[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses an elastic component and a driving component in conjunction with an adjustable fixing component to clamp the insulating operating rod, making the connection between the joint and the insulating rod convenient and applicable to insulating rods of various diameters.

[0019] 2. The present invention uses a clamping arc block to bite and fix the insulating rod, and uses the knurling of the pliers to adjust the position of the threaded rod, so that the operator can quickly fix the insulating rod when wearing insulating gloves, thereby facilitating the assembly of the ends of insulating rods of different specifications and sizes, and quickly fixing wires of different wire diameters, thereby improving the work efficiency of the operator during live operations.

[0020] 3. In the present invention, when the operator needs to separate the end of the insulating rod from the joint body, the operator rotates the threaded rod again so that the end of the threaded rod no longer presses against the clamping arc block. At this time, the elastic rope is no longer expanded under force, and the elastic rope contracts, driving the guide rod to slide inside the joint body, so that the clamping arc block is away from the end of the insulating rod, so as to facilitate the disassembly of the insulating rod.

[0021] 4. In the present invention, when the tightness of the elastic rope decreases, the motor can be driven by the PLC controller to drive the second gear to rotate. By utilizing the mutual engagement characteristic of the second gear and the first gear, the second gear drives the second ring to rotate through the first gear. When the second ring rotates, it drives the elastic rope to reel in, thereby tightening the elastic rope, making it easier for the elastic rope to pull the clamping arc block outward through the guide rod.

[0022] 5. The diameter of the first gear of the present invention is larger than that of the second gear. With this structure, when the motor drives the second gear to rotate, the range of rotation of the first gear driven by the second gear is smaller, thereby facilitating the first gear to accurately adjust the tension of the elastic rope.

[0023] 6. The drive assembly of the present invention is provided with multiple levels. When any component of the drive assembly is damaged, it can be removed and replaced more conveniently, avoiding the situation of removing multiple components in order to replace one component.

[0024] 7. The present invention widens the chuck of the locking pliers. When in use, the staff drives the eccentric wheel to rotate by rotating the knob. When the eccentric wheel rotates at different angles, the distance between the eccentric wheel rotation point and the slider is different. Then, the slider drives the support rod to move, causing the support rod to move the second clamp handle, thereby achieving the effect of adjusting the size of the locking pliers opening by using the lever principle.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figures 1-11 As shown, this embodiment is suitable for insulating rods of various wire diameters, including a connector body 1, a fixing component 2, an insulating rod 6 and a hook 7, one end of the insulating rod 6 is detachably connected to the hook 7, and a slot 11 is longitudinally opened in the connector body 1; the fixing component 2 is arranged inside the slot 11, and the other end of the insulating rod 6 is detachably connected to the connector body 1 through the fixing component 2, and also includes an elastic component 3 and a driving component 4, one end of the elastic component 3 is connected to the fixing component 2, and the other end of the elastic component 3 is connected to the driving component 4; the driving component 4 adjusts the range of motion of the fixing component 2 through the elastic component 3.

[0040] The present invention uses the elastic component 3 and the driving component 4 in conjunction with the adjustable fixing component 2 to clamp the insulating rod 6, so that the connection between the joint body 1 and the insulating rod 6 is convenient and can be applied to insulating rods 6 of various diameters.

[0041] Furthermore, a pair of side ears 12 are fixed to an outer side wall of the connector body 1 , and a through hole 13 is formed in the side ears 12 in a transverse direction.

[0042] Furthermore, the fixing components 2 are arranged in pairs on both sides of the joint body 1, and one fixing component 2 includes a clamping arc block 21, a guide rod 22, an internal threaded tube 23 and a threaded rod 24, the internal threaded tube 23 passes through the side wall of the joint body 1 and is fixed to the joint body 1; the outer periphery of the threaded rod 24 is threadedly connected to the inner wall of the internal threaded tube 23; the two guide rods 22 are symmetrically arranged on both sides of the threaded rod 24, one end of the guide rod 22 passes through the side wall of the joint body 1 and is slidingly connected to the joint body 1, and the other end of the guide rod 22 is located outside the joint body 1 and is fixed to the elastic component 3; one end of the clamping arc block 21 is fixed to the guide rod 22 and abuts against the threaded rod 24.

