The first power box 213 and the second power box 214 are used to protect the driving gear 216 and the driven gear 215, so that the transmission work is not affected by the outside world and the service life is improved. The two cable drums 206 make the hoisting work more stable and safer. In case of a fault, when the hoisting cable 301 drops rapidly, the internal working of the friction brake 204 can form a huge resistance, which can limit the rotation of the driven shaft 208, and further stop the hoisting cable 301 from dropping, thereby ensuring the safe operation of the central air-conditioning hoisting work, reducing material damage, and ensuring the health safety of the residents.

The contact area between the threaded pressure plate 406 and the central air-conditioning body 5 is larger, making the fixation more effective. The protective pad 407 avoids direct contact between the threaded pressure plate 406 and the central air-conditioning body 5, reducing the wear of the central air-conditioning body 5. This component has a simple structure, is easy to use for installers, and increases the scope of use.
