The sealing ring positioning structure 5 includes a limiting plate 8, a sealing ring positioning shaft 9, and a top material structure 10. The top material structure 10 includes an installation groove 11, a cylinder 12, a through hole 13, an installation cavity 14, a limiting block 15, a top pin 16, an inclined surface 17, a double inclined surface top block 18, and a compression spring 19. The outer surface of the rotating shaft 7 away from the geared motor 4 is fixedly connected to the middle of the outer surface of the rear end of the sealing ring positioning shaft 9.

[0029] A coupling is provided between the rotating shaft 7 and the geared motor 4. One end of the outer surface of the rotating shaft 7 is fixedly connected to one end of the outer surface of the output shaft of the geared motor 4 through the coupling. A bearing is provided between the rotating shaft 7 and the concave bracket 2, and the rotating shaft 7 is rotatably connected to the concave bracket 2 through the bearing. The limiting plate 8 is fixedly installed on the outer wall of the rear end of the sealing ring positioning shaft 9. The through hole 13 is opened in the middle of the upper outer surface of the sealing ring positioning shaft 9. The mounting groove 11 is opened on the rear side of the middle of the through hole 13. There are two sets of mounting cavities 14, which are located at the upper and lower ends of the through hole 13. The cylinder 12 is fixedly installed in the mounting groove 11. One end of the outer surface of the piston rod in the cylinder 12 is connected to the double inclined top block. The middle part of the outer surface of the rear end of the ejector pin 16 is fixedly connected, and the inclined surface 17 is opened at the lower part of the outer surface of the ejector pin 16 near the double inclined surface of the ejector pin 18. The ejector pin 16 passes through the mounting cavity 14. The limiting block 15 and the compression spring 19 are both located in the mounting cavity 14. The limiting block 15 is fixedly installed on the outer wall of the ejector pin 16, and the compression spring 19 is movably sleeved on the outer wall of the ejector pin 16. The compression spring 19 is fixedly installed between one side of the outer surface of the limiting block 15 and one end of the mounting cavity 14.
