Description

Technical Field

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

[0002] Wires and cables are wire products used to transmit electricity, signals and data. They are composed of one or more insulated wires. During the use of power transmission, distribution, electrified railways, etc., power cables will sag under the action of their own gravity and external forces, which is called sag. If the degree of sag is large, it is necessary to use a wire and cable harness tightening device to adjust the degree of cable sag.

[0003] At present, the existing device is fixed to the electric pole by setting a supporting base, and the wire is passed through the rubber ring and the wire body and pressed. The movable ring can slide to separate the wires. When it is close to the fixed ring, the internal components are inflated, so that the cables are pushed into the wire coiling groove and separated and guided. The rotating movable ring drives the wire coiling rod to wrap the cable, and the fastening ring is fixed to the plug rod. When releasing the wire, remove the fastening ring and flip the movable ring. The whole process realizes the convenient fastening and branching management of wires and cables.

[0004] However, this method is to clamp multiple cable harnesses at the same time and adjust the droop degree at the same time. The simultaneous adjustment will result in different droops and tightness of multiple cables. When one of the cables is removed, all cables must be unclamped, which will cause the cables to be released and droop. After the cables are removed, the other cables need to be retightened. This method greatly increases the complexity of tightening the fastening device. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a wire and cable harness fastening device.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wire and cable harness fastening device, comprising a main body component, the main body component comprising a fixed plate and an upper plate and a lower plate connected to the same side of the fixed plate, the upper plate is located above the lower plate, a support component is installed on the side of the fixed plate away from the upper plate, two groups of auxiliary components for guiding are symmetrically installed on the top of the upper plate, a winding component for winding is installed on the top of the upper plate and between the two groups of auxiliary components, an adjusting component is installed on the bottom of the lower plate, and the top end of the adjusting component passes through the lower plate and the upper plate.

[0007] The main body component also includes two rotating shafts symmetrically connected to the top of the upper plate, the outer side wall of each rotating shaft is connected to a first wire wheel group, and two driving motors are symmetrically installed on the bottom of the lower plate, the output ends of the two driving motors pass through the bottom of the lower plate and are connected to the driving shaft, the top of the driving shaft extends to the top of the upper plate and is connected to a second wire wheel group, the two second wire wheel groups are located between the two rotating shafts, and one of the second wire wheel groups is a group with the rotating shaft.

[0008] The adjustment component includes two connecting rods arranged on the top of the upper plate, and the outer side wall of each connecting rod is connected to a third wire wheel, and the two third wire wheels are arranged corresponding to the two groups of auxiliary components.

[0009] The winding assembly comprises a fixing frame installed on the top of the upper plate and a bearing plate installed equidistantly inside the fixing frame, and an adjustment mechanism is installed on the top of each bearing plate.

[0010] Each group of the adjustment mechanisms includes a positioning block installed on the top of the corresponding supporting plate, a positioning column is provided on the top of the positioning block, a groove is opened on the outer wall of the positioning column, a clamp is sleeved on the outer 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 a winding rod, 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, the outer walls of the two winding rods are connected to a first gear, the two first gears are arranged corresponding to the two second gears, and the first gear is meshed with the corresponding second gear.

[0011] The present invention is further configured as follows: the outer side wall of each of the winding rods is provided with a spiral groove and a spiral slide groove, and the spiral groove and the spiral slide groove are arranged in an alternating manner.

[0012] The present invention is further configured as follows: the outer side walls of the two winding rods are connected to a plate body, the two sides of the plate bodies facing away from each other are connected to a guide rod, the outer side walls of the guide rods are slidably connected to a tube body, the outer side walls of the tube body are connected to a convex rod, the end of the convex rod is inserted into the interior of the spiral groove, the outer side wall of the tube body is sleeved and connected to a fourth wire wheel, and the fourth wire wheel is arranged corresponding to the spiral wire groove.

