[0035] like Figures 1 to 5 As shown, in this embodiment, the grounding device of the cable junction box includes: a mounting plate 1, a sleeve rod 12, a cable body 6, a grounding member 11, a rotating frame 2, a fixed frame 21, a rotating rod 3, and a driving structure. The sleeve rod 12 is mounted on the mounting plate 1. The cable body 6 is detachably mounted on the sleeve rod 12. The grounding member 11 is connected to the mounting plate 1. The rotating frame 2 is rotatably mounted on the mounting plate 1. The rotating frame 2 is provided with a mounting hole, and the inner wall of the mounting hole has a tooth groove 221. The fixed frame 21 is connected to the rotating frame 2 and moves synchronously with the rotating frame 2. The fixed frame 21 has a fixed position for abutting the cable body 6 and a retracted position for avoiding the cable body 6. The rotating rod 3 is inserted into the mounting hole and is provided with a gear 31 that can mesh with the tooth groove 221. The driving structure is disposed between the rotating rod 3 and the mounting plate 1, and the driving structure can drive the rotating rod 3 to rotate, thereby rotating the rotating frame 2.

[0036] Using the technical solution of this embodiment, a sleeve rod 12 is disposed on the mounting plate 1, the cable body 6 is detachably connected to the sleeve rod 12, the grounding member 11 is connected to the mounting plate 1, the rotating frame 2 is rotatably disposed on the mounting plate 1, and the fixed frame 21 is connected to the rotating frame 2 and moves synchronously with the rotating frame 2. The fixed frame 21 is capable of abutting and cooperating with the cable body 6. The rotating frame 2 is provided with a mounting hole, the inner wall of which is provided with a tooth groove 221. The rotating rod 3 is disposed within the mounting hole and is provided with a gear 31 that meshes with the tooth groove 221. A driving structure is disposed between the rotating rod 3 and the mounting plate 1. The driving structure is capable of driving the rotating rod 3 to rotate and thereby driving the rotating frame 2 to rotate. Through the above arrangement, the driving structure can drive the rotating rod 3 to rotate and can also drive the rotating frame 2 to rotate. Since the fixed frame 21 and the rotating frame 2 move synchronously, the fixed frame 21 can also rotate. During installation, the cable body 6 is threaded onto the sleeve rod 12 and then clamped between the mounting plate 1 and the fixing bracket 21, thereby further stabilizing the position of the cable body 6. Furthermore, this arrangement simplifies the operation process. Therefore, the technical solution of this embodiment effectively solves the problem of cumbersome and difficult ground connection operations in related technologies.

[0037] like Figures 1 to 5 As shown, in this embodiment, the drive structure includes a drive rod 5, a worm gear 51, and a worm 52. The worm gear 51 is disposed on the drive rod 5, and the worm 52 is rotatably disposed on the mounting plate 1 and meshes with the worm gear 51. This design not only simplifies the operation process but also improves the durability and stability of the device, making it suitable for frequently operated cable junction boxes.

[0038] like Figures 4 to 12 As shown, in this embodiment, the interior of the rotating frame 2 is provided with a slider 23, a connecting rod 231, and a moving rod 243. The slider 23 is movably arranged along the length of the rotating frame 2 and can cooperate with the gear 31 in a pushing manner. The moving rod 243 is movably arranged in a direction perpendicular to the axis of the rotating rod 3. The first end of the connecting rod 231 is hingedly connected to the moving rod 243, and the second end of the connecting rod 231 is hingedly connected to the slider 23. When the moving rod 243 moves, the connecting rod 231 can push or pull the slider 23, so that the slider 23 pushes or pulls the gear 31. This linkage design makes operation more labor-saving and is suitable for scenarios requiring manual operation, such as the installation and removal of outdoor cable junction boxes, reducing the operator's physical exertion and improving work efficiency.

