Description

Technical Field

[0001] The invention relates to the technical field of cable spacer bars, and in particular to an adjustable cable spacer bar. Background Art

[0002] Spacers are used when laying high-voltage cables. Spacers are used to be installed between cables. Their main purpose is to separate multiple cables and limit the relative movement between cables. The setting of spacers can not only avoid collisions between cables, but also avoid the chaos of entanglement between cables caused by the influence of the external environment, and ensure the normal transmission of electricity. In order to improve the ability of the power grid to resist natural disasters, it is necessary to arrange spacers reasonably. When installing cable spacers, operators need to put multiple cables on different ends of the cable installation part respectively, and then fix multiple cables one by one on the cable spacers, which is more troublesome to operate.

[0003] A Chinese patent document with authorization announcement number CN118645944B discloses a spacer rod for erecting power cables, comprising a fixed ring, through which a guide hole is horizontally provided; the side of the movable ring is movably fitted to the fixed ring, and a plurality of movable columns are provided on the side of the movable ring, and an anti-slip disk is provided at the free end of each movable column; a plurality of spacer arms are evenly provided on the outer side of the fixed ring in a divergent shape; a fixed buckle is provided at the free end of each spacer arm, and a C-shaped first clamping portion is provided on the inner wall of the fixed buckle; a sliding member is movably connected to the spacer arm; each sliding member has a movable buckle at the outer end, the movable buckle is C-shaped, the opening direction of the movable buckle is opposite to the opening direction of the fixed buckle, and a C-shaped second clamping portion is provided on the inner wall of the movable buckle; one end of the articulated arm is hinged to the movable ring, and the other end is hinged to the inner end of the sliding member; the adjustment mechanism is used to adjust the angle of the movable ring.

[0004] In the above technical solution, after the cable is sleeved onto the clamping part, the movable ring is rotated so that all the movable fasteners can fix multiple cables at the same time. However, the above technical solution is based on the fact that the cables are evenly distributed around the cable spacer rod and the clamping part is fixed. Only then can the operator easily sleeve the cables into the clamping part. In actual operation, multiple cables are not evenly distributed due to different forces, and it is difficult for the operator to sleeve the cables into the clamping part. Summary of the invention

[0005] The present invention provides an adjustable cable spacer, aiming to solve the problem in the related art that it is inconvenient for operators to fix the cable in the clamping part of the spacer.

[0006] An adjustable cable spacer comprises: a mounting frame and a plurality of clamping parts evenly distributed along the mounting frame, the clamping parts comprising a fixed plate fixedly arranged on the mounting frame and a movable plate movably arranged on the mounting frame, the fixed plate and the movable plate are both provided with snap-fitting grooves, a push block is fixedly arranged on the mounting frame, a slide groove is provided on the movable plate, a guide assembly is installed between the push block and the slide groove, when one end of the slide groove close to the center of the mounting frame approaches the push block, the movable plate and the slide groove can rotate relative to each other, when one end of the slide groove away from the center of the mounting frame approaches the push block, the guide assembly enables the movable plate to move radially along the mounting frame, and the limit assembly enables the movable plate to slide unidirectionally toward the center of the mounting frame; A pushing ring is also coaxially rotatably provided on the mounting frame, a protrusion is fixedly provided on the movable plate, a plurality of driving blocks are evenly distributed on the pushing ring and correspond to the movable plates one by one, the driving block has a beveled edge facing the driving block and an arc edge with the same arc as the pushing ring, the pushing ring rotates to make the driving block push the protrusion to move toward the center of the mounting frame so that the two buckling grooves contact and the cable is fixed, when the two buckling grooves contact, all the driving blocks are at the same distance from the center of the mounting frame, and a connecting piece is installed between the mounting frame and the fixed ring to fix the two.

[0007] The effect is that when the operator installs the cable spacer, the operator connects the cable through the snap-fit ​​groove at the end of the movable rod. Since the movable rod can be extended and rotated, the operator can easily connect the cable to the movable rod. When all the movable rods move a certain distance toward the center of the mounting frame, the guide assembly and the limit assembly are limited and can only move toward the center of the mounting frame. The operator then rotates through the push ring. Since the movable plate is first pulled manually, each movable plate is at a different distance from the center of the mounting frame. The driving block is driven to move by the push ring, and the inner arc edge on the driving block contacts the protrusion on the movable plate, so that each movable plate is at the same distance from the center of the mounting frame. Then the mounting frame and the fixing ring are fixed by the connecting piece to complete the fixation of the cable. The operator completes the fixation of multiple cables at one time when rotating the push ring, and at the same time, the auxiliary piece is used to make the rotation of the push ring more labor-saving.

