A power tool includes a main housing, a drive mechanism, a working head, and a connection assembly. The connection assembly includes an input portion connected to the drive mechanism and an output portion connected to an output shaft. The connection assembly rotates the working head about a first axis relative to the main housing. The power tool includes a first transmission path. When the working head rotates about the first axis relative to the main housing, components in the first transmission path are allowed to deform or to be displaced along a direction of the first transmission path.

Power tool

A power tool includes an output assembly and a battery pack. The output assembly is disposed at an end portion of a first handle, the output assembly includes at least two output units spaced apart and used for connecting working accessories, and the output assembly is rotatable about a shift axis to shift an output unit among the at least two output units to a working position or a non-working position. The battery pack is disposed at a bottom of a body, the battery pack includes a standing surface through which the power tool is capable of standing, and when the power tool stands, a projection of a center of gravity of the power tool on the standing surface is in the standing surface.

An electric drill and an electric tool, including: a housing provided with an air inlet and an air outlet; a motor received in the housing, wherein the motor at least comprises a motor shaft; a drill bit, acting on a workpiece; the motor shaft is connected to the drill bit; a gearbox arranged in the housing for accommodating the transmission assembly; a fan supported by the motor shaft; wherein the gearbox is formed with a passage, and at least a part of a flow path of an airflow that enters the housing from the air inlet and flows out of the housing from the air outlet is provided on the passage.

Electric drill and electric tool

A power tool includes a main housing in which a drive mechanism is disposed and a working head connected to an end of the main housing and rotating relative to the main housing about a first axis. The working head includes an output shaft and the output shaft is driven by the drive mechanism to rotate about a second axis. The main housing is provided with a window portion and the window portion is configured to display an internal structure of the power tool.
