The utility model discloses a stable type adjustable lifting seat which comprises a base, a buffer seat is fixedly connected to the interior of the base, a stabilizing
pipe is fixedly connected to the top of the buffer seat, a lifting
threaded rod is slidably connected to the interior of the stabilizing
pipe, and the outer wall, close to the stabilizing
pipe, of the lifting
threaded rod is in threaded connection with an adjusting nut. The outer wall, close to the adjusting nut, of the lifting
threaded rod is in threaded connection with a locking nut, the outer wall, close to the locking nut, of the lifting threaded rod is in threaded connection with a fixing nut, the fixing base moving upwards drives the stabilizing base to move upwards, and the stabilizing base moving upwards drives the connecting pipe to move upwards through the overturning rod. The connecting pipe moves upwards to drive the stabilizing plate to move upwards, the stabilizing plate moving upwards can make the stabilizing plate overturn around the overturning rod by limiting the limiting pipe through the locking groove, the stabilizing plate in overturning movement can overturn along with rising of the fixing base, and stability of the fixing base can be kept.
