Description

Technical Field

[0001] This invention relates to the field of cable equipment technology, and more particularly to a winding device and its usage method. Background Technology

[0002] Before installing cables for urban rail vehicles, the cables should be unloaded and then coiled for storage. After unloading, the cables are generally coiled and stored manually. They are coiled and categorized according to their length and diameter for later use.

[0003] Urban rail vehicles' high-voltage cables and undercarriage cables are large in diameter, long in length, and heavy. Most low-voltage and medium-high-voltage cables on urban rail vehicles are through-wires, with many exceeding 10 meters in length. After unloading, the cables are manually coiled. Manually coiling long cable bundles is time-consuming and inefficient. Furthermore, manually coiling heavy cables after unloading is inconvenient and reduces work efficiency. Summary of the Invention

[0004] In response to the aforementioned technical problems, a winding device and its usage method are provided.

[0005] The technical means employed in this invention are as follows:

[0006] A winding device includes: a retractable arm structure, a support device, and a drive device mounted on the support device. The retractable arm structure includes a connected hand crank and multiple retractable arms arranged in a circle. The hand crank is used to retract or unfold the multiple retractable arms. The output end of the drive device is connected to the retractable arm structure and is used to drive the retractable arm structure to rotate with the retractable arms in the unfolded state to wind the cable. The cable can be removed by retracting the retractable arms driven by the hand crank.

[0007] Furthermore, the retractable arm structure also includes a threaded connecting rod, a screw base, multiple limiting cantilever structures, a fastening bolt assembly, and a disc. The hand crank includes a threaded rod, the external thread on the outer wall of the threaded rod being threadedly connected to the internal thread on the inner wall of the threaded connecting rod. The lower end of the threaded connecting rod is connected to the screw base via the fastening bolt assembly, and the driving device is connected to the bottom of the threaded connecting rod. The disc is fitted into the cylindrical surface at the upper end of the threaded rod. The upper parts of the multiple retractable arms are hinged to the disc, and the lower parts of the multiple retractable arms are slidably connected to the multiple limiting cantilever structures. The limiting cantilever structures are installed at the connection between the threaded connecting rod and the screw base.

[0008] Furthermore, the limiting cantilever structure includes a ball head, a fastening nut, and a movable rod. The connection between the threaded connecting rod and the screw base has multiple splicing holes in the circumferential direction. The ball head is embedded in the splicing hole. The outer wall of the root of the ball head has an external thread. The fastening nut is threaded to the external thread of the root. The root has an installation hole. The inner wall of the installation hole has an internal thread. The external thread at one end of the movable rod is threaded to the internal thread of the installation hole. The other end of the movable rod is suspended.

[0009] Furthermore, the retractable arm includes a support arm, a square steel bar, and an outer arm. The upper end of the support arm is hinged to the disc, and the lower end is connected to the square steel bar. The outer arm is connected to the square steel bar and is set at an angle to the support arm. A through circular hole is provided inside the square steel bar for the movable rod of the cantilever structure to pass through.

[0010] Furthermore, the angle between the support arm and the outer arm is less than 90 degrees.

[0011] Furthermore, a V-shaped wire-locking mold is provided on the outer side of any one of the plurality of retractable arms for locking the wire.

[0012] Furthermore, a connecting seat is welded to the bottom of the disk, and the connecting seat is hinged to the retractable arm via a pin structure; the diameter of the disk is larger than the diameter of the cylindrical surface and smaller than the diameter of the threaded rod.

[0013] Furthermore, the hand crank also includes a top plate and a handle. The top of the threaded rod is fixedly connected to the center of the top plate, and the handle is fixed on the top plate, located above the threaded rod and eccentrically positioned relative to the handle.

[0014] Furthermore, the driving device includes a rotary motor, the supporting device includes a support frame, the support frame includes an upper plate, a protective cover and a bottom frame structure, the bottom frame structure is equipped with a power supply box and a foot switch, the upper plate is installed on the top of the bottom frame structure, the protective cover is installed on the outer edge of the upper plate, the rotary motor is installed below the upper plate through a cover plate and multiple fixing bolts, the rotor extending from the rotary motor is connected to the threaded connecting rod of the retractable arm structure, and the rotary motor drives the retractable arm structure to rotate.

