Abstract: A power tool includes an electric motor; a battery pack for providing a power supply; a switching circuit for outputting a power-on signal or a shutdown signal; a first switching device for controlling a power-on state of the electric motor; a second switching device for driving the electric motor to rotate; and a controller electrically connected to at least the first switching device, the switching circuit, and the second switching device. The controller is configured to, when the power-on signal is detected, control the first switching device and the second switching device to control, in a first working mode, the electric motor to rotate and when the shutdown signal is detected, control the first switching device and the second switching device to control, in a second working mode, the electric motor to rotate.

Abstract: A hand-pushed power tool includes a tool body including a working assembly, a control unit for controlling running of the working assembly, and a handle device. The handle device includes an operation member and a connecting rod assembly including a first connecting rod connected to the tool body. The first connecting rod includes a first lower rod portion and a first upper rod portion. The first upper rod portion is slidable relative to the first lower rod portion to a retracted position and an expanded position. The handle device further includes a detection device including a first detection element for detecting a telescopic state of the handle device, and a control device mounted to the operation member and electrically or communicatively connected to the first detection element. The control device is configured to control the control unit according to detection information from the first detection element.
