ジに設けたキー溝の位置が変化することに対して、摺動
キーを移動させることで対応するようにしている。This replacement jig is provided with a half-mounting donut-shaped locking projection on the upper surface of the jig body, into which the V groove of the holder fits, and fits in the key groove of the holder at the lowest position of the locking projection. The sliding key to be removed is attached so as to be slidable in the direction orthogonal to the locking ridge. In the proposed replacement jig, the position of the key groove provided on the flange of the holder changes when the holder is vertically fitted and engaged with the locking ridge when tightening the pull stud bolt and the cutting tool. This is dealt with by moving the sliding key.
しかし、上記のようにキー溝の位置変化に合せて摺動キ

ルダのＶ溝15の底面17に当接し、半円形溝３の一方の傾
斜面６がフランジ13のテーパ面18と面接触するため、ホ
ルダＡは安定した姿勢でセットされる。In this state, the upper surface 4a of the one protruding portion 4 of the replacement jig contacts the bottom surface 17 of the V groove 15 of the holder, and the one inclined surface 6 of the semicircular groove 3 makes surface contact with the tapered surface 18 of the flange 13. Therefore, the holder A is set in a stable posture.
一方、ホルダＡの向きを入れ換える場合は、第４図に示
