Abstract: An impact driver or impact tool includes a motor, a motor housing that houses the motor, a grip housing integrally provided with the motor housing, a hammer case is disposed frontward of the motor housing, a spindle rotated by the motor, a hammer housed inside the hammer case and configured to be rotated by the spindle, and an anvil housed inside the hammer case which anvil is configured to be impacted by the hammer. In this impact driver, a length from a rear end of the motor housing to a front end of the anvil (i.e., the front-rear length of a main body) is less than 128 mm.

Abstract: An electric tool, such as an angle driver, has a main tool body with a front portion and a rear portion positioned opposite to the front portion. The main tool body houses a motor configured to receive electricity to function as a drive source. A gear head is coupled with the front portion of the main tool body wherein the gear head has a spindle in communication with a motor axis of the motor via mesh-engagement of bevel gears associated with the motor axis. The spindle has with a cutter tool accessory attached thereto such that rotation of the motor axis produces a commensurate rotation of the cutter tool accessory. Battery attachment portions are associated with the rear portion of the main tool body and are configured to receive a corresponding set of batteries that provide electricity to power the motor.

Abstract translation: 诸如角度驱动器的电动工具具有主工具主体，其具有与前部相对的前部和后部。 主工具主体容纳配置为接收电力以用作驱动源的电动机。 齿轮头与主工具主体的前部联接，其中齿轮头具有通过与电机轴线相关联的锥齿轮的啮合而与马达的马达轴线连通的主轴。 主轴具有附接到其上的刀具附件，使得电动机轴的旋转产生刀具附件的相应旋转。 电池安装部分与主工具主体的后部相关联，并且被配置为接收提供电力以对电动机供电的相应的一组电池。
