A fastening device for wire and cable harnesses

Abstract

The present invention is applicable to the technical field of wire and cable harness fastening, and provides a wire and cable harness fastening device, which includes a main body component. The main body component includes a fixing plate, an upper plate and a lower plate connected to the same side of the fixing plate. The upper plate is located above the lower plate. A support component is installed on the side of the fixing plate away from the upper plate. Two groups of auxiliary components for guiding are symmetrically installed on the top of the upper plate. This device solves the problems of uneven sag and uneven tightness when multiple cable harnesses are clamped and adjusted at the same time, as well as the cumbersome problem that when a single cable is disassembled, the clamping of all cables needs to be cancelled and re-fastened. By setting a rotating shaft, a driving shaft and multiple groups of adjustment mechanisms, the cables can pass through different combinations of the rotating shaft and the driving shaft respectively to achieve independent fastening, retracting and releasing, and the cables do not affect each other. Moreover, through the drive of the winding motor and the rotation of the winding rod, the cables can be independently retracted and released at both ends of the fixed point.

Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable harness fastening, and more specifically, it relates to a wire and cable harness fastening device. Background Art

[0002] Wires and cables are wire products used for transmitting electricity, signals, and data. They are composed of one or more insulated wires. During the use process of power cables in power transmission, distribution, electrified railways, etc., they will sag under their own gravity and external forces, that is, catenary. If the sag degree is relatively large, a wire and cable harness fastening device is required to adjust the sag degree of the cable.

[0003] Currently, the existing device fixes the device to a telegraph pole by setting a support base, and the wire passes through the rubber ring and is reserved and pressed between the wire-attaching body. The movable ring can slide to divide the wire. When approaching the fixed ring, the internal components are inflated, so that the cable is pushed into the groove of the ring and separated and guided. Rotating the movable ring drives the ring wire rod to wind the cable, and the fastening ring is fixed to the insertion rod. When paying out the wire, the fastening ring is removed and the movable ring is flipped. The whole process realizes the convenient fastening and wire management of wires and cables.

[0004] However, this method clamps multiple cable harnesses at the same time and adjusts the sag degree at the same time. When adjusting simultaneously, the sag degrees of multiple cables may be different and the tightness may be inconsistent. Moreover, when removing one of the cables, all cables need to be unclamped, which will cause the cables to be released and sag. And after the cable is disassembled, the other cables need to be re-fastened. This method greatly increases the fastening complexity of the fastening device. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a wire and cable harness fastening device.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A wire and cable harness fastening device, including a main body assembly. The main body assembly includes a fixing plate and an upper plate and a lower plate connected to the same side of the fixing plate. The upper plate is located above the lower plate. A support assembly is installed on the side of the fixing plate away from the upper plate. Two groups of auxiliary assemblies for guiding are symmetrically installed on the top of the upper plate. A winding assembly for winding the wire is installed on the top of the upper plate and between the two groups of auxiliary assemblies. An adjusting assembly is installed at the bottom of the lower plate, and the top end of the adjusting assembly penetrates through the lower plate and the upper plate.

[0007] The main body assembly further includes two rotating shafts symmetrically and rotatably connected to the top of the upper plate. A first wire wheel set is connected to the outer side wall of each rotating shaft. Two driving motors are symmetrically installed at the bottom of the lower plate. The output ends of the two driving motors penetrate through the bottom of the lower plate and are connected to driving shafts. The top of the driving shafts extends to the top of the upper plate and is connected to second wire wheel sets. The two second wire wheel sets are both located between the two rotating shafts, and one of the second wire wheel sets and the rotating shaft form a group.

[0008] The adjusting assembly includes two connecting rods arranged on the top of the upper plate. A third wire wheel is connected to the outer side wall of each connecting rod. The two third wire wheels are arranged corresponding to two groups of auxiliary assemblies.

[0009] The winding assembly includes a fixing frame installed on the top of the upper plate and bearing plates equidistantly installed inside the fixing frame. An adjusting mechanism is installed on the top of each bearing plate.

