Abstract
The utility model provides a kind of chalk sleeve, comprises base, hollow sleeve, and it is characterized in that described base and described sleeve connection, described sleeve leading portion is provided with the hold assembly of hollow, is provided with baffle plate below described hold assembly, is provided with rubber case below described baffle plate.Described base is threaded, and sleeve bottom is with internal thread, and base by thread is connected with described hollow sleeve.Described hold assembly is elastic rubber material.Described rubber case can slide on sleeve.First base is rotated from sleeve during use and take off, again chalk is put in sleeve and screw base chalk is extruded appropriate length from clamping part, slip rubber case selects suitable position gripping to write, when chalk is finished using and is not enough to clamping, base is taken off, from clamping part chalk ejected and poured out by sleeve bottom.
Description
Technical field
The utility model relate to a kind of with chalk with the use of device.
Background technology
Along with the development of social modernization, popularizing of compulsory education, establish increasing school between urban and rural areas, the thing followed is the increase of the use amount of chalk, and present most teacher attend class use chalk be all directly grab writing on hand, the injury of the upper skin of long-term opponent is in the past very large, and writes last remaining segment chalk end and can not re-use, and causes the waste of resource.
Utility model content
In order to reduce the injury of chalk to hand skin, improving chalk utilization rate, the invention provides a kind of chalk sleeve, better
Solve the problem.Described object is achieved by the following scheme:
A kind of chalk sleeve, comprise base, hollow sleeve, it is characterized in that described base and described sleeve connection, described sleeve leading portion is provided with the hold assembly of hollow, is provided with baffle plate below described hold assembly, is provided with rubber case below described baffle plate.
Further, described base is threaded, and sleeve bottom is with internal thread, and base by thread is connected with described hollow sleeve.
Further, described hold assembly is elastic rubber material.
Further, described rubber case can slide on sleeve.
The utility model has the advantage of, manual-free can be kept away and directly grasp chalk-writing, reduce the injury of the upper skin of opponent, baffle plate can prevent chalk chip in writing process to be scattering on finger further, further minimizing is to the injury of skin, slidably rubber case on sleeve can increase the frictional force between chalk sleeve and finger, the position gripping chalk sleeve can be regulated voluntarily to increase comfort according to demands of individuals, base by thread and sleeve connection can be placed chalk better and come off from bottom, and along with chalk use shortening can extrude chalk by screwing base, resilient clamp portion can prevent the injury when extruding chalk to chalk better, save the use of chalk.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of chalk sleeve.
Detailed description of the invention
With reference to Fig. 1, the utility model provides a kind of chalk sleeve, comprises base 5, hollow sleeve 4, it is characterized in that described base 5 is connected with described sleeve 4, described sleeve 4 leading portion is provided with the hold assembly 1 of hollow, is provided with baffle plate 3 below described hold assembly 1, is provided with rubber case 2 below described baffle plate 3.Described base 5 is threaded, and with internal thread bottom sleeve 4, base 5 is connected with described hollow sleeve 4 by screw thread.Described hold assembly is elastic rubber material.Described rubber case 2 can slide on sleeve 4.First base is rotated from sleeve during use and take off, again chalk is put in sleeve and screw base chalk is extruded appropriate length from clamping part, slip rubber case selects suitable position gripping to write, when chalk is finished using and is not enough to clamping, base is taken off, from clamping part chalk ejected and poured out by sleeve bottom.
The foregoing is only preferred embodiment of the present utility model, the equal replacement that all foundation the present patent application the scope of the claims do is all within the protection domain of this patent.
