Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of projection teaching's plate, including U-shaped pedestal 1, U
The inner bottom end face of shape pedestal 1 is fixedly installed with cushion 2, and the internal slide of U-shaped pedestal 1 is equipped with board of education 3, board of education 3
Lower end two sides be symmetrically arranged with square groove 4, the internal slide of square groove 4 is equipped with block 5, and the inside of block 5 is fixedly connected with
Spring 6, the outside of block 5 are fixedly connected with square pole 7, and the opening of square groove 4 is symmetrically fixedly installed with limited block 8, limit
It is slidably connected between block 8 and square pole 7；
The both side plate of U-shaped pedestal 1 is equidistantly equipped with the first circular hole 9, and restraining position ring block 10 is fixedly mounted in the periphery of the first circular hole 9；
The internal slide of first circular hole 9 is equipped with rotating bar 11, fixed between the end and square pole 7 of rotating bar 11 to connect
It connects；
The upper and lower sides of rotating bar 11 are symmetrically fixedly installed with kelly 12, and the end of kelly 12 is fixedly installed with semicircle elastomer block
13, convenient for carrying out clamping fixed to semicircle orifice 14, so that rotating bar 11 keeps stablizing；
The inner wall surrounding of first circular hole 9 is equidistantly equipped with semicircle orifice 14, the company of sliding between semicircle orifice 14 and semicircle elastomer block 13
It connects, semicircle elastomer block 13 is allowed to be detached from semicircle orifice 14 and moved；
The left plate lower end of U-shaped pedestal 1 is equipped with open slot 15, and the internal slide of open slot 15 is equipped with drawer 16, drawer
