The invention discloses a cutter handle capable of realizing composition of ultrasonic vibration and low-frequency vibration. According to the cutter handle, low-frequency vibration is realized by utilizing mechanical movement formed by a motor, double cams and a vibration sliding block structure, and ultrasonic vibration is realized by utilizing piezoelectric vibration energy converter consistingof piezoelectric ceramics and an amplitude-change pole; a high-frequency vibration mechanism and the low-frequency vibration mechanism of the cutter handle are connected through a low-frequency vibration shaft; and two kinds of vibration are coupled in a cutter handle axis direction; the cutter handle is compact in integral structure, proper in size and high in rigidity; the lower end amplitude-change pole is fastened with a machining tool through a standard spring clamp collet; three modes of ultrasonic vibration, low-frequency vibration and ultrasonic-low-frequency composite vibration; andultrasonic vibration machining modes of different modes can be realized according to different machining tools. The cutter handle is compact in structure and low in cost, and has a wide prospect in the aspect of research and application of an ultrasonic-low-frequency composite vibration machining technique.
