[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the ceiling is used in windy weather, the ceiling has an upward and downward buffering effect to prevent the ceiling from being damaged; when used in rainy days, rainwater above the ceiling flows into the water collection frame through three rows of multifunctional circular holes, and then is discharged to the ground through the drainage pipe joint and the external hose, preventing rainwater flowing from the ceiling from splashing onto objects below the ceiling;

[0022] In addition, when the ceiling moves upward in windy weather, outside air enters the water collecting frame through six rows of semicircular air inlet and outlet grooves, and then is discharged through three rows of multifunctional circular holes. When the ceiling moves downward in windy weather, outside air enters the water collecting frame through three rows of multifunctional circular holes, and then is discharged through six rows of semicircular air inlet and outlet grooves, which reduces the resistance between the ceiling and strong wind and helps to improve the buffering effect of the ceiling.

[0023] 2. The present invention facilitates the staff to fix the installation base through the multifunctional rod; when installing the multifunctional rod, the staff can place the external wooden board on the top of the multifunctional rod, and then repeatedly hit the wooden board above the multifunctional rod with a hammer. When hitting the multifunctional rod with a hammer, the staff slightly adjusts the angle of the multifunctional rod to ensure that the four limiting protrusions are aligned with the four limiting slots, and then inserts the hexagonal wrench into the wrench matching slot, and then rotates the threaded rod with the hexagonal wrench, so that the threaded rod pushes out the four rows of active stabilizing shafts, thereby increasing the contact area between the rod and the soil, so that the multifunctional rod is more firmly inserted into the soil;

[0024] In addition, when the protection position needs to be changed, the staff uses a hex wrench to reversely rotate the threaded rod so that the top of the threaded rod contacts the limit ring. At this time, the four rows of movable stabilizing shafts are stored in four storage grooves, and then the staff pulls out the multi-function rod through four disassembly pull rings. The multi-function rod can also be pulled out through an external small lifting equipment. When using a small lifting equipment, connect the wire rope on the small lifting equipment to the four disassembly pull rings. Then the staff moves one of the corners of the installation base upward, and the corresponding moving roller automatically moves downward under the action of gravity. Then the multi-function rod is inserted into the two limit sockets until all four moving rollers are limited, which is convenient for moving to different construction sites for use.
