Abstract

The utility model discloses a double-tip pen, which consists of two pen bodies through a connecting part. The connecting part comprises a pen connecting end, a connecting rod and a bearing, wherein the pen connecting end and the connecting rod are connected to form a rotatable structure through the bearing, one end of the pen connecting end is a rotation stopping end which is of a cubic structure, the tail ends of the two pen bodies are connected together through the connecting part, so that the two pen bodies are not distinguished to be a main pen and an auxiliary pen, the limitation on rotatable adjustment is less, and due to the existence of the rotation stopping end, when the pen bodies rotate to 180 degrees, the pen bodies can be clamped by the rotation stopping end. The double-tip pen has the beneficial effects that when only one pen is needed for use, the other pen body rotates to the rotation stopping end to be clamped, and can not continuously rotate.

Description

Two-headed pen

Technical field

The utility model relates to a kind of two-headed pen, relates in particular to a kind of Multifunctional writing appliance.

Background technology

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

The utility model content

The purpose of this utility model provides a kind of two-headed pen, and the degree that can regulate rotation is larger, and can the restricting rotation degree can turn to the one-pen use.

According to an aspect of the present utility model, 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 rotary 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 like this a major-minor structure, make its rotation regulate use more convenient, 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, as long as being forwarded to 180 °, another handwriting blocked by the spline end, just automatic rotating more not.

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, so 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 the utility model one embodiment;

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

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 has schematically shown the two-headed pen according to a kind of embodiment of the present utility model.

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 less.

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 rotary structure with connecting rod 22 by bearing 23, simultaneously a side of a link 21 is the spline end 24 of cube structure, although 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, consisted of 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 rotary 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.
