Description
Technical field
The utility model relates to a kind of daily life and uses hand-operated tools, and more particularly, the utility model relates to a kind of screwdriver.
Background technology
Screwdriver is to be used for the hand-operated tools fastening or screw that comes loose, at present, and screwdriver of a great variety; Function also becomes more diverse, and common multipotency screwdriver, its handle and screwdriver rod all are discrete; The shared handle of a plurality of screwdriver rods, the screwdriver of use difference in functionality needs the different knife bar of adapted; Its structure more complicated, handle and knife bar are not integral.
Like the Chinese patent publication number is CN2309207; Open day is the patent application case of 1999-03-03; A kind of dual intensity screwdriver is disclosed; Its structure comprises that screwdriver rod and the screwdriver handle of processing straight screwdriver head and Philip's head screw cutter head respectively by two ends constitute, and the degree of tightness through the handle upper knob can make screwdriver rod and screwdriver handle separately or be fixed together, and the Lian Duanke of transposing screwdriver rod obtains straight screwdriver or Phillips screwdriver.This screwdriver combines straight screwdriver and Phillips screwdriver, though made things convenient for user's use, has practiced thrift production cost; But in practical application, also come with some shortcomings; Its screwdriver rod is connected through knob with screwdriver handle, and defective tightness and firm is fastening or come loose some when connecting more closely screw; Need the very big fastening or screw that comes loose of power ability of expense, even the danger that damages screw driver handle is arranged.
The utility model content
The purpose of the utility model is to overcome the deficiency that complicated, a plurality of knife bar of prior art multipotency screwdriver structure is discrete, operation is required great effort, handle damages easily, provides a kind of a plurality of knife bar to be concatenated into one, uses screwdriver laborsaving, fragile, not simple to operate.
In order to address the above problem; The utility model takes following proposal to be achieved: a kind of screwdriver is provided, comprises handle and the knife bar that is fixedly connected with handle, said knife bar removably is connected in series by some knife bars unit and constitutes; Each knife bar unit is made up of the head segment of an end and the linkage section of the other end; The side of said head segment has a plane at least, and the end face of said linkage section is provided with the counterbore adaptive with head segment, and said handle end face is provided with the connecting rod adaptive with counterbore.In the utility model, the side of said head segment has a plane at least, and purpose is to form moment of torsion; Be easy to rotate; Just can become screwdriver, certainly be designed to hexagon, square or triangle, but can not be designed to circle; Can not form moment of torsion because be designed to circle, nature can not become screwdriver; Some knife bars unit independent design of the utility model, mutual dismountable one that is concatenated into, being connected with handle more promptly becomes screwdriver, simple in structure, easy to use.
As a kind of preferred version of such scheme, said handle is cylindrical, and its outer surface upper edge is axially arranged with anti-slip tank.On the cylindrical handle outer surface, axially design anti-slip tank, can be anti-skidding during use.
As a kind of preferred version of such scheme, described handle is provided with horizontal through hole.Like this, can pass through hole with a Metallic rod during use and rotate then, will be laborsaving during fastening or loosening screw.
As a kind of preferred version of such scheme, said knife bar unit adopts magnetic material to process.Like this, handle of a knife, cutter head just are not easy to be scattered, and a plurality of knife bars unit closely connects.
The beneficial effect of the utility model is:
1. many knife bars are concatenated into one, and are simple in structure, increased the length of screwdriver rod virtually.
2. use laborsaving, not fragile.
3. simple, convenient.
