Abstract

The utility model discloses a multifunctional screw driver which comprises a gripping handle, a toolbar and tool bits. The multifunctional screw driver is characterized in that the toolbar is formed by a first section, a second section and a third section. The second section is arranged in the middle of the first section and the third section. Cross sections of the first section and the third section are squares, and cross sectional areas of the first section and the third section are same. The head end of the first section and the head end of the third section are respectively connected with the tool bit. The two tool bits are respectively a cross-shaped tool bit and a line-shaped too bit. The width of the second section is larger than the width of the first section and the width of the third section. Four hexagonal trepan borings corresponding to hexagon nuts with different specifications are formed in the second section. The gripping handle is cylindrical. The front end of the gripping handle is provided with an inserting hole of the first section or an inserting hole of the third section, wherein the inserting hole is used for inserting the toolbar in the axial direction. A cross section of the inserting hole is a square.
