  "textContent": "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.",
