Description

The writing pen tool

The utility model relates to a kind of writing pen tool, belongs to the stationery field.

Society goes up industrial and commercial busy now, stationery mostly is office and the used necessity of daily writing, and the structure of known pens tool, see also Fig. 1, mostly be to adopt penholder 100 root edge systems with 101 in the annular groove portion of micro-pits, and outside annular groove portion, be nested with one by the tubular pen cap 200 of soft elastic material, sheathed in regular turn again pencil lead 300 and sealed written 400, its finger tip clamping is in pen cap place when allowing the user grip penholder, it is because of possessing soft flexible pen cap skin, but reaches effects such as making finger tip comfortable grip and on-slip.

Yet, generally when a gripping tool is write, mainly be with thumb, forefinger and middle fingertip support penholder 100 leading portion portions, and by between thumb and forefinger by holding portion's holding penholder back segment, and because of the soft elasticity pen cap 200 be with fixing mode, be placed on the groove place of micro-pits, produce unavoidably with finger tip between relative slip, the phenomenon that severe patient will have pen cap pull-up to fall, then easily cause gripping and rock and influence the steadiness that grips penholder, and in a plastic cement and a metal system tool, all adopt this to be nested with modes such as a tool layer, obviously do not have the people this to be had any part of improving, the utility model be the applicant be conceived to this at first development and Design product to the solution of above-mentioned defective is proposed.

The purpose of this utility model provides a kind of steadiness that increases when holding a pen, even and write a tool that also is difficult for feeling fatigue for a long time.

For reaching above-mentioned purpose, a kind of writing pen tool of the utility model, it is characterized in that on the penholder that locking one unifies three layers of fabricated structure body of the soft elasticity pen cap by inside and outside metallic sleeve pipe therebetween, wherein be provided with the circular hole of a plurality of arrangements in the outer tube tube wall, the upper and lower both sides of inner layer sleeve are provided with thread, screw togather penholder and nib respectively, and the circular hole of arranging on the corresponding outer layer sleeve of the pen cap of clamping between inside and outside layer sleeve pipe is provided with a plurality of protruding grains, protruding grain protrudes out the circular hole of outer layer sleeve.

The pen cap is made for the silica gel material.

In sum, the writing pen tool that the utility model disclosed, also and between penholder be mutually locked by adopting three layers of knockdown metal sleeve and silica gel to grip pen cap combination, effectively increase the contact effect of grip part and make to write and have firm sense, and write for a long time and the difficult tired out sense that produces, obviously promote effect, had more progressive and practicality.

Below,, after conjunction with figs. is described in more detail in, make increase to understanding of the present utility model with a preferable feasible embodiment now with regard to structure function of the present utility model.

Fig. 1: be the sign an undertaking combination dissected figure of structure of known pens.

Fig. 2: be three-dimensional system diagram of the present utility model.

Fig. 3: the three-dimensional system diagram that is the utility model pen cap structure.

Fig. 4: the three-dimensional combination figure that is the utility model pen cap structure.

Fig. 5: be combination dissected figure of the present utility model.

Fig. 6: be embodiment schematic diagram of the present utility model.

See also Fig. 2, shown in Figure 5, be the utility model writing pen the sign an undertaking three-dimensional system diagram and the combination dissected figure of structure, its primary structure is to be a metal system tool, 10 root edge endoporus places are provided with internal screw thread 11 in penholder, other is provided with a metal system inner layer sleeve 20, these inner layer sleeve 20 calibers are slightly less than the external diameter of penholder 10, and on inner layer sleeve, following place all is provided with external screw teeth 21, whereby and screw togather locking with the internal screw thread 11 of penholder 10 root edges, lock mutually by inner layer sleeve 10 and epimere penholder 10, and the groove of formation micro-pits, unify the soft elasticity pen cap of making by silica gel 40 in this groove place cover, this soft elasticity pen cap surface is the relief grain 41 that is provided with equidistant arrangement, and outside the pen cap, be nested with an outer layer sleeve 30 again, this outer sleeve pipe tube wall is to be same as the circular hole 31 that protruding grain position, pen cap surface is provided with some arrangements, and make pen cap clamping in inner layer sleeve 20, outer layer sleeve 30 is middle (as Fig. 3, shown in Figure 4), pencil lead 60 is placed in the penholder and in inner layer sleeve 20 bottom external screw teeths 21 places locking one nib 50 and gets final product;

This uses the grip part by writing of making of the metal sleeve 20,30 of three-layer type combination and the silica gel system pen cap 40, not only can increase the firm sense of grip part, and allow the pen cap closely be sleeved in the inside and outside layer sleeve pipe, the sleeve pipe group can be locked on the penholder 10, and effectively prevent the puzzlement point of known pens jacket layer landing in penholder, and writing for a long time and the difficult tired out sense that produces, really is the design of a practicality, innovation.

The above only is of the present utility model one preferable enforcement example, can not with the scope implemented of qualification the utility model, all equalizations of doing according to technical solutions of the utility model change or modify, and must belong in the scope that technical solutions of the utility model contain.