[0013] By adopting the above technical scheme, the cable passes through the corresponding wheel bodies on the rotating shaft and the driving shaft, and the two sets of wheel bodies cooperate to transport the cable. Since the rotating shaft and the driving shaft are provided with two sets, the same cable can pass through one rotating shaft and the driving shaft, and then pass out from the other rotating shaft and the driving shaft. By adjusting the connection and separation between the rotating shaft and the corresponding wheel body and the connection and separation between the driving shaft and the corresponding wheel body, different cables can be retracted and released respectively, so as to achieve the purpose of tightening a cable separately. Multiple cables are tightened respectively by multiple sets of adjustment mechanisms, and the multiple cables do not affect each other. When the adjustment mechanism reels the same cable, the cable is first fixed, and then the reeling motor drives the second gear to rotate, and the first gear drives the corresponding reeling rod to rotate synchronously. During the rotation process, the reeling rod drives the plate body and the guide rod to rotate and displace, so that the guide rod squeezes and winds the cable, so that the cable is wound on the outer wall of the corresponding reeling rod, that is, the cable is retracted and released at both ends of the fixed point respectively, and the two ends of the same cable do not affect each other.

[0014] Before the cable is pressed into the groove, it first passes between the fourth wire wheel and the winding rod. The guide rod drives the tube body to move synchronously during the rotational displacement. The convex rod on the outer wall of the tube body is affected by the limiting effect of the spiral slide groove. When the tube body follows the rotational displacement of the guide rod, the convex rod slides on the outer wall of the guide rod. At the same time, the tube body surrounds and squeezes the cable, causing the cable to gradually wind and reel along the extension direction of the spiral groove. The two reeling rods can tighten the two ends of the cable respectively, and the cables will not be disordered, thereby improving the maintainability of the cable when it is retracted and released.

[0015] The present invention is further configured as follows: the two groups of auxiliary components each include a bracket 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, the bottom of the telescopic plate is vertically connected to an auxiliary rod, and a plurality of rings are equidistantly connected to the outer side wall of the auxiliary rod.

[0016] By adopting the above technical scheme, in order to avoid the situation where multiple cables are entangled before entering the adjustment mechanism, when the cables pass through the third wheel, the electric turntable drives the telescopic plate, the auxiliary rod and the multiple rings to move synchronously, so that the multiple cables passing through the third wheel are separated to avoid mutual entanglement, and by utilizing the telescopic function of the telescopic plate, when the third wheel is displaced, the telescopic plate drives the auxiliary rod and the ring to move, and cooperates with the rotation of the electric turntable to ensure that the multiple rings can maintain a fit with the third wheel, so that the multiple cables are not affected by each other when they are tightened separately.

[0017] The present invention is further configured as follows: two second arc grooves are symmetrically opened on the top of the upper plate, the two connecting rods are respectively inserted into the two second arc grooves, the top of the lower plate is slidably connected with a rotating rod, the outer side wall of the rotating rod is hinged with two swing plates, and the two swing plates are respectively hinged with the two connecting rods.

[0018] The present invention is further configured as follows: a mounting plate is installed at the bottom of the lower plate, guide grooves are provided at the bottom of the mounting plate and the bottom of the lower plate, the bottom of the rotating rod passes through the interior of the guide groove, 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 wall of the rotating rod.

[0019] The present invention is further configured as follows: two first arc grooves are symmetrically opened at the bottom of the lower plate, the two first arc grooves are arranged corresponding to the two second arc grooves, and each of the first arc grooves is rollingly connected to a roller, 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 scheme, the electric push rod drives the rotating rod to move inside the guide 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 groove, the swing plate pulls the connecting rod to slide inside the second arc groove, and the connecting rod drives the corresponding third wire wheel to displace, thereby adjusting the spacing between the two third wire wheels. When the connecting rod is displaced, it drives the corresponding roller to swing inside the corresponding first arc groove, thereby guiding the displacement of the connecting rod. When multiple cables are recovered, they are all passed between the driving shaft and the rotating shaft and then wound onto the outer wall of the third wire wheel for guidance. The spacing between the two third wire wheels is adjusted to an appropriate spacing and then remains stationary. The tightness of the recovered cables changes synchronously, and multiple cables are in a separated and tightened state, which prevents the cables from being accumulated in the same area, overlapping, squeezing and entangled when a large number of cables are recovered into the interior of the main assembly.

