The present invention relates to a method for automatically adjusting the screwing speed of a screwdriver in several successive steps. The method is characterized by comprising executing at least two continuous grades, wherein a preset point speed Vc is kept constantly in the period of each grade and is adjusted from one grade to the next grade. Furthermore the preset point speed is calculated for satisfying an equation: Vc=VMax*K1*K2, wherein K1 is a constant coefficient of the variation range of torque that varies along with time. Furthermore K2 is a constant coefficient which aims at the percentage range of the final torque. Furthermore each grade is predefined by an upper limit and a lower limit that are represented by the percentage form of the final torque. Furthermore the variation from one grade to the next grade causes value variation of the coefficient K2.
