More specifically, the first conveyor 1 has an expanded state (as shown in fig. 3) and a compressed state (as shown in fig. 4), the first conveyor 1 is alternately changed between the expanded state and the compressed state, so that the width of the first conveying passage 13 in the transverse direction is alternately changed between a first width and a second width, namely, the first conveyor 1 is in the expanded state as shown in fig. 3, the width of the first conveying passage 13 in the transverse direction is a first width, and the first width is greater than or equal to the axial length of the spring 300, so that the spring 300 is received in the first conveying passage 13, namely, the spring 300 is received in the first conveyor 1 by the first conveyor 1; the first conveyor 1 is in a compressed state as shown in fig. 4, and the width of the first conveying passage 13 in the lateral direction is a second width that is smaller than the axial length of the spring 300, so that the spring 300 is compressed by the first conveyor 1 by a predetermined amount and conveyed, i.e., the first conveyor 1 compresses the spring 300 by a predetermined amount and conveys the compressed spring 300 to the second conveyor 2.
It will be appreciated that the spring 300 is gradually compressed as the first conveyor 1 changes from the expanded state to the compressed state, and the spring is compressed to a predetermined amount in the compressed state. Further, the first conveyor 1 may also receive at least two sets of springs 300 at a time, and the springs 300 within the set of springs 300 received at a time are simultaneously compressed and conveyed to the second conveyor 2 one by one while receiving the set of springs 300.
