Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness fixing technology, and more specifically, to an automotive wiring harness fixing device. Background Technology

[0002] In existing technologies, automotive wiring harness fixing devices, as important supporting components of automotive electrical systems, are widely used in the wiring harness layout and fixing operations of various vehicles. They are primarily used to securely fix power harnesses, signal harnesses, communication harnesses, and various functional harnesses inside the vehicle to their installation locations such as the vehicle body frame, chassis structure, and dashboard frame. This ensures that the wiring harnesses maintain a stable installation state during vehicle operation, preventing them from loosening or falling off due to vehicle bumps and vibrations, which could affect the normal operation of the electrical system. In practical applications, because automotive wiring harnesses vary significantly in diameter, number, and material structure among different vehicle models and installation locations, wiring harness fixing devices need to be adaptable to different needs. Different specifications of wire harnesses require compatible clamping to achieve reliable fixation. However, existing automotive wire harness fixing devices typically use fixed-diameter structures or pre-sized clamping slots for wire harness fixation, which cannot flexibly adjust the clamping according to the actual diameter of the wire harness being installed. This results in loose clamping and insecure fixation for wire harnesses with smaller diameters, while for wire harnesses with larger diameters, they cannot be installed smoothly or are clamped too tightly, compressing the wire harness sheath. This not only affects the universal compatibility of the wire harness fixing device with different specifications of wire harnesses, reducing installation efficiency, but also makes it easier for the wire harness to loosen and shift or for the wire harness sheath to be damaged or broken during vehicle operation due to improper clamping force, affecting the reliability of electrical connections and increasing the risk of circuit faults.

[0003] Secondly, while some existing automotive wiring harness fixing devices achieve flexible clamping and fixing of automotive wiring harnesses of different diameters by incorporating adjustable components on the device body, allowing installers to adjust the opening and closing range of the clamping structure to obtain appropriate clamping force and ensure secure wiring harness fixing, the wiring harness clamping and adjustment structure design of these devices is relatively simple and usually lacks structural stability. In actual automotive use, the adjusted wiring harness fixing device is easily affected by impacts and vibrations from road bumps, continuous vibrations transmitted from engine operation, and sudden changes in road conditions. External forces such as the inertial force generated by acceleration and sudden braking, and the downward pull exerted by the weight of the wiring harness itself, can cause the internal adjusting components of the properly adjusted wiring harness fixing device to shift and loosen. This results in a weakening of the clamping force of the clamping mechanism on the wiring harness, a shift in the clamping position, and loosening and shaking of the originally securely fixed wiring harness. Consequently, the wiring harness cannot maintain a stable installation state during vehicle operation. This not only reduces the reliability of the wiring harness fixing and affects the stable operation of the vehicle's electrical system, but may also cause damage to the wiring harness sheath or even short circuits due to friction and wear between the loosened wiring harness and surrounding metal parts, seriously affecting vehicle driving safety.

[0008] The present invention is further configured such that a guide rod is connected to one side of the guide block, the guide spring is movably sleeved on the outside of the guide rod, a guide hole is opened in the adapter block, and one end of the guide rod slides into the guide hole.

[0009] The present invention is further configured such that a support spring is movably sleeved on the outside of the support rod, one end of the support spring is connected to the limiting sleeve, and the other end of the support spring abuts against one side of the rotating plate.

[0010] The present invention is further configured such that a guide rod is connected to one side of the tensioning plate, a guide groove is provided in the mating block, one end of the guide rod is slidably inserted into the guide groove, and a plurality of rubber strips are fixedly provided on the inner side of the tensioning plate.

[0011] The present invention is further configured such that the two sliding sleeves are designed to face each other, and the outer wall of the sliding sleeve is movably connected to the inner wall of the control sleeve by threads, and the threads at both ends of the inner wall of the control sleeve are designed to be symmetrical.

[0012] The present invention is further configured such that a collaborative spring is movably sleeved on the outer side of the collaborative rod, and the two ends of the collaborative spring are respectively connected to the collaborative plate and the collaborative seat.

[0013] The present invention is further configured such that a sliding groove is provided on the outer side of the buckle sleeve, a sliding block is slidably disposed in the sliding groove, and the sliding block is fixedly disposed on the inner side of the limiting sleeve.

