摘要： An automatic impact driver for applying a large torque to a tip chuck by only pressing down a casing so as to remove corroded screws etc. A cylindrical slider freely movable in an axial direction is disposed in the casing, a cam mechanism is installed in between the slider and the chuck, and the chuck is turned by applying an impact force on a plunger through the slider. Since the impact driver is constructed as described above, a loss of impact transmitting force is decreased as compared with a conventional structure in which the slider is directly struck by the casing.
摘要翻译：一种自动冲击驱动器，用于通过仅按压壳体以除去被腐蚀的螺钉等将大扭矩施加到尖端卡盘。可以在轴向方向上自由移动的圆柱形滑块设置在壳体中，凸轮机构安装在滑块和卡盘，并且通过在滑块上对柱塞施加冲击力来转动卡盘。由于冲击驱动器如上所述构造，所以与滑块直接撞击壳体的传统结构相比，冲击传递力的损失减小。
