Abstract
The utility model discloses a kind of multifunctional convenient compasses, it comprises body, motion bar, sucker, on sucker, be fixed with pillar, described sucker is fixed on the body below, outboard end at described motion bar is provided with pen plughole, at the fixing little axle vertical with motion bar of the medial extremity of motion bar, is provided with axis hole on described body, described little axle is by the rotating described body top that is connected of described axis hole, and the axle center of the core of wherein said sucker and described little axle point-blank.Simple in structure, the diverse in function of the utility model, easy to use, and also easy to manufacture, with low cost, promote easily.
Description
Technical field
The utility model relates to a kind of stationery, particularly a kind of Convenient compasses with multiple function.
Background technology
The teacher gives lessons when needing picture circle or circular arc to the student at blackboard, used is traditional chevron shaped compasses or draws round with easy cotton rope, the chevron shaped compasses body of rod is long, very inconvenient for shorter user, and this chevron shaped compasses can only be single the picture circle, can not divide radian and angle easily, in addition, because the blackboard surface smoother is easy to generate slip when drawing, badly influence the effect of picture circle.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of fixedly center of circle, uses convenient multifunctional convenient compasses.
The technical solution adopted in the utility model is: a kind of multifunctional convenient compasses, it comprises body, motion bar, sucker, on sucker, be fixed with pillar, described sucker is fixed on the body below, outboard end at described motion bar is provided with pen plughole, at the fixing little axle vertical of the medial extremity of motion bar with motion bar, on described body, be provided with axis hole, described little axle is by the rotating described body top that is connected of described axis hole, and the axle center of the core of wherein said sucker and described little axle point-blank.
Be installed with an angle dial between described sucker and described body, the core of described dial and the core of described sucker are point-blank.
Described motion bar is made up of more piece, and acromere overlaps joint forms Collapsible structure in inboard connecting rod successively.
Mobilizable cover joint has a pen cap on the loop bar of described motion bar outermost end, is provided with block in the outer end of described motion bar, and described pen plughole is opened on the described pen cap.
Be marked with the length scale at described telescopic rod subscript.
Described body is an oval-shaped ball, and described little axle and described angle dial are installed in the two ends up and down of this oval-shaped ball diameter respectively.
Be provided with outwardly directed position line bar at the zero graduation place of described angle dial.
Multifunctional convenient compasses of the present utility model, compasses comprise sucker, body and motion bar, the sucker that is positioned at the body below can be adsorbed on compasses on the blackboard, because motion bar is vertical with body and rotatable by little axle, therefore, be that circle promptly can arbitrarily be drawn in the center of circle with the center of sucker, solved and drawn the bowlder center and rotate the problem that picture is justified effect that influence; In addition,, so not only can draw circle owing between body and sucker, be installed with dish at angle quarter, the suitable radian that also can draw, because motion bar is telescopic, the circle or the circular arc of the different radii that can draw use conveniently, satisfy people's needs.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, multifunctional convenient compasses of the present utility model, comprise sucker 1, on sucker 1, be fixed with pillar 10, angle dial 2, body 3, motion bar 4, body 3 is an oval-shaped ball, the center of circle of sucker 1 and angle dial 2 is fixed on the below of body 3 by screw, the medial extremity of motion bar 4 is fixed with the little axle 5 vertical with motion bar 4, little 5 by being located at the rotating top that is connected body 3 of axis hole on the body 3, wherein, the axle center of sucker 1, angle dial 2, body 3 centers of circle and little axle 5 point-blank.
Motion bar 4 is made up of every more piece, acromere can overlap joint successively on inboard loop bar, form the connecting rod of Collapsible structure, mobilizable cover joint has a pen cap 6 on the loop bar of motion bar 4 outermost end, motion bar 4 ends in the pen cap 6 outer ends are provided with block 7, on the pen cap 6, have pen plughole 8, in pen plughole 8, lay pen, in order to know drawn radius of a circle, on motion bar 4, can offer the length scale, calculate the radius of drawn circle or circular arc,, be provided with outwardly directed position line bar 9 at the zero graduation place of angle dial 2 for the ease of the location.
The utility model when in use, sucker 1 is adsorbed on the home position of required picture circle, choose needed radius by the length of adjusting motion bar 4, required circle then draws, what draw if desired is circular arc, can determine the angle of circular arc according to the angle of angle dial 2, it is fan-shaped to draw if desired, can be earlier with the limit of position line bar 9 as sector.After operation is finished, draw pillar 10 on the sucker with have gentle hands, just can easily compasses be taken off.
Simple in structure, the diverse in function of the utility model, easy to use, and also easy to manufacture, with low cost, promote easily.
