The specific embodiment

Embodiment 1: the rubber that cooperates hole 2 is set.

On rubber body 1, make a call to a hole littler, the rubber hole is enclosed within the pencil tail end than pencil external diameter.Utilize rubber elasticity, rubber is fixed on the pencil tail end.Do not fall down, do not burst rubber not only but also can repeat repeatedly conveniently to take off, set up firmly and be as the criterion with rubber.

Cooperate the hole to be of a size of: internal diameter is than the little 0.1～0.5mm of pencil external diameter, dark 8～15mm (pencil with used diameter 8mm is the example explanation).

Because new wooden pencil is longer, as the rubber of setting up is oversize, Writer's hand will soon be stranded, and feels under the weather, and influences the enthusiasm that people use this rubber.Comfortable for guaranteeing to write, adapt to common people's custom, rubber is little, its quality with 3～6 grams for well.

Cooperate the hole to beat on the smallest cross-sectional of rubber, can maximally utilise rubber, the profile minimum dimension of rubber is than more than the big 2mm of pencil external diameter, its minimax size than less than 3 for good.

Method with rubber has (this moment, rubber case was at a tail):

1), can not take off rubber and arrest pencil use rubber.

2), do not take off rubber, arrest rubber with hand and use.

3), take off rubber and use after, be positioned on pen again and go up and continue with pen.

Above-mentioned three kinds of usings method, best with method 2.The number of times that method 1 is used is less, and rubber is junk easily, loses function fixing on pen.Method 3 is used trouble.And method 2 can allow rubber few stressed, and then less breakage, can guarantee the fixed function of rubber at a tail in more times ground, and use is simpler again, thereby has avoided the shortcoming of the two.

When rubber can not well be fixed on the pen, just take off and renew in addition, old still can use.

From the above, because rubber is fixed on the pencil afterbody always, when writing with a pencil, when using rubber, can use rubber easily, as long as pencil is not lost, rubber just can not lost.This just greatly reduces the chance of losing rubber.And this rubber is replaceable, and is convenient when changing, and pressed as long as the pencil afterbody is aimed at rubber hole one.Therefore this rubber has anti-function of losing, and has also avoided pencil later stage of aforesaid band rubber can not use the shortcoming of rubber, has also removed the fixedly material of rubber less.Be whenever this rubber can both follow pencil.

The utility model can be positioned on any wooden pencil tail end, as long as the rubber hole changes and the suitable degree of depth along with the size shape of pencil breech face.And the size shape color of rubber also can change, and can derive various rubbers that can adapt to different consumer tastes.Thisly also can adapt to utilization to propelling pencil.

In addition: for increasing the durability of this rubber, promptly guarantee its access times as much as possible, can adopt the reinforcement sleeve that adds metal or plastics or paper in the outside in rubber hole.To increase its intensity, prolong its access times.Or the intensity that makes the rubber of periphery, hole with the particular processing method is strengthened or adopt the big rubber of intensity to do.

As Fig. 1, on the end face of the cylindrical rubber of a Φ 10 * 20mm, make a call to the cooperation hole of Φ a 7.5 * 11mm.It is positioned on the tail that now commercially available diameter is the pencil of 8mm, and rubber just has been fixed on the pencil like this.Time spent just can not taken off rubber and use an erasing rubber delead person's handwriting on paper.Also can take off erasing rubber goes to be positioned on a tail again behind the person's handwriting.Rubber does not take off from pen when writing certainly.Can not the time spent when this rubber, take off pacify again one new.

Do the trouble that time spent of causing when having avoided this little rubber singly to put on the table can not find or loses like this, also avoided the worries that to change with the fixing rubber of rolled tin now.

Embodiment 2: the rubber that mating groove 3 is set

In the one side of rubber, to do a square opening and keep to the side, the cross section is 3/4ths circles approximately, runs through the groove of rubber.Can be with pencil shaft repeatedly easily from the opening turnover, pencil shaft is after groove is pressed into, and rubber can not endwisely slip along pencil, can not allow penholder skid off from opening oneself, guarantees that simultaneously rubber is not bursting at the collision, and also can guarantee to repeat repeatedly to use.Opening is wide than the little 1-3mm of pencil external diameter, dark 2-3mm, and the groove internal diameter is than the little 0.1-0.5mm of pencil external diameter.

This kind rubber can be fixed by any part on pencil shaft, still can comfortablely write for guaranteeing the pencil of having fixed this kind rubber.Can there be two positions available.

