[0029] In this embodiment, the chuck 41 of the cutter assembly 4 is fixedly connected to the sonic motor 31 of the sonic drive assembly 3. Specifically, one end of the chuck 41 can be detachably connected to the sonic motor 31 by bolts or buckles; when the sonic motor 31 is working, it drives the tool on the chuck 41 to rotate. The sonic drive assembly 3 and the inner bracket 2 can be fixedly connected by bolts to facilitate disassembly and maintenance. The charging interface 11 is electrically connected to the rechargeable battery 33 and the control circuit board 32, so that the control circuit board 32 controls the charging interface 11 to charge the rechargeable battery 33. The rechargeable battery 33 is also electrically connected to the control circuit board 32 to supply power to the control circuit board 32, and the control circuit board 32 is electrically connected to the sonic motor 31 to control the power supply, power supply current or power supply voltage of the rechargeable battery to the sonic motor 31.

[0030] The sonic cutting tool of this embodiment has a built-in rechargeable battery 33 that can be powered by direct current. The product is small, easy to carry and easy to operate. The sonic motor 31 is used to provide sonic power to improve cutting accuracy and efficiency. The locking component 43 can meet the needs of replacing tools of different specifications, and the detachable connection between the chuck 41 and the sonic motor 31 can meet the needs of replacing the chuck 41 required for different scenarios, thereby enriching the use scenarios of the cutting tool.

[0031] Optionally, the charging interface 11 is a magnetic charging interface, which is located in the bottom cover of the outer shell 1 and can be fixedly connected to the bottom cover by bolts, and fixed and re-welded on the control circuit board 32 by PCB to reduce attenuation caused by high temperature. This optional embodiment uses a magnetic charging interface to meet the waterproof requirement.

[0035] In this embodiment, the locking nut 432 is located at the bottom of the chuck 41 in an unlocked state. When the locking nut 432 moves toward the top of the chuck 41, the chuck 41 is tightened inwardly due to the inverted triangle of the chuck 41, and thus the tool in the tool clamping groove 411 is clamped. When the locking nut 432 moves toward the bottom of the chuck 41, the external force on the chuck 41 is reduced, and the tool in the tool clamping groove 411 is loosened, so that the tool can be removed for replacement, meeting the requirements of different tool specifications in different scenarios.

[0036] Optionally, the tool clamping groove 411 is in the shape of a straight line or a cross to meet the requirements of tool specifications in different scenarios. It is understandable that the tool clamping groove 411 is a groove with three sides open, and when the locking sleeve 431 is tightened, the two groove sides of the tool clamping groove 411 are relatively close to each other and clamped.

[0037] See also Figure 6 In some embodiments, one end of the chuck 41 is locked to the main shaft of the sonic motor 31 by a countersunk screw 34. One end of the chuck 41 and the main shaft of the sonic motor 31 are both provided with interconnected screw holes.