[0039] like Figures 4 to 12As shown, in this embodiment, a movable frame 24 is connected to a movable rod 243, and the movable frame 24 is hingedly connected to a connecting rod 231. The movable frame 24 is provided with a fixed rod 241 and a first spring 242. The first spring 242 is sleeved on the fixed rod 241 and is located between the movable frame 24 and the rotating frame 2 to push up the movable frame 24. The use of the first spring 242 enables the device to automatically remain in a fixed state when not in operation, preventing the loosening of cables due to improper operation. The device is suitable for cable junction boxes that require long-term stable grounding, such as cable junction boxes in industrial production, and ensures the safe operation of the power system.

[0040] like Figures 4 to 12 As shown, in this embodiment, the interior of the rotating frame 2 is further provided with a limit frame 25, a first limit block 253, and a second limit block 255. The first limit block 253 and the second limit block 255 are spaced apart along the length of the moving rod 243. The moving rod 243 is provided with a limit rod 2431 and a second spring 2432. The second spring 2432 is connected between the moving rod 243 and the limit rod 2431. The limit rod 2431 cooperates with the first limit block 253 or the second limit block 255 to limit the position. The limit design ensures the accuracy and reliability of the device during operation and is suitable for scenarios with extremely high requirements for cable grounding.

[0041] like Figures 4 to 12 As shown, in this embodiment, the slider 23 is provided with an extrusion rod 232, which can abut against the gear 31. Through the cooperation of the extrusion rod 232 and the gear 31, the gear 31 can be pushed up, making the cable more stable during the grounding process.

[0042] like Figures 4 to 12 As shown, in this embodiment, a spring-loaded telescopic rod 32 is provided on the rotating rod 3. The spring-loaded telescopic rod 32 is located on the side of the gear 31 away from the slider 23. The spring-loaded telescopic rod 32 pushes the gear 31. The use of the spring-loaded telescopic rod 32 ensures that the gear 31 maintains good contact with the tooth groove during operation, thereby preventing damage to the gear 31 due to improper operation.

[0043] like Figures 4 to 12 As shown, in this embodiment, a plurality of protruding plates are provided on the mounting plate 1, the rotating frame 2 is positioned between two adjacent protruding plates, and the rotating rod 3 is disposed within the protruding plates. The protruding plate design not only increases the structural strength of the device but also prevents the rotating frame from shifting during operation. This design is suitable for cable junction boxes used in harsh environments, such as coastal and mountainous areas, ensuring the stability and durability of the device.

[0044] like Figures 4 to 12As shown, in this embodiment, the cable junction box grounding device further includes a torsion spring 211 disposed between the protruding plate and the turret 2. The use of the torsion spring 211 enables the turret 2 to automatically reset after an operation is completed, reducing the number of operating steps. This makes it suitable for cable junction boxes requiring rapid response, such as those in emergency power supply systems, and improves system response speed and operational efficiency.

[0045] like Figure 1 As shown, in this embodiment, multiple turrets 2, fixed frames 21, cable bodies 6, and sleeve rods 12 are provided. Multiple turrets 2, multiple fixed frames 21, multiple cable bodies 6, and multiple sleeve rods 12 are provided in a one-to-one correspondence, and the rotating rod 3 is inserted into multiple turrets 2. This modular design allows the device to adapt to different quantities and types of cables and is suitable for junction boxes that need to handle multiple cables, such as cable junction boxes in data centers, improving the versatility and flexibility of the device.

