First, squeeze the rotating plate 10 into the receiving groove 11 of the core shaft body 2, and insert the core shaft body 2 into the middle of the connecting seat 1, so that the protrusion in the middle of the core shaft body 2 is flush with the bottom of the connecting seat 1, and then rotate the core shaft body 2 so that the protrusion 15 on the rotating plate 10 can be aligned with the groove 8, so that the spring rod 12 can push the rotating plate 10, so that the protrusion 15 can be inserted into the groove 8 and engage under the action of the triangular block, so that the core shaft body 2 is quickly fixed in the middle of the connecting seat 1 and cannot be moved, so as to quickly install the core shaft, improve installation efficiency, and reduce installation time.

[0026] Reference Figure 2 , 4and 5. A disassembly assembly is installed in the middle of the connecting seat 1, and the disassembly assembly includes a gear ring 3, which is rotatably connected to the middle of the connecting seat 1. An annular groove is provided on the outer periphery of the connecting seat 1. The thickness of the gear ring 3 is equal to the thickness of the annular groove. A gear 5 is rotatably connected to the middle of the connecting seat 1, and the gear ring 3 is meshed with the gear ring 3. A threaded rod 6 is fixedly connected to the bottom of the gear 5. A threaded block 7 is threadedly connected to the outer periphery of the threaded rod 6. The threaded block 7 is in contact with the protrusion 15. An arc edge is provided on the outer side of the protrusion 15, and a notch is provided on the inner side of the threaded block 7. Rotate the gear ring 3 to move the gear 5, and drive the threaded rod 6 to rotate through the gear 5, so that the threaded block 7 can move up and down under the action of the threaded rod 6, so that the notch of the threaded block 7 can squeeze the arc edge of the protrusion 15, so that the protrusion 15 can be squeezed out from the middle of the groove 8, and then the core shaft body 2 can be quickly removed from the middle of the connecting seat 1, thereby improving the inspection and maintenance efficiency. At the same time, under the action of the equal thickness of the gear ring 3 and the annular groove, the gear ring 3 and the outer edge of the connecting seat 1 can be tightly fitted, reducing scratches during use.

[0027] Reference Figure 1 , 2 6, the inside of the connection seat 1 is fixedly connected with a sealing ring 2 9, the upper and lower sides of the gear ring 3 are fixedly connected with a limiting block 14, the middle part of the connection seat 1 is provided with a limiting groove 13, the limiting block 14 is rotatably connected to the middle part of the limiting groove 13, and the bottom of the connection seat 1 is fixedly connected with a sealing ring 1 4. Under the action of the sealing ring 2 9, the sealing performance between the core shaft body 2 and the inside of the connection seat 1 can be improved, and at the same time, under the action of the sealing ring 1 4, the sealing performance between the subsequent connecting parts is also improved, so as to reduce the external moisture from entering the connection seat 1, affecting the service life of the connection seat 1 and the core shaft body 2, and at the same time, under the action of the limiting groove 13 and the limiting block 14, the external moisture is reduced from entering the interior through the gap between the gear ring 3 and the connection seat 1, further reducing the erosion of the internal structure and improving the service life.

[0028] Working principle: First, squeeze the rotating plate 10 to insert the core shaft body 2 into the middle of the connecting seat 1. Under the push of the spring rod 12, the protrusion 15 on the rotating plate 10 slides to the position of the groove 8, and can be pushed in by the spring rod 12 for engagement, so as to quickly engage the core shaft body 2 in the middle of the connecting seat 1, and then rotate the gear ring 3 to drive the gear 5, so that the threaded rod 6 at the bottom of the gear 5 drives the threaded block 7 to move so as to squeeze the protrusion 15 out of the middle of the groove 8, so as to quickly disassemble or install the core shaft body 2, thereby reducing the time for inspection and maintenance.

[0029] The sealing ring 2 9 and the sealing ring 1 4 can improve the sealing between different connecting parts. At the same time, the sealing of the connecting seat 1 can be further improved under the action of the limiting groove 13 and the limiting block 14, thereby reducing the moisture erosion inside the connecting seat 1.
