Abstract
The utility model relates to an improved anti-close-distance pen point. A pen core sleeve (1) and a taper semicircle sleeve (4) are fixedly connected by a spring steel wire (3); the contacting point (6) of the pen core sleeve (1) and the taper semicircular sleeve (4) is used as a supporting point, so as to form a lever structure, shown in the specification 4. The writing or non writing is controlled by the distance of the pen holding in the utility model, so that the distance of pen holding when the pupils write can be efficiently controlled, which makes the pupils have a good writing habit, and can prevent the short sight.
Description
The utility model is the improvement about pencil stub, is that a kind of pupil of being used for writes the hold a pen nib of distance of time control.
The pupil begins to learn when writing, and often can not correctly control the distance that holds a pen, and is difficult for forming good writing style, and this is the individual key factor that causes myopia.
In order to address this problem, existing all is by pointed out the student with color or shape on nib.But this in practice the pupil be difficult for remembeing.
The purpose of this utility model is: a kind of improved nib is provided.It can control the distance that holds a pen effectively.
The scheme of its solution is: firmly be connected with the most advanced and sophisticated of tapering semicircle cover with the small end of spring steel wire with the pencil lead cover, make it to form lever construction.Like this, when holding tapering semicircle set upper side, just open its lower end, and pencil lead is loosening, can not write; After hand left, spring steel wire can recover the tapering semicircle cover clamping pencil lead that resets to write.
Accompanying drawing has been described an embodiment of the present utility model, and accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3 are component diagram, and accompanying drawing 4 is overall diagrammatic sketch.
To firmly connect in the hole (2) in the end insertion accompanying drawing 1 pencil lead cover (1) of accompanying drawing 2 medi-spring steel wires (3); And firmly connect in the hole (5) on the tip of the other end of spring steel wire (3) insertion accompanying drawing 3 tapering semicircle covers (4).This moment, the left side of pencil lead assembled, and the assembling and the left side on its right are identical.
Shown in accompanying drawing 4: pencil lead cover (1) is connected by spring steel wire (3) with tapering semicircle cover (4).Its contact point (6) becomes fulcrum, thereby has formed lever construction.When writing, when the upper end held at tapering semicircle cover (4), its lower end will be opened, and pencil lead promptly gets loose, so can not write; After hand left tapering semicircle cover (4), spring steel wire (3) made the lower end of tapering semicircle cover (4) the clamping pencil lead that resets, so can recover normally to write.
When if the power of spring steel wire (3) is not enough, also can add a untight turn in the most advanced and sophisticated periphery of nib increases the strength that resets.
Claims (1)
1, a kind of anti-low coverage nib by spring steel wire, pencil lead cover and the assembling of tapering semicircle cover, it is characterized in that: pencil lead cover (1) is connected to form lever construction with tapering semicircle cover (4) by spring steel wire (3); Tapering semicircle cover (4) relies on the elastic reset of spring steel wire (3) to clamp pencil lead.
