ELECTRIC POWER TOOL PROVIDED WITH THE BRUSH SHIFT MECHANISM STABILIZED ELECTRIC CONNECTING CONDITION

摘要

PURPOSE: An electric tool equipped with a current transition apparatus in which connection is stable is provided to maintain a stable connection state in the vibration and to improve durability. CONSTITUTION: A brush shift base(110) is combined with a stator of a motor. A brush carrier is combined with brush shift base and rotates at the regular angle. A brush holder(130) is installed in the brush carrier. A brush is combined with the brush holder and electrically touches to a commutator. A terminal strip(200) is combined inside the brush shift base and comprises a first terminal(210) connected to a coil of the stator and a second terminal(220) extended into two side to the brush holder.
