Description

Multipurpose compasses

The utility model relates to a kind of compasses.

Present known compasses, but form by a compasses head and two compass foots that are positioned at the jag of below, wherein an iron pin is equipped with at the top of a pin, and a stamen is equipped with at the top of another pin, and the iron pin is used for the fixing of the center of circle, and a stamen is used for drawing.The shortcoming of this compasses just is: function singleness can only be used for picture circle.

The purpose of this utility model provides a kind of compasses that both can be used as and uses, and can be used as one-pen again and uses, and also has the pencil of plane, mill pencil stamen simultaneously, the Napier's compasses of functions such as deleading person's handwriting.

For achieving the above object, the utility model improves existing compasses, head at compasses is vertically installed a hole demountable pencil-knife up, be used to dig pencil, and paste an abrasive disc again in the side of this pencil-knife, be used to grind the pencil stamen, in a hole of this pencil-knife, be inserted in an associated erasing rubber again, be used to wipe the deleading person's handwriting.In addition, can be in order to reach as the purpose of one-pen use, that leg design that the utility model will be adorned the iron pin becomes by two poles to adopt flexible connection to combine, so just bottom pole can be folded up towards introversion, make two poles also together, form a folding pin, pin of again that this is folding compass foot and another dress stamen of compasses also gets up, utilize original stamen of compasses, promptly can be used as one-pen and used.Certainly, can incorporate into well in order to make folding pin, on the top of that compass foot of adorning a stamen, should be one section groove that can hold this folding pin to what should fold pin.This groove can hold that folding pin well, and these Napier's compasses are seemed more as if one-pen.

A stamen of existing compasses all is that single, drawn figure also is monochromatic usually, and wanting the another kind of color of picture can only the change-fountain pen stamen, very inconvenient.For several colors commonly used of conversion easily, the utility model has installed adjustable many stamens nib additional at the head of compass foot, and a stamen of different colours is housed in this nib, as long as the nib of adjusting: the stamen that just can select required color.This written structural principle is similar with the principle of the multi-color ballpoint pen of market sale now, be with some different colours the coloured pencil stamen arranged, be contained in the pen container, mix retractor device in the pen container again, there is the coloured pencil stamen to return multiple propelling movement, can selects a required stamen successively by this retractor device.

The advantage of the utility model Napier's compasses is: the compass foot of (1) dress iron pin can be folded up, and makes these compasses both can be used as compasses and uses, and can be used as one-pen again and uses; (2) the compasses head has been equipped with pencil-knife, abrasive disc, erasing rubber, can dig pencil, a mill stamen, deleading person's handwriting, makes things convenient for the user; (3) nib of compasses is adjustable many stamens nib, and the circle of the different colours that can draw also can write out the word of different colours.

Below in conjunction with accompanying drawing the utility model Napier's compasses are described in further detail.

Fig. 1 faces the expansion schematic diagram for the utility model Napier's compasses.

Fig. 2 closes up schematic diagram for facing of the utility model Napier's compasses.

As can be seen from Figure 1, the head of these Napier's compasses (4) vertically is equipped with hole pencil-knife (2) up, side at this pencil-knife, paste an abrasive disc (3), in a hole of this pencil-knife, be inserted in an erasing rubber (1), below head, a degree of tightness set screw (9) is housed, can regulates the elasticity of two compass foots with it.Both sides at this screw, but be the compass foot of two jags: wherein one of the right is to adorn iron pin (8), and it is formed by flexibly connecting point (6) flexible connection by two poles (5) (7), and bottom pole can be folded up towards introversion, form a folding pin, as shown in Figure 2.One of the left side then is the pin of a dress stamen, and what this pin top correspondence folded pin is one section groove (10) that can hold this folding pin, in the bottom of this pin, adjustable many stamens nib (11) is housed, the front that this is written is a stamen fastener (12), in order to a fixing stamen (13).