[0043] The insulating rod 6 is fixed by the clamping arc block 21, and the position of the threaded rod 24 is adjusted by the knurling of the pliers, so that the operator can quickly fix the insulating rod 6 even when wearing insulating gloves. This makes it easier to assemble the ends of the insulating rod 6 of different specifications and sizes, and quickly fix wires of different wire diameters, thereby improving the work efficiency of the operator during live operations. The opposite ends of the two clamping arc blocks 21 are fixed with rubber pads 211, which can improve the tightness of the connection between the clamping arc block 21 and the insulating rod 6.

[0044] Furthermore, the elastic component 3 includes an elastic rope 32, two first rings 31 are respectively fixed to a guide rod 22; the second ring 33 is fixed to the driving component 4; one end of the two elastic ropes 32 is respectively fixed to the outer wall of a first ring 31, and the other end of the two elastic ropes 32 is fixed to the outer wall of the second ring 33.

[0045] The elastic component 3 helps to reset the clamping arc block 21. When the operator needs to separate the end of the insulating rod 6 from the joint body 1, the operator rotates the threaded rod 24 again so that the end of the threaded rod 24 no longer presses against the clamping arc block 21. At this time, the elastic rope 32 is no longer under force to expand, and the elastic rope 32 contracts, driving the guide rod 22 to slide inside the joint body 1, so that the clamping arc block 21 is away from the end of the insulating rod 6, so as to facilitate the disassembly of the insulating rod 6.

[0046] Furthermore, the drive assembly 4 includes a first gear 44 and a control device. One end of the fixed shaft 46 passes through the first gear 44 and the second ring 33 in sequence and is fixed to the outer wall of the joint body 1. The first gear 44 and the second ring 33 are both rotatably connected to the outer wall of the fixed shaft 46, and the first gear 44 is fixed to the second ring 33; the control device is used to control the rotation of the first gear 44.

[0047] The driving assembly 4 is provided with multiple stages. When any component of the driving assembly 4 is damaged, it can be removed and replaced more conveniently, avoiding the situation of removing multiple components in order to replace one component.

[0048] Furthermore, the control device includes an installation box 41, a motor 42, a PLC controller 43 and a second gear 45. The installation box 41 is arranged below the fixed shaft 46, and the installation box 41 is fixed to the outer wall of the joint body 1; the motor 42 and the PLC controller 43 are fixed inside the installation box 41, and the PLC controller 43 is electrically connected to the motor 42; the output shaft of the motor 42 extends to the outside of the installation box 41 and is fixed to the second gear 45, and the second gear 45 is engaged with the first gear 44.

[0049] When the tightness of the elastic rope 32 decreases, the motor 42 can be driven by the PLC controller 43, so that the motor 42 drives the second gear 45 to rotate. By utilizing the mutual engagement between the second gear 45 and the first gear 44, the second gear 45 drives the second ring 33 to rotate through the first gear 44. When the second ring 33 rotates, it drives the elastic rope 32 to reel in, so as to tighten the elastic rope 32, so that the elastic rope 32 can pull the clamping arc block 21 outward through the guide rod 22.

[0050] Furthermore, the diameter of the first gear 44 is greater than the diameter of the second gear 45 .

[0051] Furthermore, a heat dissipation window 47 is provided on the outer wall of the installation box 41 .

[0052] Furthermore, it also includes locking pliers 5, which are arranged between the two side ears 12, and one end of the fixing bolt 56 passes through a through hole 13 and then penetrates the locking pliers 5 and extends to the outside of the other through hole 13, and the fixing bolt 56 is fixed to the locking pliers 5 and the side ears 12; the locking pliers 5 include a first handle 51, a second handle 52, an adjustment assembly 53 and a support rod 54, the adjustment assembly 53 is arranged inside the first handle 51, one end of the support rod 54 is fixed to the adjustment assembly 53, and the other end of the support rod 54 is fixed to the second handle 52; the adjustment assembly 53 is used to adjust the size of the opening of the locking pliers 5.

[0053] The connector body 1 is assembled with the top of the insulating rod 6 by using the through hole 13 opened on the side wall of the side ear 12. The hanging connector of the insulating rod 6 is modified. When in use, the wire is fixed by biting the pliers 5 to ensure a reliable connection. A safety rod 55 is fixed inside the second pliers handle 52.