[0008] Preferably, there is a certain angle between the opening direction of the snap-fitting groove on the movable plate and the length direction of the movable plate, and the angle is between 20 degrees and 30 degrees. A baffle is rotatably arranged on the inner wall of the snap-fitting groove of the movable plate, and a torsion spring is installed between the baffle and the inner wall of the snap-fitting groove. Through the angle set between the opening direction of the snap-fitting groove on the movable plate and the length direction of the movable plate, the cable can slide into the snap-fitting groove on the movable plate more smoothly during the installation process, which improves the cable installation efficiency and reduces the possible damage to the cable. In order to ensure the stability of the cable during use, a rotating gear is added that can rotate, thereby effectively preventing the cable from accidentally slipping out of the snap-fitting groove, thereby ensuring the long-term safety and reliability of the cable.

[0009] Preferably, the guide assembly includes a slider with a V-shaped opening, a conical block fixedly arranged on the push block, and a compression spring 1, one end of the compression spring 1 is fixedly arranged in the slide groove, and the other end is connected to the slider, and the conical block is adapted to the V-shaped opening on the slider; when the conical block slides into the V-shaped groove on the slider, the operator continues to pull the movable plate so that the end of the conical block extends into the bottom of the V-shaped groove. At this time, the direction of the movable plate is corrected, and the corrected movable plate points to the center of the mounting block. Subsequently, the compression spring 1 is compressed, and when the compression spring 1 is compressed to a certain distance, the limit assembly is activated.

[0010] Preferably, the guide assembly includes a limit plate and a square plate, the limit plate is fixedly arranged on the inner walls on both sides of the end of the slide away from the center of the mounting frame, the square plate is fixedly arranged on the push block, the width of the slide formed between the two limit plates is the same as the width of the square plate, and a transition inclined surface is provided at the end of the square plate close to the push block, and a second compression spring is fixedly arranged on the inner wall of the slide, and the second compression spring extends into the slide groove; in the process of pulling the movable plate to move toward the center of the mounting plate, the square plate will pass through a transition inclined surface and enter the slide, when the square plate contacts the transition inclined surface, the position of the movable plate is corrected, and then moves toward the center of the mounting frame, and when the square plate slides in the slide, the movable plate moves toward the center of the mounting plate, and by providing the second compression spring, the movable plate is prevented from entering the limited assembly and being restricted in movement in advance due to unexpected situations such as gravity or accidental touch by the operator.

[0011] Preferably, the limit assembly includes a plurality of limit teeth and an elastic insertion rod, the plurality of limit teeth are arranged along the length direction of the movable plate, the limit teeth are right-angled triangular teeth and the inclined surface is toward the center of the mounting frame, the elastic insertion rod includes a sliding rod which slides in the up and down directions, the upper end of the sliding rod has a boss, the lower end of the sliding rod is inclined and can be inserted between any two limit teeth, a spring is installed between the sliding rod and the mounting frame, one end of the spring abuts against the lower end surface of the boss, and the other end abuts against the end of the mounting frame; when the guide assembly is activated and the movable plate is pulled to move toward the center of the mounting frame, the sliding rod is immediately inserted between two adjacent limit teeth to ensure that the movable plate moves unidirectionally toward the center of the mounting plate, and after the operator triggers the limit assembly on one of the movable rods, he can operate the movable rod when pulling the other movable rods, and the movable rod will be restricted from moving.

[0012] Preferably, the driving block has a beveled edge facing the driving block and an inner arc edge with the same arc as the pushing ring, all the inner arc edges are concentrically arranged, the driving block and the protrusion are at the same height, and the pushing ring is located above the driving block; by configuring the beveled surface and the inner curved edge, when the protruding portion contacts the beveled surface, the protruding assembly is prompted to move toward the center of the mounting frame, and when the protruding portion contacts the inner curved edge, it is ensured that the distance between all protrusions and the center of the mounting frame remains consistent.

