The limiting groove 18 serves to limit the elastic band. Then, the drive motor 8 can be started, so that the output shaft of the drive motor 8 drives the rotating rod 5 to rotate, thereby causing the mounting rod to rotate, thus causing the mounting rod to cut the elastic band. The elastic band is fed between the cutting seat 3 and the cutting blade 19. Then, the servo motor 11 is started, causing the output shaft of the servo motor 11 to drive the bidirectional lead screw 15 to rotate. Under the action of the two oppositely oriented thread grooves on the bidirectional lead screw 15, the two slide bars 4 are brought closer to each other. Under the action of the cutting blade 19 and the cutting seat 3, the elastic band is cut. The buffer spring acts as a buffer to prevent damage to the cutting blade 19. Then, the elastic band falls under the action of gravity, which then activates the drive motor 8 to continue feeding and cutting.
