  • Patent number: 10639758
    Abstract: A power tool includes a tool main body including a first motor for outputting power to a tool attachment and a dust collecting device. The dust collecting device includes a fan, a second motor for driving the fan to rotate so as to generate absorbing force, a connecting assembly for connecting the dust collecting device with the tool main body detachably, a dust collecting housing connected movably with the connecting assembly in a front and rear direction. The second motor includes a stator and a rotor being capable of rotating relative to the stator about a first axis substantially perpendicular to the front and rear direction. The dust collecting housing is formed with a first containing chamber for containing the fan and a second containing chamber for containing dust absorbed by the dust collecting device.