[0010] Each group of adjusting mechanisms includes a positioning block installed on the top of the corresponding bearing plate. A positioning column is arranged on the top of the positioning block. A groove is formed on the outer side wall of the positioning column. A clamp is sleeved on the outer side wall of the positioning column. The clamp is connected to the positioning block by bolts. A protrusion is connected to the inner wall of the clamp. The protrusion is arranged corresponding to the groove. Both ends of the positioning column are rotatably connected to winding rods. Two winding motors are symmetrically installed on the top of the positioning block. The output end of each winding motor is connected to a second gear. First gears are connected to the outer side walls of the two winding rods. The two first gears are arranged corresponding to the two second gears. The first gear meshes with the corresponding second gear.

[0011] The present invention is further configured as: spiral wire grooves and spiral chutes are formed on the outer side walls of each winding rod, and the spiral wire grooves and the spiral chutes are arranged staggeredly.

[0012] The present invention is further configured as: plates are connected to the outer side walls of the two winding rods. Guide rods are connected to the opposite sides of the two plates. A tube is slidably connected to the outer side wall of the guide rod. A convex rod is connected to the outer side wall of the tube. The end of the convex rod is inserted into the inside of the spiral chute. A fourth wire wheel is sleeved and connected to the outer side wall of the tube. The fourth wire wheel is arranged corresponding to the spiral wire groove.

[0013] By adopting the above technical solution, the cable passes through between the corresponding wheel bodies on the rotating shaft and the driving shaft. These two sets of wheel bodies cooperate to convey the cable. Since two sets of rotating shafts and driving shafts are provided, the same cable can pass through between one rotating shaft and driving shaft and then pass out between the other rotating shaft and driving shaft. By adjusting the connection and separation of the rotating shaft and the corresponding wheel body and the connection and separation of the driving shaft and the corresponding wheel body, the purpose of separately winding and unwinding different cables can be achieved, and the purpose of fixing a single cable can be achieved. Multiple cables are separately fixed by multiple sets of adjustment mechanisms, and multiple cables do not affect each other. When the adjustment mechanism winds a single cable, the cable is first fixed, and then the winding motor drives the second gear to rotate. The first gear drives the corresponding winding rod to rotate synchronously. During the rotation process of the winding rod, the plate body and the guide rod are driven to rotate and displace, causing the guide rod to squeeze and wind the cable, so that the cable is wound on the outer side wall of the corresponding winding rod, that is, the winding and unwinding operations are respectively carried out at both ends of the fixed point of the cable, and the two ends of the same cable do not affect each other.

[0014] Before the cable is pressed inside the groove, it first passes between the fourth wire wheel and the winding rod. During the rotational displacement of the guide rod, the tube body is driven to move synchronously. The convex rod on the outer wall of the tube body is limited by the spiral chute. When the tube body rotates and displaces following the guide rod, the convex rod slides on the outer side wall of the guide rod. At the same time, the tube body surrounds and squeezes the cable, causing the cable to be gradually wound along the extension direction of the spiral wire groove. And the two winding rods can respectively carry out fastening operations on both ends of the cable, and the cable will not be disordered, improving the maintainability during the winding and unwinding of the cable.

[0015] The present invention is further configured as: both sets of the auxiliary components include brackets installed on the top of the upper plate. An electric turntable is installed at the bottom of the bracket. The output end of the electric turntable is coaxially arranged with the connecting rod. A telescopic plate is horizontally connected to the bottom of the output end of the electric turntable. An auxiliary rod is vertically connected to the bottom of the telescopic plate. A plurality of collar rings are equidistantly connected to the outer side wall of the auxiliary rod.

[0016] By adopting the above technical solution, in order to avoid the situation of entanglement of multiple cables before entering the adjustment mechanism, when the cable passes through the third wire wheel, the electric turntable drives the telescopic plate, the auxiliary rod and the plurality of collar rings to displace synchronously, so that the multiple cables passing through the third wire wheel are separated to avoid mutual entanglement. And by using the function that the telescopic plate can be telescopic, when the third wire wheel displaces, the telescopic plate drives the auxiliary rod and the collar rings to move, and in cooperation with the rotation of the electric turntable, it is ensured that the plurality of collar rings can be kept in a fitting state with the third wire wheel, so that when multiple cables are separately fixed, they do not affect each other.

