Abstract
The invention has a wear-resistant triangle, which comprises a triangle. Each side of the triangle is provided with a length scale; three sides of the triangle are provided with through holes; two sides of each through hole are connected with two ends of a support through springs; the middle of the support is provided with a horizontal rod which is inserted into a center hole of a ball; and the lower end of the ball extends out of the lower opening of the support. The wear-resistant triangle is convenient to use and reasonable in design, can avoid wearing a drawing due to repeated movement during drawing, and keeps paper clear and tide.
Description
Technical field
The present invention relates to a kind of drawing instrument.
Background technology
People often use set square when drawing, in the process of drawing, usually need to drag back and forth the chi body on paper, because drawing adopts pencil to draw, drag the vestige that can streak pencil, and drawing is made dirty even be fuzzy clearly easily.
Summary of the invention
The purpose of this invention is to provide a kind of easy to usely, be convenient to keep the clear clean and tidy anti-wear set square of drawing.
The present invention includes set square, each limit of set square is equipped with the length scale, and place, set square three limits is equipped with through hole; The through hole both sides are connected with the support two ends through spring; Mid-stent is provided with the horizontal body of rod, and the horizontal body of rod is plugged on the ball centre bore, and stretch out from the support lower ending opening ball lower end.
When dragging set square, ball is propped set square, makes itself and paper keep certain distance; Ball streaks drawing when dragging like this; Set square can not contact paper, reduces the wearing and tearing to drawing, during drawing; Push set square downwards; Ball moved up and drove support and move to the through hole top this moment, and set square is close to paper, after loosing one's grip; Spring recovers deformation, and ball stretches out through hole.
The present invention compared with prior art has following advantage: easy to use, reasonable in design, and move around in the time of can avoiding drawing drawing is caused wearing and tearing, be convenient to keep drawing clear clean and tidy.
Description of drawingsFig. 1 is a stereochemical structure sketch of the present invention.
