Background technology

We just began to be coated with pencil drawing about two years old, and at primary school two, three grades now, though used propelling pencil and pen, but still the bound pencil of using.

A pencil is about 180mm, and the actual part of using is also with regard to about half, to continue certainly with going down be not cannot, but feel a bit not handy, otherwise will hold, even like this, still having one big section can not use.

Original child with the pen drawing, write and just like holding from the near place of some of nib, though Papa and Mama often remind: " hand will a little further be held to such an extent that descended very much from nib! " " what the eyes that write like this can be near-sighted, the neck president is askew." " one-inch one fist one chi has been forgotten? " one-inch is meant that finger is from the nib one-inch; one fist is a chest will have the distance of a fist from desk, and a chi is that eyes are far away from desktop one chi, so just can not take off on desk by slanting head; accomplish to come back and square one's shoulders, protect eyes and favourable body development.Therefore will inevitably hold too down with short pencil, directly influence writing posture, affect one's power of vision and body development.Keep in our drawer now greatly with the pencil of having lacked, and thrown away countless, national so much child will use pencil, what does the pencil of throwing away have? this is great waste!

How long is one-inch? though Papa and Mama usually give directions to us, gesticulate, we have forgotten soon, because we are also too little when beginning with pencil, length are not had notion, have grown up some exactly, can not all take the ruler amount of going at every turn.And write once taking up one's pen, naturally and understandably just held, we still are good, and finger is also on the circular cone of cutting out, and the child who has has held on the nib, is that visible for not askew head? therefore many children are from the little method of holding a pen of just not grasping, the writing posture of not forming, in addition have influence on reading also low head, turning round neck and bending waist, in case formed custom, it is just so easy to change.We just eight, nine years old, classmate of the same class just has several to put on glasses, causes myopia that many-sided reason is arranged certainly, but writing posture is to being not a very important factor.

We think in this way, if as long as we have can a let us write with a pen word, drawing of sign just know and will be held in what position how nice this is that perhaps myopia can reduce a lot like that from little pencil with regard to usefulness.If what pencil shaft also more slightly, was held is local softer just better, writing word will be more easily, and the finger wrist is not easy to tire out.Therefore we want to add a cover to pencil, under grandmother (grandmother's) help, have invented the point protector of introducing below finally.

Summary of the invention

In order to increase effective use length of pencil, cut the waste, economize on resources, guide children correctly to hold a pen simultaneously, form good writing posture, healthy growth, the utility model provides a kind of reusable point protector, consumptive pencil packed into use in the point protector, just can prolong effective use length, children begin just can hold correct position with pencil from the child period.

The technical scheme that its technical problem that solves the utility model adopts is: add cover on pencil shaft, be made up of the interior cover of strap clamp pawl and the overcoat of tight device with lock, clamp with spiral power or spring force.

The position making that correctly holds a pen when writing on the coat obviously indicates, as coil, figure, color, literal, spacing ring.

The beneficial effects of the utility model are: effective use length of pencil is increased, and remaining just very short pencil stub that can not press from both sides has reduced waste, has saved resource; Obvious sign is arranged, guide children to begin period to take pen just to know to be held in what position from the child, that forms is accustomed to pen, helps vision protection; The spot size that holds a pen is suitably strengthened, and join soft cover, make to write to become more comfortable; Reusable, can make pencil reach the ideal dimensions that use needs, therefore can correspondingly reduce existing pencil shaft, be equipped with the utility model, thereby further save material, reduce cost, reduce resource consumption.

The specific embodiment

1. according to the technical solution of the utility model design and produce launch products, satisfy consumer wants.

In first embodiment shown in the accompanying drawing 1, interior cover (1) front end is shaped on three elasticity jaws, overcoat (2) front end has the locking conical surface, tail end has one section screw thread to cooperate with interior cover (1), overcoat (2) internally overlaps the elasticity jaw that interior cover (1) front end could be locked or unclamp to (1) rotation mutually, is contained in the interior pencil C of interior cover (1) to D thereby clamp or unclamp.A is a spacing ring, and the B place, position that holds a pen above it makes and points the figure that holds a pen.The characteristics of this embodiment are not have finding, are fit to the child and use.

In second embodiment shown in the accompanying drawing 2, elasticity jaw (3) is divided into two parts with interior cover (1) to be made, with being threaded, lock sleeve (4) and overcoat (2) are with interference fit or gummed, be the parts that to roll over, elasticity jaw (3) is made with lock sleeve (4) available metal material like this, improves service life, increases reliability.Spring (5) makes lock sleeve (4) press to spring jaw (3) to be in locking state, and soft cover (6) makes and holds a pen comfortablely, and the spacing ring A of its front end can also can make part separately for one with soft cover (6).

Because present pencil external diameter has plurality of specifications (containing circle and hexagon), the utility model is made the supporting with it use of corresponding specification.The external diameter of overcoat (2) relatively is fit to children in 9～13mm scope uses, so a large sum of rod pencil (greater than 9mm) in the market is not suitable for joining the utility model again.

2, advise to the parties concerned.

(1) the relevant medical research of suggestion mechanism is investigated children's mode of holding a pen, wholesome height and the penholder size of holding a pen proposed, propagate and educate effectively, and together with relevant department to the children below three grades of primary school with the pen, comprise that requirements such as propelling pencil, ball pen, gel ink pen, pen, writing brush make obviously and indicate at its penholder position that correctly holds a pen, the guiding children correctly hold a pen, with form good drawing, the posture of writing.

(2) pencil is disposable consumptive; after the supporting use of the utility model is arranged; pencil itself just need not to consider to hold a pen the feel problem; penholder mainly plays the effect of protection pen core; therefore suggestion revision relevant criterion suitably reduces the pencil shaft external diameter, and normalization; to save material, reduce resource consumption.Propelling pencil is directly to add cover on pen core, has saved pencil shaft, but it is not suitable for particularly preschool child's use of primary grades student, therefore can't replace existing pencil fully.

(3) by the waste of pencil, associate the ball pen of present usefulness, gel ink pen, signature pen, though just pen core is disposable, penholder is can be reusable, but in fact all become disposable, it at first is the pen core that is difficult to be fitted on corresponding specification on the market, mostly can not buy pen core specially with the person besides, return, use up the pen core penholder and lost together but buy several or a box pen, change Zhi Xin (this also is that producer and dealer like), therefore advise that country makes pertinent regulations, pen and pen core bundle sale are according to penholder decoration in service life core, join 5-10 pen core such as one-pen, rather than buy pen and pen core separately, though be slight penholder, consumption is big, total amount is just big, and its raw material is the energy resources that lack from China.
