The invention provides a tool connecting structure, and relates to the technical field of machining. The tool connecting structure comprises an ultrasonic tool body, a wireless transmission and receiving device, an ultrasonic transducer and a grinding tool. The ultrasonic transducer comprises an amplitude-change pole and a piezoelectric vibrator. The piezoelectric vibrator is connected with the wireless transmission and receiving device. A connecting protrusion connected with the grinding tool and multiple second locking holes arranged in the peripheral side of the connecting protrusion are arranged on the bottom face of the second end of the amplitude-change pole. The first end of the amplitude-change pole is connected with the second end of the ultrasonic tool body through a connecting part. The grinding tool comprises a tool disc body, a connecting hole used for being connected with the amplitude-change pole is formed in the middle of the grinding tool, and multiple first locking holes corresponding to the
