The tops of the threaded rods 6 are fixedly connected to the bottoms of the fixed rings 5. The rotating rods 12 are located inside the lower circular ring 11 and are rotatably connected to the lower circular ring 11. The tops of the rotating rods 12 are fixedly connected to the bottoms of the threaded tubes 9. The inner walls of the threaded tubes 9 are screwed to the outer walls of the threaded rods 6. The tops of the threaded rods 6 are fixedly connected to the bottoms of the upper fixed rings 5. The toothed ring 14 is located inside the lower fixed ring 5 and is rotatably connected to the lower fixed ring 5. Tooth grooves 15 are opened on the outer walls of the rotating rods 12, and the toothed ring 14 is engaged with the tooth grooves 15. A hexagonal block 13 is fixed to the bottom of the rotating rod 12. A fixing mechanism 26 is provided inside the circular ring 11 to fixedly connect the tops and bottoms of the two circular rings 11 and the wire mesh 2. Then rotate the hexagonal block 13. The hexagonal block 13 drives the rotating rod 12 to rotate. The rotating rod 12 drives the toothed ring 14 to rotate through the tooth grooves 15. The toothed ring 14 drives the other rotating rods 12 to rotate. The rotating rods 12 drive the threaded tubes 9 to rotate. In this way, the two circular rings 11 can be separated, and the wire mesh 2 can be straightened, preventing the wire mesh 2 from being flattened during installation or transportation, resulting in deformation of the wire mesh 2. The deformed wire mesh 2 will squeeze the inner core 4, causing deformation and damage to the inner core 4.

[0023] Further, the fixing mechanism 26 includes a plurality of pushing blocks 20, a plurality of pressing springs 22 and a plurality of pins 24. A plurality of receiving holes 23 are formed inside the ring 11. The pressing springs 22 are fixed inside the receiving holes 23.

The pin 24 is inserted into the wire mesh 2. In this way, the wire mesh 2 can be fixedly connected to the ring 11. At the same time, the plug rod 19 is inserted into the jack 10 to fix the swivel ring 7. In this way, the fixing is simple and convenient.

[0024] During work, after the wire mesh 2 is inserted into the annular slot 8, the swivel ring 7 is rotated. The swivel ring 7 presses the pushing block 20. The pushing block 20 drives the pin 24 to move. The pin 24 is inserted into the wire mesh 2. In this way, the wire mesh 2 can be fixedly connected to the ring 11. At the same time, the plug rod 19 is inserted into the jack 10 to fix the swivel ring 7. Then the hexagonal block 13 is rotated. The hexagonal block 13 drives the rotating rod 12 to rotate. The rotating rod 12 drives the toothed ring 14 to rotate through the tooth groove 15. The toothed ring 14 drives other rotating rods 12 to rotate. The rotating rod 12 drives the threaded tube 9 to rotate. In this way, the two rings 11 can be separated. In this way, the wire mesh 2 can be straightened to prevent the wire mesh 2 from being flattened during installation or transportation, resulting in deformation of the wire mesh 2. The deformation of the wire mesh 2 will squeeze the inner core 4, resulting in deformation and damage of the inner core 4.
