5. A pipe bending machine according to claim 1, characterized in that, The support device (400) further includes a clamping component capable of clamping or releasing the pipe. The clamping component is connected to the first drive component (410). The clamping component is located directly below the axis of the mounting channel (3221). When the mounting channel (3221) is equipped with a pipe and one end of the pipe extends above the clamping component, the first drive component (410) can drive the clamping component to move upward relative to the body (100) to approach and clamp the pipe.

6. A pipe bending machine according to claim 1, characterized in that, An adjustment device (500) is provided between the body (100) and the bending device (200). The adjustment device (500) includes a first adjustment component (510), which is connected to the body (100). The bending device (200) is connected to the first adjustment component (510), and the first adjustment component (510) can drive the bending device (200) to move relative to the body (100) in the vertical or width direction.

8. A pipe bending machine according to claim 1, characterized in that, The feeding device (300) includes a second drive assembly (310) and an installation assembly (320). The second drive assembly (310) is disposed on the machine body (100) and connected to the installation assembly (320). The installation assembly (320) includes a mounting base (321), a first mounting element (322), a second mounting element (323), a clamping member (324), and a third drive mechanism (325). The mounting base (321) is disposed on the second drive assembly (310) and connected to the first mounting element (322). The installation channel (3221) is located inside the first mounting element (322). The clamping member (324) is movably disposed on one end of the first mounting element (322) near the pipe bending device (200). The second mounting element (323) is sleeved on the first mounting element (322). The third drive mechanism (325) is disposed on the mounting base (321) and connected to the second mounting element (323). When a pipe is installed in the installation channel (3221) and one end of the pipe extends between the feeding device (300) and the pipe bending device (200), the third driving mechanism (325) can drive the second mounting element (323) to move along the length direction closer to the clamping member (324), and the second mounting element (323) can push the clamping member (324) to move radially relative to the installation channel (3221) to approach and clamp the pipe. Alternatively, the third driving mechanism (325) can drive the second mounting element (323) to move along the length direction away from the clamping member (324), and the clamping member (324) releases its clamping of the pipe.

9. A pipe bending machine according to claim 8, characterized in that, The mounting assembly (320) further includes a fourth drive mechanism (326) connected to the first mounting element (322), the fourth drive mechanism (326) being capable of driving the first mounting element (322) to rotate about the axis of the first mounting element (322).

10. A pipe bending machine according to claim 8, characterized in that, A limiting structure is provided between the first mounting element (322) and the second mounting element (323). The limiting structure includes a limiting groove (3233) and a limiting block (3222). One of the limiting groove (3233) and the limiting block (3222) is disposed on the first mounting element (322), and the other is disposed on the second mounting element (323). When the limiting block (3222) is embedded in the limiting groove (3233), the limiting groove (3233) and the limiting block (3222) can cooperate with each other to limit the range of movement of the second mounting element (323) relative to the first mounting element (322) along the length direction.
