Abstract

The utility model discloses a multi-purpose ruler which comprises a rivet, a graduated scale, a needle and a fixed sleeve; a vertex angle (3) of 30 DEG is arranged at one end of the graduated scale (2), and the needle (6) is arranged at the other end of the graduated scale (2). The fixed sleeve (7) is installed at one end of the graduated scale (1) for fixing a circle drawing tool, a protractor comprising an arc (8), an arc (9) and an arc (10) is arranged at the position 5cm far away from the fixed sleeve, wherein the arc (10) and the inner margin of the graduated scale (1) are hollow, the space between the arc (8) and the arc (9) is hollow, angle graduations ranging from 0 to 180 are marked between the arc (9) and the arc (10), a vertex angle (4) of 40 DEG is arranged at the other end of the graduated scale (1), and the rivet (5) is arranged 5cm far away from the two vertex angles to connect the two graduated scales together. The utility model has advantages of broad purposes, thin ruler body, low cost and convenient placement.

Description

Multipurpose ruler

Technical field

The utility model belongs to a kind of schooling apparatus, particularly a kind of ruler that has compasses and protractor.

Background technology

The multifunctional compass chi of China Patent No. 01206671.0 discloses a kind of drafting instrument that can be simultaneously uses as compasses and ruler, but its complex structure, and can not use as protractor simultaneously, therefore operation very bothering cost also high.

The utility model content

The purpose of this utility model is to address the above problem, and releases a kind of simple in structurely, with low cost, integrates the Multipurpose ruler of compasses, protractor.

The technical problem that the utility model proposed is to solve like this: a kind of Multipurpose ruler is made up of Liu Ding, rule, syringe needle, fixed cover.Wherein Liu Ding connects two rules, rule 2 one ends are equipped with syringe needle 4 and the other end, and drift angle 3 is arranged is 30 °, rule 1 one ends are equipped with fixed cover 7 to consolidate picture circle apparatus etc., and one protractor is arranged at distance fixed cover 5cm place, be made up of arc 8,9,10, wherein arc 10 is hollow with rule 1 inward flange, indicates the angle index between the 0-180 between arc 9 and the arc 10, be hollow between arc 8 and the arc 9, at the other end drift angle 4 being arranged is 60 °.Drift angle 3 is 5cm with the summit of drift angle 4 apart from Liu Ding 5.The 2cm graduation mark place of rule 1 when top margin 11 expands into straight line at two rules.

The beneficial effects of the utility model are, possess the function of compasses, rule, protractor and simple to operate simultaneously, and it is extensive to be suitable for the crowd.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, two rules are connected by Liu Ding 5, wherein fixed cover 7 is fixed on above the rule 1, the protractor that arc 8,9,10 is formed is at distance fixed cover 5cm place, wherein arc 10 is hollow with rule 1 inward flange, indicating the angle index between the 0-180 between arc 9 and the arc 10, is hollow between arc 8 and the arc 9, and it is 60 ° that the other end of rule 1 has drift angle 4.Syringe needle 4 is arranged on rule 2, and at the other end drift angle 3 being arranged is 30 °.Two rule drift angle vertex distance Liu Ding 5 are 5cm.

As shown in Figure 2, when two rules expanded into straight line, top margin 11 was at the 2cm of rule 1 graduation mark place.

Claims (1)

1, a kind of Multipurpose ruler comprises: rule (1), (2), Liu Ding (5), syringe needle (6) and fixed cover (7) is characterized in that: rule (1), (2) are connected by Liu Ding (5); Rule (1) one end is equipped with fixed cover (7), there are arc (8), (9), (10) in the 5cm place at distance fixed cover (7), be hollow between arc (10) and rule (1) inward flange wherein, be hollow between arc (8), (9), indicate the angle index of 0-180 between arc (9), (10), at the other end drift angle (4) being arranged is 60 °; Rule (2) one ends have syringe needle (6), and it is 30 ° that the other end has drift angle (3), and apart from 5cm place, two drift angle summits one Liu Ding (5) are arranged; When rule (1) and rule (2) when expanding into straight line, top margin (11) is at the 2cm graduation mark place of rule (1).
