[0002] The low-voltage distribution network includes overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and ancillary facilities. When emergency repairs are carried out on the low-voltage distribution network, which plays an important role in distributing electric energy in the power grid, emergency repair wires are required, which involves the transportation, deployment and recovery of the wires.

[0003] The current low-voltage distribution network fault repair wire-laying device usually winds the wires at the same position on the drum when in use, causing the wound wires to butt together, so that more butt-jointed wires are embedded in the butt gaps. When the wires need to be laid out again, the embedded wires have great resistance, which affects the wire-laying effect and increases the workload of the staff.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention has multiple wire-releasing mechanisms on the central axis, and the wire-releasing mechanisms include a limit assembly arranged on the central axis, one end of the limit assembly is provided with multiple isolation rods that rotate evenly along the circumferential direction, and the other end is provided with multiple sliding rods that slide, and the sliding rod is away from one end of the limit assembly and is rotatably connected with an elastic rod; a ring is also provided on the limit assembly; and multiple adjustment assemblies are connected to the limit assembly in a uniformly circumferential rotation. During operation, the isolation rod is lifted and the elastic rod is flattened by using the sleeve ring; multiple wire coils are respectively installed on the adjustment components of multiple wire-releasing mechanisms, and then the isolation rod is lowered; the sleeve ring is removed from the elastic rod, and the elastic rod is rotated upward and connected to the isolation rod; the arrangement of multiple limit assemblies and the connection of the elastic rod with the isolation rod enable the wire coils to be separated independently, thus avoiding the problem of multiple wires being embedded together and affecting the wire-releasing effect; at the same time, when the wire is released, the adjustment component rotates relative to the limit assemblies to lower the wire on the wire coil; when the wire is collected, the rotation of the central axis drives the entire limit assembly to rotate, and the wire is wound around the isolation rod and the elastic rod, thus avoiding the contact between the wire and the original wire of the wire coil when collecting the wire, avoiding the influence on the wire, making it easier to release the wire next time, and at the same time avoiding the pollution of the original wire of the wire coil by mud on the wire when collecting the wire, thus ensuring the cleanliness of the original wire of the wire coil.

[0020] 2. The present invention provides a wire-releasing mechanism to form a cage-like space between the sliding rod, the elastic rod and the isolation rod, so that the wire is covered inside, and then the extended end of the wire is pulled out and wound with the buffer component and the guide component to extend out. When in use, the buffer component pulls the wire to make the adjustment component rotate in the space, so as to prevent the wire from loosening and falling off, causing entanglement and knotting, and being difficult to unfold and affecting emergency repair work. After the emergency repair is completed, the excess wire needs to be recovered. Since the wire is stretched and in contact with the ground, the surface is in contact with a large amount of dust and soil. At this time, the guide component will clean the surface of the wire and wind the stretched wire around the outside of the isolation rod and the elastic rod to isolate and store it from the unused wire, so as to prevent dust and moisture from contacting the new wire, causing the new wire to be contaminated, affecting the storage time or causing damage to the wire. At the same time, the stretched part of the wire is dried overhead and wound in a dispersed manner, so as to enhance the cleanliness of this section of the wire, which is conducive to long-term storage, and also to prevent the wire from being wound too tightly for the next use, affecting the construction speed, and facilitating the workers to carry out emergency repair work.

[0021] 3. The present invention can fix wires of different thicknesses by setting a limit component, and can fix and unfold different numbers of wires separately, effectively avoiding the situation where the wires are entangled with each other. The two states of paying out and taking up the wires are completed by fixing with the central axis, and the stretched wires are separated from the unstretched wires, thereby strengthening the storage environment of the wires and making the emergency repair work more convenient and efficient.

[0022] 4. The present invention sets a guiding mechanism, and the wires pass through the limiting ring. Each group of wires is guided, limited and separated to avoid entanglement at the initial end. After the emergency repair is completed, the excess wires need to be recovered, and the central axis drives the wire-releasing mechanism to rotate in the opposite direction to pull the wires back. At this time, the cleaning component simply cleans the outer skin of the wire to avoid excessive soil adhering to the outer skin of the wire, which may pollute the inside of the wire and affect the storage of the wire. When the winding is about to be completed, the telescopic column is extended again to drive the push rod away from the machine. The cleaning component clamps one end of the wire to avoid the wire being scattered due to loose fixation and affecting its use.