[0046] In other embodiments, Figures 1 to 12 As shown, the technical solution of this embodiment adopts the following technology: a grounding device for a cable junction box: comprising a mounting plate 1, a grounding piece 11 and a cable body 6, one side of the mounting plate 1 is fixedly connected to a plurality of sleeve rods 12, one end of the cable body 6 is sleeved on the surface of the sleeve rod 12, and the back side of the mounting plate 1 is fixedly connected to a plurality of grounding pieces 11;

[0047] A fixing mechanism for fixing the cable body 6 is provided on one side of the mounting plate 1. The fixing mechanism includes a plurality of rotating frames 2 rotatably connected to one side of the mounting plate 1 and located on the bottom side of the sleeve rod 12. The upper surface of the rotating frames 2 is fixedly connected to a fixing frame 21. A rotating rod 3 is rotatably connected to one side of the mounting plate 1. The rotating rod 3 includes a gear 31. Several gears 31 are slidably connected to the surface of the rotating rod 3. A rotating rod 22 is fixedly connected to one side of the rotating frame 2. The inner wall of the rotating rod 22 is provided with a tooth groove 221, and the tooth groove 221 and the gear 31 are engaged with each other.

[0048] By rotating the rotating rod 3, the rotating rod 3 drives the gear 31 to rotate, and the gear 31 engages with the tooth groove 221, so that the rotating rod 22 drives the rotating frame to rotate, and the rotating frame 2 drives the fixed frame 21 to rotate. The fixed frame 21 presses and fixes the cable body 6 sleeved on the surface of the sleeve rod 12.

[0049] Specifically, the conventional connection between the cable body 6 and the grounding member 11 is generally performed by sleeve-fitting the cable terminal grounding wire onto the surface of a bolt at one end of the grounding member 11, and then tightening the nut and moving it on the surface of the bolt to fix the cable body 6. When multiple cable bodies 6 and the grounding member 11 need to be connected, the operator needs to repeat the operation multiple times, which increases the installation time and thus reduces the installation efficiency.

[0050] In use, its principle is as follows, first, the ground contact and fixed ground 11, then the cable body 6 is sleeved on the surface of the mounting plate 1 sleeve rod 12, then drive the rotation of the rod 3, the rotation of the rod 3 surface of the plurality of gear 31 synchronous rotation, gear 31 and tooth groove 221 meshing with each other, so that the rotating rod 22 follow the gear 31 synchronous rotation, rotating rod 22 drive a plurality of rotating frame 2 synchronous rotation, so that a plurality of rotating frame 2 drive fixed frame 21 rotation, so that all the fixed frame 21 are synchronous rotation, fixed frame 21 and cable body 6 contact and fixed compression on the surface of the sleeve rod 12;

[0051] When it needs to be removed, drive the reverse rotation of the rod 3, that is, drive a plurality of rotating frame 2 drive fixed frame 21 rotation, that is, all the cable body 6 is removed from the fixed operation;

[0052] The technical scheme of the embodiment can control the synchronous rotation of a plurality of fixed frame 21 and the fixed operation of the cable body 6, which can reduce the time of repeated operation, improve the installation efficiency, simplify the disassembly process, facilitate the subsequent maintenance and replacement work, and improve the convenience efficiency.

[0053] As shown in Figures 1 to 3 The mounting plate 1 is symmetrically connected with a connecting plate 13 on one side, and the inside of the two connecting plates 13 is rotatably connected with a drive rod 5. The surface of the drive rod 5 is fixedly connected with a worm gear 51, and one end of the connecting plate 13 is rotatably connected with a worm 52. The worm 52 and the worm gear 51 are meshed with each other.

[0054] Specifically, when the drive rod 3 needs to be driven to rotate, the worm 52 is rotated, and the worm 52 and the worm gear 51 are meshed with each other, so that the worm gear 51 drives the drive rod 5 in the inner wall to rotate synchronously, and the drive rod 5 drives the rotating rod 3 in the inside to rotate synchronously, that is, the rotating rod 3 is driven to rotate synchronously.

