[0022] Example 1:

[0023] like Figure 1 As shown in Figure 3, a forklift jack 25 includes two side frames 1. Each side frame 1 is equipped with a drive unit and a lifting unit 2. The lifting unit 2 includes a drive shaft 21 and a driven shaft 24. The drive shaft 21 and the driven shaft 24 are rotatably connected to the bottom and top of the side frame 1, respectively. Both the drive shaft 21 and the driven shaft 24 are fitted with sprockets 22. The two sprockets 22 are connected by a chain 23. The chain 23 fixes a lifting frame 25. The lifting frame 25 is equipped with a support plate 26 for supporting a pallet 4. The side frame 1 is equipped with a guide rod 27, which is vertically arranged. The lifting frame 25 passes through the guide rod 27.

[0024] The forklift 25 in this embodiment uses a lifting unit 2, which can quickly lift and lower the support plate 26, thereby enabling the pallets 4 to be quickly stacked on the conveyor line. In addition, in conjunction with the roller conveyor belt 3, it can assist the pallets 4 to be stacked off the support plate 26, resulting in a high degree of automation.
