Abstract
The utility model relates to convenient compasses. A moving target rod and scale are added on normal compasses. A circle can be made without measuring the number value on a ruler by both ends of the compasses, and the use is convenient.
Description
The utility model belongs to stationery
Compasses are drawing appliances, and in use two ends distances can be drawn circle after must arriving first and measuring numerical value on the ruler, just can't accurately use under the situation of ruler not having.
Use compasses for convenience, the utility model has designed a kind of compasses that do not need ruler.
As shown in the figure, Fig. 1 is the Convenient compasses structural representation, and compasses by the connecting of top axle (3), become common compasses by left foot (1) and right crus of diaphragm (2).Of the present utility model being characterised in that at 1/4th places of left foot (1) has hole (4), rivet (5) is arranged in the hole, be used for connecting the left end of mark post (6), on right crus of diaphragm (2), have groove (7), the right-hand member of mark post (6) is limited in the groove (7) by screw (8) and nut (9), and screw (8) is the part side's of having platform (10) in groove.The ruler scale is carved with on left foot (1) surface.
According to required radius of circle, mark post (6) is moved in the groove of right crus of diaphragm (2), because screw (8) the part side of having platform in groove, so the pointer on screw (8) head is parallel with scale all the time, the place stops at corresponding numerical value, and tightening nuts (9), just can accurately make circle.So just no longer need to measure numerical value on the ruler, made things convenient for use.Because left foot (1) figure has the ruler scale, therefore also can be used as ruler and use, increased the function of compasses.
After using the utility model, do not having the own needed circle that yet can draw more accurately under the condition of chi, thereby reaching easier, fast effect.
Claims (4)
1, Convenient compasses is because the compasses that left foot (1) and right crus of diaphragm (2) connect by top axle (3), it is characterized in that having hole (4) at 1/4th places of left foot (1), rivet (5) is arranged in the hole, be used for connecting the left end of mark post (6), have groove (7) on right crus of diaphragm (2), the right-hand member of mark post (6) is limited in the groove (7) by screw (8) and nut (9).
2, Convenient compasses according to claim 1 is characterized in that screw (8) is at groove (7) side of having, inside platform (10).
3, Convenient compasses according to claim 1 is characterized in that left and right sides pin is connecting by mark post (6).
4, Convenient compasses according to claim 1 is characterized in that there is the ruler scale on left foot (1) surface.
