Abstract
The utility model relates to a novel chalk writing device, comprising a hollow cylinder, wherein one end of the hollow cylinder is provided with a first elastic clamping piece and a second elastic clamping piece, the first elastic clamping piece and the second elastic clamping piece are respectively externally provided with a screw thread, the first elastic clamping piece and the second elastic clamping piece are respectively externally connected with a clamping piece fixing ring by virtue of the screw threads, and the other end of the hollow cylinder is connected with a chalk propeller by virtue of a screw thread. The hollow cylinder is adopted, and chalks are placed into the hollow cylinder, thus hands can not be polluted when the novel chalk writing device is used; the first elastic clamping piece, the second elastic clamping piece and the clamping piece fixing ring are adopted, thus the chalks can be better fixed in the hollow cylinder; and the chalk propeller is adopted, thus length of each chalk in the hollow cylinder can be adjusted. The novel chalk writing device disclosed by the utility model can prevent the chalks from being broken off easily, so that cost is saved.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to a kind of chalk Write specifically.
Background technology
Chalk is the important tool of teaching usefulness, but receives the influence of manufacturing materials, exists the shortcoming of dirty hand, frangible, influences teacher's health, the waste public expense.
The utility model content
The problem that the utility model will solve is to above problem, and is hand-dirtying-free when a kind of use is provided, and the novel chalk Write of frangible not.
For addressing the above problem; The technical scheme that the utility model adopted is: the novel chalk Write comprises a hollow cylinder; One end of said hollow cylinder is provided with first elastic clip and second elastic clip; Said first elastic clip and second elastic clip are provided with screw thread outward, and said first elastic clip and the second elastic clip external screw thread are connected with the intermediate plate retainer ring, the other end of the said hollow cylinder chalk propeller that has been threaded.
The utility model is taked above technical scheme; Have the following advantages: the novel chalk Write comprises a hollow cylinder; One end of said hollow cylinder is provided with first elastic clip and second elastic clip; Said first elastic clip and second elastic clip are provided with screw thread outward, and said first elastic clip and the second elastic clip external screw thread are connected with the intermediate plate retainer ring, the other end of the said hollow cylinder chalk propeller that has been threaded; Because the setting of hollow cylinder, chalk is contained in the hollow cylinder, can dirty hand during use; Because the setting of first elastic clip, second elastic clip and intermediate plate retainer ring; Chalk better is fixed in the hollow cylinder, and the angle of rake setting of chalk can be regulated the length of chalk in hollow cylinder; This novel chalk that prevents fractures easily, has practiced thrift cost.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: the 1-hollow cylinder; 11-first elastic clip; 12-second elastic clip; The 2-screw thread; 3-intermediate plate retainer ring; 4-chalk propeller.
The specific embodiment
Embodiment: novel chalk Write; Comprise; One hollow cylinder 1, an end of said hollow cylinder 1 are provided with first elastic clip 11 and second elastic clip 12, said first elastic clip 11 and second elastic clip, the 12 outer screw threads 2 that are provided with; Said first elastic clip 11 and second elastic clip, 12 external screw threads are connected with intermediate plate retainer ring 3, the other end of the said hollow cylinder 1 chalk propeller 4 that has been threaded; Because the setting of hollow cylinder 1, chalk is contained in the hollow cylinder 1, can dirty hand during use; Because the setting of first elastic clip 11, second elastic clip 12 and intermediate plate retainer ring 3; Chalk better is fixed in the hollow cylinder 1, and the setting of chalk propeller 4 can be regulated the length of chalk in hollow cylinder 1; This novel chalk that prevents fractures easily, has practiced thrift cost.