[0014] Compared with the prior art, the present invention provides an automotive wiring harness fixing device, which has the following advantages: 1. By setting up a mating plate, mating block, and tightening plate within the snap-fit ​​sleeve, along with a spring, guide rod, and guide groove, the system achieves flexible adjustment and clamping functionality based on the diameter of the automotive wiring harness. During use, rotating the control sleeve forward causes the sliding sleeve to slide towards the center via a threaded connection, driving the moving sleeve to push the mating block towards the center. Simultaneously, the mating block drives the mating plate to slide along the inclined mating groove, causing the mating block to move outwards to its outermost position via the guide rod and guide groove. After adjustment, the wiring harness to be connected and fixed is inserted into the snap-fit ​​sleeve, ensuring the connection point of the two wiring harnesses is located in the center of the snap-fit ​​sleeve. Reverse rotation of the control sleeve causes the sliding sleeve to slide in the opposite direction, driving the moving sleeve to push the mating block in the opposite direction. The mating block then drives the mating plate to slide in the opposite direction along the mating groove, causing the mating block to move through the guide rod and spring. The moving clamping plate converges inward, adjusting the convergence amplitude according to the outer diameter of the wire harness and clamping the outer wall of the wire harness to achieve a proper fit and fixation. This effectively solves the problems of existing automotive wire harness fixing devices that use fixed-diameter structures or preset-sized clamping slots for wire harness fixing, which cannot flexibly adjust the clamping according to the actual diameter of the installed cables. This results in loose clamping and insecure fixing of thinner diameter wire harnesses, while thicker diameter wire harnesses cannot be installed smoothly or are clamped too tightly, compressing the wire harness sheath. This affects the universal compatibility of the wire harness fixing device with different specifications of wire harnesses, reduces installation efficiency, and easily causes the wire harness to loosen or shift or the wire harness sheath to be damaged or broken during vehicle operation due to improper clamping force, affecting the reliability of electrical connections and increasing the risk of circuit faults. This improves the flexible adaptability of the wire harness fixing device to wire harnesses of different diameters and the reliability of clamping and fixing.

[0015] 2. By setting a locking mechanism for the control sleeve using a limiting sleeve in conjunction with a rotating plate, and a limiting mechanism for the coordinating seat using a coordinating rod in conjunction with a coordinating groove, combined with a support structure for the limiting sleeve using a support rod in conjunction with a rotating hole, a stable locking system for the wire harness clamping and adjusting structure is constructed. After clamping, the support rod supports the limiting sleeve to one side of the rotating plate and, in conjunction with the sliding block and sliding groove, limits the limiting sleeve to prevent it from moving. The inner wall of the limiting sleeve then limits the outer wall of the coordinating plate to prevent the coordinating plate and coordinating rod from sliding outward. The coordinating rod, in conjunction with the coordinating groove, forms a limit to prevent the coordinating seat and control sleeve from rotating unexpectedly. The synergistic effect of multiple locking mechanisms ensures the stable fixation of the adjusted wire harness clamping structure, effectively preventing the wire harness fixing device from being damaged by road bumps during actual vehicle use. External forces such as the impact vibrations generated by winches, the continuous vibrations transmitted by the engine, the inertial forces generated by rapid acceleration and braking, and the downward pull exerted by the weight of the wiring harness itself can cause the internal adjusting components of the properly adjusted wiring harness fixing device to shift or loosen. This weakens the clamping force of the clamping mechanism on the wiring harness, causes the clamping position to shift, and results in the wiring harness becoming loose and wobbly, making it impossible for the wiring harness to maintain a stable installation state during vehicle operation. This reduces the reliability of the wiring harness fixing, affects the stable operation of the automotive electrical system, and may even cause the wiring harness sheath to break due to friction and wear between the loosened wiring harness and surrounding metal parts, leading to short circuit faults and seriously affecting the driving safety of the vehicle. Therefore, it is necessary to improve the stability of the wiring harness clamping and the reliability of the automotive electrical system. Attached Figure Description

