The invention discloses an unmanned aerial vehicle wing changing mechanism with two wings capable of changing sweepback angles synchronously and coaxially in the same plane and belongs to the technical field of unmanned aerial vehicle structural design. The unmanned aerial vehicle wing changing mechanism comprises an upper supporting board, a lower supporting board, a rotary haft, a right wing support, a left wing support, a spring, a protruding block, a limiting hook, a rack A and a rack B. The rotary shaft is connected with the lower supporting board, the left wing support, the right wing support and the upper supporting board from bottom to top. The spring is arranged between the left wing support and the lower supporting board. The rotary shaft is sleeved with the spring. By the adoption of the unmanned aerial vehicle wing changing mechanism, wings of an unmanned aerial vehicle can be folded to be stored, the storage space is reduced, and the wings can be barreled; the wings can be rapidly unfolded in the launching stage of the unmanned aerial vehicle, lift force can be established rapidly, and the situation that the height of the unmanned aerial vehicle is reduced, and even the unmanned aerial vehicle crashes can be effectively prevented; the two wings of the unmanned aerial vehicle are changed synchronously and coaxially all the time, the two wings are located on the same plane rapidly after the unmanned aerial vehicle is launched, the interference yawing moment in the transverse lateral direction can be reduced as much as possible, and control is convenient.

The invention provides an assembled building wall supporting method. The assembled building wall supporting method is mainly completed through cooperation of assembled building wall supporting equipment. The assembled building wall supporting method specifically comprises the following steps that S1, the assembled building wall supporting equipment is placed and abuts against an assembled buildingwall needing to be mounted and supported; S2, the assembled building wall supporting equipment starts to work to support the assembled building wall needing to be mounted and supported; and S3, afterthe supporting operation in the S2 is completed, the assembled building wall supporting equipment is folded and stored to be placed at a designated position. The assembled building wall supporting equipment involved in the S1 to S3 comprises a horizontal bottom plate, wherein a vertical fixing plate is fixed to the left end of the horizontal bottom plate, a movable vertical plate is rotationallyarranged at the upper end of the vertical fixing plate, and an upper limiting block is fixed to the upper portion position of the right end of the movable vertical plate. The assembled building wall supporting equipment is reasonable in structure, convenient to fold and store, and good in use effect.
