Rotatable LED table lamp with good stretching and retracting performance and adjusting method

The invention discloses a rotatable LED table lamp with good stretching and retracting performance and an adjusting method. The rotatable LED table lamp comprises a bottom plate and a lamp base fixedto the upper end face of the bottom plate through rivets, a first motor is installed on the end face of one side of the lamp base through a fixing base, an output shaft of the first motor penetrates through the side face of the lamp base and is fixedly sleeved with a screw rod, a fixing disc is fixedly installed at the bottom of the lamp base, a drive rod is longitudinally arranged in the axis ofthe top of the fixing disc, and a first gear fixedly sleeves the peripheral face of the drive rod and is in drive connection with the screw rod through threaded fitting; a first perpendicular plate and a second perpendicular plate drive a conical shell on the inner side to rotate horizontally to realize circumferential rotation of the conical shell, accordingly, a lamp cover can realize multi-direction irradiation, meanwhile, the screw rod is matched with the first gear to rotate so that speed can be more stable while the table lamp rotates circumferentially, and through the first motor and asecond motor, the ascending and descending speed of the conical shell can be adjusted according to needs when the lamp cover of the LED table lamp ascends and descends.
