The invention discloses a movable lifting platform for machining wood so as to increase the work height of a link mechanism lifting platform. The movable lifting platform for machining wood comprises a rack. A vertical slide groove is formed in the machine frame. A workbench is connected to the interior of the slide groove in a sliding manner. The rack is rotationally connected with a conjugate cam and a connecting rod frame. A first roller and a second roller on the connecting rod frame abut against a first cam and a second cam in the conjugate cam respectively. A motor driving the conjugate cam to rotate is arranged on the rack. A swing rod is hinged to the connecting rod frame. The driven end of the swing rod is connected with the workbench through an ejecting rod. The connecting rod frame can be pushed in a two-stage manner to rotate in the driving direction, and the function of enlarging the travel of a driven piece can be achieved.
