A plurality of evenly distributed teeth 15 are fixedly connected to the top of the mounting member 14, and the teeth 15 are meshed with the gear 9. The meshing of the teeth 15 with the gear 9 can block the rotation of the driving end of the motor 7, thereby enhancing the stability of the mounting plate 2. A fixed plate 13 is fixedly connected to the inner side of the mounting block 4, and the fixed plate 13 is used to install a spring 10. The spring 10 can push the mounting member 14 to rotate. A spring 10 is fixedly connected to one side of the fixed plate 13, and one end of the spring 10 is fixedly connected to one side of the mounting member 14. A connecting shaft 12 is fixedly connected to the bottom of the mounting member 14, and the connecting shaft 12 is slidably connected to the inside of the mounting block 4. Pushing the connecting shaft 12 can separate the mounting member 14 from the gear 9. Two tension springs 6 are fixedly connected to the bottom side of the mounting plate 2, and the bottom end of the tension spring 6 is fixedly connected to the bottom side of the mounting block 4. The contraction of the tension spring 6 can pull the mounting plate 2 close to the cam 5.

[0033] Reference Figure 1 , Figure 4The bottom side of the projector 1 is provided with a mounting assembly, and the mounting assembly is used to mount the projector 1. The mounting assembly includes two connecting frames 16, and the connecting frame 16 is fixedly connected to the bottom side of the projector 1. The connecting frame 16 is slidably connected to the inside of the mounting plate 2. After the connecting frame 16 is inserted into the inside of the mounting plate 2, the projector 1 and the mounting plate 2 can be connected to each other. Two movable shafts 20 are slidably connected inside the mounting plate 2. After the movable shaft 20 is moved, it is used to mount the stopper 8. One end of the movable shaft 20 is fixedly connected to a spring 2 19, and one end of the spring 2 19 is fixedly connected to the inside of the mounting plate 2. The spring 19 can push the movable shaft 20 to move. One end of the two adjacent movable shafts 20 is fixedly connected with a stopper 8. The stopper 8 is slidably connected to the inner side of the connecting frame 16. The stopper 8 is inserted into the connecting frame 16 to fix the connecting frame 16 inside the mounting plate 2. The outer periphery of the movable shaft 20 is fixedly connected with a movable rod 18. The movable rod 18 serves to connect the movable shaft 20 and the connecting plate 17 to each other. The two adjacent movable rods 18 are fixedly connected with the connecting plate 17 on the opposite side. Pushing the connecting plate 17 can drive the stopper 8 to slide out from the inside of the connecting frame 16.

[0034] Working principle: When using the device, insert the two connection frames 16 on the bottom side of the projector 1 into the mounting plate 2, and then the multiple moving shafts inside the mounting plate 2 can be pushed by multiple springs 19 and drive the two stoppers 8 to be inserted into the two connection frames 16 respectively, so that the connection frame 16 can be fixed inside the mounting plate 2 and the projector 1 can be quickly installed. After that, the projector 1 can be used for projection. When it is necessary to adjust the projection angle of the projector 1, it is necessary to first push the connection shaft 12 to move, thereby driving the mounting member 14 to rotate so that the multiple teeth 15 are separated from the gear 9, and then start the motor 7. The driving end of the motor 7 drives the cam 5 to rotate. The rotation of the cam 5 drives the mounting plate 2 to rotate around the two support shafts 3 to adjust the projection angle of the projector 1, which is convenient for people to watch and enhance the immersive feeling of the projection. After the angle adjustment of the projector 1 is completed, the connection shaft 12 is released so that the mounting member 14 is pushed and rotated by the spring 10 so that the teeth 15 contact the gear 9, thereby blocking the rotation of the driving end of the motor 7 and enhancing the stability of the mounting plate 2.
