Description

Technical Field

[0001] The present application relates to the technical field of digital products, and in particular to a two-way stretched automatic storage magnetic flat wire. Background Art

[0002] With the development of science and technology, the number and types of electronic products have increased dramatically, and the demand for cables has also increased significantly. Due to their slender characteristics, data cables are usually tangled together when carried. Therefore, based on this background, a two-way stretchable automatic storage magnetic flat cable that can be wound together for easy carrying has been introduced.

[0003] In the Chinese patent application document CN116706621A, a bidirectionally stretched automatic storage magnetic flat wire is proposed, which adds a layer of magnetic material to the wrapping material of the wire core to make the wire magnetic. Two data connectors are respectively set at both ends of the wire to form a data cable, and then the single data cable is wound into a roll for easy storage. When the data cable rolled in the above manner is used, the data connector wound on the inner coil needs to be pulled out for use, which causes the coil to be messy and inconvenient to use the data cable.

[0004] In another Chinese patent application document CN117238587A, a method for making a biaxially stretched automatic storage magnetic flat wire is proposed, in which a magnetic layer is formed by mixing a glue layer and magnetic powder, and a single wire is straightened and the magnetic layer is magnetized by a magnetizer. However, after magnetization, the single data line is stacked and wound into a roll. At this time, since the data line connectors are arranged at both ends of the data line, when the stacked data line is in use, the two ends can be pulled out separately to connect different electronic devices. However, when the data connectors at both ends of the stacked and rolled data line are pulled out, the volume of the stacked part is too large, which makes it inconvenient to use the data line.

[0005] In summary, it is necessary to provide a bidirectional stretchable automatic storage magnetic flat wire that is easy to place and will not be messy when in use. Utility Model Content

[0006] In view of this, it is necessary to provide a bidirectional stretchable automatic storage magnetic flat wire that is easy to place and will not be messy, so as to solve the above problems.

[0007] The embodiment of the present application provides a biaxially stretched automatic storage magnetic flat wire, comprising a wire filled with a magnetic material layer and a first connector and a second connector provided at both ends of the wire.

[0008] The wire includes a first section and a second section connected in sequence. The first section and the second section are arranged in a folded manner. The first connector is provided at the end of the first section, and the second connector is provided at the end of the second section. When the first section and the second section are wound together, the first connector and the second connector are respectively located in the outermost two circles.

[0009] In at least one embodiment of the present application, when the wire is straightened, the first section has a first surface, the second section has a second surface in the same plane as the first surface, and the polarities of the first surface and the second surface are opposite.

[0010] In at least one embodiment of the present application, the first section and the second section are arranged in a folded manner with the first surface fitting the second surface, so that the first connector and the second connector are wound to the outermost two circles.

[0011] In at least one embodiment of the present application, the second section has a third surface opposite to the second surface. The first section and the second section are arranged in a side-by-side folded manner, and the first surface and the third surface are in the same plane, so that both the first connector and the second connector are wound to the outermost circle.

[0012] In at least one embodiment of the present application, the wire further includes a bent section provided between the first section and the second section for the first section and the second section to be bent at the bent section.

[0013] In at least one embodiment of the present application, the wire includes a wire core, a magnetic attraction layer wrapped around the wire core, and a sheath layer wrapped around the magnetic attraction layer;

[0014] The magnetic attraction layer includes a third section corresponding to the first section, a fourth section corresponding to the second section, and a fifth section corresponding to the bent section;

[0015] The third section and the fourth section are formed by mixing a magnetic layer and an adhesive layer, and the fifth section is an adhesive layer.

[0016] In at least one embodiment of the present application, the wire includes a wire core, at least two layers of magnetic attraction layers wrapped around the wire core, and a sheath layer wrapped around the magnetic attraction layers;

[0017] One layer of the magnetic attraction layer is wrapped around the first section, and the other layer of the magnetic attraction layer is wrapped around the second section.

[0018] In at least one embodiment of the present application, the end of the first section and the first connector are wound to the second outermost layer, and the end of the second section and the second connector are wound to the outermost layer;

[0019] When observing along the winding height direction of the bidirectional stretch automatic storage magnetic flat wire, the first section and the first connector protrude from the second section and the second connector.

