Abstract

The invention relates to the technical field of Chinese teaching devices, in particular to a multifunctional teaching device for Chinese teaching, which includes a writing display board, a first chute is arranged inside the writing display board, and two extensions are slidably connected in the first chute. Writing board, two extended writing boards are symmetrically arranged left and right. The extended writing board includes a thick writing layer and a thin limiting layer. The inner bottom of the thin limiting layer is fixed with a limiting slider. The position of the slider is provided with a second chute, the limit slider is slidably connected with the second chute, the outside of the two second chute is provided with a push plate, and the push plate is connected with a linkage assembly; the present invention provides an extended writing board , when the writing area of ​​the writing display board is not enough, you can pull the extended writing board outward, when the extended writing board slides to the outermost end, turn the handle to drive the push plate to move, so that the thick writing layer and the front of the writing display board Side writing surface is flush for continuous writing.

Description
