Abstract
The utility model relates to an equidistant scriber for teaching, which belongs to the technical field of teaching aids. The equidistant scriber for teaching consists of a fixed plate, an extruding plate, support rods and support springs. The utility model is characterized in five circular grooves are arranged on the upper end surface of the rectangular fixed plate at equal intervals, an elastic rubber ring with the inner diameter smaller than the outer diameter of a chalk is respectively arranged on the inner wall of each groove, the five support rods sheathed with the support springs are respectively fixed on the upper end surface of the extruding plate, and the upper ends of the support rods respectively pass through through holes of the lower end surface of the fixed plate communicated with the circular grooves to be connected with a position limiting plate arranged in the circular grooves. The utility model has the advantages of simple structure and convenient use, parallel and equidistant straight lines can be drawn at the same time when teachers draw straight lines of the staff or text box type straight lines on a blackboard, the time can be saved, and the efficiency can be improved.
Description
Technical field
The utility model belongs to the teaching aid technical field, the equidistant scriber of specifically a kind of teaching.
Background technology
In the daily teaching process, when serving as a teacher on blackboard the straight line of drawing staff or Wen Geshi straight line, need draw one by one with chalk, both lost time like this, and the spacing between line and the line is difficult to again hold, operating wastes time and energy, very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of teaching that can draw parallel and equidistant straight line equidistant scriber.
The purpose of this utility model is achieved in that this teaching is made up of fixed head, stripper plate, support bar, support spring with equidistant scriber, rectangle fixed head upper surface is provided with five circular grooves equidistantly, and each groove inwall is respectively equipped with the elastic caoutchouc circle of internal diameter less than the chalk external diameter; The support bar that is with support spring above five is respectively being fixed in the stripper plate upper surface, and post upper passes respectively behind fixed head lower surface and the through hole that circular groove communicates with limiting plate in the circular groove and links to each other.
During use, can be as requested insert chalk in corresponding circular groove, utilize the elastic caoutchouc circle in the groove that chalk is carried out flexible fastening, hand is taken the fixed head equally spaced straight line that can draw on blackboard then; When changing chalk, the extruding stripper plate, limiting plate can be released the chalk head in the groove.
Advantage of the present utility model: simple in structure, easy to use, when serving as a teacher on blackboard the straight line of drawing staff or Wen Geshi straight line, the parallel and equally spaced straight line that can draw simultaneously can save time, and raises the efficiency.
