Stepping corner positioning device of corner shooting system

The invention discloses a stepping corner positioning device of a corner shooting system, which adopts a stepping mode, only rotates to a nearest positioning groove in each corner operation, and realizes accurate corner positioning. During corner positioning, the deflector rod rotates, the execution end of the deflector rod pushes the ejector rod and the ejector rod block to move backwards, the ejector rod block drives the swing rod to move backwards, the swing rod drives the tenon to move backwards till the tenon completely retreats from one limiting groove of the fan-shaped plate, and unlocking of the fan-shaped plate and rotation of the limiting block and the fan-shaped plate are completed; the releasing cap pushes the swing rod upwards, the boss of the swing rod retreats from the mortise and tenon positioning groove, the mortise and tenon moves forwards under pushing of the mortise and tenon spring to enter the other limiting groove of the limiting block, and positioning is completed. 本发明公开了一种拐角射击系统的步进转角定
