[0019] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0020] In order to facilitate the user to adjust the rotation angle of the projector 2 according to the desired viewing angle, reference Figure 1 , Figure 2 and Figure 3As shown, including base 1, projector 2 is set vertically above base 1, the lower surface of the base 1 is provided with angle adjusting assembly for changing the projection direction of projector 2, the base 1 is installed on the wall top through height adjusting assembly, adjusting positioning bolt 15, release the locking of lifting clamping plate 12 and fixed plate 13, can be pushed or pulled in the vertical direction of lifting adjusting plate, in turn drive the lifting of projector 2, realize the height adjustment of projector 2, and after adjusting, tighten the positioning bolt 15 again, fix the lifting clamping plate 12 after adjusting, realize the height installation of projector 2, then drive the worm 6 through the motor 5 power output end, the worm 6 is engaged with worm wheel 7, drive the rotation of worm wheel 7, make the connecting rod 10 rotate in the through hole, let the support turntable 11 drive projector 2 to rotate, can according to the angle of rotation of projector 2 to adjust the angle of rotation according to the user wants to watch the angle, simple structure.

[0021] In order to facilitate the adjustment of the height of projector 2, with reference to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the back side of the base 1 is provided with a support frame 4 through the engagement of the engagement strip 3, which provides support for the support frame 4 through the engagement of the engagement strip 3, thereby improving the stability of the motor 5 during operation. The motor 5 adopts a reversible motor 5 to facilitate adjustment, and the motor 5 is a prior art which will not be described here. The angle adjusting assembly comprises a motor 5 arranged in the support frame 4, and the power output end of the motor 5 is connected with a worm 6, and the outer side of the worm 6 is engaged with a worm gear 7. With the power output end of the motor 5 driving the worm 6 to rotate, the worm 6 is engaged with the worm gear 7 to drive the worm gear 7 to rotate. The lower surface of the base 1 is provided with four support columns 8, and the end of the support column 8 away from the base 1 is connected with a support plate 9. The worm gear 7 is arranged on the surface of the support plate 9 through a bearing seat, and the worm gear 7 is inserted with a connecting rod 10. The support plate 9 supports the worm gear 7, and under the cooperation of the bearing seat, the worm gear 7 rotates. The surface of the base 1 is provided with a through hole, and the connecting rod 10 extends to the surface of the base 1 through the through hole and is connected with a support turntable 11. The support turntable 11 is connected with the lower surface of the projector 2, and the support turntable 11 can lift the projector 2, so that the projector 2 is not connected with the base 1. In this way, when the support turntable 11 rotates, the projector 2 can be driven to rotate. The height adjusting assembly comprises two lifting clamping plates 12 arranged on both sides of the base 1, and the outer side of the lifting clamping plate 12 is provided with a fixed plate 13 connected with the ceiling. The two lifting clamping plates 12 form an independent area for placing the projector 2, and there is a certain distance between the lifting clamping plate 12 and the projector 2. When the projector 2 rotates, the corners will not touch the lifting clamping plate 12, so that the projector 2 rotates in the independent area. The surface of the lifting clamping plate 12 and the fixed plate 13 is provided with a sliding groove 14, and the sliding groove 14 is provided with a positioning bolt 15. When the positioning bolt 15 is loosened, the lifting clamping plate 12 can be raised or lowered relative to the fixed plate 13, so as to adjust the height of the projector 2. When the adjustment is completed, the positioning bolt 15 is tightened to fix the base 1, thereby fixing the height of the projector 2. There is a gap between the projector 2 and the base 1, and the lower surface of the projector 2 does not contact the base 1. In this way, after the support turntable 11 rotates, the projector 2 can be driven to rotate.

[0022] In use, first, the positioning bolt 15 is adjusted, the locking of the lifting clamping plate 12 and the fixed plate 13 is released, the lifting adjusting plate can be pushed or pulled in the vertical direction, then the lifting of the projector 2 is driven, the height of the projector 2 is adjusted, after the adjustment is completed, the positioning bolt 15 is tightened again, the adjusted lifting clamping plate 12 is fixed, the installation of the height of the projector 2 is realized, then the worm 6 is driven by the power output end of the motor 5, the worm 6 is engaged with the worm wheel 7, the rotation of the worm wheel 7 is driven, the connecting rod 10 rotates in the through hole, the support rotating disc 11 drives the projector 2 to rotate, the rotation angle of the projector 2 can be adjusted according to the viewing angle desired by the user.

[0023] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application.
