[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 piece 11, a rotating frame 2, a fixed frame 21, a rotating rod 3 and a driving structure. The sleeve rod 12 is arranged on the mounting plate 1. The cable body 6 is detachably sleeved on the sleeve rod 12. The grounding piece 11 is connected to the mounting plate 1. The rotating frame 2 is rotatably arranged on the mounting plate 1, and a mounting hole is arranged on the rotating frame 2, and a tooth groove 221 is arranged on the inner wall of the mounting hole. The fixed frame 21 is connected to the rotating frame 2 and moves synchronously with the rotating frame 2, and the fixed frame 21 has a fixed position that abuts against the cable body 6 and a evacuation position that evades the cable body 6. The rotating rod 3 is inserted into the mounting hole, and a gear 31 is arranged on the rotating rod 3, and the gear 31 can be arranged in meshing with the tooth groove 221. The driving structure is arranged between the rotating rod 3 and the mounting plate 1, and the driving structure can drive the rotating rod 3 to rotate so that the rotating frame 2 rotates.

[0036] The technical solution of this embodiment is applied, the sleeve rod 12 is arranged 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 arranged on the mounting plate 1, the fixed frame 21 is connected to the rotating frame 2 and moves synchronously with the rotating frame 2, and the fixed frame 21 can abut and cooperate with the cable body 6.

The rotating rod 3 is penetrated in the mounting hole, and a gear 31 is provided on the rotating rod 3. The gear is meshed with the tooth groove 221. The driving structure is arranged between the rotating rod 3 and the mounting plate 1, and the driving structure can drive the rotating rod 3 to rotate and drive the rotating frame 2 to rotate. Through the above-mentioned arrangement, the driving structure can drive the rotating rod 3 to rotate, and can drive the rotating frame 2 to rotate. Since the fixed frame 21 and the rotating frame 2 move synchronously, the fixed frame 21 can rotate. During installation, the cable body 6 is passed through the sleeve rod 12, and then the cable body 6 is clamped between the mounting plate 1 and the fixing frame 21 through the fixing frame 21, so that the position of the cable body 6 is more stable. In addition, the above-mentioned setting can make the operation process relatively simple. Therefore, the technical solution of this embodiment effectively solves the problem that the operation of the grounding connection in the related art is cumbersome and thus leads to greater difficulty in operation.

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

[0038] like Figures 4 to 12 As shown, in this embodiment, a slider 23, a connecting rod 231 and a moving rod 243 are arranged inside the rotating frame 2. The slider 23 is movably arranged along the length direction of the rotating frame 2 and can cooperate with the gear 31 to push and push. The moving rod 243 is movably arranged along the axis direction perpendicular to 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 slider 23 can be pushed or pulled through the connecting rod 231, so that the slider 23 pushes the gear 31 or pulls the gear 31. This linkage design makes the operation more labor-saving and is suitable for scenes that require human operation, such as the installation and removal of outdoor cable junction boxes, which reduces the physical consumption of operators and improves work efficiency.

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

[0040] like Figures 4 to 12 As shown, in this embodiment, a limit frame 25, a first limit block 253 and a second limit block 255 are further arranged inside the rotating frame 2. The first limit block 253 and the second limit block 255 are arranged at intervals along the length direction 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 is limitedly matched with the first limit block 253 or the second limit block 255. The limit design ensures the accuracy and reliability of the device during operation, and is suitable for scenes 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 between 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 telescopic rod 32 is provided on the rotating rod 3, and the spring telescopic rod 32 is located on the side of the gear 31 away from the slider 23, and the spring telescopic rod 32 pushes the gear 31. The use of the spring telescopic rod 32 enables the gear 31 to maintain good contact with the tooth groove during operation, avoiding damage to the gear 31 caused by improper operation.