[0017] The present invention is further configured such that: two second arc-shaped grooves are symmetrically formed at the top of the upper plate, and the two connecting rods are respectively inserted into the two second arc-shaped grooves. A rotating rod is slidably connected to the top of the lower plate, and two swing plates are hinged to the outer side wall of the rotating rod, and the two swing plates are respectively hinged to the two connecting rods.

[0018] The present invention is further configured such that: a mounting plate is installed at the bottom of the lower plate, and guiding grooves are formed at the bottom of the mounting plate and the bottom of the lower plate. The bottom of the rotating rod penetrates through the guiding groove, and an electric push rod is installed at the bottom of the mounting plate, and the output end of the electric push rod is connected to the outer side wall of the rotating rod.

[0019] The present invention is further configured such that: two first arc-shaped grooves are symmetrically formed at the bottom of the lower plate, the two first arc-shaped grooves are arranged corresponding to the two second arc-shaped grooves, and a roller is rotatably connected to the inside of each first arc-shaped groove. The two connecting rods are arranged corresponding to the two rollers, and the bottom of the connecting rod is rotatably connected to the top of the roller.

[0020] By adopting the above technical solution, the electric push rod drives the rotating rod to move inside the guiding groove, and the rotating rod pulls one end of the two swing plates to displace. Since the connecting rod connected to the other end of the swing plate is limited by the second arc-shaped groove, the swing plate pulls the connecting rod to slide inside the second arc-shaped groove, and the connecting rod drives the corresponding third wire wheel to displace, thereby adjusting the distance between the two third wire wheels. When the connecting rod displaces, it drives the corresponding roller to swing inside the corresponding first arc-shaped groove, thereby guiding the displacement of the connecting rod. When multiple cables are recycled, they are wound around the outer wall of the third wire wheel after passing between the driving shaft and the rotating shaft. After the distance between the two third wire wheels is adjusted to a proper distance and remains stationary, the tightness of the recycled cables changes synchronously, and multiple cables are in a separated and taut state, preventing the cables from piling up, overlapping, squeezing and winding each other in the same area when they are recycled into the main body assembly.

[0021] The present invention is further configured such that: the support assembly includes a support frame arranged on the side of the fixing plate away from the upper plate, and the support frame is arranged in a U shape upwards.

[0022] The present invention is further configured such that: two fixing bars are symmetrically installed on the side of the fixing plate away from the upper plate, and insertion rods are connected to the opposite sides of the two fixing bars. A sleeve is connected to the outer side wall of each insertion rod, and the two sleeves are both connected to the support frame.

[0023] The present invention is further configured such that: two shells are symmetrically installed at the end of the support frame away from the fixing plate, and a spring plate is inserted and connected inside each shell, and a rotating roller is connected between the two spring plates.

[0024] By adopting the above technical solution, the cable is supported by the cooperation of the support frame and the roller, which alleviates the sagging of the cable. Moreover, when the cable enters the main body assembly, the angle of the cable can be adjusted first, alleviating the situation of pulling and wearing when the cable directly enters the main body assembly under the sagging condition. When the cable sways under the influence of the external environment, the swaying force is applied to the roller and the spring plate, and the elastic force of the spring plate buffers and compensates the swaying force of the cable, preventing the cable from being broken due to excessive swaying force.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] (1) By setting the rotating shaft and the driving shaft, the cable passes through between the corresponding wheel bodies on the rotating shaft and the driving shaft. These two groups of wheel bodies cooperate to convey the cable. Since two groups of the rotating shaft and the driving shaft are provided, the same cable can pass through between one rotating shaft and driving shaft and then pass out between another rotating shaft and driving shaft. By adjusting the connection and separation of the rotating shaft and the corresponding wheel body and the connection and separation of the driving shaft and the corresponding wheel body, the winding and unwinding of different cables can be achieved respectively, and the purpose of fixing a single cable can be achieved.

