Technical field

The utility model relates to stationery, relates in particular to a kind of automatic honorarium chalk sleeve.

Background technology

Chalk is the indispensable articles for use of teaching field; Numerous for a long time teachers directly write on blackboard with holding chalk; It is unfavorable that the chalk that contains chemical analysis brings the skin of staff; Simultaneously also very unhygienic, the respiratory system that the chalk powder that produces when writing gets into the people also has great harm to health; Easily broken and the discarded length of chalk is long, and its utilization rate is lower, and waste is serious.This situation is the long-standing problem of current culture and education system.

The utility model content

In order to solve the existing problem in above-mentioned culture and education field; The utility model provides a kind of can regulate chalk writing part length easily; Make chalk can not account for dirty staff, prevent the automatic honorarium chalk sleeve that easily broken and discarded length is long and the moistening chalk of ability is exempted from green powder of chalk.

The purpose of the utility model is achieved in that a kind of automatic honorarium chalk sleeve that comprises pen cap body, pen cap core, spring, pen cap body end cap, liquid capsule, catheter, honorarium hole; It is characterized in that being arranged on the hollow pen cap core in the pen cap body; There is semi-circular button the upper end of pen cap core, is provided with bulge loop below the button; The lower end of pen cap core is provided with the degree of tightness dop, has done the honorarium hole on the card base of degree of tightness dop.Spring housing is on pen cap core, and the one of which end bearing is on the bulge loop at pen cap core middle part, and the other end is bearing on the bulge loop of pen cap body end cap, and the liquid capsule is arranged in the button, is connected through the honorarium hole on the card base of catheter and degree of tightness dop.During use, press the button, pen cap core moves to its degree of tightness dop direction; Make the degree of tightness dop stretch out pen cap body end cap; Insert chalk in the middle of the degree of tightness dop and adjust length, release button, pen cap core contract under the effect of spring chalk are blocked; It is moistening that light hydraulic fluid capsule uses the liquid in the liquid capsule that chalk is carried out, and this liquid is alcohol.Chalk is carried out moistening back just can have been write.When needing adjustment chalk length; The degree of tightness dop presses the button from the desktop certain altitude downwards; Pen cap core moves to its degree of tightness dop direction; Make the degree of tightness dop stretch out pen cap body end cap and unclamp chalk, chalk skids off in the middle of the degree of tightness dop under the gravity effect, can adjust chalk writing part length easily.The automatic honorarium chalk sleeve of above-mentioned characteristic can be adjusted chalk writing part length easily, makes chalk can not account for dirty staff and can exempt from green powder by moistening chalk, and the respiratory system of avoiding the chalk powder to get into the people causes great harm to health; Also prevent the generation of the long phenomenon of easily broken and discarded length of chalk.
