Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of educational projector suspension apparatus, its structure as shown in Figure 1-2, including：
At the top of pipe-hanging hook 3-1, intermediate support 2-1 and mounting bracket 1-1, mounting bracket 1-1 there is setscrew to install
Hole；
The left side of the intermediate support 2-1 is fixedly connected with the first otic placode 2-2, and right side is fixedly connected with the second otic placode 2-5,
Having on first otic placode 2-2 has the first arcuate socket 2-6 on hinge hole, the second otic placode；
Intermediate support 2-1 inside is fixedly connected with head rod 2-3 and the second connecting rod 2-4 respectively；
