Abstract
The invention discloses a novel screw driver structure. The novel screw driver structure comprises a screw driver handle and a screw driver body. The screw driver body comprises a screw driver rod and a screw driver head arranged at one end of the screw driver rod, the other end of the screw driver rod is fixed inside the screw driver handle, the screw driver body is made of hard alloy, the outer surface of the screw driver head is provided with a first hard layer, and the outer surface of the first hard layer is provided with a second hard layer. By means of the method, the screw driver head is high in hardness and can be used for trimming a groove in a screw, and the novel screw driver structure is simple and practical.
Description
Technical field
The present invention relates to hand tools technical field, particularly relate to a kind of screw knife structure.
Background technology
Screwdriver is that a kind of to be used for twisting screw be that a kind of important machine tool ， family screwdriver is also the household appliance of people's daily life indispensability to force its instrument ， factory screwdriver in place.Screwdriver is conventional slotted point screwdriver, cross screwdriver etc.
Screwdriver in use, when the opening deglabration of head of screw is skidded, people's screwdriver that often pounds with a hammer, it is darker that cutter head by screwdriver picks the groove of screw, is convenient to screw to back out, and the hardness of existing driver bit is inadequate, when tick slot, easily cause cutter head to damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of screw knife structure, and cutter head hardness is high, can be used for picking the groove of screw, simple and practical.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of screw knife structure is provided, comprise: handle of a knife and cutter hub, described cutter hub comprises knife bar and is arranged on the cutter head of described knife bar one end, the other end of described knife bar is fixed in handle of a knife, described cutter hub adopts carbide alloy to make, and is provided with the first hard layer on the outer surface of described cutter head, is provided with the second hard layer on the outer surface of described the first hard layer.
In a preferred embodiment of the present invention, described the first hard layer is carbide layers.
In a preferred embodiment of the present invention, described the second hard layer is hard chromium layers.
In a preferred embodiment of the present invention, on the front end face of described handle of a knife, be provided with light source.
The invention has the beneficial effects as follows: the screw knife structure that the present invention discloses, cutter head hardness is high, can be used for picking the groove of screw, simple and practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of screw knife structure one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, handle of a knife, 2, knife bar, 3, cutter head, 4, light source.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of screw knife structure, comprise: handle of a knife 1 and cutter hub, described cutter hub comprises knife bar 2 and is arranged on the cutter head 3 of described knife bar 2 one end, the other end of described knife bar 2 is fixed in handle of a knife 1, and described cutter hub adopts carbide alloy to make, and is provided with the first hard layer on the outer surface of described cutter head 3, on the outer surface of described the first hard layer, be provided with the second hard layer, make cutter head 3 there is enough hardness, can be used for picking the groove of screw, be convenient to screw to screw down.
Described the first hard layer is carbide layers.
Described the second hard layer is hard chromium layers.
On the front end face of described handle of a knife 1, be provided with light source 4, can throw light on, be convenient to screwdriver and use night.
The screw knife structure that the present invention discloses, cutter head hardness is high, can be used for picking the groove of screw, simple and practical.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