[0043] like Figures 4 to 12 As shown, in this embodiment, a plurality of protruding plates are arranged on the mounting plate 1, the rotating frame 2 is located between two adjacent protruding plates, and the rotating rod 3 is arranged in the protruding plates. The design of the protruding plates not only increases the structural strength of the device, but also prevents the rotating frame from shifting during operation, and is suitable for cable junction boxes that need to be used in harsh environments, such as cable junction boxes in seaside and mountainous areas, and ensures 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, which is arranged between the protruding plate and the rotating frame 2. The use of the torsion spring 211 enables the rotating frame 2 to automatically reset after the operation is completed, which reduces the operation steps and is suitable for cable junction boxes that require rapid response, such as cable junction boxes in emergency power supply systems, thereby improving the response speed and operation efficiency of the system.

[0045] like Figure 1 As shown, in this embodiment, there are multiple rotating frames 2, multiple fixed frames 21, multiple cable bodies 6 and multiple sleeve rods 12, multiple rotating frames 2, multiple fixed frames 21, multiple cable bodies 6 and multiple sleeve rods 12 are arranged one by one, and the rotating rod 3 passes through multiple rotating frames 2. This modular design enables the device to adapt to different numbers and types of cables, and is suitable for branch boxes that need to handle multiple cables, such as cable branch boxes in data centers, which improves 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 with 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 with 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, and 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, and a fixing frame 21 is fixedly connected to the upper surface of the rotating frame 2, and a rotating rod 3 is rotatably connected to one side of the mounting plate 1, and the rotating rod 3 includes a gear 31, and a plurality of gears 31 are slidably connected to the surface of the rotating rod 3, and a rotating rod 22 is fixedly connected to one side of the rotating frame 2, and a tooth groove 221 is provided on the inner wall of the rotating rod 22, and the tooth groove 221 and the gear 31 are meshed 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, and the fixed frame 21 presses and fixes the cable body 6 sleeved on the surface of the sleeve rod 12.

[0049] Specifically, the existing connection between the cable body 6 and the grounding piece 11 is generally performed by sleeve-fitting the cable terminal grounding wire on the bolt surface at one end of the grounding piece 11, and then the cable body 6 is fixed by tightening the nut and moving it on the bolt surface. When multiple cable bodies 6 and the grounding piece 11 need to be connected, the staff needs to repeat the operation multiple times, which increases the installation time and thus causes the problem of reduced installation efficiency.

[0050] When in use, the principle is as follows: first, the grounding piece 11 is contacted and fixed to the ground, then the cable body 6 is sleeved on the sleeve rod 12 on the surface of the mounting plate 1, and then the rotating rod 3 is driven to rotate, and the rotating rod 3 drives multiple gears 31 on its surface to rotate synchronously, and the gears 31 and the tooth grooves 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 frames 21 to rotate, so that all the fixed frames 21 rotate synchronously, and the fixed frames 21 contact the cable body 6 and fix and press it on the surface of the sleeve rod 12;

[0051] When disassembly is required, the rotating rod 3 is driven to reverse, so that the plurality of rotating frames 2 can be driven to drive the fixing frame 21 to rotate, and all the cable bodies 6 can be released from the fixing operation;

[0052] The technical solution of this embodiment can control multiple fixing frames 21 to rotate synchronously and fix the cable body 6, which can reduce the time of repeated operations, improve installation efficiency, simplify the disassembly process, facilitate subsequent maintenance and replacement work, and improve convenience and efficiency.

[0053] like Figures 1 to 3 As shown, a connecting plate 13 is symmetrically fixedly connected to one side of the mounting plate 1, and the insides of the two connecting plates 13 are both rotatably connected to drive rods 5, and the two drive rods 5 are slidingly connected to the surface of the rotating rod 3, and a worm gear 51 is fixedly connected to the surface of the drive rod 5, and one end of the connecting plate 13 is rotatably connected to a worm 52, and the worm 52 and the worm wheel 51 are meshed with each other.

[0054] Specifically, when the rotating rod 3 needs to be driven to rotate, the worm 52 is rotated, and the worm 52 and the worm wheel 51 engage 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, thereby driving the rotating rod 3 to rotate synchronously.

