Description

Technical Field

[0001] This application relates to the technical field of cable production, and in particular to a cable aluminum-plastic composite tape longitudinal wrapping device. Background Technology

[0002] The cable composite tape longitudinal wrapping device is a device specifically designed to longitudinally wrap composite tape around the surface of cables, thereby giving the cables waterproof and self-protective functions.

[0003] The existing composite tape longitudinal wrapping device mainly includes a wire feeding mechanism, a tape releasing mechanism, a wrapping mechanism, and a heating mechanism. The wire feeding mechanism is mainly used to feed the cable into the wrapping mechanism, the tape releasing mechanism is mainly used to feed the composite tape into the wrapping mechanism, and then the wrapping mechanism bends the composite tape into a tubular shape and wraps it around the surface of the cable. Finally, the heating mechanism heats the composite tape wrapped around the surface of the cable so that the composite tape adheres better to the surface of the cable.

[0004] However, in the above process, the heating mechanism usually heats the composite tape wrapped around the surface of the cable using a flame gun, hot air gun, or heating tube. After the wrapping mechanism wraps the composite tape around the surface of the cable, some gas may still remain on the composite tape and the cable surface. When the heating mechanism heats the composite tape to make it adhere tightly to the surface of the cable, the remaining gas may cause bubbles to form on the composite tape wrapped around the cable surface. During subsequent processing, the bubbles may burst, resulting in the cable being exposed, which in turn reduces the production quality of the product. Summary of the Invention

[0005] The purpose of this application is to provide a cable aluminum-plastic composite tape longitudinal wrapping device, which can minimize the appearance of air bubbles on the surface of the composite tape wrapped around the cable, thereby avoiding the situation where the cable is exposed due to the rupture of air bubbles, and thus improving the production quality of the product.

[0006] The cable aluminum-plastic composite tape longitudinal wrapping device provided in this application adopts the following technical solution:

[0007] frame;

[0008] A wrapping mechanism, mounted on the frame, is used to wrap the composite tape around the cable;

[0009] A cable feeding mechanism, located on one side of the frame, is used to feed the cable into the sheathing mechanism;

[0010] A tape feeding mechanism, mounted on the frame, is used to feed the composite tape into the covering mechanism;

[0011] The heating mechanism includes a fixed base and heating silicone. The fixed base is mounted on the frame, and the heating silicone is mounted on the fixed base. The heating silicone is coaxially sleeved on the cable wrapped with composite tape, and the heating silicone does not abut against the composite tape on the cable.

[0012] A shrinking assembly, mounted on the mounting base, is used to shrink the diameter of the inner hole of the heating silicone until the heating silicone abuts against the composite tape on the cable.

[0013] Optionally, the shrinkage assembly includes an air pump mounted on the fixed base, with a sealed space between the outer peripheral wall of the heated silicone and the fixed base, and the output end of the air pump communicating with the sealed space.

[0014] Optionally, the outer peripheral wall of the heated silicone is provided with a plurality of micropores, which extend to the contact point between the heated silicone and the composite tape.

[0015] Optionally, the diameter of the inner hole of the heated silicone gradually decreases from the middle part to both sides.

[0016] Optionally, the frame is also provided with a positioning mechanism, which positions the cables located on both sides of the heating mechanism section to prevent the cables from shaking.

[0017] Optionally, the positioning mechanism includes two sets of positioning wheels, one set of positioning wheels is located on one side of the heating mechanism and between the heating mechanism and the covering mechanism, and the other set of positioning wheels is located on the side of the heating mechanism away from the covering mechanism.

[0018] Optionally, each set of positioning wheels has two wheels, both of which are rotatably mounted on the frame. The two positioning wheels are arranged opposite each other, and the cable passes between the two positioning wheels, with the outer peripheral wall of the positioning wheel abutting against the outer peripheral wall of the cable.

[0019] Optionally, one of the positioning wheels in a set of positioning wheels located in the heating mechanism and the wrapping mechanism abuts against the splice of the composite tape on the cable.