[0020] In at least one embodiment of the present application, when the wire is wound, the bidirectional stretch automatic storage magnetic flat wire includes an adsorption area and a connection area;

[0021] The adsorption area is located in the inner circle, the connection area is located in the outer circle, and the first connector and the second connector are located in the connection area.

[0022] In at least one embodiment of the present application, the bent section is located in the adsorption area after winding.

[0023] In at least one embodiment of the present application, when observing along the direction perpendicular to the adsorption area, the area where the bent section is located after winding is within the adsorption area.

[0024] In at least one embodiment of the present application, the bent section forms a relatively arranged first winding opening and a second winding opening at the center of the adsorption area after winding, and the first winding opening and the second winding opening are used for a person's finger or mechanical equipment to pass through.

[0025] The above-provided bidirectional stretch automatic storage magnetic flat wire is coiled by folding the first section and the second section together, so that the first connector and the second connector are respectively located in the outermost two circles or both in the outermost circle. When the bidirectional stretch automatic storage magnetic flat wire is in use, the first connector and the second connector can be peeled off from the outermost two circles respectively to be connected to the corresponding electronic devices. And since the wire is filled with magnetic material, after the first connector and the second connector in the outer circle are peeled off, the wound inner circle can still be adsorbed on the iron shell near the electronic device. It avoids the problem that one connection end of the existing bidirectional stretch automatic storage magnetic flat wire is wound to the inner circle, resulting in wire chaos when pulled out, and also avoids the problem that it is difficult to adsorb due to the formation of a three-dimensional shape in the inner layer of the coil when the wire is wound into a stacked coil, thus realizing the problem of being easy to place and the wire not being chaotic.

Detailed implementation manners

[0036] Next, the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0037] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "provided on" another component, it can be directly provided on the other component or there may be an intermediate component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used herein are only for the purpose of illustration.

[0038] The embodiments of the present application provide a bidirectional stretch automatic storage magnetic flat wire, including a wire filled with a magnetic adsorption material layer and a first connector and a second connector provided at both ends of the wire.

[0039] The wire includes a first section and a second section connected in sequence. The first section and the second section are arranged in a folded manner. The first connector is provided at the end of the first section, and the second connector is provided at the end of the second section. When the first section and the second section are wound together, the first connector and the second connector are respectively located in the outermost two circles or both located in the outermost circle.

[0040] The above-mentioned bidirectional stretch automatic storage magnetic flat wire is wound together after folding the first section and the second section, so that the first connector and the second connector are respectively located in the outermost two circles or both located in the outermost circle. When the bidirectional stretch automatic storage magnetic flat wire is in use, the first connector and the second connector can be respectively peeled off from the outermost two circles to be connected to the corresponding electronic devices. And because the wire is filled with magnetic material, after the first connector and the second connector on the outer circle are peeled off, the wound inner circle can still be adsorbed on the iron shell near the electronic device. This avoids the problem that one connection end of the existing bidirectional stretch automatic storage magnetic flat wire is wound to the inner circle, resulting in chaos of the wire when it is pulled out, and also avoids the problem that it is difficult to adsorb due to the formation of a three-dimensional shape in the inner layer of the coil when the wire is wound into a stacked coil, thus realizing the problem of being convenient to place and the wire not being chaotic.

[0041] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0042] Please refer to Figures 1-6 The present application provides a bidirectional stretch automatic storage magnetic flat wire 100, including a wire 10 filled with a magnetic material layer and a first connector 20 and a second connector 30 provided at both ends of the wire 10. The wire 10 includes a first section 11 and a second section 12 connected in sequence. The first section 11 and the second section 12 are arranged in a folded manner. The first connector 20 is provided at the end of the first section 11, and the second connector 30 is provided at the end of the second section 12. When the first section 11 and the second section 12 are wound together, the first connector 20 and the second connector 30 are respectively located in the outermost two circles.

[0043] It should be noted that with the progress of technology, the number and types of electronic devices are increasing, and the demand for data cables is gradually rising. Therefore, in the development process of data cables, it started from the simplest single wire bundle. Due to the need for connection, the wire bundle needs to be able to meet a certain length to ensure the connection between two electrical devices. Therefore, for the initial single wire bundle, when the length of the wire bundle is long, during the use and carrying process by the user, the wire bundle will be too long, resulting in the part corresponding to the wire bundle occupying more space during use, making the occupied space messy and taking up more space. Based on this background, magnetic data cables have come onto the stage of history.