[0054] Furthermore, the adjustment assembly 53 includes an eccentric wheel 531, a mounting plate 532, a top block 534, a spring 535, a slider 536 and a knob 537. The knob 537 is arranged on the outer wall of the first clamp handle 51. The central axis 5371 of the knob 537 passes through the first clamp handle 51 and is fixed to the eccentric wheel 531. The mounting plate 532 is fixed to the inner wall of the first clamp handle 51. A mounting groove 533 is fixed to the bottom of the inner periphery of the mounting plate 532. The spring 535 and the top block 534 are fixed to the mounting groove 533 from the inside to the outside. One end of the eccentric wheel 531 extends to the inside of the mounting plate 532. The surface of the eccentric wheel 531 inside the mounting plate 532 is provided with a groove matching the top block 534. The spring 535 always provides thrust to the top block 534. The top of the other end of the eccentric wheel 531 is slidably connected to the bottom of the slider 536, and the top of the slider 536 is fixed to one end of the support rod 54.

[0055] The clamp head of the locking pliers 5 is widened. When in use, the staff drives the eccentric wheel 531 to rotate by rotating the knob 537. When the eccentric wheel 531 rotates at different angles, the distance between the rotation point of the eccentric wheel 531 and the slider 536 is different. The eccentric wheel 531 provides different degrees of displacement to the slider 536, and then drives the support rod 54 to move through the slider 536, and moves the second clamp handle 52 through the support rod 54. Since the distance between the rotation point of the eccentric wheel 531 and the outer periphery of the eccentric wheel 531 is different, a space is only provided below the rotation point of the eccentric wheel 531. The top block 534 and spring 535 are provided to prevent the eccentric wheel 531 from colliding with the mounting slot 533 during rotation. The spring 535 always provides thrust to the top block 534, so that the top block 534 always presses against the eccentric wheel 531. Due to the pressure of the top block 534, the eccentric wheel 531 can only rotate in sections, making the jaw adjustment more precise. At the same time, due to the pressure of the top block 534, when the knob 537 is not rotated, the top block 534 has a fixed effect on the eccentric wheel 531, which can prevent the jaw size from changing arbitrarily. A scale dial 538 is fixed below the knob 537. When the knob 537 is rotated, the scale dial 538 can be used to intuitively observe the angle of rotation of the knob 537.

[0056] The method of use of the present invention is:

[0057] Insert the end of the insulating rod 6 into the slot 11;

[0058] Using the drive assembly 4 to adjust the elastic force of the elastic cord 32;

[0059] When the tightness of the elastic rope 32 decreases, the motor 42 can be driven by the PLC controller 43, so that the motor 42 drives the second gear 45 to rotate. By utilizing the mutual engagement between the second gear 45 and the first gear 44, the second gear 45 drives the second ring 33 to rotate through the first gear 44. When the second ring 33 rotates, it drives the elastic rope 32 to reel in, so as to tighten the elastic rope 32, so that the elastic rope 32 can pull the clamping arc block 21 outward through the guide rod 22.

[0060] Rotate the threaded rod 24 so that the threaded rod 24 pushes the clamping arc block 21 to clamp the end of the insulating rod 6, thus completing the fixing of the insulating rod 6;

[0061] The clamping arc block 21 is simultaneously subjected to the inward thrust of the threaded rod 24 and the outward pulling force of the guide rod 22. Under the joint action of the threaded rod 24 and the guide rod 22, the clamping arc block 21 is always tightly fitted with the threaded rod 24, and the position of the clamping arc block 21 can be more accurately controlled.

[0062] Install the locking pliers 5 and use the locking pliers 5 to clamp the wire to secure the entire device.

[0063] The eccentric wheel 531 is driven to rotate by rotating the knob 537. When the rotation angle of the eccentric wheel 531 is different, the distance between the rotation point of the eccentric wheel 531 and the slider 536 is different, and then the slider 536 drives the support rod 54 to move, so that the support rod 54 moves the second clamp handle 52, thereby using the lever principle to adjust the opening size of the pliers 5.

[0064] When removing the insulating rod 6, the threaded rod 24 is rotated outward. At this time, the elastic rope 32 can pull the clamping arc block 21 outward through the guide rod 22, so that the clamping arc block 21 is separated from the insulating rod 6; the fixing bolt 56 is unscrewed to separate the joint body 1 and the pliers 5.

[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
