Novel tartar clearing device

The invention relates to the field of tartar clearing device design, and especially relates to a novel tartar clearing device. The device comprises a tooth cleaning needle seat and a connection bar. A U-shaped groove is provided on the bottom end of the tooth cleaning needle seat. The top of the connection bar is provided with two semispherical convex parts. The connection bar is connected to the U-shaped groove of the tooth cleaning needle seat through the semispherical convex parts. According to the invention, through elastic deformation of the two semispherical convex parts on the connection bar, the tooth cleaning needle seat connected through the U-shaped groove and the connection bar can perform reciprocating movements along clockwise and counterclockwise directions around the main axis of the tooth cleaning needle seat. Power is provided by a motor. The movement of the tooth cleaning needle seat is the combination of the reciprocating movement and vibration produced by the motor. Therefore, relatively