[0020] Optionally, a set of positioning wheels located on the side of the heating mechanism away from the coating mechanism is connected to a driving component. The driving component can drive the set of positioning wheels to rotate around itself, so as to move the coated cable away from the coating mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. After the wrapping mechanism wraps the composite tape around the cable, as the cable continues to move, the cable wrapped with the composite tape moves into the heated silicone. The shrinking assembly is then immediately activated, causing the heated silicone to shrink until its inner hole presses tightly against the composite tape on the cable. This allows the composite tape to adhere tightly to the cable surface. Simultaneously, the heat emitted by the heated silicone softens the composite tape, allowing it to adhere to the cable surface, thus improving the overall connection strength between the cable and the composite tape. As the cable continues to move, and because the heated silicone is constantly shrinking, it presses the composite tape firmly against the cable surface. Therefore, the air between the cable and the composite tape is squeezed out by the heated silicone in the opposite direction of the cable's movement. With less air between the cable and the composite tape, the probability of air bubbles appearing on the surface of the cable wrapped with the composite tape is greatly reduced when the composite tape softens and adheres to the cable surface. This minimizes the risk of air bubble breakage leading to exposed cable, thereby improving cable production quality.

[0023] 2. Before starting the shrink assembly to shrink the heated silicone, the shrink assembly can be started after part of the composite tape on the cable has passed through the heated silicone. This allows the heated silicone to tightly press the composite tape onto the surface of the cable, thus minimizing the risk of the ends of the composite tape wrapped around the cable surface being squeezed by the heated silicone and peeling off the cable surface. This situation often occurs when replacing new composite tape. Therefore, with the design of this shrink assembly and heated silicone, this equipment can avoid the occurrence of the above situation, greatly improving the practicality of the equipment.

[0024] 3. In this embodiment, the shrinkage component uses negative pressure to shrink the heated silicone. The micropores on the rubber allow the heated silicone to shrink rapidly and significantly, applying greater pressure to the composite tape. This results in a tighter bond between the composite tape and the cable surface, further improving the connection strength. The tighter the bond, the smaller the gap between the composite tape and the cable, reducing the amount of gas between them. Consequently, the probability of air bubbles forming on the cable surface when the composite tape is subjected to the heat pressure of the heated silicone is lower, further improving cable production quality. Furthermore, the micropores extend from the periphery of the heated silicone to the point where it contacts the composite tape. Therefore, during shrinkage, any residual gas between the heated silicone and the composite tape is extracted through the micropores, minimizing the possibility of residual gas being squeezed into the space between the composite tape and the cable surface, further improving product quality.

[0025] 4. In this embodiment, the diameter of the heating silicone decreases from the middle part to the two side components. Therefore, when the inner diameter of the heating silicone shrinks, the middle part of the inner hole of the heating silicone first abuts and squeezes the composite tape, and then the heating silicone sequentially abuts and squeezes the composite tape from the middle part to both sides. Therefore, during the shrinkage and squeezing process of the heating silicone, the heating silicone can squeeze out some of the air between the composite tape and the cable, so as to minimize the occurrence of air between the cable and the composite tape inside the heating silicone, thereby further improving the production quality of the cable. At the same time, the heating silicone in this application, which sequentially squeezes from the middle part to both sides, can also smooth out the composite tape on this part of the cable, so as to avoid wrinkles in the composite tape, thereby further improving the production quality of the cable.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail below.

[0033] A cable aluminum-plastic composite tape longitudinal wrapping device, as described in the reference Figure 1 , Figure 2 and Figure 3 It includes a frame 1, a covering mechanism 2, a wire feeding mechanism 3, a tape feeding mechanism 4, a heating mechanism 5, and a shrink assembly 6.

[0034] The covering mechanism 2 in this embodiment includes a mold 21 and a stabilizing mold 22.

[0035] In this embodiment, the mold 21 is fixedly mounted on the frame 1 in the horizontal direction. The mold 21 is generally trumpet-shaped, and the diameter of the mold 21 gradually decreases from one end to the other. In this embodiment, the stabilizing mold 22 is generally set as a cuboid. The stabilizing mold 22 has a through hole in the horizontal direction for the cable to pass through. The narrow end of the mold 21 is fixedly connected to the stabilizing mold 22, and the narrow end of the mold 21 is coaxially connected to the through hole on the stabilizing mold 22. The inner wall of the through hole is ceramic. The friction between the ceramic and the composite tape on the cable is relatively small, so the cable can pass smoothly through the through hole on the stabilizing mold 22. The diameter of the through hole is slightly larger than the diameter of the cable.