[0021] Please see Figures 1-5A car wiring harness fixing device includes a clip sleeve 1, an adapter block 2 fixedly disposed on the outside of the clip sleeve 1, a control sleeve 3 rotatably disposed on the outside of the clip sleeve 1, a limiting sleeve 4 disposed on the outside of the clip sleeve 1, a sliding sleeve 5 disposed on the outside of the clip sleeve 1, a support rod 6 fixedly connected to one side of the limiting sleeve 4, a rotating plate 7 rotatably disposed on the outside of the clip sleeve 1, a guide block 8 fixedly connected to one side of the rotating plate 7, a guide spring 9 connected to one side of the guide block 8, the other end of the guide spring 9 connected to the adapter block 2, a rotating hole 10 formed on the rotating plate 7, a cooperating seat 11 fixedly disposed on one side of the control sleeve 3, a cooperating rod 12 slidably disposed in the cooperating seat 11, and a clip... The sleeve 1 has a pairing groove 13 inclinedly opened, and a pairing plate 14 is slidably arranged in the pairing groove 13. Multiple cooperating grooves 15 are opened on the outside of the buckle sleeve 1. One end of the cooperating rod 12 is fixedly connected to the cooperating plate 16, and the other end of the cooperating rod 12 is inserted into the cooperating groove 15. A pairing block 17 is fixedly arranged on one side of the pairing plate 14. A matching spring 18 is connected to one side of the pairing block 17.

A movable groove 21 is opened on one side of the movable sleeve 20. A movable block 22 is slidably arranged in the movable groove 21. The movable block 22 is fixedly connected to one side of the pairing block 17.

[0022] In this embodiment, when it is necessary to connect and fix the wire harness, firstly, the rotary plate 7 is rotated forward. Then, the rotary plate 7 will drive the guide block 8 on one side to rotate forward. Then, the guide block 8 will drive the guide rod 25 on one side to rotate forward along the guide hole 26. The guide block 8 will cooperate with the adapter block 2 to squeeze the guide spring 9. At the same time, the rotary plate 7 will drive the rotary hole 10 to rotate forward. When the guide spring 9 is squeezed to the limit, the rotary hole 10 will just rotate to a position concentric with the support rod 6. Then, the limiting sleeve 4 is pushed. The limiting sleeve 4 will drive the inner sliding block 33 to slide along the sliding groove 32. The limiting sleeve 4 will also drive the support rod 6 on one side to gradually slide into the rotary hole 10. At the same time, the limiting sleeve 4 will cooperate with the rotary plate 7 to support the support rod 25. The spring 27 sleeved on the outer side of rod 6 is compressed, causing the inner wall of the limiting sleeve 4 to gradually no longer limit the outer wall of the cooperating plate 16. Then, the control sleeve 3 is rotated in the forward direction. The control sleeve 3 drives the cooperating rod 12, the cooperating plate 16, and the cooperating spring 31 to rotate in the forward direction through the cooperating seat 11 on one side. Then, the inner wall of the cooperating groove 15 compresses one end of the cooperating rod 12. Since the inner wall of the cooperating groove 15 and one end of the cooperating rod 12 are both designed with rounded corners, one end of the cooperating rod 12 will slide out of the cooperating groove 15. The cooperating rod 12 will drive the other end of the cooperating plate 16 to move outward, and the cooperating plate 16 will drive the cooperating spring 31 to stretch outward. At the same time, since the inner wall of the control sleeve 3 and the outer wall of the sliding sleeve 5 are connected by threads, and the two sliding... The sleeves 5 are arranged opposite each other, and the threads at both ends of the inner wall of the control sleeve 3 are symmetrically arranged. Simultaneously, the sliding block 23 and the sliding groove 24 cooperate to limit the rotation of the sliding sleeves 5. Then, the two sliding sleeves 5 will slide synchronously towards the center, and the sliding sleeves 5 will drive the sliding block 23 to slide along the sliding groove 24. Then, the sliding block 23 will drive the inner moving sleeve 20 to slide towards the center. Then, the moving sleeve 20, through the cooperation of the moving groove 21 and the moving block 22, will drive the mating block 17 to move towards the center. The mating block 17 will also drive the guide rod 28, the guide groove 29, the equipped spring 18, and the tensioning plate 19 to move towards the center. Simultaneously, the mating block 17 will drive the mating plate 14 on the other side to slide along the inclined mating groove 13. The rear pairing plate 14 will drive the pairing block 17 on one side to spread outward, so that the pairing block 17 drives the moving block 22 on one side to slide along the moving groove 21. The pairing block 17 will also drive the transmission rod 28, the equipped spring 18, the transmission groove 29 and the tensioning plate 19 to spread outward, so that the tensioning plate 19 and other components spread to the outermost side. At the same time, the two sliding sleeves 5 move to the position where the distance between them is the closest. At this time, the rotation control sleeve 3 is stopped, and then one of the wire bundles is inserted into the buckle sleeve 1. Then, the wire bundle is made to pass out from the other end of the buckle sleeve 1 and connect to one end of the other wire bundle. After the two wire bundles are connected, the original wire bundle is pulled back so that the connection point of the two wire bundles enters the middle position inside the buckle sleeve 1.

