Description

[0034] like Figure 1-3 As shown, in this embodiment, the first assembly line 1 and the second assembly line 2 cooperate to transport and store materials, and the third assembly line 3 and the fourth assembly line 4 cooperate to transport and store materials.

The third groove 27-1 is a square groove with two ends through. This arrangement allows the first stopper 16 and the second stopper 17 to slide in the third groove 27-1 to change the distance between the first assembly line 1 and the second assembly line 2 to adapt to bars of different lengths. The connection method of the third gear 25, the fourth gear 26 and the second connecting rod 28 is the same as above and will not be repeated here.
