[0002] An existing patent (publication number: CN220415005U) proposes a forest fire lookout tower, which includes a wall, a motor fixedly connected to the interior of the wall, and a threaded rod fixedly connected to the output end of the motor. When the motor is started, the motor is connected to the threaded rod, so the threaded rod can be driven to rotate. Since the threaded rod is connected to the movable block, when the threaded rod rotates, the movable block can be driven to move up and down. Since the movable block is connected to the tension spring and the telescopic rod, it will not rotate during movement. However, in the event of a power outage due to a forest fire, workers cannot get down from the tower. Summary of the Invention
