Abstract
The utility model relates to a new screw which is suitable for spanners with various calibers. The screw is an angular screw, composed of a nut and a screw rod. A plurality of nonadjacent surfaces are divided into a plurality of groups which are respectively processed according to the calibers of different spanners. The screw can be used to turn two or more kinds of spanners with different calibers; therefore, the screw can shorten the time for looking for spanners and meanwhile reducing the number of the spanners that are used.
Description
Affiliated technical field
The utility model relates to a kind of screw, especially can the enough two kinds screws that (more than reaching) bore spanner rotates.
Background technique
At present, known normal screws is a regular polygon, can only rotate with a kind of specified caliber spanner.But, because each spanner generally has only a kind of bore, so also will seek the spanner of suitable bore when using; And need carry a large amount of spanners, very inconvenient.
Summary of the invention
Can only be with the deficiency of a kind of bore spanner rotation in order to overcome existing normal screws.The utility model provides a kind of screw, comprises nut and screw rod.The spanner rotation of enough two kinds (more than reaching) bores of this screw energy.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of screw that is fit to multiple bore spanner, comprise nut and screw rod, it is polygonal that nut is overlooked profile, nut has the corresponding surface that some groups of non-conterminous sides are formed, each group corresponding surface has and the corresponding size of different spanner bores, and the nut corresponding surface is two groups or more integer group.Adopt polygonal screw, get non-conterminous several faces and be divided into some groups, general every pair of corresponding surface is one group.Process by different spanner caliber sizes for every group.For example, adopt anistree screw, get non-conterminous four faces and be divided between two groups.Process by different spanner caliber sizes between two groups.One group is adopted the 12mm caliber size, and another group adopts the 13mm caliber size to process.Like this, this screw can rotate with 13-15 bore spanner again with the rotation of 12-14 bore spanner, and by that analogy, the screw of 8 limit shapes can accomplish to be fit to 4 kinds of spanners at most.
The beneficial effects of the utility model are the spanner rotation of enough two kinds (more than reaching) bores of a kind of screw energy.Can save the time of seeking spanner, reduce the spanner use amount simultaneously, raise labour efficiency and economic benefit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of profile plan view of the present utility model,
Fig. 2 is a kind of embodiment of model utility.
Screw limit number is desirable multiple among Fig. 1.
A: a kind of caliber size, b: another kind of caliber size.(a, b preferably get adjacent caliber size)
Embodiment
As Fig. 2, adopt anistree screw, get non-conterminous four faces and be divided between two groups.Process by different spanner caliber sizes between two groups.In Fig. 2, what we chose is one group of employing 12mm caliber size, the processing that another group adopts the 13mm caliber size to carry out.
Claims (2)
1. a screw that is fit to multiple bore spanner comprises nut and screw rod, and it is polygonal that nut is overlooked profile, it is characterized in that: nut has the corresponding surface that some groups of non-conterminous sides are formed, and each group corresponding surface has and the corresponding size of different spanner bores.
2. screw according to claim 1 is characterized in that: the nut corresponding surface is two groups or more integer group.
