The second and fourth telescopic rods are extended, allowing the clamping plate and the clamping wheel to clamp the tube to be flattened on the flattening wheel. At this time, the hydraulic motor rotates to drive the worm gear, which engages with the turbine to rotate the flattening wheel. Simultaneously, the third telescopic rod extends to drive the clamping plate to move along the length of the tube until a certain angle of flattening is achieved.
