Pen, it is convenient and practical.Compasses volume after folding is minimum, modern design, is furnished with key chain, carries more convenient.In the axis side of the pen cap
Upwards without any blocking, convenient for adjusting the length of pen, to coordinate the length of compass leg.
In order to achieve the above objectives, the utility model uses following technical solution, a kind of drawing compass, including mutually cuts with scissors
The compass leg and the pen cap connect, on the pen cap setting be used for holding out against marking closely for pen, the pen cap is the tubular body of formula up and down,
Without view obstruction on the axis direction of the pen cap, an otic placode is arranged in the pen cap outer wall, and the compass leg includes principal arm, draws
Point, the principal arm upper end and otic placode are hinged, and principal arm lower end and stroke point are hinged, and described stroke of sharp length is less than or equal to the length of principal arm
Degree.
In order to achieve the above objectives, the utility model uses following technical solution, a kind of drawing compass, including mutually cuts with scissors
The compass leg and the pen cap connect, on the pen cap setting be used for holding out against marking closely for pen, which is characterized in that the pen cap is up and down
An otic placode, the compass leg packet is arranged without view obstruction, the pen cap outer wall on the axis direction of the pen cap in the tubular body of formula
It includes and draws Retractive leg sharp and that at least three-level is nested successively, described stroke of point is telescopic in the Retractive leg of most next stage, most
The Retractive leg upper end of upper level and otic placode are hinged, setting group handle on described stroke of point.
The cannelure for accommodating and dialling handle is opened up on the Retractive leg.
The hinged place of the Retractive leg and otic placode, which is worn, is connected to chain belt.
Compared to the prior art, the utility model has the advantages that：
1, compasses are designed as single-leg type, and cost of manufacture is lower；
2, the pen cap is cartridge type, and can be loaded the various pens such as pencil, water-color paintbrush, convenient and practical；
3, compasses volume after folding is minimum, modern design, is furnished with key chain, carries more convenient；
4, without any blocking on the axis direction of the pen cap, convenient for adjusting the length of pen, to coordinate the length of compass leg；
5, compasses design is safe and reliable, is particularly suitable for students in middle and primary schools and uses.
