ABSTRACT:
It is a water faucet, which mainly comprises a control rod, a valve stem, and a clutch assembly being mounted between the control rod and the valve stem. The clutch assembly can only be driven by the control rod to rotate an angle of 90.degree.. After the control rod rotating clockwise at a given angle, a timer will drive it counter-clockwise slowly toward original position thereof so as to supply water during a given period of time. The inlet end of the water pipe is connected with a plug-in pipe, of which the tail end is furnished with several water holes. The plug-in pipe is to be inserted into a plug valve seat in the water pipe so as to open a spring type of automatic plug valve, and to let water enter into the faucet.
