Zusammenfassung:The utility model relates to a special-shaped multipurpose screwdriver, which comprises a screwdriver bit (1) and a handle (2) and is characterized in that the middle of the handle (2) is provided with a hole, and the screwdriver bit (1) penetrates through the hole to be fixed onto the handle (2) through a bolt (3). A stress rod (4) is arranged at the other end of the handle (2) and connected with the handle (2) in an inserted manner. The special-shaped multipurpose screwdriver has the advantages that the screwdriver is applicable to operation in a space with the area of 10cm2, especially portions in narrow spaces where normal screwdrivers cannot be operated, and different conical heads can be replaced for the screwdriver to meet the operation requirements. Further, the screwdriver is especially applicable to secondary wiring of mutual inductors.
