Most of the existing lamps cannot adjust the installation angle, and the elevation angle of the light pole cannot be adjusted. Therefore, when the lamp is used on light poles with different roads and different elevation angles, the angle cannot be adjusted. In order to solve the above problems, there is currently a lamp cap installation angle adjustment device, which includes a fixed base, a rotating base, a connecting piece passing through the rotating base and the fixing base, and a locking piece that locks the connecting piece; the connecting piece Follow the rotating seat to rotate and cooperate with the fixed seat in a clearance; the rotating seat is embedded with an inner gear plate that is threadedly connected with the connecting piece, and the fixed seat is embedded with a toothed disc that is in a clearance fit with the connecting piece. The outer toothed disc, the opposite end faces of the inner toothed disc and the outer toothed disc are provided with meshing teeth that engage with each other. Wherein, the connecting piece is a bolt, and the locking piece is a wing nut matched with the bolt. However, there are following defects in the existing lamp cap installation angle adjustment device:

When the adjustment device is subjected to external forces such as wind blowing, the bolts are easy to loosen. When the loosening reaches the point where the meshing teeth of the inner and outer gears are completely staggered and no longer engage with each other, the rotating seat will rotate around the connecting piece under the action of gravity. Thereby the original installation angle cannot be maintained. When the bolt is further loosened, it may also cause the nut to separate from the bolt, and there is a potential safety hazard that the rotating seat and the lamp will fall and smash the vehicle or injure the pedestrian.
