Uniwafer mechanical camera shutter structure

The utility model discloses an uniwafer mechanical camera shutter structure. The utility model is characterized in that a shutter is pivoted with a shutter base, and the shutter is opened by fast impact when an impacting bar disengages from the pawn buckle part of a button pressing bar. The impacting bar is provided with a pawn buckle part which is buttoned with the pawn buckle of the button pressing bar, thus the phenomenon of mistaking shock generated when a camera is put heavily, shocked or dropped accidentally is avoided. One end of the shutter is provided with an impacted part for the impacting bar to impact, thus swinging movement is generated to open the shutter, and the switch of a flash lamp near the shutter is swiped, so the flash lamp is lit up at the moment which the shutter is opened. The shutter base is connected with a shutter spring, the two sides of the spring are respectively provided with a positioning column and a projected part, thus the shutter cannot be swung counterclockwise or clockwise by general shock or shake before the impacting from the impacting bar.
