Abstract

The invention discloses a double-head pen. The double-head pen comprises two pen bodies and a connecting part, wherein the connecting part comprises a pen connecting end, a connecting rod and a bearing; the pen connecting end is connected with the connecting rod through a bearing to form a rotary structure, one side of the pen connecting end is a rotating stopping end in a cubic structure; and the tail ends of the two pen bodies are connected together through the connecting part, so that the two pen bodies are not distinguished as main and auxiliary pens, have smaller rotatable adjustment limitation and can be blocked by the rotation stopping end when rotating to 180 degrees. Consequently, the pen has the advantages that when only one pen needs to be used, the other pen body is rotated to be blocked by the rotating stopping end and cannot rotate any more.

Description

Two-headed pen

Technical field

The present invention relates to a kind of two-headed pen, relate in particular to a kind of multifunctional double-headed pen.

Background technology

Existing two-headed pen generally all is a major-minor structure, because secondary pen is general shorter and smaller, when drawing bigger circle or wideer parallel lines, need rotate bigger angle, and the scope of final restriction is many, this structure is when only need using nib of one-pen in addition, also to or dismantle secondary pen rotation, cumbersome.

Summary of the invention

The purpose of this invention is to provide a kind of two-headed pen, the degree that can regulate rotation is bigger, and can limit the rotation degree and can turn to one-pen and use.

According to an aspect of the present invention, a kind of two-headed pen is provided, has been made of by attaching parts two handwritings, attaching parts comprise a link, connecting rod and bearing, link and connecting rod connect into rotatable structure by bearing, and a side of a link is the spline end of cube structure.

Its beneficial effect is, two handwritings connect by terminal, there is not a major-minor structure like this, it is more convenient to make its rotation regulate use, side in attaching parts is designed to a spline end in addition, and the rotation of limit pen is in 180 °, like this in the time will using single, blocked by the spline end as long as another handwriting is forwarded to 180 °, just can not rotate automatically again.

In some embodiments, one of them handwriting in two handwritings, its writing part is the nib of bipitch structure.

Its beneficial effect is, like this when using single handwriting, when especially drawing simple two ways, as long as be the just passable of Double-nib with one of them, makes that the use of two-headed pen is wider, has more convenience.

Description of drawings

Fig. 1 is the overall schematic of the two-headed pen of an embodiment of the present invention;

Fig. 2 is the structural representation of the connecting portion of Fig. 1;

Fig. 3 is the structural representation of the nib of Fig. 1.

The specific embodiment

The present invention is further detailed explanation below in conjunction with accompanying drawing.

Fig. 1 has schematically shown the two-headed pen according to one embodiment of the present invention.

As shown in Figure 1, two-headed pen comprises that the end of 1, two handwriting 1 of two handwritings links together by attaching parts 2, and just there is not the difference of major-minor pen in such two handwritings, rotatable adjusting restricted littler.

In conjunction with Fig. 2, attaching parts 2 comprise a link 21, connecting rod 22 and bearing 23, link 21 is exactly the end of handwriting 1, link 21 connects into rotatable structure with connecting rod 22 by bearing 23, simultaneously a side of a link 21 is the spline end 24 of cube structure, though the degree of such two handwriting 1 rotatable adjustings improved, owing to the existence of spline end 24, when handwriting 1 rotates to 180 °, will be blocked by spline end 24.Such benefit is, when only needing use one-pen, another handwriting 1 forwarded to by spline end 24 block, and just can not be rotated further again.

In conjunction with Fig. 3, in two handwritings 1, can be the writing part of one of them handwriting 1 nib 3 of bipitch structure, so in use, just many again functions are available, two parallel bipitch structures, neither can have influence on the picture circle, can also be as the effect of drawing simple parallel lines.

Claims

1. two-headed pen, it is characterized in that, constituted by attaching parts (2) by two handwritings (1), described attaching parts (2) comprise a link (21), connecting rod (22) and bearing (23), described link (21) connects into rotatable structure with connecting rod (22) by described bearing (23), and a side of described link (21) is the spline end (24) of cube structure.

2. two-headed pen according to claim 1 is characterized in that, one of them handwriting (1) in described two handwritings (1), and its writing part is the nib (3) of bipitch structure.