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

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

[0023] The present invention is further configured as follows: two shells are symmetrically mounted on one end of the support frame away from the fixed plate, a spring plate is inserted and connected inside each of the shells, and a rotating roller is connected between the two spring plates.

[0024] By adopting the above technical scheme, the cable is supported by the support frame and the roller to alleviate the sagging of the cable. The cable angle can also be adjusted first when the cable enters the main component to alleviate the pulling and wear of the cable when it directly enters the main component when it sags. When the cable is shaken by the external environment, the shaking force is applied to the roller and the spring plate, and the elastic force of the spring plate buffers and compensates the shaking force of the cable to prevent the cable from being broken due to excessive shaking force.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting a rotating shaft and a driving shaft, the cable passes through the corresponding wheels on the rotating shaft and the driving shaft. The two sets of wheels cooperate to transport the cable. Since two sets of rotating shafts and driving shafts are set, the same cable can pass through one rotating shaft and the driving shaft, and then pass out from the other rotating shaft and the 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, different cables can be retracted and released respectively, so as to achieve the purpose of tightening a cable separately.

[0026] (2) By setting up multiple groups of adjustment mechanisms, multiple cables are tightened respectively through multiple groups of adjustment mechanisms, and the multiple cables do not affect each other. When the adjustment mechanism reels up the same cable, the cable is first fixed, and then the reeling motor drives the second gear to rotate, and the first gear drives the corresponding reeling rod to rotate synchronously. During the rotation process, the reeling rod drives the plate body and the guide rod to rotate and displace, so that the guide rod squeezes and wraps the cable, so that the cable is wrapped around the outer wall of the corresponding reeling rod, that is, the cable is retracted and released at both ends of the fixed point respectively, and the two ends of the same cable do not affect each other.

[0027] (3) Before the cable is pressed into the groove, it first passes between the fourth wire wheel and the winding rod. The guide rod drives the tube body to move synchronously during the rotation and displacement process. The convex rod on the outer wall of the tube body is affected by the limit of the spiral groove. When the tube body follows the rotation and displacement of the guide rod, the convex rod slides on the outer wall of the guide rod. At the same time, the tube body squeezes the cable around, causing the cable to gradually wind and reel along the extension direction of the spiral groove. The two reeling rods can tighten the two ends of the cable respectively, and the cables will not be disordered, thereby improving the maintainability of the cable when it is retracted.

[0028] (4) The cable is supported by a support frame and a roller to alleviate the sagging of the cable. The cable angle can also be adjusted before the cable enters the main assembly to alleviate the pulling and wear caused by the cable sagging directly entering the main assembly. When the cable is shaken by the external environment, the shaking force is applied to the roller and the spring plate. The elastic force of the spring plate buffers and compensates the shaking force of the cable to prevent the cable from being broken due to excessive shaking force. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0042] See also Figure 1-Figure 10 , the present invention provides the following technical solutions: In the first embodiment, the existing method is to clamp multiple cable harnesses at the same time and adjust the droop degree at the same time. The simultaneous adjustment will result in different droop degrees and tightness of multiple cables. When one of the cables is removed, all cables must be unclamped, which will cause the cables to be released and droop. After the cables are removed, the other cables need to be retightened. This method greatly increases the complexity of tightening the fastening device.

