Abstract

An automatic double protection pen which can protect the pen tip and the eyesight is provided. The utility model is assembled by installing a sliding block, a pen core, a spring and a pen head into a pen holder and embedding a button into a pen holder notch. The main difference from the present common automatic pen is that a controlling device of the pen core is designed into a pressing button at the pen holding position, and no obvious unevenness exists on the surface of the pen holder, the comfort of the pen holding is not influenced, and the normal writing habit needs not to be changed. When the pen is hold to write, the force pressing the button by a finger enables the sliding block contacted with the pressing button to be pressed to drive the pen core to extend out of the pen holder. The pen core can not retract automatically back to the pen holder when being not used to write. The pressing button controlling the telescopic motion of the pen tip is designed at the pen holding position, and the utility model has the function of eyesight protection. Besides a ball pen, the device with the structure can be developed into a plurality of various automatic pens.

Description

Automatically two pens that protect

Affiliated technical field

The utility model relates to a kind ofly can protect starting writing certainly of nib, vision protection.

Background technology:

At present, the steel ball at ball pen tip is more and more littler, the word that writes out, and lines are more very thin, attractive in appearance.But little steel ball easy coming off more just in nib and its thing collision process becomes a difficult problem of a system industry.Known ball-point pen structure mainly contains two kinds.A kind of self-locking device that has, nib can or be locked in the position that can write or is locked in shaft of a writing brush inside after the end user operates, because locking device is arranged, so whether above-mentioned nib state and operator's hand breaks away from pen all has nothing to do.Another kind has the cap for brush, and nib exposes outside the shaft of a writing brush all the time.These two kinds of pens are under the situation of not noting protecting, and nib just might suffer damage when colliding with its thing.

Present these all neither one can limit the position that accurately holds a pen.This is totally unfavorable for the child who just learns to write with the people who needs the correction pen holding posture.The bad custom that holds a pen also is the major reason that student eyesight descends.

Summary of the invention:

The purpose of this utility model provides a kind of pen core anticollision and limits two automatically pens that protect of pen griping position.

The technical scheme that its technical problem that solves the utility model adopts is: handwriting by nib, the shaft of a writing brush, press button, slide block, spring, pen core, also can add in pipe form.On the shaft of a writing brush at nib one-inch place, longitudinally opening a little rectangle notch, respectively there is a little cylindrical pit two inboards by notch one end, this pit to notch is bumped into from the outside to press two cylindrical protrusions on the button, make to press to be fixed on the shaft of a writing brush and not come off, also make an end of pressing button can be in this notch do by a small margin rotation around the line of two pits by bond energy.Pressing in the shaft of a writing brush is equipped with one below the button and can moved and can pass the slide block of pen core in its longitudinal center along the shaft of a writing brush, this slide block is the rectangular triangular shape in side of two symmetries longitudinally, the inclined-plane at its hypotenuse place with press button and contact, the inclined-plane is in stressed pressing under the button extruding, make slide block overcome the elastic force of front springs, the drive pen core moves forward, and nib exposes the shaft of a writing brush.Press the grip of the suffered power of button when writing for the writer holds a pen, so after grip was cancelled, under the effect that is subjected to spring force, whole pen core moved to penholder pipe tail end, nib is return the shaft of a writing brush.The position at place and Writer's grip application point normally holds a pen when writing just.

The beneficial effects of the utility model are: only when holding the correct position of penholder, nib just stretches out the shaft of a writing brush, and pen is when dropping to the ground because of carelessness, because hand has left penholder, nib is return the shaft of a writing brush immediately, so nib can not be damaged; On the other hand, if Writer's hand can not be held in correct position, nib can not expose yet, and has reached the purpose of the vision protection that correctly holds a pen.
