Technical solutions of the utility model are achieved in that a kind of Nearsightedness-preventing pen, include the cap for brush, penholder, pen cap, nib and pen core; In penholder, be movably installed with circuit board, actuating mechanism and the battery of infrared receiving/transmission probe; Pen cap is set in penholder bottom, pen core activity is positioned in pen cap, and tegmentum is located at the nib restriction of pen cap bottom, it is characterized in that pen arm end is provided with battery tray, this battery tray vertically forms battery cavities, and battery cavities one side is provided with the polarity gathering sill of GND; Described battery cavities both sides central authorities are respectively equipped with electrode reed, and described cap for brush lid is located at pen arm end, and battery tray is wrapped up therein.

Described battery tray, by plastic shaping, is embedded at pen arm end; Described battery tray forms the cross recess that one is long and the other is short, and wherein elongated slot is battery cavities, forms polarity gathering sill in described elongated slot one side; In described short groove, be embedded with electrode reed.

The outer, end that described penholder is provided with battery tray is evenly equipped with six anti-roll salient points.

Or become the anti-roll structure of six ribs in described cap for brush outer.

Described pen core refers to refill for ball-point pen, water fillable, pen core or pencil-lead; Described pen core becomes column structure, and bottom is provided with tip of stylus; Pen core activity is positioned in pen cap, pen core upper end can be contacted by actuating mechanism and, nib exposes outside nib.

Described pen cap outer surface is evenly distributed with three depressions position that holds a pen on same circumference.

The utility model battery tray is reasonable in design, can effectively avoid pacifying battery polar anti-loaded, causes working; And battery two electrodes are organic is embedded on battery tray, without add loading electrode and wire on the cap for brush, structure and assembling are simple compared with conventional art; Moreover pen cap and nib are designed to compatible type, the exchange that can meet refill for ball-point pen, water fillable, pen core and pencil-lead is used, and realizes a multiplex secondary objective.

Detailed description of the invention:

With reference to Fig. 1, Fig. 2 and Fig. 4, Nearsightedness-preventing pen, includes the cap for brush 1, penholder 2, pen cap 3, nib 4, pen core 5, circuit board 6, actuating mechanism 7 and battery 8; On circuit board 6, be arranged on infrared receiving/transmission probe, be movably arranged on penholder 2, actuating mechanism 7 is installed in its underpart, this actuating mechanism 7 contacts in the upper end of pen core 5, and the support of pen core 5 while writing is provided; Pen cap 3 is set in penholder 2 bottoms, and pen core 5 activities are positioned over and hold a pen in 3 covers, and the nib 4 that tegmentum is located at pen cap 3 bottoms limits; Described penholder 2 upper ends are provided with battery tray 9, and this battery tray 9 vertically forms battery cavities 91, and battery cavities 91 1 sides are provided with the polarity gathering sill 92 of GND, and battery cavities 91 both sides central authorities are respectively equipped with electrode reed 93; The cap for brush 1 lid is located at penholder 2 ends, and battery tray 9 is wrapped up therein, avoids battery 8 to depart from, and opens the cap for brush 1, does not also affect the normal work of pen, and the cap for brush 1 does not play electric action, without laying electrode etc.

More particularly, battery tray 9, by plastic shaping, is embedded the upper end at penholder 2; Battery tray 9 forms the cross recess that one is long and the other is short, and wherein elongated slot is battery cavities 91, forms polarity gathering sill 92 in elongated slot one side; In short groove, be embedded with electrode reed 93, electrode reed 93 is electrically connected with circuit board 6, and working power is provided.

As Fig. 3, in order to prevent that penholder 2 from rolling, be provided with the outer, end of battery tray 9 at penholder 2, be evenly equipped with six anti-roll salient points 21; Or become the anti-roll structure of six ribs in the described cap for brush 1 outer, also can play same effect.

As Fig. 4, pen cap 3 outer surfaces are evenly distributed with three depressions position 31 that holds a pen on same circumference, and the benchmark holding a pen is provided, and help children to hold a pen highly.

As Fig. 5, be pen core picture group, pen core 5 refers to refill for ball-point pen 51, water fillable 52, pen core 53 or pencil-lead 54; 5 one-tenth column structures of pen core, bottom is provided with tip of stylus 50; Pen core 5 activities are positioned in pen cap 3, pen core 5 upper ends can be contacted by actuating mechanism 7 and, nib 50 expose nib 4 outside, be convenient to write.

For another example Fig. 1, writing process, when the infrared receiving/transmission probe of circuit board 6 detects, writer face is too low, also exceedes the critical distance of design, and circuit board 6 sends signal, actuating mechanism 7 is removed the contacting of pen core 5, and pen core 5 upper ends lose support, when nib 50 contacts paper, can inside contract toward nib 4, cannot normally write, head must recover and keep normal height, could continue to write, finally reach correction writing posture, prevent myopia.In addition, outside pen cap 3, be also equipped with a pen cap 11, to protect nib 4 and nib 50.
