Abstract
The utility model belongs to a multifunctional compass for drawing, which is composed of a handle, supporting legs, a pan head and a fixing needle. Compared with the existing compass, the utility model has the advantages of simple structure, easy fabrication and convenience for carrying, simultaneously has the functions of various stationery of straight rulers, compasses, protractors, set squares, penknives, etc., and is especially suitable for primary and middle school students.
Description
The utility model relates to a kind of drawing multifunctional compass.
At present, the compasses that people use are divided into two kinds on simple and easy compasses and Graphing of Engineering compasses, and these two kinds of compasses generally all have only the function of picture circle.Therefore, when charting, people must get all the multiple stationery such as ruler, compasses, protractor, set square, pocket knife ready, and so both inconvenient, be difficult to keeping again.
The purpose of this utility model is to provide a kind of compasses, makes it possess the function of multiple stationery such as ruler, compasses, protractor, set square, pocket knife simultaneously.
The technical solution of the utility model is: leg (3), (4) are made of the ruler of two symmetries respectively, leg (3) is the ruler of semicircular protractor for left end, semicircle center at protractor is connected with leg (4) by bearing pin, and its right-hand member is by bolt clamping nib (2); Leg (4) left end is provided with a small sircle hole, is connected with leg (3) by bearing pin, and its right-hand member is by the bolt clip locking pin; Handle (1) is sandwiched between leg (3), (4), and its ruler part straight flanges are in alignment behind leg (3), (4) flare up 180 degree.
Right-hand member between the both sides ruler of leg of the present utility model (4) is equipped with one with bearing pin can roll over the Pencil-sharpening razor blade (5) that is hidden between the ruler.
Nib of the present utility model (2) is that a centre has pin-and-hole, and all there is the double-purpose pen of nib at two.
Owing to adopted technique scheme, the utility model is compared with existing compasses, not only kept simple in structure, characteristics easy to manufacture, and possesses the function of multiple stationery such as ruler, compasses, protractor, set square, pocket knife are arranged simultaneously, be convenient to collection and carry, students in middle and primary schools are particularly adapted to.
Description of drawings:
Accompanying drawing is a concrete structure schematic diagram of the present utility model.
Embodiment:
With reference to accompanying drawing, the utility model is by handle (1), nib (2), leg (3), (4) and decide pin and form, leg (3), (4) comprise the ruler of two symmetries respectively, semicircle center at protractor is connected with leg (4) by bearing pin, its right-hand member is by bolt clamping nib (2), nib (2) is a double-purpose pen, one is propelling pencil, the other end is a ruling pen, leg (4) left end is provided with a small sircle hole, be connected with leg (3) by the bearing pin that passes small sircle hole, its right-hand member is by the bolt clip locking pin, it is sharp to decide pin two, there is one a small stair is arranged, be equipped with one with bearing pin and can roll over the Pencil-sharpening razor blade (5) that is hidden between the ruler in the position slightly left at the right-hand member of leg (4), leg (4) central design has an arc gap of being convenient to take out blade (5), and handle (1) is sandwiched in leg (3), (4) between.
