Method of manufacturing metal basket

A method of manufacturing a metal basket comprising:

• a step of preparing materials, wherein multiple first metal bars, multiple second metal bars, four connection pieces, and at least two peripheral bars are provided;
• a step of initial welding, wherein the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together to produce a grid frame which has a base, wherein when the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together, the at least two peripheral bars are welded with the base, wherein each of the at least two peripheral bars has two bending extensions extending from two ends of each peripheral bar, and wherein the four connection pieces are welded on the two bending extensions of each peripheral bar;
• in a step of bending, wherein the grid frame is bent, such that part of the multiple first and second metal bars is bent upwardly and are perpendicular to the base to form a body with an opening facing upwardly, wherein the two bending extensions are connected together to produce a holder, and wherein the four connection pieces and the two bending extensions of each peripheral bar are bent so that any two adjacent of the four connection pieces has a cutout defined therebetween and form each of two movable connectors;
• and
• in a step of finish welding, wherein the two bending extensions of each peripheral bar of the holder are welded together, and wherein the cutout between any two adjacent connection pieces is welded to connect the any two adjacent connection pieces together.
