摘要： In a centrifugal chamber 9, an elastic rotation shaft 30 and a high-rigidity rotation shaft 34 extend coaxially. When a rotor selected from an angle rotor 17 and a swing rotor 36 which have different sizes and shapes is set in the centrifugal chamber 9, an optimal shaft is connected automatically to the selected rotor. The angle rotor 17 having a low tendency toward mass eccentricity is supported and rotated by the elastic rotation shaft 30 for high-speed rotation. The swing rotor 34 having a high tendency toward mass eccentricity is supported by the high-rigidity shaft 34 for low-speed rotation. Rotation torque is transmitted to the swing rotor 34 from the elastic rotation shaft.

摘要： A charging signal Vi responding to a charging current is inputted to one input terminal (−) of an operational amplifier 95 forming a comparator and a setting signal Vr corresponding to a setting current value is inputted to the other input terminal (+) of the operational amplifier 95. When the charging signal Vi is not higher than the setting signal Vr, a charging stop signal is generated from the output terminal of the operational amplifier 95 to interrupt a switch unit 4. A starting signal Vcc larger than the setting signal Vr applied to the other input terminal (+) is applied to the one input terminal (−) of the operational amplifier 95 through a condenser 94 till a prescribed time elapses from the start of a charging operation to generate a charging start signal from the output terminal of the operational amplifier 95 and electrically conduct the switch unit 4.

摘要： A tool bit holding device for use in percussion apparatuses such as electrically operated hammers is provided. The device includes a tool bit carrier, a front hand-operated grip, and a rear hand-operated grip. The front hand-operated grip is supported by the tool bit carrier so as to be movable in a lengthwise direction and a circumferential direction of the tool bit carrier. The rear hand-operated grip is installed rotatably on a hollow cylinder connected to a casing of the hammer. The removable of a tool bit from the tool bit carrier is accomplished by moving the front grip in the lengthwise direction and then turning it in the circumferential direction to release engagement between the tool bit and the tool bit carrier. The angular orientation of the tool bit carrier relative to the casing of the hammer is accomplished by turning the rear grip relative to the tool bit carrier to shift a angular relation between the tool bit carrier and the casing of the hammer.
摘要翻译：提供了一种用于诸如电动锤的冲击装置的工具头保持装置。该装置包括工具头托架，前手柄和后手柄。前手柄由工具头托架支撑，以便能够沿刀具承载件的长度方向和圆周方向移动。后手把手可旋转地安装在连接到锤的壳体的中空圆柱体上。通过沿长度方向移动前把手，然后在圆周方向上转动工具刀头，可以从工具刀架移除刀头，以释放工具刀头和刀头托架之间的接合。相对于锤的壳体，工具头托架的角度取向是通过相对于工具头托架转动后把手来移动工具头托架和锤的壳体之间的角度关系而实现的。
