[0037] The working principle of the above embodiment is:

[0038] When the foldable portable building maintenance lifting device is used, the position of the stop plate 23 can be adjusted by rotating the adjusting screw 22, so that when the stop plate 23 contacts the ground, the movement of the storage box 1 can be limited, thereby facilitating the installation and stability of the storage box 1.

[0040] When not in use, the movable plate 6 can be inferred to move toward the rotating plate 4 to achieve the folding of the guardrail, and then the rotating plate 4 can be operated to rotate to turn the folded guardrail over and make the folded guardrail fit the lifting platform 2, thereby effectively reducing the volume of the guardrail. At this time, the lifting platform 2 and the guardrail can be put into the storage box 1 by retracting the articulated frame 15, so as to achieve the purpose of facilitating storage; so that after the support plate 23 is folded, the storage box 1 can drive the lifting platform 2 to move, thereby improving the portability of the device and enhancing the practical effect of the device.
