Description

Technical Field

[0001] The present invention relates to the technical field of cable spacer rods, and particularly to an adjustable cable spacer rod. Background Art

[0002] When high-voltage cables are erected, spacer rods are used. The spacer rods are installed between cables, and their main purpose is to separate multiple cables and limit the relative movement between the cables. The setting of the spacer rods can not only avoid the collision between cables but also avoid the chaos of entanglement between cables caused by the influence of the external environment, ensuring the normal transmission of electricity. To improve the ability of the power grid to resist natural disasters, it is necessary to reasonably arrange the spacer rods. When installing the cable spacer rods, the operator needs to respectively sleeve multiple cables on different ends of the cable installation part, and then fix the multiple cables to the cable spacer rods one by one, which is rather troublesome.

[0003] The Chinese patent document with the authorization announcement number CN118645944B discloses a spacer rod for erecting power cables, including a fixed ring, a guiding hole horizontally passing through the fixed ring; a movable ring is movably attached to the side of the fixed ring, and a plurality of movable columns are arranged on the side of the movable ring, and a retaining disk is arranged at the free end of each movable column; a plurality of spacer arms are evenly arranged in a divergent shape on the outer side of the fixed ring; a fixed fastening member is arranged at the free end of each spacer arm, and a C-shaped first clamping portion is arranged on the inner wall of the fixed fastening member; a sliding member is movably connected to the spacer arm; an active fastening member is arranged at the outer end of each sliding member, the active fastening member is C-shaped, the opening direction of the active fastening member is opposite to the opening direction of the fixed fastening member, and a C-shaped second clamping portion is arranged on the inner wall of the active fastening member; one end of the articulated arm is articulated with the movable ring, and the other end is articulated with the inner end of the sliding member; an adjusting mechanism is used to adjust the angle of the movable ring.

[0004] In the above technical solution, after the cable is sleeved on the clamping portion, the movable ring is rotated so that all the active fastening members fix multiple cables simultaneously. However, in the above technical solution, based on the condition that the cables are evenly distributed around the cable spacer rod and the clamping portion is fixed, the operator can conveniently sleeve the cables into the clamping portion. In the actual operation process, due to different forces on multiple cables, they are not evenly distributed, and it is very difficult for the operator to sleeve the cables into the clamping portion. Summary of the Invention

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

[0006] An adjustable cable spacer bar, comprising: a mounting frame and a plurality of clamping parts evenly distributed along the mounting frame. The clamping part includes a fixed plate fixedly arranged on the mounting frame and a movable plate movably arranged on the mounting frame. Buckling grooves are formed on both the fixed plate and the movable plate. A pushing block is fixedly arranged on the mounting frame, and a sliding groove is formed on the movable plate. A guiding component is installed between the pushing block and the sliding groove. When one end of the sliding groove close to the center of the mounting frame approaches the pushing block, the movable plate and the sliding groove can rotate relatively. When one end of the sliding groove far from the center of the mounting frame approaches the pushing block, the guiding component enables the movable plate to move along the radial direction of the mounting frame, and a limiting component enables the movable plate to slide unidirectionally towards the center of the mounting frame;

[0007] A pushing ring is also coaxially rotatably arranged on the mounting frame. A protrusion is fixedly arranged on the movable plate. A plurality of driving blocks respectively corresponding to the movable plates one by one are evenly distributed on the pushing ring. The driving block has an inclined side facing the driving block and an arc side with the same radian as the pushing ring. When the pushing ring rotates, the driving block pushes the protrusion to move towards the center of the mounting frame, so that the two buckling grooves come into contact and the cable is fixed. When the two buckling grooves come into contact, the distances of all the driving blocks from the center of the mounting frame are the same. A connecting piece for fixedly connecting the mounting frame and the fixed ring is installed between the mounting frame and the fixed ring.

