Description
Technical field
The utility model belongs to wax crayon or chalk clamper, particularly a kind of chalk overcoat.
Background technology
Chalk is the writing implement that the teacher uses always, but its shortcoming is unhygienic, and chalk dust is stained with and is not easy to hand to clean.The innovation and creation that on March 4th, 2009, disclosed application number was 200820120530.X disclose a kind of chalk sleeve.This chalk sleeve opens two grooves over against both sides and an end is the opening shape, and two limits are provided with limiting tooth in the groove, and the chalk folder is positioned at chalk protective sleeve and chalk folder group ear and chalk protective sleeve two grooves couplings over against both sides.The shortcoming of this chalk sleeve is more loaded down with trivial details the operation of chalk release chalk sleeve, and in the process of releasing chalk chalk sleeve, chalk is fractureed.The innovation and creation that on June 22nd, 2011, disclosed application number was 201020657701.X disclose a kind of chalk sleeve.This chalk sleeve comprises the body of both ends open, and the cross section of body is consistent with the cross section of chalk, and the bottom opening of body is slightly larger than the chalk diameter.This chalk sleeve is a cone shape, and the opening of an end is suitable with the chalk diameter, can chalk sleeve be enclosed within on the chalk, when writing, arrests the pen cap with hand like this and gets final product.But this chalk sleeve is because the cross section of body is consistent with the cross section of chalk, and in fact chalk is not easy from this chalk sleeve, to extrude.
The utility model content
The purpose of the utility model provides a kind of chalk overcoat, and this chalk overcoat is convenient to be released chalk or the income pen cap.
The scheme that the utility model solve the technical problem is: a kind of chalk overcoat, comprise the pen cap, and it also comprises support column and rotor, and support column comprises bottom and arc support chip, and the arc support chip is positioned at the pen cap, and rotor is positioned on the arc support chip; On the inwall of the said pen cap spiral lamination is set, the outer surface setting of rotor and the external screw thread that spiral lamination is complementary.
During use, insert chalk in the chalk overcoat, the bottom of chalk props up rotor, and the side of chalk leans against on the support chip, prevents that chalk from use rupturing.The bottom of rotational support post, rotor can rise or descend along the spiral lamination on the pen cap inwall, thereby realizes releasing or take in the function in the pen cap to chalk.
As further technical scheme, the length of said arc support chip and the equal in length of the pen cap.
This technical scheme can make chalk use the bottom always and be not wasted.
As further technical scheme again, the outer surface of the said pen cap is provided with anti-skidding line.
After the outer surface of the pen cap was provided with anti-skidding line, the user can not cause the landing of chalk overcoat because hand is perspired.
In sum, the utlity model has simple in structure, easy to operate advantage.