[0055] As shown in Figures 6 to 11As shown, the inner wall of the rotating frame 2 is slidably connected to a slider 23, one end of the slider 23 is fixedly connected to an extrusion rod 232, one side of the extrusion rod 232 is in contact with one side of the gear 31, the rotating rod 3 also includes a spring telescopic rod 32, the fixed end of the spring telescopic rod 32 is fixedly connected to the surface of the rotating rod 3, the movable end of the spring telescopic rod 32 is fixedly connected to one side of the gear 31, one side of the slider 23 is rotatably connected to a connecting rod 231, one end of the connecting rod 231 is rotatably connected to the moving frame 24, and the interior of the moving frame 24 is slidably connected to the fixed rod 24 1. The fixed rod 241 is fixedly connected to the inner wall of the rotating frame 2, and a first spring 242 is fixedly connected between the fixed rod 241 and the rotating frame 2. The rotating frame 2 includes a limit frame 25, which is fixedly connected to the inner wall of the rotating frame 2. A second limit block 255 is slidably connected to the inner lower surface of the rotating frame 2. The interior of the movable frame 24 is fixedly connected to the movable rod 243, and the interior of the movable rod 243 is slidably connected to the limit rod 2431, and a second spring 2432 is fixedly connected between the limit rod 2431 and the interior of the movable rod 243.

[0056] Specifically, when the cable body 6 is damaged, it is necessary to remove the damaged cable body 6 from the surface of the sleeve rod 12 and replace it. Since the rotating frame 2 is opened or pressed synchronously during use, when replacing the damaged cable body 6, an accidental collision or disassembly error may occur, causing the good cable body 6 to be removed from the sleeve rod 12. The cable body 6 that has fallen off needs to be re-docking later, which increases the replacement time and thus causes a decrease in replacement efficiency.

[0057] When the number of damaged cable bodies 6 to be disassembled is greater than that of good cable bodies 6, the method is as follows: pull the movable rod 243 at the good cable body 6 so that the movable rod 243 slides outward from the inside of the rotating frame 2 at this location, and the movable rod 243 drives the movable frame 24 to slide on the surface of the fixed rod 241 and compress the second spring 2432;

[0058] The moving rod 243 drives the limiting rod 2431 to slide toward the outside of the rotating frame 2. The limiting rod 2431 moves to the second limiting block 255 and is squeezed by the second limiting block 255, so that the limiting rod 2431 is received inside the moving rod 243 and squeezes the second spring 2432. Then, the limiting rod 2431 passes through the second limiting block 255. After the moving rod 243 is released, the limiting rod 2431 is limited by the second limiting block 255.

[0059] At the same time, the movable frame 24 drives the connecting rod 231 to rotate. The connecting rod 231 rotates and pulls the slider 23 to slide on the inner wall of the rotating frame 2, so that the slider 23 drives the extruding rod 232 to slide to one side of the movable frame 24. At this time, the spring telescopic rod 32 pushes the gear 31 to slide on the surface of the rotating rod 3. Because one end of the rotating rod 3 is limited by the inner wall of the driving rod 5, the rotating rod 3 does not slide. At the same time, the gear 31 slides and disengages the meshing of the tooth groove 221 with the tooth block, and the connecting rod 2321 disengages from the inside of the first push rod 33. The gear 31 and the tooth groove 221 inside the rotating frame 2 below the damaged cable body 6 continue to mesh. Therefore, when the rotating rod 3 is driven to rotate, the rotating rod 3 only drives the rotating frame 2 below the damaged cable body 6 to rotate. At the same time, torsion springs 211 are fixedly connected between the two sides of the rotating frame 2 and the mounting plate 1. The torsion springs 211 provide supporting force for the rotating frame 2, so that the supporting frame can drive the fixed frame 21 to limit the good cable body 6;

[0060] When the number of damaged cable bodies 6 is greater than that of good cable bodies 6 for disassembly, this device can only open the rotating frame 2 corresponding to the damaged cable bodies 6, avoiding accidental contact or incorrect disassembly of other good cable bodies 6, thereby reducing the re-docking and additional replacement time caused by misoperation.

[0061] like Figures 6 to 11 As shown, the rotating rod 3 includes a first push rod 33, which is fixedly connected to the outer wall of the rotating rod 3, and there is a gap between the first push rod 33 and the gear 31. The rotating rod 3 also includes a first extrusion spring 34, which is fixedly connected between one end of the rotating rod 3 and the inner wall of the driving rod 5. The internal sliding connection of the limit frame 25 is a second limit block 255.

