Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs. 1-2, a kind of screwdriver of detachable cutter head, including holding rod A1, holding rod B12 and fixed block 4, institute
It states the upper ends holding rod A1 and fixed block 4 is installed, 4 inner upper end of the fixed block is equipped with headlamp 6, the lower ends the holding rod A1
Threaded hole 13 is offered, the threaded hole 13 of the lower ends the holding rod A1 is rotated with the spiral lamination 11 mounted on the upper ends holding rod B12
Connection, the holding rod A1 upper end faces left and right sides offer sliding slot 3, are mounted at left and right sides of 3 upper end of the sliding slot
Fixture block 7 is equipped with sliding ball 8 between two groups of 7 surfaces of fixture block, and 8 lower end of the sliding ball is fixedly connected with sliding bar 9, the sliding
9 lower end of bar is fixedly connected with the upper ends driver bit A10, and card slot is offered at left and right sides of the holding rod B12 inner surfaces lower end
The card slot 18 of the lower end 18, the holding rod B12 and 16 inlay card of buckle at left and right sides of 15 outer surface of mounting blocks.
Wherein, the holding rod A1 interior lower ends are equipped with retainer plate 14, the 14 inside left and right sides of the retainer plate with
Two groups of 2 lower end inlay card connections of spring.
Wherein, the spring 2 is placed in the upper ends driver bit A10 outer surface, and the diameter of spring 2 is less than 9 lower end of sliding bar
Diameter, spring 2 is compressed so that driver bit A10 moves out the bottom ends holding rod B12.
