Specifically, although the existing folding houses can reduce the transportation volume to some extent, their complex unfolding process and structural stability problems limit their widespread application. For example, the Chinese patent application with publication number CN105040820A discloses a folding integrated house, which connects the fittings first, then folds, and then unfolds using hoisting equipment after being transported to the placement position, which can effectively reduce the transportation difficulty and cost. However, the above-mentioned folding house still has the problem of difficult unfolding operation, which is still inconvenient to use. SUMMARY