[0023] 5. The present invention provides a cleaning component to block the dust on the outer skin of the wire outside the fixing box, clean the surface of the wire, and avoid excessive adhesion of dirt and dust, which would pollute the storage environment of the unused wires. At the same time, the stretched wires are protected to avoid long-term adhesion of debris, which would cause corrosion of the wires and affect their use, resulting in waste. The push rod is used to clamp and fix one end of the wire, which is convenient for the workers to use next time and strengthens the fixation of the wire coil to avoid loosening due to external force, which would cause the wires to be entangled and affect their next use.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0038] Embodiment 1:

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a low-voltage distribution network fault emergency repair wire-laying device, including a machine platform 1, a mounting plate 2, a drive platform 3, a double-headed motor 4, a central axis 5, a wire-laying mechanism 6, a first partition plate 7, a buffer mechanism 8, a guide mechanism 9, a telescopic column 10 and a push rod 11, etc.

[0040] Optionally, there are two mounting plates 2, which are symmetrically arranged at the two ends of the top of the machine 1; the bottom of the mounting plate 2 is rotatably connected to the top of the machine 1 by means of a hinge or a pin. On the machine 1, the central shaft 5 is rotatably arranged at a position between the two mounting plates 2 through a double-headed motor 4 and other components, and the two ends of the central shaft 5 are rotatably connected to the machine 1. The outer surface of the central shaft 5 is evenly provided with first partitions 7, and the protrusions of the first partitions 7 are stuck on the outer surface of the central shaft 5. The double-headed motor 4 is arranged in the middle of the outer surface of the central shaft 5, and the outer wall of the double-headed motor 4 is fixedly connected to the outer wall of the central shaft 5. The bottom of the double-headed motor 4 is fixedly connected to the driving platform 3, and the outer wall of the driving platform 3 is fixedly connected to the outer surface of the machine 1.

[0041] The wire-releasing mechanism 6 is used to fix the wire coil and unfold the wire. The inner wall of the wire-releasing mechanism 6 is sleeved with the outer wall of the central axis 5. Multiple wire-releasing mechanisms 6 are evenly arranged on the central axis 5, and the wire-releasing mechanism 6 and the first partition 7 are staggered. The buffer mechanism 8 is used to cooperate with the wire-releasing mechanism 6 to gather the unfolded wires. The outer surface of the buffer mechanism 8 is rotatably connected to the opposite side of the machine 1, and the height of the buffer mechanism 8 is lower than the wire-releasing mechanism 6. The guide mechanism 9 is used to unfold multiple wires for separate use. Multiple guide mechanisms 9 are evenly arranged on the machine 1. The outer wall of the guide mechanism 9 is fixedly connected to the outer wall of the machine 1, and the bottom of the guide mechanism 9 is fixedly connected to the outer surface of the machine 1. The push rod 11 is provided at one end of the guide mechanism 9 away from the machine 1. The telescopic column 10 is arranged between the push rod 11 and the machine 1. The end of the telescopic column 10 away from the push rod 11 is fixedly connected to the outer wall of the machine 1. The telescopic column 10 can be an electric telescopic rod, a pneumatic telescopic rod, a night-pressed telescopic rod or other forms of telescopic mechanisms. The end of the push rod 11 close to the machine 1 is rotatably connected to the outer wall of the guide mechanism 9.

