Description
Technical field
The utility model belongs to the schooling apparatus technical field, particularly relates to a kind of pencil sharpener with automatic prompting function.
Background technology
Teacher need to use chalk to write the content of courses at blackboard at school the time, in said process, can frequently there be chalk powder to fall down from chalk, most of chalk powder can drop in the ledge for chalk on blackboard, but still has small part to descend slowly and lightly in the classroom with flowing of air-flow.As everyone knows, suck chalk powder health is caused harmful effect, but the measure that does not effectively address this problem at present.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of pencil sharpener with automatic prompting function.
In order to achieve the above object, the pencil sharpener with automatic prompting function that provides of the utility model comprises main body, pencil sharpener, indicating bar, rotating shaft, spring and wood chip box; Wherein main body is box-like, and the left side, upper surface is formed with a strip opening along left and right directions; The lower end of spring is fixed on the main body bottom surface that is positioned at the opening below; Indicating bar vertically runs through and is arranged in the opening, and the middle part is formed with a perforate, and the lower end links to each other with the upper end of spring; The perforate at indicating bar middle part is run through at the middle part of rotating shaft, and two ends are connected on the rear and front end face of main body; Pencil sharpener is installed in the upper right of main body, and the pencil exit face on it is to indicating bar; The wood chip box is drawer-like, is located at the body interior that is positioned at the pencil sharpener bottom in mode that can move left and right.
Described spring is helical spring.
The pencil sharpener with automatic prompting function that the utility model provides can be realized the function whether the automatic-prompting pencil fines away, and it had both kept small and exquisite, the simple characteristics of portable pencil sharpener, had avoided again waste.Because it is simple in structure, need not to increase too many cost, and easy to operate, the operator need not can use through the study of complexity.
Description of drawings
The pencil sharpener structural representation with automatic prompting function that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the pencil sharpener with automatic prompting function that the utility model provides is elaborated.
As shown in Figure 1, the pencil sharpener with automatic prompting function that provides of the utility model comprises main body 1, pencil sharpener 2, indicating bar 3, rotating shaft 4, spring 5 and wood chip box 6; Wherein main body 1 is box-like, and the left side, upper surface is formed with a strip opening 7 along left and right directions; The lower end of spring 5 is fixed on main body 1 bottom surface that is positioned at opening 7 belows; Indicating bar 3 vertically runs through and is arranged in the opening 7, and the middle part is formed with a perforate, and the lower end links to each other with the upper end of spring 5; The perforate at indicating bar 3 middle parts is run through at the middle part of rotating shaft 4, and two ends are connected on the rear and front end face of main body 1; Pencil sharpener 2 is installed in the upper right of main body 1, and the pencil exit face on it is to indicating bar 3; Wood chip box 6 is drawer-like, is located at main body 1 inside that is positioned at pencil sharpener 2 bottoms in mode that can move left and right.
Described spring 5 is helical spring.
The pencil sharpener course of work with automatic prompting function that now the utility model is provided describes: during use, at first the end with pencil inserts from the pencil porch of pencil sharpener 2 outer ends, then rotation pencil, in this process, pen tip position constantly advances to the pencil outlet, after pencil is fined away, nib can stretch out from the pencil outlet, when treating that nib touches the top of indicating bar 3, it will promote the top of indicating bar 3 left, and the lower rightward of indicating bar 3 is swung, after nib reaches certain-length, indicating bar 3 lower ends will outwards promote wood chip box 6, thus wood chip box 6 be released outside the main body 1, show that this moment, pencil was cut, the user can extract pencil out from pencil sharpener 2, and the scrap in the wood chip box 6 poured out, then it is back in the main body 1, thereby with the bottom pushed home of indicating bar 3.
