This flexible assembly improves ease of use. The structure is simple, the assembly operation is simple and convenient, and it is easy to flexibly adapt to the size adjustment requirements, thus expanding the applicability of the post insulator.

One end of each threaded rod 13 is fixedly connected to a first bevel gear 12. A second bevel gear 11 is rotatably connected to one side of the interior of the movable slot 8. The outer surfaces of the two first bevel gears 12 mesh with the outer surfaces of the second bevel gear 11 respectively. A first knob 7 is fixedly connected to one side of the second bevel gear 11 through one side of the mounting bracket 5.

[0035] In this embodiment, before installing the insulator body 1, the pre-installation plate 6 can be fixed first, and then the insulator body 1 can be installed on the pre-installation plate 6. When the insulator body 1 fails and needs to be replaced, the first knob 7 on the side of the mounting bracket 5 can be turned to drive the second bevel gear 11 to rotate. The rotating second bevel gear 11 can drive the first bevel gear 12 to rotate. At this time, the threaded rod 13 fixedly connected to it can rotate accordingly, and after rotation, it drives the locking rod 9 threadedly connected to it to move, causing the locking rod 9 to slide into the movable groove 8 and its end to be pulled out from the holes 14 on both sides of the locking bracket 4. Then the insulator body 1 can be removed from the mounting bracket 5. When installing a new insulator body 1, the above operation can be repeated in reverse. This method makes the disassembly of the insulator body 1 more convenient when it needs to be replaced. It ensures the stability of the installation and makes the installation and replacement work more convenient, improving the efficiency of the disassembly and assembly of the insulator body 1.

[0036] Example 2, as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a first clamp 2 is fixedly connected to the upper end of the insulator body 1. A second clamp 3 is installed above the first clamp 2. A first connecting plate 18 is fixedly connected to both sides of the first clamp 2. A second connecting plate 17 is fixedly connected to both sides of the second clamp 3. A connecting rod 21 is slidably connected to the middle of each of the two second connecting plates 17. A pressing plate 23 is fixedly connected to the upper end of each of the two connecting rods 21. A rotating ring 24 is rotatably connected to the lower end of each of the two pressing plates 23. A spring 25 is fixedly connected to the lower end of each of the two rotating rings 24. The lower ends of the two springs 25 are respectively connected to the two second connecting plates 28. The upper end of the first connecting plate 17 is fixedly connected. The middle of the two first connecting plates 18 is provided with mounting grooves 22. The lower ends of the two connecting rods 21 are fixedly connected with limit brackets 26. The lower end of the two first connecting plates 18 is fixedly connected with a slide rod 20 on one side. The two sides of the outer surface of the two slide rods 20 are slidably connected with fixing plates 19. The other side of the lower end of the two first connecting plates 18 is rotatably connected with a double-acting screw 15. The outer surface of the two double-acting screws 15 is threaded to one end of the four fixing plates 19 respectively. The two double-acting screws 15 are fixedly connected with a second knob 16 on one end.

[0037] In this embodiment, when connecting the No. 1 clamp 2 and the No. 2 clamp 3, the No. 2 connecting plates 17 on both sides of the No. 2 clamp 3 and the No. 1 connecting plates 18 on both sides of the No. 1 clamp 2 can be aligned with each other. Then, the limiting bracket 26 under the No. 2 connecting plate 17 will enter the mounting groove 22 in the middle of the No. 1 connecting plate 18. Then, the pressing plate 23 is pressed down to make the limiting bracket 26 completely pass through the mounting groove 22. Then, the limiting bracket 26 is rotated 90 degrees so that both ends of the limiting bracket 26 are locked into the No. 1 connecting plate. Below 18, the double-acting screw 15 is rotated by turning the second knob 16. The rotating double-acting screw 15 can cause the fixing plates 19 to come together and clamp and fix the two sides of the limiting frame 26. At this time, the connection between the first clamp 2 and the second clamp 3 can be completed. This method makes the connection between the first clamp 2 and the second clamp 3 simpler and more convenient, improves the connection and fixing efficiency of the first clamp 2 and the second clamp 3, and reduces the difficulty of working at height.

[0038] Working Principle: Before installing the insulator body 1, its pre-installation plate 6 can be fixed first. Then, the insulator body 1 can be installed on the pre-installation plate 6. When the insulator body 1 needs to be replaced due to failure, the first knob 7 on the side of the mounting bracket 5 can be turned to rotate the second bevel gear 11. The rotating second bevel gear 11 can drive the first bevel gear 12 to rotate. At this time, the threaded rod 13 fixedly connected to it can rotate accordingly. After rotation, it drives the locking rod 9 threadedly connected to it to move, causing the locking rod 9 to slide into the movable groove 8 and its end to be pulled out from the holes 14 on both sides of the locking bracket 4. Then, the insulator body 1 can be removed from the mounting bracket 5. When installing a new insulator body 1, the above operation can be repeated in reverse. This method makes the disassembly of the insulator body 1 more convenient when it needs to be replaced, ensuring the stability of the installation and making the installation and replacement work more convenient. To improve the efficiency of insulator body 1 assembly and disassembly, when connecting clamp 2 and clamp 3, the No. 2 connecting plates 17 on both sides of clamp 3 and the No. 1 connecting plates 18 on both sides of clamp 2 can be aligned. Then, the limiting bracket 26 below the No. 2 connecting plate 17 will enter the mounting groove 22 in the middle of the No. 1 connecting plate 18. Next, the pressing plate 23 is pressed down to ensure the limiting bracket 26 completely passes through the mounting groove 22. Then, the limiting bracket 26 is rotated 90 degrees so that both ends of the limiting bracket 26 are locked together. Below the connecting plate 18, the double-acting screw 15 is rotated by turning the second knob 16. The rotating double-acting screw 15 can cause the fixing plates 19 to come together and clamp and fix the two sides of the limiting frame 26. At this time, the connection work of the first wire clamp 2 and the second wire clamp 3 can be completed. This method makes the connection work of the first wire clamp 2 and the second wire clamp 3 simpler and more convenient, improves the connection and fixing efficiency of the first wire clamp 2 and the second wire clamp 3, and reduces the difficulty of working at height.
