Medical dental grinding apparatus

A medical dental grinding apparatus, comprising an apparatus body (1), wherein the interior of the apparatus body (1) is of a hollow structure, an upper end surface of the apparatus body (1) is symmetrically provided with two holes, and a lower end surface is designed as an opening;

• an air pipeline (2), a clamping mechanism (3), and a grinding mechanism (4) are provided in the apparatus body (1);
• a clamping port of the clamping mechanism (3) extends out of the apparatus body (1) through the opening of a lower end of the apparatus body (1);
• the grinding mechanism (4) is located on the opening of the lower end inside the apparatus body (1);
• the air pipeline (2) comprises an air inlet pipeline (21), an air outlet pipeline (22), and a U-shaped connection pipeline (23);
• lower ports of the air inlet pipeline (21) and the air outlet pipeline (22) are respectively fixedly connected to two ports of the U-shaped connection pipeline (23), and an upper port of the air inlet pipeline (21) penetrates through one of the twos holes on the upper end surface of the apparatus body (1) and that an upper port of the air outlet pipeline (22) penetrates the other of the two holes on the upper end surface of the apparatus body (1);
• an upper port of the air outlet pipeline (22) is provided with an external thread and a silencer (5) is threadedly connected to the upper port of the air outlet pipeline (22);
• a plane where the air pipeline (2) is located is perpendicular to a plane where the clamping mechanism (3) is located;
• the grinding mechanism (4) comprises a turbine fan (41) rotatably provided inside the U-shaped connection pipeline (23) and a plurality of grinding heads in transmission connection with the turbine fan;
• the grinding heads are all located below the U-shaped connection pipeline (23);
• and when the clamping mechanism (3) clamps a notch part to be ground, the clamping port thereof corresponds to a position of the grinding head.
