A plurality of round holes are arranged on the wooden box, the diameter of each round hole is the same as that of a piece of chalk, and the height of the wooden box is two thirds of the length of the chalk. By adopting the scriber for the blackboard, the benefits are as follows: a plurality of parallel straight lines can be drawn by moving the scriber of a teacher at one time, the speed is quick, the time is saved, and the teaching efficiency is also improved.
Description
Technical field:
The utility model relates to a kind of teaching aid.
Background technology:
Teacher teaches on the classroom, all will use chalk, also often need draw straight line on blackboard.So teacher will inevitably be with a long wooden rule on class, so that draw the usefulness of straight line, and need how many root straight lines of picture, must use how many vice-minister's wooden rules.This action not only bothers, and has consumed the teaching time.
Summary of the invention:
The purpose of this utility model is that a kind of blackboard scriber will be provided, and the blackboard scriber is a strip wood casket, establishes a plurality of circular holes above the wooden casket, and the diameter of circular hole is identical with the chalk diameter, and the height of wooden casket is 2/3 of a chalk length.
During use, chalk is inserted in the wooden casket circular hole of blackboard scriber,, and make the chalk head, laterally move wooden casket in the position that needs the picture straight line, then many parallel straight lines can on blackboard, occur towards the blackboard surface with the ash-pit that connects of wooden casket setting against the blackboard below; And the spacing of parallel lines can by chalk placement location decide.So teacher uses the blackboard scriber, move many parallel lines of once just can drawing, seeming saves time fast, has also improved teaching efficient.
The blackboard scriber is a strip wood casket, establishes a plurality of circular holes above the wooden casket, and the diameter of circular hole is identical with the chalk diameter, and the height of wooden casket is 2/3 of a chalk length.
Adopting the beneficial effect of blackboard scriber is that teacher uses the blackboard scriber, moves many parallel lines of once just can drawing, and seeming saves time fast, has also improved teaching efficient.
Description of drawings:
Fig. 1 is the structural representation of blackboard scriber.
The specific embodiment:
With reference to Fig. 1, the blackboard scriber is a strip wood casket 1, establishes a plurality of circular holes 2 above the wooden casket 1, and the diameter of circular hole 2 is identical with the chalk diameter, and the height of wooden casket 1 is 2/3 of a chalk length.
