When installing the assembled elevator shaft frame, the frame is installed on the installation frame, and the frame is aligned with the installation slot and inserted. When inserting, the knob is turned to rotate the screw rod. When the screw rod rotates, it will drive the screw sleeve to rotate. The screw sleeve is limited by the pull rod and cannot rotate. The rotation is changed to sliding. The sliding will drive the pull rod to rotate outward, the upper pull rod shrinks, and the lower pull rod will rotate inward, thereby driving the pin to follow the movement. The pins on both sides are shrinked into the interior of the inner cavity, and the frame is inserted into the interior of the installation slot. Then, the knob is turned counterclockwise to make the screw sleeve move inward, and the pull rod rotates inward to reset.
