Abstract
The utility model provides a lampholder and a table lamp with the lampholder applied. The lampholder comprises an upper cover and a bottom case, wherein the upper cover and the bottom case are respectively provided with a through hole and are connected through a bearing. The rotating axis of the bearing coincides with the circle center of the through holes. A balancing weight is fixedly arranged in the bottom case, and is annular or is shaped like a ring formed by a plurality of arcs. The circle center of the balancing weight coincides with the rotating axis of the bearing. The upper cover and the bottom case are divided into two parts. The upper cover can rotate relative to the bottom case through the bearing, and as the friction force of the bearing is small, the upper cover can rotate easily. In addition, the center of the base is provided with the through hole, material cost is saved, and the gravity center of the base moves downwards. Due to the annular design of the balancing weight, the gravity is dispersed to the edge, and the table lamp can be firmer.
