Abstract
The utility model relates to a compass with multi-leg, which is mainly composed of a level ruler, a centering rod, a plurality of sub-rods and drawing legs thereof, wherein, the centering rod is parallel with the plurality of sub-rods and is vertical with the level ruler. The compass is characterized in that the compass can draw a plurality of concentric circles once; the compass can draw a plurality of parallel lines in virtue of a straight ruler for drawing forms; scales are marked on the level ruler of the compass. The utility model has very convenient row pitch positioning and high drawing efficiency of forms or a plurality of concentric circles.
Description
The utility model belongs to cultural tools.
Existing compasses are two legs, can only be used for picture circle or draw arc, can only draw a circle or one section arc at every turn.
The purpose of this utility model is to provide a kind of Compass with multileg that once can draw a plurality of concentric circles or multistage arc and can once draw many parallel lines.
But the utility model is made up of a horizon rule by length mark, the centering bar vertical with horizon rule a branch bar and a picture leg thereof vertical with horizon bar with some and changing position.
Characteristics of the present utility model: one is to use it can once draw a plurality of concentric circles.The 2nd, once can draw many parallel lines by a ruler, can be used to draw form.The 3rd, because these compasses horizon rule has length mark, the line-spacing location is very convenient again, so picture form or draw a plurality of concentric circles high efficiency.
Below in conjunction with accompanying drawing embodiment is described:
Accompanying drawing is these compasses front view.
With reference to accompanying drawing, these compasses are made up of horizon rule (1), centering bar (5), centering pin (6), some branch bars (3), some picture legs (4 or 7), dog screws (2).Horizon rule has length mark on (1), radially screw of a flat hole and one is respectively arranged at centering bar (5) middle part and some branch bars (3) top, one axial screw is respectively arranged at centering bar (5) bottom and some branch bars (3) bottom, horizon rule (1) passes the flat hole on centering bar (5) and some the branch bars (3), each is screwed into radially screw with screw (2), and centering bar (5) and some branch bars (3) are fixed on the horizon rule (1), each minute bar with centering bar parallel and vertical with horizon rule, draw leg top for some screw thread is arranged, respectively be screwed into some branch bar lower shaft in screw, centering bar (5) axial hole is screwed into the centering leg or is screwed into the picture leg, draws leg and is equipped with lead for retractable pencil or refill for ball-point pen or duckbill paintbrush.