[0044] When a magnetic data cable is first put on the market, magnets or magnetic strips are usually set at its ends to connect between the two ends through the magnets or magnetic strips. However, the connection is generally difficult at an angle and requires aligning the two magnets.

[0045] Furthermore, in order to facilitate the winding of the bidirectional stretch automatic retractable magnetic flat wire 100, the bidirectional stretch automatic retractable magnetic flat wire 100 described in patent application documents CN116706621A or CN117238587A is cited in the prior art. However, in the patent document CN116706621A, since the entire data cable is composed of a single data cable, when it is wound, one connector is wound in the innermost layer and the other connector is wound in the outermost layer. When the bidirectional stretch automatic retractable magnetic flat wire 100 is in use, the connector in the innermost layer and the connector in the outermost layer need to be pulled out for use. When the connector in the innermost layer is pulled out for use, it will damage the winding method of the wire coil and cause the problem of wire 10 chaos. In CN117238587A, by laminating the wire harnesses, both connectors are on the outside. However, when in use, when the two connectors on the outermost layer are pulled out for use, the middle part of the wound coil is a three-dimensional structure and occupies a large space, and it is difficult to adsorb or place it in a certain place, resulting in the problem of space waste.

[0046] Based on this, for the bidirectional stretch automatic retractable magnetic flat wire 100 provided in this application, the first section 11 and the second section 12 are folded and then wound together, so that the first connector 20 and the second connector 30 are respectively located in the outermost two layers, so that when the bidirectional stretch automatic retractable magnetic flat wire 100 is in use, the first connector 20 and the second connector 30 can be respectively peeled off from the outermost two layers and connected to the corresponding electronic devices. And since the wire 10 is filled with a magnetic material, after the first connector 20 and the second connector 30 on the outer layer are peeled off, the wound inner layer can still be adsorbed on the iron shell near the electronic device. It avoids the problem that one connection end of the existing bidirectional stretch automatic retractable magnetic flat wire 100 is wound to the inner layer and the wire 10 is chaotic when it is pulled out, and also avoids the problem that it is difficult to adsorb due to the formation of a three-dimensional shape in the inner layer of the coil caused by winding the wire 10 into a laminated coil, thus realizing the problem of being easy to place and the wire 10 not being chaotic.

[0047] It should be noted that the bi-directionally stretched automatic retractable magnetic flat wire 100 described in this application can be used for connecting two electrical devices, such as connecting a mobile phone to a computer, or for connecting other electrical devices, such as connecting a TV set to a set-top box. Through the above solution, the first connector 20 and the second connector 30 are stretched out and respectively inserted into the TV set and the set-top box. The coiled part of the coil has magnetism and is in a planar structure, and can be directly attached to the iron box part of the TV set or the set-top box. The operation is simple and does not occupy much space, and it is convenient to place and the wire harness will not be chaotic due to being pulled out from the inner circle.

[0048] In a specific embodiment, when the wire 10 is straightened, the first section 11 has a first surface 11a, the second section 12 has a second surface 12a that is in the same plane as the first surface 11a, and the polarities of the first surface 11a and the second surface 12a are opposite.

[0049] It should be noted that when magnetizing a traditional magnetic data cable (such as in the patent application document CN116706621A), the following steps are usually used:

[0050] 1. Position the metal wire and the glue layer: Before magnetizing multiple metal wires and the glue layer, it is necessary to position them. Usually, the wire 10 is straightened and stabilized by fixing both ends to ensure the accuracy of the magnetizing process.

[0051] 2. Use a magnetic charger for magnetization:

[0052] Place multiple formed metal wires with a glue layer in the magnetic charger and start the magnetization operation. During the magnetization process, the magnetic charger magnetizes the glue layer to generate different magnetic poles on both sides of the glue layer.

[0053] 3. Form magnetic poles:

[0054] The first surface 11a of the glue layer is magnetized to one polarity (such as the S pole), and the second surface 12a is magnetized to the opposite polarity (such as the N pole). These two magnetic poles attract each other to ensure the magnetic attraction effect.

[0055] 4. Take out and check the magnetism:

[0056] After the magnetization is completed, take out the glue layer and the metal wire from the magnetic charger and check their magnetic effects.

