PROBLEM TO BE SOLVED: To provide a load-reducing mechanism of horticultural bundler, for reducing an operation load at a step for binding a bundling tape with a staple, which can reduce the operation load on bundling.SOLUTION: This load-reducing mechanism of horticultural bundler is characterized by dividing the second engaging portion 18b from the strike of a staple to the finish of bending after the operation of the first engaging portion 18a until closing a clincher arm 2, among the engaging portion 18 of an operation link 4 to be engaged with the engaging portion 7 from an opened state to a bundled state, into a previous step engaging portion 20 for moving from the strike of the staple to the bending-start of the staple and a post step engaging portion 21 for moving from the bending start of the staple to the bending finishing time, forming the previous step engaging portion 20 at a steep angle to the final end of the first engaging portion 18a, and forming the post step engaging portion 21 at a gentle angle to the previous step engaging portion 20.COPYRIGHT: (C)2007,JPO&INPIT【課題】結束時の操作荷重を軽減させる。【解決手段】開放状態から結束までの間に上記係合部7に対して係合する操作リンク4の係合部18のうち、上記クリンチャアーム2が閉じるまでの第1の係合部18aに続いてステープルが打ち出されてから折り曲げが終了するまでの第2の係合部18bを、ステープルを打ち出してからステープルが曲り始まるまでに移動する前段係合部20と、ステープルが曲り始めてから曲り終わるまでに移動する後段係合部21とに分け、前段係合部20を第1の係合部18aの終端に対して急角度に形成し、後段係合部21を前段係合部20に対して緩やかに形成した。【選択図】図7
