An annealing and drawing device for an oxygen-free copper tube used for a mobile phone heat pipe with a large diameter-wall thickness ratio, a drawing die is installed in a box body. An annealing tube is installed between the drawing die and the box body; a fixing plate is disposed on a side of the drawing die; a supporting roller is rotatably connected to the fixing plate. A tension adjusting mechanism is disposed on a side of the supporting roller. An outer side of an end of the box body is provided with a mounting plate. A supporting frame is fixed on a side of an upper end of the mounting plate, a servo motor is fixed at an upper end of the supporting frame, and a rotating shaft is fixed at an end of an output shaft of the servo motor. The rotating shaft is in key joint with a winding wheel.