[0008] The effect is as follows: When an operator installs the cable spacer bar, the cable is connected through the buckling groove at the end of the movable rod. Since the movable rod can be extended and rotated, the operator can conveniently connect the cable to the movable rod. When all the movable rods move a certain distance towards the center of the mounting frame, they are limited by the guiding component and the limiting component and can only move towards the center of the mounting frame. Then the operator rotates the pushing ring. Since the movable plate is first manually pulled, the distances of each movable plate from the center of the mounting frame are different. By driving the driving block to move through the pushing ring, the inner arc side of the driving block contacts the protrusion on the movable plate, so that the distances of each movable plate from the center of the mounting frame are the same. Then the mounting frame and the fixed ring are fixed through the connecting piece to complete the fixation of the cable. When the operator rotates the pushing ring, the fixation of multiple cables is completed at one time, and at the same time, the auxiliary piece makes it more labor-saving to rotate the pushing ring.

[0009] Preferably, there is a certain included angle between the opening direction of the buckling groove on the movable plate and the length direction of the movable plate. The angle of this included angle is between 20 degrees and 30 degrees. A baffle is rotatably arranged on the inner wall of the buckling groove of the movable plate, and a torsion spring is installed between the baffle and the inner wall of the buckling groove; Through the included angle set between the opening direction of the buckling groove on the movable plate and the length direction of the movable plate, the cable can slide into the buckling groove on the movable plate more smoothly during the installation process, improving the cable installation efficiency and reducing the possible damage to the cable. In order to ensure the stability of the cable during use, a rotating baffle is added, which can rotate and effectively prevent the cable from accidentally sliding out of the buckling groove, thus ensuring the long-term safety and reliability of the cable.

[0010] Preferably, the guiding assembly includes a slider with a V-shaped opening, a conical block fixedly arranged on the pushing block, and a first compression spring. One end of the first compression spring is fixedly arranged in the sliding groove, and the other end is connected to the slider. 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 first compression spring is compressed. When the first compression spring is compressed by a certain distance, the limiting assembly is activated.

[0011] Preferably, the guiding assembly includes a limiting plate and a square plate. The limiting plate is fixedly arranged on the inner walls of both sides at one end of the sliding groove far from the center of the mounting frame, and the square plate is fixedly arranged on the pushing block. The width of the sliding track formed between the two limiting plates is the same as the width of the square plate. A transition inclined surface is provided at the end of the square plate close to the pushing block. A second compression spring is fixedly arranged on the inner wall of the sliding track and extends into the sliding groove. During the process of pulling the movable plate towards the center of the mounting plate, the square plate will pass through a transition inclined surface and enter the sliding track. When the square plate contacts the transition inclined surface, the position of the movable plate is corrected, and then it moves towards the center of the mounting frame. When the square plate slides in the sliding track, the movable plate moves towards the center of the mounting plate. By arranging the second compression spring, it is prevented that the movable plate enters the position restricted by the limiting assembly in advance due to gravity or accidental touch by the operator.

[0012] Preferably, the limiting assembly includes a plurality of limiting teeth and an elastic insertion rod. The plurality of limiting teeth are arranged along the length direction of the movable plate. The limiting teeth are right-angled triangular teeth and the inclined surface faces the center of the mounting frame. The elastic insertion rod includes a sliding rod that slides in the up and down direction. The upper end of the sliding rod has a convex platform, and the lower end of the sliding rod is in an inclined shape and can be inserted between any two limiting 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 convex platform, and the other end abuts against the end of the mounting frame. When the guiding assembly is activated and the movable plate is pulled towards the center of the mounting frame, the sliding rod is immediately inserted between two adjacent limiting teeth to ensure that the movable plate moves unidirectionally towards the center of the mounting plate. After the operator triggers the limiting assembly on one of the movable rods, when operating other movable rods, the movable rods will be restricted from moving.

[0013] Preferably, the driving block has a hypotenuse facing the driving block and an inner arc edge with the same radian 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 inclined surface and the inner curved edge, when the protruding part contacts the inclined surface, it causes the protruding assembly to move towards the center of the mounting frame, and when the protruding part contacts the inner curved edge, it ensures that the distances between all the protrusions and the center of the mounting frame are the same.

[0014] Preferably, all driving blocks are provided with thrust plates facing the center of the mounting bracket, and the thrust plates are located on the side away from the hypotenuse; by adjusting the thrust plates, the operator can stop rotating when the protrusions contact the thrust plates, which is convenient for the operator to accurately judge the rotation angle of the mounting bracket.

