The tool holder 22 comprises a frame 221, the frame 221 comprises a through groove structure, the tool bit 21 is installed through the groove structure, a clamping part corresponding to the node positioning block 2111 is arranged on the inner side wall surface of the groove structure, and when the clamping part is matched with the clamping of the node positioning block 2111, the parallelism of the tool bit 21 and the tool holder 3 meets the operation requirement. The micrometer 31 is capable of adjusting and measuring the cutting work area 4. When the ultrasonic cutting equipment works, the vibration of the acoustic node position is weakest, and the damping structure is arranged on the node positioning block, so that the vibration and abrasion of the clamping part are within the design tolerance range. The cutter head 21 is provided with a fixing plate 214 which is fixedly connected with the amplitude modulator 212 through a hoop mechanism 215, and a positioning rod 216 is used for installing a hard spring intermediate supporting structure 223 and assisting in determining the installation position of the fixing plate 214; the two sets of support plates 222 are fixedly connected to two ends of the fixing plate 214, respectively, and serve as a bearing structure for supporting the cutter head 21. A connecting piece 224 is arranged in the middle of the frame 221, and in combination with fig. 1, the connecting piece 224 is connected with a servo motor 11 on the frame 1, so that the servo motor 11 can drive the tool bit assembly 2 to move up and down, and the distance between the cutting working areas 4 is adjusted to adapt to materials to be processed with different thicknesses. The guide mechanisms 225 are disposed at two ends of the groove-shaped structure of the frame 221, and are used for limiting the movement of the cutter head assembly 2 in the horizontal direction when the servo motor moves, so as to avoid deviation and influence on the accuracy and effect of ultrasonic cutting.
