A kind of long-neck watering device that can arbitrarily adjust washing head direction,At the Hou end of the hand handle front end and a washing head that are connected water source including one,It is respectively provided with the adapter tube unit for linking a water pipe therebetween,And be installed in the what water pipe one end end end protrude into what adapter tube unit,And the bendable rod of rotation is prevented on the rotation prevention portion with fitting portion and in energy build-in what adapter tube unit,It is enabled to allow water pipe that do curving for any angle and curvature through the bendable rod,And then water pipe end is allowed to connect the washing head set,The adjustment of any direction sprinkling can be carried out,Simultaneously also because bendable rod has the mechanism of anti-rotation allow water pipe will not twist backswing the phenomenon that,Allow adjust watering direction washing head,Even if when user, which rotates hand handle, changes watering direction,It will not still twist and the problem of backswing because the gravity of washing head influences.一種可任意調整灑水頭方向的長頸灑水裝置，包括一銜接水源的手把前端與一灑水頭的後端處，各設有其間連結一水管的接管單元，並於該水管內容設一其一端端末伸入於接管單元內、並具有嵌合部而能嵌固於接管單元內之止轉部上而防止轉動的可彎曲桿，使能透過該可彎曲桿讓水管可以做任意角度與曲度的彎轉，進而讓水管末端接設的灑水頭，可以進行任意方向噴灑的調整，同時也因可彎曲桿具有防轉的機制而讓水管不會發生扭轉回擺的現象，讓調整好灑水方向的灑水頭，即使因使用者轉動手把而改變灑水方向時，仍不會因灑水頭的重力影響而發生扭轉及回擺的問題。
