[0010] Further, in order to fix the sealing plate on the fixing ring, through holes are opened between the threaded holes. The through holes communicate with the fixing grooves. The through rods match the through holes and the grooves.

[0011] Further, in order to enable the limiting rod to move on the fixing block, holes are symmetrically opened at both ends of the outer surface of the fixing block. The holes communicate with the limiting grooves. The limiting rod passes through the holes and extends outside the fixing block.

[0012] Further, in order to fix the limiting rod in the fixing groove, limiting holes are symmetrically opened at both ends of the inner surface of the fixing groove. The limiting holes match the limiting rods.

The outer surface of the fixing ring 1 is detachably connected with winding columns 4 at equal intervals. One end of the winding column 4 far from the fixing ring 1 is fixedly connected with an arc plate 6. A detachable component is provided between the winding column 4 and the fixing ring 1. The detachable component includes fixing grooves 2 opened on the outer surface of the fixing ring 1 at equal intervals. One end of the winding column 4 close to the fixing ring 1 is welded with a fixing block 3. The fixing block 3 is adapted to the fixing groove 2. In order to increase the stability between the fixing groove 2 and the fixing block 3, rubber rings 5 are provided between the fixing groove 2 and the fixing block 3. The rubber rings 5 are fixedly installed on the inner surface of the fixing groove 2, and limiting holes 15 are symmetrically opened at both ends of the inner surface of the fixing groove 2. Grooves 7 are opened on the top and bottom ends of the fixing block 3. Limiting grooves 8 are symmetrically arranged on the inner surface of the grooves 7. Limiting blocks 9 are slidably connected in the limiting grooves 8. In order to make the limiting blocks 9 slide stably in the limiting grooves 8, sliding grooves 10 are symmetrically opened at the top and bottom ends of the limiting grooves 8. Sliding blocks 11 are symmetrically welded on the top and bottom ends of the limiting blocks 9. The sliding blocks 11 are slidably connected with the sliding grooves 10. Limiting rods 12 are symmetrically welded at one end of the limiting blocks 9. Springs 13 are sleeved on the limiting rods 12. The springs 13 have a certain elasticity. The two ends of the springs 13 are respectively fixedly connected to the limiting blocks 9 and the inner wall of the limiting grooves 8.

With continuous contact, the spring 13 is in a compressed state, and thus the winding post 4 is fixed on the fixing ring 1. By twisting the fastening bolt 19, the fastening bolt 19 is placed in the threaded hole 20, and thus the sealing plate 17 is fixed on the fixing ring 1.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0033] In actual application, first, the fixing block 3 on the winding post 4 is placed in the fixing groove 2 on the fixing ring 1, and the groove 7 and the hole 14 on the winding post 4 are aligned with the through hole 16 and the limiting hole 15 on the fixing ring 1, so that the winding post 4 is initially fixed on the fixing ring 1. Secondly, the rod 18 on the sealing plate 17 is passed through the through hole 16 and placed in the groove 7. Then the sealing plate 17 approaches the fixing ring 1, so that the bottom end of the rod 18 contacts the side wall of the limiting block 9. With continuous contact, the limiting block 9 slides into the limiting groove 8, the spring 13 is in a compressed state, and the limiting rod 12 on the limiting block 9 passes through the hole 14 and is in the limiting hole 15, and thus the winding post 4 is fixed on the fixing ring 1. Then, twist the fastening bolt 19 to place the fastening bolt 19 in the threaded hole 20, and thus the sealing plate 17 is fixed on the fixing ring 1.
