Abstract
The invention provides a long screw, which comprises a screw rod (1) and a screw cap (2), wherein the screw cap (2) is provided with threads. According to the long screw provided by the invention, a friction force between the screw and hands can be increased through the threads arranged on the screw cap, thereby the screw is screwed with hands in a more convenient and labor-saving manner.
Description
Technical field
The present invention relates to a kind of long spiro nail.
Background technique
Screw is widely used as the combining structure of parts; As the mechanism that fastening such screw is used, general in the past practical following mechanism: form " straight groove " of " cross bore " or the formation minus sign shape of plus sign shape at the top of screw, these mechanisms when in use; Usually can cooperate practical with the corresponding screw-driver of top shape; When some do not find screw-driver, sometimes directly tighten or unscrew screw, still through staff's hand; The nut of some screws on the present stage market is generally smooth surface, comparatively requires great effort when twisting screw.
Summary of the invention
For solving the problems of the technologies described above, the invention provides and a kind ofly can conveniently twist a kind of long spiro nail of getting screw.
For realizing above-mentioned purpose, the invention provides a kind of long spiro nail, comprise screw rod and nut, said nut is provided with screw thread.
More excellent is that the screw thread on the said nut is the annular knurl screw thread.
More excellent is that said screw rod and nut are formed in one.
More excellent is, said screw rod is thin formula gradually.
The advantage of a kind of long spiro nail of the present invention is: the screw thread that is provided with through nut can increase the friction of screw and hand, thereby convenient laborsaving when making hand-turn a screw.
Description of drawings
Fig. 1 is the structural representation of a kind of long spiro nail of the present invention.
Among the figure:
The 1-screw rod; The 2-nut.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1, a kind of long spiro nail comprises screw rod 1 and nut 2, and nut 2 is provided with the annular knurl screw thread, and screw rod 1 wherein is formed in one with nut 2, and screw rod 1 is formula carefully gradually.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