[0042] When working, the staff first prepares the required wire coils. Initially, the mounting plates 2 on both sides of the machine 1 are in a horizontal state, and the central shaft 5 is supported by the double-headed motor 4. The staff removes the first partition 7. When the protrusion of the first partition 7 is placed vertically, it is engaged with the circular groove of the central shaft 5. After rotating 90 degrees, the protrusion on the first partition 7 can be taken out of the circular groove of the central shaft 5. The first partition 7 is removed, and the wire release mechanism 6 is fixed on the central shaft 5; the number of wire release mechanisms 6 on the central shaft 5 is consistent with the number of coils required. Then the required wire coils are hung on the wire release mechanism 6, and the first partition 7 is installed between every two different wire coils. The unfolded ends of all wires are passed around the buffer mechanism 8 for one circle, and then passed through the inside of the guide mechanism 9. After all the wires are passed through, the telescopic column 10 drives the push rod 11 to move inward to make one end of the wire stuck. When emergency repairs are performed on site, the telescopic column 10 drives the push rod 11 outward to loosen the wire, and the wire-releasing mechanism 6 cooperates with the buffer mechanism 8 to unfold the wire coil. The rotation speed of the buffer mechanism 8 is greater than the speed of use of the staff, which is convenient for the staff to drive the wire to move. After the emergency repairs are completed, the double-headed motor 4 drives the central shaft 5 to rotate, recycles the pulled wire and winds it around the outside of the wire-releasing mechanism 6. When the wire head approaches the guide mechanism 9, the telescopic column 10 contracts again to clamp the wire for the next use.

[0043] In order to achieve the detachability of the first partition 7 on the central axis 5, in some other embodiments, the first partition 7 can also be set as two semicircular plate structures hinged together at one end, and the other ends of the two semicircular plate structures are provided with card interfaces and other components to achieve card connection and release; a semicircular hole is opened in the middle position of the two semicircular plate structures for accommodating the central axis 5.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the line-releasing mechanism 6 includes a limit assembly 601, and the limit assembly 601 includes a sleeve portion sleeved on the central shaft 5, and an annular ear plate arranged at one end of the sleeve portion. The interior of the limit assembly 601 is snap-fitted with the outer wall of the central shaft 5; the isolation rod 602 is evenly arranged on the annular ear plate of the limit assembly 601, and the outer wall of the isolation rod 602 is rotatably connected to the limit assembly 601 through a hinge shaft or other rotational connection method. On the side wall of the annular ear plate of the limit assembly 601, an adjustment assembly 603 is evenly arranged along the circumferential direction near one end of the isolation rod 602, and the outer wall of the adjustment assembly 603 is slidably connected to the inner wall of the limit assembly 601. The line-releasing mechanism 6 also includes a sliding rod 604, and the outer wall of the sliding rod 604 is slidably connected to the end of the limit assembly 601 away from the isolation rod 602. One end of the sliding rod 604 away from the limiting assembly 601 is rotatably connected to the elastic rod 605 through a hinge shaft or other rotatable connection method. One end of the sliding rod 604 away from the elastic rod 605 is rotatably connected to a connecting ring 606. The limiting assembly 601 is also provided with a ring 607.

[0045] When the wire-releasing mechanism 6 is installed on the central shaft 5, the limiting assembly 601 makes the wire-releasing mechanism 6 as a whole stuck with the central shaft 5. At this time, the mounting plate 2 is horizontal, and the sleeve ring 607 is pulled to the end away from the limiting assembly 601 to retract the elastic rod 605, so that the wire coil is sleeved on the adjusting assembly 603. The inner circle of the inserted wire coil contacts the adjusting assembly 603. After the sleeve is inserted, the sleeve ring 607 is moved to the end close to the limiting assembly 601, the sliding rod 604 is moved to make it close to the wire coil and the sliding rod 604 is rotated in the direction of the wire coil to align with the wire. After the circle contacts, the end of the elastic rod 605 is buckled with the end of the isolation rod 602 to form a cage-like space between the sliding rod 604, the elastic rod 605 and the isolation rod 602, and the wire is covered inside. Then the extended end of the wire is pulled out and entangled with the buffer mechanism 8 and extended through the guide mechanism 9. When in use, the buffer mechanism 8 pulls the wire to make the adjustment component 603 rotate in the space to prevent the wire from loosening and falling off, causing entanglement and knotting, making it difficult to unfold and affecting the emergency repair work. After the emergency repair is completed, the excess wire needs to be recovered. At this time, the double-headed motor 4 drives the central axis 5 to rotate in the opposite direction of the wire stretching direction to recover the wire. Since the wire is stretched and in contact with the ground, the surface is in contact with a large amount of dust and dirt. At this time, the guide mechanism 9 will clean the surface of the wire and wind the stretched wire around the outside of the isolation rod 602 and the elastic rod 605 to isolate it from the unused wires for storage, so as to prevent dust and moisture from coming into contact with the new wires, causing the new wires to be contaminated, affecting the storage time or causing damage to the wires. At the same time, the stretched part of the wire is dried overhead and scattered, so as to enhance the cleanliness of this section of the wire, which is conducive to long-term storage. At the same time, it also avoids winding it too tightly for the next use, affecting the construction speed, and facilitating the staff to carry out emergency repairs.

