Abstract
The utility model discloses a quick drawing instrument for parallel lines, which belongs to a mathematic teaching aid, in particular to a geometric teaching aid. The utility model is characterized in that a vertical edge whose central portion is provided with a sliding groove which is parallel with an edge is arranged on the two ends of a bottom edge frame, and the vertical edge is vertical with the two ends of the bottom edge frame, a sliding mark scraper is arranged on a sliding edge with the sliding groove, conductor bars on the two end of the sliding edge are mounted in the sliding groove of the vertical edge, the sliding bars of the sliding mark scraper are mounted in the sliding groove of the sliding edge, and a pen plugging hole is arranged on the mark scraper. The utility model has simple structure, convenient employment, which is in particular applied for users to frequently drawing parallel lines which are drawn in geometric teaching or staff drawing and the like.
Description
Technical field
The utility model belongs to mathematics teaching aid, particularly the several teaching teaching aid.
Background technology
Usually need to draw parallel lines in several teaching, the common technique of painting is to pull along the parallel mobile another side line of using pen at set square of a ruler with a triangle, and it is loaded down with trivial details to operate like this, and particularly setting-out is inconvenient more on vertical blackboard.
The utility model content
The purpose of this utility model provides a kind of technical scheme of the parallel lines quick drawing device that can draw parallel lines fast easily.
The technical solution of the utility model is, a kind of parallel lines quick drawing device, it is characterized in that: the vertical edges that there is the sliding tray parallel with the limit at perpendicular middle part is equipped with at the boundary frame area two ends, on the slip limit of band sliding tray the slip scriber is housed, the guide post at two ends, slip limit is installed in the vertical edges sliding tray, the sliding bar of slip scriber is installed in the sliding tray on slip limit, and pen plughole is arranged on the scriber.
The parallel lines quick drawing device that the utility model provides, easy to use, only need place it on the plane that needs line with article one straight line that draws along the slip limit of the pen in the pen plughole, certain distance second line that draws is again moved on promotion slip limit, two lines are parallel lines, and many parallel lines equally can draw.This parallel lines quick drawing device has simple in structure easy to use, is particularly suitable for user's use that several teaching and picture staff etc. need often draw parallel lines.
