Description

Ball pen safe in utilization

Technical field

The utility model relates to a kind of stationery, particularly a kind of ball pen safe in utilization.

Background technology

Pen; be people's routine works; the instrument of indispensability in the study; particularly ball pen, for example oiliness ball pen; aqueous ballpoint pens etc. are because the pen core of ball pen is cheap; be convenient to change; become useful member's first-selection, but the nib of ball pen is made of ball seat body and ball, and is thin and sharp-pointed; easily human body is hindered and cause evil; if touch eyes, then consequence is hardly imaginable, particularly the lower elementary and middle school students of control; when using pen; quarrel and fight noisily through regular meeting, disorderly wave with pen; disorderly wave, easier of the other side's glasses; the accidental injury of health; there is bigger hidden danger, dangerous.

Summary of the invention

The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of pen core can return to ball pen safe in utilization in the penholder under stress.

For achieving the above object, the utility model adopts following technical scheme:

A kind of ball pen safe in utilization, comprise pen core, penholder, on penholder, be provided with fixedly cutting ferrule of pen core, pen core fixedly cutting ferrule is positioned at the position that holds a pen when writing, pen core fixedly cutting ferrule is enclosed within the outside of penholder, pen core fixedly is fixedly connected with at least 2 L shaped elasticity card bases in the cutting ferrule, and the dop of L shaped elasticity card base bottom passes the through hole on the penholder, and dop places the outside of pen core.

Owing to adopted technique scheme, pen core is under the effect of gravity during use, to lower slider, make nib pass penholder, owing to need thumb, forefinger when writing, or thumb, forefinger, middle finger are firmly held penholder jointly, and this position pen core fixedly cutting ferrule is stressed, L shaped elasticity card base is stressed, the termination of L shaped elasticity card base is with the pen core clamping, and fixing, can normally write.When hand leaves fixedly cutting ferrule of pen core, L shaped elasticity card base does not stress, under the effect of elastic force, outwards open, pen core is in free state, can be free movable in penholder, nib is stressed a little will to be retreated, and returns in the penholder, prevents that fully thin and sharp-pointed nib from causing evil to the human body wound.Pen core fixedly cutting ferrule generally all is to be made by elastomeric material, if there is not L shaped elasticity card base, pen core fixedly cutting ferrule is exactly that a pen of holding ball pen that has that uses is at present held, and can prevent to press against hand.

The outside of described pen core is provided with at least 2 snap rings, forms draw-in groove between the snap ring, and the width of draw-in groove is greater than the width of L shaped elasticity card base bottom dop.When pen core when fixedly the L shaped elasticity card base of cutting ferrule is stressed, snap in draw-in groove, the upper-lower position of pen core is fixed, and pen core can not slide up and down when writing, and it is more handy to write.

The described pen core fixedly top of cutting ferrule is provided with fixed cover, and pen core fixedly cutting ferrule is fixedly connected on the outside of penholder by fixed cover.Because pen core fixedly cutting ferrule is fixedly connected on the outside of penholder by fixed cover, pen core play about fixedly cutting ferrule is not understood, raising reliability, long service life.

Be provided with the magnet cap at the top of pen core, the magnet cap is barrel-shaped, and the bottom barrel-shaped at the magnet cap is embedded with magnet, and the barrel-shaped blind hole of magnet cap excessively cooperates with the top of pen core; Top at penholder excessively is combined with the pen cap, and the blind end of the pen cap is embedded with magnet; The pole polarity that magnet is relative in the magnetic pole of magnet and the pen cap in the described magnet cap is identical, becomes mutual repulsion state.Use the principle that the magnet homopolarity repels mutually, heteropole attracts each other in the present embodiment, when magnet cap during to the top of penholder, make between the top of the top of pen core and penholder and produce a repulsive force, pen core is under the effect of repulsive force, move downward, make nib pass penholder, be in the state of writing, but only otherwise clutch fixedly cutting ferrule of pen core, because the repulsive force of magnet is smaller, stretch out the nib of penholder and can retreat when stressed, can not cause bigger injury, reach purpose safe in utilization human body.When not writing, the magnet cap forms the cap for brush to the lower end of penholder, have identical effect with the common cap for brush, but because the magnet cap has magnetic, nib generally is made of iron, nib can be fixed on the inner bottom surface of magnet cap, and pen core is fixed, and is difficult for play up and down.With pen be, pulling magnet cap makes the magnet cap break away from penholder, and pen core is drawn out penholder under the magneticaction of magnet cap, enter user mode, and is convenient and reliable.

The described pen core fixedly interior fixedly connected L shaped elasticity card base of cutting ferrule is uniform 3.3 uniform L shaped elasticity card bases more meet ergonomics, and the mode that promptly adopts thumb, forefinger, middle finger to hold a pen jointly can make 3 L shaped elasticity card bases simultaneously stressed, more reasonable.3 non-uniform L shaped elasticity card bases fully can certainly be adopted, also better effect can be or reached as long as meet ergonomics.

Another embodiment of the utility model is, is fixedly connected with spring leaf in penholder, and spring leaf is positioned at the top of pen core when writing state.Upper end with spring leaf control pen core, make nib pass penholder, be in the state of writing, but only otherwise clutch fixedly cutting ferrule of pen core, because the elasticity rate of spring leaf is less, stretching out the nib of penholder can retreat when stressed, spring leaf produces strain, and pen core can overcome the elastic force of spring leaf, and pen core is return in the penholder, can not cause bigger injury, reach purpose safe in utilization human body.

The beneficial effect of the ball pen that the utility model is safe in utilization is that pen core is under the state of not writing, even without the protection of the cap for brush, pen core also can return in the penholder when being under pressure, solved the problem that nib is hurted sb.'s feelings, can not cause big injury human body, safe in utilization.
