A gardening shears includes two handles, a first shear blade connected to one handle and providing a suspension arm portion, a linking rod connected to the other handle, a second shear blade coaxially pivoted to the first shear blade and the linking rod and providing an elongated slot, and a control unit including an arched guide member fixedly connected with its one end to the linking rod and a guide wheel pivotally connected to the suspension arm portion of the first shear blade with a guiding protrusion thereof inserted into the elongated slot of the second shear blade. Thus, when opening and closing the handles, the mating arrangement of the arched guide member, the guide wheel and the elongated slot of the second shear blade enables the first and second shear blade to implement the shearing action twice.一種園藝剪,包含有一第一剪刃、一連動桿、一第二剪刃,以及一控制單元,第一剪刃接設於一握柄且具有一懸臂部,連動桿接設於另一握柄,第二剪刃以同軸方式樞接於第一剪刃與連動桿且具有一溝槽,控制單元具有一弧形導引件與一可滾動地設於弧形導引件之導輪,弧形導引件之一端固定於連動桿,導輪樞接於第一剪刃之懸臂部且藉由一導引凸部嵌設於第二剪刃之溝槽內,藉此,在展開與收合握柄的過程中,利用弧形導引件、導輪,以及第二剪刃之溝槽之間的搭配,可以讓第一、第二剪刃進行兩次的剪切動作,以達到操作省力及提升效率的目的。20‧‧‧握柄40‧‧‧第一剪刃41‧‧‧第一刃部43‧‧‧懸臂部50‧‧‧第二剪刃51‧‧‧第二刃部52‧‧‧受抵部53‧‧‧溝槽60‧‧‧控制單元61‧‧‧弧形導引件62‧‧‧齒部63‧‧‧導輪64‧‧‧齒輪65‧‧‧輪蓋67‧‧‧導引凸部
