    • A baton-like device is provided with a hollow telescopic ram or bolt member which can be driven to extend out of a barrel or trunk portion of the baton. The driving force is produced by a source of gas under pressure, which in preferred embodiments, takes the form of explosive cartridges and which can be repeatedly and automatically operated in a manner similar to an automatic shot gun. The force with which the ram is driven can be modulated using a pressure by-pass or by selection of the cartridges, or both. In order to reduce the risk of a fatal impact, the tip of the ram is provided with a blunt knob which can further include an inflatable cushion like member which is supplied with air or gas as the ram is displaced out of the barrel. The knob is removable allowing projectiles such as tranquilizer darts to be launched by loading the projectile into the hollow bolt and catapulting them towards a target or targets. Alternatively, the knob can be replaced with a chisel-like cutting tool and used as an emergency cutter in the event of a vehicle accident.
    • 一个棒棒状装置设置有一个中空的伸缩式压头或螺栓构件,该构件可以被驱动以延伸出指挥棒的一个桶或躯干部分。 驱动力由加压气体源产生,在优选实施例中,该气体采取爆炸盒的形式,并且可以以与自动喷枪相似的方式反复自动地操作。 可以使用压力旁路或通过选择墨盒或两者来调节压头驱动的力。 为了减少致命冲击的风险,冲头的尖端设置有钝头旋钮,其可以进一步包括可膨胀的衬垫状构件,当冲头从筒体移出时供给空气或气体。 旋钮是可拆卸的,通过将射弹装载到中空螺栓中并将其弹射到目标或目标,可以发射诸如安抚飞镖的射弹。 或者,可以用凿状切割工具代替旋钮,并在车辆事故时用作紧急切割器。
