The invention discloses an elevating mechanism. The elevating mechanism comprises: a traveling pulley positioned on a bearing rope and rolling on the bearing rope; a connecting arm connected with the traveling pulley, wherein the end portion of the connecting arm is provided with a ratchet; and a first fixed pulley and a second fixed pulley which are symmetrically arranged, wherein the bearing rope encircles the two fixed pulleys, and the bottom of the first fixed pulley is connected with a servo motor through a belt. The servo motor is covered with a sound absorbing cover body. The elevating mechanism comprises the traveling pulley and the connecting arm connected with the traveling pulley, and the end portion of the connecting arm is provided with the ratchet, so the elevating mechanism can freely travel as needed; and the servo motor is covered with the sound absorbing cover body, so quietness and noiselessness in the working process are guaranteed.
