The invention discloses a movable scissor lifter. The movable scissor lifter comprises a movable base, a scissor lifting arm, a hydraulic cylinder, a lifting platform, a stand column and a positioningmechanism, wherein the scissor lifting arm is arranged above the movable base, the lifting platform is arranged above the scissor lifting arm, and the hydraulic cylinder is arranged on the scissor lifting arm; the scissor lifting arm comprises two outer arm frames and two inner arm frames; the stand column is vertically arranged on an upper surface of the movable base, and the positioning mechanism is arranged at one side of the lifting platform; the positioning mechanism comprises a T-shaped piece, an L-shaped push rod and a strip-shaped groove. By means of the mode, according to the movablescissor lifter, when the lifting platform rises to a certain height, the L-shaped push rod is pushed, so that the T-shaped piece is inserted into a groove of the stand column, the lifting platform iseffectively prevented from shaking at high altitude, and therefore the stability of the lifting platform is improved.
