Description
Technical field
The utility model is related to fastening member technical fields, more particularly to a kind of screw and screwdriver.
Background technology
Screw (screw) is using the physics and mathematical principle of the inclined-plane circular rotating and frictional force of object, in proper order gradually
The tool that implements parts are fastened into ground is industrial necessity indispensable in daily life, is all sent out in the every field of life
Wave important function.
The groove profile of " ten " the font screw being commonly used is as depicted in figs. 1 and 2, the center of groove 10 or use Fig. 1
Shown in right-angle design, or use circular-arc-shaped design shown in Fig. 2.The power that traditional screwdriver acts on screw is mainly concentrated
In on the contact point in 10 centre of groove, as shown in figure 3, causing centre to be easy deformation, to damaged screws；And groove
10 centers are easier to deform upon using the screw of circular-arc-shaped design groove profile.
When screw because the reasons such as firmly excessive or usage time is long when tightening, screw outer surface is corroded, make
After surface is destroyed, Unscrewed screw again is tended not to using common screwdriver, or even situation can be made more to deteriorate.Daily
In life, people encounter this problem, and rubber band is usually used and increases frictional force, rubber band is placed on the groove of screw, so
Rubber band rotation screw is pushed down with what screwdriver was exerted oneself afterwards, screw, which will be swapped out, to be come.In engineering field, the tool of master worker
More, the method for use is also more, for example can be connect with electricity consumption drill straight and go to sticks and staves tommy bar, but this method can make the silk of screw
Clast stick in the silk slot of periphery, new screw can not be embedded at all, therefore the method is using less.It secondly, can be with
The gap for pulling up a line-styled in screw with hacksaw, is then produced with the screwdriver of line-styled, but the method
It is helpless for the screw for being embedded in consistent with body surface in object.The above settling mode is all comparatively laborious, laborious, effect
Also not fully up to expectations.
How to design it is a set of be not easy to twist the bad screw with high availability, screwdriver, the prior art not yet provides solution
Scheme.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of screw and screwdriver, increases screw and screw
The contact area of knife improves the service life of screw to reduce the abrasion of screw.
A kind of screw provided by the utility model includes head and the lead screw that is connect with head, and head is provided with for spiral shell
The groove of silk knife insertion, is provided with screw thread in lead screw, head is additionally provided with groove, is connected at groove and the endpoint of groove.
Preferably, the groove is "-" type groove.
Preferably, the groove is cruciate groove.
Preferably, the groove is hemispherical groove.
Preferably, the groove is square groove.
A kind of screwdriver provided by the utility model includes bar portion and work head, and work head includes the knife for being embedded in groove
Head, and, the protrusion for being embedded in groove.
Preferably, the cutter head is "-" type cutter head.
Preferably, the cutter head is cross cutter head.
Preferably, the protrusion is hemispherical.
Preferably, the protrusion is rectangular.
Preferably, the screwdriver includes several various sizes of work heads, between each work head by way of nested
It connects.
The groove being connected to groove is arranged in screw head, and is arranged in the work head of screwdriver for the utility model
Protrusion for being embedded in groove, to increase the contact area of screwdriver and screw so that screw be not easy twist it is bad, twist
It is more laborsaving, improve service efficiency.
Description of the drawings
Fig. 1, Fig. 2 are the structural schematic diagrams on existing cross screw head；
Fig. 3 is the schematic diagram of screwdriver insertion screw in the prior art；
Fig. 4 is the structural schematic diagram for the screw head that the utility model embodiment provides；
Fig. 5 is the sectional view for the screwdriver that the utility model embodiment provides；
Fig. 6 is the schematic diagram for the screwdriver insertion screw that the utility model embodiment provides.
Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the utility model is illustrated.
As shown in figure 4, screw embodiment provided by the utility model includes head and the lead screw that is connect with head, screw
Screw thread is provided on bar, Fig. 4 is the structural schematic diagram of screw head, and the groove being embedded in for screwdriver is provided on screw head
10, it is additionally provided with groove 11, is connected at groove 11 and the endpoint of groove 10.
In the present embodiment, the groove 10 of screw is screw common structure, and groove profile includes but not limited to "-" type or cross
Type.The groove 11 of screw is newly-increased structure, and groove profile includes but not limited to hemispherical or rectangular.If screw is minus screw,
A groove 11 is respectively arranged at groove both ends in screw；If screw is cross screw, screw is set respectively at the both ends of two grooves
Set a groove 11.Also, the groove of arbitrary shape can expand screwdriver and screw contact area, and reaching reduces screw mill
The effect of damage.
In the present invention, the size of the groove of screw can be adjusted compared to existing screw, can not also be adjusted.
If do not adjusted, screw can be compatible with the conventional screwdriver of the prior art.
The utility model additionally provides a kind of embodiment of screwdriver, and screwdriver includes bar portion and work head, work head packet
The cutter head 20 for being embedded in groove 10 is included, and, the protrusion 21 for being embedded in groove 11, the sectional view of work head is as shown in Figure 5.
Wherein, cutter head 20 is common driver bit structure, such as：Slotted point screwdriver cutter head, Philips-type screwdriver bit；It is common
Driver bit be tip, however, the utility model embodiment can also adopt the cutter head for plane.Protrusion 21 is and screw recess
The shape to match each other, such as：Hemispherical, annulus, rectangular etc..
When the screwdriver and screw provided using the use of the new type, as shown in fig. 6, the protrusion on the four edges of screwdriver
Structure is just exactly matched with the groove of screw so that screwdriver acts on the stress point of screw by the central part of screw weakness
Bits Expanding increases forced area, so that being more uniformly stressed for screw, reduces spiral shell to the larger position of peripheral hardness
The abrasion of silk；Also, is increased based on stress radius, be conducive to the principle for changing object moving state so that the action of the turn of the screw
It is more laborsaving.
In addition, the utility model additionally provides a kind of screwdriver of nested type, realize that the work head of multiple and different specifications is logical
It crosses nested mode to be integrated on a screwdriver, all includes cutter head and the structure of protrusion two, and be for each work head
It is telescopic.In this way, in actual use, the work head for meeting demand and pull-out are picked out from each work head.
Shown in sum up, the utility model provides a kind of screw and screwdriver, improves coincideing for screwdriver and flight
Degree, increases the contact area of screwdriver and flight, keeps the turn of the screw more laborsaving, improve work efficiency.Meanwhile it reducing
The abrasion of screw improves the service life of screw, economizes on resources.Since use of the screw in life is very extensive, so
The utility model has significant practical value.
Obviously, the above embodiment is only intended to clearly illustrate the utility model example, and is not to this
The restriction of the embodiment of utility model.For those of ordinary skill in the art, on the basis of the above description also
It can make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And this
Protection model of the obvious changes or variations that a little spirit for belonging to the utility model are extended out still in the utility model
Among enclosing.
