The invention relates to the technical field of
desk lamp parts, in particular to a rotating shaft of a
desk lamp which comprises a first rotating shaft body, a second rotating shaft body and a locking piece, a first wire groove is concavely formed in one end of the first rotating shaft body, a first wiring
pipe is arranged on the outer side wall of the first rotating shaft body, and a first threading hole communicating with the first wire groove is formed in the first wiring
pipe; a rotating shaft
cathode is convexly arranged in the first wire groove; a second wire groove is concavely formedin one end of the second rotating shaft body, a second wiring
pipe is arranged on the outer side wall of the second rotating shaft body, a second threading hole communicating with the second wire groove is formed in the second wiring pipe, a rotating shaft
anode corresponding to the rotating shaft
cathode is convexly arranged in the second wire groove, and a damping piece is arranged between the rotating shaft
anode and the rotating shaft
cathode; and the magnitude of friction damping is changed by adjusting the compression amount of the rotating shaft
anode and the rotating shaft cathode to the damping piece through the locking piece. The invention has the advantages that wires can be installed in wire grooves in the rotating shaft,
exposure risks are avoided, the structure is simple,
assembly and adjustment are convenient, threading efficiency is high, and cost is reduced.
