ABSTRACT:
A spindle used in an ultrasonic machine for transmitting vibration to a working tool of the ultrasonic machine is disclosed. The spindle includes a main body, a rotor disposed in the main body, an elastic clamping unit disposed in the rotor, a vibrating unit having one end thereof connected to the inner wall of the rotor while the other end connected to the elastic clamping unit, and a pre-pressure unit penetrating the rotor and one end thereof connected to the elastic clamping unit to provide the elastic clamping unit with rigidity against the rotor, thereby making the elastic clamping unit provide pre-pressure to the vibrating unit which further provides the elastic clamping unit with vibration against the rotor. The present invention further provides a flexible hinge for the spindle.
