Abstract

The utility model discloses a novel compass which mainly comprises a handle, a movable revolving shaft, multifunctional long feet, a pencil lead and a supporting foot. The upper end of the movable revolving shaft is connected with the fixed handle, the lower end of the movable revolving shaft is connected with two multifunctional long feet, the lower end of the left multifunctional long foot is used to hold the pencil lead, and the right multifunctional long foot is used to fixedly connect the supporting foot. The surface of the movable revolving shaft is carved with an angle scale, the middle of the angle scale is carved as zero scale, and both sides of the angle plate are symmetrical. The surfaces of the multifunctional long feet are carved with length measuring scales. The two multifunctional long feet can be laid flat in a straight line. The novel compass is simple in design and convenient to use and the like.

Description

Novel compasses

Technical field

The utility model relates to a kind of compasses, relates in particular to a kind of novel compasses.

Background technology

Existing compasses are more single on function, can not take measurement of an angle and length, simultaneously can't be regarded as ruler, and we just will be ready to these instruments such as protractor and ruler in preparation tool like this, and promptly inconvenience is also relatively wasted.

Summary of the invention

To the deficiency of prior art, the utility model provides a kind of novel compasses, its structure is: handle, movable rotation-shaft, multi-functional long pin, pencil-lead and feet are formed; The upper end of movable rotation-shaft connects fixed handle, and the lower end connects two multi-functional long pin, and the lower end of the multi-functional long pin on the left side is used for adorning pencil-lead, and the multi-functional long pin on the right is used for fixing the connection feet; Angle scale is carved with on surface at movable rotation-shaft, and the centre is a zero graduation, the both sides symmetry; The linear measure longimetry scale is carved with on the surface of multi-functional long pin; Two multi-functional long pin can point-blank keep flat.

The useful technique effect of the utility model is: the compasses in student's the instrument, protractor and ruler are combined, and the student just only need have the function that this same instrument can be realized three kinds of instruments like this, and is convenient and practical in the time of use.

Fig. 1 is the schematic perspective view of the utility model.

The specific embodiment

Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.

The structure of the utility model is: it mainly is made up of handle 1, movable rotation-shaft 2, multi-functional long pin 3, pencil-lead 4 and feet 5; The upper end of movable rotation-shaft 2 connects fixed handle 1, and the lower end connects two multi-functional long pin 3, and the lower end of the multi-functional long pin 3 on the left side is used for adorning pencil-lead 4, and the multi-functional long pin 3 on the right is used for fixing and connects feet 5; Angle scale is carved with on surface at movable rotation-shaft 2, and the centre is a zero graduation, the both sides symmetry; The linear measure longimetry scale is carved with on the surface of multi-functional long pin 3; Two multi-functional long pin 3 can point-blank keep flat.

The utility model at first is fixed on pencil-lead 4 lower end of the multi-functional long pin 3 on the left side in use, directly opens then just can be regarded as compasses and use, if when being regarded as ruler and using; Two multi-functional long pin 3 are opened point-blank, so just can be regarded as ruler, use if be regarded as protractor; Just one of them multi-functional long pin 3 is overlapped with one side of angle; Another multi-functional long pin 3 overlaps with another side, reads corresponding angle and gets final product, and is convenient and practical.

Claims (1)

1. novel compasses, it is characterized in that: it mainly is made up of handle (1), movable rotation-shaft (2), multi-functional long pin (3), pencil-lead (4) and feet (5); The upper end of movable rotation-shaft (2) connects fixed handle (1), and the lower end connects two multi-functional long pin (3), and the lower end of the multi-functional long pin (3) on the left side is used for adorning pencil-lead (4), and the multi-functional long pin (3) on the right is used for fixing and connects feet (5); Angle scale is carved with on surface at movable rotation-shaft (2), and the centre is a zero graduation, the both sides symmetry; The linear measure longimetry scale is carved with on the surface of multi-functional long pin (3); Two multi-functional long pin (3) can point-blank keep flat.