[0043] For this purpose, see Figure 1 and Figure 2, a wire and cable harness fastening device, including a main body component 1, the main body component 1 includes a fixed plate 11 and an upper plate 12 and a lower plate 13 connected to the same side of the fixed plate 11, the upper plate 12 is located above the lower plate 13, the fixed plate 11, the upper plate 12 and the lower plate 13 cooperate to form a main structure, the main body component 1 also includes two rotating shafts 14 symmetrically connected to the top of the upper plate 12, the outer side wall of each rotating shaft 14 is connected to a first wire wheel group 15, and two driving motors 18 are symmetrically installed at the bottom of the lower plate 13, the output ends of the two driving motors 18 both pass 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, the two second wire wheel groups 16 are located between the two rotating shafts 14, and one of the second wire wheel groups 16 is connected to the lower plate 13. The wheel group 16 and the rotating shaft 14 are a group, the first line wheel group 15 and the second line wheel group 16 are both composed of a plurality of wheel bodies, and the wheel body in the first line wheel group 15 and the corresponding rotating shaft 14 are rotatably connected through bearings, and the wheel body in the first line wheel group 15 is locked with the rotating shaft 14 through bolts, the wheel body in the second line wheel group 16 and the corresponding driving shaft 17 are rotatably connected through bearings, and the wheel body in the second line wheel group 16 is locked with the driving shaft 17 through bolts. When the wheel body in the second line wheel group 16 is connected to the driving shaft 17, the driving motor 18 can drive the corresponding wheel body to rotate, and then drive the wheel body corresponding to the rotating shaft 14 to rotate, the wheel body corresponding to the rotating shaft 14 is locked with the rotating shaft 14, the rotating shaft 14 rotates synchronously, and the wheel body that is not locked on the driving shaft 17 and the rotating shaft 14 does not apply a rotational force.

[0044] The cable can pass through the corresponding wheel bodies on the rotating shaft 14 and the driving shaft 17, and the two sets of wheel bodies cooperate to transport the cable. Since two sets of rotating shaft 14 and driving shaft 17 are provided, the same cable can pass through between one rotating shaft 14 and driving shaft 17, and then pass out from between the other rotating shaft 14 and driving shaft 17. By adjusting the connection and separation between the rotating shaft 14 and the corresponding wheel body and the connection and separation between the driving shaft 17 and the corresponding wheel body, different cables can be retracted and released separately, so as to achieve the purpose of tightening a cable separately. If multiple cables need to be retracted and released at the same time, it is only necessary to adjust the connection between the rotating shaft 14 and the driving shaft 17 and the corresponding wheel body again.

[0045] See also Figure 1-Figure 3 A support assembly 2 is installed on one side of the fixing plate 11 away from the upper plate 12. The support assembly 2 is used to provide auxiliary support for the cable during transportation to prevent the cable from sagging when entering the main assembly 1, which may cause the cable to rub against the main assembly 1 and cause damage. The specific structure of the support assembly 2 is as follows: See also Figure 3The support assembly 2 includes a support frame 24 arranged on the side of the fixed plate 11 away from the upper plate 12, the support frame 24 is U-shaped and arranged upward, and two fixing bars 21 are symmetrically installed on the side of the fixed plate 11 away from the upper plate 12, and the two fixing bars 21 are connected to the opposite sides of the two fixing bars 21. The outer wall of each insertion rod 23 is connected to a sleeve 22, and the two sleeves 22 are connected to the support frame 24. The support frame 24 uses the insertion rod 23 to insert into the corresponding sleeve 22 for positioning. The sleeve 22 and the insertion rod 23 are both square tubes, which are prevented from rotating after connection, and a locking screw is set on the outside of the sleeve 22 to ensure that the insertion rod 23 can be stably inserted into the sleeve 22.

[0046] See also Figure 3 Two shells 25 are symmetrically installed at one end of the support frame 24 away from the fixed plate 11. 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 support frame 24 and the roller 27 to alleviate the sagging of the cable. The cable angle can also be adjusted first when the cable enters the main component 1 to alleviate the pulling and wear caused by the cable directly entering the main component 1 when the cable sags.

[0047] The roller 27 is configured to be thin in the middle and thick at both ends. When the cable contacts the roller 27, it is in a thinner position to prevent the cable from slipping. When the cable is shaken by the external environment, the shaking force is applied to the roller 27 and the spring plate 26. The elastic force of the spring plate 26 buffers and compensates the shaking force of the cable to prevent the cable from being broken due to excessive shaking force.

