    • An improved structure of a sand blast gun includes a body, a guide tube accommodated in the body in a longitudinal direction, and a stop valve disposed in a radial direction. The stop valve has two guide posts. A shaft having a sleeve fitted on the outside straddles over upper portions of the guide posts. The guide posts are respectively fitted with pressure springs and inserted into holes of the body. An urging top end is firstly fixed on a center of a securing plate that is screwably mounted at the bottom side of the guide posts such that the urging top end extends into a radial round hole of the body to urge against a catgut tube to close the passage. When a trigger of the sand blast gun is pulled, it pushes the shaft and the guide posts to cause the pressure spring to retract to thereby cause the securing plate on the bottom of the guide posts and the urging top end to displace outwardly. The urging top end then disengages from the catgut tube to open the sand blast passage to achieve control of operation of sand blasting.
    • 喷砂枪的改进的结构包括主体,沿纵向方向容纳在主体中的引导管和沿径向设置的截止阀。 截止阀有两个导柱。 具有安装在外部的套筒的轴跨过导柱的上部。 导柱分别装有压力弹簧并插入人体的孔中。 首先将推动顶端固定在固定板的中心,该固定板的中心可旋转地安装在导柱的底侧,使得推动顶端延伸到身体的径向圆形孔中,以推动抵达肠管以闭合 通道。 当喷砂枪的扳机被拉动时,它推动轴和引导柱以使压力弹簧缩回,从而使导板的底部上的固定板和推动顶端向外移位。 推动顶端然后与肠管分离,打开喷砂通道,以实现喷砂操作的控制。
