The straight ruler comprises a ruler body provided with scales, wherein the ruler body is composed of more than two sections of short rulers which are mutually sleeved; each short ruler comprises an accommodating short ruler and an accommodated short ruler; each accommodating short ruler is internally provided with a cavity capable of accommodating the accommodated short ruler. The straight ruler is composed of more than two sections of short rulers which are mutually sleeved, and the short rulers can be telescopic and stretched, so that the straight ruler is convenient to use and accommodate, and is convenient and practical.
Description
Technical field
The present invention relates to a kind of measurer, be specifically related to a kind of ruler.
Background technology
Straight ruler, is used for measuring length. and be widely used in mathematics, measure the subjects such as engineering.Ruler has the chi shape gauge of accurate straight line seamed edge.Ruler, also can be together with gauge block, for check length size for carrying out straight line degree measurement and the measurement of planeness with light gap method.Ruler also have person be between chi, be a kind of very conventional measuring length instrument, this stationery is very general, almost every pupil one of staff all, is generally used for measuring shorter distance or draws straight line.Use: measure distance, draw straight line.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ruler that can shrink and stretch.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of ruler, comprise the graduated blade of tool, and described blade consists of the above short chi of two joints being mutually socketed; Described short chi comprises to be taken in short chi and is contained short chi, described in take in and in short chi, be provided with the cavity that is contained short chi described in can holding.
The invention has the beneficial effects as follows: the present invention consists of the above short chi of two joints being mutually socketed, and between short chi, can shrink and stretch, easy to use with take in, convenient and practical.
On the basis of technique scheme, the present invention can also do following improvement.
Further, between described short chi, by anti-drop structure, connect.
Further, described anti-drop structure is shell fragment.
Further, the end that in the end a joint is contained short chi is provided with is convenient to the projection that stretches.
Accompanying drawing explanation
Fig. 1 is the structural representation of ruler of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, take in short chi, 2, be contained short chi, 3, anti-drop structure, 4, projection.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A ruler, comprises the graduated blade of tool, and described blade consists of the above short chi of two joints being mutually socketed; Described short chi comprises to be taken in short chi 1 and is contained short chi 2, described in take in and in short chi 1, be provided with the cavity that is contained short chi 2 described in can holding.
Between described short chi, by anti-drop structure 3, connect.
Described anti-drop structure 3 is shell fragment.
The end that in the end a joint is contained short chi 2 is provided with is convenient to the projection 4 that stretches.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
