The embodiment of the invention discloses a rotary lifting mechanism driven by a straight stroke actuator, which comprises an actuating component, a straight stroke push rod, a two-way thrust cylindrical roller combination bearing, the straight stroke actuator, a bolt type roller needle bearing and a support cylinder, the straight stroke actuator and the bolt type roller needle bearing are fixed on the support cylinder, a spiral groove is formed in the execution component, the bidirectional thrust cylindrical roller combination bearing is fixed at the protruding end of the execution component, and the support cylinder and the straight stroke actuator are fixed on the same axis. When the straight stroke push rod does axial linear motion under the action of the straight stroke actuator, the execution component does rotary lifting motion under the action of the spiral groove and the bolt type roller needle bearing. According to the embodiment of the invention, the execution component can rotate while performing
