A placement lifting platform includes a table board, under which a bracket, scaffolds and bases are arranged. The placement lifting platform further includes a locking structure, a constant force structure and a buffer structure. By setting the constant force structure, the buffer structure and the lock structure, a constant lifting force can be provided. The adjustability function makes the platform more convenient and smooth, its buffering avoids the unnecessary collision between parts, with the special locking structure, it has better locking effect and is practical and convenient, the use effect is optimized and the applicability is improved.
