A gardening shear comprises a first shear blade, an actuation arm pivoted to the first shear blade, a second shear blade pivoted to the first shear blade, and a linking arm pivoted between the actuation arm and the second shear blade. The second shear blade has a bottom end provided with a sliding slot and a plurality of engaging slots communicated with the sliding slot. A switch device is installed in the actuation arm. As the switch device is located at a first usage place, one end of the linking arm is embedded in one engaging slot that is adjacent to a top end of the sliding slot so as to stop the linking arm from upward-downward sliding along the slide slot, thus enable the shear to perform a primary shearing operation on leaves of twigs. As the switch device is located at a second usage place, one end of the linking arm is allowed to slide both in upward and downward directions and be embedded in one of the engaging slots optionally, thereby changing the fulcrum of applied force to perform a stage cutting operation on leaves of stubby branches.一種園藝剪,包含有一第一剪刃、一樞接於第一剪刃之作動臂、一樞接於第一剪刃之第二剪刃,以及一樞接在作動臂與第二剪刃之間之連動臂,其中在第二剪刃之底端具有一滑槽與多數個與滑槽連通之卡槽,並且在作動臂內安裝有一切換裝置,當切換裝置位於一第一使用位置時,連動臂之一端會嵌卡在與滑槽之頂端相鄰之一個卡槽內而不會沿著滑槽上下滑移,此時即可對細枝葉進行一次剪切動作,當切換裝置位於一第二使用位置時,連動臂之一端可以沿著滑槽上下滑移且可選擇地嵌卡於其中一個卡槽內,以變換施力支點來對粗枝葉進行分段剪切動作。10‧‧‧園藝剪20‧‧‧第一剪刃30‧‧‧作動臂40‧‧‧握柄50‧‧‧第二剪刃60‧‧‧連動板70‧‧‧連動臂93‧‧‧控制栓
