However, using a detachable connector design allows the chair to be broken down into multiple compact parts, stacked compactly, significantly reducing space occupied during transportation, improving transportation efficiency, and reducing transportation costs. Firstly, detachable connectors offer great convenience. Consumers do not need professional assistance; they can easily assemble the chair by referring to simple instructions. This not only saves time and effort but also allows consumers to quickly enjoy the comfort of their new chair. Secondly, detachable connectors have significant advantages. They can flexibly adjust the layout and shape of the chair according to different usage scenarios and space requirements. Whether it's a small apartment or a large villa, a suitable assembly method can be found to meet personalized needs.

The connecting pin 11 is inserted into the connecting sleeve 12 from the open end. Furthermore, the quick-connect component provided by this utility model includes a connecting seat 20 on the connecting sleeve 12. The connecting seat 20 is partially connected to the closed end of the connecting sleeve 12. Thus, the connecting seat 20 acts as a reinforcing plate at the end of the connecting sleeve 12, greatly enhancing its load-bearing capacity. When disassembly is required, the user only needs to press the pressing part of the lock handle 14 to disengage the lock tongue 15 from the lock groove 13, completing quick unlocking. Subsequently, the connecting pin 11 can be quickly disengaged from the connecting sleeve 12.

[0028] In summary, this utility model allows for quick installation and separation of the connecting sleeve and connecting pin through simple operation of the locking handle. It eliminates the need for additional detachment parts, avoiding the risk of easy loss of components. Furthermore, it simplifies operation and significantly enhances structural strength. It is suitable for the rapid installation and connection of structural components in household appliances.