[0023] Please see Figures 1-5As a further implementation of the overall device: a sliding block 23 is fixedly provided on the inner side of the sliding sleeve 5, and the inner wall of the sliding sleeve 5 is fixedly connected to the outer wall of the moving sleeve 20 through the sliding block 23. A sliding groove 24 is provided on the side wall of the buckle sleeve 1, and the sliding block 23 slides in the sliding groove 24.

[0024] A guide rod 25 is connected to one side of the guide block 8, and a guide spring 9 is movably sleeved on the outside of the guide rod 25. A guide hole 26 is opened in the adapter block 2, and one end of the guide rod 25 slides into the guide hole 26.

[0025] A spring 27 is movably sleeved on the outside of the support rod 6. One end of the spring 27 is connected to the limiting sleeve 4, and the other end of the spring 27 abuts against one side of the rotary plate 7.

[0026] A guide rod 28 is connected to one side of the tensioning plate 19, and a guide groove 29 is opened in the mating block 17. One end of the guide rod 28 is slidably inserted into the guide groove 29, and multiple rubber strips 30 are fixedly provided on the inner side of the tensioning plate 19.

[0027] The two sliding sleeves 5 are designed to face each other, and the outer wall of the sliding sleeve 5 is connected to the inner wall of the control sleeve 3 by threads. The threads at both ends of the inner wall of the control sleeve 3 are designed to be symmetrical.

[0028] A coordinating spring 31 is movably sleeved on the outside of the coordinating rod 12, and the two ends of the coordinating spring 31 are connected to the coordinating plate 16 and the coordinating seat 11, respectively.

[0029] The outer side of the buckle sleeve 1 is provided with a sliding groove 32, and a sliding block 33 is slidably disposed in the sliding groove 32. The sliding block 33 is fixedly disposed inside the limiting sleeve 4.

[0030] More specifically, when the connection points of the two wire harnesses enter the middle position inside the snap sleeve 1, the control sleeve 3 is rotated in the opposite direction. The control sleeve 3 will drive the cooperating seat 11 on one side to rotate in the opposite direction, and the cooperating seat 11 will drive the cooperating rod 12, the cooperating plate 16, and the cooperating spring 31 to rotate in the opposite direction. Due to the threaded fit between the inner wall of the control sleeve 3 and the outer wall of the sliding sleeve 5, the two sliding sleeves 5 will slide in the opposite direction to both sides simultaneously. Then, the sliding sleeve 5 will drive the sliding block 23 to slide in the opposite direction along the sliding groove 24, so that the sliding block 23 will drive the inner moving sleeve 20 to slide in the opposite direction. Then, the moving sleeve 20 will push the mating block 17 on one side to slide in the opposite direction. At this time, the mating block 17 will drive the transmission rod 28, the transmission groove 29, the equipped spring 18, and the tightening plate 19 on one side to slide in the opposite direction. Furthermore, the mating block 17 will cause one side of the mating plate 14 to slide in the opposite direction along the inclined mating groove 13, causing the mating plate 14 to move the mating block 17 inward. Then, the mating block 17 will move one side of the moving block 22 inward along the moving groove 21. The mating block 17 will also cause the guide rod 28, the spring 18, the guide groove 29, and the tensioning plate 19 to move inward. Then, the rubber strip 30 on the inner wall of the tensioning plate 19 will contact the outer wall of the wire harness. Then, the mating block 17 and other components will continue to move, and the distance between the mating block 17 and the tensioning plate 19 will decrease, causing the guide rod 28 on one side of the tensioning plate 19 to slide into the guide groove 29. The tensioning plate 19 will cooperate with the mating block 17 to compress the spring 18. After the spring 18 is compressed, the two sets of tensioning plates 19 will... The inner walls clamp the outer walls of the two wire harnesses respectively through their inner rubber strips 30. At this time, the rotation of the control sleeve 3 is stopped, and the cooperating seat 11 drives the cooperating rod 12 and other components to rotate to the position corresponding to the cooperating groove 15. Then, the cooperating spring 31 resets and pulls the cooperating plate 16 to slide inward, so that the cooperating plate 16 drives one side of the cooperating rod 12 to insert into the corresponding cooperating groove 15. Then, the limiting sleeve 4 is released, and the support spring 27 resets and pushes the limiting sleeve 4 to drive the inner sliding block 33 to slide and reset along the sliding groove 32. The limiting sleeve 4 will also drive one side of the support rod 6 to slide and reset. When the support spring 27 is fully reset, the support rod 6 no longer passes into the rotating hole 10. Then, the rotating plate 7 is released, and then the guide spring 9 resets and pushes the guide block 8 to rotate and reset in the opposite direction. Block 8 will drive the guide rod 25 on one side to rotate in the opposite direction and reset along the guide hole 26. The guide block 8 will also drive the rotary hole 10 to rotate in the opposite direction and reset to a position not concentric with the support rod 6 via the rotary plate 7. This allows the support rod 6 to support the limiting sleeve 4 on one side of the rotary plate 7. Combined with the sliding block 33 and sliding groove 32 limiting the limiting sleeve 4, the limiting sleeve 4 cannot move. Then, the inner wall of the limiting sleeve 4 again limits the outer wall of the cooperating plate 16, preventing the cooperating plate 16 and the cooperating rod 12 from sliding outwards. The cooperating rod 12, in conjunction with the cooperating groove 15, forms a limit, preventing the cooperating seat 11 and the cooperating rod 12 from sliding outwards. This achieves rotational limitation on the cooperating seat 11 and the control sleeve 3, preventing the control sleeve 3 from rotating unexpectedly, thus ensuring stable clamping of the wire harness.Prevent loosening of wire harness connections.

