Abstract
【解決手段】 ハンドルはエンド・エフェクターを発射させるために必要とされる力の所要量を減少するために多数回の発射ストロークを行なう。一定の発射部材が上記の発射動作を伝達するためにエンド・エフェクターまで一定の細長い軸部の中を往復動する。さらに、一定の後退用のばねが完全な発射動作の後に上記発射部材を後退させる。また、各発射ストロークの間に、発射トリガーが解除または放出されると、一定の抗バックアップ機構が一定の電気的なアクチュエータ(例えば、電気活性なポリマーのアクチュエータ)を活性化し、このアクチュエータは一定のハンドルに物理的に取り付けられていて、上記発射部材を結合してその偶発的な後退を阻止する。
