Abstract
Belonging to school supply and stationery, is to be provided with two rulers in the bipod inboard of compasses, and there is the everyday character motherboard in the outside, and top is provided with protractor, shows gusset, magnifying glass and making.Rotate bipod, show that the limit of gusset can show the two chi angles of cut on protractor, do the tolerance angle and use.30 °, 45 °, 60 °, the 90 ° available dog screws in special angle, cave, location come pin fixed, make two chis become each angle of set square.Two chi angles still can go to 180 ° and become a ruler, and the numeral of ruler and outside letter commonly used is the empty word body and can retouches word usefulness, makes this instrument have compasses, protractor, set square, ruler, magnifying glass, retouches six functions of character matrix plate.
Description
The present invention a kind ofly has compasses, protractor, set square, ruler, magnifying glass and retouches the improved drawing compasses with six functions of character matrix plate function.
Existing drawing appliance has only the protractor mint-mark on set square, or ruler and protractor, retouch character matrix plate and carve or be imprinted on the transparent panel, not seeing has these instruments and combined data and the material object of compasses generation both at home and abroad.
The present invention will and retouch six multifunctional student stationery of character matrix plate compasses, protractor, ruler, set square, magnifying glass.
The present invention is that the upper end branch in compasses bipod (1), (2) is provided with protractor (11) and shows gusset (7).On protractor, be furnished with cave (10), location, showing that design has dog screw (8), bundle of spheres (9) and magnifying glass (6) on the gusset, two jiaos of inboards are respectively equipped with left chi (3), right chi (4), bipod (1), (2) and are connected in the rotating shaft (12), and can rotate in the above.Rotating shaft (12) design is on the extended line on two chi limits.Right crus of diaphragm (2) top is bent upwards and forms side opening (5) with right chi top.Rotate bipod, be screwed into dog screw (8), can insert each hole, cave (10), location respectively, then two chi angles can be locked into 30 °, 45 °, 60 °, 90 ° and can make set square and use.Unclamp dog screw (8) and rotate bipod, the angle of two chis (3), (4) can illustrate the number of degrees by the side that shows angle (7) on protractor, and these just available two chi angles take measurement of an angle, and makes protractor and uses.Two chis are forwarded to 180 degree, at this moment can make ruler and use.This instrument has three layers at thickness direction: two chis (3), (4) are bottom, and left foot (1) (comprising protractor), right crus of diaphragm (2) bottom and side opening (5) are the middle level, and right crus of diaphragm (2) top (comprise and show gusset) is the upper strata.The top of protractor can be inserted in the side opening (5) when therefore rotating bipod, makes two chis can reach 180 degree angles, becomes a ruler.When bundle of spheres (9) can make this instrument do the compasses use, realize horizontal rotation, handled easily.
The numeral of letter commonly used that is furnished with in two outsides of bipod and left chi, right chi is the empty word body, forms and retouches character matrix plate.
This instrument has been realized compasses, protractor, set square, ruler, magnifying glass, has been retouched the character matrix plate integrator, reaches manufacturing, carries, uses, deposits the four directions just.
(1) left foot, (2) right crus of diaphragm, (3) left chi, (4) right chi, (5) side opening, (6) magnifying glass, (7) show gusset, (8) dog screw, (9) bundle of spheres, cave, (10) location, (11) protractor, (12) rotating shaft, (13) template in the accompanying drawing.
Claims (6)
1, a kind of improved drawing compasses with six functions is characterized in that: each side is provided with the semicircular protractor (11) that becomes rigid connection respectively with the compasses bipod and shows gusset (7) in the compasses upper end.The bipod inboard is provided with two rulers (3), (4), and compasses rotating shaft (12) is arranged on the extended line on two chi limits, and therefore, two chi angles just can show on protractor by the one side that shows gusset.
2, the described improved drawing compasses with six functions of claim 1, it is characterized in that showing that design has dog screw on the gusset, protractor is provided with cave, four location, and dog screw can lock in two chi limits 30 °, 45 ° 60 °, 90 ° position.Two chi angles just become each horn shape attitude of set square.
3, the described improved drawing compasses with six functions of claim 1, it is characterized in that thickness direction becomes three-decker, two chis (3), (4) are bottom, the latter half of left foot (1), protractor (11), right crus of diaphragm (2), and side opening (5) is the middle level, right crus of diaphragm (2) the first half and show that gusset is the upper strata, have on the right crus of diaphragm (2) and can allow protractor rotate the side opening (5) that insert the back, and be designed to make the two chi angles of cut to pass on 180 degree, become a ruler state
4, the described improved drawing compasses with six functions of claim 1 is characterized in that the handle (9) of compasses is designed to ball, is disposed at and shows the gusset top, and behind the extended line that departs from the chi limit-angle.
5, the described improved drawing compasses with six functions of claim 1 is characterized in that the upper end of compasses is provided with magnifying glass.
6, the described improved drawing compasses with six functions of claim 1, the numeral that it is characterized in that the letter commonly used that is furnished with on the compasses and chi are the empty word body and constitute and retouch character matrix plate.
