[0024] The specific operation is as follows. When in use, when the pipe to be sealed is thin, the main thin tube sleeve 1 and the auxiliary thin tube sleeve 2 can be used to seal the pipe. When the pipe to be sealed is thick, the main thick tube sleeve 304 and the auxiliary thick tube sleeve 305 can be used to seal the pipe. When using any one of the close-seam structures, the other one can be rotated around the rotating shaft 302 through the main fixing rod 301 or the auxiliary fixing rod 303 until the clamping column 307 on the main thin tube sleeve 1 is clamped and connected with the clamping groove 306 on the surface of the main thick tube sleeve 304, so that the device can be folded for easy use.