[0062] Specifically, when the number of good cable bodies 6 is greater than the number of damaged cable bodies 6, the method of use is as follows: find the moving rod 243 inside the rotating frame 2 corresponding to the good cable body 6, press the moving rod 243, so that the moving rod 243 slides toward the inside of the rotating frame 2, and the moving rod 243 drives the limiting rod 2431 to slide synchronously. The limiting rod 2431 is squeezed by the second limiting block 255, so that the limiting rod 2431 is received inside the moving rod 243. After the limiting rod 2431 passes the second limiting block 255, the moving rod 243 is released, and the second limiting block 255 limits the limiting rod 2431.

[0063] The moving rod 243 drives the moving frame 24 to slide toward the inner side of the rotating frame 2, and the rotating frame 2 drives the connecting rod 231 to rotate. The connecting rod 231 pushes the slider 23 to move synchronously. The slider 23 slides to one side of the tooth groove 221. The slider 23 pushes the gear 31 here to move through the extrusion rod 232. Because the gear 31 is limited by the spring telescopic rod 32, the gear 31 pushes the rotating rod 3 to slide inside the driving rod 5 and squeezes the first extrusion spring 34. At the same time, the slider 23 drives the connecting rod 2321 to push the first push rod 33. The first push rod 33 slides synchronously with the rotating rod 3. When the rotating rod 3 slides, the surface of the rotating rod 3 The first push rod 33 will move, so that the gear 31 at the corresponding position of the good cable body 6 contacts the first push rod 33, and the first push rod 33 pushes the gear 31 to slide synchronously, so that the gear 31 is out of engagement with the tooth groove 221, and then drives the rotating rod 3 to rotate. Since the connecting rod 2321 on the side wall of the slider 23 corresponding to the damaged cable body 6 is located inside the first push rod 33, the rotating rod 3 drives the first push rod 33 to rotate, and the first push rod 33 drives the slider 23 to rotate. The slider 23 drives the damaged cable body 6 here to rotate synchronously through the moving rod 243, and the damaged cable body 6 can be removed.

[0064] When the number of good cable bodies 6 is greater than the number of damaged cable bodies 6 , the damaged cable bodies 6 can be replaced by adjusting the rotating racks 2 corresponding to the smaller number of damaged cable bodies 6 to rotate.

[0065] like Figure 3 、 Figure 9 as well as Figure 12 As shown, a reset rod 4 is slidably connected to one side of the connecting plate 13, and a plurality of cone blocks 41 are fixedly connected to the surface of the reset rod 4. A reset spring 42 is fixedly connected between one end of the reset rod 4 and one side of the connecting plate 13. A protrusion 251 is slidably connected to the inside of the limit frame 25, and a third spring 252 is fixedly connected between one side of the protrusion 251 and the limit frame 25. A first limit spring 254 is fixedly connected between the first limit block 253 and the inner wall of the limit frame 25, and a second limit spring 256 is fixedly connected between the second limit block 255 and the inner wall of the limit frame 25. A push plate 257 is fixedly connected to one side of the protrusion 251. A plurality of second push rods 35 are slidably connected to the outer wall of the rotating rod 3, and a second extrusion spring 36 is fixedly connected between the surface of the second push rod 35 and the inner wall of the rotating rod 3.

