High-strength wood cutter

A high-strength wood cutter mainly comprises a working platform arranged on a frame. A motor is mounted on the frame under the working platform, the motor is connected to a cutting and rotating blade through a transmission mechanism, the cutting and rotating blade is vertically disposed on the surface of the working platform or outside one side edge of the working platform, the vertical surface of the cutting and rotating blade is parallel to one side edge of the working platform, at least one half of the cutting and rotating blade is disposed under the surface of the working platform, a central rotating shaft of the cutting and rotating blade is supported on the frame under the working platform through bearings at two ends, and one end of the rotating shaft is connected with the transmission mechanism; a positioning strip which is parallel to the vertical surface of the cutting and rotating blade and can be adjusted in distance relative to the cutting and rotating blade is arranged on the working platform on the other side relative to the cutting and rotating blade. The high-strength wood cutter has the advantages of simple structure, convenience and reliability in use, applicability to cutting of high-strength wood different in size and varied in shape, high-precision cutting effect and the like.
