[0004] When installing the existing elevator shaft protection device, it is necessary to adjust the spacing between the vertical rods according to the width of the door opening of the elevator shaft. When adjusting, it is necessary to first remove the connecting bolt, and then make the first rod body and the second rod body move relative to each other. After the adjustment is completed, the connecting bolt is reinserted into the adjustment hole. After adjustment, it is connected to the wall through a U-shaped clamp, and the long rod body on the rotating threaded rod is screwed. Under the transmission of the thread, the head of the rotating threaded rod drives the fixed seat to extend toward the wall until it is in close contact with the wall, and then the protective device is installed through the fixed connection between the U-shaped clamp and the wall. The installation method of the protective device in the prior art is relatively cumbersome, and the protective device cannot be installed quickly, which is inconvenient to use. Therefore, we propose a tool-type elevator shaft protection device to solve the problem raised. Utility Model Content