[0036] In this embodiment, the cable feeding mechanism 3 is configured as a roller wound with cable. The roller wound with cable is rotatably mounted on the frame 1. Then, the cable passes sequentially through the through holes on the mold 21 and the stabilizing mold 22 from the needle end of the mold 21. It should be noted that in actual production, after the composite tape is wrapped around the cable surface by the wrapping mechanism, the composite tape usually does not immediately and completely adhere to the cable surface, and there may be some areas that are not fully adhered or have small gaps. In actual production, at the end of the entire production line, there is a roller (not shown in the figure) that winds and collects the cable that has been completely wrapped with aluminum-plastic composite tape. During the rotation and collection process, the roller pulls the cable to move axially continuously, and the rotation of the roller is usually driven by a motor or other equipment with strong torque and load.

[0037] To maintain the stability of the wire feeding mechanism 3 during wire feeding, a support frame 23 is provided on the frame. A limit wheel 31 is also rotatably installed on the support frame 23. A groove is provided on the peripheral wall of the limit wheel 31, and the cable is just stuck in the groove on the limit wheel 31. The setting of the limit wheel 31 can minimize the lateral movement of the cable during the wire feeding process. Therefore, the limit wheel 31 can ensure that the cable is located in the middle part of the lower composite belt as much as possible. Thus, when the composite belt is bent by the mold 21, the composite belt can wrap relatively evenly on the surface of the cable.

[0038] The frame 1 is also equipped with a bending guide wheel 24, which is rotatably mounted on the frame 1 in a horizontal direction. The bending guide wheel 24 is located directly below the limiting wheel 31. The composite belt is closely attached to the peripheral wall below the bending guide wheel 24. The bending guide wheel 24 can exert a certain traction on the composite belt. In this embodiment, the diameter of the bending guide wheel 24 gradually decreases from the middle part to the two sides. Therefore, when the composite belt passes through the surface of the bending guide wheel 24, the composite belt is affected by its shape, and the two sides of the composite belt tend to bend and fold upwards, so that the subsequent mold 21 can bend the composite belt into a tubular shape.

[0039] In this embodiment, the tape feeding mechanism 4 is configured as a roller wound with composite tape. The roller is rotatably mounted on the frame 1 and located below the wire feeding mechanism 3. One end of the composite tape passes through the through holes on the mold 21 and the stabilizing mold 22 in sequence from the wide port of the mold 21. During the process of the composite tape passing through the mold 21, due to the special shape of the mold 21, the mold 21 can bend the composite tape into a tubular shape. Then, when the tubular composite tape passes through the through hole of the stabilizing mold 22, the through hole on the stabilizing mold 22 can further deform the tubular composite tape, so that the diameter of the tubular composite tape is closer to the design value. Since the diameter of the cable is slightly smaller than the inner diameter of the through hole, the composite tape will not completely adhere to the surface of the cable after passing through the through hole.

[0040] Reference Figure 4 and Figure 5 In this embodiment, the heating mechanism 5 includes a fixed base 51 and a heating silicone 52.

[0041] The fixing seat 51 is fixedly installed on the frame 1, and the fixing seat 51 is located on the side of the stabilizing mold 22 that is relatively far away from the mold 21. The fixing seat 51 has an installation groove 511 for installing the heating silicone 52. The installation groove 511 is coaxially arranged with the through hole on the stabilizing mold 22. In this embodiment, the heating silicone 52 is set as an annular shape. The heating silicone 52 is coaxially installed in the installation groove 511. After the cable wrapped with composite tape passes through the through hole of the stabilizing mold 22, the cable wrapped with composite tape will continue to coaxially pass through the inner hole of the heating silicone 52. In the initial state, the inner peripheral wall of the heating silicone 52 does not contact the composite tape on the cable. A heating wire 512 is provided on the groove wall of the installation groove 511. The heating wire 512 abuts against the two ends of the heating silicone 52. The heating wire 512 is electrically connected to an external power source (not shown in the figure).

[0042] In this embodiment, the shrinkage component 6 is configured as an air suction pump.

