[0002] With the improvement of living standards, people have higher and higher requirements for indoor environmental comfort. Traditional room air conditioners can no longer meet the needs, so central air conditioners have been developed. When installing the central air conditioner indoor unit, it is necessary to set expansion bolts on the roof, and then place the central air conditioner indoor unit on the lifting platform and raise it to a suitable position. The staff will align the four corners of the indoor unit with the expansion bolts for installation.

[0003] Some current lifting platforms do not have clamping facilities. They just place the central air conditioner indoor unit on the placement board. When the central air conditioner indoor unit is raised, it shakes, causing the indoor unit to move. There is also a risk of falling when the indoor unit moves. When the lifting platform raises the indoor unit to a suitable position, the staff uses a stepladder to the suitable position and uses auxiliary tools to bolt the indoor unit and the expansion bolts. However, there is a deviation in the alignment of the four corners of the indoor unit and the expansion bolts, and the indoor unit needs to be adjusted. The staff has many tools in their hands, which makes it inconvenient to adjust it. Utility Model Content
