The invention discloses a cutting device for processing of new materials. The cutting device comprises a base and a box body, first electric retractable rods are fixedly connected to the two sides ofthe top of the base respectively, the tops of the first electric retractable rods are fixedly connected to the bottom of the box body, through holes are formed in the two sides of the top of the baserespectively, a long hole is formed in the bottom of the box body, and a forward-backward motor is fixedly connected to the bottom of an inner cavity of the base through a fixing block. Through the cooperation among the base, the box body, the first electric retractable rods, the through holes, the long hole, the forward-backward motor, a forward-backward threaded rod, first threaded sleeves, casing pipes, third electric retractable rods, clamping plates, a first motor, a threaded rod, a second threaded sleeve, a support plate, a second motor and a cutter for use, the problems are solved thatexisting cutting devices are monotonous in structure, the new materials cannot be clamped, the cutting height cannot be adjusted, the cutting devices are very limited during use, and the practicalityof the cutting devices is reduced.
