Abstract

Multifunctional compasses comprise two compasses arms (2), (3). Upper ends of the two compasses arms (2), (3) are hinged while lower ends thereof can be separated or combined randomly, the upper ends of the two compasses arms (2), (3) are provided with a fixed clip (1) and respectively hinged with the fixed clip (1), a pencil sharpener (5) is embedded in the fixed clip (1), and the compasses arm (3) is hinged with one end of a protractor (4) which is in the shape of an arc plate. The compasses are multifunctional, have functions of compasses, a protractor, a straight ruler and a pencil sharpener simultaneously, and are simple in structure, convenient for carrying and suitable for simple and inaccurate drawing for students of primary and middle schools.

Description

A kind of multifunctional compass

Technical field

The utility model relates to a kind of drawing and measures and use multifunctional compass.

Background technology

At present, a lot of fruitful effort were done in existing compasses design aspect multifunctional application, also once produced a lot of outstanding schemes.Wherein the general structure of multifunctional compass is that two compasses arms are main body, except the major function of compasses, also has the function of protractor concurrently.But under many circumstances, drawing and measure certain figure needs the instrument cooperation more than two just can finish the mixed and disorderly technical problem of instrument when this just causes mapping.

The utility model content

The purpose of this utility model is to provide a kind of multifunctional compass that integrates compasses, ruler, protractor and pencil-knife, the mixed and disorderly technical problem of instrument when mapping to solve.

The utility model is achieved through the following technical solutions: a kind of multifunctional compass, comprise that the upper end is hinged, and two compasses arms that the lower end can arbitrarily separate or close up are used to mould firmly with stainless steel and are done the material manufacturing.Geometrical clamp and hinged with geometrical clamp respectively is equipped with in described two compasses arms upper end; This geometrical clamp base plane is consistent with compasses arm base plane, and its inside is provided with pencil-knife with mosaic mode; Deployable 180 degree of two compasses arms, the ruler scale all is carved with in its inboard, and an end of right compasses arm and protractor is hinged; Protractor is arc sheet shape, is divided into two-section, and being that axle is folding with the rivet connects, and the 0-180 angle index all is carved with in the interior outside, spends the groove left end point as the center of circle with 90 on the right compasses arm during use.

The utility model is simple in structure, easy to use, a kind of instrument has possessed the function of compasses, ruler, protractor and pencil-knife, deployable 180 degree of two compasses arms when especially using as ruler, length is greater than 20cm, improve practicality greatly, saved raw material, reduced manufacturer's cost expenditure.

Among the figure: 1-geometrical clamp, 2-compasses arm, 3-compasses arm, 4-protractor, 5-pencil-knife, 6-handle, 7-90 degree groove.

The specific embodiment

Understanding for the ease of those skilled in the art describes in further detail the utility model below in conjunction with the drawings and specific embodiments.

Embodiment 1 is as shown in Figure 1 and Figure 2: a kind of multifunctional compass, and it is by geometrical clamp 1, compasses arm 2, compasses arm 3, protractor 4, pencil-knife 5, handle 6, nib and decide pin and form, and application is moulded firmly with stainless steel and is done the material manufacturing.Compasses arm 2,3 upper ends are equipped with geometrical clamp 1 and are articulated and connected with geometrical clamp 1 respectively.Handle 6 is equipped with in the geometrical clamp upper end, is provided with pencil-knife 5 with mosaic mode in it.Deployable 180 degree of two compasses arms, the ruler scale all is carved with in its inboard.Two compasses arm base plane are consistent with geometrical clamp 1 base plane, and mark the ruler scale on geometrical clamp 1, the covered scale in compasses arm 2,3 upper ends when using to replenish.Protractor 4 one ends and compasses arm 3 are hinged, and the 0-180 angle index all is carved with in the outside in this protractor, and 90 degree grooves, 7 left end points on can compasses arm 3 during use are as the center of circle.The rivet plane of each parts be consistent by the riveting plane.

Embodiment 2 is as shown in Figure 3: the protractor 4 of present embodiment is arc sheet shape, is divided into two-section, and being that axle is folding with the rivet connects, 90 degree graduation mark overlaids of two ends mark.

Embodiment 3 is as shown in Figure 4: the compasses arm lengths of present embodiment is 11cm, wide 1.5cm, and it is trapezoidal that the cross section is, and thickness as outside is 5～6mm, and inboard thickness is less than normal, is convenient to draw.

More than be described as the utility model preferred embodiment, under the prerequisite that does not depart from the utility model design, any conspicuous modification to the utility model carries out all should be included within the technical conceive of the present utility model.

Claims
