Abstract
The utility model provides a novel all-purpose sector which belongs to stationery and mainly comprises a sector body; scale marked lines are arranged on the two sides of the sector body, a sliding chute is arranged on the sector body, a drawing rod and a supporting rod are arranged in the sliding chute, a tape-measure rotating shaft is also arranged in the sector body, the tape-measure rotating shaft is connected with a tape measure, and the tape measure passes through an opening of the tape measure on the sector body. The novel all-purpose sector provided by the utility model has collimated hand and fixed rubber end, can stably draw geometric figures, and cannot break the drawing paper while ensures precise drawing; the main body with scale can directly draw a circle or an arc in a given radius; the self-carried tape-measure part can draw a larger-radius circle or arc under given conditions; the tape measure is used matching with the supporting rod and the drawing rod to draw an ellipse under given conditions.
Description
Technical field
The utility model relates to a kind of stationery, particularly a kind ofly can not damage paper, the novel all-round ruler of can conveniently draw straight line, circle and circular arc.
Background technology
The tradition compasses are simple in structure, easy to use, but have a lot of limitation to a certain extent.Particularly when drawing the circle (arc) of known conditions (radius, angle), the rule pin can have certain breakage to drawing.
Summary of the invention
The purpose of this utility model provides a kind ofly can not have damage to drawing, easy to operate, the novel all-round ruler of can draw straight line, circle and circular arc.
The purpose of this utility model is achieved in that a kind of novel all-round ruler, comprise the ruler main body, ruler main body both sides are provided with the scale graticule, and the ruler main body is provided with chute, draw bar and support bar and place in the chute, also be provided with the tape rotating shaft in the ruler main body, the tape rotating shaft is connected with tape, and tape passes the tape opening on the ruler main body, and post upper is a pressure pad, the support bar lower end is the rubber ends of band opening, and pressure pad is connected with shank.Drawing the bar upper end is handle, and the pen core dop places in the picture bar.
Novel all-round ruler provided by the utility model, pin end collimation, rubber ends is fixed, and it is stable to map, and is guaranteeing that the accurate while of mapping can not make the drawing breakage; The main scale that has scale, direct circle or the arc that just can make known radius; Carry the tape part, can make the round or arc than long radius of known conditions; Tape cooperates support bar and draws bar, can draw the known conditions ellipse.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model supporting bar structure schematic diagram.
Fig. 3 is that the utility model is drawn the bar structural representation.
The specific embodiment
The utility model adopts following structure: a kind of novel all-round ruler, comprise ruler main body 1, ruler main body 1 both sides are provided with scale graticule 5, it is characterized in that: ruler main body 1 is provided with chute 2, drawing bar 3 and support bar 4 places in the chute 2, also be provided with tape rotating shaft 7 in the ruler main body 1, tape rotating shaft 7 is connected with tape 6, and tape 6 passes the tape opening 8 on the ruler main body 1.Support bar 4 upper ends are pressure pad 9, and support bar 4 lower ends are the rubber ends 11 of band opening, and pressure pad 9 is connected with shank 10.Drawing bar 3 upper ends is handle 12, and pen core dop 13 places in the picture bar 3.
When the utility model uses, by the straight line of fixed length that can draw of the scale graticule 5 on the ruler main body 1; When drawing circle or arc, owing to draw bar 3 and support bar 4 can move in chute 2, can make the circle that needs picture or the radius of arc by scale graticule 5, depress pressure pad 8, shank 10 is moved down, bring in by the pin of shank 10 and carry out location, the center of circle, decontrol pressure pad 8, carry out the fixed support bar with rubber end 11, one hand support bar 4, the handle 12 of another hand-held picture bar 3, applied thrust gently, ruler main body 1 is rotated around support bar, make circle or arc by the pen cores in the pen core dop 13.Mapping not only can not damage drawing like this, and mapping is stable, and is efficient.
Can make bigger circle of diameter or arc by tape 6.Because tape rotating shaft 7 is connected with tape 6, tape 6 passes from ruler main body 1 by tape opening 8, determine the length of tape 6 after, promptly can support bar 4 be axle center draw diameter bigger circle or arc.
At support bar 4, draw bar 3, the ellipse of known conditions can be slightly drawn in the collaborative work of tape 6 and auxiliary picture bar down.With support bar 4 and picture bar 3 is fixing point, is fixed length with tape 6, is point with auxiliary picture bar, the ellipse or the arc of the known conditions that can slightly draw, and auxiliary picture bar can adopt common compasses.
