Abstract

The utility model discloses a chalk holder which can effectively solve the problem that a hand is contaminated by dust in the process of writing by using chalks. The chalk holder comprises two clamping pieces, wherein the working surface of each clamping piece is provided with a semicircular groove, and the radius of the semicircular groove is equal to the radius of a chalk; the two sides of each clamping piece are respectively provided with an articulated tooth along the axial direction of the semicircular groove, and the articulated teeth of the two clamping pieces are provided with magnets; and the articulated teeth of the two clamping pieces are articulated in a staggered adsorption mode through the magnets. The chalk holder disclosed by the utility model is used for isolating fingers from dust pollution; moreover, the chalk holder also as an ornament can be sleeved at the upper end of a pencil or a neutral pen, and the weight of the upper end of the pencil or the neutral pen is also increased, so that character fonts written by using the pencil or the neutral pen are more tasteful and beautiful, therefore, the chalk holder is suitable to be used by teachers and students.

Description

A kind of chalk sleeve

Technical field

The utility model relates to a kind of device that holds chalk.

Background technology

Existing nowadays in school, chalk remains requisite realia, yet when writing writing on the blackboard usually; Because finger contacts with chalk, can speckle with dust unavoidably on finger and the palm, these dust are stayed on hand; Be difficult for to clean, teacher's health caused healthy hidden danger on the other hand, when chalk used very short after; Hold owing to be difficult for taking, will they be lost, cause waste.

The utility model content

The purpose of the utility model is to provide a kind of chalk sleeve, is infected with the problem of dust when this chalk sleeve can effectively solve and write with chalk on hand.

The utility model solves the technical scheme that its technical problem adopted: a kind of chalk sleeve, comprise two intermediate plates, and the working face of each intermediate plate is equipped with semi-circular grooves, and the radius of said semi-circular grooves equals the radius of chalk; On the dual-side of said intermediate plate, be provided with tooth engaged along the axial of semi-circular grooves, and the tooth engaged of two intermediate plates is provided with magnet; The tooth engaged of two intermediate plates is through the staggered absorption of described magnet interlock.

The utlity model has following outstanding beneficial effect:

1, this project organization is simple, and is convenient and practical, not only can be used as chalk sleeve; Be used for isolating the pollution that the dust adversary refers to; Can also be nested with upper end at pencil or gel ink pen as ornament, increase the upper end weight of pencil or gel ink pen again simultaneously, thereby make the font of writing out more sedate beautiful.

2, the design of tooth engaged and magnet, it is tightr that the jacket casing body is combined.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1 intermediate plate, 11 semi-circular grooves, 2 tooth engaged, 3 magnet.

The specific embodiment

As shown in Figure 1.This chalk sleeve comprises two intermediate plates 1, and the working face of each intermediate plate 1 is equipped with semi-circular grooves 11, and the radius of said semi-circular grooves 11 equals the radius of chalk; On the dual-side of said intermediate plate 1, be provided with tooth engaged 2 along the axial of semi-circular grooves 11, and the tooth engaged 2 of two intermediate plates is provided with magnet 3; The tooth engaged 2 of two intermediate plates is through described magnet 3 staggered absorption interlocks.

During as chalk sleeve,, on chalk, select a suitable impetus,, impetus one section chalk up and down is nested with between the semi-circular grooves of two intermediate plates 1 through the interlock of tooth engaged 2 and the absorption of magnet 3 according to individual's writing style.

Also can be nested with identical method, increase the upper end weight of pencil or gel ink pen, thereby make the font of writing out more sedate beautiful on the top of pencil or gel ink pen.

The intermediate plate outer surface can be drawn different pattern, increases attractive in appearance.

Claims

1. chalk sleeve, it is characterized in that: comprise two intermediate plates, the working face of each intermediate plate is equipped with semi-circular grooves, and the radius of said semi-circular grooves equals the radius of chalk; On the dual-side of said intermediate plate, be provided with tooth engaged along the axial of semi-circular grooves, and the tooth engaged of two intermediate plates is provided with magnet; The tooth engaged of two intermediate plates is through the staggered absorption of described magnet interlock.
