The invention provides a retractable water extending probe rod structure,Mainly by means of a first telescopic rodOne second extension rod1. The first stopper1. Second limit pieceA hook body and a hammer body are relatively formed；The water extending probe with this creation has a beautiful appearance and is easy to receive,It has no problem of tightness and can be adjusted by one hand,And the water extending probe in this creation has no problem of elastic fatigue due to rubber aging,Moreover, this creation is made of stainless steel,There will be no rust,The first extension rod and the second extension rod are respectively provided with a first limiting member and a second limiting member,Therefore, it will not be damaged due to excessive length adjustment；And the scale set on the surface of the first and second extension rods of the invention is more convenient for the user to see the length unit when adjusting.本創作係提供一種可伸縮式之伸水探測棒結構，主要係藉由一第一伸縮桿、一第二伸縮桿、一第一限位件、一第二限位件、一鉤體及一錘體所相對構成；藉此本創作之伸水探測棒外觀精美且容易收納，且無鬆緊度之問題並可以單手操作調整，且本創作之伸水探測棒並無因橡膠老化產生彈性疲乏之問題，再者本創作為不銹鋼材料製成，不會有生鏽之問題，以及本創作之伸水探測棒伸縮的第一伸縮桿及第二伸縮桿兩末端分別設具有一第一限位件及一第二限位件，故不會因過度調整長度而造成損壞；且本創作之第一伸縮桿及第二伸縮桿表面所設之刻度更容易方便使用者調整時目視其長度單位者。
