After the positioning frame 2 moves to contact with the bottom plate 4, the height of the positioning frame 2 is the height of the positioning frame 2 to be installed. After the positioning frame 2 contacts the bottom plate 4, the plug connector 61 is plugged with the first sliding part 34 through the plugging slot 63, and the plug connector 61 presses the first sliding part 34 to move towards one side far away from the rotating pipe 31 through the first inclined surface 64; thereby separating the first slider 34 from the rotating tube 31, stopping the rotation of the rotating tube 31, and stopping the downward movement of the positioning frame 2.

After the first sliding member 34 leaves the slot 35, the abutting member 71 moves away from the lead screw 11 under the action of the second spring 72, and presses the abutting member 74 upwards through the second inclined surface 75; after the pressing member 74 moves upward, the insertion block is separated from the second sliding member 22, and the second sliding member 22 losing the limiting function is inserted into the screw rod 11, so that the rotating pipe 31 rotates along with the screw rod 11.

After the rotating pipe 31 rotates, the second bevel gear 83 drives the screw to move close to one side of the steel bar column 84, so that the positioning plate 82 is inserted into the outer peripheral surface of the steel bar column 84.