[0031] In summary, during the use or operation of the overall equipment: when it is necessary to connect and fix the wire harness, firstly, rotate the rotary plate 7 in the forward direction. Then, the rotary plate 7 will drive the guide block 8 on one side to rotate in the forward direction. Then, the guide block 8 will drive the guide rod 25 on one side to rotate in the forward direction along the guide hole 26. The guide block 8 will cooperate with the adapter block 2 to squeeze the guide spring 9, and at the same time, the rotary plate 7 will drive the rotary hole 10 to rotate in the forward direction. When the guide spring 9 is squeezed to the limit, the rotary hole 10 will just rotate to the position concentric with the support rod 6. Then, push the limiting sleeve 4. The limiting sleeve 4 will drive the inner sliding block 33 to slide along the sliding groove 32. The limiting sleeve 4 will also drive the support rod 6 on one side to gradually slide into the rotary hole 10. At the same time, the limiting sleeve 4 will cooperate with the adapter block 2 to squeeze the guide spring 9. The rotating plate 7 compresses the spring 27 sleeved on the outside of the support rod 6, causing the inner wall of the limiting sleeve 4 to gradually no longer limit the outer wall of the cooperating plate 16. Then, the control sleeve 3 rotates forward. The control sleeve 3 drives the cooperating rod 12, the cooperating plate 16, and the cooperating spring 31 to rotate forward through the cooperating seat 11 on one side. Then, the inner wall of the cooperating groove 15 compresses one end of the cooperating rod 12. Since the inner wall of the cooperating groove 15 and one end of the cooperating rod 12 are both designed with rounded corners, one end of the cooperating rod 12 will slide out of the cooperating groove 15. The cooperating rod 12 will drive the other end of the cooperating plate 16 to move outward, and the cooperating plate 16 will drive the cooperating spring 31 to stretch outward. At the same time, since the inner wall of the control sleeve 3 and the outer wall of the sliding sleeve 5 are connected by threads, The two sliding sleeves 5 are arranged opposite each other, and the threads at both ends of the inner wall of the control sleeve 3 are symmetrically arranged. At the same time, the sliding block 23 and the sliding groove 24 cooperate to realize the rotation limit of the sliding sleeve 5. Then, the two sliding sleeves 5 will slide towards the middle in opposite directions at the same time. The sliding sleeve 5 will drive the sliding block 23 to slide along the sliding groove 24. Then, the sliding block 23 will drive the inner moving sleeve 20 to slide towards the middle. Then, the moving sleeve 20 will drive the mating block 17 to move towards the middle through the cooperation of the moving groove 21 and the moving block 22. The mating block 17 will drive the guide rod 28, the guide groove 29, the equipped spring 18 and the tensioning plate 19 to move towards the middle. At the same time, the mating block 17 will drive the mating plate 14 on the other side to slide along the inclined mating groove 13. Then, the pairing plate 14 will drive the pairing block 17 on one side to spread outward, so that the pairing block 17 drives the moving block 22 on one side to slide along the moving groove 21. The pairing block 17 will also drive the transmission rod 28, the equipped spring 18, the transmission groove 29 and the tensioning plate 19 to spread outward, so that the tensioning plate 19 and other components spread to the outermost side. At the same time, the two sliding sleeves 5 move to the position where the distance between them is the closest. At this time, stop rotating the control sleeve 3, and then insert one of the wire bundles into the buckle sleeve 1. Then, let the wire bundle pass out from the other end of the buckle sleeve 1 and connect with one end of the other wire bundle. After the two wire bundles are connected, pull the original wire bundle back so that the connection point of the two wire bundles enters the middle position inside the buckle sleeve 1.