[0013] Preferably, all driving blocks have a thrust plate facing the center of the mounting frame, and the thrust plate is located on the side away from the hypotenuse; by adjusting the thrust plate, the operator can stop the rotation when the protrusion contacts the thrust plate, which is convenient for the operator to accurately judge the rotation angle of the mounting frame.

[0014] Preferably, a rotating gear is installed on the mounting frame, an arc-shaped rack meshing with the rotating gear is provided on the pushing ring, and a slot is provided on the rotating gear; the operator inserts a long rod into the slot, and the rotating gear rotates the arc-shaped rack, thereby pushing the ring to rotate, and a lever effect is formed between the long rod and the slot, making the rotation process more labor-saving.

[0015] Preferably, the connecting member includes an upper socket provided on the push ring and a lower socket provided on the mounting frame, and a bolt is connected between the upper socket and the lower socket; when the thrust plate contacts the raised portion, the upper socket and the lower socket are aligned with each other. At this time, the operator connects the upper socket and the lower socket with the bolt, thereby achieving the connection between the push ring and the mounting frame.

[0016] Preferably, the inner wall materials of the buckling grooves of the fixed plate and the movable plate are both made of rubber material; rubber material is added to the buckling grooves of the movable plate and the fixed plate to prevent the cables from being damaged when they swing.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. In the initial state, all the movable rods are away from the center of the mounting frame, and the movable rods can be extended and swung freely. The operator first hangs the buckling grooves on the two upper movable rods on the cables, and then pulls the two movable rods to trigger the guide assembly and the limit assembly to complete the initial fixation of the mounting frame. Then the operator adjusts the length and angle of the remaining movable rods to allow other cables to enter the buckling grooves on the movable rods. The operator can easily make the cables enter the buckling grooves. Since a baffle is rotatably provided on the buckling groove, when the cable enters the buckling groove and forms a limit space between the baffle, the cable is prevented from falling out of the buckling groove; 2. When all the movable plates are in the state of being limited by the limit assembly, the operator turns the push ring to make the push block push the protrusion on the movable rod. When the operator pulls the movable rod to limit the movable rod, the distance between the end of the movable rod and the center of the mounting frame is different. The push ring is turned to make the distance between the movable rod and the center of the mounting frame the same; 3. Fix the mounting frame and the fixing ring through the connecting piece to fix multiple cables at one time. The long rod drives the rotating gear to rotate and then drives the arc-shaped rack on the pushing ring to rotate, making the pushing ring more labor-saving when rotating.

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figure 1-Figure 6 As shown, an adjustable cable spacer includes a mounting frame 1 and a plurality of clamping parts 2 evenly distributed along the mounting frame 1, the clamping part 2 includes a fixed plate 21 fixedly arranged on the mounting frame 1 and a movable plate 22 movably arranged on the mounting frame 1, and buckling grooves 23 are provided on the fixed plate 21 and the movable plate 22; when the cable spacer is installed, the movable plate 22 of the clamping part 2 is moved in a direction away from the center of the mounting frame 1, and after the cable is hung on the movable plate 22, the movable plate 22 is pulled toward the center of the mounting frame 1, and the buckling grooves 23 on the movable plate 22 and the buckling grooves 23 of the fixed plate 21 contact each other to fix the cable.

[0027] The fixed plate 21 is a support block fixedly arranged on the mounting frame 1, and the support block is arranged along the radial direction of the mounting frame 1. The buckling groove 23 is opened at the end of the support block and is opened in a direction away from the center of the mounting frame 1. The buckling groove 23 on the movable plate 22 is opened in the direction of the center of the mounting frame 1. The buckling groove 23 on the movable plate 22 and the buckling groove 23 of the fixed plate 21 are buckled with each other to fix the cable. There is a certain angle between the opening direction of the buckling groove 23 on the movable plate 22 and the length direction of the movable plate 22. The angle of the angle is between 20 degrees and 30 degrees. The movable plate 22 A baffle 26 is rotatably provided on the inner wall of the buckling groove 23, and a torsion spring 27 is installed between the baffle 26 and the inner wall of the buckling groove 23. In the initial state, the baffle 26 deflects outward from the inner wall of the buckling groove 23. When the movable plate 22 is hung on the cable, the cable passes over the baffle 26 and enters the buckling groove 23. The baffle 26 first moves toward the inner wall of the buckling groove 23 to twist the torsion spring 27. After the cable enters the buckling groove 23, the torsion spring 27 is twisted again to form a limiting space between the buckling groove 23 and the baffle 26. When the cable enters the limiting space, the cable is prevented from moving out of the buckling groove 23.

