A Shear with a drug-supplying device comprises a shear, a drug-supplying device having a plate, a nozzle, and a pipe. The shear has a seat with a passage, a handle with a trigger, a moving cutter with a knife mounted pivotally with the seat, a first rope and a second rope. The first end of the first rope and the second rope is connected with the trigger. The second end of the first rope is connected with the moving cutter. The second end of the second rope is connected with the plate. The first end of the pipe is communicated with the passage, the second end of the pipe is communicated with the nozzle. Thus, the vine will be died and eliminated because using this invention shear to cut the vine will also to drug at its wounded place simultaneously.一種附有供藥裝置之剪具,係由一剪具、一有壓板和供嘴的供藥裝置和一輸液管所構成;剪具有一設有一通道的切板部、一有一扳機的操控部、一有一刀刃並與切板部樞組的旋擺刀刃部、一第一傳動索和一第二傳動索;第一傳動索與第二傳動索之一端嵌置於扳機,第一傳動索之另端結合於旋擺刀刃部,第二傳動索之另端結合於供藥裝置之壓板;輸液管一端結合於切板部的通道,另端結合於供嘴;藉由上述構造,使本發明的新剪具,可將藤蔓植物剪斷、挫傷並同時施藥而徹底的將藤蔓植物滅除者。1‧‧‧剪具11‧‧‧桿件111‧‧‧第一開放端112‧‧‧第二開放端113‧‧‧通孔12‧‧‧切板部120‧‧‧夾持面121‧‧‧通道122‧‧‧第一樞軸123‧‧‧導桿13‧‧‧操控部130‧‧‧凹槽131‧‧‧握把132‧‧‧扳機133‧‧‧第二樞軸134‧‧‧第一彈性件135‧‧‧凹槽136‧‧‧卡槽14‧‧‧旋擺刀刃部140‧‧‧刀刃141‧‧‧夾齒部142‧‧‧第二彈性件143‧‧‧導槽144‧‧‧結合孔15‧‧‧第一傳動索151‧‧‧卡制體16‧‧‧第二傳動索2‧‧‧供藥裝置20‧‧‧背架201‧‧‧第三樞軸202‧‧‧壓板21‧‧‧容器211‧‧‧開口212‧‧‧導孔22‧‧‧蓋件23‧‧‧連通管230‧‧‧閥孔231‧‧‧滴流管232‧‧‧閥體233‧‧‧第三彈性件234‧‧‧活塞235‧‧‧按鈕24‧‧‧控制件241‧‧‧止漏體242‧‧‧第四彈性件243‧‧‧供嘴244‧‧‧閥孔245‧‧‧止漏件246‧‧‧孔3‧‧‧輸液管
