[0029] When the flow guide joint 5 rotates, the limiting plug 10 extends through the corresponding second limiting hole 9 and the first limiting hole 8, so that the limiting plug 10 can extend to one side of the flow guide joint 5 to block the flow guide joint 5, realizing the function of limiting the stroke of the flow guide joint 5 when it is deflected, avoiding the phenomenon of operation error when the pipeline is converted.