[0028] In the specific embodiment of the present invention, we take a six-split spacer rod as an example to explain in detail. Specifically, six groups of clamping parts 2 are evenly distributed around the circumference of the mounting frame 1, and six pushing blocks 24 are evenly arranged around the circumference of the mounting frame 1. The clamping parts 2 correspond to the pushing blocks 24 one by one. A sliding groove 25 is provided on the movable plate 22. In the initial state, the end of the sliding groove 25 close to the center of the mounting frame 1 contacts the pushing block 24. At this time, the width of the sliding groove 25 is designed to be larger than the width of the slider 31, so that the movable plate 22 can rotate freely. When the movable plate 22 slides in a direction away from the center of the mounting frame 1 and is connected to the cable, the movable plate 22 can still rotate freely to a certain angle. When the movable plate 22 is extended and connected to the cable, the operator does not need to pull the cable to allow the cable to enter the buckling groove 23 of the movable plate 22. The operator only needs to move the movable plate 22 to a suitable distance and adjust it to a suitable angle, so that the cable can smoothly enter the limited space of the movable plate 22. Then, the operator pulls the movable plate 22 to move it toward the center of the mounting frame 1.

[0029] In the present design, a guide assembly 3 and a limit assembly 4 are arranged between the movable plate 22 and the mounting frame 1. When the operator needs to pull the movable plate 22 toward the center of the mounting frame 1, the end of the slide groove 25 located away from the center of the mounting frame 1 will gradually approach the push block 24. At this time, the guide assembly 3 begins to play a role, guiding the movable plate 22 to move toward the center of the mounting frame 1 along the radial direction of the mounting frame 1. In the process of the operator continuously pulling the movable plate 22 toward the center of the mounting frame 1, once the trigger position of the limit assembly 4 is reached, the movable plate 22 is no longer pulled. It is worth noting that in the process of the movable plate 22 moving toward the center of the mounting frame 1, under the action of the elastic force of the cable, the closer the movable plate 22 is to the center position of the mounting frame 1, the greater the pulling force required to be applied. In order to reduce the labor intensity of the operator during the construction process, the design suggests that the operator only needs to pull the movable plate 22 to move to the position of triggering the limit assembly 4. This can effectively reduce the pulling force required to be applied, thereby reducing the difficulty of construction.

[0030] like Figure 1-Figure 5 As shown, the guide assembly 3 includes a slider 31 with a V-shaped opening, a conical block 33 fixedly arranged on the push block 24, and a compression spring 32. One end of the compression spring 32 is fixedly arranged in the slide groove 25, and the other end is connected to the slider 31. The conical block 33 is adapted to the V-shaped opening on the slider 31; when the operator pulls the movable plate 22 toward the center of the mounting frame 1, the conical block 33 will enter the V-shaped opening on the slider 31. As the operator continues to pull the movable plate 22, the end of the conical block 33 will further enter the bottom of the V-shaped opening. In this process, the direction of the movable plate 22 is accurately corrected. After the correction is completed, the direction of the movable plate 22 points to the center position of the mounting block. At this time, the compression spring 32 is compressed. After the distance of the compressed end reaches a certain length, the limit assembly 4 will be triggered.

