The invention relates to the technical field of projection equipment, in particular to a vehicle-mounted projector with a fine adjustment mechanism and a using method thereof. The vehicle-mounted projector comprises a vehicle-mounted projector body and a base, a sound playing hole is fixedly connected to the left side of the front end face of the vehicle-mounted projector body, a shielding deviceis arranged at the front side of the sound playing hole, and the outer side of the shielding device is fixedly connected with the vehicle-mounted projector body. A lens is fixedly connected to the right side of the front end face of the vehicle-mounted projector body, a supporting device is rotatably connected to the lower end face of the vehicle-mounted projector body, a rotating shaft is arranged on the lower end face of the supporting device, and the base is arranged at the outer side of the rotating shaft. According to the vehicle-mounted projector, by arranging a rotating ball, the supporting shaft, a sliding clamping plate, the supporting rod, the sliding block, a telescopic spring and a limiting rod, the vehicle-mounted projector can be conveniently disassembled and assembled through the rotating ball and the supporting rod, the overall disassembly is not needed, and great convenience is achieved; the rotating ball is spherical, so that it is guaranteed that the vehicle-mountedprojector can rotate, and the inclination angle of the vehicle-mounted projector can be conveniently adjusted.
