Abstract
The utility model relates to a multi-purpose drawing tool, in particular to a combined tool, which is formed by integrating a protractor, a ruler and compasses for conveniently drawing. The utility model is composed of a protractor a, a protractor b, a length scale a, a length scale b, a 0 starting point a, a 0 starting point b, small holes of various shapes, a small box, the compasses, a student rule and a bayonet. The multi-purpose drawing tool is characterized in that the student rule is commonly composed of the protractor a, the protractor b, the small box, the 0 starting point a, the 0 starting point b and the bayonet; the small box is arrange at the center of the student ruler; the compasses are arranged in the small box; the bayonet is arranged in the small box; and the compasses are clamped by the bayonet. Because the functions of a protractor, a set square and a straight ruler are integrated on a type face, and the middle position of the small box is provided with the compasses, the utility model makes drawing convenient, and is favorable for management and carrying for students.
Description
Technical field
The utility model relates to and a kind of protractor, ruler, compasses is concentrated on the combination tool that one is convenient to draw.
Affiliated technical field
At present, known protractor, set square, ruler, compasses all are individualisms, very be not easy to student-directed, in mapping the time all is one by one appearance, and it is very inconvenient to use, and wherein two right angles and four acute angles of two different set squares are potentially dangerous to the student, compasses generally all are to leave in the writing case, because writing case does not have fixing position and constraint, student's compasses in motion process can be lost the screw on the leg, and make compasses ineffective.
Summary of the invention
In order to overcome the deficiency that existing protractor, set square, ruler, compasses all are individualisms, the utility model provides a kind of drawing instrument of using more, this drawing combination tool not only digests protractor, set square, ruler, compasses as a whole, and mapping is convenient, helps student's management and carries.
The technical scheme that its technical problem that solves the utility model adopts is: student's chi is designed to a two is respectively and is rectangular large tracts of land student's chi in the middle of the semicircle, on two semicircles at two, stamp the scale of protractor respectively, on rectangular two long limits, centre, stamp the length scale respectively, wherein 0 starting point of the length scale on a limit is arranged to the right from the left side, another limit 0 starting point from the centre to the both sides radiation, establish the capsule of dress compasses in the central authorities of large tracts of land student chi, establish the plastics bayonet socket of a plurality of fixedly compasses in the capsule, around capsule and in the scale on both sides, establish square, rectangle, parallelogram, equilateral triangle, the prefabricated little cavity of right angled triangle, because with protractor, set square, the function of ruler concentrates on the space of a whole page,, help student's management and carry again because thereby the middle capsule that is provided with the dress compasses makes mapping convenient.
Described drawing combination tool is plastic injection-moulded forming, and capsule and student's chi of dress compasses are as a whole.
The scale of described protractor and length scale are student's scale commonly used, wherein the length scale wherein 0 starting point of the length scale on a limit arrange to the right from the left side, another limit 0 starting point from the centre on limit to the both sides radiation.
The beneficial effects of the utility model are: because the function of protractor, set square, ruler is concentrated on the space of a whole page, thereby again because the middle capsule that is provided with the dress compasses makes mapping convenient, help student's management and carry.Since simple in structure, easy to use, be worthy to be popularized.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1. protractor a, 2. protractor b, 3 length scale a, 4. length scale b, 5.0 starting point a, 6.0 starting point b, the 7. little cavity of many kinds of shapes, 8. capsule, 9 compasses, 10. student's chi, 11. bayonet sockets.
The specific embodiment
In the drawings, protractor a (1), protractor b (2), length scale a (3), length scale b (4), 0 starting point a (5), 0 starting point b (6), student's chi (10) is formed in the little cavity (7) of multiple shape jointly, protractor a (1) wherein, protractor b (2) is at two of student's chi (10), length scale a (3), length scale b (4) is on the both sides of student's chi (10), 0 starting point a (5) is in the left side of length scale a (3), 0 starting point b (6) is in the central authorities of length scale b (4), the central authorities of capsule (8) on student's chi (10), compasses (9) are placed in the capsule (8), bayonet socket (11) and blocks compasses (9) in capsule.
Claims (3)
1. use drawing instrument one kind more, it is by protractor a (1), protractor b (2), length scale a (3), length scale b (4), 0 starting point a (5), 0 starting point b (6), the little cavity (7) of a plurality of shapes, capsule (8), compasses (9), student's chi (10), bayonet socket (11) is formed, it is characterized in that protractor a (1), protractor b (2), length scale a (3), length scale b (4), 0 starting point a (5), 0 starting point b (6), student's chi (10) is formed in the little cavity (7) of a plurality of shapes jointly, the central authorities of capsule (8) on student's chi (10), compasses (9) are placed in the capsule (8), bayonet socket (11) and blocks compasses (9) in capsule.
2. according to claim 1ly a kind ofly many use drawing instrument, it is characterized in that described many be plastic injection-moulded forming with drawing instrument, capsule and the student's chi of adorning compasses are as a whole.
3. a kind of drawing instruments of using according to claim 1 more, the scale and the length scale that it is characterized in that described protractor are student's scale commonly used, wherein the length scale wherein 0 starting point of the length scale on a limit arrange to the right from the left side, another limit 0 starting point from the centre on limit to the both sides radiation.
