A fixing hole 702 for plugging and matching with the front end of the drill bit 101 is provided at the end of the screwdriver bit main body 7.

[0033] Specifically as Figure 3As shown in Figure 4 Figure 4 At the end of the screwdriver bit body 7 where the fixing hole 702 is provided, a rotating ring 703 is sleeved. The rotating ring 703 is movably placed inside the mounting cylinder 6, so that the screwdriver bit body 7 can be rotated and mounted on the mounting cylinder 6. In addition, the drill bit 101 has a hexagonal structure, and the fixing hole 702 is a hexagonal groove adapted thereto. At the same time, a screw head 701 is constructed at one end of the screwdriver bit body 7 away from the fixing hole 702, and the screw heads 701 at the ends of each screwdriver bit body 7 are different, so as to be used for screwing different types of screws and bolts.

[0034] The working principle provided by the present utility model for the combined screwdriver bit applicable to an electric screwdriver is as follows. When in use, the fixing ring 2 can be threadedly mounted at the end of the electric screwdriver 1, and thus the movable ring 3 is also sleeved at the end of the electric screwdriver 1. Therefore, when it is necessary to select different screwdriver bit bodies 7, the required screwdriver bit body 7 can be rotated to the port of the movable ring 3 by rotating the rotating frame 5, and the elastic connection between the fixing ring 2 and the movable ring 3 is utilized to enable the drill bit 101 on the electric screwdriver 1 to be inserted into the corresponding screwdriver bit body 7 to complete the installation.

[0035] In summary, the present device can conveniently and flexibly replace different screwdriver bit bodies 7 at the end of the electric screwdriver 1 for use, without the need to carry a large number of screwdriver bits, and is convenient to use.
