[0006] A sleeve shaft is rotatably sleeved on the connecting shaft, and a driving disk is fixedly sleeved on the sleeve shaft. A spiral groove is provided on the driving disk, and a protrusion fixed on the upper side of the sliding seat slides along the spiral groove.

[0007] Preferred technical solution 1: A differential gear set is connected between the sleeve shaft and the connecting shaft, and the differential gear set realizes differential rotation between the sleeve shaft and the connecting shaft through meshing transmission.

[0008] Preferred technical solution 2: A motor is installed on the top frame, and the output shaft of the motor is fixedly connected to the connecting shaft.

[0009] Optimal technical solution three: a column is fixed at the center of the base.

[0011] Preferred technical solution five: The column is screwed into the threaded hole opened at the center of the base through the threaded section at the bottom end, so that the column can be disassembled, so that the column of the corresponding diameter can be replaced when processing spirally wound heating tubes with different inner diameters.

[0012] The above structure enables this solution to have the following beneficial effects:

[0013] 1. A set of power sources can be used to drive the connecting shaft and the driving disk to rotate at a differential speed, thereby realizing the planar spiral winding of the heating disk;
