A telescopic rod used for manual tool comprises an inner tube, an external tube sleeved to the inner tube, and a positioning component disposed to the external tube. The positioning component comprises a sliding block, a positioning bolt, and an operating button. The sliding block is slidably disposed to the external tube and has a push portion and a guide slot openly disposed to the push portion. The positioning bolt is movably pass through the guide slot of the sliding block in axial direction and abutted against the push portion of the sliding block. The operating button is connected to the sliding block through a connection member to drive the sliding block to move. Accordingly, when the sliding block is pulled by the operating button to axially move along the external tube, the push portion of the sliding block would push the positioning bolt to allow the bottom end of the positioning bolt to be released from a positioning hole of the inner tube. At this time, the relative position between the inner and external tubes can be adjusted to achieve the purpose of adjusting the length.一種用於手工具之伸縮桿,包含有一內管、一套設於內管之外管,以及一設於外管之定位組件,定位組件具有一滑塊、一定位栓,以及一操作鈕,滑塊可滑移地設於外管且具有一推頂部與一開設於推頂部之導溝,定位栓可軸向移動地穿設於滑塊之導溝且抵接於滑塊之推頂部,操作鈕藉由一連接件連接滑塊,用以帶動滑塊移動,藉此,當滑塊受到操作鈕之拉動而沿著外管之軸向移動時,滑塊之推頂部會推動定位栓,使定位栓之底端脫離內管之一定位孔,此時即可調整內、外管之間的相對位置,以達到調整長度的目的。20‧‧‧內管21‧‧‧內管身22‧‧‧定位孔23、24‧‧‧端蓋30‧‧‧外管31‧‧‧外管身32‧‧‧第一鏤空槽33‧‧‧第二鏤空槽34‧‧‧握把套35‧‧‧嵌槽40‧‧‧定位組件42‧‧‧滑塊422‧‧‧斜面424‧‧‧導溝425‧‧‧凸柱43‧‧‧操作鈕44‧‧‧連接件45‧‧‧彈片451‧‧‧第一水平段452‧‧‧第二水平段453‧‧‧傾斜段454‧‧‧固定孔455‧‧‧穿孔46‧‧‧定位栓462‧‧‧外凸緣47‧‧‧第一復位彈性件48‧‧‧第二復位彈性件50‧‧‧底座52‧‧‧蓋板53‧‧‧安裝槽54‧‧‧擋止壁55‧‧‧固定凸部56‧‧‧限位孔