[0027] (2) By setting multiple groups of adjustment mechanisms, multiple cables are respectively fastened by multiple groups of adjustment mechanisms, and the multiple cables do not affect each other. When the adjustment mechanism winds a single cable, the cable is first fixed, and then the winding motor drives the second gear to rotate. The first gear drives the corresponding winding rod to rotate synchronously. During the rotation process of the winding rod, the plate body and the guide rod are driven to rotate and displace, causing the guide rod to squeeze and wind the cable, so that the cable is wound around the outer side wall of the corresponding winding rod, that is, the two ends of the cable at the fixed point are respectively wound and unwound, and the two ends of the same cable do not affect each other.

[0028] (3) Before the cable is pressed into the groove, it first passes between the fourth wire wheel and the winding rod. During the rotational displacement of the guide rod, the tube body is driven to move synchronously. The convex rod on the outer wall of the tube body is limited by the spiral chute. When the tube body rotates and displaces following the guide rod, the convex rod slides on the outer side wall of the guide rod. At the same time, the tube body surrounds and squeezes the cable, causing the cable to be gradually wound along the extension direction of the spiral wire groove. And the two winding rods can respectively fasten the two ends of the cable, and the cable will not be disordered, improving the maintainability during the winding and unwinding of the cable.

[0029] (4) The cable is supported by the cooperation of the support frame and the roller, which alleviates the sagging of the cable. Moreover, when the cable enters the main body assembly, the angle of the cable can be adjusted first, alleviating the situation of pulling and wearing when the cable directly enters the main body assembly under the sagging condition. When the cable sways under the influence of the external environment, the swaying force is applied to the roller and the spring plate, and the elastic force of the spring plate buffers and compensates the swaying force of the cable, preventing the cable from being broken due to excessive swaying force.

Detailed implementation manners

[0045] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0046] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0047] Please refer to Figures 1-10 , the present invention provides the following technical solutions:

[0048] In the first embodiment, the existing method is to clamp multiple cable harnesses simultaneously and adjust the sag degree simultaneously. When adjusting simultaneously, the sag degrees of multiple cables may be different and the tightness may be inconsistent. Moreover, when removing one cable, all cables need to be unclamped, which will cause the cables to be released and sag. After the cable is removed, the other cables need to be re-fastened. This method greatly increases the fastening complexity of the fastening device.

[0049] For this reason, refer to Figure 1 and Figure 2, A wire and cable harness fastening device, including a main body assembly 1. The main body assembly 1 includes a fixing plate 11, an upper plate 12 and a lower plate 13 connected to the same side of the fixing plate 11. The upper plate 12 is located above the lower plate 13. The fixing plate 11, the upper plate 12 and the lower plate 13 cooperate to form a main body structure. The main body assembly 1 further includes two rotating shafts 14 symmetrically and rotatably connected to the top of the upper plate 12. A first wire wheel group 15 is connected to the outer side wall of each rotating shaft 14. Two driving motors 18 are symmetrically installed at the bottom of the lower plate 13. The output ends of the two driving motors 18 penetrate through the bottom of the lower plate 13 and are connected to a driving shaft 17. The top of the driving shaft 17 extends to the top of the upper plate 12 and is connected to a second wire wheel group 16. Both second wire wheel groups 16 are located between the two rotating shafts 14, and one of the second wire wheel groups 16 and the rotating shaft 14 form a group. The first wire wheel group 15 and the second wire wheel group 16 are both composed of a plurality of wheel bodies. The wheel bodies in the first wire wheel group 15 are rotatably connected to the corresponding rotating shafts 14 through bearings, and the wheel bodies in the first wire wheel group 15 are locked to the rotating shafts 14 by bolts. The wheel bodies in the second wire wheel group 16 are rotatably connected to the corresponding driving shafts 17 through bearings, and the wheel bodies in the second wire wheel group 16 are locked to the driving shafts 17 by bolts. When the wheel bodies in the second wire wheel group 16 are connected to the driving shafts 17, the driving motors 18 can drive the corresponding wheel bodies to rotate, thereby driving the rotation of the wheel bodies corresponding to the rotating shafts 14. The wheel bodies corresponding to the rotating shafts 14 are locked to the rotating shafts 14, and the rotating shafts 14 rotate synchronously. The wheel bodies on the driving shafts 17 and the rotating shafts 14 that are not locked are not subjected to rotational force.

