opening 102. When the wire body (cable) 300 is stretched under the action of an external force, the movement of the wire body (cable) 300 exerts a force on the wheel core (rotating member) 200, which drives the wheel core (rotating member) 200 to rotate clockwise; when the external force applied to the wire body (cable) 300 is removed, the wheel core (rotating member) 200 rotates counterclockwise, and the wire body (cable) 300 is retracted with the counterclockwise rotation of the wheel core (rotating member) 200. The adjustment assembly (limiting assembly) 500 can partially abut against the wheel core (rotating member) 200. The wheel core (rotating member) 200 drives the adjustment assembly (limiting assembly) 500 to move during rotation, and the adjustment assembly (limiting assembly) 500 limits the rotation of the wheel core (rotating member) 200, thereby adjusting the length of the wire body (cable) 300 extending out of the shell 100.

[0181] As an example, as shown in FIG. 16, the adjustment assembly (limiting assembly) 500 includes a first positioning member (third limiting member) 530, the first positioning member (third limiting member) 530 includes a positioning structure (third cooperation part) 1301 for cooperating with the wheel core (rotating member) 200 to lock the length of the wire body (cable) 300 pulled out, and a contraction structure (first cooperation part) 1302 for rotating the wheel core (rotating member) 200 to retract the wire body (cable) 300 pulled out, and the positioning structure (third cooperation part) 1301 is provided at least two in series. That is, the adjustment assembly (limiting assembly) 500 is provided with the positioning structure (third cooperation part) 1301 and the contraction structure (first cooperation part) 1302. During the process of the wire body (cable) 300 being stretched to drive the wheel core (rotating member) 200 to rotate, the wheel core (rotating member) 200 cooperates with the positioning structure (third cooperation part) 1301 or the contraction structure (first cooperation part) 1302 on the adjustment assembly (limiting assembly) 500.

[0182] The cooperation between the positioning structure (third cooperation part) 1301 and the wheel core (rotary part) 200 can include indirect cooperation between the positioning structure (third cooperation part) 1301 and the wheel core (rotary part) 200. For example, the positioning structure (third cooperation part) 1301 can cooperate with another structure on the wheel core (rotary part) 200 through a structure; the cooperation between the wheel core (rotary part) 200 and the contraction structure (first cooperation part) 1302 can be indirect cooperation between the wheel core (rotary part) 200 and the contraction structure (first cooperation part) 1302; for example, a structure on the wheel core (rotary part) 200 cooperates with the contraction structure (first cooperation part) 1302 through another structure.

[0183] As an example, as shown in FIG. 16, when the wheel core (rotary part) 200 cooperates with the positioning structure (third cooperation part) 1301, the reverse rotation of the wheel core (rotary part) 200 is limited, and the length of the wire body (cable) 300 extending out of the shell 100 is fixed, thereby playing a role of positioning the wire body (cable) 300. As shown in FIG. 17, when the wheel core (rotary part) 200 cooperates with the contraction structure (first cooperation part) 1302, the reverse rotation of the wheel core (rotary part) 200 is not limited, and the part of the wire body (cable) 300 extending out of the shell 100 will retract into the shell 100 along with the reverse rotation of the wheel core (rotary part) 200, thereby playing a role of contracting the wire body (cable) 300. Since the positioning structure (third cooperation part) 1301 in the adjustment assembly (limiting assembly) 500 is arranged at least continuously for two times, that is, the wire body (cable) 300 can be continuously positioned during the stretching of the wire body (cable) 300, if the length of one-time stretching cannot meet the use requirement of the user, the wire body (cable) 300 can be stretched again and positioned, until the wire body (cable) 300 is adjusted to a proper length.

[0184] In some embodiments, the present disclosure provides a winding device (data line device) with multiple positioning gears, which comprises a housing, a wheel core (rotating member) and an adjusting assembly (limiting assembly). The housing has an accommodating cavity (accommodating space) for accommodating a wire body (cable) therein, and an opening for the wire body (cable) to pass through, which is in communication with the accommodating cavity (accommodating space). The wheel core (rotating member) is arranged in the accommodating cavity (accommodating space) and movably connected with the housing. The wire body (cable) is wound on the wheel core (rotating member) and the wheel core (rotating member) can rotate with the wire body (cable) being pulled out or retracted. Part of the adjusting assembly (limiting assembly) is mounted on the housing, and the adjusting assembly (limiting assembly) is used to adjust the length of the wire body (cable) extending out of the housing. The adjusting assembly (limiting assembly) comprises a positioning structure (third matching part) for cooperating with the wheel core (rotating member) to lock the length of the wire body (cable) pulled out and a retraction structure (first matching part) for rotating the wheel core (rotating member) to retract the wire body (cable) pulled out. The positioning structure (third matching part) is arranged continuously at least twice. In this way, the wire body (cable) can be continuously positioned during the stretching process by using the continuously arranged positioning structure (third matching part). The length of the wire body (cable) pulled out by the adjacent two positions is smaller, and the length can be adjusted more accurately. In the case that the length of the wire body (cable) pulled out by one stretching cannot meet the use requirement, the wire body (cable) can be quickly and accurately adjusted by continuous stretching, the product performance is optimized, and the user's use experience and convenience are improved.

