The collection box 194 can only move horizontally under the limit of the insertion rod 23. At this time, the spring 24 on one side of the collection box 194 is compressed, and the spring 24 on the other side is stretched. When the half-face gear 21 rotates to a certain angle, the teeth on the half-face gear 21 and the tooth plate 22 are disengaged. At this time, the compressed spring 24 releases the elastic force, and the stretched spring 24 is reset, driving the collection box 194 to move to the other side, and so on and so forth, so that the collection box 194 moves back and forth.