[0066] Specifically, when the cable body 6 is replaced, the moving rod 243 is limited by the first limit block 253 or the second limit block 255. For the convenience of subsequent use, after the rotating frame 2 is reset, the reset rod 4 can be pushed, so that the reset rod 4 squeezes the reset spring 42 and the cone block 41 moves. The cone block 41 squeezes the second push rod 35, so that the second push rod 35 squeezes the push plate 257, and the push plate 257 drives the protrusion 251 to move, so that the protrusion 251 slides on the inner wall of the limit frame 25 and squeezes the third spring 252. At this time, the second extrusion spring 36 drives the second limit block 255 to move upward, and the first extrusion spring 34 drives the first limit block 253 to move upward, so that the first limit block 253 or the second limit block 255 releases the limit on the limit rod 2431. At this time, the moving rod 243 can be reset by the first spring 242, and the reset rod 4 is released. The reset rod 4 is reset by the reset spring 42.

[0067] Working principle: first, the grounding piece 11 is brought into contact with the ground and fixed, then the cable body 6 is sleeved on the sleeve rod 12 on the surface of the mounting plate 1, and the worm 52 is rotated. The worm 52 and the worm wheel 51 are meshed with each other, so that the worm wheel 51 drives the driving rod 5 on its inner wall to rotate synchronously, and the driving rod 5 then drives the rotating rod 3 inside it to rotate synchronously, and the rotating rod 3 drives multiple gears 31 on its surface to rotate synchronously, and the gear 31 and the tooth groove 221 are meshed with each other, so that the rotating rod 22 rotates synchronously with the gear 31, and the rotating rod 22 drives several rotating frames 2 to rotate synchronously, so that several rotating frames 2 drive the fixed frame 21 to rotate, so that all the fixed frames 21 rotate synchronously, and the fixed frame 21 contacts the cable body 6 and fixes and presses it tightly on the surface of the sleeve rod 12;

[0068] When the number of damaged cable bodies 6 to be disassembled is greater than that of good cable bodies 6, the movable rod 243 at the good cable bodies 6 is pulled, so that the movable rod 243 slides outward from the inside of the rotating frame 2 at this location. The movable rod 243 drives the movable frame 24 to slide on the surface of the fixed rod 241 and compresses the second spring 2432.

[0069] The moving rod 243 drives the limiting rod 2431 to slide toward the outside of the rotating frame 2. The limiting rod 2431 moves to the second limiting block 255 and is squeezed by the second limiting block 255, so that the limiting rod 2431 is received inside the moving rod 243 and squeezes the second spring 2432. Then, the limiting rod 2431 passes through the second limiting block 255. After the moving rod 243 is released, the limiting rod 2431 is limited by the second limiting block 255.

[0070] At the same time, the movable frame 24 drives the connecting rod 231 to rotate. The connecting rod 231 rotates and pulls the slider 23 to slide on the inner wall of the rotating frame 2, so that the slider 23 drives the extruding rod 232 to slide to one side of the movable frame 24. At this time, the spring telescopic rod 32 pushes the gear 31 to slide on the surface of the rotating rod 3. Because one end of the rotating rod 3 is limited by the inner wall of the driving rod 5, the rotating rod 3 does not slide. At the same time, the gear 31 slides and disengages the meshing of the tooth groove 221 with the tooth block, and the connecting rod 2321 disengages from the inside of the first push rod 33. The gear 31 and the tooth groove 221 inside the rotating frame 2 below the damaged cable body 6 continue to mesh. Therefore, when the rotating rod 3 is driven to rotate, the rotating rod 3 only drives the rotating frame 2 below the damaged cable body 6 to rotate. At the same time, torsion springs 211 are fixedly connected between the two sides of the rotating frame 2 and the mounting plate 1. The torsion springs 211 provide supporting force for the rotating frame 2, so that the supporting frame can drive the fixed frame 21 to limit the good cable body 6;

[0071] Find the cable body 6 that is in good condition and corresponds to the movable rod 243 inside the rotating frame 2. Press the movable rod 243 so that the movable rod 243 slides toward the inside of the rotating frame 2. The movable rod 243 drives the limiting rod 2431 to slide synchronously. The limiting rod 2431 is squeezed by the second limiting block 255 so that the limiting rod 2431 is stored inside the movable rod 243. After the limiting rod 2431 passes the second limiting block 255, release the movable rod 243. The second limiting block 255 limits the limiting rod 2431.

