The invention discloses a manual vertical lifting mechanism which comprises a chassis, a carrying platform and a lifting mechanism which is arranged between the chassis and the carrying platform and used for driving the carrying platform to be vertically lifted, wherein the lifting mechanism comprises a fixed piece, one or more movable pieces and a rope drum, which are arranged in sequence; the lower end of the fixed piece is fixed to the chassis; the rope drum is arranged on the carrying platform; a hand wheel used for driving the rope drum to rotate is axially arranged along the rope drum; a traction rope is wound on the rope drum; a roller wheel is arranged on the movable piece which is far away from the fixed piece and positioned on the outermost side; the traction rope penetrates through the roller wheel and is fixed to the lower end part of the movable piece on the outermost side. The manual vertical lifting mechanism adopts a pure mechanical structure and is simple in structure and low in manufacturing cost; moreover, the use of a hydraulic system is avoided, no hydraulic oil is used, external driving energy is not required, the purposes of energy conservation and environmental protection are achieved, and certain working environments with relatively strict cleaning requirements can be adapted.
