Easy set screw
The utility model relates to a kind of screw, more particularly, relates in particular to a kind of easy set screw.
Existing screw generally is made of nut and screw rod, and the structure of nut generally has two kinds, and a kind of is that the nut cross section is circular, is provided with straight groove or cross recess at the nut top surface; A kind of is that the nut cross section is a polygonal, and as square, regular hexagon, and nut integral body is solid.In operation, the former can only tighten or unscrew with the instrument of screw-driver one class that adapts with straight groove or cross recess, and the latter can only tighten or unscrews by the spanner or the pliers of other types, when screw is used for the corner of article or slit, just exist and to use the screw-driver or the situation of spanner, cause and to tighten or to unscrew screw.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, can be suitable for the easy set screw of multiple instrument simultaneously.
The technical solution of the utility model is achieved in that a kind of easy set screw, comprises nut and screw rod, is provided with locating slot at the nut top surface, wherein, described nut cross section be shaped as polygonal.
In the above-mentioned easy set screw, described nut cross section be shaped as square.
In the above-mentioned easy set screw, described nut cross section be shaped as regular hexagon.
In the above-mentioned easy set screw, also be provided with pad between described nut and the screw rod, the overall structure that nut, screw rod and pad are one of the forming.
The utility model by at the nut top surface locating slot being set, is designed to polygonal with the nut cross section after adopting said structure simultaneously, when adapting to screw-driver, also can adapt to wrench operated, improved the adaptability of screw greatly, make it be easier to fix, adaptability is stronger.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure: nut 1, screw rod 2, locating slot 3, pad 4.
Consult Fig. 1, shown in Figure 2, easy set screw of the present utility model comprises nut 1 and screw rod 2, between nut 1 and screw rod 2, also be provided with pad 4, the overall structure that nut 1, screw rod 2 and pad 4 are one of the forming, more convenient use, saved needs to add the trouble of overlapping pad in the past.Be provided with locating slot 3 at nut 1 top surface, in the present embodiment, locating slot 3 is a cross recess, can certainly be straight groove, is determined on a case-by-case basis, and makes it adapt to various screw-drivers.Further, nut 1 cross section be shaped as regular hexagon, make it tighten or unscrew operation by spanner.Certainly, the shape of nut 1 cross section also can be a square, can be other polygon structure also, is determined on a case-by-case basis.