[0046] In other embodiments, Figure 5 and Figure 6 As shown, the limiting component 601 includes a spool 6011, the inner wall of the spool 6011 is socketed with the outer wall of the central axis 5, the outer surface of the spool 6011 is provided with a slideway 6012, the inner wall of the spool 6011 away from the slideway 6012 is evenly provided with slide grooves 6013, the inner wall of the slide groove 6013 is slidably connected to the outer wall of the sliding rod 604, the inner wall of the spool 6011 is provided with a cavity 6014, the inner wall of the spool 6011 is provided with the rotating rod 6016, the outer wall of the rotating rod 6016 is rotatably connected to the inner wall of the spool 6011, and the end of the rotating rod 6016 close to the central axis 5 is fixedly connected with a block 6015, and the outer surface of the block 6015 is in contact with the inner wall of the central axis 5.

[0047] At the beginning, the spool 6011 is sleeved on the central axis 5. A plurality of circular grooves are provided on the central axis 5, and the inner diameter of the grooves is larger than the length of the block 6015. The staff can adjust the distance between the spools 6011 as needed. After reaching the appropriate position, the staff rotates the rotating rod 6016 90 degrees to rotate the block 6015 from a horizontal state to a vertical state, and fixes the spool 6011 to the central axis 5. The sliding rod 604 can slide on the spool 6011. The cavity 6014 facilitates the connection rod to follow the movement of the sliding rod 604, so that the distance between the sliding rod 604 and the wire coil can be adjusted. Wires of different thicknesses can be fixed, and different numbers of wires can be fixed and unfolded separately, effectively avoiding the situation where the wires are entangled with each other. The two states of releasing and retrieving are completed by fixing with the central axis 5, and the stretched wires are separated from the unstretched wires, thereby strengthening the storage environment of the wires and making the emergency repair work more convenient and efficient.

[0048] like Figure 6 As shown, optionally, the adjustment component 603 includes a slider 6031, the outer wall of the slider 6031 is slidably connected to the inner wall of the spool 6011, the end of the slider 6031 away from the slide 6012 is rotatably connected to a U-shaped frame 6032, the top of the U-shaped frame 6032 is evenly fixedly connected to a first spring 6033, and the top of the first spring 6033 is fixedly connected to a buffer frame 6034.

[0049] Before the conductor coil is put on, the U-shaped frame 6032 is in an external tangent state with the outer surface of the spool 6011. After the conductor coil is put on, the U-shaped frame 6032 rotates to make the supporting force of the buffer frame 6034 on the inner circle of the wire relatively vertical, thereby strengthening the support inside the conductor coil and supporting and fixing the conductor coils with different inner circle diameters, which is suitable for supporting different types of conductors. Subsequently, under the pulling of the acceleration roller 801, the U-shaped frame 6032 rotates along the spool 6011 to unfold the wire. When the wire is recovered, the slider 6031 no longer moves, and the wire is recovered and wound around the outside of the isolation rod 602 under the drive of the spool 6011.

