A kind of Shears for high branches structure-improved,The Shears for high branches include extension rod,Fixed jaw,Swing blade,Control member and clamping group； Wherein the sword plate portion movement of the swing blade includes downward swing opening state and upward swing shearing condition,Sword plate portion is tangent in the cutting plate portion of upward swing shearing condition Shi get Yu fixed jaw,Clamping group then include it is upper,Lower holder sets up the sword plate portion of what fixed jaw cutting plate portion and swing blade separately； Its feature mainly in the downward swing opening state of the sword plate portion what of the what swing blade,System enable sword plate portion extend downwardly set to extension rod setting axis between have an external-open angle； Thereby,In order to be formed by between amplifiable sword plate portion and the cutting plate portion of fixed jaw maximum shear opening amplitude,With relative increase, it can shear diameter degree.一種高枝夾剪改良結構 ， 所述高枝夾剪包括延伸桿、固定顎、旋擺刀刃、控制構件及夾持組；其中該旋擺刀刃之刃板部動作包括向下旋擺打開狀態及向上旋擺剪切狀態，刃板部呈向上旋擺剪切狀態時得與固定顎的切板部相切，夾持組則包括上、下夾座分設於固定顎切板部及旋擺刀刃的刃板部；其特點主要在於該旋擺刀刃的刃板部於向下旋擺打開狀態時，係令刃板部向下延伸設向與延伸桿設置軸線之間具一外開夾角；藉此， 俾可擴增刃板部與固定顎的切板部之間所形成的最大剪切開口幅度，以相對增加其可剪切徑度。