[0015] Preferably, a rotating gear is mounted on the mounting bracket, an arc-shaped rack meshing with the rotating gear is formed on the pushing ring, and a slot is formed on the rotating gear; the operator inserts a long rod into the slot, rotates the rotating gear to rotate the arc-shaped rack, thereby rotating the pushing ring, and a lever action is formed between the long rod and the slot, making the rotation process more labor-saving.

[0016] Preferably, the connecting member includes an upper jack formed on the pushing ring and a lower jack formed on the mounting bracket, and a bolt is connected between the upper jack and the lower jack; when the thrust plate contacts the protruding part, the upper jack and the lower jack will be aligned with each other. At this time, the operator uses the bolt to connect the upper jack and the lower jack, thereby realizing the connection between the pushing ring and the mounting bracket.

[0017] Preferably, the inner wall materials of the buckling grooves of the fixed plate and the movable plate are both rubber materials; rubber materials are added to the buckling grooves of the movable plate and the fixed plate to prevent the cable from being damaged when it swings.

[0018] Adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0019] 1. In the initial state, all movable rods are away from the center of the mounting bracket, and the movable rods can freely extend and swing. The operator first hangs the buckling grooves on the two upper movable rods on the cable, and then pulls these two movable rods to trigger the guiding component and the limiting component to complete the preliminary fixation of the mounting bracket. Then the operator adjusts the lengths and angles of the remaining movable rods to make other cables enter the buckling grooves on the movable rods. The operator can conveniently make the cables enter the buckling grooves. Since a baffle is rotatably arranged on the buckling groove, when the cable enters the limiting space formed between the buckling groove and the baffle, the cable is prevented from falling out of the buckling groove;

[0020] 2. When all movable plates are in the state of being limited by the limiting component, the operator rotates the pushing ring to push the protrusions on the movable rod. When the operator pulls the movable rod to limit the movable rod, the distances from the end of the movable rod to the center of the mounting bracket are different. Rotating the pushing ring makes the distances from the movable rod to the center of the mounting bracket the same;

[0021] 3. The mounting bracket and the fixed ring are fixed through the connecting member, and the fixation of multiple cables is completed at one time. The rotating gear is driven to rotate by a long rod, and then the arc-shaped rack on the pushing ring is driven to rotate, making it more labor-saving when the pushing ring rotates.

Detailed Description of the Invention

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] As Figures 1 - 6 shown, an adjustable cable spacer includes a mounting bracket 1 and a plurality of clamping parts 2 evenly distributed along the mounting bracket 1. The clamping part 2 includes a fixed plate 21 fixedly arranged on the mounting bracket 1 and a movable plate 22 movably arranged on the mounting bracket 1. Fastening grooves 23 are formed on both the fixed plate 21 and the movable plate 22. When installing the cable spacer, the movable plate 22 of the clamping part 2 is moved in a direction away from the center of the mounting bracket 1. After the cable is hung on the movable plate 22, the movable plate 22 is pulled towards the center of the mounting bracket 1, and the fastening groove 23 on the movable plate 22 contacts the fastening groove 23 on the fixed plate 21 to fix the cable.

[0032] The fixed plate 21 is a support block fixedly arranged on the mounting bracket 1. The support block is arranged along the radial direction of the mounting bracket 1. The fastening groove 23 is opened at the end of the support block and faces away from the center of the mounting bracket 1. The fastening groove 23 on the movable plate 22 faces the center of the mounting bracket 1. When the fastening groove 23 on the movable plate 22 is fastened to the fastening groove 23 of the fixed plate 21, the cable is fixed. There is a certain angle between the opening direction of the fastening groove 23 on the movable plate 22 and the length direction of the movable plate 22, and the angle of this angle is between 20 degrees and 30 degrees. A baffle 26 is rotatably arranged on the inner wall of the fastening groove 23 of the movable plate 22. A torsion spring 27 is installed between the baffle 26 and the inner wall of the fastening groove 23. In the initial state, the baffle 26 deflects outward from the inner wall of the fastening groove 23. When the movable plate 22 is hung on the cable, the cable passes over the baffle 26 and then enters the fastening groove 23. The baffle 26 first moves towards the inner wall of the fastening groove 23 to twist the torsion spring 27. After the cable enters the fastening groove 23, the torsion spring 27 twists again to form a limiting space between the fastening groove 23 and the baffle 26. When the cable enters the limiting space, it is prevented from moving out of the fastening groove 23.

