The invention relates to the technical field of experiment table equipment, in particular to a central experiment table with an all-wood structure. The central experiment table comprises a main tablebody and a transmission motor mounted inside the main table body. According to the central experiment table with the all-wood structure, a transverse sliding slot with a built-in left turnover operating platform and a right turnover operating platform is opened in the inner lateral surface of an upper-end opening of the main table body, and lateral sliding slots matching with the left turnover operating platform and the right turnover operating platform to turn are opened on two sides of the main table body, so that a top worktable of the whole experiment table can be freely adjusted in structure and assembled and disassembled according to needs, and is very convenient and fast to use, furthermore, the transmission motor and a longitudinal transmission shaft drive a transverse transmissionshaft to rotate, and a manual sliding-type gear sleeve on the transverse transmission shaft is moved to be meshed with a gear transmission strip on the right lateral surface of a lifting display board to drive the lifting display board to lift, therefore, the lifting display board can be very conveniently controlled to lift, the display performances of the experiment table are greatly improved, and the functionality and practicality are greatly enhanced.
