Abstract:
An electric tool includes a motor including a plurality of windings, a power circuit configured to selectively access a first power supply and a second power supply for supplying power for the motor, a connecting circuit including a switching device configured to enable the connecting circuit to have a first connection state and a second connection state, and a signal source configured to send a first control signal, when the power circuit accesses the first power supply, to the switching device so that the connecting circuit is in the first connection state, and send a second control signal, when the power circuit accesses the second power supply, to the switching device so that the connecting circuit is in the second connection state.

Claim (Index 6):
An electric tool, comprising:\n a motor comprising a first winding, a second winding and a third winding; a power circuit configured to selectively connect a first power supply and a second power supply for supplying power for the motor and comprising an output anode and an output cathode; a connecting circuit comprising:\n a first connecting circuit comprising a first switch and a second switch, wherein one of two connecting ends of the first winding is connected between the first switch and the second switch; \n a second connecting circuit comprising a third switch and a fourth switch, wherein the other one of two connecting ends of the first winding is connected between the third switch and the fourth switch; \n a third connecting circuit comprising a fifth switch and a sixth switch, wherein one of two connecting ends of the second winding is connected between the fifth switch and the sixth switch; and \n a fourth connecting circuit comprising a seventh switch and an eighth switch, wherein one of two connecting ends of the third winding is connected between the seventh switch and the eighth switch; and \n a signal source configured to send a first control signal, when the power circuit accesses the first power supply, to the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch and the eighth switch so that the first winding is connected between the output anode and the output cathode, and to send a second control signal, when the power circuit accesses the second power supply, to the first switch, the second switch, the third switch, the fourth switch, the fifth switch, the sixth switch, the seventh switch and the eighth switch so that the first winding and the second winding are connected between the output anode and the output cathode; wherein the connecting circuit is electrically connected with the power circuit and the motor, and the signal source is electrically connected with the connecting circuit.