[0050] During operation, the spool 6011 is sleeved on the central axis 5. A plurality of circular grooves are provided on the central axis 5, and the inner diameter of the grooves is greater than the length of the block 6015. The staff can adjust the distance between the spools 6011 as needed. After reaching the appropriate position, the staff rotates the rotating rod 6016 90 degrees to rotate the block 6015 from a horizontal state to a vertical state, and fixes the spool 6011 to the central axis 5. The sliding rod 604 can slide on the spool 6011. The cavity 6014 facilitates the connection rod to follow the movement of the sliding rod 604, so that the distance between the sliding rod 604 and the wire coil can be adjusted. Before the wire coil is sleeved, the U-shaped frame 6032 and the outer surface of the spool 6011 are in an externally tangent state. After the wire coil is sleeved, the U-shaped frame 6032 rotates to make the support force of the buffer frame 6034 on the inner coil of the wire relatively vertical, thereby strengthening the support inside the wire coil. The support is used to support and fix the wire coils with different inner diameters, and is suitable for different types of wire supports. Subsequently, under the pulling of the accelerating roller 801, the U-shaped frame 6032 is rotated along the bobbin 6011 to unfold the wire. When the wire is recovered, the slider 6031 no longer moves. Driven by the bobbin 6011, the wire is recovered and wound around the outside of the isolation rod 602. When the wire is recovered, a rubber block with a relatively soft texture is placed inside the fixed box 9063. When the wire is stretched, the L-shaped rod 9064 is driven by the built-in power system to move outward along the slide on the fixed box 9063. The inside of the L-shaped rod 9064 contacts the inside of the rubber block, and the inner circle of the rubber block is opened by the movement of the L-shaped rod 9064 to facilitate the rapid passage of the wire. When the wire is recovered, the L-shaped rod 9064 automatically returns to its original position, contacts the inside of the rubber block with the outer wall of the wire, and blocks the dust outside the wire outside the fixed box 9063.

[0051] like Figure 7As shown, the buffer mechanism 8 includes an accelerating roller 801, the outer wall of which is rotatably connected to the opposite side of the machine 1. Optionally, the accelerating roller 801 may include a motor and a rotating shaft, the motor being arranged on the machine 1, and the rotating shaft being connected to the output shaft of the motor. The rotating shaft of the accelerating roller 801 is fixedly connected with the telescopic rod 802, the telescopic rod may be an electric telescopic rod, a pneumatic telescopic rod, etc., the end of the telescopic rod 802 away from the machine 1 is fixedly connected with the baffle 803, the end of the baffle 803 away from the telescopic rod 802 is fixedly connected with the sleeve 804, the inner wall of the sleeve 804 is sleeved with the outer surface of the accelerating roller 801, the outer surface of the accelerating roller 801 is evenly provided with the second partition 805, the second partition 805 is used to separate the wires from each other to avoid entanglement when multiple wires are used, and the inner wall of the second partition 805 is fixedly connected with the outer wall of the accelerating roller 801. When in use, the acceleration roller 801 rotates at a relatively fast speed. While the acceleration roller 801 drives the telescopic rod 802 and the sleeve 804 to rotate, the telescopic rod 802 retracts and retracts back and forth, and arranges the wires stretched out from the wire coil in sequence on the sleeve 804, thereby reducing the resistance of the staff during the stretching process.

[0052] like Figure 8 As shown, optionally, the guide mechanism 9 includes a mounting seat 901, the outer wall of the mounting seat 901 is fixedly connected to the outer wall of the machine 1, the mounting seat 901 is symmetrically arranged with the machine 1 as the center, the top of the mounting seat 901 is fixedly connected to a support rod 902, the outer surface of the support rod 902 is evenly provided with the moving ring 903, and the inner wall of the moving ring 903 is fixedly connected to the outer surface of the support rod 902. The bottom of the moving ring 903 is fixedly connected to the limit ring 904, the bottom of the limit ring 904 is fixedly connected to the counterweight plate 905, the bottom of the counterweight plate 905 is fixedly connected to the outer surface of the machine 1, and the cleaning assembly 906 is arranged at one end of the counterweight plate 905 far from the limit ring 904. The outer surface of the cleaning component 906 is slidably connected to the outer surface of the counterweight plate 905 by means of a slide groove or the like; a second spring 907 is fixedly connected to the bottom of the cleaning component 906, and the bottom of the second spring 907 is fixedly connected to the outer surface of the machine 1; a support rod 908 is provided at one end of the bottom of the cleaning component 906 away from the second spring 907, and the top of the support rod 908 is rotatably connected to the bottom of the cleaning component 906 by means of a hinge or the like, and the bottom of the support rod 908 is slidably connected to the outer surface of the machine 1 by means of a slide groove or the like, and the end of the support rod 908 away from the cleaning component 906 is rotatably connected to the outer wall of one end of the push rod 11 close to the machine 1.

