The invention discloses an anti-winding unmanned ship with a carbon fiber cutting tool, which relates to the technical field of the unmanned ship and comprises an unmanned ship body, wherein an uppersurface of the unmanned ship body is fixedly installed with a telescoping mechanism, the left end of the telescoping mechanism is fixedly installed with a rotating mechanism, and a bottom surface of the rotating mechanism is fixedly connected with a cutting mechanism. By arranging a rotating mechanism, the device can be rotated to precisely adjust that angle of the device to align the winding object, by arranging the cutting mechanism, the ship can adjust the position of the cutting knife and the winding object to cut, a support plate and a second threaded pipe are arranged, and a slide rod, aslide groove, a bottom plate, a slide block and a slide ring are cooperated to support that screw rod along with the movement of the screw rod, thereby avoiding the problem of inclination of the screw rod and improving the stability and safety of the device.