[0033] In a specific embodiment of the present invention, we will elaborate on it in detail by taking the six-split spacer as an example. Specifically, six groups of clamping parts 2 are evenly distributed circumferentially on the mounting bracket 1. Six push blocks 24 are evenly arranged along the circumferential direction of the mounting bracket 1. The clamping parts 2 and the push blocks 24 are in one-to-one correspondence. A sliding groove 25 is opened on the movable plate 22. In the initial state, one end of the sliding groove 25 close to the center of the mounting bracket 1 is in contact with the push block 24. At this time, the width of the sliding groove 25 is designed to be larger than the width of the sliding block 31, so that the movable plate 22 can rotate freely. When the movable plate 22 slides towards the direction away from the center of the mounting bracket 1 and is connected to the cable, the movable plate 22 can still rotate freely by a certain angle. When the movable plate 22 extends and is connected to the cable, the operator does not need to pull the cable to let the cable enter the fastening 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 limiting space of the movable plate 22. Subsequently, the operator pulls the movable plate 22 to move it towards the center of the mounting bracket 1.

[0034] In this design, a guiding component 3 and a limiting component 4 are arranged between the movable plate 22 and the mounting frame 1. When an operator needs to pull the movable plate 22 towards the center of the mounting frame 1, the end of the sliding groove 25 away from the center of the mounting frame 1 will gradually approach the push block 24. At this time, the guiding component 3 starts to function, guiding the movable plate 22 to move along the radial direction of the mounting frame 1 towards the center of the mounting frame 1. During the process that the operator continuously pulls the movable plate 22 towards the center of the mounting frame 1, once the trigger position of the limiting component 4 is reached, stop pulling the movable plate 22. It should be noted that during the process that the movable plate 22 moves towards the center of the mounting frame 1, under 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. In order to reduce the labor intensity of the operator during construction, the design suggests that the operator pull the movable plate 22 to the position where the limiting component 4 is triggered, which can effectively reduce the required pulling force and thus reduce the construction difficulty.

[0035] As Figures 1 - 5 shown, the guiding component 3 includes a slider 31 with a V-shaped opening, a conical block 33 fixedly arranged on the push block 24, and a first compression spring 32. One end of the first compression spring 32 is fixedly arranged in the sliding 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 towards 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. During this process, the orientation of the movable plate 22 is accurately corrected. After the correction is completed, the orientation of the movable plate 22 points to the center position of the mounting block. At this time, the first compression spring 32 is compressed. When the distance of its compressed end reaches a certain length, the limiting component 4 will be triggered.

[0036] As Figures 1 - 6As shown, in other embodiments of the present invention, the guiding assembly 3 includes a limiting plate 34 and a square plate 35. The limiting plate 34 is fixedly arranged on the inner walls of both sides of the end of the sliding groove 25 away from the center of the mounting frame 1, and the square plate 35 is fixedly arranged on the pushing block 24. The width of the slideway formed between the two limiting plates 34 is the same as the width of the square plate 35. A transition inclined surface is provided at the end of the square plate 35 close to the pushing block 24. When the operator pulls the movable plate 22 to move towards the center of the mounting plate, the square plate 35 enters the slideway through the transition inclined surface. When the square plate 35 contacts the transition inclined surface, it will prompt the position of the movable plate 22 to be corrected, so as to ensure that it can accurately move towards the center of the mounting frame 1. As the square plate 35 smoothly slides in the slideway, the movable plate 22 also moves towards the center of the mounting plate accordingly. The whole process is smooth and precise. In the embodiment of the present invention, compression springs II 36 are particularly fixedly installed on the inner wall of the slideway, and the tails of these compression springs II 36 extend and penetrate into the interior of the sliding groove 25. In the initial state of the device, due to the continuous pushing action of the compression springs II 36, the square plate 35 is firmly held in the inner position of the sliding groove 25. Such a design can effectively prevent the movable plate 22 from moving involuntarily towards the center direction of the mounting frame 1 under the influence of gravity or due to accidental situations such as accidental touch by the operator. When it is necessary to adjust the angle of the movable plate 22, the operator must first push the movable plate 22 to move it away from the center of the mounting plate. During this process, if the square plate 35 has penetrated deep into the slideway and reached a certain depth, then the operator also needs to further push the square plate 35 to make it completely enter the slideway. Only after the square plate 35 completely enters 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 the slideway is too deep, so that the limiting assembly 4 is triggered, then the operator also needs to further contact and adjust the limiting assembly 4 to release the limit on the movable plate 22, so as to smoothly adjust the position of the movable plate 22.

