The tops of the two connecting blocks 23 are rotatably connected to the connecting rod 22. A fixed block 21 is fixedly installed at the center of the bottom end of the lifting block 19, and the tops of the two connecting rods 22 are rotatably connected to the two sides of the bottom end of the fixed block 21. Electric hydraulic cylinders 3 are fixedly installed on both sides of the support block 2, and the telescopic ends of the two electric hydraulic cylinders 3 extend to the inside of the strip groove 20 and are fixedly connected to the side of the connecting block 23.

[0018] Specifically, the height of the loading seat 4 can be adjusted by the lifting assembly, which can adapt to loading under different height conditions.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a feeding mechanism of a straightening machine, the transmission mechanism includes a sprocket 15, a chain 17 and a driving motor 14, the bottoms of multiple connecting shafts 16 are fixedly installed with sprockets 15, the chains 17 are transmission-connected between the multiple sprockets 15 on the same side, the driving motor 14 is fixedly installed inside the U-shaped frame 13, and the output shaft of the driving motor 14 is fixedly connected to the bottom end of the corresponding connecting shaft 16 through a coupling.