[0031] like Figure 1-Figure 6As shown, in other embodiments of the present invention, the guide assembly 3 includes a limit plate 34 and a square plate 35. The limit plate 34 is fixedly arranged on the inner walls on both sides of the end of the slide 25 away from the center of the mounting frame 1, and the square plate 35 is fixedly arranged on the push block 24. The width of the slide formed between the two limit plates 34 is the same as the width of the square plate 35. A transition slope is provided at the end of the square plate 35 close to the push block 24. When the operator pulls the movable plate 22 toward the center of the mounting plate, the square plate 35 enters the slide through the transition slope. When the square plate 35 contacts the transition slope, the position of the movable plate 22 is corrected, thereby ensuring that it can move toward the center of the mounting frame 1 accurately. As the square plate 35 slides smoothly in the slide, the movable plate 22 also moves toward the center of the mounting plate. The whole process is smooth and precise. In an embodiment of the present invention, a second compression spring 36 is specially fixedly installed on the inner wall of the slide, and the tail ends of these second compression springs 36 extend and penetrate into the interior of the slide 25. In the initial state of the device, due to the continuous pushing action of the compression spring 2 36, the square plate 35 is firmly maintained in the internal position of the slide 25. Such a design can effectively prevent the movable plate 22 from involuntarily moving toward the center of the mounting frame 1 under the influence of gravity or due to accidents such as the operator's careless touch. When the angle of the movable plate 22 needs to be adjusted, the operator must first push the movable plate 22 to move it in a direction away from the center of the mounting plate. In this process, if the square plate 35 has penetrated into the slideway and reached a certain depth, the operator needs to further push the square plate 35 to completely enter the slideway. Only when the square plate 35 is completely in the slideway can the operator continue to adjust the angle of the movable plate 22. In addition, if the distance that the square plate 35 enters into the slideway is too deep, so that the limit assembly 4 is triggered, the operator needs to further contact and adjust the limit assembly 4 to release the limit of the movable plate 22, so as to smoothly adjust the position of the movable plate 22.

[0032] The limiting assembly 4 is composed of a plurality of limiting teeth 41 and an elastic insert rod, and these limiting teeth 41 are evenly arranged along the length direction of the movable plate 22. Each limiting tooth 41 is designed in the shape of a right triangle, and its inclined surface faces the center position of the mounting frame 1. The elastic insert rod includes a slide bar 42 that can slide in the up and down directions. The upper end of the slide bar 42 is designed with a boss, and the lower end thereof is designed in the shape of an inclined surface, so that it can be easily inserted between any two adjacent limiting teeth 41. A spring 43 is also installed between the slide bar 42 and the mounting frame 1. One end of the spring 43 abuts against the lower end surface of the boss, and the other end abuts against the end of the mounting frame 1. When the guide assembly 3 is triggered, causing the movable plate 22 to move toward the center of the mounting frame 1, the slide bar 42 will be inserted between two adjacent limiting teeth 41, so that the movable plate 22 can move unidirectionally toward the center of the mounting plate. When the operator triggers the limiting assembly 4 on one of the movable panels 22 , the movable panel 22 is restricted in its moving direction, and the operator can pull other movable panels 22 until all movable panels 22 are restricted in movement by the limiting assembly 4 .

[0033] During the installation of the cable spacer, the operator first needs to push the two upper movable plates 22 to move them to the appropriate position so that the cables can smoothly enter the limited space. Then, the operator needs to pull the movable plate 22 to ensure that the displacement of the movable plate 22 is limited by the limit assembly 4, thereby achieving unidirectional movement. In this process, the operator also needs to make corresponding adjustments to the other four movable plates 22. Since the movable plate 22 has the characteristics of adjustable direction and distance from the center of the mounting frame 1, the operator can very conveniently guide the cable into the buckle groove 23. When the operator pulls the movable plate 22 to make it close to the center of the mounting frame 1, the operator does not need to make the buckle groove 23 on the fixed plate 21 directly contact the buckle groove 23 on the movable plate 22, but only needs to ensure that the limit assembly 4 is triggered. In the process of pulling the movable plate 22, the operator does not need to apply excessive pulling force. Since the pulling force applied by the operator when pulling the movable plate 22 may be different, the distance between the movable plate 22 and the center of the mounting frame 1 after being pulled will also be different. Therefore, the subsequent operator only needs to adjust the position of the movable plate 22 to ensure that the distance between each movable plate 22 and the center of the mounting frame 1 is consistent, so as to ensure the installation accuracy and stability of the cable spacer.

[0034] A push ring 5 is coaxially rotatably provided on the mounting frame 1, and a protrusion 6 is provided on each movable plate 22. It is worth noting that the positions of these protrusions 6 on each movable plate 22 are exactly the same. A plurality of driving blocks 7 are evenly distributed on the surface of the push ring 5, and the number of these driving blocks 7 corresponds to the number of movable plates 22. When the movable plates 22 are pulled, the distance between them and the center of the mounting frame 1 will change. Since the initial position of the protrusions 6 on each movable plate 22 is the same, after the movable plate 22 is pulled, the distance between the protrusions 6 and the center of the mounting frame 1 will also be different. In order to ensure that the distance between each protrusion 6 and the center of the mounting frame 1 is consistent, the driving blocks 7 on the push ring 5 will play a role. Through their pushing action, the position of each protrusion 6 can be adjusted, thereby ensuring that they are at the same distance from the center of the mounting frame 1. By rotating the push ring 5, the driving blocks 7 push the protrusions 6 to move, so that the distance between each protrusion 6 and the center of the mounting frame 1 is the same.

