摘要： A power tool includes a shaft locking assembly (121) and an electric motor (11). The shaft locking assembly includes a first state where a chuck (131) is restrained from rotating and a second state where the chuck is released to rotate. The shaft locking assembly includes multiple locking portions (2112) and an execution portion (2114). The multiple locking portions are formed on or connected to a drive shaft (111) or the chuck. The execution portion is optionally engaged with at least one locking portion. When the execution portion moves to a first position, the execution portion is engaged with the at least one locking portion such that the shaft locking assembly is in the first state. The electric motor includes a stop state where the first position is in the at least one locking portion when the electric motor stops.

摘要： 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.