[0043] The suction pump is fixedly mounted on the mounting base 51. In this embodiment, a sealed space is left between the outer peripheral wall of the heating silicone 52 and the groove wall of the mounting groove 511, and the output end of the suction pump is connected to this sealed space. The composite tape in this embodiment is an aluminum-plastic composite tape, which mainly includes an aluminum layer and a plastic layer. The plastic layer is adhered to the aluminum layer. The main function of the plastic layer is to provide adhesion and insulation protection. The plastic layer can be melted by heating or activated by hot melt adhesive to form a firm bond with the cable sheath, ensuring a tight bond between the shielding layer (aluminum layer) and the cable. If the cable already has an insulation layer, the plastic layer can prevent the aluminum layer from directly contacting the cable conductor, preventing electrochemical corrosion. The aluminum layer mainly plays the role of electromagnetic shielding and mechanical protection. The aluminum layer facing outward can effectively reflect electromagnetic waves and provide anti-interference (EMI / RFI shielding) function. At the same time, the aluminum layer has high hardness, and facing outward can enhance the cable's resistance to pressure and scratches. In the actual wrapping process, the plastic layer of the aluminum-plastic composite tape is attached to the surface of the cable, while the aluminum layer is in contact with the heating silicone 52.

[0044] When the equipment is started, the composite tape in the tape feeding mechanism 4 enters the interior of the mold 21 from the needle end of the mold 21. At the same time, the cable in the wire feeding mechanism 3 also enters the interior of the mold 21 from the needle end of the mold 21. Since the diameter of the mold 21 gradually decreases from the wide end to the narrow end, the mold 21 bends the composite tape into a cylindrical shape during the movement of the cable and the composite tape, so that the bent composite tape is sleeved on the cable. Then, as the cable and the composite tape continue to move, the cable wrapped with the composite tape enters the through hole of the stabilizing mold 22. The hole wall of the stabilizing mold 22 applies a squeezing force to the composite tape in the direction close to the cable, thereby further reducing the diameter of the tubular composite tape, and thus making the diameter of the tubular composite tape closer to the design value.

[0045] Then, the cable emerging from the through hole of the stabilizing mold 22 moves into the inner ring of the heating silicone 52. At this time, the inner wall of the heating silicone 52 does not contact the composite tape on the outer periphery of the cable. When a small portion of the tubular composite tape emerges from the right side of the heating silicone 52, the suction pump is immediately activated. The suction pump extracts the gas from the sealed space between the outer periphery of the heating silicone 52 and the wall of the mounting groove 511, thus placing the heating silicone 52 in a negative pressure space. When the heating silicone 52 is in a negative pressure space, it will elastically contract. After the heating silicone 52 contracts, the diameter of its inner ring will decrease, and the inner wall of the heating silicone 52 will move along the direction close to the composite tape on the outer periphery of the cable until the heating silicone 52 presses the composite tape tightly against the outer periphery of the cable, thus allowing the composite tape to adhere tightly to the surface of the cable. At the same time, the heating silicone 52... The heat emitted softens the plastic layer of the aluminum-plastic composite tape, and the softened plastic layer has a certain degree of stickiness. Therefore, the composite tape adheres to the surface of the cable under the pressure of the heated silicone 52, thereby improving the overall connection strength between the cable and the composite tape. As the cable continues to move, and because the heated silicone 52 is in a contracted state (not continuously contracting, but in a contracted state), the composite tape is pressed tightly against the surface of the cable. As a result, the residual air between the cable and the composite tape is squeezed out by the heated silicone 52 in the opposite direction of the cable's movement. The reduction of gas between the cable and the composite tape greatly reduces the probability of air bubbles appearing on the surface of the cable wrapped with the composite tape, thus minimizing the possibility of air bubble breakage leading to cable exposure and improving the cable's production quality.