[0185] In some embodiments, as shown in FIG. 16, the positioning structure (third matching part) 1301 is arranged at least twice, and the retraction structure (first matching part) 1302 is arranged at least once. The number of the positioning structure (third matching part) 1301 is greater than the number of the retraction structure (first matching part) 1302, and the wheel core (rotating member) 200 cooperates with the positioning structure (third matching part) 1301 at least twice between the two retractions of the wire body (cable) 300. That is, the positioning structure (third matching part) 1301 in the adjusting assembly (limiting assembly) 500 is arranged continuously during the stretching of the wire body (cable) 300. Between the two cooperations of the wheel core (rotating member) 200 and the retraction structure (first matching part) 1302, the wheel core (rotating member) 200 cooperates with the continuously arranged positioning structure (third matching part) 1301, and the length of the wire body (cable) 300 is positioned multiple times, so that the length of the wire body (cable) 300 pulled out by each positioning is reduced, and the user can adjust the length of the wire body (cable) 300 more accurately.

[0186] The present disclosure sets multiple continuous positioning structures (third matching parts) between the two retractions, reduces the length that can be adjusted by each positioning, improves the accuracy of the length adjustment of the wire body (cable), and enables the user to accurately adjust the length according to the use requirement, thereby improving the user's use experience and optimizing the product performance.

[0187] In some embodiments, as shown in FIGS. 15 and 16, the winding device (data line device) can further include a resilient element (first resilient member) 400 such as a coil spring or a clockwork spring, which is connected to the wheel core (rotating member) 200 and the housing 100 respectively by bonding, clamping, welding or other connecting methods. The resilient element (first resilient member) 400 is used to generate a driving force for the wheel core (rotating member) 200 to retract the line body (cable) 300. The adjusting assembly (limiting assembly) 500 can further include a driving wheel (first limiting member) 510 connected to the wheel core (rotating member) 200 to rotate with the wheel core (rotating member) 200. The driving wheel (first limiting member) 510 is provided with a first transmission structure 1310 connected to part of the adjusting assembly (limiting assembly) 500 to drive part of the adjusting assembly (limiting assembly) 500 to move. It can be understood that the wheel core (rotating member) 200 is provided with a clockwork spring (first resilient member) 400, and the line body (cable) 300 is wound around the wheel core (rotating member) 200. When the line body (cable) 300 is stretched, it will drive the wheel core (rotating member) 200 to rotate forward. At this time, the clockwork spring (first resilient member) 400 provided in the wheel core (rotating member) 200 is deformed. When the external force is removed, the clockwork spring (first resilient member) 400 restores the deformation to drive the wheel core (rotating member) 200 to rotate reversely, thereby driving the line body (cable) 300 to retract. The driving wheel (first limiting member) 510 is fixed on the wheel core (rotating member) 200 and rotates with the wheel core (rotating member) 200. The first transmission structure 1310 on the driving wheel (first limiting member) 510 can cooperate with part of the adjusting assembly (limiting assembly) 500. The first transmission structure 1310 can drive part of the adjusting assembly (limiting assembly) 500 to move during the rotation of the driving wheel (first limiting member) 510 with the wheel core (rotating member) 200. During the movement, the rotation of the driving wheel (first limiting member) 510 is controlled by part of the adjusting assembly (limiting assembly) 500, thereby limiting the rotation of the wheel core (rotating member) 200 to achieve the stretching or retraction of the line body (cable) 300.

[0188] The wheel core (rotating member) is provided with a driving wheel (first limiting member), and the driving wheel (first limiting member) is provided with a first transmission structure cooperating with part of the adjusting assembly (limiting assembly). Part of the adjusting assembly (limiting assembly) is driven to rotate by the first transmission structure, so as to achieve the extension and retraction of the line body (cable). The transmission is reliable, the structure of the wheel core (rotating member) is simplified, the assembly is facilitated, and the production efficiency is improved.

