The utility model is characterized in that an inner thread of the pencil body is connected to the outer surface thread of the sleeve, the upper end of the pencil is embedded in the inner part of the lower end of the sleeve, the upper end of the sleeve is connected to the lower end of the handle, and the inner part of the anti-sliding membrane is sleeved on the outer surface of the pencil body.

Description

The Convenient pencil cover

(1) technical field:

The utility model relates to the Convenient pencil cover, divides the clamper that belongs to pencil or chalk by International Patent Classification (IPC) (IPC); The pencil connector; The technical field of the protector group of reservoir tip.

(2) background technology:

At present, the clamper that has now and once had about pencil or chalk; The pencil connector; The technology of the protector group of reservoir tip need all be done very fruitful effort to making things convenient for point protector, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Yang Linfa, Granted publication number is CN2222068Y, China Patent No. (ZL) is: No. 95243728.7 utility model title is the utility model patent of " Holder for pencil sharpening ", and the technical scheme that is adopted is at the clamper of pencil or chalk; The pencil connector; The protector group technical elements of reservoir tip is a routine of great value invention, and it has solved the technical problem of Holder for pencil sharpening protection hand effectively.But still have some deficits, it also is difficult to solve increases a length, anti-skidding technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of Convenient pencil cover.Increase a length, anti-skidding technical problem to solve.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: Convenient pencil cover of the present utility model mainly is made of handle, handwriting, non-skid film, pullover, pencil.

In shape, structure and combination thereof, Convenient pencil cover of the present utility model with the essential features that immediate prior art has is: the integral body of pencil is nested in the inside of point protector, be combined into the combining structure of point protector shape, function has been the effect of point protector.In shape, structure and combination thereof, the Convenient pencil cover of the present utility model technical characterictic different with immediate prior art is: the internal whorl of handwriting is connected pullover outer surface thread place, the upper end of pencil is nested in pullover inside, lower end, pullover upper end is fixedly connected on the lower end of handle, be combined into the combining structure of expansion link shape, function be with different pens embed pullover in increasing its length, and length-adjustable effect.The internal sleeve of non-skid film is combined into the combining structure of cylindrical shape at the outer surface of handwriting, and function has been anti-skidding effect.So just reached Convenient pencil cover of the present utility model for realizing increasing a length, anti-skidding purpose.

The beneficial effect of the Convenient pencil cover of utility model is that the utility model is to solve to increase a length, anti-skidding technical scheme that technical problem adopted and the clamper about pencil or chalk existing and that once had; The pencil connector; The technology of the protector group of reservoir tip has been compared two place's advantage and improvement:

First, be connected pullover outer surface thread place owing to designed the internal whorl of handwriting in the technical scheme of Convenient pencil cover of the present utility model, the upper end of pencil is nested in pullover inside, lower end, pullover upper end is fixedly connected on the lower end of handle, be combined into the combining structure of expansion link shape, so easier solution with different pens embed pullover in increasing its length, and length-adjustable technical problem.

The second, owing to designed the outer surface of the internal sleeve of non-skid film in the technical scheme of Convenient pencil of the present utility model cover, be combined into the combining structure of cylindrical shape, so the anti-skidding technical problem of easier solution in handwriting.

(4) description of drawings:

Accompanying drawing provides the structural representation of Convenient pencil cover of the present utility model:

Fig. 1: the overall structure schematic diagram that is Convenient pencil cover of the present utility model;

The label declaration at each position in the schematic diagram:

1 handle, 2 handwritings, 3 non-skid films, 4 pullover 5 pencils

(5) specific embodiment:

Below in conjunction with accompanying drawing, Convenient pencil cover of the present utility model is increased a length for realizing solving, the optimal way of the technical scheme that anti-skidding technical problem is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, Convenient pencil cover of the present utility model mainly is made of handle 1, handwriting 2, non-skid film 3, pullover 4, pencil 5.Its major part non-skid film 3, pencil 5 are selected for use by market.Its handle 1 is a cylindrical shape, is material with plastics, through the machining manufacturing.Its handwriting 2 is cylindrical shapes, is material with plastics, through the machining manufacturing.Its pullover 4 is cylindrical shapes, is material with plastics, through the machining manufacturing.

In shape, structure and combination thereof, Convenient pencil cover of the present utility model with the essential features that immediate prior art has is: the integral body of pencil 5 is nested in the inside of point protector, be combined into the combining structure of point protector shape, function has been the effect of point protector.In shape, structure and combination thereof, the Convenient pencil cover of the present utility model technical characterictic different with immediate prior art is: the internal whorl of handwriting 2 is connected pullover 4 outer surface thread place, the upper end of pencil 5 is nested in pullover 4 inside, lower end, pullover 4 upper end is fixedly connected on the lower end of handle 1, be combined into the combining structure of expansion link shape, function be with different pens embed pullover in increasing its length, and length-adjustable effect.The internal sleeve of non-skid film 3 is combined into the combining structure of cylindrical shape at the outer surface of handwriting 2, and function has been anti-skidding effect.

Below by using method, further set forth Convenient pencil cover dynamic structure relation of the present utility model: in use, when needs increase length, according to theory of mechanics, at first the Antu shows and assembles each element, then pencil 5 is nested in pullover 4 inside, and different pens can be installed as required, swing handle 1 drives pullover 4 rotations and regulates length then again, thereby finishes the task of pen being increased different length.So just realized that Convenient pencil cover of the present utility model increases a length, the technical scheme of anti-skidding technical problem for reaching.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of a system factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of Convenient pencil cover of the present utility model better with the demand of supply educational circles.
