The mounting portion is hinged with the base through the rotating shaft, and a lower surface of the mounting portion is located above the base, such that the mounting portion is turned about the rotating shaft between a use position and a storage position. An upper surface of the mounting portion is structurally connected to a sight, and a lower surface of the base is structurally connected to a guide rail of a firearm. A first magnet is arranged on the lower surface of the mounting portion, and a second magnet is arranged on the upper surface of the base. When the lower surface of the mounting portion is turned to the use position toward the base, the first magnet and the second magnet are attracted to each other. ## Claims ### Claim 1 A turning support for a sight, comprising a mounting portion, a base, and a rotating shaft, wherein the mounting portion is hinged with the base through the rotating shaft, a lower surface of the mounting portion is located above the base, and the mounting portion is allowed to be turned around the rotating shaft between a use position and a storage position; an upper surface of the mounting portion is structurally connected to a sight, and a lower surface of the base is structurally connected to a guide rail of a firearm; a first magnet is arranged on the lower surface of the mounting portion, and a second magnet is arranged on an upper surface of the base; and when the lower surface of the mounting portion is turned to the use position in a direction towards the base, the first magnet and the second magnet are attracted to each other. ### Claim 2 (depends on 1) The turning support according to claim 1, wherein surfaces of the first magnet and the second magnet are attracted to each other and the surfaces are inclined and parallel to each other. ### Claim 3 (depends on 1) The turning support according to claim 1, wherein a fine adjustment screw is arranged on the upper surface of the base; a top end of the fine adjustment screw protrudes from the upper surface of the base; a stopper is arranged on the lower surface of the mounting portion; and when the lower surface of the mounting portion is turned to the use position in a direction towards the base, the stopper abuts against the top end of the fine adjustment screw. ### Claim 4 (depends on 1) The turning support according to claim 1, wherein the mounting portion or the base is detachably connected to the rotating shaft. ### Claim 5 (depends on 1) The turning support according to claim 1, wherein supporting portions extending upwards are arranged on the upper surface of the base; a pivoting portion is arranged on a side surface of the mounting portion; and the rotating shaft runs through the supporting portions and the pivoting portion, the mounting portion is allowed to be turned around the rotating shaft relative to the base. ### Claim 6 (depends on 5) The turning support according to claim 5, further comprising an elastic piece, wherein the elastic piece has a fixed end and an unfixed end, the fixed end is fixed to the upper surface of the base, and the unfixed end is provided with a deformable protrusion; the pivoting portion is provided with a first groove and a second groove, the first groove and the second groove are open outwards; when the mounting portion is located at the use position, the deformable protrusion is inserted into the first groove; and when the mounting portion is located at the storage position, the deformable protrusion is inserted into the second groove. ### Claim 7 (depends on 6) The turning support according to claim 6, wherein a mounting hole is formed in the upper surface of the base, and the fixed end is fixedly connected to the mounting hole by an adhesive. ### Claim 8 (depends on 5) The turning support according to claim 5, wherein the pivoting portion is provided with a flange protruding outwards; and when the mounting portion is located at the storage position, the flange abuts against the base. ### Claim 9 (depends on 1) The turning support according to claim 1, wherein a side surface of the mounting portion is opposite to the rotating shaft and the side surface is provided with a recess open outwards, and the mounting portion is allowed to be shifted to turn around the rotating shaft away from the base.