[0057] The difference between the present application and the prior art is that, in order to prevent the first connector 20 or the second connector 30 from being wound into the innermost circle due to the winding of a single wire 10, which may cause the arrangement of the wire 10 to be chaotic when it is pulled out, the wire 10 is divided into a first section 11 and a second section 12, and the first section 11 and the second section 12 are coiled by being folded. During the magnetization process, when the folded first section 11 and second section 12 are positioned as a whole and magnetized by a magnetizer, since two different magnetic poles will be formed at both ends of the magnetizer, two different magnetic poles will be formed at the part where the first section 11 and the second section 12 are in contact, that is, the first surface 11a and the second surface 12a. Please refer specifically to Figure 3 and Figure 4 . When two mutually contacting surfaces with opposite polarities (i.e., the first surface 11a and the second surface 12a) are turned over and straightened, the first surface 11a and the second surface 12a are located in the same plane. At this time, they are in the same plane and have opposite polarities.

[0058] In a specific embodiment, the above magnetization process is as follows: First, provide at least two or more metal wires, usually copper wires or copper alloy wires. Then, an insulating layer is wrapped around the outer surface of each metal wire to avoid short circuits or signal interference in subsequent processes. One end of the metal wire is fixed on the first storage member, and the metal wire is wound around the storage member, and the other end is fixed on the second storage member. The multiple metal wires are straightened for positioning to ensure that the metal wires remain flat and do not intersect during operation. Then, to control the shape and size of the glue layer, first place the metal wires in a mold. The mold is used to define the cross-sectional shape of the glue layer. Use a rubber coating machine to inject a glue liquid composed of a mixture of rubber and magnetic powder into the mold. The glue liquid becomes fluid after heating and can uniformly coat the surrounding of the metal wires. After the glue liquid is injected into the mold, it needs to be cooled to solidify and form a glue layer. During this process, the glue layer wraps around the outside of the multiple metal wires and fills the space between the metal wires. Before the magnetization treatment, the multiple metal wires already coated with the glue layer need to be positioned again to ensure the stability of the wire 10 during the magnetization process. Use a magnetizer to magnetize the glue layer. Place the multiple metal wires coated with the glue layer into the magnetizer, start the magnetization program, and the magnetizer will magnetize the two sides of the glue layer to different polarities, one side is the S pole and the other side is the N pole. Then, place the magnetized multiple metal wires and the glue layer into an oven, set the baking temperature to 80°C - 110°C, and the time to 25 - 35 minutes. Bake the magnetized glue layer within the set temperature and time to make it solidify and take shape. Then, form a protective layer on the outer surface of the glue layer, usually wrapped with braided wire, and control the thickness of the protective layer not to exceed 0.6 mm. Use special equipment to uniformly wrap the protective layer outside the glue layer to ensure that the protective layer can provide additional mechanical and electromagnetic protection to the glue layer. Then, use a cutting machine to cut the multiple metal wires coated with the magnetic glue layer to the required length. This step can be carried out after the magnetization treatment is completed, or can be performed after other steps. Then, prepare the first connector and the second connector, and weld them to both ends of the multiple metal wires respectively. It should be noted that before welding, use a wire stripper to remove the glue layer at both ends of the multiple metal wires to expose the metal wire part for welding. Then, in the winding operation, use a jig with a spiral partition structure. There are groove structures on the periphery of the jig for placing the multiple metal wires and their external magnetic glue layer. Place the multiple metal wires and their glue layer in the groove structures in sequence and wind them in order to form multiple turns of magnetic attraction coils. Ensure that the adjacent magnetic attraction coils are arranged in sequence and have a tight structure. Finally, after the winding is completed, place the jig and the magnetic attraction cable into the oven again, set the corresponding baking temperature and time, and perform a second baking treatment on the wound magnetic attraction cable within the preset temperature and time to ensure the shaping and stability of the magnetic layer.

[0059] It can be understood that in the above specific embodiments, the magnetic attraction material layer is formed in the wire 10 by mixing the adhesive layer with magnetic powder and then baking, curing, cutting, welding joints, winding, and baking again. However, the method of forming the magnetic attraction material layer is not limited to this. For example, in another embodiment, a magnetic strip can be directly buried, or magnetic powder can be filled.

