An electric telescopic rod is arranged inside the transverse guide rail 23. The electric telescopic rod is used to drive the cutting motor and the cutting blade 24 to slide. The cutting motor is slidably connected inside the transverse guide rail 23. The cutting motor is a three-phase asynchronous motor. The cutting motor is connected to an external circuit through an electric wire. One end of the output shaft of the cutting motor is fixedly connected with The cutting blade 24 drives the screw rod 33 to rotate by starting the feeding motor 31. The rotation of the screw rod 33 causes the movable plate 34 to slide on the surface of the limit rod 32.