[0046] In general, when the heated silicone 52 contracts under negative pressure and tightens onto the cable surface, it exerts radial pressure on the composite tape, ensuring a firm adhesion. Simultaneously, the silicone releases heat, softening or melting the plastic layer within the composite tape. This softened plastic layer better adheres to the cable surface, reducing the gap between the cable and the composite tape and further strengthening their connection. Furthermore, as the heated silicone tightens onto the cable surface, the presence of a roller at the end of the device for winding and collecting the cable fully covered with the aluminum-plastic composite tape causes the cable to move horizontally to the right. This process is further facilitated by the heated silicone 52 tightening onto the cable surface. When the heated silicone 52 and the cable slide relative to each other, the cable with the composite tape will be squeezed by the heated silicone 52 when it touches the heated silicone 52. The diameter of the cable with the composite tape is larger than the diameter of the cable on the inner wall of the heated silicone 52. Therefore, when the cable with the composite tape just touches the heated silicone 52, the left side wall of the heated silicone 52 will contact the composite tape on the cable first and generate a radial squeezing force and an axial squeezing force to the left on the composite tape. The radial squeezing force makes the composite tape fit the cable better, while the axial squeezing force to the left can squeeze out the residual air between the composite tape and the cable surface. Since the composite tape on the cable surface passing through the through hole of the stabilizing mold 22 is not completely attached, the heated silicone 52 can continuously discharge the residual gas between the cable and the composite tape to the left.

[0047] It should be noted that before starting the suction pump to shrink the heated silicone 52, the composite tape on the cable can be partially passed through the heated silicone 52 before starting the shrinking assembly 6 to shrink the heated silicone 52. This ensures that the heated silicone 52 tightly presses the composite tape onto the surface of the cable, thus minimizing the risk of the ends of the composite tape wrapped around the cable surface being squeezed by the heated silicone 52 and peeling off the cable surface. This situation often occurs when replacing new composite tape. Therefore, with the design of this suction pump and heated silicone 52, this equipment can avoid the occurrence of the above situation, greatly improving the practicality of the equipment.

[0048] In addition, it should be noted that silicone rubber is a rubber material with excellent thermal conductivity and heat resistance. It has a high thermal conductivity, which can effectively transfer heat and reduce thermal resistance. At the same time, silicone rubber also has excellent heat resistance and can maintain good elasticity over a wide temperature range. Silicone rubber can work stably at a temperature of 250 degrees Celsius, while the heating temperature of the composite belt in this embodiment only needs to be 200 degrees Celsius. Therefore, the heating silicone rubber 52 in this embodiment can adapt well to high-temperature operation. In addition, the material properties of rubber also allow it to elastically shrink under negative pressure. Combined with the setting of this suction pump, it can be perfectly matched with the operation of this equipment and has relatively high practicality.

[0049] Because rubber is elastic, on the one hand, when the heated silicone 52 presses the composite tape onto the surface of the cable, it does not engage in rigid friction with the composite tape, thus minimizing damage and providing some protection. On the other hand, when the cable surface is not perfectly smooth, the rubber's elastic deformation allows it to adhere relatively tightly to the cable's outer wall, enabling the composite tape to fit snugly against the cable's outer wall. This further reduces the gap between the composite tape and the cable's outer wall, thereby increasing the connection strength. Simultaneously, the reduced gap between the composite tape and the cable's outer wall also reduces the amount of gas between them, further decreasing the probability of air bubbles appearing on the surface of the cable wrapped with the composite tape, thus improving the cable's production quality.

[0050] In this embodiment, a plurality of micropores 521 are provided on the outer peripheral wall of the heating silicone 52. The plurality of micropores 521 are arrayed on the peripheral wall of the heating silicone 52, and the plurality of micropores 521 are evenly spaced around the axis of the heating silicone 52. Each micropore 521 extends to the contact point between the heating silicone 52 and the composite tape.

[0051] When the gas in the space between the heated silicone rubber 52 and the wall of the mounting groove 511 is completely evacuated by the suction pump, the gas in the micropores 521 on the heated silicone rubber 52 will also be evacuated. Therefore, the shrinkage time of the heated silicone rubber 52 will be shorter and the shrinkage amplitude greater, allowing the heated silicone rubber 52 to apply relatively greater compressive force to the composite tape. This results in a tighter bond between the composite tape and the cable surface, further improving the connection strength between the composite tape and the cable. Simultaneously, the tighter the bond between the composite tape and the cable, the smaller the gap between them. Therefore, the gas between the cable and the composite tape... The fewer the heat, the lower the probability of air bubbles forming on the cable surface when the composite tape on the cable is subjected to the heat pressure of the heated silicone 52, thus further improving the production quality of the cable. On the other hand, the micropore 521 in this application extends from the peripheral wall of the heated silicone 52 directly to the contact point between the heated silicone 52 and the composite tape. Therefore, when the heated silicone 52 shrinks, the gas remaining between the heated silicone 52 and the composite tape will also be extracted through the micropore 521, thereby minimizing the possibility of the remaining gas being squeezed into the space between the composite tape and the cable surface, thus further improving the production quality of the product.

