Abstract

The utility model relates to a multifunctional chalk sleeve. The multifunctional chalk sleeve comprises a chalk sleeve body and springs. The front end face of the chalk sleeve body is provided with five small holes with diameter slightly greater than chalks side by side. The open ends of the small holes are used for installing the chalks. The bottom of each small hole is provided with a spring, and the springs installed inside the small holes closely contact with the chalks. The chalk sleeve body can be provided with a hand shank, and the hand shank can be in an integrated shape with the main body of the chalk sleeve body. The material of the chalk sleeve body preferably is woodiness and can also be else materials, and the material of the springs preferably is iron. The five small holes of the chalk sleeve body are all provided with the chalks and the lengths of the chalks are roughly equal, or only the two end holes are provided with the chalks. The multifunctional chalk sleeve is easy to manufacture and convenient to use, and a spring telescopic structure can enable the five chalks simultaneously leave clear marks on a blackboard. Therefore, patterns such as parallel lines, circles, various quadrilaterals and musical notations can be rapidly and orderly depicted on the blackboard.

Description

A kind of multi-function chalk casing
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of multi-function chalk casing.
Background technology
Now the mathematics teacher to draw parallel lines on class, draw circle, draw the figures such as various quadrangles all be to describe conveniently with piece of chalk, waste time and energy and not attractive in appearance, and Music Teacher's picture staff of giving a lesson to be carried the dedicated small blackboard of having finished five lines, extremely inconvenient.Therefore, how drawing these on the classroom must figure be that instructors is urgently wished the problem that solves quick, neat, attractive in appearancely.
The utility model content
The technical problems to be solved in the utility model is that a kind of multi-function chalk casing that can paint fast figure on blackboard and make figure energy neat appearance is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: described multi-function chalk casing comprises chalk sleeve body, spring, the front end of described chalk sleeve body is provided with five slightly larger in diameter side by side in the aperture of chalk, and the openend of each aperture is used for that chalk is installed, the bottom arranges a spring.
Described chalk sleeve body can be with handle, and handle can be integrally formed with the main part of chalk sleeve body.The material of described chalk sleeve body is preferably wooden, also can be other materials.The preferred irony of described spring.The length of chalk and chalk all is installed in five apertures of described chalk sleeve body in the aperture of two, chalk is installed about equally or only.
The utility model is made easily, and is easy to use, and the telescopic spring structure can make five chalks stay clear vestige at blackboard simultaneously.The present invention makes the teacher " one is come " solve a difficult problem of fast, neatly drawing the figures such as parallel lines, circle, various quadrangle, staff on the blackboard, is expected to become the good assistant of the course class-teaching of teachers such as mathematics, music, physics.
Description of drawings
Fig. 1 is longitudinal sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, the first embodiment of the present utility model is that described multi-function chalk casing comprises wood powder pen cap body 1, the spring 2 with handle 4, the front end face of described chalk sleeve body 1 is provided with five slightly larger in diameter side by side in the aperture 3 of chalk, each aperture 3 bottom arranges a spring 2, chalk be installed in five apertures 3 openend and with spring 2 close contacts.Described handle 4 is integrally formed with the main part of chalk sleeve body 1.The material of described chalk sleeve body 1 also can be other materials, and the material of described spring 2 is irony or other materials.Be installed in the length of five chalks in the aperture 3 about equally.During use, the teacher holds teaching aid handle 4, once draws five parallel lines on blackboard, is used for five line music score.
The place that the second embodiment of the present utility model is different from the first embodiment only is only in two aperture 3 chalk to be installed in five apertures 3 of described chalk sleeve body 1.Can on blackboard, once draw two parallel lines, change again a direction and once draw in addition two parallel lines, just can draw the quadrangle of a rule; Also can be take a chalk as the center of circle, circle of other end chalk rotary picture.
The utility model is made easily, and is easy to use, and spring 2 stretching structures can make five chalks stay clear vestige at blackboard simultaneously.The present invention makes the teacher " one is come " solve a difficult problem of fast, neatly drawing the figures such as parallel lines, circle, various quadrangle, staff on the blackboard, is expected to become the good assistant of the course class-teaching of teachers such as mathematics, music, physics.
