When the elevator malfunctions and shuts down in an emergency or is suddenly loaded with heavy goods, it will shake. By pulling the steel wire rope 8, the top plate 23 will press down on the damping spring damper 13. Then, the rotating rod 16 rotates along the first ring 15 and the second ring 17, which will cause the second ring 17 to press outward on the damper 18. Through the damper 18 and the damping spring damper 13, the shaking can be quickly relieved, achieving the effects of shock absorption and limiting, thus protecting the safety of passengers. When it is necessary to inspect the main board 19, the brake motor 4 is turned on. The output end of the brake motor 4 rotates, driving the gear 12 to rotate. Through the gear 2, the sliding cover 1 can be moved along the slide groove 20 to the appropriate position, so that the main board 19 can be inspected.
