Abstract

The invention discloses a multifunctional screwdriver capable of regenerating a straight groove on a screw. The multifunctional screwdriver comprises a screwdriver handle and a screwdriver rod with the tail arranged in the screwdriver handle, a straight screwdriver head is arranged at the head of the screwdriver rod, and a saw blade corresponding to the screwdriver head in thickness is arranged on one side of the screwdriver rod. By arranging the saw blade on the screwdriver rod, when an original straight groove or a cross groove is worn, the straight groove can be formed by sawing for screwing-out of the screw.

Description

A kind of multifunctional screw driver
Technical field
The present invention relates to a kind of screwdriver, refer more particularly to a kind of multifunctional screw driver.
Background technology
In daily life, the usage frequency of screwdriver is very high.As everyone knows, the flat recess on screw or cross recess can wear and tear after repeatedly using, and make screw to be back-outed.
Summary of the invention
Technical problem to be solved by this invention is: the multifunctional screw driver that a kind of flat recess of can living again on screw is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of multifunctional screw driver, comprise: handle of a knife and its afterbody are arranged on the knife bar in handle of a knife, and the head of knife bar is provided with a word cutter head, and a side of described knife bar is provided with its thickness saw blade corresponding with cutter head.
The both sides of a described word cutter head are provided with chamfering, make the top of cutter head can adapt to the cross recess of plus screw afterbody.
The opposite side of described knife bar is provided with the auxiliary cutter head of strip.
On described handle of a knife, offer the arc groove that several are longitudinally arranged, between the edge of adjacent arc groove, be provided with fin between two.
The invention has the beneficial effects as follows: the present invention, by saw blade is set on knife bar, after original flat recess or cross recess wearing and tearing, can saw out a flat recess, and screw is back-outed; In addition,, because the both sides of cutter head are provided with chamfering, make the top of cutter head can twist a word screw and can twist plus screw again.
Accompanying drawing explanation
Fig. 1 is the structural representation of multifunctional screw driver of the present invention.
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Reference numeral in Fig. 1 to Fig. 2 is: 1, handle of a knife, 11, arc groove, 12, fin, 20, knife bar, 21, cutter head, 211, chamfering, 3, saw blade, 4, auxiliary cutter head.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, a kind of multifunctional screw driver of the present invention, comprise: handle of a knife 1 and its afterbody are arranged on the knife bar 20 in handle of a knife, the head of knife bar 20 is provided with a word cutter head 21, the both sides of one word cutter head 21 are provided with chamfering 211, make the top of cutter head 21 can adapt to the cross recess of plus screw afterbody, a side of described knife bar 20 is provided with its thickness saw blade corresponding with cutter head 21 3, and the opposite side of knife bar 20 is provided with the auxiliary cutter head 4 of strip; In the present embodiment, in order to increase the frictional force of handle of a knife 1, on described handle of a knife 1, offer the arc groove 11 that several are longitudinally arranged, between the edge of adjacent arc groove 11, be provided with fin 12 between two.
During use, after original flat recess or cross recess wearing and tearing, conventionally along original flat recess or cross grooving saw, go out a darker flat recess, thereby can easily screw be back-outed.
