External fixing frame system and telescopic adjusting rod

The invention relates to the field of orthopedic medical instruments, in particular to an external fixing frame system and a telescopic adjusting rod. During fine adjustment, the operating part is moved to the driving position, the operating part is in jacking fit with the movable part of the driving sleeve at the moment so that the movable part can be located at the fine adjustment position, the movable part is matched with the threaded rod through internal threads, the operating part drives the driving sleeve to rotate on the telescopic pipe, and therefore the threaded rod is driven to stretch out and draw back relative to the telescopic pipe under the action of the threads. During quick adjustment, the operating piece is moved to the disconnection position, the operating piece is separated from the movable part of the driving sleeve to enable the movable part to be in the quick adjustment position, the movable part is separated from the threaded rod, the driving sleeve directly slides on the threaded rod,
