A power tool comprises a motor, a lighting power source and a shell component for limiting an axial ling and supporting the motor and the lighting power source. The power tool also comprises a power supplying circuit with a light source transmitting the energy to the light source and a lighting component supplying the light. The light source and the lighting power source are distributed by the axial ling at intervals. In addition, the power tool also comprises a light source bracket supported by the shell component; the light source bracket supports the light source and a part of the power supplying circuit; in that way, one end which is not supported by the power supplying circuit extends to the light source bracket; the bracket is electrically coupled to the lighting power source.
