Similarly, pulling connector 2 7 outward can connect the internal thread 2 14 to the external pipe fitting. Finally, different connectors can be selected for connection according to the size of the pipe fitting.

[0040] When it is necessary to control the internal flow, the knob 209 is turned, which causes the rotating shaft 208 to rotate. The rotation of the rotating shaft 208 causes the helical gear 207 to rotate, which in turn causes the helical gear 206 to rotate. The rotation of the helical gear 206 causes the rotating shaft 205 to rotate, so that the flow-blocking ball 202 can rotate with the rotating shaft 205, thereby realizing the control of the internal flow.