[0050] The cable can pass through between the corresponding wheel bodies on the rotating shafts 14 and the driving shafts 17. These two groups of wheel bodies cooperate to convey the cable. Since there are two groups of both the rotating shafts 14 and the driving shafts 17, the same cable can pass through between one rotating shaft 14 and the driving shaft 17, and then pass out between another rotating shaft 14 and the driving shaft 17. By adjusting the connection and separation of the rotating shafts 14 and the corresponding wheel bodies and the connection and separation of the driving shafts 17 and the corresponding wheel bodies, the purpose of separately winding and unwinding different cables and separately fastening a single cable can be achieved. If multiple cables need to be wound and unwound simultaneously, only the connection of the rotating shafts 14 and the driving shafts 17 to the corresponding wheel bodies needs to be adjusted again.

[0051] Refer to Figures 1-3 , On the side of the fixing plate 11 away from the upper plate 12, a support assembly 2 is installed. The support assembly 2 is used to play an auxiliary support role during the cable conveyance, to avoid the situation where the cable sags when entering the main body assembly 1, resulting in friction between the cable and the main body assembly 1 and causing damage. The specific structure of the support assembly 2 is as follows:

[0052] Refer to Figure 3, the support component 2 includes a support frame 24 disposed on the side of the fixed plate 11 away from the upper plate 12. The support frame 24 is arranged in a U shape upward. Two fixing bars 21 are symmetrically installed on the side of the fixed plate 11 away from the upper plate 12. On the opposite sides of the two fixing bars 21, insertion rods 23 are connected. A sleeve 22 is connected to the outer side wall of each insertion rod 23. The two sleeves 22 are both connected to the support frame 24. The support frame 24 is positioned by inserting the insertion rods 23 into the corresponding sleeves 22. The sleeves 22 and the insertion rods 23 are both square tubes, which prevent rotation after connection. And screws that can be locked are provided outside the sleeves 22 to ensure that the insertion rods 23 can be stably inserted into the sleeves 22.

[0053] Refer to Figure 3 , at the end of the support frame 24 away from the fixed plate 11, two shells 25 are symmetrically installed. A spring plate 26 is inserted and connected inside each shell 25. A roller 27 is connected between the two spring plates 26. The roller 27 is used to contact the cable. The cable is supported by the cooperation of the support frame 24 and the roller 27, which alleviates the cable sag. Moreover, when the cable enters the main body component 1, the angle of the cable can be adjusted first, which alleviates the situation of pulling and wearing when the cable directly enters the main body component 1 when sagging.

[0054] The roller 27 is set in a shape that is thinner in the middle and thicker at both ends. When the cable contacts the roller 27, it is in the thinner position to prevent the cable from slipping. When the cable sways under the influence of the external environment, the swaying force is applied to the roller 27 and the spring plate 26, and the elastic force of the spring plate 26 buffers and compensates the swaying force of the cable to prevent the cable from being broken due to excessive swaying force.

[0055] In the second embodiment, when the cable is recovered into the main body component 1, since the number of cables is large and the cables are all stacked in the same area, if the bending arc of the cable after recovery is too large, the cables will overlap, squeeze and entangle with each other, and the cable in this state cannot be released.

[0056] For this reason, refer to Figure 2 、 Figures 4-6 , two groups of auxiliary components 3 for guiding are symmetrically installed on the top of the upper plate 12. An adjusting component 4 is installed at the bottom of the lower plate 13. The top end of the adjusting component 4 penetrates through the lower plate 13 and the upper plate 12. The adjusting component 4 is used to adjust the tightness of the cable recovery position, and the auxiliary component 3 is used to guide and organize the cable. The specific structure of the adjusting component 4 is as follows:

[0057] Refer to Figure 2 、 Figures 4-6, the adjusting assembly 4 includes two connecting rods 48 arranged on the top of the upper plate 12. Two second arc-shaped grooves 49 are symmetrically formed on the top of the upper plate 12. The two connecting rods 48 are respectively inserted into the two second arc-shaped grooves 49. A rotating rod 43 is slidably connected to the top of the lower plate 13. Two swing plates 47 are hinged to the outer side wall of the rotating rod 43. The two swing plates 47 are respectively hinged to the two connecting rods 48. The second arc-shaped groove 49 is used to guide the connecting rod 48. Moreover, a third wire wheel 401 is connected to the outer side wall of each connecting rod 48. The two third wire wheels 401 are arranged corresponding to the two groups of auxiliary assemblies 3.