[0048] In the second embodiment, when the cables are recovered into the main component 1, since there are a large number of cables and the cables are piled up in the same area, the cables will bend too much after recovery and will overlap, squeeze and entangle with each other. The cables in this state cannot be released.

[0049] For this purpose, see Figure 2 , Figure 4-Figure 6 Two sets of auxiliary components 3 for guiding are symmetrically installed on the top of the upper plate 12, and an adjustment component 4 is installed at the bottom of the lower plate 13. The top of the adjustment component 4 penetrates the lower plate 13 and the upper plate 12. The adjustment component 4 is used to adjust the tightness of the cable recovery position, and the auxiliary components 3 are used to guide and organize the cables. The specific structure of the adjustment component 4 is as follows: See also Figure 2 , Figure 4-Figure 6The adjusting component 4 includes two connecting rods 48 arranged on the top of the upper plate 12, and two second arc grooves 49 are symmetrically opened on the top of the upper plate 12. The two connecting rods 48 are respectively inserted into the inside of the two second arc grooves 49. The top of the lower plate 13 is slidably connected with a rotating rod 43, and the outer side wall of the rotating rod 43 is hinged with two swing plates 47. The two swing plates 47 are respectively hinged with the two connecting rods 48. The second arc groove 49 is used to guide the connecting rod 48, and 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 components 3.

[0050] See also Figure 2 , Figure 4-Figure 6 A mounting plate 41 is installed at the bottom of the lower plate 13. Guide grooves 46 are provided at the bottom of the mounting plate 41 and the bottom of the lower plate 13. The bottom of the rotating rod 43 passes through the inside of the guide groove 46. An electric push rod 42 is installed at the bottom of the mounting 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 groove 49, the swing plate 47 pulls the connecting rod 48 to slide inside the second arc groove 49, and the connecting rod 48 drives the corresponding third wire wheel 401 to displace, thereby adjusting the distance between the two third wire wheels 401.

[0051] See also Figure 2 , Figure 4-Figure 6 Two first arc grooves 44 are symmetrically provided at the bottom of the lower plate 13. The two first arc grooves 44 are arranged corresponding to the two second arc grooves 49, and each first arc groove 44 is rollingly connected with a roller 45 inside. 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 is displaced, it drives the corresponding roller 45 to swing inside the corresponding first arc groove 44, thereby guiding the displacement of the connecting rod 48.

[0052] When multiple cables are recovered, they are all passed between the drive shaft 17 and the rotating shaft 14 and then wound onto the outer wall of the third wire wheel 401 for guidance. The spacing between the two third wire wheels 401 is adjusted to an appropriate spacing and then remains stationary. The tightness of the recovered cables changes synchronously, and the multiple cables are in a separated and tightened state, preventing a large number of cables from accumulating in the same area, overlapping, squeezing and entangled with each other when the cables are recovered into the main assembly 1.

[0053] In the third embodiment, when tightening, multiple cables are adjusted separately through the wheels 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 at the same time. If the tightness of the same cable at the two ends of the tightening device is different, adjusting one end at the same time will make one end too tight, thereby causing the cable to be pulled and broken.

[0054] For this purpose, see Figure 1 and Figure 7 A winding assembly 5 for winding is installed on the top of the upper plate 12 and between the two sets of auxiliary assemblies 3. The specific structure of the winding assembly 5 is as follows: The winding assembly 5 includes a fixing frame 51 installed on the top of the upper plate 12 and a supporting plate 52 equidistantly installed inside the fixing frame 51. An adjustment mechanism 53 is installed on the top of each supporting plate 52. The number of supporting plates 52 is the same as the number of cables passing through the fastening device. Multiple groups of adjustment mechanisms 53 can wind up multiple cables separately, and the multiple cables do not affect each other.

