If the damper 16 is not used for a long time, the damper 16 or the shock absorbing spring 17 is rusted, and when the damper 16 and the detection spring need to be replaced, only the two pressing frames 23 need to be pressed. After the pressing frame 23 is pressed, the pressing frame 23 pushes the pressing rod 24, and the pressing rod 24 can push the driving rod 25 and the positioning frame 19 to move, so that the positioning frame 19 can be separated from the inner wall of the elevator shaft 1 to unlock the bottom plate 18, and then the bottom plate 18 and the damper 16 can be disassembled through the handle 22.
