    • An object of the present invention is to provide a switching mechanism of an ejector which is simple to operate and in which projecting portions on a gun are minimized. A hammer is pivoted to return to the original position when a breech is opened after a gun is fired, whereby a projection of the hammer abuts against a head of a trip rod. Thus, the trip rod is shifted longitudinally and the ejector mechanism is operated. A spiral guide which is engaged with the trip rod is formed on a selector button adjacent to the trip rod, and a groove for rotation is formed on an end surface of the selector button. When the selector button is rotated, the trip rod is shifted in the direction which intersects with its longitudinal direction, thereby switching between a state in which the projection abuts against the head and another state in which they are not abutted against each other.
    • 本发明的目的是提供一种喷射器的切换机构,该切换机构操作简单,其中喷枪上的突出部分最小化。 在枪被击发后,当枪膛打开时,锤被枢转以返回到原始位置,由此锤的突起抵靠跳闸杆的头部。 因此,跳闸杆纵向移动并且喷射器机构被操作。 与脱扣杆接合的螺旋引导件形成在与脱扣杆相邻的选择器按钮上,并且在选择按钮的端面上形成用于旋转的槽。 当选择按钮旋转时,跳闸杆沿与其纵向方向相交的方向移动,从而在突起抵靠头部的状态和不彼此抵接的状态之间切换。
