The utility model content

The utility model purpose is to provide a kind of straight screwdriver of can working as to use the screwdriver that can work as the Phillips screwdriver use for the deficiency that overcomes prior art.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of screwdriver, comprise a knife bar and a word cutter head, and a said word cutter head is arranged on the knife bar lower end, and symmetry has chute in the said knife bar; The median plane of the median plane of said chute and a word cutter head is perpendicular; The surface of said chute and a word cutter head near; Be provided with the slide block that can in chute, slide in the said chute.

Preferably, be arranged with groove on the said knife bar; Said groove communicates with chute; Have locating hole and following locating hole in the said knife bar; The said locating hole of going up communicates with chute with following locating hole; Have pin hole on the said slide block; Be provided with latch in the said pin hole; After said upward locating hole and the pin hole alignment, insert latch, the lower surface of said slide block and knife bar lower surface flush; After said locating hole down and the pin hole alignment, insert latch, the lower surface of said slide block and a word cutter head lower surface flush.

Preferably, said slide block the inner has counterbore; Said counterbore is concentric with pin hole; Said counterbore is identical with the aperture of last locating hole and following locating hole.

Preferably, said latch is made up of first cylinder, second cylinder and three cylindrical; The diameter of said first cylinder is identical with counterbore; The diameter of said second cylinder is identical with the aperture of pin hole; The diameter of said three cylindrical is identical with the width of groove.

Preferably, the said first cylinder jacket rubber sleeve.

Preferably, said three cylindrical stretches out outside the knife bar.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

The screwdriver of the utility model; Because symmetry has chute in the knife bar, the median plane of the median plane of chute and a word cutter head is perpendicular, the surface of chute and a word cutter head near; Be provided with the slide block that can in chute, slide in the chute; When using at ordinary times, slide block is positioned at chute, when straight screwdriver uses; Slide chute, just can work as Phillips screwdriver and use, it is extremely convenient to use, and has solved the problem of existing screwdriver function singleness.
