1. A flexible limiting mechanism for realizing limiting of 180° forward and reverse rotation, comprising:
a base comprising a base body and a through hole passing through the base body and having a circle shape;
a first bearing mounted in the through hole and forming a fixing connection with the base body;
a turntable comprising a turntable body and a shifting lever, wherein the turntable body is in a ring shape and is inserted into the first bearing to form a fixing connection with the first bearing, the shifting lever is formed by protruding from a periphery of the turntable body, a rotational connection between the turntable body and the base body is realized through the first bearing; and
a limiting assembly, wherein the limiting assembly and the shifting lever are arranged on a same side of the base body; the limiting assembly comprises a slider slidably arranged on the base body, a limiting portion formed by protruding from a side of the slider adjacent to the turntable, and two elastic members arranged along a sliding direction of the slider and respectively fixed to two ends of the slider, respective ends of the two elastic members away from the slider are respectively fixedly connected to the base body, the limiting portion at an initial position and the shifting lever are located on a straight line of a diameter of the turntable body, and the limiting portion is spaced apart from the turntable body; two opposite sides of the base body corresponding to the limiting portion along a circumferential direction thereof are respectively provided with limiting surfaces evenly spaced from the limiting portion;
wherein the shifting lever rotating clockwise or counterclockwise to the limiting portion until the limiting portion abuts against and the limiting portion is driven to move, so that the limiting portion abuts against the limiting surface on the corresponding side to realize limiting when the shifting lever rotates by 180°.
