Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] Refer to Figure 1 、 Figure 2 and Figure 3, An embodiment provided by the present utility model: An insulator with adjustable distance, including a mounting plate 1. Grooves 4 are opened on both sides of the front end of the mounting plate 1. Push blocks 3 are slidably connected inside the two grooves 4. Cavities 17 are opened inside the two push blocks 3. Slots 6 are opened on both the top and bottom sides of the front ends of the two push blocks 3. Fixing rods 8 penetrate through the two cavities 17. On both sides of one end of the two fixing rods 8, bumps 15 are fixedly connected. Fixing grooves 16 are opened at the front ends of the multiple bumps 15. Installation grooves 12 are opened on both sides of the front end of the inner side walls of the two cavities 17. Fixing blocks 14 are slidably connected inside the multiple installation grooves 12.

One end of each of the multiple spring two 13 is fixedly connected to the front end of the inner side wall of the installation groove 12, and the other end of each of the multiple spring two 13 is fixedly connected to the end of the fixing block 14 close to the pull rod 5. Inside the two grooves 4, sliding rods 9 are fixedly connected. The outer sides of the middle parts of the two sliding rods 9 penetrate through the push blocks 3;

[0041] Specifically, after inserting the two fixing rods 8 into the cavities 17, rotate the fixing rods 8 by 90 degrees to move the bumps 15 to the rear side of the fixing blocks 14. At the same time, push the fixing blocks 14 into the fixing grooves 16 at the front ends of the bumps 15 through the spring two 13, so as to fix the fixing rods 8.

[0042] Refer to 2 and Figure 4 , On the top of the two push blocks 3, an adjusting mechanism 2 is arranged. The adjusting mechanism 2 includes two spring one 202. Installation bins 206 are opened on the rear sides of the tops of the two push blocks 3. One end of each of the two spring one 202 is fixedly connected to the inner bottom wall of the installation bin 206. The other end of each of the two spring one 202 is fixedly connected with a limiting block 201. Multiple uniformly distributed limiting grooves 205 are opened on the inner top walls of the two grooves 4. One end of each of the two limiting blocks 201 away from the spring one 202 is slidably connected inside the limiting grooves 205;

[0043] Specifically, the sliding of the push block 3 drives the fixing rod 8 to slide inside the groove 4, so as to adjust the distance between the two fixing rods 8. After the distance between the fixing rods 8 is adjusted, the spring one 202 can push the limiting block 201 into the limiting groove 205 to limit and fix the push block 3.

[0044] Refer to Figure 4 , On both sides of the inner side walls of the two installation bins 206, sliding grooves 203 are opened. Sliding blocks 204 are slidably connected inside the multiple sliding grooves 203. The adjacent sides of the multiple sliding blocks 204 are respectively fixedly connected to both sides of the limiting block 201;

[0045] Specifically, the cooperation between the slider 204 and the chute 203 limits the limiting block 201, thereby preventing the limiting groove 205 from pulling the limiting block 201 to move when the pushing block 3 moves, so that the first spring 202 is deformed.

[0046] Refer to Figure 1 and Figure 5 , at the ends of the two fixing rods 8 away from the pushing block 3, connection lines 11 are fixedly connected, and bells 10 are fixedly connected to the other ends of the two connection lines 11. Porcelain parts 7 are fixedly connected to the outer sides of the two fixing rods 8;

[0047] Specifically, the airflow at high altitude blows the bells 10 on the fixing rods 8 to shake, so that they emit ringing sounds, thereby driving away the birds at the top of the fixing rods 8.

The other ends of the two fixing rings 19 are fixedly connected with side plates 21, and a plurality of uniformly distributed spheres 20 are fixedly connected to the adjacent sides of the two fixing rings 19;

[0049] Specifically, place the mounting plate 1 in front of the top of the support rod, then separate the two fixing rings 19 and sleeved them on the outer side of the support rod. At the same time, pass bolts through the two side plates 21 and tighten them to fix the mounting plate 1.

[0050] Working principle: Place the mounting plate 1 in front of the top of the support rod, then separate the two fixing rings 19 and sleeved them on the outer side of the support rod. At the same time, pass bolts through the two side plates 21 and tighten them to fix the mounting plate 1. Then insert the two fixing rods 8 into the cavity 17 and rotate the fixing rods 8 by 90 degrees so that the convex blocks 15 move to the rear side of the fixing block 14. At the same time, push the fixing block 14 into the fixing groove 16 at the front end of the convex block 15 through the second spring 13 to fix the fixing rods 8. And by sliding the pushing block 3, it drives the fixing rods 8 to slide in the groove 4, so as to adjust the distance between the two fixing rods 8. After the distance between the fixing rods 8 is adjusted, the limiting block 201 can be pushed into the limiting groove 205 through the first spring 202 to limit and fix the pushing block 3; and place the cable in the groove 4 of the porcelain part 7 to support it. At the same time, the airflow at high altitude can blow the bells 10 on the fixing rods 8 to shake, so that they emit ringing sounds to drive away the birds at the top of the fixing rods 8. When it is necessary to disassemble the fixing rods 8, pull the pull rod 5 to make the fixing block withdraw from the fixing groove 16. Then rotate the fixing rods 8 again so that the two convex blocks 15 move to the rear side of the slot 6, and at the same time pull the fixing rods 8 forward so that the convex blocks 15 withdraw from the cavity 17 through the slot 6, so that the staff can replace them.