[0015] The present invention also provides a method of using a winding device, comprising the following steps:

[0016] Step 1: Before use, along the direction of rotation of the rotary motor, use the hand crank to move the disc downwards and unfold the retractable arm, and then press the disc to fix it in place. As the hand crank moves the disc downwards, the threaded rod of the hand crank goes deeper into the threaded connecting rod, and the distance between the lower plane of the top plate of the hand crank and the upper plane of the threaded connecting rod gradually decreases, thereby pressing the disc to fix it in place. During the downward movement of the disc, the retractable arm changes from a retracted state to an unfolded state.

[0017] Step 2: Use the V-shaped wire clamping die to clamp the cable end, and use the foot switch to control the start and stop of the rotary motor; during the start of the rotary motor, the threaded connecting rod is driven to rotate, and the threaded connecting rod transmits the rotational power to the threaded rod of the hand crank and the coiling arm to coil the cable. When coiling the cable, the cable is clamped at the V-shaped wire clamping die and coiled along the outer arm of the coiling arm.

[0018] Step 3: After coiling the cable, use the hand crank to rotate in the opposite direction to move the coiling arm upward. The limiting cantilever structure follows and continues to support the coiled cable. After the coiling arm coils, the cable changes from taut to slack, and the cable can be removed. The coiling process is as follows: when the hand crank is rotated to move the coiling arm upward, the pin structure at the upper end of the coiling arm causes the support angle of the coiling arm to change. The limiting cantilever structure follows the change in the support angle of the coiling arm and moves upward to continue supporting the coiled cable. During the upward coiling process, on the outside of the coiling arm, at the same height position on the same circumference, the circumference of the coiling arm decreases, the coiled cable changes from a taut state to a slack state, the limiting cantilever structure tilts upward, and continues to support the coiled cable.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. This invention uses a winding device to wind and coil cables of different diameters and lengths, thereby improving production efficiency and facilitating production operations.

[0021] 2. This invention relates to a winding device with a retractable arm. The winding device is equipped with a motor for rotating the coiled cable, a hand crank for controlling the extension and retraction of the retractable arm, and a V-shaped cable clamping mold fixedly installed on the retractable arm to clamp the cable. The retractable arm has a limiting cantilever structure to support the coiled cable. A power supply box and a foot switch are installed at the bottom to control the motor's start and stop. In use, first, the hand crank is used to drive the disc to move the retractable arm of the winding device downwards, unfold it, and press the disc to fix it. The cable is clamped onto the V-shaped cable clamping mold. The power is turned on and the foot switch is stepped on. The retractable arm rotates to coil the cable. After the cable is coiled, the hand crank is used to drive the disc to move the retractable arm of the winding device upwards to retract it, and the coiled cable is removed.

[0022] Based on the above reasons, this invention can be widely applied in fields such as wire coiling. Attached Figure Description

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0049] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0050] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0051] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0053] This invention provides a winding device that uses a limiting cantilever to achieve cable coiling. A rotary motor drives the coiling arm structure to rotate, and the main components, including a V-shaped cable clamp, the coiling arm, and the limiting cantilever structure, are used to coil the cable. A hand crank is used to unwind and rewind the coiled cable. This process is novel, innovative, and practical.

[0054] This invention relates to a winding device with a retractable arm. The device includes a motor for rotating the coiled cable, a hand crank for controlling the extension and retraction of the retractable arm, and a V-shaped cable clamping mold fixedly mounted on the retractable arm for securing the cable. The retractable arm also features a limiting cantilever structure to support the coiled cable. A power supply box and a foot switch are installed at the bottom to control the motor's start and stop. In use, the hand crank is first used to move the retractable arm downwards and unfold it, then presses the disc to secure it. The cable is then clamped onto the V-shaped cable clamping mold. The power is turned on, and the foot switch is pressed. The retractable arm rotates to coil the cable. After coiling, the hand crank is used to move the retractable arm upwards to retract it, and the coiled cable is then removed.

[0055] The winding device of this invention can wind and coil cables of different diameters and lengths, thereby improving production efficiency and facilitating production operations.

[0056] like Figure 1 As shown, the winding device of the present invention consists of two main parts: a movable retractable arm structure 1 at the top and a motor and support frame 4 at the bottom. The motor and support frame 4 are connected by a cover plate 2 and fixing bolts 3. The movable retractable arm structure 1 is connected to the motor rotor by threads.

[0057] like Figure 2 As shown, the retractable arm structure 1 consists of a hand crank handle 11, a threaded connecting rod 12, a screw base 13, a retractable arm 14, a limiting cantilever structure 15, a V-shaped wire clamping mold 16, a fastening bolt assembly 17, a pin structure 18, and a disc 19.

[0058] like Figure 3-4 As shown, the limiting cantilever structure 15 consists of a ball head 151, a fastening nut 152, and a movable rod 153.

