  • Patent number: 12539638
    Abstract: A cutting tool includes: a drive device for driving a saw blade to rotate; a base plate having an upper surface and a lower surface, wherein the lower surface is configured to abut against a cut material; a body accommodating at least part of the drive device and connected to the upper surface; a handle at least partially configured behind the body; and a junction portion for detachably mounting a battery set. When a cutting depth of the cutting tool is changed and a cutting angle of the cutting tool remains unchanged, a position of the handle relative to the base plate remains unchanged. The cutting tool is comfortable and convenient to use.
