Button, the center of wherein magnetic clasp is provided with a jack, and fixation is inserted with chalk end in jack, because the position of magnetic clasp is very square
Just change, therefore utilize the adjustment of magnetic clasp position, it is possible to achieve the Fast Drawing of multiple concentric circles, and also the specification of concentric circles is adjusted
Section is also very rapid, and so during field research, teacher passes through without repeatedly being drawn by traditional compasses
Primary regulation, corresponding drafting demand can be realized, so as to which function is more powerful.
As further program of the utility model：The main scale is provided with the screw being through in slot, and in screw
Clamping screw is installed, passes through rotation lock bolt so that clamping screw mutually holds out against main scale and secondary ruler, so as to realize secondary ruler
Fixation.
As further program of the utility model：The main scale is made of engineering plastics, is integrally alleviated corresponding
Weight, and main scale uses integral structure with termination.
As further program of the utility model：The surface of the secondary ruler is provided with multiple grooves, convenient secondary using groove
The extraction of chi.
As further program of the utility model：The tapered structure of jack of the magnetic clasp, and the inwall gluing of jack
Rubber ring is stained with, facilitates the fixation of chalk end using rubber ring, and the jack of pyramidal structure is also convenient for the insertion of chalk end, simultaneously
Magnetic clasp individually uses under also can use as the device for being used to fix paper on blackboard.
The beneficial effects of the utility model：The utility model utilizes the adjustment of magnetic clasp position, it is possible to achieve multiple concentric circles
Fast Drawing, and the specification regulation of concentric circles is also very rapid, and so during field research, teacher is without logical
Cross traditional compasses repeatedly to be drawn, by Primary regulation, corresponding drafting demand can be realized, so as to which function is more strengthened
Greatly, while magnetic clasp is also desirable lower individually more various as the device use for being used to fix paper on blackboard, function.
