Abstract
The utility model discloses a desk lamp which comprises a lamp base, a lamp body, a support rod, and a lamp arm connected with the lamp body, wherein the support rod is connected with the lamp arm by a joint structure. The joint structure enables a tooth groove base and an adjusting base to be unidirectionally rotated due to mutually-meshed tooth grooves between a tooth shaft and the tooth groove base. The desk lamp further comprises an adjusting structure which enables the tooth groove base and the adjusting base to reversely rotate. Two ends of a double-screw bolt in the adjusting structure are respectively inserted into a first screw hole in each tooth groove and a second screw hole in an adjusting button, and a spring is clamped in a cavity between a square through hole of the adjusting base and the adjusting button and covers the double-screw bolt. The lamp arm is directly rotated when the desk lamp is forwards rotated, and the adjusting button is pressed when the desk lamp is reversely rotated, so that the tooth shaft and the tooth grooves of the tooth groove base are separated from each other, the lamp arm can be rotated, and the desk lamp can be re-fixed after the adjusting button is loosened. The desk lamp is simple in structure, easy to produce, simple and convenient to operate, free from wear to the joint structure when the desk lamp rotates, and higher in durability.
