[0002] The cleaning telescopic device is a common cleaning equipment in the livestock breeding industry. In the livestock breeding industry, in order to improve breeding efficiency and reduce breeding costs, livestock are often raised in a centralized manner. Especially for small livestock such as poultry, they are specially equipped with layer-type chicken cages. The layer-type chicken cage is divided into many narrow cages. The cleaning telescopic device is a device specifically for cleaning the inside of narrow cages such as layer-type chicken cages. The cleaning telescopic device includes a telescopic arm and a cleaning component. The telescopic arm extends outward to send the cleaning component into the cage for cleaning; after the cleaning is completed, the telescopic arm retracts to send the cleaning component out of the cage to prepare for the cleaning of the next cage. In the prior art, the patent with the authorization announcement number CN216403652U discloses a horizontal multi-stage telescopic arm with bidirectional drive, which can be telescoped in multiple stages; however, in real scenarios, the depth of the cage is not very deep; the telescopic arm required for cleaning the cage is only three levels or less.
