Abstract
The invention relates to a compasses and ruler combined tool, in particular to a multifunctional compasses and ruler combined tool which can be used as (a pair of) compasses, a graduation ruler and a protractor. The multifunctional compasses and ruler combined tool comprises a main graduation ruler and an auxiliary graduation ruler which are connected together through a shaft and is characterized in that the tail end of the main graduation ruler is connected with a fixing needle, the tail end of the auxiliary graduation ruler is connected with a mechanical pencil, the top end of the auxiliary graduation ruler is connected with a compasses pole, the tail end of the auxiliary graduation ruler is connected with an angle measuring ruler through a rotating shaft, and the angle measuring ruler is placed in a groove of the auxiliary graduation ruler; an eraser is mounted on the side surface of the main graduation ruler through an eraser clamping groove, an illuminating LED lamp, a switch and a button battery which are connected through wires are further mounted on the side surface of the main graduation ruler, and the button battery is mounted on the main graduation ruler through a battery clamping groove. The multifunctional compasses and ruler combined tool has the benefits as follows: the tool can be simultaneously used as the graduation ruler, the compasses and the protractor and is simple in structure, convenient to use and carry and space-saving.
Description
(1) technical field
The present invention relates to a kind of compasses, ruler combination instrument, the multifunctional compass that can use simultaneously as compasses, rule and protractor particularly to a kind of, ruler combination instrument.
(2) background technology
The subject such as mathematics, physics is a lot of when needing to map, and will use the instruments such as rule, compasses and protractor unavoidably, under current technology during mapping, these instruments that market is sold are all independent, it is accomplished by when student uses buying multiple types of tools, had both occupied more space, and carried and very inconvenient.Therefore, it is badly in need of a kind of instrument, the several functions such as rule, compasses and protractor can be integrated, service for students in middle and primary schools instantly.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, multifunctional compass easy to use, portable, ruler combination instrument.
The present invention is achieved through the following technical solutions:
A kind of multifunctional compass, ruler combination instrument, including the master calibration chi linked together by axle and auxiliary rule, it is characterized in that: described master calibration chi end is connected with fixing pin, auxiliary rule end is connected with propelling pencil, auxiliary rule top is connected with compasses bar, auxiliary rule end is connected to angle square by rotating shaft, and angle square is placed in the groove of auxiliary rule；Master calibration ulnar surface is provided with rubber by rubber draw-in groove, and master calibration ulnar surface is also equipped with the illuminating LED lamp, switch and the button cell that are connected by wire, and master calibration chi installs button cell by battery draw-in groove.
The invention has the beneficial effects as follows: can use simultaneously as rule, compasses and protractor；Simple in construction, easy to use, be easy to carry, save space, it is greatly convenient to bring for the learning life of classmates.This product can also use in rather dark place, opens illuminating lamp.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is the structural representation of the present invention；
In figure, 1 axle, 2 master calibration chis, 3 auxiliary rules, 4 fixing pins, 5 propelling pencils, 6 compasses bars, 7 rotating shafts, 8 angle squares, 9 grooves.10 rubbers, 11 illuminating LED lamps, 12 switches, 13 button cells.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes the master calibration chi 2 and the auxiliary rule 3 that are linked together by axle 1, master calibration chi 2 end is connected with fixing pin 4, auxiliary rule 3 end is connected with propelling pencil 5, auxiliary rule 3 top is connected with compasses bar 6, auxiliary rule 3 end is connected to angle square 8 by rotating shaft 7, and angle square 8 is placed in the groove 9 of auxiliary rule 3；Master calibration chi 2 side is provided with rubber 10 by rubber draw-in groove, and master calibration ulnar surface is also equipped with the illuminating LED lamp 11, switch 12 and the button cell 13 that are connected by wire, and master calibration chi installs button cell by battery draw-in groove.
Adopt a kind of multifunctional compass of the present invention, ruler combination instrument, when using as rule, directly master calibration chi 2 and auxiliary rule 3 are closed up by axle 1, use the scale on surface.When using as calipers function, master calibration chi 2 and auxiliary rule 3 being separated by the effect of axle 1, use fixing pin 4 fixing on paper, hold compasses bar 6 and rotated by auxiliary rule 3, propelling pencil 5 can draw required circle on paper.When using as function of angle gauge, master calibration chi 2 and auxiliary rule 3 are separated by axle 1, master calibration chi 2 and auxiliary rule 3 is made to overlap with two limits at required angle respectively, angle square 8 is pulled out under rotating shaft 7 acts on, make it vertical with master calibration chi 2, the angle marked on angle square 8 is the angle at required angle, and on angle square, marked angle is the angle value drawn according to antitrigonometric function.
Claims (1)
1. a multifunctional compass, ruler combination instrument, including the master calibration chi (2) linked together by axle (1) and auxiliary rule (3), it is characterized in that: described master calibration chi (2) end is connected with fixing pin (4), auxiliary rule (3) end is connected with propelling pencil (5), auxiliary rule (3) top is connected with compasses bar (6), auxiliary rule (3) end is connected to angle square (8) by rotating shaft (7), and angle square (8) is placed in the groove (9) of auxiliary rule (3)；Master calibration chi (2) side is provided with rubber (10) by rubber draw-in groove, master calibration chi (2) side is also equipped with the illuminating LED lamp (11), switch (12) and the button cell (13) that are connected by wire, by battery draw-in groove installation button cell on master calibration chi.
