Abstract

The utility model discloses a pencil with a length rule and an angle rule. Two symmetrical lateral faces of a rod part of the pencil are respectively provided with the length graduation rule and the angle graduation rule, and the structural shape of the angle graduation rule is in the structural shape of a straight rule. Except the function of the conventional pencil, the utility model also has the functions of length and angle measurement. When the length is measured, the length can be directly measured by the length graduation ruler. When an angle is measured, first points are respectively taken from two edges of an included angle of an angle to be measured by the length graduation rule, then distances of the two points to the vertex are both 4 centermeters, and the two points are measured by the angle graduation rule, so that the degree of the angle to be measured can be directly read.

Description

The pencil that has length chi and bevel protractor

Technical field:

The utility model relates to a kind of pencil that has length chi and bevel protractor, belongs to the pencil manufacture technology field.

Background technology:

At present, pencil of the prior art generally only has the function of writing, and can not use as measuring length or angle, and its function ratio is more single, and is therefore still convenient inadequately in use.

Summary of the invention:

The purpose of this utility model is: a kind of existing writing function is provided, the pencil that has length chi and bevel protractor of measuring the length or the function that takes measurement of an angle is arranged again, to overcome the deficiency of existing pencil.

The utility model is to constitute like this: it comprises pencil (1), is respectively equipped with length graduated scale (2) and angle index scale (3) on the bar portion symmetry two sides of pencil (1); The planform of angle index scale (3) is the ruler planform.

Owing to adopted technique scheme, the utility model is compared with existing pencil, and the utility model is except the function with conventional pencil, and the utility model also has the function that can measure length and angle.When measuring length, adopt length graduated scale (2) can directly measure length; When taking measurement of an angle, earlier on two angle limits of measured angle, get a point respectively with length graduated scale (2), make these two points all be 4 centimetres, use angle index scale (3) to measure these two points then and can directly read the number of degrees of this tested angulation to the distance on the summit of measured angle.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment:

Embodiment of the present utility model: pencil (1) can adopt conventional circular or six prismatic pencils, during making, produce length graduated scale (2) and angle index scale (3) respectively on the bar portion symmetry two sides of pencil (1), the scale of length graduated scale (2) is made the method making of length rule routinely; When making angle index scale (3), its planform is made as the planform of ruler, the minimum calibration degree of being made as of its scale, the length value of the every degree of its scale can be determined by the following method:

On two angle limits of standard angle 1 degree, get a point respectively, making these two points all is certain distance (this distance is 4 centimetres in the present embodiment) to the distance on the summit of standard angle, and the distance of measuring these two points with the length chi promptly gets the length value of every degree scale (length value of the every degree of angle index scale is 0.0696 centimetre in the present embodiment then.

Claims

1, a kind of pencil that has length chi and bevel protractor, it comprises pencil (1), it is characterized in that: be respectively equipped with length graduated scale (2) and angle index scale (3) on the bar portion symmetry two sides of pencil (1).

2, the pencil that has length chi and bevel protractor according to claim 1 is characterized in that: the planform of angle index scale (3) is the ruler planform.