[0052] In this embodiment, since the heating silicone 52 initially contacts the composite tape on the cable, and the inner hole of the heating silicone 52 has a certain length in the horizontal direction, the portion of the composite tape on the cable surface that initially contacts this length of the heating silicone 52 will only be subjected to radial extrusion force. Therefore, residual air between this portion of the cable surface and the composite tape is difficult to expel. Thus, in this embodiment, the diameter of the inner hole of the heating silicone 52 gradually decreases from the middle to both sides. Therefore, when the inner hole diameter of the heating silicone 52 initially shrinks, the middle portion of the inner hole of the heating silicone 52 first abuts against and compresses the composite tape, and then the heating silicone 52 sequentially abuts against and compresses the composite tape from the middle to both sides. Therefore, during the initial shrinkage and extrusion process of the heating silicone 52, the heating silicone 52 can apply axial extrusion to the composite tape on the cable. The heating silicone 52 is used to expel some of the gas between the composite tape and the cable towards both sides (the left side continues to be discharged as described above, while the right side is discharged through the rightmost end of the composite tape; as explained above, the heating silicone 52 will only contract when a small portion of the tubular composite tape passes through the right side). This is to minimize the possibility of air remaining between the cable and the composite tape within the heating silicone 52. Subsequently, as the cable moves axially, the residual gas between the cable and the composite tape is discharged as described above, thereby further improving the cable's production quality. Furthermore, the heating silicone 52 in this application, by extruding the gas from the middle to both sides, can also smooth the composite tape on that portion of the cable, preventing wrinkles and further improving the cable's production quality.

[0053] Secondly, refer to Figure 2 and Figure 3 In this embodiment, the frame 1 is also provided with a positioning mechanism 7.

[0054] The positioning mechanism 7 in this embodiment includes two sets of positioning wheels 72 and two mounting brackets 71. The two mounting brackets 71 and the two sets of positioning wheels 72 correspond one-to-one. The two are mounted on the fixed mounting frame 1 and are arranged opposite each other on both sides of the fixed base 51. One of the mounting brackets 71 is located between the fixed base 51 and the stabilizing mold 22. Each set has two positioning wheels 72. Both positioning wheels 72 are rotatably mounted on the mounting bracket 71. The two positioning wheels 72 are arranged opposite each other in the vertical direction, and the distance between the outer peripheral walls of the two positioning wheels 72 is the same as the diameter of the cable. The two positioning wheels 72 on the other mounting bracket 71 have the same structure as the positioning wheels 72 described above.

[0055] The two sets of positioning wheels 72 provide a certain degree of fixation for the cable. Therefore, the probability of the cable swaying during movement is relatively low when it is located between the two sets of positioning wheels 72. The heating silicone 52 on the fixing base 51 is also located between the two sets of positioning wheels 72. Therefore, when the heating silicone 52 contracts and squeezes the composite tape onto the cable surface, the cable will not sway. Thus, the pressure applied to the cable surface by the heating silicone 52 is relatively uniform, which allows the composite tape to adhere tightly to the cable surface at every point, thereby improving the connection strength between the composite tape and the cable. At the same time, it also minimizes the possibility of uneven cable surface caused by uneven pressure.

[0056] A driving component 73 is also provided on the mounting bracket 71 located on the side of the fixed base 51 that is relatively far away from the stabilizing mold 22. In this embodiment, the driving component 73 includes two gears 732 and a driving motor 731. The two gears 732 are rotatably mounted on the mounting bracket 71. The two gears 732 correspond one-to-one with the two positioning wheels 72 on the mounting bracket 71. The gears 732 and the positioning wheels 72 are coaxially fixedly connected and mesh with each other. The driving motor 731 is mounted on the mounting bracket 71, and the output shaft of the driving motor 731 is coaxially fixedly connected with one of the gears 732.

[0057] When the drive motor 731 starts, the two gears 732 rotate in opposite directions, thereby driving the two positioning wheels 72 on the mounting bracket 71 to rotate in opposite directions. Thus, the two positioning wheels 72 on the mounting bracket 71 can also play a partial traction role on the cable.

[0058] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
