Abstract
An equidistant scriber for teaching belongs to the technical field of teaching appliances. The equidistant scriber for teaching consists of a fixing plate (1), sleeves (2) and a tightening nut (3), and is characterized in that five mutually symmetrical sleeves (2), of which the internal diameters adapt to the external diameter of a chalk, are vertically and equidistantly fixed on the bottom surface of the rectangular fixing plate (1); a plurality of U-shaped nicks (4) are formed on the sleeve wall of the lower end of each sleeve (2); and the exterior of the lower end of each sleeve (2) is in threaded connection with a conical tightening nut (3). The equidistant scriber for teaching is simple in structure and easy and convenient to operate; and when a teacher draws beelines of a staff or a text format on a blackboard, parallel and equidistant beelines can be drawn out at the same time; therefore, the time is saved and the efficiency is improved.
Description
Technical field
The utility model belongs to the teaching aid technical field, and equidistant scriber is used in 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 picture with one one in chalk, so not only lose time, and the spacing between line and the line is difficult to again hold, operating wastes time and energy, very inconvenience.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, and equidistant scriber is used in the teaching of can on blackboard, draw parallel and equidistant straight line.
The purpose of the utility model is achieved in that this teaching is made up of fixed head, sleeve, clamp nut with equidistant scriber; The equidistant vertical fixing in rectangle fixed head bottom surface the sleeve that five symmetrical internal diameters adapt with the chalk external diameter respectively; Be respectively equipped with a plurality of " U " v notch v on each sleeve lower end barrel, outside, the lower end taper clamp nut that is being threaded respectively.
During use, chalk is inserted behind the sleeve fastening with clamp nut, hand is taken the fixed head equally spaced straight line that just can on blackboard, draw then.
The advantage of the utility model: simple in structure, easy and simple to handle, 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.