[0055] like Figures 6 to 11As shown, the inner wall of the rotating frame 2 is slidably connected with a slider 23, one end of the slider 23 is fixedly connected with 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 with a connecting rod 231, one end of the connecting rod 231 is rotatably connected with a moving frame 24, and the interior of the moving frame 24 is slidably connected with the fixed rod 24 1, a 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 limiting frame 25, the limiting frame 25 is fixedly connected to the inner wall of the rotating frame 2, a second limiting block 255 is slidably connected to the inner lower surface of the rotating frame 2, a moving rod 243 is fixedly connected to the inside of the moving frame 24, a limiting rod 2431 is slidably connected to the inside of the moving rod 243, and a second spring 2432 is fixedly connected between the limiting rod 2431 and the inside of the moving 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 the damaged cable body 6 is replaced, the good cable body 6 may be removed from the sleeve rod 12 due to accidental contact or disassembly error. The cable body 6 that has fallen off needs to be re-docked 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 moving rod 243 at the good cable body 6 so that the moving rod 243 slides outward from the inside of the rotating frame 2 at this location, and the moving rod 243 drives the moving 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, and 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, and 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. While the connecting rod 231 rotates, the slider 23 is pulled 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 from the meshing of the tooth groove 221 with the slider 23. The tooth block drives the connecting rod 2321 to disengage from the inside of the first push rod 33. The gear 31 and the tooth groove 221 inside the rotating frame 2 below the remaining 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 support force for the rotating frame 2, so that the support frame can drive the fixed frame 21 to limit the good cable body 6.

[0060] When the number of damaged cable bodies 6 to be disassembled is greater than that of good cable bodies 6, the device can only open the rotating frame 2 corresponding to the damaged cable bodies 6 to avoid accidental contact or erroneous 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 interior of the limit frame 25 is slidably connected with 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 bodies 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, and the limiting rod 2431 is squeezed by the second limiting block 255, so that the limiting rod 2431 is stored inside the moving rod 243, and when the limiting rod 2431 passes through the second limiting block 255, release the moving rod 243, and the second limiting block 255 performs a limiting operation on 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. Because the connecting rod 2321 of 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 , Fig. 9 as well as Fig.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 inside 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, and 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, and the reset rod 4 is reset by the reset spring 42.

[0067] Working principle: first, the grounding piece 11 is contacted and fixed to the ground, 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 moving rod 243 at the good cable bodies 6 is pulled so that the moving rod 243 slides outward from the inside of the rotating frame 2 at this location, and the moving rod 243 drives the moving frame 24 to slide on the surface of the fixed rod 241 and compress the second spring 2432;

[0069] The moving rod 243 drives the limiting rod 2431 to slide toward the outside of the rotating frame 2, and 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, and 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. While the connecting rod 231 rotates, the slider 23 is pulled 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 from the meshing of the tooth groove 221 with the slider 23. The tooth block drives the connecting rod 2321 to disengage from the inside of the first push rod 33. The gear 31 and the tooth groove 221 inside the rotating frame 2 below the remaining 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 support force for the rotating frame 2, so that the support frame can drive the fixed frame 21 to limit the good cable body 6.

[0071] Find a good cable body 6 corresponding to the moving rod 243 inside the rotating frame 2, 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, and the limiting rod 2431 is squeezed by the second limiting block 255, so that the limiting rod 2431 is stored inside the moving rod 243. When the limiting rod 2431 passes through the second limiting block 255, the moving rod 243 is released, and the second limiting block 255 performs a limiting operation on 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. Because the connecting rod 2321 of 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 fixed frame 21 to rotate. The fixed 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 and improve the installation efficiency. At the same time, it simplifies the disassembly process, facilitates the subsequent maintenance and replacement work, and improves the convenience and efficiency.

[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, at this time, 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 erroneous disassembly of other good cable bodies 6, thereby reducing the re-docking and additional replacement time 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.

[0078] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
