When the staff needs to disconnect the power, directly press the pressing rod, causing the pressing rod to squeeze the spring to contract. The staff can directly pull out the switch blade with the other hand. Such a setting can facilitate the operation and use of the staff and reduce their cumbersome work.

[0015] 2. For the disconnecting switch valve for the distribution network line pole, through the settings of the positioning disk, fixing bolt, rotating disk, line pole body, inserting rod, nut, and sealing pad, when in use, after long-term use of the device, if maintenance and replacement are required, the staff first disconnects the power, rotates the rotating disk, causing the fixing bolt on the rotating disk to separate from the positioning disk, then rotates the nut at the bottom of the device to release the fixing of the inserting rod, and removes the device main body. The sealing pad provided on the nut can effectively protect the thread groove inside the nut, preventing it from being damaged and difficult to remove due to long-term exposure to wind, sun, and rain. Such a setting can facilitate the staff to perform regular maintenance on the device. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the limiting frame 4 is fixedly connected with a spring-back device 6. The bottom of the spring-back device 6 is fixedly connected with a bottom plate 7. The inner wall of the clamping rod 5 is fixedly connected with a spring 8. One end of the spring 8 is fixedly connected with a pressing rod 9. The bottom of the fixed frame 1 is fixedly connected with a positioning plate 10. The bottom of the positioning plate 10 is fixedly connected with a fixing bolt 11. The bottom of the fixing bolt 11 is threadedly connected with a turntable 12. The bottom of the turntable 12 is rotatably connected with a line pole body 13. The bottom of the line pole body 13 is fixedly connected with an inserting rod 14. One end of the inserting rod 14 is threadedly connected with a nut 15. The top edge of the nut 15 is fixedly connected with a sealing gasket 16. Through the settings of the switch blade 2, the connecting frame 3, the limiting frame 4, the clamping rod 5, the spring-back device 6, the bottom plate 7, the spring 8, and the pressing rod 9, when in use, when power needs to be connected, the staff directly rotates the switch blade 2 and inserts it into the connecting frame 3. The switch blade 2 will press the clamping rod 5, causing the clamping rod 5 to rotate downward. At the same time, it will be affected by the force of the spring-back device 6 springing back the bottom plate 7, causing the clamping rod 5 to spring back and be stuck in the card slot of the switch blade 2. When the staff needs to disconnect the power, directly press the pressing rod 9 to squeeze the spring 8 to contract. The staff uses the other hand to directly pull out the switch blade 2. Such a setting can facilitate the operation and use of the staff and reduce their cumbersome work. Through the settings of the positioning plate 10, the fixing bolt 11, the turntable 12, the line pole body 13, the inserting rod 14, the nut 15, and the sealing gasket 16, when in use, after long-term use of the device, maintenance and replacement are required. The staff first disconnects the power, rotates the turntable 12 to separate the fixing bolt 11 on the turntable 12 from the positioning plate 10, then rotates the nut 15 at the bottom of the device to release the fixation of the inserting rod 14 by the nut 15, and removes the device main body. The sealing gasket 16 provided on the nut 15 can effectively protect the thread groove inside the nut 15, preventing it from being damaged due to long-term exposure to wind and sun and being difficult to remove. Such a setting can facilitate the staff to perform regular maintenance on the device.

[0023] A fixing frame 17 is arranged on the side of the inserting rod 14. The bottom of the fixing frame 17 is arranged on the top of the sealing gasket 16. Through the settings of the inserting rod 14, the fixing frame 17, and the sealing gasket 16, when in use, the fixing frame 17 is clamped between the inserting rod 14 and the sealing gasket 16.

[0024] A telescopic rod 18 is arranged inside the spring 8. One end of the telescopic rod 18 is fixedly connected to one end of the pressing rod 9. Through the settings of the spring 8, the telescopic rod 18, and the pressing rod 9, when in use, the telescopic rod 18 inside the spring 8 can prevent the spring 8 from tilting.

[0025] One end of the switch blade 2 is fixedly connected to a handle 19, and an insulating pad 20 is fixedly connected to the outer surface of the handle 19. Through the arrangement of the switch blade 2, the handle 19 and the insulating pad 20, during use, the staff can pull the insulating pad 20 on the handle 19 to pull out the switch blade 2.

[0026] A rectangular groove is formed on the side surface of the nut 15, and a friction plate 21 is fixedly connected to the inner wall of the rectangular groove. Through the arrangement of the nut 15 and the friction plate 21, during use, the friction plate 21 on the nut 15 can facilitate the staff to disassemble it.

[0027] An arc-shaped groove is formed at one end of the switch blade 2, and a wear-resistant pad 22 is fixedly connected to the inner wall of the arc-shaped groove. Through the arrangement of the switch blade 2 and the wear-resistant pad 22, during use, the wear-resistant pad 22 can reduce the damage to the card slot of the switch blade 2 caused by frequent use.

[0028] In the present utility model, the working steps of the device are as follows:

[0029] The first step: When power needs to be connected, the staff directly rotates the switch blade 2 and inserts it into the connection frame 3. The switch blade 2 will press the latch 5, causing the latch 5 to rotate downward. At the same time, it will be affected by the force of the spring-back device 6 to spring back the bottom plate 7, causing the latch 5 to spring back and latch in the card slot of the switch blade 2. When the staff needs to disconnect the power, directly press the pressing rod 9, causing the pressing rod 9 to squeeze the spring 8 to contract. The staff can use the other hand to pull the insulating pad 20 on the handle 19 to pull out the switch blade 2;

[0030] The second step: After long-term use of the device, maintenance and replacement are required. The staff first disconnects the power, rotates the turntable 12 to separate the turntable 12 from the fixing bolt 11 on the positioning plate 10, and then rotates the nut 15 at the bottom of the device to release the fixation of the insertion rod 14 by the nut 15, and removes the device main body. The sealing pad 16 provided on the nut 15 can effectively protect the thread groove inside the nut 15 to prevent it from being damaged and difficult to remove due to long-term exposure to wind and sun.
