An armature circuit in an electric tool and a power socket of the electric tool using the armature circuit. The armature circuit comprises a power supply and a motor. Two electrodes of the power supply are each provided with a connection structure connected to an output part. One connection structure is a multi-contact on/off controllable movable contact structure, and the other one is a double-faced multi-contact structure. According to the armature circuit, the internal resistance of the armature circuit of the motor is greatly reduced, the hardness of running characteristics of the motor is enhanced, and the working efficiency of the tool is improved; due to decreasing of the internal resistance, the current loss of the armature circuit is reduced, and the temperature rise of an electric appliance and contacts is reduced; and with the same working efficiency, by means of the armature circuit, the battery capacity can be saved, and the battery cost is reduced. |
