One end of the forming main part 1 is processed with a groove platform 7, and a clamping concave block and an adjusting positioning top block 4 are welded on the forming main part 1; one end of the adjusting positioning top block 4 is provided with an adjusting tightening bolt 5, and the adjusting tightening bolt 5 is arranged above the clamping concave block. The adjusting tightening bolt 5 is used to adjust the clamping concave block, and the clamping concave block is used to clamp the copper tube assembly 6; the forming main part 1 is clamped on the slow turntable. Specifically, the forming main part 1 is cylindrical, including three parts with different coil diameters. The middle part is a groove platform 7 processed on the forming main part 1, and a clamping concave block is welded on the groove platform 7 to clamp the copper tube assembly 6; the adjusting tightening bolt 5 is arranged 0.5 mm above the clamping concave block and is used to adjust and press against the clamping concave block to clamp the copper tube assembly 6; the adjusting tightening bolt 5 is arranged on the adjusting positioning top block 4, and the adjusting positioning top block 4 is in an inverted "L" shape and is used to fix the adjusting tightening bolt 5.

[0018] In this embodiment, the clamping concave block includes a zero-point clamping concave block 2 and an adjusting clamping concave block 3. The adjusting clamping concave block 3 is in movable contact with the adjusting tightening bolt 5, and the zero-point clamping concave block 2 is welded to the groove platform 7. Specifically, the clamping surfaces of the zero-point clamping concave block 2 and the adjusting clamping concave block 3 are cylindrical, and the specific diameter size can be determined according to the copper tube assembly 6 to be coiled as required. When coiling, only need to place the copper tube assembly 6 on the zero-point clamping concave block 2, clamp it with the adjusting clamping concave block 3, and then tighten the adjusting tightening bolt 5 installed on the forming main part 1 to abut against the adjusting clamping concave block 3 to clamp the copper tube assembly 6.
