After that, tighten the nut 8 until it is clamped with the limiting plate 13, and then move the limiting rod 20 downward until the bolt 19 is inserted into the first jack 16 and the second jack 18. At this time, the anti-slip convex pad 21 is in clamping contact with the inner wall of the annular groove 22 to prevent the nut 8 from rotating during use and causing the main frame 1 to cooperate with the L-shaped buckle plate 4 to loosen the clamping of the elevator shaft wall, thereby improving the stability of the erection of the integrated elevator shaft protection device.
