BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a torque adjusting driver capable of limiting a torque of a driver to a predetermined torque, and more particularly, The present invention relates to a multi-step torque adjusting driver capable of adjusting a rotational force required for each operation using a driver in a plurality of stages more quickly, The multi-step torque adjusting driver according to the present invention comprises: a tip holder rotating shaft 10 having a predetermined depth of a tool tip inserting groove 11 to which a tool tip 2 is detachably inserted； A plurality of first ball receiving grooves 21 are formed at a predetermined depth in a radial direction along the circumference of the rear side of the tip holder rotational shaft 10, A torque transmission bearing (20) on which the first slip ball (22) is seated； A plurality of second ball receiving grooves 31 are formed at a predetermined depth in a radial direction along the circumference of the front side surface of the tip holder rotation shaft 10, An over-torque slip bearing 30 in which a second slip ball 32 is seated in each of the second ball seating grooves 31 and a one-way clutch front insertion groove 33 of a predetermined depth is provided at the rear； The tip holder rotation shaft 10 passes through the inner hollow and is located at the rear of the over torque slip bearing. The front portion is inserted into the one-way clutch front insertion groove 33 of the over torque slip bearing 30, A one-way clutch (40) provided on a side face of the one-way clutch front insertion groove (33) so as to be in close contact with the inner peripheral surface of the one-way clutch front insertion groove (33)； Way clutch rearward insertion groove 51 is provided at a front portion of the one-way clutch rear insertion groove 51. A rear portion of the one-way clutch 40 is inserted into the rearward insertion groove 51 of the one- The outer surface of the on
