Abstract

The utility model discloses a multi-function foldable ruler, which includes a ruler 1 and a ruler 2; the ruler 1 and the ruler 2 are connected flexibly. The ruler 1 and the ruler 2 are provided with length scale and angle scale. The ruler 2 is provided with a sliding groove 3; a screw 4 penetrates through the sliding groove 3 to connect the ruler 1 and the ruler 2 flexibly. One end of the ruler 1 is connected with compasses needle 5 flexibly. One end of the ruler 2 is connected with a pen core 4 flexibly. The compasses needle is fixed inside of a needle sleeve 7. The needle sleeve 7 is connected with the ruler 1 flexibly. A lead core 4 is fixed inside of a core sleeve 6. The core sleeve 6 is connected with the ruler 2 flexibly. The utility model multi-function foldable ruler can be used to measure length and can also measure angle, draw two intercrossing straight lines at any angle, draw parallel lines, which has compasses function and is compact and portable.

Description

Multi-functional folding rule

Technical field

The utility model relates to a kind of stationery, especially relates to a kind of multi-functional folding rule.

Background technology

At present, ruler used in everyday, useful in the time of can only or drawing straight line at measuring distance, function singleness; When taking measurement of an angle, need to use special protractor, when the needs painter's paraphernalia has the angle of intersection straight line, need ruler and protractor are used in combination, and drawing bowlder, and then needing to use special compasses, the someone has invented a kind of multifunctional ruler, on ruler, be distributed with various polygons such as triangle, square, rectangle, though easy to use, the ruler volume is bigger, and is not portable, feature size is often fixing, can't adjust as required.

The utility model content

The purpose of this utility model mainly is according to the deficiency of ruler function singleness in the existing life, and a kind of multi-functional folding rule is provided.

For realizing above purpose, the utility model is achieved through the following technical solutions:

Multi-functional folding rule, two rulers with length scale and angle index are movably connected.Preferably, have chute on the described ruler, screw passes chute two rulers is flexibly connected.Preferably, described ruler one end is connected with the compasses pin, and described another root ruler one end is connected with lead for retractable pencil.

More preferably be, the compasses pin is fixed in the needle guard, and needle guard and ruler flexibly connect, and lead for retractable pencil is fixed in the core retainer plate, and core retainer plate and another ruler flexibly connect.

Multi-functional folding rule in the utility model can measured length, and can take measurement of an angle, draw two intersecting straight lines at any angle, draws parallel lines, and have the compasses function simultaneously, and volume is little, and is easy to carry.。

Fig. 1 is the structure chart of the utility model first embodiment;

Fig. 2 is the structure chart of the utility model second embodiment;

User mode figure when Fig. 3 a and Fig. 3 b draw parallel lines for using the utility model;

Fig. 4 takes measurement of an angle for use the utility model or draws angle line user mode figure.

The specific embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is done a detailed description:

Referring to Fig. 1 is the utility model first embodiment, and multi-functional folding rule comprises ruler 1, and ruler 2 has length scale and angle index on ruler 1 and the ruler 2, has chute 3 on the described ruler 2, and screw 4 passes chute 3 ruler 1 and ruler 2 are flexibly connected.

Referring to Fig. 2 is the utility model second embodiment, and on the first embodiment basis, increase with lower member: compasses pin 5 is fixed in the needle guard 7, and needle guard 7 flexibly connects with ruler 1, and lead for retractable pencil 4 is fixed in the core retainer plate 6, and core retainer plate 6 flexibly connects with ruler 2.

During use, promptly can use multi-functional folding rule of the present utility model to measure length, draw parallel lines, as shown in Figure 3; Take measurement of an angle or draw angle line, as shown in Figure 4.Can also be used as compasses, as shown in Figure 2.

Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