[0037] The limit component 4 is composed of a plurality of limit teeth 41 and elastic insertion rods. These limit teeth 41 are evenly arranged along the length direction of the movable plate 22. Each limit tooth 41 is designed in the shape of a right triangle, and its inclined surface faces the center position of the mounting bracket 1. The elastic insertion rod includes a sliding rod 42 that can slide in the up and down directions. The upper end of the sliding rod 42 is designed with a convex platform, and its lower end is designed in an inclined surface shape so that it can be easily inserted between any two adjacent limit teeth 41. Between the sliding rod 42 and the mounting bracket 1, a spring 43 is also installed. One end of the spring 43 abuts against the lower end surface of the convex platform, and the other end abuts against the end of the mounting bracket 1. When the guiding component 3 is triggered, causing the movable plate 22 to move towards the center of the mounting bracket 1, the sliding rod 42 will be inserted between two adjacent limit teeth 41, so that the movable plate 22 can move unidirectionally towards the center of the mounting plate. When the operator triggers the limit component 4 on one of the movable plates 22, the moving direction of this movable plate 22 is restricted, and the operator can then pull other movable plates 22 until the moving directions of all the movable plates 22 are restricted by the limit component 4.

[0038] During the installation process of the cable spacer, the operator first needs to push the two upper movable plates 22 to move them to appropriate positions so that the cable can smoothly enter the limit space. Then, the operator needs to pull the movable plate 22 to ensure that the displacement of the movable plate 22 is restricted by the limit component 4, thus realizing unidirectional movement. During this process, the operator also needs to make corresponding adjustments to the other four movable plates 22. Due to the characteristics that the movable plate 22 can adjust its direction and the distance from the center of the mounting bracket 1, the operator can very conveniently guide the cable into the buckling groove 23. When the operator pulls the movable plate 22 to make it close to the center of the mounting bracket 1, the operator does not need to make the buckling groove 23 on the fixed plate 21 directly contact the buckling groove 23 on the movable plate 22, and only needs to ensure that the limit component 4 is triggered. During the process of pulling the movable plate 22, the operator does not need to apply too much pulling force. Since the pulling force applied by the operator when pulling the movable plate 22 may be different, the distance of the movable plate 22 from the center of the mounting bracket 1 after being pulled will also be different. Therefore, subsequently, the operator only needs to adjust the position of the movable plate 22 to ensure that the distance of each movable plate 22 from the center of the mounting bracket 1 is consistent, so as to ensure the installation accuracy and stability of the cable spacer.

[0039] A pushing ring 5 is coaxially and rotatably arranged on the mounting bracket 1, and a protrusion 6 is arranged on each movable plate 22. It should be noted 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 pushing ring 5, and the number of these driving blocks 7 corresponds one by one to the number of movable plates 22. When the movable plate 22 is pulled, the distance between it and the center of the mounting bracket 1 will change. Since the initial positions of the protrusions 6 on each movable plate 22 are the same, after pulling the movable plate 22, the distances of the protrusions 6 from the center of the mounting bracket 1 will also be different. In order to ensure that the distances of each protrusion 6 from the center of the mounting bracket 1 are consistent, the driving blocks 7 on the pushing ring 5 will play a role. Through their pushing effect, the positions of each protrusion 6 can be adjusted, so as to ensure that their distances from the center of the mounting bracket 1 are the same. By rotating the pushing ring 5 to make the driving blocks 7 push the protrusions 6 to move, the distances of each protrusion 6 from the center of the mounting bracket 1 are made the same.

