After removing the single-headed through-thread bolt 9, the second nut 14, the upper pressing plate 10, and the lower pressing plate 11 are removed together. The flexible joint body 1 is set at the position where the feeder needs to be sealed and wound into a cylindrical structure to wrap the feeder that needs to be sealed. The dovetail groove 5 and the dovetail protrusion 4 are matched to realize the connection and fixation of the cylindrical structure.