[0058] Refer to Figure 2 , Figures 4-6 , an installation plate 41 is installed at the bottom of the lower plate 13. Guide grooves 46 are formed at the bottom of the installation plate 41 and the bottom of the lower plate 13. The bottom of the rotating rod 43 penetrates through the inside of the guide groove 46. An electric push rod 42 is installed at the bottom of the installation plate 41. The output end of the electric push rod 42 is connected to the outer side wall of the rotating rod 43. The electric push rod 42 is used to drive the rotating rod 43 to move inside the guide groove 46. The rotating rod 43 pulls one end of the two swing plates 47 to displace. Since the connecting rod 48 connected to the other end of the swing plate 47 is limited by the second arc-shaped groove 49, the swing plate 47 then pulls the connecting rod 48 to slide inside the second arc-shaped groove 49. The connecting rod 48 drives the corresponding third wire wheel 401 to displace, thereby adjusting the distance between the two third wire wheels 401.

[0059] Refer to Figure 2 , Figures 4-6 , two first arc-shaped grooves 44 are symmetrically formed at the bottom of the lower plate 13. The two first arc-shaped grooves 44 are arranged corresponding to the two second arc-shaped grooves 49. Moreover, a roller 45 is rotatably connected to the inside of each first arc-shaped groove 44. The two connecting rods 48 are arranged corresponding to the two rollers 45. The bottom of the connecting rod 48 is rotatably connected to the top of the roller 45. When the connecting rod 48 displaces, it drives the corresponding roller 45 to swing inside the corresponding first arc-shaped groove 44, thereby guiding the displacement of the connecting rod 48.

[0060] When multiple cables are recycled, they all pass between the driving shaft 17 and the rotating shaft 14 and then are wound around the outer wall of the third wire wheel 401 for guiding. After the distance between the two third wire wheels 401 is adjusted to an appropriate distance, they remain stationary. The tightness of the recycled cables changes synchronously. The multiple cables are in a separated and taut state, preventing the cables from piling up, overlapping, squeezing, and winding in the same area when they are recycled into the main body assembly 1 due to a large number of cables.

[0061] Embodiment 3. When multiple cables are tightened, they are separately adjusted through the wheel bodies on the drive shaft 17 and the rotating shaft 14, without affecting each other. However, if the same cable is wound on the same mechanism, only the two ends can be tightened and released simultaneously. If the tightness of the same cable at both ends of the fastening device is different, simultaneous adjustment will cause one end to be too tight, which may cause the cable to be pulled and broken.

[0062] For this reason, refer to Figure 1 and Figure 7 , a winding component 5 for winding is installed on the top of the upper plate 12 and between two groups of auxiliary components 3. The specific structure of the winding component 5 is as follows:

[0063] The winding component 5 includes a fixing frame 51 installed on the top of the upper plate 12 and bearing plates 52 installed equidistantly inside the fixing frame 51. An adjusting mechanism 53 is installed on the top of each bearing plate 52. The number of bearing plates 52 is the same as the number of cables passing through the fastening device. Multiple groups of adjusting mechanisms 53 wind multiple cables respectively, and the multiple cables do not affect each other.

