The invention discloses a medical alcohol cotton sealing bottle capable of being taken through internal lifting and facilitating alcohol supplement. The medical alcohol cotton sealing bottle comprises a lifting frame, a driving pore plate, a working pore plate, an adjusting rod, a driven pore plate, a support rod, a lifting platform and an alcohol bottle, wherein a driving rod is arranged at the top end of the lifting frame in a penetrating manner; and a return spring is fixedly connected to the position, located at the top end of the lifting frame, of the outer wall of the driving rod, so that the driving rod moves to drive the working pore plate to vertically rotate with the adjusting rod rotationally connected with the side wall of the lifting frame as a fulcrum through the driving pore plate. Through the arrangement of the lifting platform, in the lifting frame, the driving rod moves to drive the working pore plate to rotate with the adjusting rod as the fulcrum through the driving pore plate, the working pore plate rotates to drive the support rod to vertically slide along the side wall of the lifting frame through the driven pore plate, and the support rod moves to drive the lifting platform to slide along the inner wall of the alcohol bottle, so that the operation of taking the alcohol bottle through internal lifting is achieved.
