Preferably, the sleeve is fixedly connected to the right side of the second joint and is communicated with the corrugated pipe body.

Preferably, the threaded pipe is fixedly installed outside the installation groove, and the top end of the threaded pipe is provided with an external conical surface matched with the threaded conical surface.

Preferably, the thread groove is engaged with a thread on the outside of the threaded pipe, and the sleeve is threadedly coupled with the threaded pipe.

Preferably, the thread taper surface and the thread groove form a connecting structure, and the length of the connecting structure is equal to that of the threaded pipe.

Preferably, the mounting piece is in threaded connection with the mounting groove, and the diameter of the hole formed in the sleeve is the same as that of the mounting groove and corresponds to that of the mounting piece.

After the structure more than adopting, the utility model has the advantages of it is following: this fine bellows of button head ironware glass is through setting up sleeve pipe and screwed pipe threaded connection to through setting up sleeve pipe and second articulate, make a plurality of bellows be convenient for connect from beginning to end, constitute connection structure through setting up screwed pipe and thread groove and the screw thread conical surface, make two bellows be convenient for realize connecting through thread engagement, identical through setting up seal groove and sealing washer, make the junction leakproofness good, pass sleeve pipe and screwed pipe through setting up the installed part, make the bellows connection more stable.