Position one a: afterbody.Be about to rubber be fixed on the people when holding a pen penholder expose on that section penholder of the back of the hand.Comfortable when writing, rubber does not write to good not influence again near the back of the hand as far as possible.

Position two: pen middle part.When holding, by thumb, forefinger forms in that section of pencil in the circle.Rubber this moment (people hold a pen when writing palm of the hand space-time) and be fixed on the penholder in the palm of the hand.This kind fixing means, applicable bigger rubber, by practice as can be known, analyze its reason: hold pen when writing, pen is having two fulcrums on hand, on the hand tiger, is booster action in the time of one, and the acting in conjunction that thumb forefinger middle finger three refers in the time of is main effect.When certain point adds same rubber more than the back of the hand again at the tail end of pen with near the middle part of pen, be fulcrum with the tiger so, the power effect that the thumb forefinger is subjected to will be different.By lever principle as can be known, be placed on the rubber of pen end, can be greatly to the active force of thumb forefinger.Under same holding capacity, the rubber that is fixed on penholder middle part or close middle part can be greatly.

When common people use rubber, hold in the hand and begin to write, thumb forefinger middle finger three refers to holding the erasing rubber wrongly written character.In view of relatively being accustomed to, when rubber was fixed on pen end, the time spent needed only the nib tuning palm end, the rubber tuning tiger of a tail, and three make a comment or criticism arrests usefulness.With after, recall to again.At this moment rubber still is fixed on a tail, and is easy to use.Certainly, also can directly take off rubber in the penholder side, with after still be clipped on the penholder.

When rubber is fixed on when middle part pen, when writing, rubber is in the palm of the hand, and the time spent is as long as access rubber, with after recall to the palm of the hand again and get final product.Also can take off rubber, with after be positioned on the pencil, can apply in a flexible way optional penholder middle part, afterbody as for the position of peace.Time spent not only can take off but also can not take off.

The employed most of rubber of the applicable present people of this rubber, changeable, shape is not limit.As long as can open a groove of putting into pencil shaft on the rubber, just can with the rubber clamping on pencil shaft, also needn't take off when writing with a pen word, and remove to use rubber at any time.Avoided rubber to be placed on separately on the desktop, because of various touchings go from place to place, and the worry that people can not find the time spent.Also reduced the chance that rubber is lost.Because pen to lose chance littler than rubber.Propelling pencil also is fit to use.

As shown in Figure 2, on the square rubber minor face of 30 * 20 commonly used * 7mm, open the round bottom of a Φ 7.5mm, opening be suitable for reading for the 4mm end opening be the wide groove of 5mm.Just having made of such trough of belt with a rubber.The existing commercially available thick pencil shaft of Φ 8mm commonly used is inserted in the groove of this rubber, just can makes rubber be fixed on any part on the pencil shaft.When writing with pencil, rubber can be fixed on the back of the hand, also can be fixed in the palm of the hand.During with the erasing rubber word, can make rubber not from pen with also can take off rubber with after set up again.When writing with a pen word in a word, pencil and rubber can be not separated.The worries that the time spent can not find when rubber had just avoided independent like this.

This rubber also can be used on the existing propelling pencil, and usage is the same.

Embodiment 3: the rubber that mating holes 4 is set

Make a call to a through hole than the little 0.1-0.5mm of pencil external diameter in the place that rubber keeps to the side, back gauge Cushions minimum should be stayed the above distance of 1mm outside the hole.Pencil shaft is inserted in the hole, and rubber just can be fixed at any position on penholder.

This kind rubber usage can not be taken out rubber when only using and set up with that groove rubber usage is arranged is the same from the side of penholder.This kind rubber also can be used on the propelling pencil.

Such as Fig. 3 reality, make a call to the hole of a Φ 7.5mm on commonly used 30 * 20 * 7 the square rubber by the place of minor face, a Here it is rubber that has a hole, in the pencil holder cover hand-hole that Φ 8mm is thick, rubber can be fixed on the pencil holder any part.When writing with this pen, rubber can be fixed in the back of the hand also can be fixed in the palm of the hand.When wiping word, can take off also and can not take off with it.Convenient if any groove not only with rubber.But a fixing effect trough of belt is good with a rubber.

Rubber just is difficult for losing with pen during owing to write.

On arbitrary propelling pencil that this rubber also can be used for using always, its usage is the same.
