PURPOSE: A tooth brush capable of adjusting its head blade is provided to make optimized tooth brushing possible by freely adjusting an angle of both wing part and a center part by a user. CONSTITUTION: A tooth brush capable of controlling a head wing part comprises a head center unit(11), a left wing(12), a right wing(13), a slide control part(14), a linear motion transfer unit, and a wing angle control unit. The linear motion transfer unit is connected to a slide control part. The linear motion transfer unit transfers a linear motion of a slide control part to the head part. The wing angle control unit converts the linear motion to a motion to control an angle of the left wing, the right ring, and the head center part. |
