[0020] See Figures 1-4 An arc-suppressing segmented insulator load-bearing cable adjustment suspension wire includes a housing 1, an installation groove 2 is opened in the housing 1, and a clamping assembly 3 is installed in the installation groove 2;

[0021] The clamping assembly 3 includes a rotating shaft 31, which is rotatably connected to the mounting groove 2. A gear 32 is fixedly connected to the rotating shaft 31. A slider 33 and a slider 34 are slidably connected in the two mounting grooves 2, and the sliders 33 and 34 are symmetrical about the rotating shaft 31. A rack 35 is fixedly connected to the side wall of both sliders 33 and 34. The two racks 35 are located at the two ends of the gear 32, and both racks 35 mesh with the gear 32. A telescopic rod 36 is fixedly connected between the sliders 33 and 34 and the inner wall of the mounting groove 2. Both slider 1 33 and slider 2 34 are fixedly connected to connecting rods 37. The housing 1 has two slide rails 9. The two connecting rods 37 are slidably installed on the two slide rails 9 respectively. The ends of the two connecting rods 37 are fixedly connected to clamps 38. The rotation of the rotating shaft 1 31 can drive the gear 1 32 to rotate. The gear 1 32 drives the racks 1 35 on both sides to move, so that the two racks 1 35 drive slider 1 33 and slider 2 34 to move towards each other respectively. Slider 1 33 and slider 2 34 drive the two connecting rods 37 to move accordingly. The two connecting rods 37 drive the two clamps 38 to perform clamping and fixing.

[0022] The mounting slot 2 is equipped with a control component 4 for controlling the clamping component 3. Both ends of the housing 1 are fixedly connected to a rotating shaft 3 5. Both rotating shafts 3 5 are rotatably connected to a turntable 6. The turntable 6 is fixedly connected to a rotating rod 7. The rotating rod 7 is equipped with a tensioning component 8.

[0023] Control component 4 includes a second rotating shaft 41, a first support plate 11 fixedly connected in the mounting groove 2, the second rotating shaft 41 rotatably connected to the first support plate 11, a first bevel gear 42 fixedly connected to the second rotating shaft 41, a second bevel gear 43 fixedly connected to the lower end of the first rotating shaft 31, the second bevel gear 43 meshing with the first bevel gear 42, a second gear 44 fixedly connected to the second rotating shaft 41, a second support plate 45 fixedly connected in the mounting groove 2, a spring rod 46 fixedly connected to the lower end of the second support plate 45, a toothed plate 47 fixedly connected to the end of the spring rod 46, the toothed plate 47 meshing with the second gear 44, and the toothed plate 47 slidingly mounted. Installed in the mounting slot 2, the lower end of the toothed plate 47 is fixedly connected to the pull wire 48. The lower end of the housing 1 has a slot, and the pull wire 48 is located in the slot. When it is necessary to control the clamping component 3, the pull wire 48 is pulled, and the pull wire 48 drives the toothed plate 47 to slide downward. During this process, the spring rod 46 changes from the normal state to the stretched state. The toothed plate 47 drives the rotating shaft 41 to rotate through the cooperation with the gear 2 44. The rotating shaft 41 drives the bevel gear 1 42 to rotate. The bevel gear 1 42 replaces the rotation of the bevel gear 2 43, thereby causing the bevel gear 2 43 to drive the rotating shaft 1 31 to rotate, thus realizing the control of the clamping component 3.

[0024] The tensioning assembly 8 includes a slide plate 81, which is slidably installed inside the rotating rod 7. A locking block 83 is slidably connected to the side wall of the rotating rod 7. The side wall of the slide plate 81 has multiple sets of locking slots 82, and the locking slots 82 match the locking blocks 83. A pressure plate 84 is fixedly connected to the locking block 83. A drop wire 85 is fixedly connected to the lower end of each of the two slide plates 81. A mounting plate 86 is fixedly connected to the lower end of each of the two drop wires 85. When the slide plate 81 is pulled down, the slide plate 81 drives the mounting plate 86 to move downward through the drop wires 85. When it moves to the appropriate position, it pushes the pressure plate 84. The pressure plate 84 drives the locking block 83 to move inward to the inside of the rotating rod 7, so that the locking block 83 engages with the locking slot 82, thereby fixing the slide plate 81.

[0025] A clamping block 10 is slidably connected to the mounting plate 86, which can be used to further fix the insulator.

[0026] A pull ring 12 is fixedly connected to one end of the pull cable 48 located on the outside of the housing 1. The pull ring 12 facilitates the control and adjustment of the pull cable 48.

[0027] Anti-slip pads 13 are fixedly installed on both clamps 38. The anti-slip pads 13 can increase the friction with the wires and prevent them from falling off.

[0028] In this invention, firstly, the pull wire 48 is pulled, causing the toothed plate 47 to slide downwards. During this process, the spring rod 46 changes from its normal state to its stretched state. The toothed plate 47, through its cooperation with the gear 2 44, drives the rotating shaft 2 41 to rotate. The rotating shaft 2 41 drives the bevel gear 1 42 to rotate, and the bevel gear 1 42 replaces the rotation of the bevel gear 2 43. This causes the bevel gear 2 43 to drive the rotating shaft 1 31 to rotate. The rotation of the rotating shaft 1 31 can drive the rotation of the gear 1 32. The gear 1 32 drives the racks 1 35 on both sides to move, thereby causing the two teeth... The first strip 35 drives the first slider 33 and the second slider 34 to move towards each other. The first slider 33 and the second slider 34 drive the two connecting rods 37 to move accordingly. The two connecting rods 37 drive the two clamping plates 38 to clamp and fix them. Then, the slide plate 81 is pulled down. The slide plate 81 drives the mounting plate 86 to move down through the drop wire 85. When it moves to the appropriate position, it pushes the pressure plate 84. The pressure plate 84 drives the locking block 83 to move inward to the rotating rod 7, so that the locking block 83 engages with the locking groove 82, thereby fixing the slide plate 81.
