Abstract

The utility model provides a twin core pencil compass. The improvement thereof is that a main leg of a compass is fixed with single head compass needle feet and double head lead core feet, the end head of the single head compass needle feet is fixed with compass needles, both end heads of the double head lead core feet are fixed with thick and thin lead cores, compass sub-legs are fixed with compass sub-feet, one end head is fixed with compass needles through a clip piece, and the other end head is fixed with a drawing pen with a screw nut. The utility model is not only provided with the various functions of an ordinary compass, but also can draw big and small arcs and equant line segments and can displace the line segments, and can draw arc lines with different thickness in hand-drawing. The utility model has the advantages of extreme convenience and combination of multiple functions, and removes the inconvenience which is caused by the assembly of a suite compass and the trouble of the simultaneous using of two or three compasses.

Description

Twin core pencil compasses
Technical field
The utility model relates to a kind of study, drawing appliance, the particularly a kind of combined type Twin core pencil compasses that can draw the different circular arcs of thickness.
Background technology
The compasses that use in existing study, the drawing, draw two kinds of different circular arc line drafts of thickness and circular arc, paint large size circular arc, five equilibrium, dislocation line segment etc., must dismounting use the external member compasses or use two or three compasses just can finish simultaneously, this not only loses time but also inconvenient, I am in the study drawing course, want on the basis of existing compasses, on the rule pin, set up the fixedly device of different thicknesses lead for retractable pencil again, and can be fixing flexibly by fixture, when using the thickness setting-out, can change fixing the use mutually.Thereby designed a kind of Twin core pencil compasses.
Summary of the invention
The purpose of this utility model provides a kind of Twin core pencil compasses, mainly solves existing compasses single gauge pin and is drawing bowlder, the problem of two kinds of lines of the thickness of can not drawing.
The utility model will realize that the technical scheme that above-mentioned purpose is taked comprises slip teeth, cross mouth screw, compasses master leg, ruling pen, nut, compasses straddle, intermediate plate, cap bag, rule pin, thickness lead for retractable pencil, single head rule stitch, double end lead for retractable pencil pin, its improvement is by fixed by nut single head rule stitch and double end lead for retractable pencil pin are arranged on the compasses master pin, and be fixed with the rule pin by cap bag in the termination of single head rule stitch, be fixed with the thickness lead for retractable pencil in the two ends of double end lead for retractable pencil pin by cap bag; Have compasses to divide pin by fixed by nut in the compasses straddle, and at one end head is fixed with the rule pin by nut by intermediate plate, the other end has ruling pen by fixed by nut.
The utility model is implemented advantage that technique scheme brings and good effect and is by to fixing two kinds of different fixtures of thickness on two rule pin of existing compasses, can realize above-mentioned purpose, these compasses not only possess the various functions of common compasses, and can draw big or small circular arc, five equilibrium line segment, dislocation line segment, can also draw out the circular arc line that thickness is different in the hand-drawing comes, this is for using thin circular arc in the draft, retouching the hand-drawing that uses thick circular arc in the shape, and is very convenient.That this practicality newly collects is multi-functional in together, has removed that the external member compasses need be assembled from and inconvenience and two or three trouble that compasses use simultaneously of bringing.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing or embodiment, and present embodiment is to explanation of the present utility model, the utility model is not done any qualification.
Twin core pencil compasses is the improvement on the basis of existing compasses, its improvement is to go up by nut (5) at compasses master pin (3) to be fixed with single head rule stitch (11) and double end lead for retractable pencil pin (12), and be fixed with rule pin (9) by cap bag (8) in the termination of single head rule stitch (11), be fixed with thickness lead for retractable pencil (10) in the two ends of double end lead for retractable pencil pin (12) by cap bag (8); Upward being fixed with compasses by nut (5) divides pin (13) in compasses straddle (6), and at one end head is fixed with rule pin (9) by nut (5) by intermediate plate (7), and the other end is fixed with ruling pen (4) by nut (5).
During use, the slip teeth (1) on compasses bipod top is fixed on the ungulate steel disc by two cross mouth screws (2), compasses single head rule stitch (11) and double end lead for retractable pencil pin (12) are by nut (5) and screw is overlapping is fixed on the compasses master leg (3), rotating screw cap (5) can make compasses single head rule stitch (11) and double end lead for retractable pencil pin (12) rotate, thereby satisfies the drawing requirement.Ruling pen (4) is regulated by nut (5), and the intermediate plate (7) of fixed gauge pin (9) is regulated by nut (5), and thickness lead for retractable pencil (10) is fixed on the compass leg by cap bag (8).
