The assembled stirring unit includes an assembled piece and a stirring blade, wherein a length direction of the assembled piece is an axial direction, a direction perpendicular to the axial direction is a radial direction, and the assembled piece has a first joining piece and a second joining piece respectively at two ends thereof in the axial direction. The stirring blade is provided on the assembled piece and extends towards the radial direction, and the stirring blade is twisted at an angle by having the radial direction as an axis. The stirring rod is formed by serially connecting multiple assembled stirring units along the axial direction. ## Claims ### Claim 1 An assembled stirring unit of a stirring rod of hot and cold foods supplying machine, comprising: an assembled piece, a length direction of the assembled piece being an axial direction and a direction perpendicular to the axial direction being a radial direction, the assembled piece extending between first and second axially-opposed end portions, wherein an insert block is disposed at the first end portion of the assembled piece and extends axially away therefrom, and wherein an insert slot is formed in the second end portion of the assembled piece; and a stirring blade provided on the assembled piece and extending towards the radial direction, wherein the stirring blade is a 60-degree arc-shaped plate twisted at an angle of 60 degrees by having the radial direction as an axis. ### Claim 2 A stirring rod of hot and cold foods supplying machine, comprising multiple assembled stirring units serially connected and assembled along an axial direction, each of the assembled stirring units includes: an assembled piece, a length direction of the assembled piece being the axial direction and a direction perpendicular to the axial direction being a radial direction, and the assembled piece extending between first and second axially-opposed end portions, wherein an insert block is disposed at the first end portion of the assembled piece and extends axially away therefrom, and wherein an insert slot is formed in the second end portion of the assembled piece; and a stirring blade provided on the assembled piece and extending towards the radial direction, wherein the stirring blade is twisted at an angle by having the radial direction as an axis; wherein respective assembled pieces of adjacent corresponding assembled stirring units are connected one to another and devoid of threaded fasteners, the insert block of one assembled piece being received within the insert slot of a corresponding adjacent assembled piece; wherein the stirring blades of the multiple assembled stirring units collectively form a spiral blade along the axial direction and the spiral blade has at least one notch, and lateral sides of the stirring blades of adjacent assembled stirring units are not joined adjacently, thereby forming the notch therebetween; and wherein each of the stirring blades is a 60-degree arc-shaped plate having a twist angle of 60 degrees. ### Claim 3 (depends on 2) The stirring rod of claim 2, wherein an assembly rod penetratingly extends through the assembled piece of each of the assembled stirring units so as to serially connect each of the assembled stirring units. ### Claim 4 (depends on 3) The stirring rod of claim 3, wherein an outer surface of the assembly rod and inner surfaces of the assembled pieces, along the axial direction, both have non-circular cross sections. ### Claim 5 (depends on 2) The stirring rod of claim 2, wherein a base is serially connected to the assembled stirring unit located at a position adjacent to one end portion of the stirring rod. ### Claim 6 A stirring rod of hot and cold foods supplying machine, comprising multiple assembled stirring units serially connected and assembled along an axial direction, each of the assembled stirring units includes: an assembled piece, a length direction of the assembled piece being the axial direction and a direction perpendicular to the axial direction being a radial direction, and the assembled piece extending between first and second axially-opposed end portions, wherein an insert block is disposed at the first end portion of the assembled piece and extends axially away therefrom, and wherein an insert slot is formed in the second end portion of the assembled piece; and a stirring blade provided on the assembled piece and extending towards the radial direction, wherein the stirring blade is twisted at an angle by having the radial direction as an axis; wherein respective assembled pieces of adjacent corresponding assembled stirring units are connected one to another and devoid of threaded fasteners, the insert block of one assembled piece being received within the insert slot of a corresponding adjacent assembled piece; wherein the stirring blades of the multiple assembled stirring units collectively form a spiral blade along the axial direction and the spiral blade has at least one notch, and lateral sides of the stirring blades of adjacent assembled stirring units are not joined adjacently, thereby forming the notch therebetween; and wherein the stirring blades of the assembled stirring units include at least one 60-degree arc-shaped plate having a twist angle of 60 degrees and at least one 300-degree arc-shaped plate having a twist angle of 30 degrees, wherein the stirring blades of different degrees and twist angles are arranged alternately. ### Claim 7 (depends on 6) The stirring rod of claim 6, wherein an assembly rod penetratingly extends through the assembled piece of each of the assembled stirring units so as to serially connect each of the assembled stirring units. ### Claim 8 (depends on 7) The stirring rod of claim 7, wherein an outer surface of the assembly rod and inner surfaces of the assembled pieces, along the axial direction, both have non-circular cross sections. ### Claim 9 (depends on 6) The stirring rod of claim 6, wherein a base is serially connected to the assembled stirring unit located at a position adjacent to one end portion of the stirring rod.
