Description
Technical field
The present invention relates to teaching aid field, be specifically related to the mini educational compasses of multipurpose.
Background technology
Compasses are one of instruments commonly used in teaching aid, and traditional educational compasses comprises two supporting legs, and wherein one is stitch, and for positioning centre, another root is paintbrush, for taking leg as center of circle picture circle.But conventional teaching compasses have some shortcomings part, such as: stitch and blackboard surface easily slide in drawing processes, the determination of radius needs to have come by other rules, drawing operates the deficiencies such as very inconvenient facade (blackboard surface) is upper.And the limited length of two legs, carry and inconvenience.Existing band tape compass, operability is very poor, and can not meet the multi-functional requirement of modern teaching.
Summary of the invention
For the deficiencies in the prior art part, the invention provides two leg compasses that a kind of easy to operate replacement is traditional, easy to carry, and serve many purposes, the multi-functional requirement of modern teaching can be met.
For realizing technique scheme, the technical solution adopted in the present invention is as follows:
The mini educational compasses of multipurpose, is characterized in that, comprise shell, vertical shaft, cotton rope, described shell is cylindrical, inside is divided into three layers, and the upper strata of shell is provided with USB flash disk, and the intermediate layer of shell is provided with laser pen, the centre position of shell lower floor arranges vertical shaft, vertical shaft upper end is fixedly connected with ratchet circle ring disk, and in the middle of circle ring disk, be fixed with torsion spring, cotton rope is wrapped on vertical shaft, cotton rope end at housing outward end, and is provided with pen clip at the end of cotton rope.
Further, at shell, lower floor is outside equipped with magnet, is fixed with sucker at magnet skin.
Further, the back side of the laser nib of shell is provided with key ring.
Further, described USB flash disk is fixed on shell by draw-in groove.
Further, described laser pen adopts button cell, and shell is provided with the switch of laser pen.
Further, what shell is also provided with ratchet circle ring disk only stops card.
Further, described one section, the card that only stops is for hook shape, and the other end is enclosed within the bearing pin that is positioned on shell, is only stopping to overlap between card and bearing pin have torsion spring.
Further, described cotton rope has scale.
The invention has the beneficial effects as follows:
1. of the present inventionly on traditional compasses, add laser pen and USB flash disk, compasses are served many purposes, meets the requirement of modern teaching;
2. compasses cotton rope of the present invention has scale, make words radius of a circle can determine, and can double jin carry out successional adjustment, simple to operate, easy to use;
3. compasses compact conformation of the present invention is simple, shell is fixed with key ring, is easy to carry.
