Description
Affiliated technical field
The utility model relates to the hardware ﹠ tools field, especially, is a kind of screwdriver.
Background technology
In the five metals field, present screw is mainly by two kinds of cross and words, and to this, present screwdriver also is divided into two kinds of cross and words.In fact, the difference of Phillips screwdriver and straight screwdriver only is the cutter head part, and the remainder structure is identical, therefore, two kinds of screwdrivers can be integrated fully, thus the instrument of saving totle drilling cost, and the solution instrument carries the problem of burdensome and space hold.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of double-threaded screw cutter, and this double-threaded screw cutter can be realized fastening or loose the opening to a word screw and plus screw simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: this double-threaded screw cutter comprises handle of a knife, knife bar, described knife bar can move freely along described handle of a knife axis, and described knife bar one end is a word cutter head, the other end is the cross cutter head, a described word cutter head and cross cutter head inboard respectively are provided with a cross limited block, described handle of a knife two ends are provided with external screw thread, and has the cross recess that matches with described limited block that caves on described handle of a knife two end sections, described double-threaded screw cutter also comprises a sleeve, and described sleeve has the internal thread that matches with described handle of a knife two ends external screw thread.
As preferably, be provided with a block protection rubber in the described sleeve, not bad to protect described sleeve by described knife bar top.
As preferably, described handle of a knife surface has the coarse lines that is used to increase friction, and handle of a knife skids when preventing work.
The beneficial effects of the utility model are: this double-threaded screw cutter is when using the cutter head of any end, then the cutter head of the other end is pressed to handle of a knife, in described cross limited block submerges described cross recess, then described sleeve is tightened on the shank end of non-use side cutter head correspondence, then described knife bar linear degrees of freedom is vertically retrained by described sleeve, rotary freedom is retrained by described limited block, can adopt use side to carry out work.This double-threaded screw cutter is integrated two kinds of screwdrivers, thereby has saved the instrument totle drilling cost, and has solved the problem that instrument carries burdensome and space hold.
Description of drawings
Fig. 1 is the half sectional view of this double-threaded screw cutter.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
In the embodiment shown in fig. 1, this double-threaded screw cutter comprises handle of a knife 1, knife bar 2, described knife bar 2 can move freely along described handle of a knife 1 axis, and described knife bar 2 one ends are a word cutter head 21, the other end is a cross cutter head 22, a described word cutter head 21 and cross cutter head 22 inboards respectively are provided with a cross limited block 23, described handle of a knife 1 two ends are provided with external screw thread 11, and has the cross recess 12 that matches with described limited block 23 that caves on 1 liang of end section of described handle of a knife, described double-threaded screw cutter also comprises a sleeve 3, and described sleeve 3 has the internal thread 31 that matches with described handle of a knife 1 two ends external screw thread 11.
The concrete size of described sleeve 3 can be by the design of following relation: when the limited block 23 of described knife bar 2 non-use sides submerges in the described cross recess 12, the length that described knife bar 2 stretches out described handle of a knife 1 at this end adds the height of the external screw thread 11 of the above handle of a knife 1, equals the axial length of described sleeve 3 inner chambers.
Above-mentioned double-threaded screw cutter is provided with a block protection rubber 32 in the described sleeve 3, not bad by described knife bar 2 tops to protect described sleeve 3.
Above-mentioned double-threaded screw cutter, described handle of a knife 1 surface has the coarse lines that is used to increase friction, and handle of a knife 1 skids when preventing work.
Above-mentioned double-threaded screw cutter is when using the cutter head of any end, then the cutter head of the other end is pressed to handle of a knife 1, in described cross limited block 23 submerges described cross recess 12, then described sleeve 3 is tightened on the shank end of non-use side cutter head correspondence, then described knife bar 2 linear degrees of freedom vertically is by described sleeve 3 constraints, rotary freedom can adopt use side to carry out work by described limited block 23 constraints.This double-threaded screw cutter is integrated two kinds of screwdrivers, thereby has saved the instrument totle drilling cost, and has solved the problem that instrument carries burdensome and space hold.
