Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is described in further detail by detailed description of the invention.

First, refering to shown in Fig. 1, the multipurpose ruler tool of this utility model a kind of band compasses is main by a moment Degree plate 11 and compasses structure composition.

Graduated tile 11 is set square, and transparent material can be used to make, and graduated tile 11 is provided with semicircle Openwork part 12 and triangle openwork part 13, the arc-shaped side along semicircle openwork part 12 be provided with The angle index being gradually increased centered by the center of circle of this semicircle openwork part 12, to same direction values 121, thus constitute angle gage structure, in order to realize angle measuring function.

Compasses structure includes one first compasses leg 14 and one second compasses leg 15, and the first compasses prop up Foot 14 is rotationally connected with on graduated tile 11 by the first pivot 161, and the second compasses leg 15 is by the Two pivots 162 are rotationally connected with on graduated tile 11.Wherein, the first compasses leg 14 includes first Foot housing 141 and be inserted in the positioning needle 142 on the first leg housing 141；Second compasses leg 15 Including the second leg housing 151 and be inserted in the pen core 152 on the first leg housing 151.Utilize and turn The the first compasses leg 14 being dynamically connected on graduated tile 11 and the second compasses leg 15 constitute compasses knot Structure, it is achieved with positioning needle 142 as the center of circle, be half with the distance between positioning needle 142 and pen core 152 Footpath is drawn circle or draws circular arc, i.e. realizes calipers function.

Graduated tile 11 be provided with along graduated tile 11 while arrange gathering sill 17, the first pivot 161 Slide with the second pivot 162 and set and rotate in this gathering sill 17, so that the first compasses leg 14 Can move along gathering sill 17 with the second compasses leg 15, in order to regulation positioning needle 142 and pen core 152 Between distance, i.e. the drawn circle of regulation or the radius of circular arc, treat the first compasses leg 14 and the second compasses After leg 15 is adjusted in place, by tightening the clamp nut on the first pivot 161 and the second pivot 162 It is fixed, makes the first compasses leg 14 will not arbitrarily move with the second compasses leg 15.Along guiding Groove 17 is provided with and is gradually increased as zero point, to the two ends numerical value of gathering sill 17 with the midpoint of gathering sill 17 Length scale, it is simple to control the distance between the first compasses leg 14 and the second compasses leg 15.

Further improve as this utility model, coordinate shown in Fig. 1 and Fig. 2, graduated tile 11 sets Have and be positioned at the two ends of gathering sill 17, house for the first compasses leg 14 and the second compasses leg 15 respectively The first accommodating groove 181 and the second accommodating groove 182.First accommodating groove 181 is opened in graduated tile 11 On base and the shape adaptation of this first accommodating groove 181 is in the first leg housing of the first compasses leg 14 The shape of 141, the second accommodating groove 182 is opened on the base of graduated tile 11 and this second accommodating groove 182 Shape adaptation in the shape of the second leg housing 151 of the second compasses leg 15.First accommodating groove 181 and second accommodating groove 182 can be draw-in groove, prop up not using the first compasses leg 14 and the second compasses During foot 15, by the first pivot 161 and the second pivot 162, first compasses leg 14 and second is justified Rule leg 15 is outwards flipped up, after upset puts in place, by the first leg shell of the first compasses leg 14 Body 141 is pressed in the first accommodating groove 181, by the second leg housing 151 of the second compasses leg 15 It is pushed in the second accommodating groove 182, and then completes the first compasses leg 14 and the second compasses leg 15 Storage, positioning needle 142 is protected with pen core 152, and is easy to carry.

In the present embodiment, graduated tile 11 is right angle triangle, the center of circle of semicircle openwork part 12 Limit, place is parallel to each other with the Article 1 right-angle side of right angle triangle, and triangle openwork part 13 is right angle Triangle openwork part, the hypotenuse of this right angled triangle openwork part is straight with the Article 2 of right angle triangle The arm of angle is parallel to each other, and gathering sill 17 is arranged along the hypotenuse of right angle triangle.Graduated tile 11 also sets Having a marking-out rule 19, the side of this marking-out rule 19 is provided with length scale, the first end of this marking-out rule 19 191 are rotationally connected with on the center of circle of semicircle openwork part 12 by one the 3rd pivot 163, this line Second end 192 of chi 19 is resisted against the angle index 121 at the arc-shaped side of semicircle openwork part 12 On, utilize the place, the center of circle of the side being not provided with length scale in marking-out rule 19 and semicircle openwork part Angle between limit with opening drafting different angles, the angle of different length or line segment, or can be measured not Angle value with the angle of angle.

Above in association with drawings and Examples, this utility model is described in detail, common in this area This utility model can be made many variations example by technical staff according to the above description.Thus, in embodiment Some details should not constitute restriction of the present utility model, this utility model will be with claims The scope that book defines is as protection domain of the present utility model.