[0060] Please refer specifically to Figures 1-6 , in the first embodiment, the first section 11 and the second section 12 are folded in half, and the first surface 11a is attached to the second surface 12a, so as to wind the first connector 20 and the second connector 30 to the outermost two turns.

[0061] Further, please continue to refer to Figure 1 , Figures 3-6 , in a specific embodiment, the wire 10 further includes a bent section 13, and the bent section 13 is disposed between the first section 11 and the second section 12 for the first section 11 and the second section 12 to be bent at the bent section 13.

[0062] It should be noted that the above method is to facilitate the bending of the first section 11 and the second section 12 at the bent section 13 by providing the bent section 13.

[0063] Furthermore, in order to ensure the stability of the magnetic field of the bidirectional stretching automatic storage magnetic attraction flat wire 100 and prevent the magnetic field at the bent section 13 from affecting the magnetic distribution of the first section 11 and the second section 12 or repelling the first section 11 or the second section 12, there is no magnetic field distribution at the bent section 13, which specifically includes the following two embodiments.

[0064] Embodiment 1: The wire 10 includes a wire core 101, a magnetic attraction layer 102 disposed around the wire core 101, and a sheath layer 103 disposed around the magnetic attraction layer 102; the magnetic attraction layer 102 includes a third section (not shown in the figure) corresponding to the first section 11, a fourth section (not shown in the figure) corresponding to the second section 12, and a fifth section (not shown in the figure) corresponding to the bent section 13; the third section and the fourth section are formed by mixing a magnetic layer and an adhesive layer, and the fifth section is an adhesive layer.

[0065] It can be understood that in the above Embodiment 1, the magnetic attraction layer 102 is segmented, and only the adhesive layer is used at the bent section 13 to eliminate the problem of the magnetic attraction layer 102 generating magnetism at the bent section 13.

[0066] Embodiment 2: The wire 10 includes a wire core 101, at least two magnetic attraction layers 102 disposed around the wire core 101, and a sheath layer 103 disposed around the magnetic attraction layers 102; one magnetic attraction layer 102 is disposed around the first section 11, and the other magnetic attraction layer 102 is disposed around the second section 12.

[0067] It can be understood that in the above Embodiment 2, by setting the magnetic attraction layers 102 to two layers, the two magnetic attraction layers 102 are directly disposed around the first section 11 and the second section 12, and the magnetic attraction layers 102 are avoided at the bending section 13 to avoid the problem of magnetism generation at the bending section 13.

[0068] Further, in order to facilitate the pulling out of the first connector 20 and the second connector 30, in a specific embodiment, the end of the first section 11 and the first connector 20 are wound to the second outermost layer, and the end of the second section 12 and the second connector 30 are wound to the outermost layer; when observing along the winding height direction of the double-sided stretching automatic storage magnetic attraction flat wire 100, the first section 11 and the first connector 20 protrude from the second section 12 and the second connector 30.

[0069] It should be noted that in the above solution, by disposing the first section 11 and the first connector 20 in the second outermost layer, by disposing the second section 12 and the second connector 30 in the outermost layer, and making the protruding distance of the first section 11 and the first connector 20 greater than the protruding distance of the second section 12 and the second connector 30, so that after the first section 11 and the first connector 20 are pulled out first, the second section 12 and the second connector 30 can be pulled out. The problem that it is difficult to pull out the second section 12 when the first section 11 is longer than the second section 12 is avoided.

[0070] In the second embodiment, specifically refer to Figures 7-8 , the second section 12 has a third surface 12b disposed opposite to the second surface 12a, the first section 11 and the second section 12 are arranged in parallel and folded, and the first surface 11a and the third surface 12b are in the same plane, so as to wind the first connector 20 and the second connector 30 to the outermost layer.

[0071] It should be noted that in the second embodiment, the folding method of the first section 11 and the second section 12 is changed from folding in half in the first embodiment to side-by-side folding, that is, by folding the second section 12 to one side of the first section 11 and making the sides of the first section 11 and the second section 12 fit together. After the first section 11 and the second section 12 are folded side by side, the first section 11 and the second section 12 are wound together to form a double-wound structure. At this time, the first connector 20 and the second connector 30 are both wound to the outermost circle. Therefore, when the double-sided stretching automatic retractable magnetic flat wire 100 is used, only the first connector 20 and the second connector 30 on the outermost circle need to be pulled out for use, which neither disrupts the wire harness, has a small winding volume, and is also convenient for adsorbing on nearby iron objects.

