[0002] When construction workers are working at heights, they often use a multi-directional adjustment lifting platform. During the process of construction workers standing on the lifting platform to clean high-rise buildings, a lot of sundries and garbage will be generated.

[0003] For example, the existing application number CN202221819859.1 discloses a lifting platform, which includes a bearing platform, a lifting bracket, a driving device, a chassis, a support rod and a linkage mechanism. The lifting bracket is arranged on the chassis, the bearing platform is arranged on the lifting bracket, the support rod is arranged on the chassis, and the linkage mechanism is arranged between the lifting bracket and the support rod; the driving device is arranged on the chassis and can drive the lifting bracket to unfold or fold; the lifting bracket drives the bearing platform away from the chassis and at the same time drives the support rod to unfold through the linkage mechanism, or drives the bearing platform close to the chassis and at the same time drives the support rod to fold through the linkage mechanism; when the lifting platform of this utility model rises, it automatically opens the support, and when it descends, it automatically retracts the support, which is convenient and safe to use.
