HSK ultrasonic knife handle

The invention discloses an HSK ultrasonic knife handle which comprises an HSK knife handle body, a wireless electric energy transmission device, a hollow ultrasonic transducer and a dynamic balance ring. The hollow ultrasonic transducer is arranged at the head end of the HSK knife handle body. The wireless electric energy transmission device and the dynamic balance ring are symmetrically arranged on the HSK knife handle body. The HSK ultrasonic knife handle is ingenious in structural design, and the HSK knife handle body and the hollow ultrasonic transducer are reasonably combined into an integral structure, so that the HSK ultrasonic knife handle is different from a traditional knife handle of a complex structure and smaller in size; since no ultrasonic electric main shaft structure needs to be added, the application cost is reduced; and meanwhile the HSK ultrasonic knife handle can adapt to different hollow tool heads through a chuck and is high in flexibility so as to meet different machining function requirements. In addition, the wireless electric energy transmission device transmits ultrasonic energy in an electro-magnetic induction manner, the dynamic balance ring is arranged in an adaptive manner, contact is not needed, and working stability is effectively improved. The HSK ultrasonic knife handle has the advantages of being high in stability, rotating speed and precision, long in service life and the like, and is easy to widely use and popularize.
