10. A use method for interactive image projection equipment is characterized by comprising the following steps:
s1: when the projector (5) is required to be used for image interaction, the mounting plate (1) is placed on an indoor top wall body, and a bolt penetrates through the mounting hole (101) and is screwed into the wall body, so that the mounting plate (1) is mounted and fixed on the indoor top;
s2: after the projector (5) is initially installed stably, the bottom plate (6) is moved towards the direction of the connecting plate (4), so that the bottom plate (6) pushes the projector (5) to move upwards, after the top of the projector (5) is connected with the friction plate (404) on the lower side of the connecting plate (4), the position of the bottom plate (6) is guaranteed to be fixed, the locking nut (602) is moved towards the direction of the corresponding adjusting frame (402) on the locking screw (603), so that after the locking nut (602) is tightly attached to the adjusting frame (402), the friction pad (601) and the friction plate (404) extrude the projector (5), and at the moment, the stability of the projector (5) is fixed;
s3: when the projector (5) is used, a user moves the holding rod (702) upwards, so that the holding rod (702) drives the placing ring (7) to move upwards, the placing ring (7) drives the outer gear ring (701) to move out of the gear groove (4011), and at the moment, the connecting plate (4) is rotated, so that the T-shaped opening (403) in the connecting plate (4) rotates on the connecting rod (203) and the baffle (204), and meanwhile, the connecting plate (4) can drive the projector (5) to rotate by an angle;
s4: after the transverse angle rotation of the projector (5) is completed, a user releases the holding rod (702), the placing ring (7) slides downwards, and the connecting plate (4) cannot rotate at the moment because the gear ring (701) can be clamped into the gear groove (4011);
s5: when the angle of the projector (5) in the vertical direction is adjusted, a user rotates the adjusting screw cylinder (3) downwards, so that the inside of the adjusting screw cylinder (3) rotates upwards on the threaded plate (1021) and moves downwards, the push plate (301) pushes the front part of the connecting plate (4) to incline downwards, and the angle adjustment in the vertical direction is completed.
