Detailed description of the invention

By further illustrating the technological means and effect that this utility model taked by realizing predetermined utility model purpose, below fasten accompanying drawing and preferred embodiment, to according to detailed description of the invention of the present utility model, structure, feature and effect thereof, describe in detail as after.

The overall structure schematic diagram of the screwdriver that Fig. 1 provides for one embodiment of this utility model.A kind of screwdriver that the present embodiment provides, including multiplex cutter head 1, rotation section 2, puts cutter head shell 3, handle of a knife 4 and handle of a knife shell 5；Described multiplex cutter head 1 links together with rotation section 2, described rotation section 2 be connected to described in put between cutter head shell 3 and handle of a knife shell 5；Described handle of a knife 4 is placed in described handle of a knife shell 5；Arranging handle of a knife slider 41 on described handle of a knife 4, described handle of a knife shell 5 arranges chute 51, described handle of a knife slider 41 is emerging in the outer surface of described handle of a knife shell 5 by described chute 51；Described one end away from described rotation section 2 putting cutter head shell 3 arranges out the edge of a knife 32.

In detail, multiplex cutter head 1 includes the sub-cutter head of at least two.Figure shows sub-cutter head 11, sub-cutter head 12.It is appreciated that user can be arranged as required to into three, four sub-cutter heads or more.

Further, cutter head slider 6 is also included；Being respectively provided with installing hole on every sub-cutter head 11,12 of described multiplex cutter head 1, described cutter head slider 6 is detachably arranged in described installing hole.In detail, through hole 31 is offered on cutter head shell 3 putting.During use, rotating sub-cutter head to be used to through hole 31 position, sub-cutter head the most to be used is corresponding with going out the edge of a knife 32 position；Again cutter head slider 6 is arranged on the installing hole of sub-cutter head through through hole 31；Being prevented when connecting handle of a knife 4 with sub-cutter head to be used by cutter head slider 6, sub-cutter head to be used is pushed out.In detail, after handle of a knife 4 and sub-cutter head to be used are installed, cutter head slider 6 is dismantled, releases sub-cutter head to be used with handle of a knife slider 41.

Further, described handle of a knife 4 one end arranges the connecting portion 42 with described multiplex cutter head, and the sub-cutter head of multiplex cutter head 1 is connected one end with handle of a knife 4 and arranges screens hole；The shape of described connecting portion 42 port is corresponding with described screens hole shape；During use, described handle of a knife 4 is inserted in the screens hole of corresponding sub-cutter head, rotate described handle of a knife 4 and realize the installation of handle of a knife 4 and sub-cutter head.In an example, being shaped as of the screens hole of sub-cutter head is cross, and the connecting portion 42 of handle of a knife 4 is cross projection, after being inserted by handle of a knife 4, rotating handle of a knife 4 can make connecting portion 42 stagger for the screens hole of cross protruding and sub-cutter head, it is achieved the engaging of handle of a knife 4 and sub-cutter head.

Further, described chute 51 is " Z " or " Contraband " type.In figure as a example by " Contraband " type.In detail, when handle of a knife 4 being inserted in sub-cutter head to be used, rotate handle of a knife slider 41 and realize rotating handle of a knife 4, thus realize snapping in sub-cutter head handle of a knife 4；The sub-cutter head realized band use that slides then along chute 51 releases out the edge of a knife 32；After releasing sub-cutter head, being rotated along chute 51 again by handle of a knife slider 41, it is achieved limited handle of a knife 4 position, when preventing from using, sub-cutter head or handle of a knife slide in putting cutter head shell 3 or handle of a knife shell 5；When making user use screwdriver, screwdriver is more stable.

The above, it it is only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, although this utility model discloses as above with preferred embodiment, but it is not limited to this utility model, any those skilled in the art, in the range of without departing from technical solutions of the utility model, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solutions of the utility model content, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, all still fall within the range of technical solutions of the utility model.