[0059] In the retractable arm structure 1 of the winding device, a hand crank 11 is welded to a disc 19 with a connecting seat welded to its bottom, which is then fitted into the upper cylindrical surface of the threaded rod 111 of the hand crank 11. The diameter of the disc 19 should be slightly larger than the diameter of the cylindrical surface but smaller than the diameter of the threaded rod 111 of the hand crank 11. This ensures that when the hand crank 11 moves the disc 19 upward, the retractable arm 14 is hinged to the connecting seat at the bottom of the disc 19, thus achieving the retracting process of the winding device. When the hand crank 11 moves the disc 19 downward, as the threaded rod 111 of the hand crank 11 continues to penetrate deeper into the threaded connecting rod 12, the distance between the lower plane of the top plate 112 of the hand crank 11 and the upper plane of the threaded connecting rod 12 gradually decreases, thus pressing and fixing the disc 19. During the downward movement of the disc 19, the retractable arm 14 changes from a retracted state to an unfolded state.

[0060] The disc 19 connecting seat is hinged to the retractable arm 14 via a pin structure 18. The hand crank 11 and the threaded connecting rod 12 are fixedly connected by threads. The bottom of the threaded connecting rod 12 is threadedly connected to the motor rotor to achieve winding rotation.

[0061] The threaded connecting rod 12 and the screw base 13 are fixed by the fastening bolt assembly 17. Before fixing, the ball head 151 of the limiting cantilever structure 15 is installed into the splicing hole of the threaded connecting rod 12 and the screw base 13, and fixed by the fastening nut 152 of the limiting cantilever structure 15. The movable rod 153 of the limiting cantilever structure 15 is then passed through the round hole of the square steel 142 of the retractable arm 14.

[0062] The ball head 151 of the limiting cantilever structure 15 is embedded in the splicing hole of the threaded connecting rod 12 and the screw base 13. The diameter of the ball head 151 of the limiting cantilever structure 15 is slightly larger than the outer hole. The ball head 151 is connected to the fastening nut 152 and the movable rod 153. The diameter of the round hole of the square steel 142 of the retractable arm 14 should be slightly larger than the diameter of the movable rod 153 of the limiting cantilever structure 15, so as to ensure that the limiting cantilever structure 15 can move a certain distance in the vertical direction when the hand crank handle 11 is operated, so as to ensure that the retractable arm 14 can retract.

[0063] like Figure 5 As shown, during the coiling process: when the hand crank 11 rotates, causing the coiling arm 14 to move upward, the upper pin structure 18 of the coiling arm 14 causes the angle of the support arm 141 of the coiling arm 14 to change. The limiting cantilever structure 15 follows the change in the angle of the support arm 141 of the coiling arm 14 and moves upward, continuing to support the coiled cable 5. During the upward coiling process of the coiling arm 14, on the outside of the coiling arm 14, at the same circumferential position (at the same height), the circumference of the coiling arm 14 decreases, and the coiled cable changes from a taut state to a slack state. The limiting cantilever structure 15 tilts upward and continues to support the coiled cable. The coiled cable changes from a taut state to a slack state.

[0064] A V-shaped cable clamping mold 16 is provided on the outer side of any one of the retractable arms 14 for clamping the cable. The V-shaped cable clamping mold 16 is connected to the outer arm 143. The V-shaped cable clamping mold 16 increases the friction between the cable and the coiling post, allowing for the clamping of cables of different diameters, thereby achieving precise and rapid cable coiling. Figure 6 As shown:

[0065] like Figure 7 As shown, the motor and support frame 4 consists of a support frame 41, a rotary motor 42, a power supply box 43, and a foot switch 44.

[0066] The winding device is equipped with a support frame 41. An upper protective cover on the support frame 41 protects the operator's safety, while the bottom frame structure supports the rotary motor 42 and houses the power supply box 43 and foot switch 44. The rotary motor 42 is connected to the support frame 41 via a cover plate 2 and fastening bolts 3. The rotor extending from the upper end of the rotary motor 42 is connected to a threaded connecting rod 12. The rotary motor 42 drives the retractable arm structure 1 to rotate.

