- the blade passes through the through hole or notch to cut the stem.
- the blade is sandwiched between a pair of arms and cuts a part of the fixed stem, so that the stem is deformed according to the rigidity of the stem, and the cutting position of the stem and the shape of the cut surface of the stem vary. It can be prevented from occurring. Therefore, the cutting position and the cut surface shape can be made constant.
- the through hole or notch extends from a clamping surface for clamping the stem of the arm to a surface on the opposite side of the clamping surface of the arm.
- the through-hole or notch extends from the clamping surface to a surface on the opposite side to the clamping surface. For this reason, since the through hole is formed independently on one of the pair of arms, for example, even if the size of the stem is large and the position where the pair of arms sandwich the stem changes, the through hole is formed by the through hole.

Abstract
Description
接木用の苗の茎の一部を挟持する開閉可能な一対のアームと、
上記茎の上記一部に対して進退可能に設けられると共に、上記茎を切断する刃と
を備え、
上記一対のアームの少なくとも一方は、上記刃が進退する方向に沿って上記アームの一部を貫通する貫通孔または切り欠きを有し、
上記貫通孔または切り欠きは、上記茎の上記一部に少なくとも一部が対向すると共に、上記刃の少なくとも一部が通ることを特徴としている。
上記貫通孔または切り欠きは、上記アームの上記茎を挟持する挟持面から、上記アームの上記挟持面に対して反対側の面まで延在している。
別の言い方をすると、上記貫通孔または切り欠きは、上記挟持面から、上記挟持面に対して反対側の面まで延在しているので、上記一対のアームの一方に形成した貫通孔または切り欠きだけで、刃の全部が通過可能な通路を画定できる。その結果、例えば、一対のアームが太い茎の一部を挟持することで、一対のアーム間の距離が広がっても、上記通路の形状は変化しない。したがって、上記茎の太さが変わっても、刃を茎に確実に到達させることができる。
上記刃が進退する方向から見たとき、上記貫通孔の形状は、上記刃の形状と略同一である。
上記刃が進退する方向から見たとき、上記刃は、y字状に形成されている。
上記苗切断装置を備えることを特徴としている。
51 穂木苗
52 台木苗
111,121,1111 刃
210,215,310 貫通孔
211,212,311,312,2111,2112,2113,2121,2122,2123 アーム