[0053] Before use, after the staff has installed the required wires in sequence, the telescopic column 10 is retracted and extended to drive the push rod 11 away from the machine 1, thereby driving the cleaning component 906 to lose the support of the support rod 908, and the cleaning component 906 falls rapidly under the drive of the second spring 907 to clamp the wire between the cleaning component 906 and the limit ring 904, so that one end of the wire is stuck on the machine 1 to prevent the wire head from being loose due to unfixed wire head. When in use, the telescopic column 10 is retracted to drive the support rod 908 close to the cleaning component 906 to support it. The wires pass through the limit ring 904, and each group of wires is guided and limited to separate to avoid them from being entangled at the initial end. After the emergency repair is completed, the excess wires need to be recovered, and the central axis 5 drives the wire-releasing mechanism 6 to rotate in the opposite direction to pull the wires back. At this time, the cleaning component 906 simply cleans the outer skin of the wire to avoid excessive soil adhering to the outer skin of the wire, which may pollute the inside of the wire and affect the storage of the wire. When the winding is about to be completed, the telescopic column 10 is extended again, driving the push rod 11 away from the machine 1, and the cleaning component 906 clamps one end of the wire to avoid the wire being loosely fixed and causing dispersion, which affects its use.

[0054] The specific workflow is as follows:

[0055] When working, the staff first performs preparation work and prepares the required wire coils. Initially, the mounting plates 2 on both sides of the machine 1 are in a horizontal state, and the central axis 5 is supported by the double-headed motor 4. The staff removes the first partition 7 and fixes the wire-releasing mechanism 6 on the central axis 5. The number of wire-releasing mechanisms 6 on the central axis 5 is consistent with the number of coils required. Then, the required wire coils are hung on the wire-releasing mechanism 6, and the first partition 7 is installed between every two different wire coils. Then, the unfolded ends of all the wires are passed around the buffer mechanism 8 for one circle, and then passed through the inside of the guide mechanism 9. All the wires are After the wire is passed through, the telescopic column 10 drives the push rod 11 to push outward to jam one end of the wire. When emergency repair work is carried out on site, the telescopic column 10 drives the push rod 11 to push outward to relax the wire, and the wire-releasing mechanism 6 cooperates with the buffer mechanism 8 to unfold the wire coil. The rotation speed of the buffer mechanism 8 is greater than that of the wire-releasing mechanism 6, which is convenient for the staff to drive the wire to move. After the emergency repair work is completed, the double-headed motor 4 drives the central axis 5 to rotate, recycles the pulled-out wire and winds it around the outside of the wire-releasing mechanism 6. When the wire head is about to approach the guide mechanism 9, the telescopic column 10 extends outward again to jam the wire for easy use next time.

[0056] like Fig. 9As shown, the cleaning assembly 906 includes a movable plate 9061, the outer wall of the movable plate 9061 is slidably connected to the outer surface of the counterweight plate 905, the top of the movable plate 9061 is fixedly connected to a round rod 9062, the top of the round rod 9062 is fixedly connected to the fixed box 9063, the L-shaped rod 9064 is evenly arranged at one end of the fixed box 9063 close to the limiting ring 904, and the inner wall of the L-shaped rod 9064 is slidably connected to the outer surface of the fixed box 9063 by means of a slide groove or the like.

[0057] A relatively soft rubber block is placed inside the fixed box 9063. When the wire is stretched, the L-shaped rod 9064 is driven by an internal pre-set power system, which can be a linear motor or an electric telescopic rod, etc. The L-shaped rod 9064 moves outward along the slide on the fixed box 9063, and the inside of the L-shaped rod 9064 contacts the inside of the rubber block, and the inner circle of the rubber block is opened by the movement of the L-shaped rod 9064, so that the wire can pass quickly. When the wire is recovered, the L-shaped rod 9064 automatically returns to its position, contacts the inside of the rubber block with the outer wall of the wire, and blocks the dust on the outer skin of the wire outside the fixed box 9063, cleans the surface of the wire to prevent excessive adhesion of mud and dust, which pollutes the storage environment of unused wires, and protects the stretched wire to prevent long-term adhesion of debris, which may cause corrosion of the wire and affect its use, resulting in waste. In addition, the push rod 11 is used to clamp and fix one end of the wire, which is convenient for the staff to use next time and strengthens the fixation of the wire coil to prevent it from loosening due to external force shaking, causing the wire to be entangled and affecting the next use.
