Zusammenfassung:The lifting device comprises a lifting sleeve, lifting limiting grooves are formed in the outer walls of the two sides of the lifting sleeve, a vertically-downward servo motor is arranged at one end of the top of the lifting sleeve, a vertically-downward lifting threaded rod is fixedly arranged on an output shaft of the servo motor through a coupler, and the lifting threaded rod is connected with the lifting sleeve in a sleeved mode. The lifting threaded rod is located in a lifting sleeve, and the outer wall of the lifting sleeve is slidably connected with a first limiting sleeve. A stepping motor is fixedly arranged on the inner wall of a fixing cylinder on a fixing plate, an output shaft of the stepping motor drives a rubber direction adjusting disc to rotate, the rubber direction adjusting disc makes contact with the outer wall of a first limiting sleeve to generate reverse friction force, and therefore a bearing disc rotates on the outer wall of the first limiting sleeve; and after the bearing disc rotate
