摘要： A power tool includes a brushless motor having a stator and a rotor, which includes a rotary shaft extending in a front-rear direction of the power tool. The rotary shaft rotates a spindle that extends in an up-down direction of the power tool. A fan is fixedly coupled to the rotary shaft and rotates therewith. A switch is disposed rearward of the brushless motor and a controller is disposed rearward of the switch in the front-rear direction. A battery pack is disposed rearward of the controller. A main-body housing houses the brushless motor, the switch and the controller. The main-body housing includes a first tubular part, which houses the brushless motor, and a second tubular part, which houses the switch. The diameter of the second tubular part is smaller than the diameter of the first tubular part.

摘要： 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.

摘要： A power tool includes a clamp shaft for clamping a tool accessory to the power tool and a clamp shaft holding mechanism for selectively locking the clamp shaft to hold the clamp shaft in a position that secures the tool accessory on the power tool. The power tool also includes a lever for shifting the clamp shaft holding mechanism between clamped and unclamped states. The lever is configured such that when an operator grasps the lever and moves it toward a position for releasing the tool accessory, the lever and the operator's hand move away from the tool accessory.
