Claim:
A structure for fixing an aiming device on a gun, the fixing structure being used for attaching the aiming device to the gun, the gun having a fixing slot, the fixing structure comprising: a fixing base disposed fixedly on a top of the aiming device and formed with a containing room, wherein the fixing base is departably attached to the gun; a rotatable disk rotatably disposed at a bottom of the fixing base, the rotatable disk having two wedge-shaped components projecting from a top surface thereof, each of the wedge-shaped components having a slope, the slope having a higher end and a lower end, the higher end of the slope formed with a position-fixing concave; a locking bolt disposed within the containing room of the fixing base and capable of being moved upward or downward, the locking bolt having a lower portion formed with two position-fixing blocks; and two elastic components disposed between the fixing base and the locking bolt; wherein the two wedge-shaped components push the locking bolt upward into the fixing slot of the gun, and the position-fixing blocks are placed correspondingly into the position-fixing concaves when the rotatable disk is rotated to make the higher ends of the two wedge-shaped components move to underneath of the locking bolt; and the locking bolt is pushed downward to a lower position by the two elastic components and thus departed from the fixing slot of the gun when the rotatable disk is rotated to make the lower ends of the two wedge-shaped components move to the underneath of the locking bolt.
