A kind of washing head any direction adjustment of long-neck watering device prevents revolution from constructing,It is to include at the water supply link component front end at a linking water source and the Hou end of a washing head,It is respectively provided with the urgent adapter tube unit for linking a water pipe both ends therebetween,And the bendable rod that an one end protrudes into washing head is installed in the water pipe,The other end of bendable rod is enabled to protrude into be fixed in water supply link component front end and be embedded and make on the anti-rotation block that can not be rotated again,It is equipped with the channel passed through for water flow on anti-rotation block again simultaneously,It is enabled to penetrate bending Hou that any direction and angle are done to bendable rod,The scheduled watering direction of washing head can arbitrarily be changed,It is also fixed in conjunction with anti-rotation block through bendable rod simultaneously,Allow bendable rod will not twist backswing the phenomenon that,So that the washing head in watering direction is adjusted,It keeps set watering direction and sprinkler operation more can smoothly be carried out.一種長頸灑水裝置之灑水頭任意方向調整的防止回轉構造,是包括一銜接水源的供水連結元件前端與一灑水頭的後端處,各設有其間連結一水管兩端的緊迫接管單元,並在該水管內容設一其一端伸入灑水頭內的可彎曲桿,再令可彎曲桿的另一端伸入固定在供水連結元件前端內嵌設而使無法轉動的一止轉塊上,同時又在止轉塊上設有可供水流通過的通道,使能透過對可彎曲桿做任意方向與角度的彎曲後,可任意改變灑水頭預定的灑水方向,同時也透過可彎曲桿與止轉塊結合固定,讓可彎曲桿不會發生扭轉回擺的現象,使得調整好灑水方向的灑水頭,保持既定的灑水方向而讓灑水作業更能順利的進行。