[0032] When the connection points of the two wire harnesses enter the middle position inside the snap sleeve 1, the control sleeve 3 is rotated in the opposite direction. The control sleeve 3 will drive the cooperating seat 11 on one side to rotate in the opposite direction, and the cooperating seat 11 will drive the cooperating rod 12, the cooperating plate 16, and the cooperating spring 31 to rotate in the opposite direction. Due to the threaded fit between the inner wall of the control sleeve 3 and the outer wall of the sliding sleeve 5, the two sliding sleeves 5 will slide in the opposite direction to both sides simultaneously. Then, the sliding sleeve 5 will drive the sliding block 23 to slide along the sliding groove 24 to both sides, so that the sliding block 23 will drive the inner moving sleeve 20 to slide in the opposite direction. Then, the moving sleeve 20 will push the mating block 17 on one side to slide in the opposite direction. At this time, the mating block 17 will drive the transmission rod 28, the transmission groove 29, the equipped spring 18, and the tightening plate 19 on one side to slide in the opposite direction, and the mating block 17 will cause one side of the mating plate 14 to slide in the opposite direction along the inclined mating groove 13, causing the mating plate 14 to move the mating block 17 inward. Then, the mating block 17 will move one side of the moving block 22 inward along the moving groove 21. The mating block 17 will also move the guide rod 28, the spring 18, the guide groove 29, and the tensioning plate 19 inward. Then, the rubber strip 30 on the inner wall of the tensioning plate 19 will contact the outer wall of the wire harness. Then, the mating block 17 and other components will continue to move, and the distance between the mating block 17 and the tensioning plate 19 will decrease, causing the guide rod 28 on one side of the tensioning plate 19 to slide into the guide groove 29. The tensioning plate 19 and the mating block 17 will cooperate to squeeze the spring 18. When the spring 18 is compressed, the inner walls of the two sets of tensioning plates 19 will separate. Do not clamp the outer walls of the two wire harnesses using the inner rubber strip 30. At this point, stop rotating the control sleeve 3 and allow the cooperating seat 11 to rotate the cooperating rod 12 and other components to the position corresponding to the cooperating groove 15. Then, the cooperating spring 31 resets and pulls the cooperating plate 16 to slide inward, so that the cooperating plate 16 drives one side of the cooperating rod 12 to insert into the corresponding cooperating groove 15. Then, release the limiting sleeve 4, and the support spring 27 resets and pushes the limiting sleeve 4 to drive the inner sliding block 33 to slide and reset along the sliding groove 32. The limiting sleeve 4 will also drive one side of the support rod 6 to slide and reset. When the support spring 27 is fully reset, the support rod 6 no longer passes into the rotating hole 10. Then, release the rotating plate 7, and then the guide spring 9 resets and pushes the guide block 8 to rotate and reset in the opposite direction. Then, the guide block 8... This will cause one side of the guide rod 25 to rotate in the opposite direction and reset along the guide hole 26. The guide block 8 will also cause the rotary hole 10 to rotate in the opposite direction and reset to a position not concentric with the support rod 6 via the rotary plate 7. This allows the support rod 6 to support the limiting sleeve 4 to one side of the rotary plate 7. Combined with the sliding block 33 and the sliding groove 32, the limiting sleeve 4 is prevented from moving. Then, the inner wall of the limiting sleeve 4 re-limits the outer wall of the cooperating plate 16, preventing the cooperating plate 16 and the cooperating rod 12 from sliding outwards. The cooperating rod 12, in conjunction with the cooperating groove 15, forms a limit, preventing the cooperating seat 11 and the cooperating rod 12 from sliding outwards. This achieves rotational limitation on the cooperating seat 11 and the control sleeve 3, preventing the control sleeve 3 from rotating unexpectedly, thus ensuring stable clamping of the wire harness.Prevent loosening of wire harness connections.
