Abstract

The utility model provides a precision ruler which comprises a ruler body, scale marks arranged on the ruler body and a handle arranged on the ruler body, wherein the handle is perpendicular to the plane where the ruler body is located and the scale marks are through groove-shaped. The utility model with simple structure and low manufacturing cost can effectively provide the convenience to take and use the precision ruler for people and also ensure the accuracy of drawing the mark line, thereby improving the use effect.

Description

A kind of precision chi

Technical field

The utility model relates to a kind of precision chi, relates in particular to a kind of precision chi with handle.

Background technology

The precision chi is a kind of teaching appliance commonly used, and it can be measured and draw very easily, is convenient to the teacher and demonstrates.But because an existing precision chi dimensioning often, thereby in use, also can cause certain problem.For example, when making by hand or chart, usually according to certain length marking line.But, because the angle of looking with the scale of chi is different, or the collimation error that causes of the intrinsic diameter of pen core itself, make the precision of institute's marking line always have problems, like this, just make the material that intercepts and the precision of drawing reduce greatly.Simultaneously,, after always needing earlier set square to be moved on to a limit, just can pick up then, also bring inconvenience to use if the sheet material of making is taken up.Therefore, need a kind of can conveniently the use, can guarantee the precision chi of marking line precision again.

The utility model content

Technical problem to be solved in the utility model is that providing a kind of can conveniently use, and can guarantee the precision chi of marking line precision again.

In order to address the above problem, the technical solution of the utility model is such: a kind of precision chi, comprise the ruler main body, and be marked with scale on this ruler main body, described ruler main body is provided with handle, and this handle is vertical with the plane at ruler main body place.By this structure, can be convenient for people to more convenient service precision chi, thereby prevent and the sheet material of making will be taken up, after always needing earlier set square to be moved on to a limit, the problem that just can pick up then.As a kind of embodiment of the present utility model, described scale is a groove, thus marking line easily.

Beneficial effect: this programme is simple in structure, and cost of manufacture is low, and the precision chi of can realizing effectively being convenient for people to use carries out various measurement activities, can also guarantee the precision of marking line, improves result of use.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

A kind of precision chi comprises ruler main body 10, is marked with scale 10a on this ruler main body 10, and described scale 10a is a groove, and in addition, described ruler main body 10 is provided with handle 20, and this handle 20 is vertical with the plane at ruler main body 10 places.

During use, arrest handle 20 on the ruler main body 10, promptly can easily the precision chi that lies on desktop or the flat board be picked up, thereby prevent and the sheet material of making will be taken up with hand, after always needing earlier set square to be moved on to a limit, the problem that just can pick up then.Simultaneously, because each scale is made groove 10a, make cutter, scriber or pen, can directly be inserted among the groove 10a and mark graticule, guaranteed the accurate of the graticule of doing, so just can prevent because the angle difference that the scale of chi is looked, or the collimation error that causes of the intrinsic diameter of pen core itself, more convenient is people's uses.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims (2)

1. a precision chi comprises the ruler main body, is marked with scale on this ruler main body, it is characterized in that, described ruler main body is provided with handle, and this handle is vertical with the plane at ruler main body place.

2. precision chi according to claim 1 is characterized in that, described scale is a groove.
