Description

Convertible double-threaded screw cutter

Technical field

The utility model relates to a kind of screwdriver, particularly a kind of especially can be by the upset of fixed axis, change fast 1-shaped open and cross mouth cutter head, can fastening loosening 1-shaped open and the upset pressure double-threaded screw cutter of cross mouth screw.

Background technology

The screw driver handle on the market and the design of cutter are divided into two kinds, and a kind of is integral type, and handle and tool heads are integrated, and the characteristics of integral type are: easy to use, but function singleness.

Another is a combined type, one piece of tool heads of a handle combination, to from the tool box, take out tool heads with handle during each replacing instrument and be connected, again no tool heads is put back to the tool box, therefore no tool heads and handle separate, knockdown characteristics are: function is many, but the operating procedure when using increases, and carries inconvenience.

The utility model content

The purpose of this utility model is to provide the convertible double-threaded screw cutter of easy conversion 1-shaped open of a kind of energy and cross mouth, can change the cutter head of 1-shaped open and cross mouth fast, the edge of a knife of work is exposed at outside the handle, fastening loosening 1-shaped open of energy and cross mouth screw, and the no edge of a knife is hidden in the handle.

For achieving the above object, the utility model adopts following technical proposals:

A kind of convertible double-threaded screw cutter comprises handle and screwdriver body, it is characterized in that all there is cutter head at the knife bar two ends of described screwdriver body, and the part cunning of knife bar is joined and is placed in the handle and its middle part is connected with handle can shirk the upset syndeton.

Above-mentioned handle and the shirked upset syndeton between the screwdriver body are: handle has center deep hole and screwdriver body cunning to join, and on the connector of handle and screwdriver body chute is arranged; The fixedly connected little fluted shaft in screwdriver body knife bar middle part, the two ends of this little transverse axis respectively with two square poles on aperture be rotatably assorted the chute slip inserting on described two square poles and the described handle connector.

There is the spherical little prominent point of semicircle the both sides, lower end of above-mentioned square bar and there is the opening sulculus at the center, and square bar lower end is cooperated with chute elastic compression on the handle connector.

Above-mentioned handle with shirked upset syndeton between the screwdriver body is: a flat-square blocks piece is fixedlyed connected at the knife bar middle part of described screwdriver body, the chute inserting on this flat-square shaped piece and the handle connector; Handle has center deep hole and screwdriver body cunning to join.

The two ends cutter head of above-mentioned screwdriver body is respectively 1-shaped open cutter head and cross mouth cutter head.

Above-mentioned handle of a knife is the nylon handle of a knife, and its connector also combines together for nylon connector and handle of a knife; Perhaps, handle of a knife is the nylon handle of a knife, fixedlys connected with handle of a knife and is integral and its connector is the metal connector.

A slice disc metab is rotatably connected bottom the above-mentioned handle.

The utility model has following conspicuous substantive distinguishing features and advantage compared with prior art.

This convertible double-threaded screw cutter has been equipped with the advantage of like product, have on this basis and possessed the function that like product does not have, select used cutter head by the upset of cutter hub, in the handle that temporary transient no cutter head is hidden in, leave in the tool box flow process of the replacing cutter head when having reduced work in and need not unload cutter head.Solved the other storage problem that unloads cutter head.

Cutter hub and handle are easy to connect, the transverse axis at cutter hub part center connects two fixedly square poles, parallel rotatable cutter hub with fixed bar, push in the chute that connects handle, need not bolt connects, as long as with finger pressure just can cutter hub and fixed bar push in the groove, when fixed bar enters chute fully, the fixed bar upper semi-circle automatically locks respective point in the chute by a meeting.Change the box-like screwdriver handling mode of traditional group, connector that need not third part.

The utilization of transparent colored handle, make convertible double-threaded screw cutter function and be appropriate harmony and the impulsive force that possesses visual sense of beauty in form, transparent handle has shown the internal structure of screwdriver, the alternative of open-and-shut prompting user's 1-shaped open and cross mouth cutter head, enrich VIS, improve the uninteresting vision impression of conventional screw-driver in order, the screwdriver of traditional integral type is opaque and has only one piece of cutter head tennis partner handle, style function singleness.
