Abstract
The utility model relates to a kind of mechanical pencil that automatically can regulate pen holding posture, described mechanical pencil comprises penholder and plastic bar, described plastic bar is hingedly coupled to penholder, when holding a pen, plastic bar contacts with inside palm, penholder is also provided with small-sized angular transducer, plastic bar and penholder angulation θ when holding a pen for measuring, described angular transducer connects indicator lamp, described indicator lamp is in being arranged on mechanical pencil penholder top, as 30 ° of < θ < 90 °, indicator lamp does not work, when θ is other angle, the indicator lamp arranged at the top of pen is lighted.The outer wall of pen is also provided with push switch, and described indicator lamp, angular transducer is electrically connected with switch.The utility model has the advantage of the incorrect pen holding posture of prompting pupil and the dynamics that holds a pen in time.
Description
Technical field
The utility model belongs to field of stationery, especially a kind of pen that automatically can regulate pen holding posture.
Background technology
When pupil has just practised writing, often because pen holding posture is not right, firmly excessive when causing writing, due to long incorrect pen holding posture, the forefinger of pupil and thumb can be made to produce distortion.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the mechanical pencil that correctly can regulate pen holding posture that a kind of structure is simple, reasonable in design, easy to use.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of mechanical pencil that automatically can regulate pen holding posture, it is characterized in that: described mechanical pencil comprises penholder and plastic bar, described plastic bar is hingedly coupled to penholder, when holding a pen, plastic bar contacts with inside palm, penholder is also provided with small-sized angular transducer, plastic bar and penholder angulation θ when holding a pen for measuring, described angular transducer connects indicator lamp, described indicator lamp is in being arranged on mechanical pencil penholder top, as 30 ° of < θ < 90 °, indicator lamp does not work, when θ is other angle, the indicator lamp arranged at the top of pen is lighted.The outer wall of pen is provided with push switch, and described indicator lamp, angular transducer is electrically connected with switch.
And be provided with two depressed parts corresponding with thumb and forefinger in the bottom of penholder, depressed part bottom is connected with small-sized pressure sensor, and when the dynamics of holding a pen is greater than 30N, indicator lamp is lighted.
Advantage of the present utility model and good effect are:
The utility model can point out the incorrect pen holding posture of pupil and the dynamics that holds a pen in time.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model
Detailed description of the invention
