Referring to fig. 1 to 12, the turnover support of the invention has the advantages that the doubling mirror is arranged on the turnover structure 2, the base 1 is arranged on the gun, the doubling mirror is matched with the red point sighting telescope on the gun, the doubling mirror can be turned over on the base 1 through the turnover structure 2, the turnover structure 2 can turn over on the base 1 by taking the whole of the ball head part 4, the turnover shaft 3 and the central shaft 5 as a rotation center, and the position of the doubling mirror is adjusted, namely when the doubling mirror is not used, the turnover structure 2 turns over to be arranged at 90 degrees with the base 1, and when the doubling mirror is used, the turnover structure 2 is turned over to lean against the base 1; when the doubling mirror is used together with the red point sighting telescope, if the red point of the red point sighting telescope is not in the center of the visual field of the doubling mirror, when the left and right adjusting bolts 661 are screwed, the adjusting seat 6 drives the turning structure 2 to swing in the left and right directions by taking the ball heads 41 on the ball head parts 4 as fulcrums through the connecting parts 62, meanwhile, the turning structure 2 can stably swing in the left and right directions on the base 1 by taking the arc-shaped bulges 101 as fulcrums, when the up and down adjusting bolts 671 are screwed, the adjusting seat 6 drives the turning structure 2 to swing in the up and down directions by taking the ball heads 41 on the ball head parts 4 as fulcrums through the connecting parts 62, meanwhile, the turning structure 2 can stably swing in the up and down directions on the base 1 by taking the arc-shaped bulges 101 as fulcrums, a shooter can know the rotating angle of the left and right adjusting bolts 661 according to the poking sounds, so that the left and right positions of the turning structure 2 can be quantitatively and accurately adjusted, the up and down positions of the turning structure 2 can be quantitatively and accurately adjusted by learning the rotating angle of the up and down adjusting bolts 671 according to poking sounds, so that the up and down positions of the turning structure 2 can be accurately aligned with the visual field of the red point sighting telescope accurately, therefore, the visual field of the magnifying glass does not need to be regulated through the regulating knob on the magnifying glass, even if a shooter carries the magnifying glass with a plurality of different times, the visual field of the magnifying glass can be aligned with the red point of the red point sighting telescope only by regulating the left regulating bolt 661 and the right regulating bolt 671 on the turnover structure 2 each time when the magnifying glass with different times is replaced, the operation is simple and quick, great convenience can be brought to the shooter, the turnover support has a simple structure, the visual field of the magnifying glass can be regulated quickly through the left regulating bolt 661 and the right regulating bolt 671 on the regulating seat 6, and the turnover support can be suitable for the magnifying glass with different times and has wide application range.
The foregoing description is only of some embodiments of the present invention, and is intended to illustrate the technical means of the present invention, not to limit the technical scope of the present invention. The present invention is obviously modified by those skilled in the art in combination with the prior common general knowledge, and falls within the protection scope of the present invention.