[0189] In some embodiments, as shown in FIGS. 17 and 18, the adjusting assembly (limiting assembly) 500 further comprises a second limiting member (second limiting piece) 520, a poking block (third protruding part) 523 and a positioning block (second protruding part) 522. The second limiting member (second limiting piece) 520 is connected with the shell 100 through a second rotating shaft (third connecting column) 135 (see FIG. 19), and the second limiting member (second limiting piece) 520 is provided with a second transmission structure 1320, the first transmission structure 1310 and the second transmission structure 1320 are matched and driven to limit the angle of rotation of the driving wheel (first limiting piece) 510, the first limiting member (third limiting piece) 530 is rotatably connected with the shell 100 through a first rotating shaft (second connecting column) 134 (see FIG. 19), the positioning structure (third matching part) 1301 and the contraction structure (first matching part) 1302 are both arranged on the first limiting member (third limiting piece) 530, and the first limiting member (third limiting piece) 530 further comprises a second matching part 1303 between the contraction structure (first matching part) 1302 and the positioning structure (third matching part) 1301 in the circumferential direction; the poking block (third protruding part) 523 is arranged on the second limiting member (second limiting piece) 520, and the poking block (third protruding part) 523 is used for cooperating with the positioning structure (third matching part) 1301 and the second matching part 1303 to drive the first limiting member (third limiting piece) 530 to rotate, the positioning block (second protruding part) 522 is arranged on the second limiting member (second limiting piece) 520 and is spaced apart from the poking block (third protruding part) 523, and the positioning block (second protruding part) 522 is used for cooperating with the positioning structure (third matching part) 1301 to position the locking wheel core (rotating member) 200 (see FIG. 16), or the positioning block (second protruding part) 522 is used for cooperating with the contraction structure (first matching part) 1302 to make the wheel core (rotating member) 200 continuously rotate (see FIG. 17).

[0190] It can be understood that the adjusting assembly (limiting assembly) 500 has a second adjusting member (second limiting member) 520 and a first adjusting member (third limiting member) 530. The second adjusting member (second limiting member) 520 is connected to the shell 100 through a second rotating shaft (third connecting column) 135 and has a second transmission structure 1320 capable of cooperating with a first transmission structure 1310. During rotation of the wheel core (rotating member) 200, the first transmission structure 1310 drives the second transmission structure 1220, thereby driving the second adjusting member (second limiting member) 520 to swing. A poking block (third protruding part) 523 and a positioning block (second protruding part) 522 are arranged on the second adjusting member (second limiting member) 520 and can swing with rotation of the adjusting member. The first adjusting member (third limiting member) 530 is connected to the shell 100 through a first rotating shaft (second connecting column) 134 and is located between the poking block (third protruding part) 523 and the positioning block (second protruding part) 522. Then, during swinging of the poking block (third protruding part) 523 and the positioning block (second protruding part) 522 with the second adjusting member (second limiting member) 520, the poking block (third protruding part) 523 and the positioning block (second protruding part) 522 can cooperate with the first adjusting member (third limiting member) 530. When the positioning block (second protruding part) 522 swings to cooperate with the first adjusting member (third limiting member) 530, adjustment of extension or contraction can be achieved. When the poking block (third protruding part) 523 swings to cooperate with the first adjusting member (third limiting member) 530, the first adjusting member (third limiting member) 530 can be poked to rotate (see FIG. 21 and FIG. 4), thereby preparing for cooperation of the positioning block (second protruding part) 522 with the first adjusting member (third limiting member) 530 next time.

[0191] Since the positioning structure (third cooperation part) 1301 and the contraction structure (first cooperation part) 1302 are both arranged on the first adjusting member (third limiting member) 530, when the positioning block (second protruding part) 522 cooperates with the positioning structure (third cooperation part) 1301, counterclockwise rotation of the wheel core (rotating member) 200 is limited and the length of the wire body (cable) 300 is fixed. When the positioning block (second protruding part) 522 cooperates with the contraction structure (first cooperation part) 130, counterclockwise rotation of the wheel core (rotating member) 200 is not limited and the wire body (cable) 300 is retracted into the shell 100 with rotation of the wheel core (rotating member) 200. Cooperation of the poking block (third protruding part) 523 with the positioning structure (third cooperation part) 1301 or the second cooperation part 1303 can both poke the first adjusting member (third limiting member) 530 to rotate by a certain angle, thereby preparing for cooperation of the positioning block (second protruding part) 522 with the positioning structure (third cooperation part) 1301 or the contraction structure (first cooperation part) 1302 next time.

