The utility model relates to the technical field of ultrasonic dental descalers, and discloses an ultrasonic dental descaler with a bunching function, which comprises a body of the ultrasonic dental descaler, a
handle and a connecting wire, one end of the connecting wire is connected with the
handle, and the other end of the connecting wire is connected with the body. The end, away from the
machine body, of each connecting arm is provided with an elastic buckle with a C-shaped section, the arms can be embedded into the elastic buckles, four supporting legs distributed in the circumferential direction are arranged on the circumferential side of the lower surface of the
machine body, and the sections of the supporting legs are L-shaped, and the connecting wires can be wound around the supporting legs. The lower surface of the
machine body is provided with a wire bunching
assembly used for driving the four supporting legs to move towards the sides away from each other and then tensioning the wound connecting wire. A connecting wire is wound around the
peripheral sides of the four supporting legs distributed in the circumferential direction, the wound connecting wire is tensioned through the wire bunching
assembly, and at the moment, the connecting wire can be wound on the lower surface of the machine body. And finally, the
handle and the connecting wire can be stored in order.
