According to the deficiencies in the prior art, there is provided a kind of simple structure, futuramic Multifunctional teaching aid.

This utility model is realized by technical scheme below：

A kind of teaching Multifunctional teaching aid, the teaching aid include a square floor, and the two ends of the lower surface of the base plate are each There is a sucker, a rotating shaft is installed on the left of the rear surface of the base plate, an expansion plate, institute are installed in the rotating shaft The front end for stating expansion plate is provided with a chalk clamp, is provided with one for support telescopic plate after the base plate on the right side of surface Supporting plate；A protractor is provided with the left of the front surface of the expansion plate, when expansion plate is rotated, protractor is also with flexible Plate is rotated together, so as to realize measuring angle；The middle of the upper surface of the base plate is provided with a level vial instrument and one Individual vertical level instrument；The scale I that precision is millimeter is provided with the front end edgewise of the upper surface of the base plate.

Preferably, the protractor is 90 degree of protractor.

Preferably, protractor of the protractor for 180 degree.

Preferably, the scale II that precision is millimeter is provided with the expansion plate.

Preferably, the chalk clamp is movably connected in the front end of expansion plate.

Preferably, the chalk clamp is arranged on the front end of expansion plate by the cooperation of threaded screw bore.

This utility model beneficial effect：

This utility model is provided with sucker, can adsorb on blackboard；Expansion plate is provided with, can be drawn different size of Circle；Protractor is provided with, angle can be measured；Scale I is provided with, the length of the length and measurement straight line of straight line can be drawn；If Level vial instrument and vertical level instrument are equipped with, horizontal line and vertical line can be drawn respectively；Chalk clamp is backed out, by expansion plate Adjustable length, can measure the depth of the objects such as bottle；This device has reached the purpose of one-object-many-purposes, in teaching practice In, with good practicality.