[0072] The moving rod 243 drives the moving frame 24 to slide toward the inner side of the rotating frame 2, and the rotating frame 2 drives the connecting rod 231 to rotate. The connecting rod 231 pushes the slider 23 to move synchronously. The slider 23 slides to one side of the tooth groove 221. The slider 23 pushes the gear 31 here to move through the extrusion rod 232. Because the gear 31 is limited by the spring telescopic rod 32, the gear 31 pushes the rotating rod 3 to slide inside the driving rod 5 and squeezes the first extrusion spring 34. At the same time, the slider 23 drives the connecting rod 2321 to push the first push rod 33. The first push rod 33 slides synchronously with the rotating rod 3. When the rotating rod 3 slides, the surface of the rotating rod 3 The first push rod 33 will move, so that the gear 31 at the corresponding position of the good cable body 6 contacts the first push rod 33, and the first push rod 33 pushes the gear 31 to slide synchronously, so that the gear 31 is out of engagement with the tooth groove 221, and then drives the rotating rod 3 to rotate. Since the connecting rod 2321 on the side wall of the slider 23 corresponding to the damaged cable body 6 is located inside the first push rod 33, the rotating rod 3 drives the first push rod 33 to rotate, and the first push rod 33 drives the slider 23 to rotate. The slider 23 drives the damaged cable body 6 here to rotate synchronously through the moving rod 243, and the damaged cable body 6 can be removed.

[0073] After the rotating frame 2 has been reset, the reset rod 4 can be pushed, so that the reset rod 4 squeezes the reset spring 42 and the cone block 41 moves. The cone block 41 squeezes the second push rod 35, so that the second push rod 35 squeezes the push plate 257. The push plate 257 drives the protrusion 251 to move, so that the protrusion 251 slides on the inner wall of the limit frame 25 and squeezes the third spring 252. At this time, the second extrusion spring 36 drives the second limit block 255 to move upward, and the first extrusion spring 34 drives the first limit block 253 to move upward, so that the first limit block 253 or the second limit block 255 releases the limit on the limit rod 2431. At this time, the moving rod 243 can be reset by the first spring 242, and the reset rod 4 is released. The reset rod 4 is reset by the reset spring 42.

[0074] The beneficial effects of the technical solution of this embodiment are as follows:

[0075] By providing a rotating rod 3 and a rotating frame 2, the rotating rod 3 drives the rotating frame 2 to rotate, and the rotating frame 2 can drive the fixing frame 21 to rotate. The fixing frame 21 can rotate synchronously and fix all the cable bodies 6 installed on the surface of the sleeve rod 12, which can reduce the time of repeated operations, improve the installation efficiency, simplify the disassembly process, and facilitate subsequent maintenance and replacement work, making it convenient and efficient.

[0076] When the number of damaged cable bodies 6 that need to be disassembled is greater than the number of good cable bodies 6, by driving the moving rod inside the rotating frame 2 at the corresponding good cable body 6 to pull outward, the gear 31 here can be driven to move and release the engagement with the tooth groove 221. Then, when the rotating rod 3 rotates, only the damaged cable body 6 can be opened. At the same time, when the number of good cable bodies 6 is greater than the number of damaged cable bodies 6, the moving rod inside the rotating frame 2 at the corresponding damaged cable body 6 is driven to push the rod inward, and the rotating frame 2 at the corresponding damaged part can be driven to rotate synchronously alone, thereby avoiding accidental contact or incorrect disassembly of other good cable bodies 6, thereby reducing the time for re-docking and additional replacement caused by misoperation.

[0077] By providing a reset rod 4, when the fixing frame 21 is fully reset, the reset rod 4 can be pressed to drive all the moving rods to the initial position, which is convenient for subsequent use, avoids the operation time caused by resetting the moving rods individually, and increases the convenience and efficiency of the installation of the cable terminal grounding wire.