[0192] The embodiments of the present disclosure can realize accurate gear switching of the wire body (cable) in the stretching process through the cooperation of the positioning block (second protruding part) on the second position adjusting member (second limiting member) and the actuating block (third protruding part) on the first position adjusting member (third limiting member), avoid the failure of the winding device (data line device), optimize the product quality, and further improve the user experience.

[0193] In some embodiments, as shown in FIG. 16, the adjusting assembly (limiting assembly) 500 further comprises an elastic member (elastic assembly) 600. The elastic member (elastic assembly) 600 is installed on the shell 100 and abuts against the second position adjusting member (second limiting member) 520 to drive the second position adjusting member (second limiting member) 520 to reciprocally swing around the second rotating shaft (third connecting column) 135.

[0194] As shown in FIGS. 16-18, during the rotation of the driving wheel (first limiting member) 510, the second position adjusting member (second limiting member) 520 swings with the rotation of the driving wheel (first limiting member) 510. The elastic member (elastic assembly) 600 is installed on the inner wall of the shell 100 and located on the side of the second position adjusting member (second limiting member) 520 away from the driving wheel (first limiting member) 510. After the second position adjusting member (second limiting member) 520 rotates by a certain angle, the elastic member (elastic assembly) 600 limits the rotation of the second position adjusting member (second limiting member) 520, so that the second position adjusting member (second limiting member) 520 can be returned in time after the rotation.

[0195] The embodiments of the present disclosure control the angle of the swing of the second position adjusting member (second limiting member) by setting the elastic member (elastic assembly), prevent the second position adjusting member (second limiting member) from rotating too much and failing to return in time, ensure the normal operation of the gear adjusting function, improve the quality of the product, and optimize the performance of the product.

[0196] In some embodiments, as shown in FIG. 20, the positioning structure (third matching part) 1301 is a positioning platform (third groove) 5313 formed on the first positioning member (third limiting member) 530, and the retraction structure (first matching part) 1302 is an avoidance groove (second groove) 5311 formed on the first positioning member (third limiting member) 530. The distance between the bottom surface of the positioning platform (third groove) 5313 and the center of the first positioning member (third limiting member) 530 is greater than the distance between the bottom surface of the avoidance groove (second groove) 5311 and the center of the first positioning member (third limiting member) 530. It can be understood that the first positioning member (third limiting member) 530 is circumferentially provided with a plurality of positioning platforms (third grooves) 5313 and avoidance grooves (second grooves) 5311, the depth from the outer edge of the first positioning member (third limiting member) 530 to the positioning platform (third groove) 5313 is D1, the depth from the outer edge of the first positioning member (third limiting member) 530 to the bottom of the avoidance groove (second groove) 5311 is D2, and D1 < D2. During the oscillation of the second positioning member (second limiting member) 520, the positioning block (second protruding part) 522 can cooperate with the avoidance groove (second groove) 5311 or the positioning platform (third groove) 5313 to switch the working state of the adjusting assembly (limiting assembly) 500.

[0197] As shown in FIG. 16, when the adjusting assembly (limiting assembly) 500 is in the positioning state, the positioning block (second protruding part) 522 cooperates with the positioning platform (third groove) 5313. Due to the depth limitation of the positioning platform (third groove) 5313, the depth of the cooperation between the positioning block (second protruding part) 522 and the first positioning member (third limiting member) 530 is shallow, which limits the continuous rotation of the second positioning member (second limiting member) 520 with the driving wheel (first limiting member) 510. At this time, the angle of rotation of the second transmission structure 1320 is not enough to avoid the first transmission structure 1310 on the driving wheel (first limiting member) 510, which will hinder the further counterclockwise rotation of the driving wheel (first limiting member) 510, and the wheel core (rotating member) 200 cannot continue to rotate counterclockwise, the length of the wire body (cable) 300 fixedly stretched out of the shell 100 cannot be recovered, thereby playing a positioning role after the stretching gear.

[0198] As shown in FIG. 17, when the adjusting assembly (limiting assembly) 500 is in the retracted state, the positioning block (second protruding part) 522 cooperates with the avoiding groove (second groove) 5311, and since the depth of the avoiding groove (second groove) 5311 is large, the second positioning member (second limiting member) 520 rotates with the driving wheel (first limiting member) 510 until the positioning block (second protruding part) 522 abuts against the bottom of the avoiding groove (second groove) 5311, at which time the angle of rotation of the second transmission structure 1320 is sufficient to avoid the first transmission structure 1310 on the driving wheel (first limiting member) 510, so that the driving wheel (first limiting member) 510 rotates counterclockwise without limitation, and the wheel core (rotating member) 200 can also move counterclockwise smoothly, thereby achieving smooth retraction of the data line after the data line is stretched out.