[0035] The driving block 7 has a beveled edge 71 facing the driving block 7 and an inner arc edge 72 with the same arc as the pushing ring 5. All the inner arc edges 72 are concentrically arranged, the driving block 7 and the protrusion 6 are at the same height, and the pushing ring 5 is located above the driving block 7; when the operator pulls the movable plate 22 to move so that the protrusion 6 is in the inner circle of the mounting frame 1, the guide assembly 3 is triggered at this time, and the operator no longer needs to pull the movable plate 22 to move, and then drives the driving block 7 to rotate by rotating the pushing ring 5. When the driving block 7 rotates, the beveled edge 71 of the driving block 7 contacts with the protrusion 6 and moves the protrusion 6 toward the center of the mounting frame 1. When the inner arc edge 72 on the driving block 7 contacts with the protrusion 6, all the protrusions 6 are at the same distance from the center of the mounting frame 1. At this time, the buckling grooves 23 on the fixed plate 21 and the movable plate 22 buckle with each other to clamp the cables, and all the cables are at the same distance from the center of the mounting frame 1.

[0036] All driving blocks 7 have a thrust plate 73 facing the center of the mounting frame 1, and the thrust plate 73 is located on the side away from the bevel 71; when the operator rotates the push ring 5, if the thrust plate 73 contacts the protrusion 6, the operator stops rotating the push ring 5, and the operator uses this to determine the rotation angle of the push ring 5. At this time, all the protrusions 6 are at the same distance from the center of the mounting frame 1.

[0037] A rotating gear 51 is installed on the mounting frame 1, an arc-shaped rack 52 meshing with the rotating gear 51 is provided on the pushing ring 5, and a slot 53 is provided on the rotating gear 51; when the operator rotates the pushing ring 5, he can carry a long stick and insert the long stick into the slot 53 to form a lever, and the rotation of the long stick drives the rotating gear 51 to rotate and then drives the arc-shaped rack 52 to rotate, and finally the pushing ring 5 is rotated. The lever formed by the long stick makes the rotation of the pushing ring 5 more labor-saving.

[0038] A connecting piece 8 is installed between the mounting frame 1 and the fixing ring to fix the two together. The connecting piece 8 includes an upper socket 81 opened on the pushing ring 5 and a lower socket 82 opened on the mounting frame 1. When the operator rotates the pushing ring 5 to make the protrusion 6 contact with the thrust plate 73, the upper socket 81 is aligned with the lower socket 82, and the operator connects the upper socket 81 with the lower socket 82 by bolts 83.

[0039] The inner wall materials of the buckling grooves 23 of the fixed plate 21 and the movable plate 22 are both made of rubber material. When fixing the cable, the rubber material is provided to prevent the cable from being damaged when it shakes.

[0040] Working principle: In the initial state, all the movable rods are away from the center of the mounting frame 1, and the movable rods can be freely extended and swung. The operator first hangs the buckling grooves 23 on the two upper movable rods on the cables, and then pulls the two movable rods to trigger the guide assembly 3 and the limit assembly 4, so that the mounting frame 1 completes the initial fixation. Then the operator adjusts the length and angle of the remaining movable rods to make other cables enter the buckling grooves 23 on the movable rods. The operator can easily make the cables enter the buckling grooves 23; because the buckling grooves 23 are rotatably provided with baffles 26, when the cables enter the buckling grooves 23 and the baffles 26 to form a limit space, the cables are prevented from being caught. The cable falls out of the buckling groove 23. When all the movable plates 22 are in a state of being limited by the limiting assembly 4, the operator rotates the pushing ring 5 to make the pushing block push the protrusion 6 on the movable rod. When the operator pulls the movable rod to limit the movable rod, the distance between the end of the movable rod and the center of the mounting frame 1 is different. The pushing ring 5 is rotated to make the distance between the movable rod and the center of the mounting frame 1 the same. Then, the mounting frame 1 and the fixing ring are fixed by the connecting piece 8. The fixing of multiple cables is completed at one time.
