The invention discloses a vertical lifting mechanism. The vertical lifting mechanism comprises a base, a loading platform and a lifting mechanism which is arranged between the base and the loading platform and used for driving the loading platform to vertically lift; the lifting mechanism comprises a fixing part, at least a mobile part and a screw rod which are sequentially arranged; the lower end portion of the fixing part is fixed on the base; the lower end surface of every mobile part is provided with a chain wheel; chains are engaged to the chain wheel; the screw rod is arranged on the loading platform along the vertical direction; the screw rod can idle along the peripheral direction relative to the loading platform; a nut is engaged outside the screw rod through threads; the nut is fixedly connected with the mobile part which is far from the fixing part and arranged on the innermost side; the upper end portion of the screw rod is provided with a hand wheel which is used for driving the screw rod to rotate. The vertical lifting mechanism is a pure mechanical mechanism, simple in structure and low in manufacturing cost; avoids a hydraulic system, does not contain hydraulic oil, completely does not need driving of exterior energy, is energy-saving and environmental friendly and can be applicable to some working environments having rigorous requirements for cleaning.
