AUTOMATIC WATERER

PURPOSE: To provide an automatic waterer capable of attaching or detaching an operating rod and a coupler body socket by one touch. CONSTITUTION: This automatic waterer is composed of a coupler body plug, a receiving plate for fixing the coupling body, a coupler body socket constituted detachably to the coupler body plug, a hose attaching part screwed at the rear end of the coupler body socket, a valve part arranged in the space formed from the hose attaching part and the recessed part of the coupler body socket and an operating rod installed in a through hole formed through the coupler body socket and the coupler body plug and having the rear end fixed to the valve body. Since the operating rod is also integrally pulled out by removing the coupler body socket from the coupler body plug, cleaning operation of the water supply equipment is readily carried out.