[0067] Instructions for use: Before use, along the rotation direction of the rotary motor 42, use the hand crank 11 to move the disc 19 downwards and unfold the coiling arm 14 of the winding device, then press and fix the disc 19. Use the V-shaped wire clamp 16 to clamp the cable end, and use the foot switch 44 to control the start and stop of the rotary motor 42. During the start-up process of the rotary motor 42, it drives the threaded connecting rod 12 to rotate. The threaded connecting rod 12 transmits the rotational power to the threaded rod 111 of the hand crank 11 and the coiling arm 14 for winding the cable. During winding, the cable is clamped at the V-shaped wire clamp 16 and wound along the outer arm 143 of the coiling arm 14. After winding, use the hand crank 11 to rotate in the opposite direction to move the coiling arm 14 upwards. The limiting cantilever structure 15 follows and moves upwards to continue supporting the winding of the cable. After the coiling arm 14 coils, the cable changes from taut to slack, and the cable can be removed. Figure 8 As shown.

[0068] Example 1

[0069] First, based on the length and diameter of the cable to be coiled, fabricate the disc 19 and the coiling arm 14, as follows: Figure 9 As shown, the disc 19 is made of Q235B material. The opening size should be larger than the diameter of the upper cylindrical surface of the threaded rod 111 of the hand crank handle 11 and smaller than the thread diameter of the threaded rod 111 of the hand crank handle 11. The thickness of the disc 19 should be smaller than the height of the upper cylindrical surface of the threaded rod 111 of the hand crank handle 11. Six sets of mounting seats with mounting holes are welded to the bottom of the disc 19. The mounting holes should be consistent with the pin holes at the top of the support arm 141 of the retractable arm 14. The diameter of the disc 19 should be at least larger than the maximum dimension between the relative positions of the bottom mounting seats.

[0070] The retractable arm 14 is a welded structure, consisting of 6 sets. Each set of retractable arms 14 comprises a support arm 141, an outer arm 143, and a square steel bar 142 with a round hole. The angle between the support arm 141 and the outer arm 143 should preferably be less than 90 degrees. The vertical height of the outer arm 143 should be set to ensure that the corresponding wire diameter harness can be coiled 15-20 times. To ensure strength, the overall height of the retractable arm 14 should be greater than twice the vertical height of the outer wall 143 of the retractable arm. The retractable arm 14 is a welded steel structure made of Q235B material. The entire retractable arm 14 has six sets of support arms 141. The top of the support arm 141 has a pin hole, and the diameter of the pin hole is consistent with the diameter of the mounting seat hole. The six sets of support arms 141 are fixed to the mounting seat at the lower end of the disc 19 by the pin structure 18. The diameter of the pin of the pin structure 18 should be slightly smaller than the hole diameter to ensure that the six sets of support arms 141 of the retractable arm 14 can be hinged to the disc 19. The bottom of the retractable arm 14 is welded with six square steel bars 142 with round holes. The diameter of the round holes should be slightly larger than the diameter of the movable rod 153 of the limiting cantilever structure 15.

[0071] The hand crank handle 11 is made of Q235B material and is assembled from three parts: a threaded rod 111, a top plate 112, and a handle 113. Before welding, the disc 19 is fitted into the threaded rod 111. The length of the threaded rod 111 should be sufficient to allow for smooth connection with the bottom threaded connecting rod 12. The thread specification should match the specification of the threaded connecting rod 12. A cylindrical surface is reserved at the top of the threaded rod 111, with a diameter slightly smaller than that of the threaded rod 111 and a height slightly greater than that of the disc 19. Figure 10 As shown. After the hand crank handle 11 is welded together, it is connected to the retractable arm 14 via a pin hinge. The six retractable arms 14 are then connected to the six mounting seats at the bottom of the disc 19, as shown. Figure 11 As shown.

[0072] Fabricate threaded connecting rod 12 and screw base 13. The threaded connecting rod 12 and screw base 13 have the following shapes: Figure 12 , 13 As shown. The threaded connecting rod 12 and the screw base 13 are also made of rigid material. Three corresponding circular holes are made at 180-degree intervals on the upper and lower planes of the threaded connecting rod 12 and the screw base 13 for connecting them. The screw base 13 has a central hole with a diameter larger than the outer diameter of the motor rotor to ensure connection between the bottom motor rotor and the threaded connecting rod 12. The threaded connecting rod 12 is threaded internally, with the thread specification matching the hand crank handle 11 and the motor rotor thread specification. Six semi-circular holes are made around the perimeter of both the threaded connecting rod 12 and the screw base 13, spaced at 60-degree intervals. After splicing, six circular holes should remain around the circumference. The length of the threaded connecting rod 12 should ensure that the limiting cantilever structure 15 can directly connect to the circular hole of the square steel 142 of the retractable arm 14 through the hole and can extend a length to carry the cable reel.

