When there is an obstacle on the outer wall of the outer wall body 1 that affects the lifting stroke of the bearing part 3, the obstacle can be effectively avoided, so that the bearing part 3 can be lifted and lowered more conveniently, thereby improving the construction work. In order to improve the efficiency of workers' construction, fixing parts 4 are provided at both ends of the bearing part 3 close to one side of the exterior wall body 1, and the two fixing parts 4 are installed in the bay window 2.

The worker performs construction work on the outer wall of the outer wall 1 by standing on the bearing part 3. By starting the lifting drive part 6, the bearing part 3 can be driven to rise and fall along the outer wall of the outer wall 1, so as to adjust the position of the worker, so that the worker can perform construction on the outer wall of the outer wall 1 more comprehensively. By starting the rotating drive part 5, the rotating drive part 5 drives the bearing part 3 to rotate, which can not only adjust the distance between the worker and the outer wall 1, but also avoid obstacles to prevent obstacles from affecting the lifting stroke of the bearing part 3 during the lifting process of the bearing part 3, so that the workers can perform construction work more conveniently. When constructing the outer wall of the outer wall 1, there is no need to drill holes in the outer wall 1 to fix the bearing part 3, which saves the later sealing operation and improves the construction efficiency of the workers.
