[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4As shown, a projection device includes a projector body 1, and support blocks 2 for supporting the projector body 1 are arranged at the front and rear sides of both sides of the bottom of the projector body 1, a placement groove 3 is opened in the front of the bottom of the projector body 1, and a support plate 4 is rotatably connected inside the placement groove 3, a through groove is opened on the left side of the placement groove 3, and a gear 5 is rotatably connected inside the through groove, the right side of the gear 5 is fixed to the rotating shaft of the support plate 4, a movable groove 15 is opened at the rear of the through groove, and a movable plate 6 is movably connected inside the movable groove 15, a spring 7 is fixed between one side of the movable plate 6 and the inner wall of the movable groove 15, a limiting block 8 for clamping the gear 5 is fixed on the other side of the movable plate 6, and a push plate 9 is fixed to the bottom of the movable plate 6.

[0023] Both sides of the movable plate 6 are fixedly connected with a slide plate 10, and the surface of the slide plate 10 is slidably connected to the inner wall of the movable groove 15, so that the movable plate 6 can be auxiliary supported and its stability during movement can be maintained.

[0024] A first arc groove 12 is provided on the rear surface of the placement groove 3, and the internal rotation of the first arc groove 12 is connected to a limiting plate 13. A second arc groove 14 is provided on the back of one end of the support plate 4, and one end of the limiting plate 13 is used in conjunction with the inside of the second arc groove 14, so that the support plate 4 can be auxiliary limited to prevent it from rotating.

[0025] A soft pad 11 is provided on the other side of one end of the support plate 4, and the soft pad 11 is made of rubber material, which can increase the friction between the support plate 4 and the desktop to prevent random movement.

[0026] The top surface of the rear support block 2 is rotatably connected to the bottom of the projector body 1 , so that it is convenient to adjust the angle of the projector body 1 .

[0027] The thickness of the support plate 4 is the same as the thickness of the inner side of the placement groove 3 , so that the support plate 4 will not bulge out after entering the interior of the placement groove 3 .

[0028] Working principle: When in use, in order to facilitate better projection, the push plate 9 can be driven to move backward, and the movable plate 6 can be driven to squeeze the spring 7, so that the limit block 8 is separated from the surface of the gear 5, and then the support plate 4 is driven to flip and rotate to the outside so as to contact the desktop. After that, the angle of the support plate 4 can be adjusted according to the projection position. After the adjustment is completed, the force on the push plate 9 can be canceled again, and then the limit block 8 can be driven to limit the gear 5 through the elastic force of the spring 7 itself.
