A pair of stepless retractable high branch scissors comprises a pair of high branch scissors having a bottom pipe and a retracting pipe received in the bottom pipe, a retracting device and a retracting strip. The retracting device and the retracting strip are received in the retracting pipe. The retracting strip is defined with a plurality of stepless annular grooves. The retracting device includes a blocking element formed by two sliding blocks, each sliding block is provided with a positioning rib that is fixed to one of the stepless annular grooves, the sliding blocks can be abutted against or separated from each other so as to selectively restrict or allow the retracting strip to move, thus adjusting the length of the high branch scissors steplessly.一種可無段伸縮之高枝用剪,包含:一高枝用剪、一伸縮裝置以及一伸縮條,該高枝用剪包括一底管及容設於該底管內之一伸縮管,該伸縮裝置及該伸縮條均容設於該伸縮管內;藉由在伸縮條上設置密集的複數無段環槽,使得伸縮條於每一無段環槽上均能成為定位處,並配合伸縮裝置定位固定,其中,該伸縮裝置具有由二滑塊配合而成的一鎖檔件,該滑塊上之定位肋部可容置於其中一該無段環槽內而定位,並透過該二滑塊之靠抵或分開而選擇性地限制或允許該伸縮條位移,藉此達到無段調整高枝用剪之長度之目的。20‧‧‧高枝用剪21‧‧‧底管22‧‧‧伸縮管23‧‧‧控制件231‧‧‧手持部232‧‧‧開關部24‧‧‧固定長條25‧‧‧開關長條26‧‧‧剪刃部30‧‧‧伸縮裝置35‧‧‧ㄇ型片40‧‧‧伸縮條
