According to another embodiment of the present invention, it may also be a composite, *,, shaped screwdriver, , '. The structure 'this%' includes six first-abutting top faces, six second abutting top faces, and six working grooves, and the tapered portion is in the shape of a, *, shape. According to the above description, the creation uses the Yi Ding nickname and the w working part to make the working part with smaller size when the lock is small (4): work, and the size when using the larger screw The larger working part can be locked and unloaded. It is not necessary to operate the screwdriver head of two generations - ^ size. It can be used early - the screwdriver can be used to enter the ^ & And therefore, 'Bai Zhizhong caused damage due to the size difference of the screwdriver head, and then moved, and took the service life of the screw groove of the company. Therefore, the "have industry" and "utility" of this creation should be unquestionable. In addition, the extra strength revealed in this book is in the yoke of the yoke, and it has not been publicized before the application.
