When the cutter mechanism 1331 is needed to work, the rotating part is rotated to drive the first gear to rotate, and then the gear column is rotated. The rotation of the gear column drives the dragging part to rise, and lifts the cutting part, and the cutter part moves out of the third storage groove 133a for shearing operation; when the cutter mechanism 1331 is stored, the rotating part is returned to its position. It should be noted that the gear set described in the present invention is not limited to the first gear and the gear column mentioned above. According to needs, the rotating part can also be directly connected to the gear column to drive the dragging part to rise and fall, or more gears can be set between the first gear and the gear column, which will not be repeated here.