[0072] Furthermore, in the second embodiment, by folding the first section 11 and the second section 12 side by side, when magnetizing, the first section 11 and the second section 12 are also placed side by side in the magnetizer for magnetization. The specific magnetization method is the same as that of the first embodiment except for the folding method, and details will not be described here.

[0073] Furthermore, when the wire 10 is wound, the double-sided stretching automatic retractable magnetic flat wire 100 includes an adsorption area 100a and a connection area 100b; the adsorption area 100a is located in the inner circle, the connection area 100b is located in the outer circle, and the first connector 20 and the second connector 30 are located in the connection area 100b.

[0074] It should be noted that by setting the adsorption area 100a and the connection area 100b, after the first connector 20 and the second connector 30 are pulled out from the connection area 100b, the double-sided stretching automatic retractable magnetic flat wire 100 can be adsorbed on the electrical equipment (such as the iron part on the chassis, etc.) through the adsorption area 100a.

[0075] Furthermore, the bent section 13 is located in the adsorption area 100a after winding.

[0076] It should be noted that since in this application, when the wire 10 is wound, the first section 11 and the second section 12 are first folded at the bent section 13, therefore, the bent section 13 belongs to the end point after the first section 11 and the second section 12 are folded. Therefore, when folding, the bent section 13 is the starting point of folding and is then folded to the innermost circle of the winding coil, that is, the axis center.

[0077] In a specific embodiment, the double-sided stretching automatic retractable magnetic flat wire 100 is wound to form a circular coil.

[0078] Furthermore, in order to prevent the wound coil from not being adsorbed on the iron part due to magnetic distribution, in a specific embodiment, when observing along the direction perpendicular to the adsorption area 100a, the area where the bent section 13 is located after winding is within the adsorption area 100a.

[0079] In the above solution, the area after the bending section 13 is wound is located within the adsorption area 100a, so that after the first connector 20 and the second connector 30 are pulled out, there are other wire materials 10 in the adsorption area 100a in addition to the bending section 13. Since the wire material 10 is filled with a magnetic material layer, under the action of the magnetism of the magnetic material layer, the adsorption area 100a can still be adsorbed on the ironware, avoiding the problem that the adsorption area 100a cannot be adsorbed because it is all composed of the non-magnetic bending section 13.

[0080] In a specific embodiment, for the convenience of winding the wire material 10, after the bending section 13 is wound, a first winding opening 101a and a second winding opening 101b which are oppositely arranged are formed at the axis of the adsorption area 100a, and the first winding opening 101a and the second winding opening 101b are used for a person's finger or a mechanical device to pass through.

[0081] It should be noted that during the winding process of the wire material 10, generally, the wire material 10 is wound by driving the shaft to rotate by hand or by a motor. In this application, the first winding opening 101a and the second winding opening 101b are provided to facilitate the insertion of a person's hand or a machine shaft, so as to facilitate the winding of the wire material 10.

[0082] The above-provided bidirectional stretching automatic storage magnetic flat wire 100 is folded and arranged with the first section 11 and the second section 12 and then wound together, so that the first connector 20 and the second connector 30 are respectively located in the outermost two circles. When the bidirectional stretching automatic storage magnetic flat wire 100 is in use, the first connector 20 and the second connector 30 can be respectively peeled off from the outermost two circles and connected to corresponding electronic devices. And because the wire material 10 is filled with a magnetic adsorption material, after the first connector 20 and the second connector 30 on the outer circle are peeled off, the wound inner circle can still be adsorbed on the iron shell near the electronic device. It avoids the problem that a connection end of the existing bidirectional stretching automatic storage magnetic flat wire 100 is wound to the inner circle and the wire material 10 is in a mess when being pulled out, and also avoids the problem that it is difficult to adsorb because the inner layer of the coil formed by winding the wire material 10 in a stacked manner forms a three-dimensional shape, thus realizing the problem of being convenient to place and the wire material 10 not being in a mess.

[0083] The above are only the implementation manners of the present application. It should be noted here that for those of ordinary skill in the art, without departing from the creative concept of the present application, improvements can still be made, but these all belong to the protection scope of the present application.