[0073] Fabrication of steel limiting cantilever structure 15, see Figure 14 Before the threaded connecting rod 12 and the screw base 13 are fixed by the fastening bolt assembly 17, the ball head 151 of the limiting cantilever structure 15 is embedded in the round hole. The diameter of the ball head 151 is slightly larger than the diameter of the hole, and the position of the ball head 151 at the end of the hole should be slightly smaller than the diameter of the hole to ensure that the limiting cantilever movable rod 153 can move within a certain range. The ball head 151 is threaded internally and externally at its root, and a fastening nut 152 is installed at the external thread to ensure that the ball head 151 cannot come out of the hole. The movable rod 153 is connected and fastened at the internal thread of the ball head 151. The length of the movable rod 153 should be sufficient to pass through the round hole of the retractable arm square steel 142 and extend a certain length to ensure support for the wire harness when the winding device coils the wire. The diameter of the movable rod 153 should be slightly smaller than the diameter of the round hole of the retractable arm square steel 142 to ensure that the movable rod 153 has a certain displacement adjustment range during the retracting process. Figure 14 As shown.

[0074] Make support frame 41, shaped like... Figure 15 As shown, the support frame 11 has a central opening at the top, the size of which should be large enough for the motor rotor to pass through. The support frame 41 is made of steel, with a central circumferential opening at the top, and a corresponding opening cover plate 2 and fastening bolt assembly are made there. The opening size should match the external fixing dimensions and specifications of the motor. A square steel crossbeam is welded to the bottom of the support frame 41 for placing the power supply box 3 and the foot switch 44.

[0075] Select a rotary motor with a suitable winding speed, such as 42. Figure 16 As shown, the rotor thread specification of the rotary motor 42 should match the specification of the threaded connecting rod 12. The outer casing of the rotary motor 42 is provided with fixing bolts 3. The rotary motor 42 is fixed to the bottom of the support frame 41 from the upper support frame 41 through the cover plate 2 by fixing bolts 3.

[0076] This invention utilizes a winding device to wind and coil cables of different diameters and lengths, thereby improving production efficiency and facilitating production operations.

[0077] The protected points of this invention are: 1. a limiting cantilever structure; 2. a process method for curling using the limiting cantilever structure; 3. a method for clamping cables using a V-shaped wire clamping mold (the V-shaped wire clamping mold can clamp cables of any diameter).

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

7. A method of using the winding device as described in claim 6, characterized in that, Includes the following steps: Step 1: Before use, along the rotation direction of the rotary motor (42), use the hand crank (11) to drive the disc (19) to move the retractable arm (14) downward and unfold it, and press the disc (19) to fix it. When the hand crank (11) drives the disc (19) downward, as the threaded rod (111) of the hand crank (11) continues to penetrate into the threaded connecting rod (12), the distance between the lower plane of the top plate (112) of the hand crank (11) and the upper plane of the threaded connecting rod (12) gradually decreases, thereby pressing the disc (19) to fix it. During the downward movement of the disc (19), the retractable arm (14) changes from a retracted state to an unfolded state. Step 2: Use the V-shaped wire clamping mold (16) to clamp the end of the cable (5), and use the foot switch (44) to control the start and stop of the rotary motor (42); during the start of the rotary motor (42), it drives the threaded connecting rod (12) to rotate, and the threaded connecting rod (12) transmits the rotational power to the threaded rod (111) of the hand crank handle (11) and the coiling arm (14) to coil the cable. When coiling the cable, the cable (5) is clamped at the V-shaped wire clamping mold (16) and coiled along the outer arm (143) of the coiling arm (14); Step 3: After coiling the cable, use the hand crank (11) to rotate in the opposite direction to move the coiling arm (14) upward. The limiting cantilever structure (15) follows and moves upward, continuing to support the coiled cable (5). After the coiling arm (14) coils, the cable (5) changes from taut to slack, and the cable (5) is removed. The coiling process is as follows: when the hand crank (11) rotates and moves the coiling arm (14) upward, the pin structure (18) at the upper end of the coiling arm (14) drives the support arm (14) of the coiling arm (14) to move upward. 141) When the angle changes, the limiting cantilever structure (15) moves upward following the angle change of the support arm (141) of the coiled arm (14) and continues to support the coiled cable (5); during the upward coiling process of the coiled arm (14), the circumference of the coiled arm (14) at the same height position on the same circumference outside the coiled arm (14) decreases, the coiled cable (5) changes from a taut state to a slack state, the limiting cantilever structure (15) tilts upward and continues to support the coiled cable (5).