[0040] The driving block 7 has an inclined side 71 facing the driving block 7 and an inner arc side 72 with the same radian as the pushing ring 5. All the inner arc sides 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 bracket 1, at this time the guiding component 3 is triggered, and the operator can no longer pull the movable plate 22 to move. Then, by rotating the pushing ring 5 to drive the driving block 7 to rotate, when the driving block 7 rotates, the inclined side 71 of the driving block 7 contacts the protrusion 6 and makes the protrusion 6 move towards the center of the mounting bracket 1. When the inner arc side 72 on the driving block 7 contacts the protrusion 6, the distances of all the protrusions 6 from the center of the mounting bracket 1 are the same. At this time, the fastening grooves 23 on the fixed plate 21 and the movable plate 22 are engaged with each other to clamp the cable, and the distances of all the cables from the center of the mounting bracket 1 are also the same.

[0041] All the driving blocks 7 are provided with a thrust plate 73 facing the center of the mounting bracket 1, and the thrust plate 73 is located on the side away from the inclined side 71. When the operator rotates the pushing ring 5, if the thrust plate 73 contacts the protrusion 6, the operator stops rotating the pushing ring 5. The operator uses this to determine the rotation angle of the pushing ring 5. At this time, the distances of all the protrusions 6 from the center of the mounting bracket 1 are the same.

[0042] A rotating gear 51 is installed on the mounting bracket 1, and an arc-shaped rack 52 meshing with the rotating gear 51 is provided on the pushing ring 5. A slot 53 is provided on the rotating gear 51. When the operator rotates the pushing ring 5, a long rod can be carried. The long rod is inserted into the slot 53 to form a lever. By rotating the long rod to drive the rotating gear 51 to rotate and then drive the arc-shaped rack 52 to rotate, finally the pushing ring 5 is rotated. The lever formed by the long rod makes the rotation of the pushing ring 5 more labor-saving.

[0043] A connecting member 8 for fixedly connecting the mounting bracket 1 and the fixing ring is installed between them. The connecting member 8 includes an upper jack 81 formed on the pushing ring 5 and a lower jack 82 formed on the mounting bracket 1. When the operator rotates the pushing ring 5 so that the protrusion 6 contacts the thrust plate 73, the upper jack 81 and the lower jack 82 are aligned, and the operator can connect the upper jack 81 and the lower jack 82 with a bolt 83.

[0044] The inner wall materials of the buckling grooves 23 of the fixing plate 21 and the movable plate 22 are both rubber materials. When fixing the cable, the rubber material is provided to avoid damage to the cable when the cable shakes.

[0045] Working principle:

[0046] In the initial state, all the movable rods are away from the center of the mounting bracket 1, and the movable rods can freely extend and swing. The operator first hangs the buckling grooves 23 on the two upper movable rods on the cable, and then pulls these two movable rods to trigger the guiding assembly 3 and the limiting assembly 4, so that the mounting bracket 1 is initially fixed. Then the operator adjusts the lengths and angles of the remaining movable rods so that other cables enter the buckling grooves 23 on the movable rods, and the operator can easily make the cables enter the buckling grooves 23; since the baffle 26 is rotatably arranged on the buckling groove 23, when the cable enters the limiting space formed between the buckling groove 23 and the baffle 26, it is avoided that the cable falls out of the buckling groove 23. After all the movable plates 22 are in the state limited by the limiting assembly 4, the operator rotates the pushing ring 5 to push the protrusion 6 on the movable rod with the pushing block. When the operator pulls the movable rod to limit it, the distances from the ends of the movable rods to the center of the mounting bracket 1 are different. Rotate the pushing ring 5 to make the distances from the movable rods to the center of the mounting bracket 1 the same, and then fix the mounting bracket 1 and the fixing ring through the connecting member 8, and complete the fixing of multiple cables at one time. The long rod drives the rotating gear 51 to rotate, thereby driving the arc-shaped rack 52 on the pushing ring 5 to rotate, making it more labor-saving when the pushing ring 5 rotates.
