A telescopic mechanism comprises three groups of telescopic unit components that are connected each other in serial in a side-by-side manner and can expand and retract simultaneously. All groups of telescopic unit components are connected in sequence in a side-by-side manner by a connecting block (2) and formed a polygonal frame structure. The telescopic unit component comprises a plurality of groups of telescopic units hinged in sequence in a head-to-end manner. The telescopic unit comprises two telescopic arms (1) which are hinged by respective central parts in a crossing manner. All groups of telescopic unit components can move synchronously so that the telescopic stability is improved, the entire telescopic mechanism is stressed uniformly, and the operating stability and the stereoscopic stability are effectively guaranteed. |
