| description | The utility model discloses an automatic focusing adjustment dustproof projector, and the technical scheme is that the automatic focusing adjustment dustproof projector comprises a shielding shell, the inner wall of the top of the shielding shell is fixedly connected with a projector body, the top of the shielding shell is fixedly connected with two housings, the outer sides of the tops of the two housings are provided with a support, and the bottom of the support is fixedly connected with two installation blocks. The top of each outer shell is provided with a through hole, the bottom ends of the two installation blocks penetrate through the two through holes respectively and extend into the two outer shells, and installation mechanisms are arranged in the two outer shells. Through cooperation of the first spring and the clamping block, the state between the mounting block and the shell can be kept stable, so that mounting of the projector body can be completed, mounting is very convenient, the number of moun |
