It is described using the teaching Multifunctional teaching aid used in Multifunctional teaching aid teaching method, composition includes：Arc plate, institute
The arc plate stated is connect by connecting stud with supporting leg A, legs B respectively, and Plane Installation has nut on the supporting leg A, described
Nut inner hole be installed with the connecting stud, the supporting leg A is connect by screw with graduated scale A, and the legs B passes through
Screw is connect with graduated scale B, and by screw thread and Stud connection at the top of the legs B, the stud is along the arc plate
It is slided in the arc groove of front end.
Described uses the teaching Multifunctional teaching aid used in Multifunctional teaching aid teaching method, supporting leg A lower sections
By bolt A and top connection, it is connect below the legs B by bolt B with paintbrush, the arc plate, the branch
Leg A is rotated by screw thread and the connecting stud, the legs B along the connecting stud, and the graduated scale A is long
Ruler is spent, the graduated scale B is engineer's scale, and it is 1mm that the graduated scale A, the graduated scale B materials, which are steel plate its thickness,.
Advantageous effect：
1. the present invention is a kind of teaching Multifunctional teaching aid and method, will impart knowledge to students common length ruler, engineer's scale, compasses, angulation
Device is dexterously combined, the practicality simple in structure, easy to carry, and it is accurate to measure, and convenient for teachers' instruction, improves teaching matter
Amount.
The arc plate of the present invention is connect by connecting stud with supporting leg A, legs B respectively, and legs B is along the connecting stud
Rotation, the structure operation is convenient, using the legs B is directly rotated during compasses, passes through screw thread and stud at the top of legs B
Connection, stud are slided along the arc groove of circular arc front edge of board, the angle that there is finger tip may indicate that protractor at the top of legs B, the knot
Structure is intuitive, accurate.
By bolt A and top connection below the supporting leg A of the present invention, unclamping bolt A can rotate to top above supporting leg A
Groove in, top scrape is avoided to hurt sb.'s feelings.
Graduated scale A, the graduated scale B of the present invention is connected using sheet metal structure with screw, convenient to replace other quarters at any time
Ruler is spent, this is simple in structure, is conveniently replaceable.
Description of the drawings：
Attached drawing 1 is the structure diagram of the present invention.
Attached drawing 2 is the A-A sectional views of attached drawing 1.
Attached drawing 3 is the B-B sectional views of attached drawing 1.
