  • Patent number: 9587671
    Abstract: A rotating mechanism, for a working lamp with a housing and a base, including a connecting column, a ball joint, and a seat; wherein a second end of the connecting column extends inside the housing; the ball joint is rotatably mounted inside the seat and a elastic member pushes the ball joint against the seat; furthermore, the connecting column relative to the housing, or the seat relative to the base, can move along the axis of the housing. A certain space may be formed between the ball joint and the seat, thereby ensuring that the ball joint performs stepless rotation of 360 degrees as required and then drives the housing on the connecting column (or seat) and the illuminant in the housing to rotate, subsequently realizing universal illumination conveniently. In the invention, light can be universally adjusted to a required angle and the purpose of reliable positioning can be realized.
