However, after long-term use, the bolts may become loose, resulting in an unstable connection between the base and the rotating rod. This will cause the distance between the fan blade and other components to change. If it is used again at this time, the base may be offset, causing the fan blade to collide with other components and cause damage, thus posing a safety hazard to personnel and equipment.