[0064] Refer to Figures 7-10 , each group of adjusting mechanisms 53 includes a positioning block 531 installed on the top of the corresponding bearing plate 52. A positioning column 532 is arranged on the top of the positioning block 531. A groove is formed on the outer side wall of the positioning column 532. A clamp 534 is sleeved on the outer side wall of the positioning column 532. The clamp 534 is connected to the positioning block 531 by bolts. A protrusion 533 is connected to the inner wall of the clamp 534. The protrusion 533 is arranged corresponding to the groove. Both ends of the positioning column 532 are rotatably connected to winding rods 535. Two winding motors 537 are symmetrically installed on the top of the positioning block 531. The output end of each winding motor 537 is connected to a second gear 538. First gears 536 are connected to the outer side walls of the two winding rods 535. The two first gears 536 are arranged corresponding to the two second gears 538. The first gear 536 meshes with the corresponding second gear 538. The positioning block 531 is used to position the positioning column 532. The groove on the positioning column 532 is used to clamp the cable. That is, the cable directly enters one group of adjusting mechanisms 53 after passing through one of the third wire wheels 401 and is clamped by the groove on the positioning column 532. After the cable is stuck in the groove, the clamp 534 is connected to the positioning block 531, and the protrusion 533 presses the cable tightly in the groove, thereby fixing the cable.

[0065] In this embodiment, refer to Figures 7-10, plate bodies 539 are connected to the outer side walls of both winding rods 535. Guide rods 5303 are connected to the sides of the two plate bodies 539 facing away from each other. The winding motor 537 is used to drive the second gear 538 to rotate. Since the second gear 538 meshes with the first gear 536, when the second gear 538 rotates, the first gear 536 rotates synchronously. The first gear 536 drives the corresponding winding rod 535 to rotate. During the rotation of the winding rod 535, the plate body 539 and the guide rod 5303 are driven to rotate and displace, causing the guide rod 5303 to squeeze and wind the cable, so that the cable is wound on the outer side wall of the corresponding winding rod 535.

[0066] Refer to Figures 7-10 , spiral wire grooves 5301 and spiral chutes 5302 are formed in the outer side walls of each winding rod 535. The spiral wire grooves 5301 and the spiral chutes 5302 are arranged in a staggered manner. A tube body 5304 is slidably connected to the outer side wall of the guide rod 5303. A convex rod 5306 is connected to the outer side wall of the tube body 5304. The end of the convex rod 5306 is inserted into the interior of the spiral chute 5302. A fourth wire wheel 5305 is sleeved and connected to the outer side wall of the tube body 5304. The fourth wire wheel 5305 is arranged corresponding to the spiral wire groove 5301. Before the cable is pressed into the groove, it first passes between the fourth wire wheel 5305 and the winding rod 535. During the rotational displacement of the guide rod 5303, the tube body 5304 is driven to move synchronously. The convex rod 5306 on the outer wall of the tube body 5304 is limited by the spiral chute 5302. When the tube body 5304 rotates and displaces following the guide rod 5303, the convex rod 5306 slides on the outer side wall of the guide rod 5303. At the same time, the tube body 5304 squeezes and surrounds the cable, causing the cable to be gradually wound and collected along the extension direction of the spiral wire groove 5301, and the two winding rods 535 can respectively perform fastening operations on both ends of the cable.

[0067] In this embodiment, each of the two groups of auxiliary components 3 includes a bracket 31 installed on the top of the upper plate 12. An electric rotating table 32 is installed at the bottom of the bracket 31. The output end of the electric rotating table 32 is coaxially arranged with the connecting rod 48. A telescopic plate 33 is horizontally connected to the bottom of the output end of the electric rotating table 32. An auxiliary rod 34 is vertically connected to the bottom of the telescopic plate 33. A plurality of collar rings 35 are equidistantly connected to the outer side wall of the auxiliary rod 34. In order to prevent the situation of entanglement when multiple cables enter the adjustment mechanism 53, when the cables pass through the third wire wheel 401, the electric rotating table 32 drives the telescopic plate 33, the auxiliary rod 34 and the plurality of collar rings 35 to displace synchronously, so that the multiple cables passing through the third wire wheel 401 are separated to avoid entanglement with each other. And by using the telescopic function of the telescopic plate 33, when the third wire wheel 401 displaces, the telescopic plate 33 drives the auxiliary rod 34 and the collar rings 35 to move, and in cooperation with the rotation of the electric rotating table 32, it is ensured that the plurality of collar rings 35 can keep in contact with the third wire wheel 401, so that when the multiple cables are fastened respectively, they are not affected by each other.

[0068] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
