[0019] like Figure 1 and Figure 3 As shown, the extrusion assembly includes a fixed plate 9, a second fixed column 10, a second sliding disk 101, a second connecting frame 11, a second screw rod 12 and a tray 13. The fixed plate 9 is threadedly connected to the screw rod 3, and the fixed plate 9 is slidably connected to the workbench 1.

[0020] At first, the baffle 17 is away from the first fixed column 5.

The bending degree of the steel bar can be adjusted according to the moving distance of the fixed plate 9.