[0055] See also Figure 7-10 Each group of adjustment mechanisms 53 includes a positioning block 531 installed on the top of the corresponding carrier plate 52, a positioning column 532 is arranged on the top of the positioning block 531, a groove is opened on the outer wall of the positioning column 532, a clamp 534 is sleeved on the outer 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, and the protrusion 533 is arranged corresponding to the groove, both ends of the positioning column 532 are rotatably connected to the winding rod 535, and two winding motors 537 are symmetrically installed on the top of the positioning block 531, and the output end of each winding motor 537 is connected to the second gear 538. The outer side walls of each winding rod 535 are connected to a first gear 536, and the two first gears 536 are arranged corresponding to the two second gears 538. The first gear 536 is meshed with the corresponding second gear 538. The positioning block 531 is used to position the positioning column 532, and the groove on the positioning column 532 is used to clamp the cable, that is, the cable directly enters one of the adjustment mechanisms 53 after passing through one of the third wire wheels 401, and is clamped through the groove on the positioning column 532. When the cable is clamped in the groove, the clamp 534 is connected to the positioning block 531, and the protrusion 533 presses the cable in the groove, thereby fixing the cable.

[0056] In this embodiment, refer to Figure 7-10The outer walls of the two winding rods 535 are connected to a plate body 539, and the opposite sides of the two plate bodies 539 are connected to a guide rod 5303. The winding motor 537 is used to drive the second gear 538 to rotate. Since the second gear 538 is meshed with the first gear 536, when the second gear 538 rotates, the first gear 536 rotates synchronously, and the first gear 536 drives the corresponding winding rod 535 to rotate. During the rotation, the winding rod 535 drives the plate body 539 and the guide rod 5303 to rotate and displace, causing the guide rod 5303 to squeeze and wind the cable, causing the cable to be wound around the outer wall of the corresponding winding rod 535.

[0057] See also Figure 7-10 The outer wall of each winding rod 535 is provided with a spiral groove 5301 and a spiral slide groove 5302, and the spiral groove 5301 and the spiral slide groove 5302 are arranged in an alternating manner. The outer wall of the guide rod 5303 is slidably connected with a tube body 5304, and the outer wall of the tube body 5304 is connected with a convex rod 5306, and the end of the convex rod 5306 is inserted into the inner part of the spiral slide groove 5302. The outer wall of the tube body 5304 is sleeved and connected with a fourth wire wheel 5305, and the fourth wire wheel 5305 is arranged corresponding to the spiral groove 5301. Before the cable is pressed into the groove, it first passes through the fourth wire wheel. Between the wheel 5305 and the winding rod 535, the guide rod 5303 drives the tube body 5304 to move synchronously during the rotational displacement process, and the protruding rod 5306 on the outer wall of the tube body 5304 is affected by the limiting effect of the spiral groove 5302. When the tube body 5304 follows the rotational displacement of the guide rod 5303, the protruding rod 5306 slides on the outer wall of the guide rod 5303. At the same time, the tube body 5304 surrounds and squeezes the cable, causing the cable to gradually wind and wind along the extension direction of the spiral groove 5301, and the two winding rods 535 can tighten the two ends of the cable respectively.

[0058] In this embodiment, both sets of auxiliary components 3 include a bracket 31 installed on the top of the upper plate 12, an electric turntable 32 is installed at the bottom of the bracket 31, the output end of the electric turntable 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 turntable 32, an auxiliary rod 34 is vertically connected to the bottom of the telescopic plate 33, and a plurality of rings 35 are equidistantly connected to the outer wall of the auxiliary rod 34. In order to avoid the entanglement of multiple cables before entering the adjustment mechanism 53, when the cables pass through the third wire wheel 401, the electric turntable 32 drives the telescopic plate 33, the auxiliary rod 34 and the plurality of rings 35 to move synchronously, so that the multiple cables passing through the third wire wheel 401 are separated to avoid mutual entanglement, and the telescopic plate 33 can be used to retract when the third wire wheel 401 is displaced, The telescopic plate 33 drives the auxiliary rod 34 and the ring 35 to move, and cooperates with the rotation of the electric turntable 32 to ensure that the plurality of rings 35 can maintain a fit with the third wire wheel 401, so that the multiple cables are not affected by each other when they are tightened separately.
