The invention belongs to the technical field of lifting devices, and particularly relates to an adjustable lifting device which comprises a lifting mechanism. A sliding shaft is connected to the upperside of the telescopic end of the lifting mechanism, an adjustable screw rod is arranged at the upper end of the sliding shaft, and a linear sliding bearing is slidably connected to the outer wall ofthe sliding shaft in a sleeving mode. An adjustable nut is connected to the outer wall of the adjustable screw rod in a screwed mode and located on the upper side of the linear sliding bearing, and an elastic rubber pad is connected to the outer wall of the sliding shaft in a sleeving mode and located between the adjustable nut and the linear sliding bearing. The adjustable nut is in screw threadfit with the outer wall of the adjustable screw rod so that the position of the adjustable nut on the adjustable screw rod can be adjusted, and the thread adjusting precision is high. The adjustablescrew rod has a certain adjustable space, so that the adjustable space of the whole device is further improved. Through the arrangement of the elastic rubber pad, the adjustable nut has a certain buffering effect when moving.
