包括第一剪切部分及第二剪切部分的剪刀
摘要：
本发明关于一种剪刀，尤指修枝剪或修剪机(1)，包括第一剪切部分(3)及第二剪切部分(3′)。第一及第二剪切部分(3，3′)的每一个具有设置在枢纽(7)相对侧的切割刀片(11，11′)及轴或杠杆臂(5，5′)，枢纽(7)可旋转地将第一与第二剪切部分(3，3′)相互连接；剪刀进一步包括作用于第一及第二剪切部分(3，3′)的层压的或扁平的弹簧元件(27)，以将剪刀移动到开启位置。层压的或扁平的弹簧元件(27)包括固定地配置于或配备于第一剪切部分(3)的第一部分(27′)、及作用于第二剪切部分(3′)的弹性地配置的第二部分(27″)。为了在第二剪切部分(3′)的接触表面上提供没有或只有很小的摩擦力的层压的或扁平的弹簧元件(27)的运动，以避免噪音或磨损的发生，第二剪切部分(5′)在接触区域包括圆形表面或曲面，该接触区域构成第二剪切部分(5′)与层压的或扁平的弹簧元件(27)之间的碰触区域。
摘要（英）：

The invention relates to shears, in particular pruning shears or secateurs (1), comprising a first shear part (3) and a second shear part (3´). Each of the first and second shear parts (3, 3´) have a cutting blade (11, 11´) and a shaft or lever arm (5, 5´) which are arranged at opposite sides of a pivot (7) which rotatably connects the first and second shear parts (3, 3´) with each other. The shears further comprise a laminated or flat spring element (27) acting up-on the first and second shear parts (3, 3´) to move the shears on to an open position. The laminated or flat spring element (27) comprises a first portion (27´) fixedly arranged at or allocated to the first shear part (3) and a flexibly arranged second portion (27´´) acting on the second shear part (3´). In order to provide a movement of the laminated or flat spring element (27) on a contacting surface at the second shear part (3´) without or with only very low friction, thus avoiding occurrence of noise or abrasion, the second shear part (5´) comprises a rounded surface or curve at a contraction area which constitutes the touching zone between the second shear part (5´) and the laminated or flat spring element (27).
