Teaching aid in activity has object visual and duplicate teaching aid.Specifically there are sample or sample from nature：Such as it is used for science and technology
Biological sample, mineral sample, fossil, rock and rare animal sample in educational activities etc..But existing math teacher is used
Function is not perfect enough existing for teaching aid, and use is dumb, complex operation, lack it is interesting, and can not circuit training use, study
Train the problem of inconvenient.
The content of the invention
It is an object of the invention to provide a kind of math teacher teaching aid, is asked with solve to propose in above-mentioned background technology
Topic, possessed beneficial effect are：Perfect in shape and function, using flexible is easy and effective, interesting strong, and is easy to recycle, and learns
Train the advantages of facilitating.
To achieve the above object, the present invention provides following technical scheme：A kind of math teacher teaching aid, including rotating shaft, tooth
Wheel, digital plectrum, pen bag, clipboard, bar, driving lever, chute and handle are eliminated, the outside of the rotating shaft connects numeral by gear
Plectrum, the bottom of the rotating shaft are fixedly connected with clipboard, and the right side connection pen bag of the clipboard, the bottom of the clipboard is set
Chute is equipped with, and the chute bottom is provided with driving lever, the driving lever upper end is fixedly connected with elimination bar, the writing by chute
The left side connection handle of plate.
Further, the digital plectrum specifically uses the cylindric plectrums of PVC, and the digital plectrum is specially red, yellow
With the one or more of green, and the digital plectrum is sticked numeral.
Further, the clipboard specifically uses the internal clipboard that magnet foam is housed, and writing pencil is housed in the pen bag.
Further, the chute specifically uses rectangle channel slot.
Compared with prior art, the beneficial effects of the invention are as follows：Perfect in shape and function, using flexible is easy and effective, interesting
By force, and it is easy to recycle, the advantages of learning training facilitates, under rotating shaft and the mating reaction of gear, is dialled using numeral is stirred
Piece carries out digital combination, has reached the flexible combination effect of numeral, improves the study interest that counts, then the work for passing through clipboard
Under, write using writing pencil on clipboard, training facilitate it is direct, by eliminating being equipped with for bar and chute, profit
Carried out stirring elimination with driving lever, be easy to circuit training to write, so as to consummating function diversity, reach Best Practical effect.
