Description

The pen of compasses can be made

Technical field

The utility model relates to a kind of field of stationery, particularly relates to a kind of pen that can make compasses.

Background technology

In routine work and learning life, often need to use compasses and pen, especially in the process of Mathematical, solve a problem with auxiliary owing to often needing drawing.In prior art, compasses and pen are two separate individualities, not portable, and need in use frequently to switch between two individualities, use very inconvenient.

Some compasses pens are there are now, these compasses pens existing, the pen write and the pen of compasses are same one-pen, structure can be simplified although it is so, but also there is obvious defect: the pen of compasses is mostly pencil, and the pen write is mostly ball pen, pen or water-color paintbrush, because pencil word is inherently unintelligible, and easily along with the prolongation of time can become more and more unintelligible.If all adopt pencil, the word write so will certainly be caused unintelligible, and pencil is consumption-type, after pencil is finished, compasses pen is also just ineffective; If all adopt ball pen, pen or water-color paintbrush, be just not easy amendment when picture, and easily occurring playing up on drawing, cause lines excessively thick.

Detailed description of the invention

In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.

Refer to Fig. 1-4, for the first embodiment of the present utility model, in the present embodiment, the pen that can make compasses comprises pen 1, compasses cover 5 and rotating shaft 2, rotating shaft 2 is fixed on the top of pen 1, supporting leg 3 with draw point is all fixedly connected with rotating shaft 2 with the supporting leg 4 of band pen core, and the top of pen 1 is provided with the first screw thread male 121, and compasses cover 5 is provided with the screw thread female with the first screw thread male 121 adaptation; The cross section of pen 1 and compasses cover 5 is circle, the cross section of the supporting leg 4 of the supporting leg 3 with draw point and band pen core is semicircle, the radius of the cross section of the supporting leg 4 of the supporting leg 3 with draw point and band pen core is less than the radius of compasses cover 5, and the length of the supporting leg 3 of band draw point and the supporting leg 4 of band pen core is less than the length of compasses cover 5.

Compared to prior art, the pen that can make compasses that the utility model provides, is connected to compasses on the top of pen 1 by rotating shaft 2, the function of pen when writing, once need picture bowlder, reversion pen 1 just can realize the function of compasses.In addition, the pen that can make compasses that the utility model provides is provided with compasses cover 5, when making pen and using, compasses cover 5 is arranged on the top of pen 1, makes two of compasses supporting legs all be contained in compasses cover 5, effectively avoiding when using as pen, people stabbed by draw point on supporting leg, also the pen core on supporting leg can be avoided to fracture, and the moulding of pen can be made more clean and tidy, use also more convenient.And the cross section of two of compasses supporting legs is designed to semicircle, and it is formation one cylinder that two legs folds, and the compasses of said structure are not easy to rock in compasses cover 5, and the protected effect of compasses cover 5 is more outstanding.

In the present embodiment, pen can adopt pencil also can select pen:

When adopting pencil, pen comprises pencil 11 and point protector 12, rotating shaft 2 is fixed on the top of point protector 12, first screw thread male 121 is positioned at the top of point protector 12, the bottom of point protector 12 is also provided with the second screw thread male 122 identical with the first screw thread male 121 model, and pencil 11 assigns in point protector 12.

Because pencil 11 is running stores, in order to ensure can to continue to use, the utility model devises point protector 12, compasses part is connected with the top of point protector 12, pencil 11 assigns on point protector 12, like this after pencil 11 approach exhaustion, and the pencil 11 that can more renew.And, being also provided with the second screw thread male 122 in the bottom of point protector 12, when using when pen, compasses cap being spun in the first screw thread male 121; When compasses use, compasses cap is spun in the second screw thread male 122, very convenient to use.

When using as compasses, conveniently to the operation of compasses, point protector 12 is provided with the anti-skidding striped 123 of a circle.

When adopting pen, pen is pen, and pen comprises for the protection of the cap for brush of nib and the writing portion for writing, and compasses cap is fixed on the upper end of writing portion, and the cap for brush is fixed on the lower end of writing portion.Compasses cover 5 uses as the upper lever of protection pen ink cartridge, because pen carries the cap for brush of protection nib, when making compasses and using, without the need to compasses cover 5 is protected nib, therefore need not design the second screw thread male 122.

Second embodiment of the present utility model, in the present embodiment, the pen of compasses can be made, comprise pen, the supporting leg 3 of band draw point, the supporting leg 4 of band pen core and rotating shaft 2, rotating shaft 2 is fixed on the top of pen, and the supporting leg 3 of band draw point is all fixedly connected with rotating shaft 2 with the supporting leg 4 of band pen core; Pen is provided with supporting leg 3 first groove of the band draw point after for accommodating and folding, and for supporting leg 4 second groove of the band pen core after accommodating and folding; The cross section of the first groove and the second groove is semicircle, the cross section of the supporting leg 4 of the supporting leg 3 with draw point and band pen core is also semicircle, and the radius of the cross section of the supporting leg 4 of the supporting leg 3 of band draw point and band pen core equals the radius of the cross section of the first groove and the second groove.

Compared to the first embodiment, compasses cap is not designed in the present embodiment, 20 devise two grooves, when using as pen, can being contained under two supporting legs in two grooves after folding, preventing when using as pen, people stabbed by draw point on supporting leg, also the pen core on supporting leg can be avoided to fracture, and the moulding of pen can be made more clean and tidy, use also more convenient.

In the present embodiment, pen is pen, and pen comprises the upper cap for brush for the protection of ink cartridge, the lower cap for brush for the protection of nib and the writing portion for writing, and the upper cap for brush is fixed on the upper end of writing portion, and the lower cap for brush is fixed on the lower end of writing portion; Rotating shaft 2 is fixed on the top of the cap for brush, and the first groove and the second groove are all positioned on the cap for brush.Certainly, this is only a specific embodiments of the present utility model, and the type of pen of the present utility model is not limited in this, also can be pencil, water-color paintbrush, mechanical pencil etc.

Be only several specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
