A turning locking platform

The utility model relates to an operation platform for target observing and aiming via turning, which provides a turning locking platform with simple structure, high positioning precision and locking function. The utility model is characterized in that: the turning locking device mainly comprises a a pin-locking type rotating mechanism used to turn a front carrier 21 and a pin-locking type locking mechanism used for locking and positioning; a rotating shaft 27 is provided with two positioning slots that are respectively used to be matched with the rotating mechanism for positioning at linear state or turning state and another two positioning slots that are respectively used to be matched with the locking mechanism for positioning at linear state or turning state. The utility model adopts two pin-locking positioning structures with same principles that are respectively used to realize the rotating mechanism used to turn the front carrier and the locking mechanism used for locking and positioning.
